CROSS-REFERENCE TO RELATED APPLICATION

[0001] This Patent Application claims priority to U.S. Nonprovisional Patent Application No. 17/661,543, filed on April 29, 2022, entitled “MACHINE LEARNING FOR BEAM PREDICTIONS WITH CONFIDENCE INDICATIONS,” which is hereby expressly incorporated by reference herein.

FIELD OF THE DISCLOSURE

[0002] Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for machine learning for beam predictions with confidence indications.

BACKGROUND

[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 one or more base stations that support communication for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. “Downlink” (or “DL”) refers to a communication link from the base station to the UE, and “uplink” (or “UL”) refers to a communication link from the UE to the base station.

[0005] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate on a municipal, national, regional, and/or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 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, using CP-OFDM and/or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple -input multiple -output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.

DETAILED DESCRIPTION

[0024] Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. One skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using other structure, functionality, or structure and functionality in addition to or other than the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim. [0025] 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. [0026] While aspects may be described herein using terminology commonly associated with a 5G or New Radio (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).

[0027] Fig. 1 is a diagram illustrating an example of a wireless network 100, in accordance with the present disclosure. The wireless network 100 may be or may include elements of a 5G (e.g., NR) network and/or a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network 100 may include one or more base stations 110 (shown as a BS 110a, a BS 110b, a BS 110c, and a BS 1 lOd), a user equipment (UE) 120 or multiple UEs 120 (shown as a UE 120a, a UE 120b, a UE 120c, a UE 120d, and a UE 120e), and/or other network entities. A base station 110 is an entity that communicates with UEs 120. A base station 110 (sometimes referred to as a BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and/or a transmission reception point (TRP). Each base station 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term “cell” can refer to a coverage area of a base station 110 and/or a base station subsystem serving this coverage area, depending on the context in which the term is used.

[0028] A base station 110 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 120 with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs 120 having association with the femto cell (e.g., UEs 120 in a closed subscriber group (CSG)). A base station 110 for a macro cell may be referred to as a macro base station. A base station 110 for a pico cell may be referred to as a pico base station. A base station 110 for a femto cell may be referred to as a femto base station or an in-home base station. In the example shown in Fig. 1, the BS 110a may be a macro base station for a macro cell 102a, the BS 110b may be a pico base station for a pico cell 102b, and the BS 110c may be a femto base station for a femto cell 102c. A base station may support one or multiple (e.g., three) cells.

[0029] 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 base station 110 that is mobile (e.g., a mobile base station). In some examples, the base stations 110 may be interconnected to one another and/or to one or more other base stations 110 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.

[0030] The wireless network 100 may include one or more relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a base station 110 or a UE 120) and send a transmission of the data to a downstream station (e.g., a UE 120 or a base station 110). A relay station may be a UE 120 that can relay transmissions for other UEs 120. In the example shown in Fig. 1, the BS 1 lOd (e.g., a relay base station) may communicate with the BS 110a (e.g., a macro base station) and the UE 120d in order to facilitate communication between the BS 110a and the UE 120d. A base station 110 that relays communications may be referred to as a relay station, a relay base station, a relay, or the like. [0031] The wireless network 100 may be a heterogeneous network that includes base stations 110 of different types, such as macro base stations, pico base stations, femto base stations, relay base stations, or the like. These different types of base stations 110 may have different transmit power levels, different coverage areas, and/or different impacts on interference in the wireless network 100. For example, macro base stations may have a high transmit power level (e.g., 5 to 40 watts) whereas pico base stations, femto base stations, and relay base stations may have lower transmit power levels (e.g., 0. 1 to 2 watts).

[0032] A network controller 130 may couple to or communicate with a set of base stations 110 and may provide coordination and control for these base stations 110. The network controller 130 may communicate with the base stations 110 via a backhaul communication link. The base stations 110 may communicate with one another directly or indirectly via a wireless or wireline backhaul communication link.

[0033] The UEs 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. A UE 120 may include, for example, an access terminal, a terminal, a mobile station, and/or a subscriber unit. A UE 120 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 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, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and/or a satellite radio), a vehicular component or sensor, a smart meter/sensor, industrial manufacturing equipment, a global positioning system device, and/or any other suitable device that is configured to communicate via a wireless medium.

[0034] Some UEs 120 may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. An MTC UE and/or an eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, and/or a location tag, that may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Intemet-of-Things (loT) devices, and/or may be implemented as NB-IoT (narrowband loT) devices. Some UEs 120 may be considered a Customer Premises Equipment. A UE 120 may be included inside a housing that houses components of the UE 120, such as processor components and/or memory components. In some examples, 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.

[0035] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, an air interface, or the like. A frequency may 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.

[0036] In some examples, 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, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), and/or a mesh network. In such examples, a UE 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station 110.

[0037] Devices of the wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, channels, or the like. For example, devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “Sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, 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.

[0038] The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz - 24.25 GHz). Frequency bands falling within FR3 may inherit FR1 characteristics and/or FR2 characteristics, and thus may effectively extend features of FR1 and/or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz - 71 GHz), FR4 (52.6 GHz - 114.25 GHz), and FR5 (114.25 GHz - 300 GHz).

Each of these higher frequency bands falls within the EHF band.

[0039] With the above examples in mind, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and/or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and/or FR5) may be modified, and techniques described herein are applicable to those modified frequency ranges.

[0040] In some aspects, a UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive a signal; determine , based at least in part on a machine learning component, a predicted communication metric and a confidence indication, the machine learning component comprising a machine learning model, and wherein determining the predicted communication metric and the confidence indication comprises: receive an input that comprises an input metric and an error measurement corresponding to the input metric; and provide and based at least in part on a machine learning function and the input, the predicted communication metric and the confidence indication; and perform a wireless communication task based at least in part on the predicted communication metric and the confidence indication. Additionally, or alternatively, the communication manager 140 may perform one or more other operations described herein. [0041] In some aspects, a network node may include a communication manager 140 or a communication manager 150. As described in more detail elsewhere herein, the communication manager 140 or 150 may transmit a machine learning configuration associated with a machine learning component configured to generate, a predicted communication metric and a confidence indication, the machine learning component comprising a machine learning model configured to: obtain an input that comprises an input metric and an error measurement corresponding to the input metric; and provide and based at least in part on a machine learning function and the input, the predicted communication metric and the confidence indication; and transmit a reference signal. Additionally, or alternatively, the communication manager 140 or 150 may perform one or more other operations described herein.

[0042] As indicated above, Fig. 1 is provided as an example. Other examples may differ from what is described with regard to Fig. 1.

[0043] 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. The base station 110 may be equipped with a set of antennas 234a through 234t, such as T antennas (T> 1). The UE 120 may be equipped with a set of antennas 252a through 252r, such as R antennas (R > 1).

[0044] At the base station 110, a transmit processor 220 may receive data, from a data source 212, intended for the UE 120 (or a set of UEs 120). The transmit processor 220 may select one or more modulation and coding schemes (MCSs) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from that UE 120. The base station 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS(s) selected for the UE 120 and may provide data symbols for the UE 120. The transmit processor 220 may 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. The transmit processor 220 may 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 a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems), shown as modems 232a through 232t. For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem 232. Each modem 232 may use a respective modulator component to process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 may further use a respective modulator component to process (e.g., convert to analog, amplify, filter, and/or upconvert) the output sample stream to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas), shown as antennas 234a through 234t.

[0045] At the UE 120, a set of antennas 252 (shown as antennas 252a through 252r) may receive the downlink signals from the base station 110 and/or other base stations 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems), shown as modems 254a through 254r. For example, each received signal may be provided to a demodulator component (shown as DEMOD) of a modem 254. Each modem 254 may use a respective demodulator component to condition (e.g., filter, amplify, downconvert, and/or digitize) a received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modems 254, may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to a data sink 260, and may 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 CQI parameter, among other examples. In some examples, one or more components of the UE 120 may be included in a housing 284.

[0046] The network controller 130 may include a communication unit 294, a controller/processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0047] One or more 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, one or more antenna groups, one or more sets of antenna elements, and/or one or more 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 (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and/or one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components of Fig. 2.

[0048] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports that include RSRP, RSSI, RSRQ, and/or CQI) from the controller/processor 280. The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by the modems 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of the antenna(s) 252, the modem(s) 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, and/or the TX MIMO processor 266. The transceiver may be used by a processor (e.g., the controller/processor 280) and the memory 282 to perform aspects of any of the methods described herein (e.g., with reference to Figs. 4-10). [0049] At the base station 110, the uplink signals from UE 120 and/or other UEs may be received by the antennas 234, processed by the modem 232 (e.g., a demodulator component, shown as DEMOD, of the modem 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 the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and provide the decoded control information to the controller/processor 240. The base station 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and/or uplink communications.

The transceiver may include any combination of the antenna(s) 234, the modem(s) 232, the MIMO detector 236, the receive processor 238, the transmit processor 220, and/or the TX MIMO processor 230. The transceiver may be used by a processor (e.g., the controller/processor 240) and the memory 242 to perform aspects of any of the methods described herein (e.g., with reference to Figs. 4-10).

[0050] The controller/processor 240 of the base station 110, the controller/processor 280 of the UE 120, and/or any other component(s) of Fig. 2 may perform one or more techniques associated with machine learning for beam predictions with confidence indications, as described in more detail elsewhere herein.

The memory 242 and the memory 282 may store data and program codes for the base station 110 and the UE 120, respectively. In some examples, the memory 242 and/or the 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 700 of Fig. 7, process 800 of Fig. 8, and/or other processes as described herein.

[0051] In some aspects, a UE includes means for receiving a signal; means for determining, based at least in part on a machine learning component, a predicted communication metric and a confidence indication, the machine learning component comprising a machine learning model, and wherein determining the predicted communication metric and the confidence indication comprises: means for receiving, by the machine learning model, an input that comprises an input metric and an error measurement corresponding to the input metric; and/or means for providing, by the machine learning model, and based at least in part on a machine learning function and the input, the predicted communication metric and the confidence indication; and/or means for performing a wireless communication task based at least in part on the predicted communication metric and the confidence indication. The means for the UE to perform operations described herein may include, for example, one or more of communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller/processor 280, or memory 282.

[0052] In some aspects, a network node includes means for transmitting a machine learning configuration associated with a machine learning component configured to generate, a predicted communication metric and a confidence indication, the machine learning component comprising a machine learning model configured to: means for obtain, by the machine learning model, an input that comprises an input metric and an error measurement corresponding to the input metric; and/or means for provide, by the machine learning model, and based at least in part on a machine learning function and the input, the predicted communication metric and the confidence indication; and/or means for transmitting a reference signal.

In some aspects, the means for the network node to perform operations described herein may include, for example, one or more of communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller/processor 280, or memory 282.

[0053] 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 the controller/processor 280. [0054] As indicated above, Fig. 2 is provided as an example. Other examples may differ from what is described with regard to Fig. 2.

[0055] Fig. 3 is a diagram illustrating an example 300 of an O-RAN architecture, in accordance with the present disclosure. As shown in Fig. 3, the O-RAN architecture may include a control unit (CU) 310 that communicates with a core network 320 via a backhaul link. Furthermore, the CU 310 may communicate with one or more distributed units (DUs) 330 via respective midhaul links. The DUs 330 may each communicate with one or more radio units (RUs) 340 via respective fronthaul links, and the RUs 340 may each communicate with respective UEs 120 via radio frequency (RF) access links. The DUs 330 and the RUs 340 may also be referred to as O-RAN DUs (O-DUs) 330 and O-RAN RUs (O-RUs) 340, respectively. [0056] In some aspects, the DUs 330 and the RUs 340 may be implemented according to a functional split architecture in which functionality of a base station 110 (e.g., an eNB or a gNB) is provided by a DU 330 and one or more RUs 340 that communicate over a fronthaul link. Accordingly, as described herein, a base station 110 may include a DU 330 and one or more RUs 340 that may be co-located or geographically distributed. In some aspects, the DU 330 and the associated RU(s) 340 may communicate via a fronthaul link to exchange real-time control plane information via a lower layer split (LLS) control plane (LLS-C) interface, to exchange non-real-time management information via an LLS management plane (LLS-M) interface, and/or to exchange user plane information via an LLS user plane (LLS-U) interface.

[0057] Accordingly, the DU 330 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 340. For example, in some aspects, the DU 330 may host a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (e.g., forward error correction (FEC) encoding and decoding, scrambling, and/or modulation and demodulation) based at least in part on a lower layer functional split. Higher layer control functions, such as a packet data convergence protocol (PDCP), radio resource control (RRC), and/or service data adaptation protocol (SDAP), may be hosted by the CU 310. The RU(s) 340 controlled by a DU 330 may correspond to logical nodes that host RF processing functions and low-PHY layer functions (e.g., fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, and/or physical random access channel (PRACH) extraction and filtering) based at least in part on the lower layer functional split. Accordingly, in an O-RAN architecture, the RU(s) 340 handle all over the air (OTA) communication with a UE 120, and real-time and non-real-time aspects of control and user plane communication with the RU(s) 340 are controlled by the corresponding DU 330, which enables the DU(s) 330 and the CU 310 to be implemented in a cloud-based RAN architecture.

[0058] As indicated above, Fig. 3 is provided as an example. Other examples may differ from what is described with regard to Fig. 3.

[0059] Machine learning can be used in wireless communications to facilitate channel estimation, beam selection, beamforming, and/or other procedures in which predicted values can be useful. In some cases, for example, machine learning can be used for beam prediction. In beam prediction, a machine learning component implemented, for example, at a UE can be used to predict a channel metric (e.g., an RSRP) based on a machine learning model that is trained on empirical data (e.g., past values of the metric).

[0060] Machine learning based beam prediction can be subject to error. For example, given prior channel metric measurements, a future channel metric value is a random variable and is subject to randomness due to fading and noise, uncertainty of the UE’s future location, and/or error due to model limitations. In some cases, therefore, using a single predicted value from a machine learning model as a predictor may result in poor scheduling decisions, leading to scheduling conflicts, inadequate channels, and/or missed communications, thereby having a negative impact on network performance. [0061] Some aspects of the techniques and apparatuses described herein may provide a machine learning component that takes, as input, a measurement error, in addition to channel measurements, and provides, as output, a predicted value and a confidence indication associated with the predicted value. For example, in some aspects, a UE may receive a signal and determine, based at least in part on a machine learning component, a predicted communication metric and a confidence indication. In some aspects, the machine learning component may include a machine learning model. The UE may determine the predicted communication metric and the confidence indication based on receiving, by the machine learning model, an input that comprises an input metric and an error measurement corresponding to the input metric. The UE may provide, by the machine learning model, and based at least in part on a machine learning function and the input, the predicted communication metric and the confidence indication. In some aspects, the UE may perform a wireless communication task based at least in part on the predicted communication metric and the confidence indication.

[0062] In this way, some aspects may provide a more accurate machine learning component for beam prediction. For example, in some aspects, the machine learning component may provide a predicted mean communication metric and a standard deviation of the mean with respect to past measurements of the communication metric. In this manner, the standard deviation may provide a confidence level of the predicted mean values. The improved prediction facilitated by some aspects described may result in more efficient scheduling decisions and/or may result in higher quality communications, thereby positively impacting network performance.

[0063] Some aspects may include a machine learning model having certain characteristics. For example, to facilitate a standard deviation output, an output layer of the machine learning model may be configured so that the output is always positive. In some aspects, the past measurement pattern and measurement error quality may be used to facilitate determining the predicted standard deviation. In some aspects, the machine learning model also may be configured to receive sparse measurement patterns (e.g., where only a subset of beams are measured). Some aspects may facilitate more reliable beam prediction, proactive rejections of bad prediction, more accurate beam selection, less beam failure, and/or higher throughput among other examples.

[0064] Fig. 4 is a diagram illustrating an example 400 of machine learning for beam predictions with confidence indications, in accordance with the present disclosure. As shown in Fig. 4, a UE 402 and a network node 404 may communicate with one another.

[0065] As shown by reference number 406, the UE 402 may transmit, and the network node 404 may receive, a capability report that indicates a capability of the UE 402 to provide a confidence indication. In some aspects, the capability report may further indicate a supported activation type associated with an output layer of a machine learning model implemented at the UE 402.

[0066] As shown by reference number 408, the network node 404 may transmit, and the UE 402 may receive, a machine learning configuration associated with a machine learning component. In some aspects, the machine learning configuration may include a machine learning component 410 that includes a machine learning model 412, a set 414 of machine learning parameters, and/or activation indication associated therewith. As shown, the machine learning component 410 may be configured to generate a predicted communication metric, Y, and a confidence indication, C, using the machine learning model 412. The machine learning model 412 may take, as input, an input metric, X, and an error measurement, E _x , corresponding to the input metric X. The machine learning model 412 may be configured to use a machine learning function, F(X), to determine the predicted communication metric Y. For example, the machine learning model 412 may be configured to evaluate Y=F(X). In some aspects, the machine learning model 412 may be a neural network function.

[0067] In some aspects, the machine learning model may be identified by a machine learning model identifier (ID) such as, for example a neural network function (NNF) ID. In some aspects, each NNF supported by the machine learning component 410 may be identified by a standardized NNF ID. In some aspects, a non-standardized ID may be used to support NNF private extensions. In some aspects, the input metric X and the output metric Y may be standardized. In some aspects, the set 414 of machine learning parameters may be contextual. For example, the set 414 of machine learning parameters may be location and/or configuration specific.

[0068] As shown by reference number 416, the network node 404 may transmit, and the UE 402 may receive, a signal. The signal may include a reference signal such as, for example, a synchronization signal block (SSB), and/or a channel state information reference signal (CSI- RS), among other examples. As shown by reference number 418, the UE 402 may determine, based at least in part on the machine learning component 410, a predicted communication metric and a confidence indication. The machine learning component may include a machine learning model, and the UE 402 may determine the predicted communication metric and the confidence indication based on receiving, by the machine learning model, an input that comprises an input metric and an error measurement corresponding to the input metric; and providing, by the machine learning model, and based at least in part on a machine learning function and the input, the predicted communication metric and the confidence indication.

[0069] In some aspects, the input metric may include an RSRP, and the predicted communication metric may include a predicted RSRP. The confidence indication comprises a standard deviation associated with the predicted communication metric. In some aspects, the input metric may include an interpolated metric value. The UE 402 may determine a plurality of interpolated metric values that include the interpolated metric value and may select the interpolated metric value based at least in part on the error measurement comprising a smallest error measurement of a plurality of error measurements corresponding to the plurality of interpolated metric values.

[0070] As shown by reference number 420, the UE 402 may transmit, and the network node 404 may receive, a model error report that indicates a model inference error associated with the predicted communication metric. In some aspects, transmitting the model error report may include transmitting the model error report based at least in part on at least one analytic metric associated with the predicted communication metric satisfying a reporting condition. As shown by reference number 422, the UE 402 may transmit, and the network node 404 may receive, an output report. The output report may indicate at least one of the predicted communication metric or the confidence indication. In some aspects, the UE 402 may transmit the output report using an over-the-air communication. In some aspects, the output report may include a dedicated uplink control information (UCI) type in a physical layer beam report. In some aspects, the output report may be triggered based at least in part on a confidence indicator satisfying a reporting threshold. In some aspects, reporting a confidence indicator that satisfies a mitigation threshold may cause the network node 404 to trigger additional reference signal transmission and/or reporting in corresponding beam directions.

[0071] As indicated above, Fig. 4 is provided as an example. Other examples may differ from what is described with respect to Fig. 4.

[0072] Fig. 5 is a diagram illustrating an example 500 associated with machine learning for beam predictions with confidence indications, in accordance with the present disclosure. Example 500 illustrates a machine learning function 502. The machine learning function 502 may be implemented by the machine learning model 412 depicted in Fig. 4.

[0073] As shown, the machine learning function includes a first set 504 of input ports associated with a set of reference signals, a second set 506 of input ports associated with a set of error metrics, a first set 508 of output ports associated with a set of predicted communication metrics, and a second set 510 of output ports associated with a set of confidence measurement outputs. In some aspects, the machine learning function 502 may be configured to perform a pre-processing operation in which the machine learning function normalizing a set of input data based at least in part on a normalization metric.

[0074] In some aspects, for example, the machine learning component that implements the machine learning function 502 may obtain a set of measurements associated with a subset of the set of reference signals. The subset may include fewer reference signals than the set of reference signals, and the UE may obtain the set of measurements by skipping at least one configured measurement based at least in part on receiving a downlink communication during a measurement occasion corresponding to the configured measurement. In some aspects, the UE may generate a measurement pattern indication corresponding to the set of measurements, wherein the measurement pattern indication indicates at least one of an input port, of the set 504 of input ports, for which a measurement was not obtained, or an input port, of the set 504 of input ports, for which a measurement was obtained.

[0075] In some aspects, the UE may receive a configuration associated with a measurement input format corresponding to the measurement pattern indication. The UE may generate the measurement pattern indication based at least in part on the measurement input format. In some aspects, for example, the UE may generate an interpolated measurement corresponding to a port for which a measurement is not obtained, wherein the measurement pattern indication includes an indication of an interpolation error corresponding to the interpolated measurement.

[0076] For example, as shown in Fig. 5, each input port of the set 504 of input ports is labeled with an “AT’ to represent an input port for which a measurement was obtained or an “7” to represent an input port for which a measurement was not obtained (and, thus, for which an interpolation was generated). Corresponding error values may be provided via the set 506 of input ports. In some aspects, as shown, an error value may be set to “0” for those ports for which a measurement was obtained. In some aspects, rather than provide all of the interpolated measurements and corresponding errors to the machine learning function 502, a selection process may be performed by which one or more interpolations and corresponding errors are selected for providing to the machine learning function 502. For example, one or more interpolations with the smallest error values may be selected for providing to the machine learning function 502.

[0077] In some aspects, the UE may provide the predicted communication metric based on performing an autoregression procedure associated with the prior predicted communication metric. For example, in some aspects, there may be no beam measured. In this case, the UE, via the machine learning model, may perform time domain interpolation from previous beam measurements. In some aspects, a predicted communication metric from a prior step can be used as input to predict a communication metric in an next step using autoregression. The output standard deviation of a previous step can be provided as input as an error measure to the machine learning function 502. In some aspects, for example, the UE may determine multiple candidate inputs for the input of one beam. For example, the UE may identify a prior RSRP estimate from a previous long short term (LSTM) prediction and another prior estimate from spatial domain interpolation from a current step. In some aspects, the network may configure a rule for the UE to select which RSRP (or other communication metric) can be used as the input of the prediction. For example, in some aspects, the UE may select the input corresponding to the smaller interpolation and/or prediction error between the two candidates. [0078] As indicated above, Fig. 5 is provided as an example. Other examples may differ from what is described with respect to Fig. 5.

[0079] Fig. 6 is a diagram illustrating an example 600 associated with machine learning for beam predictions with confidence indications, in accordance with the present disclosure. Example 600 illustrates an output layer design. The output layer design may be implemented by the machine learning model 412 depicted in Fig. 4.

[0080] As shown, a first fully connected layer (FC 24* 12) may produce a first output having a first number of dimensions. A rectified linear unit (RELU) activation layer may receive the first output and produce a second output having the first number of dimensions. An LSTM layer may receive an output of the RELU activation layer and may provide an output to a second fully connected layer (FC 120*60) 602. A parallel output layer stack may include a fully connected layer (FC 120*60) 604. The LSTM layer may provide the output to both fully connected layers 602 and 604. The fully connected layer 602 may be connected to another RELU 606 and a final fully connected layer 608. The fully connected layer 604 may be connected to a RELU 610, another fully connected layer (FC 60*24) 612, and a shifted exponential linear unit (ELU) 614. While the fully connected layer 608 may be configured to output a mean communication metric, the shifted ELU layer 614 may be configured to output a standard deviation.

[0081] In some aspects, for example, the error measurement may include at least one prior confidence indication associated with the prior predicted communication metric. The UE may generate the predicted standard deviation based on an activation function. The activation function may be based at least in part on at least one of the shifted ELU or an optimal epsilon (eps) value. For example, the shifted ELU output may be given by ELU(x)+l+eps, where eps corresponds to a predefined small positive number. In some aspects, the activation function may be given by \X\+eps, X ^r 2 eps. or \X+eps\, among other examples. In some aspects, the output may be non-negative. For better convergence when applying certain loss function (e.g., the negative log likelihood function) during model training, the output of the standard deviation prediction layers may be configured to be positive in most cases. Alternatively, in some aspects, prior knowledge of the range of the standard deviation (e.g., the maximum standard deviation) may be used to facilitate producing a shifted and scaled version of a softmax, tanh function as the output layer. The scaling or shifting factor applied on the softmax or tanh function may be determined by the prior knowledge of the standard deviation range.

[0082] In some aspects, the activation function may be selected based on a balance between standard deviation prediction accuracy and training convergence rate. In some aspects, if an eps value is used, a small positive offset may be added to avoid a steep gradient region in the loss function. [0083] In some aspects, the UE may use dedicated hardware and/or software to run the machine learning model. In some aspects, the UE may support a customized output activation layer, as described above. In some other aspects, the UE may not support a customized output activation layer, as described above. In some aspects, for example, the UE may report the activation function type capability of the UE to the network node.

[0084] As indicated above, Fig. 6 is provided as an example. Other examples may differ from what is described with respect to Fig. 6.

[0085] Fig. 7 is a diagram illustrating an example process 700 performed, for example, by a UE, in accordance with the present disclosure. Example process 700 is an example where the UE (e.g., UE 402) performs operations associated with machine learning for beam predictions with confidence indicators.

[0086] As shown in Fig. 7, in some aspects, process 700 may include receiving a signal (block 710). For example, the UE (e.g., using communication manager 908 and/or reception component 902, depicted in Fig. 9) may receive a signal, as described above.

In some aspects, the at least one analytic metric comprises at least one of a mean deviation or a standard deviation. In some aspects, the analytic metric may be a likelihood. For example, the likelihood may be computed based on a predicted mean, a predicted standard deviation, and/or a measured value. In some aspects, the likelihood may be computed using a function configured by a network node (e.g., a network-configured function). [0092] In some aspects, process 700 includes receiving a machine learning configuration associated with the machine learning component. In some aspects, the machine learning function comprises a first set of input ports associated with a set of reference signals, a second set of input ports associated with a set of error metrics, wherein the set of error metrics includes the error measurement, a first set of output ports associated with a set of predicted communication metrics, wherein the set of predicted communication metrics includes the predicted communication metric, and a second set of output ports associated with a set of confidence measurement outputs, wherein the set of confidence measurement outputs includes the confidence indication. In a tenth aspect, alone or in combination with the ninth aspect, the set of reference signals comprises at least one of a synchronization signal block or a channel state information reference signal.

[0093] In some aspects, the first set of input ports is associated with at least one transmission configuration indication. In some aspects, the set of confidence measurement outputs comprises at least one of a standard deviation, a variance, a confidence range, or a failure probability. In some aspects, the set of error metrics comprises at least one of a time stamp, a measurement indication, an interpolation error, a measurement error, a prediction error, or an interference estimation.

[0094] In some aspects, process 700 includes performing a pre-processing operation corresponding to the set of reference signals.

In some aspects, the normalization metric comprises at least one of a mean deviation or a standard deviation. In some aspects, process 700 includes receiving an indication of the normalization metric.

[0096] In some aspects, obtaining the set of measurements comprises obtaining a first measurement using a first reception beam and obtaining a second measurement using a second reception beam. In some aspects, process 700 includes generating a measurement pattern indication corresponding to the set of measurements.
