INTRODUCTION

[0002] Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for supporting machine learning components.

[0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency-division multiple access (FDMA) systems, orthogonal frequency-division multiple access (OFDMA) systems, single-carrier frequency-division multiple access (SC- FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE- Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0004] A wireless network may include a number of base stations (BSs) that can support communication for a number of user equipment (UEs). A user equipment (UE) may communicate with a base station (BS) via the downlink and uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit receive point (TRP), a new radio (NR) BS, a 5G Node B, or the like.

[0005] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate on a municipal, national, regional, and even global level. New radio (NR), which may also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), using CP-OFDM and/or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. However, as the demand for mobile broadband access continues to increase, there exists a need for further improvements in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunication standards that employ these technologies.

DETAILED DESCRIPTION

[0024] A client operating in a network may report information to a server. The information may include information associated with received signals and/or positioning information, among other examples. For example, a client may perform measurements associated with reference signals and report the measurements to a server. In some examples, the client may measure reference signals during a beam management process for channel state feedback (CSF), may measure received power of reference signals from a serving cell and/or neighbor cells, may measure signal strength of inter-radio access technology (e.g., WiFi) networks, and/or may measure sensor signals for detecting locations of one or more objects within an environment. However, reporting information to the server may consume communication and/or network resources.

[0025] To mitigate consumption of resources, a client (e.g., a UE, a base station, a transmit receive point (TRP), a network device, a low-earth orbit (LEO) satellite, a medium-earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, and/or a high elliptical orbit (HEO) satellite) may use one or more machine learning components (e.g., neural networks) that may be trained to learn dependence of measured qualities on individual parameters, isolate the measured qualities through various layers of the one or more machine learning components (also referred to as “operations”), and compress measurements in a way that limits compression loss. The client may transmit the compressed measurements to the server (e.g., a TRP, another UE, and/or a base station).

[0026] The server may decode the compressed measurements using one or more decompression operations and reconstruction operations associated with one or more machine learning components. The one or more decompression and reconstruction operations may be based at least in part on a set of features of the compressed data set to produce reconstructed measurements. The server may perform a wireless communication action based at least in part on the reconstructed measurements.

[0027] In some cases, a client and a server may be configured with a machine learning component for compressing and reconstructing information. In some cases, the machine learning component may be trained using federated learning. Federated learning is a machine learning technique that enables multiple clients to collaboratively learn neural network models, while the server does not collect the data from the clients. Federated learning techniques may involve one or more global neural network models trained from data stored on multiple clients. For example, in a Federated Averaging algorithm, the server sends the neural network model to the clients. Each client trains the received neural network model using its own data and sends back an updated neural network model to the server. The server averages the updated neural network models from the clients to obtain a new neural network model.

[0028] However, in some cases, some clients may be operating in different scenarios than other clients (e.g. indoor/outdoor, stationary in a coffee shop/mobile on a highway, and/or the like). In some cases, different clients may be subject to different implementation aspects (e.g. different form factors, different RF impairments, and/or the like). As a result, in some examples, finding a neural network model that works well on all the devices in a federated learning network in terms of physical layer link performance may be difficult.

[0029] To provide and train personalized machine learning components adapted for respective clients, a client may be configured with a classifier and a set of associated autoencoders. An autoencoder may include one or more neural networks that may be used to perform a wireless communication task (e.g., CSF computation, positioning, and/or channel demodulation). The classifier may include one or more classification networks that may be used to select an autoencoder from a set of autoencoders to use for the wireless communication task. For example, the one or more classification networks may include one or more neural networks and/or one or more predictive networks.

[0030] The classifier may select the autoencoder based at least in part on an observed environmental vector associated with the environment of the client. An observed environmental vector may include an array of observed values associated with one or more features of an environment of a client. An environment of a client may include any characteristic associated with the client that may affect an operation of the client, a signal received by the client, and/or a signal transmitted by the client. An operation of the client may include any operation that may be performed on, or in connection with, any type of information. An operation of the client may include, for example, receiving a signal, decoding a signal, demodulating a signal, processing a signal, encoding a signal, modulating a signal, and/or transmitting a signal. In some aspects, the one or more features of the environment of the client may include characteristics of the client, large scale channel characteristics, channel information, signal information, and/or image data, among other examples. In some cases, the classifier is used to select the autoencoder by determining the probability of choosing each of the autoencoders of the set of encoders for the task in a perceived environment. For example, classifier may be used to select the autoencoder that works well (or is predicted to work well) in the perceived environment.

[0031] An observed wireless communication vector may be provided to the selected autoencoder, which may be configured to perform a wireless communication task such as, for example, by providing a latent vector. The client may provide an indication of the autoencoder (e.g., an autoencoder identifier (ID)) and the latent vector to the server, which may use a decoder corresponding to the selected autoencoder to recover the observed wireless communication vector. Aspects of the techniques described herein may be used for any number of cross-node machine learning challenges including, for example, facilitating channel state feedback, facilitating positioning of the client, learning of modulation and/or waveforms for wireless communication, and/or the like.

[0032] In some aspects, one or more classifiers and one or more autoencoders may be employed at the client. A client may be a software and/or hardware entity configured to interact with a server in a client-server relationship. In some aspects, for example, a client may include a UE, a base station, a transmit receive point (TRP), a network device, an integrated access and backhaul (IAB) network node, a low-earth orbit (LEO) satellite, a medium-earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, and/or a high elliptical orbit (HEO) satellite. A classifier employed at a client may be referred to herein as a “classifier” (when it is clear from context that the classifier is employed at a client as opposed to a server) or a “client classifier.” Similarly, an autoencoder employed at a client may be referred to herein as an “autoencoder” (when it is clear from context that the autoencoder is employed at a client as opposed to a server) or a “client autoencoder.”

[0033] In some aspects, one or more autoencoders may be employed at a server. A server may be a software and/or hardware entity configured to interact with a client in a client-server relationship. In some aspects, for example, a client may include a UE, a base station, a TRP, a network device, an IAB)\ network node, an LEO satellite, an MEO satellite, a GEO satellite, and/or an HEO satellite. An autoencoder employed at a server may be referred to as an “autoencoder” (when it is clear from context that the autoencoder is employed at a server as opposed to a client) or a “server autoencoder.”

[0034] As indicated above, during the training, the autoencoders and the classifier may be collaboratively learned using the federated learning techniques. In some cases, the classifier may be learned and/or updated less frequently than the set of autoencoders. The classifier selects an autoencoder based at least in part on an observed environmental vector. The observed environmental vector may include elements that do not change or that change infrequently (e.g., client identifiers, positioning information associated with an unmoving client, antenna identifiers, and other infrequency changing environmental information). As a result, the classifier, and thus the selection of the autoencoder, may change infrequently and autoencoder selection back to the server each time a latent vector is provided to the server may result in unnecessary consumption of communication resources.

[0035] Aspects of the techniques and apparatuses described herein may facilitate autoencoder selection feedback for autoencoders in wireless communication. In some aspects, a client may receive a selection feedback configuration associated with a reporting procedure for reporting updates corresponding to at least one autoencoder index associated with one or more autoencoders selected by the client. The client may determine an update corresponding to the at least one autoencoder selection and may transmit the update based at least in part on the selection feedback configuration. The client may determine the update corresponding to the at least one autoencoder selection using a classifier. The selection feedback configuration may configure the client to provide updates in a manner that reduces consumption of communication resources. In this way, aspects described herein may facilitate use of machine learning components without increasing resource consumption unnecessarily. Aspects of the techniques described herein may be used for any number of cross-node machine learning challenges including, for example, facilitating channel state feedback, facilitating positioning of a client, and/or learning of modulation and/or waveforms for wireless communication.

[0036] A classifier and an autoencoder are examples of machine learning components. A machine learning component is a component (e.g., hardware, software, or a combination thereof) of a client that performs one or more machine learning procedures. A machine learning component may include, for example, hardware and/or software that may learn to perform a procedure without being explicitly trained to perform the procedure. A machine learning component may include, for example, a feature learning processing block and/or a representation learning processing block. A machine learning component may include one or more neural networks. A neural network may include, for example, an autoencoder.

[0037] In some aspects, an autoencoder may be configured to determine a latent vector based at least in part on an observed wireless communication vector. In some aspects, the observed wireless communication vector and the latent vector may be associated with a wireless communication task. The observed wireless communication vector may include an array of observed values associated with one or more measurements obtained in connection with a wireless communication. In some aspects, for example, the wireless communication task may include determining channel state feedback (CSF), determining positioning information associated with the client, determining a modulation associated with a wireless communication, and/or determining a waveform associated with a wireless communication. The latent vector is the output of a machine learning component that takes the observed wireless communication vector as input. The latent vector may include an array of hidden values associated with one or more aspects of the observed communication vector.

It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim. [0039] Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, or the like (collectively referred to as “elements”). These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. [0040] Various aspects may include one or more clients that may communicate with one or more servers. Clients may include software and/or hardware configured to perform one or more operations and to communicate with one or more servers. Servers may include software and/or hardware configured to perform one or more operations and to communicate with one or more clients. Clients and/or servers may be, include, be included in, and/or be implemented on any number of different types of computing devices such as, for example, network devices (e.g., wireless network devices and/or wired network devices), portable computers, laptops, tablets, workstations, personal computers, controllers, in-vehicle control networks, Intemet-of-Things (loT) devices, traffic control devices, integrated access and backhaul (IAB) nodes, user equipment (UEs), base stations, relay stations, switches, routers, customer premises equipment (CPEs), and/or vehicles (e.g., land-based vehicles, aerial vehicles, non-terrestrial vehicles, and/or water-based vehicles).

[0041] As indicated above, in some aspects, clients and/or servers may be, include, be included within, and/or be implemented on one or more wireless network devices. For example, in some aspects, a client may be, include, be included in, and/or be implemented on a UE and a server may be, include, be included in, and/or be implemented on a base station. In some aspects, a client may include a server that is configured to operate as a client. In some aspects, a server may include a client configured to operate as a server. In some aspects, one or more servers and/or one or more clients may communicate using any number of types of communication connections such as, for example, wired networks, wireless networks, multi-hop networks, and/or combinations of wired networks, wireless networks, and/or multi-hop networks.

[0042] Figs. 1 and 2, and the accompanying text below, provide examples of aspects of wireless networks and wireless network devices that may be used to implement one or more aspects of subject matter disclosed herein. Figs. 3-7, and the accompanying text, describe aspects of operations that may be performed by clients and/or servers, which may include, for example, UEs and base stations as shown in, and described in connection with, Figs. 1 and 2, and/or other implementations of clients and/or servers such as, for example, those described above. Figs. 8-13, and the accompanying text, describe examples of apparatuses for implementing clients and/or servers, in accordance with various aspects of the present disclosure. The apparatuses may include wireless network devices and/or any number of other computing devices, as indicated above in connection with clients and/or servers.

[0043] It should be noted that while aspects may be described herein using terminology commonly associated with a 5G or NR radio access technology (RAT), aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G (e.g., 6G).

[0044] Fig. 1 is a diagram illustrating an example of a wireless network 100, in accordance with the present disclosure. As indicated above, one or more aspects of the wireless network 100 may be used to implement aspects of one or more clients and servers as shown in Fig. 4, and described below in connection therewith. The wireless network 100 may be or may include elements of a 5G (NR) network and/or an LTE network, among other examples. The wireless network 100 may include a number of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 1 lOd) and other network entities. A base station (BS) is an entity that communicates with user equipment (UEs) and may also be referred to as an NR BS, a Node B, a gNB, a 5G node B (NB), an access point, a transmit receive point (TRP), or the like. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to a coverage area of a BS and/or a BS subsystem serving this coverage area, depending on the context in which the term is used. In some aspects, a base station 110 may be, include, be included in, and/or be used to implement a server such as the server 404 shown in Fig. 4 and described below. A UE may be, include, be included in, and/or be used to implement a client such as the client 402 shown in Fig. 4 and described below. In some aspects, a base station 110 may be may be, include, be included in, and/or be used to implement a client. In some aspects, a UE 120 may be, include, be included in, and/or be used to implement a server.

[0045] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs having association with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In the example shown in Fig. 1, a BS 110a may be a macro BS for a macro cell 102a, a BS 110b may be a pico BS for a pico cell 102b, and a BS 110c may be a femto BS for a femto cell 102c. A BS may support one or multiple (e.g., three) cells. The terms “eNB”, “base station”, “NR BS”, “gNB”, “TRP”, “AP”, “node B”, “5G NB”, and “cell” may be used interchangeably herein. [0046] In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a mobile BS. In some examples, the BSs may be interconnected to one another and/or to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any suitable transport network.

[0047] Wireless network 100 may also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send a transmission of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. In the example shown in Fig. 1, a relay BS 1 lOd may communicate with macro BS 110a and a UE 120d in order to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, a relay base station, a relay, or the like.

[0048] In some aspects, the wireless network 100 may include one or more non-terrestrial network (NTN) deployments in which a non-terrestrial wireless communication device may include a UE (referred to herein, interchangeably, as a “non-terrestrial UE”), a BS (referred to herein, interchangeably, as a “non-terrestrial BS” and “non-terrestrial base station”), a relay station (referred to herein, interchangeably, as a “non-terrestrial relay station”), and/or the like. As used herein, an NTN may refer to a network for which access is facilitated by a nonterrestrial UE, non-terrestrial BS, a non-terrestrial relay station, and/or the like.

[0049] The wireless network 100 may include any number of non-terrestrial wireless communication devices. A non-terrestrial wireless communication device may include a satellite, a manned aircraft system, an unmanned aircraft system (UAS) platform, and/or the like. A manned aircraft system may include an airplane, helicopter, a dirigible, and/or the like. A satellite may include a low-earth orbit (LEO) satellite, a medium-earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, and/or the like. A UAS platform may include a high-altitude platform station (HAPS), and may include a balloon, a dirigible, an airplane, and/or the like. A non-terrestrial wireless communication device may be part of an NTN that is separate from the wireless network 100. Alternatively, an NTN may be part of the wireless network 100. Satellites may communicate directly and/or indirectly with other entities in wireless network 100 using satellite communication. The other entities may include UEs (e.g., terrestrial UEs and/or non-terrestrial UEs), other satellites in the one or more NTN deployments, other types of BSs (e.g., stationary and/or ground-based BSs), relay stations, one or more components and/or devices included in a core network of wireless network 100, and/or the like.

[0050] Wireless network 100 may be a heterogeneous network that includes BSs of different types, such as macro BSs, pico BSs, femto BSs, relay BSs, or the like. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in wireless network 100. For example, macro BSs may have a high transmit power level (e.g., 5 to 40 watts) whereas pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0051] A network controller 130 may couple to a set of BSs and may provide coordination and control for these BSs. Network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with one another, e.g., directly or indirectly via a wireless or wireline backhaul. For example, in some aspects, the wireless network 100 may be, include, or be included in a wireless backhaul network, sometimes referred to as an integrated access and backhaul (IAB) network. In an IAB network, at least one base station (e.g., base station 110) may be an anchor base station that communicates with a core network via a wired backhaul link, such as a fiber connection. An anchor base station may also be referred to as an IAB donor (or lAB-donor), a central entity, a central unit, and/or the like. An IAB network may include one or more non-anchor base stations, sometimes referred to as relay base stations, IAB nodes (or lAB-nodes). The non-anchor base station may communicate directly with or indirectly with (e.g., via one or more non-anchor base stations) the anchor base station via one or more backhaul links to form a backhaul path to the core network for carrying backhaul traffic. Backhaul links may be wireless links. Anchor base station(s) and/or non-anchor base station(s) may communicate with one or more UEs (e.g., UE 120) via access links, which may be wireless links for carrying access traffic.

[0052] In some aspects, a radio access network that includes an IAB network may utilize millimeter wave technology and/or directional communications (e.g., beamforming, precoding and/or the like) for communications between base stations and/or UEs (e.g., between two base stations, between two UEs, and/or between a base station and a UE). For example, wireless backhaul links between base stations may use millimeter waves to carry information and/or may be directed toward a target base station using beamforming, precoding, and/or the like. Similarly, wireless access links between a UE and a base station may use millimeter waves and/or may be directed toward a target wireless node (e.g., a UE and/or a base station). In this way, inter-link interference may be reduced.

[0053] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout wireless network 100, and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, or the like. A UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a non-terrestrial wireless communication device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, biometric sensors/devices, wearable devices (smart watches, smart clothing, smart glasses, smart wrist bands, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicular component or sensor, smart meters/sensors, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via a wireless or wired medium.

[0054] Some UEs may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and/or location tags, that may communicate with a base station, another device (e.g., remote device), or some other entity. A wireless node may provide, for example, connectivity for or to a network (e.g., a wide area network such as Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered Intemet-of-Things (loT) devices, and/or may be implemented as may be implemented as NB-IoT (narrowband internet of things) devices. Some UEs may be considered a Customer Premises Equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as processor components and/or memory components. In some aspects, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled.

[0055] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a particular RAT and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, an air interface, or the like. A frequency may also be referred to as a carrier, a frequency channel, or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0056] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using a base station 110 as an intermediary to communicate with one another). For example, the UEs 120 may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to- vehicle (V2V) protocol or a vehicle-to-infrastructure (V2I) protocol), and/or a mesh network. In some aspects, the UE 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station 110. [0057] Devices of wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided based on frequency or wavelength into various classes, bands, channels, or the like. For example, devices of wireless network 100 may communicate using an operating band having a first frequency range (FR1), which may span from 410 MHz to 7. 125 GHz, and/or may communicate using an operating band having a second frequency range (FR2), which may span from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a “sub-6 GHz” band. Similarly, FR2 is often referred to as a “millimeter wave” band despite being different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. Thus, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies less than 6 GHz, frequencies within FR1, and/or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies within the EHF band, frequencies within FR2, and/or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and techniques described herein are applicable to those modified frequency ranges.

[0058] As shown in Fig. 1, the UE 120 may include a first communication manager 140. As described in more detail elsewhere herein, the first communication manager 140 may receive a selection feedback configuration associated with a reporting procedure for reporting updates corresponding to at least one autoencoder index associated with one or more autoencoders selected by the client; determine an update corresponding to the at least one autoencoder index; and transmit the update based at least in part on the selection feedback configuration. Additionally, or alternatively, the first communication manager 140 may perform one or more other operations described herein.

[0059] In some aspects, the base station 110 may include a second communication manager 150. As described in more detail elsewhere herein, the second communication manager 150 may transmit a selection feedback configuration associated with a reporting procedure for reporting updates corresponding to at least one autoencoder index associated with one or more autoencoders selected by a client based at least in part on a classifier; and receive an update corresponding to the at least one autoencoder index based at least in part on the selection feedback configuration. Additionally, or alternatively, the second communication manager 150 may perform one or more other operations described herein.

[0060] As indicated above, Fig. 1 is provided merely as an example. Other examples may differ from what is described with regard to Fig. 1.

[0061] Fig. 2 is a diagram illustrating an example 200 of a base station 110 in communication with a UE 120 in a wireless network 100, in accordance with the present disclosure. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T > 1 and R > 1. [0062] At base station 110, a transmit processor 220 may receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQIs) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS(s) selected for the UE, and provide data symbols for all UEs. Transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. Transmit processor 220 may also generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple -output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0063] At UE 120, antennas 252a through 252r may receive the downlink signals from base station 110 and/or other base stations and may provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) a received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller/processor 280. The term “controller/processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and/or a channel quality indicator (CQI) parameter. In some aspects, one or more components of UE 120 may be included in a housing 284.

[0064] Network controller 130 may include communication unit 294, controller/processor 290, and memory 292. Network controller 130 may include, for example, one or more devices in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0065] Antennas (e.g., antennas 234a through 234t and/or antennas 252a through 252r) may include, or may be included within, one or more antenna panels, antenna groups, sets of antenna elements, and/or antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include a set of coplanar antenna elements and/or a set of non-coplanar antenna elements. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include antenna elements within a single housing and/or antenna elements within multiple housings. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components of Fig. 2.

[0066] On the uplink, at UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, and/or CQI) from controller/processor 280. Transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, a modulator and a demodulator (e.g., MOD/DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulators and/or demodulators 254, MIMO detector 256, receive processor 258, transmit processor 264, and/or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller/processor 280) and memory 282 to perform aspects of any of the methods described herein.

[0067] At base station 110, the uplink signals from UE 120 and other UEs may be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by UE 120. Receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to controller/processor 240. Base station 110 may include communication unit 244 and communicate to network controller 130 via communication unit 244. Base station 110 may include a scheduler 246 to schedule UEs 120 for downlink and/or uplink communications. In some aspects, a modulator and a demodulator (e.g., MOD/DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modulators and/or demodulators 232, MIMO detector 236, receive processor 238, transmit processor 220, and/or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller/processor 240) and memory 242 to perform aspects of any of the methods described herein.

[0068] Controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component(s) of Fig. 2 may perform one or more techniques associated with autoencoder selection feedback for autoencoders in wireless communication, as described in more detail elsewhere herein. For example, controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component(s) of Fig. 2 may perform or direct operations of, for example, process 600 or Fig. 6, process 700 of Fig. 7, and/or other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and/or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and/or interpreting) by one or more processors of the base station 110 and/or the UE 120, may cause the one or more processors, the UE 120, and/or the base station 110 to perform or direct operations of, for example, process 600 or Fig. 6, process 700 of Fig. 7, and/or other processes as described herein. In some aspects, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and/or interpreting the instructions, among other examples.

[0069] In some aspects, a client (e.g., the UE 120) may include means for receiving a selection feedback configuration associated with a reporting procedure for reporting updates corresponding to at least one autoencoder index associated with one or more autoencoders selected by the client; means for determining an update corresponding to the at least one autoencoder index; and means for transmitting the update based at least in part on the selection feedback configuration. Additionally, or alternatively, the UE 120 may include means for performing one or more other operations described herein. In some aspects, such means may include the communication manager 140. Additionally, or alternatively, such means may include one or more other components of the UE 120 described in connection with Fig. 2, such as controller/processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and/or the like.

[0070] In some aspects, a server (e.g., the base station 110) may include means for transmitting a selection feedback configuration associated with a reporting procedure for reporting updates corresponding to at least one autoencoder index associated with one or more autoencoders selected by a client based at least in part on a classifier; and means for receiving an update corresponding to the at least one autoencoder index based at least in part on the selection feedback configuration. Additionally, or alternatively, the base station 110 may include means for performing one or more other operations described herein. In some aspects, such means may include the communication manager 150. In some aspects, such means may include one or more other components of the base station 110 described in connection with Fig.

2, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller/processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and/or the like.

[0071] While blocks in Fig. 2 are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and/or the TX MIMO processor 266 may be performed by or under the control of controller/processor 280.

[0072] As indicated above, Fig. 2 is provided merely as an example. Other examples may differ from what is described with regard to Fig. 2.

[0073] Fig. 3 is a diagram illustrating an example 300 of a classifier 310 and set of associated autoencoders 320, 330, and 340, in accordance with the present disclosure. Aspects of the example 300 may be implemented by a client (e.g., the client 402 shown in Fig. 4), a server (e.g., the server 404 shown in Fig. 4), and/or the like.

[0074] The example 300 provides an example of a representation of a relationship between the client; an observed wireless communication vector, x; a latent vector, h; an observed environmental vector, and a discrete variable, z, with K values that classify the environment based on the observed environmental vector f where z G {0,1, • • • , K — 1}, and where K is the number of autoencoders in a set of autoencoders from which the classifier may select. In some aspects, the observed environmental vector f may include one or more variables that may be observed to facilitate learning the environment of the client.

[0075] In some aspects, the latent vector h may be associated with a wireless communication task. In some aspects, the wireless communication task may include determining CSF, determining positioning information associated with the client, determining a modulation associated with a wireless communication, determining a waveform associated with a wireless communication, and/or the like.

[0076] For example, in some aspects, autoencoders may be used for compressing CSF for feeding back channel state information (CSI) to a server. In some aspects, the observed wireless communication vector x may comprise a propagation channel that the client (e.g., a UE 120) estimates based at least in part on a received channel state information reference signal (CSI- RS). The latent vector h may comprise compressed CSF to be fed back to a server (e.g., a base station 110). [0077] As shown, the classifier 310 includes a classification network 350. The set of autoencoders includes a first autoencoder 320, a second autoencoder 330, and a third autoencoder 340. In some aspects, a set of autoencoders may include two autoencoders, more than three autoencoders, and/or the like. The autoencoders 320, 330, and 340 may be regular autoencoders, variational autoencoders, and/or the like.

[0078] The classifier 310 may include a classification network 350 configured to receive an observed environmental vector, as input and to provide a probability vector, p, as output. In some aspects, the last layer of the classification network 350 may include a softmax layer 360 with the length K probability vector, p, as its output. The k-the element of the probability vector,/?, corresponds to probability of selecting the k-th autoencoder: p(z = k\f), where k indexes the autoencoder and may be referred to as an autoencoder identifier (ID).

[0079] In some aspects, the observed environmental vector f may include any number of different types of information that a client may obtain about an environment of the client. Information about the environment of the client may include information about the client (e.g., device information, configuration information, capability information, and/or the like), information about a state associated with the client (e.g., an operation state, a power state, an activation state, and/or the like), information about the location of the client (e.g., positioning information, orientation information, geographical information, motion information, and/or the like), information about an environment surrounding the client (e.g., weather information, information about obstacles to wireless signals surrounding the client, information about materials in the vicinity of the client, and/or the like), and/or the like. The observed environmental vector may be formed by concatenating one or more information indications such as those listed above.

[0080] In some aspects, for example, the observed environmental vector f may include a client identifier (ID), a client antenna configuration, a large scale channel characteristic, a CSI- RS configuration, an image obtained by an imaging device, a portion of an estimated propagation channel, and/or the like. In some aspects, for example, the large scale channel characteristic may indicate a delay spread associated with a channel, a power delay profile associated with a channel, a Doppler measurement associated with a channel, a Doppler spectrum associated with a channel, a signal to noise ratio (SNR) associated with a channel, a signal to noise plus interference ratio (SiNR) associated with a channel, a reference signal received power (RSRP), a received signal strength indicator (RSSI), and/or the like.

[0081] As shown, each autoencoder 320, 330, and 340 may include an encoder configured to receive the observed wireless communication vector x as input and to provide the latent vector h as output. The autoencoders 320, 330, and 340 also may include a decoder configured to receive the latent vector h as input and to provide (e.g., recover) the observed wireless communication vector x as output. As shown by reference number 370, in the example, the autoencoder corresponding to the highest probability (.7) is selected. In the example shown, the autoencoder ID (shown as “AE-ID”) corresponding to the highest probability is 2, which may correspond, for example, to the autoencoder 330.

[0082] In some aspects, the set of autoencoders may include a conditional autoencoder, where a selected autoencoder comprises a state of the conditional autoencoder. For example, in some aspects, an encoder of the conditional autoencoder may take the selected autoencoder ID 370 as an input along with the observed wireless communication vector x. Similarly, a decoder of the conditional autoencoder may take the selected autoencoder ID 370 as an input along with the latent vector h.

[0083] According to various aspects, the classifier 310 and set of autoencoders 320-340 may be trained before being used for inference. Training the classifier, the set of autoencoders, or a combination thereof may include using an unsupervised learning procedure. Training the set of autoencoders may include using an observed wireless communication training vector, x. In some aspects, training the set of autoencoders may include determining a set of neural network parameters that maximize a variational lower bound function (e.g., an Evidence Lower Bound (ELBO) function) corresponding to the set of autoencoders. The variational lower bound function may be based at least in part on a set of conditional probabilities of selecting one or more autoencoders of the set of autoencoders and the reconstruction loss of one or more autoencoders of the set of autoencoders. Federated learning may be used to train the classifier and/or the set of autoencoders.

[0084] In some cases, the classifier may be learned and/or updated less frequently than the set of autoencoders. The classifier selects an autoencoder based at least in part on an observed environmental vector. The observed environmental vector may include elements that do not change or that change infrequently (e.g., client identifiers, positioning information associated with an unmoving client, antenna identifiers, and other infrequency changing environmental information). As a result, the classifier, and thus the selection of the autoencoder, may change infrequently and autoencoder selection back to the server each time a latent vector is provided to the server may result in unnecessary consumption of communication resources.

[0085] Aspects of the techniques and apparatuses described herein may facilitate autoencoder selection feedback for autoencoders in wireless communication. In some aspects, a client may receive a selection feedback configuration associated with a reporting procedure for reporting updates corresponding to at least one autoencoder index associated with one or more autoencoders selected by the client. The client may determine an update corresponding to the at least one autoencoder selection and may transmit the update based at least in part on the selection feedback configuration. The selection feedback configuration may configure the client to provide updates in a manner that reduces consumption of communication resources. In this way, aspects described herein may facilitate use of machine learning components without increasing resource consumption unnecessarily. Aspects of the techniques described herein may be used for any number of cross-node machine learning challenges including, for example, facilitating channel state feedback, facilitating positioning of a client, and/or learning of modulation and/or waveforms for wireless communication.

[0086] As indicated above, Fig. 3 is provided merely as an example. Other examples may differ from what is described with regard to Fig. 3.

[0087] Fig. 4 is a diagram illustrating an example 400 of wireless communication using a classifier and an associated set of autoencoders, in accordance with the present disclosure. As shown, a client 402 and a server 404 may communicate with one another. In some aspects, the client 402 and the server 404 may communicate with one another via a wireless network (e.g., the wireless network 100 shown in Fig. 1). In some aspects, more than one client 402 and/or more than one server 404 may communicate with one another.

[0088] The client 402 and/or the server 404 may be, be similar to, include, be included in, and/or be implemented using a computing device. The computing device may include, for example, a wireless communication device a network device (e.g., a wireless network device and/or wired network device), a portable computer, a laptop, a tablet, a workstation, a personal computer, a controller, an in-vehicle control network, an loT device, a traffic control device, an IAB node, a UE, a base station, a relay station, a switch, a router, a CPE, a vehicle (e.g., land- based vehicles, aerial vehicles, non-terrestrial vehicles, and/or water-based vehicles), and/or any combination and/or For example, the client 402 may be a UE (e.g., UE 120 shown in Fig. 1) and the server 404 may be a base station (e.g., base station 110 shown in Fig. 1), and the client 402 and the server 404 may communicate via an access link. The client 402 and the server 404 may be UEs 120 that communicate via a sidelink.

[0089] As shown, the client 402 may include a first communication manager 406 (e.g., the first communication manager 140 shown in Fig. 1) that may be configured to utilize a classifier 408 and a client autoencoder 410 to perform one or more wireless communication tasks. In some aspects, the classifier 408 may be, be similar to, include, or be included in, the classifier 310 shown in Fig. 3 and described above. In some aspects, the client autoencoder 410 may be, be similar to, include, or be included in, one or more of the autoencoders 320, 330, and 340 shown in Fig. 3 and described above.

[0090] In some aspects, the client 402 may include a plurality of classifiers 408. One or more of the plurality of classifiers 408 may correspond to one or more of a plurality of communication parameters. In some aspects, the client 402 may include a plurality of autoencoders 410. One or more of the plurality of autoencoders 410 may correspond to one or more of a plurality of communication parameters. In some aspects, one or more classifiers 408 may be configured to select one or more autoencoders 410 by updating one or more autoencoder indexes. The one or more classifiers 408 may be configured to select one or more autoencoders 410 corresponding to one or more of a plurality of communication parameters. The plurality of communication parameters may indicate at least one of a component carrier, a bandwidth part, a band, a band combination, a frequency range, a use case, a neural network identifier, or a combination thereof. The use case may include, for example, at least one of a CSI derivation, a positioning measurement derivation, a demodulation of a data channel, or a combination thereof.

[0091] As shown, the classifier 408 may include a classification network 412 configured to receive an observed environmental vector, as input and to provide a probability vector,/?, as output. The classifier 408 also is configured to select an autoencoder identifier (ID) (shown as “AE”) corresponding to the highest probability in the probability vector p.

[0092] As shown, the client autoencoder 410 may include an encoder 414 configured to receive an observed wireless communication vector, x, as input and to provide a latent vector, h, as output. The client autoencoder 410 also may include a decoder 416 configured to receive the latent vector h as input and to provide the observed wireless communication vector x as output. [0093] As shown in Fig. 4, the server 404 may include a communication manager 418 (e.g., the communication manager 150) that may be configured to utilize a server autoencoder 420 to perform one or more wireless communication tasks. For example, in some aspects, the server autoencoder 420 may correspond to the selected client autoencoder 410. In some aspects, the server autoencoder 420 may be, be similar to, include, or be included in, one or more of the autoencoders 320, 330, and 340 shown in Fig. 3 and described above. In some aspects, the communication manager may select the autoencoder 320 from a set of server autoencoders based at least in part on the autoencoder ID, AE, corresponding to the selected client autoencoder 320.

[0094] In some aspects, the server autoencoder 420 may include an encoder 422 configured to receive the observed wireless communication vector x as input and to provide a latent vector h as output. The server autoencoder 420 also may include a decoder 424 configured to receive the latent vector h as input and to provide the observed wireless communication vector x as output.

[0095] As shown in Fig. 4, the client 402 may include a transceiver (shown as “Tx/Rx”) 428 that may facilitate wireless communications with a transceiver 430 of the server 404. As shown by reference number 432, for example, the server 404 may transmit a selection feedback configuration to the client 402. The selection feedback configuration may be associated with a reporting procedure for reporting updates corresponding to at least one autoencoder index (e.g., the autoencoder index AE) associated with one or more autoencoders selected by the client. [0096] In some aspects, the client 402 may determine an update corresponding to the at least one autoencoder index. The client 402 may determine the update using a classifier. For example, the client 402 may select one or more autoencoders that are additional to, or in lieu of, a last one or more autoencoders selected by the client 402. As shown by reference number 434, the client 402 may transmit, and the server 404 may receive, the update. The client 402 may transmit the update based at least in part on the selection feedback configuration.

[0097] As shown by reference number 436, the server 404 may transmit, using the transceiver 430, a wireless communication to the client 402. The wireless communication may include, for example, a reference signal such as a CSI-RS. The transceiver 428 of the client 402 may receive the wireless communication. The communication manager 406 may determine an observed wireless communication vector x based at least in part on the wireless communication. For example, in aspects in which the wireless communication is a CSI-RS, the observed wireless communication vector x may include channel state information (CSI).

[0098] As shown, the communication manager 406 may obtain an observed environmental vector f and provide the observed environmental vector f to the classifier 408. The communication manager 406 may obtain the observed environmental vector from memory, from one or more sensors, and/or the like. As shown, the classification network 412 of the classifier 408 may determine, based at least in part on the observed environmental vector f a probability vector,/?. As shown, the classifier 408 may select the autoencoder 410 based at least in part on the probability vector p.

[0099] The communication manager 406 may provide, as input, the observed wireless communication vector x to the encoder 414 of the client autoencoder 410. The encoder 414 of the client autoencoder 410 may determine, based at least in part on the observed wireless communication vector x, a latent vector, h. As shown by reference number 438, the communication manager 406 may provide the latent vector h to the transceiver 428 for transmission. As shown by reference number 440, the communication manager 406 also may provide the autoencoder ID to the transceiver 428 for transmission.

[0100] As shown by reference number 442, the transceiver 428 may transmit, and the transceiver 430 of the server 404 may receive, the autoencoder ID and the latent vector h. As shown, the communication manager 418 of the server 404 may select the server autoencoder 420 based at least in part on the autoencoder ID and may provide the latent vector h as input to the decoder 424 of the server autoencoder 420. The decoder 424 may determine (e.g., reconstruct) the observed wireless communication vector x based at least in part on the latent vector h. In some aspects, the server 404 may perform a wireless communication action based at least in part on the observed wireless communication vector x. For example, in aspects in which the observed wireless communication vector x comprises CSI, the communication manager 418 of the server 404 may use the CSI for communication grouping and/ beamforming. [0101] In some aspects, a client 402 and/or a server 404 may perform one or more additional operations. A client 402 and/or a server 404 may be configured, for example, to use one or more different types of machine learning components, to use one or more procedures and/or components in addition to, or in lieu of one or more machine learning components. For example, in some aspects, a client 402 and/or a server 404 may be configured to perform a first type of procedure in connection with a received signal and to perform a second type of procedure in connection with the received signal and/or another received signal. The first type of procedure may be performed using a first algorithm, a first processing block, and/or a first machine learning component, and the second type of procedure may be performed using a second algorithm, a second processing block, and/or a second machine learning component. In an example, a client 402 may determine a first CSI associated with a received signal using a first procedure and may determine a second CSI associated with the received signal and/or a different received signal using a second procedure.

[0102] As indicated above, Fig. 4 is provided merely as an example. Other examples may differ from what is described with regard to Fig. 4.

[0103] Fig. 5 is a diagram illustrating an example of selection feedback for machine learning components in wireless communication, in accordance with the present disclosure. As shown, a client 505 and a server 510 may communicate with one another. In some aspects, the client 505 may be, be similar to, include, or be included in the client 402 shown in Fig. 4. In some aspects, the server 510 may be, be similar to, include, or be included in the server 404 shown in Fig. 4. [0104] As shown by reference number 515, the client 505 may transmit, and the server 510 may receive, a capability report. The capability report may indicate a one or more capabilities of the client 505. For example, the capability report may indicate a number of autoencoders and/or a number of autoencoder indexes that the client 505 can support. The number of autoencoders and/or autoencoder indexes that the client 505 can support may include the number of autoencoders and/or autoencoder indexes that the client 505 is capable of processing, updating, and/or tracking simultaneously.

[0105] For example, the client 505 may support at least one autoencoders and/or autoencoder indexes. The at least one autoencoders and/or autoencoder indexes may include a plurality of autoencoders and/or a plurality of autoencoder indexes. The plurality of autoencoders and/or a plurality of autoencoder indexes may correspond to a plurality of communication parameters. In some aspects, for example, a first autoencoder and/or autoencoder index of the plurality of plurality of autoencoders and/or a plurality of autoencoder indexes may corresponds to a first communication parameter of the plurality of communication parameters, and a second autoencoder and/or autoencoder index of the plurality of plurality of autoencoders and/or a plurality of autoencoder indexes may correspond to a second communication parameter of the plurality of communication parameters. The plurality of communication parameters may indicate at least one of a component carrier, a bandwidth part, a band, a band combination, a frequency range, a use case, a neural network identifier, or a combination thereof. The use case may include at least one of a CSI derivation, a positioning measurement derivation, demodulation of a data channel, or a combination thereof.

[0106] As shown by reference number 520, the server 510 may transmit, and the client 505 may receive, a selection feedback configuration. The selection feedback configuration may be associated with a reporting procedure for reporting updates corresponding to at least one autoencoder index. The at least one autoencoder index may be based at least in part on one or more features associated with an environment of the client 505. In some aspects, the selection feedback configuration may be based at least in part on the capability report. In some aspects, the server 510 may transmit, and the client 505 may receive, an autoencoder configuration that indicates a number of autoencoders to be included in the set of autoencoders.

[0107] As shown by reference number 525, the client 505 may determining an update corresponding to the at least one autoencoder index. The classifier may include at least one neural network (e.g., at least one autoencoder). The client 505 may determine the update by selecting, based at least in part on at least one classifier, at least one autoencoder of a set of autoencoders to be used for encoding at least one observed wireless communication vector to generate at least one latent vector. The update may include a locally updated autoencoder index. A locally updated autoencoder index is an autoencoder index that is updated by the client. The update may include one or more autoencoder indexes that are different than a corresponding one or more autoencoder indexes of a previously transmitted update.

[0108] As shown by reference number 530, the client 505 may transmit, and the server 510 may receive, the update corresponding to the autoencoder index (shown as autoencoder selection update). As shown by reference number 535, the server may determine an updated selected autoencoder based at least in part on the update.

[0109] In some aspects, the client 505 may be configured to provide periodic feedback of a latent vector. In some aspects, feedback of the update corresponding to the autoencoder index may be configured in relation to the periodic feedback corresponding to the latent vector. For example, in some aspects, the client 505 may receive (e.g., from the server 510) a latent vector configuration that indicates a periodic reporting procedure for reporting updates corresponding to at least one latent vector. The latent vector configuration may be carried in at least one of a radio resource control (RRC) message, a MAC CE, or a combination thereof. [0110] The client 505 may determine an update corresponding to the at least one latent vector. The client 505 may determine the update corresponding to the at least one latent vector using a selected at least one autoencoder indicated by the received at least one updated autoencoder index. The client 505 may transmit, and the server 510 may receive, the update corresponding to the at least one latent vector based at least in part on the latent vector configuration. The at least autoencoder index may include a plurality of autoencoder indexes, and the selection feedback configuration may indicate an ordering associated with transmitting a plurality of updates corresponding to the plurality of customization feature vectors.

[OHl] The latent vector configuration may indicate a first periodicity associated with reporting updates corresponding to the at least one latent vector. The first periodicity may include an amount of time between consecutive transmissions of the updates corresponding to the at least one latent vector. The selection feedback configuration may indicate a second periodicity associated with reporting the updates corresponding to the at least one autoencoder index. The second periodicity may include an amount of time between consecutive transmissions of the updates corresponding to the at least one autoencoder index. The first periodicity may be shorter than the second periodicity.

[0112] In some aspects, the second periodicity may be defined using a scaling factor based at least in part on the first periodicity. For example, the latent vector configuration may indicate a first periodicity associated with reporting updates corresponding to the at least one latent vector and a scaling factor for determining a second periodicity relative to the first periodicity. The second periodicity may include an amount of time between consecutive transmissions of the updates corresponding to the at least one autoencoder index. In some aspects, the client 505 may determine the second periodicity based at least in part on the first periodicity and the scaling factor. The client 505 may transmit, and the server 510 may receive, an indication of the second periodicity.

[0113] The scaling factor may include an explicit scaling factor. That is, for example, the selection feedback configuration may include a scaling factor table that maps the first periodicity to one or more second periodicity options. The client 505 may select the second periodicity from the one or more second periodicity options. For example, in the CSI-Reporting scenario, the configuration may include a single periodicity for reporting the latent vector h. and an explicit or implicit scaling factor to determine the reduced periodicity of the reporting of the at least one autoencoder index. An explicit scaling factor may corresponds to a factor, a={0. 1,0.2, 0.5, 0.75} in the configuration. A table maps each periodicity, T, of the latent vector h to a different periodicity of the selected autoencoder index (AE SEL) update. For example, if T _h =100 milliseconds, then T _{AE SEL} ={ 10,20,50}”, then the client 505 can pick the value and report it to the server 510. In some aspects, the scaling factor may include an implicit scaling factor, in which the first periodicity maps to the second periodicity.

[0114] The client 505 may identify a collision between a scheduled transmission of an update corresponding to the at least one latent vector and a scheduled transmission of an update corresponding to the at least one autoencoder index. The client 505 may transmit the scheduled transmission of the update corresponding to the at least one autoencoder index based at least in part on identifying the collision.

[0115] In some aspects, the at least one autoencoder index may include a plurality of autoencoder indexes. The at least one latent vector may include a plurality of latent vectors, and the client 505 may transmit, according to an ordering, a first plurality of updates. The first plurality of updates may correspond to the plurality of autoencoder indexes and the client 505 may transmit, according to the ordering, a second plurality of updates that correspond to the plurality of latent vectors.

[0116] In some aspects, transmitting the first plurality of updates and the second plurality of updates according to the ordering may include transmitting the first plurality of updates prior to transmitting the second plurality of updates. In some aspects, transmitting the first plurality of updates and the second plurality of updates according to the ordering may include transmitting a first update of the first plurality of updates; transmitting, after transmitting the first update, a second update of the second plurality of updates; transmitting, after transmitting the second update, a third update of the first plurality of updates; and transmitting, after transmitting the third update, a fourth update of the second plurality of updates.

[0117] In some aspects, the client 505 may identify a collision between a scheduled transmission of a plurality of updates corresponding to a plurality of autoencoder indexes and an additional transmission. The client 505 may refrain from transmitting an end portion of a report comprising the plurality of updates corresponding to the plurality of autoencoder indexes based at least in part on identifying the collision.

[0118] In some aspects, the client 505 may receive a resource allocation associated with a scheduled transmission of the plurality of updates corresponding to the plurality of autoencoder indexes and an additional transmission and may determine that the resource allocation is insufficient to transmit a report comprising the plurality of updates corresponding to the plurality of autoencoder indexes. The client 505 may refrain from transmitting an end portion of the report based at least in part on determining that the resource allocation is insufficient to transmit the report.

[0119] In some aspects, the customization feature vector configuration may include an indication to transmit the update corresponding to the at least one autoencoder index based at least in part on receiving a latent vector feedback request. The latent vector feedback request may be carried in at least one of a downlink channel information (DCI) transmission, a MAC CE, or a combination thereof. In some aspects, the latent vector feedback request may include a trigger that triggers transmission of an update corresponding to the at least one latent vector, and the trigger further may trigger transmission of the update corresponding to the at least one autoencoder index.

[0120] In some aspects, the client 505 may transmit, to the server 510, a feedback resource request, wherein the feedback resource request comprises a request for a first set of resources for transmitting the update corresponding to the at least one latent vector. The feedback resource request may include a request for a second set of resources for transmitting the update corresponding to the at least one autoencoder index.

[0121] In some aspects, the client 505 may determine an occurrence of an update reporting trigger event and may transmit, based at last on determining the occurrence of the update reporting trigger event, at least one of the update corresponding to the at least one autoencoder index or the update corresponding to the at least one latent vector. In some aspects, the client 505 may determine the update corresponding to the at least one latent vector by determining a locally updated latent vector based at least in part on a previously reported autoencoder index. The client 505 may determine the update corresponding to the at least one latent vector by determining a locally updated latent vector based at least in part on a default autoencoder index. The default autoencoder index include an initial autoencoder index that was determined at an initialization phase and/or a setup phase.
