DETAILED DESCRIPTION

The following detailed description refers to the accompanying drawings. The same reference numbers may be used in different drawings to identify the same or similar elements. In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular structures, architectures, interfaces, techniques, etc. in order to provide a thorough understanding of the various aspects of various embodiments.

In certain instances, descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the various embodiments with unnecessary detail. For the purposes of the present document, the phrases “A or B” and “A/B” mean (A), (B), or (A and B).

Sharing and Scaling Factors:

Aspects of the sharing factor between a serving cell and a cell with different physical cell identifiers (PCIs) for Layer 1 reference signal received power (Ll-RSRP) measurement may be defined in legacy third generation partnership project (3 GPP) specifications. However, some use cases may be problematic. Therefore, an alternative scaling factor design may be desirable for use with Ll-RSRP measurement. Embodiments herein relate to scaling factor design method for Ll- RSRP measurement for cells with different PCIs.

As used herein, the terms “sharing factor” and “scaling factor” may be used to describe various embodiments. Generally, sharing may be a concept that is due to the behavior of a SSB measurement, as described herein. If a SSB is overlapped, then the overlapped SSB may be used for a serving cell for some occasions, and another cell for other occasions. Then, scaling may be applied to the parameter P as described below. Generally, the two terms may be used interchangeably herein.

In legacy specifications, the scaling factor of P is used for Ll-RSRP measurement for a serving cell. Synchronization signal block (SSB) resources for Ll-RSRP measurement may collide with S SB-based measurement timing configuration (SMTC) and measurement gap, and so various scaling factors may be described for different colliding scenarios in section 9.5.4.1 of the 3GPP technical specification (TS).

In the 3GPP Release-17 (Rel-17) specifications, the scaling factor of P may be updated for Ll-RSRP measurement for both a serving cell and a cell with a different PCI because the SSB resource(s) between the serving cell and the cell with different a PCI (CDP) may collide with each other. At the same time, the SSB resource(s) from the two cells may collide with a SMTC and a measurement gap respectively (e.g., in one example the SSB resource from the serving cell may collide with a SMTC, and the SSB resource of the CDP may collide with a measurement gap). There are several scenarios for scaling factor design, which may increase the complexity of such design. Therefore, it may be desirable to design a unified method to calculate the scaling factor for different scenarios. Various terms may be used herein to describe various equations and calculations related to the scaling factor. As used herein, the following may be used:

- TSSB = ssb-periodicityServingCell, e.g., the SSB periodicity of the serving cell

- TsMTCpenod = the configured SMTC period

- TSSB CDP = SSB periodicity of the CDP

- Psc = sharing factor of serving cell when Ll-RSRP is only performed for serving cell

- PCDF = sharing factor of CDP when Ll-RSRP is only performed for CDP

- Pfinai, CDP = sharing factor of CDP when L 1 -RSRP is performed on both serving cell and cell with different PCI.

- Pfmai, sc = sharing factor of serving cell when Ll-RSRP is performed on both serving cell and CDP.

- xRP = periodicity of MG.

Further, with respect to concepts described in further detail below, Figure 1 depicts an example of the one element (e.g., SSB) being partially overlapped with another (e.g., an SMTC occasion). It will be understood that Figure 1 is intended as a very generalized and high level Figure for the sake of description of this concept. Specifically, Figure 1 shows three transmissions, Tx 105, Ty 110, and Tz 113. Tx 105 has a periodicity of 1, and Ty 110 and Tz both have a periodicity of 2. Each element 115 of the transmissions may or may not be transmitted in a transmission occasion 120. As can be seen in Figure 1, an element 115 of Tx 105 is transmitted in every occasion 120 (because it has a periodicity of 1), and an element 115 of Ty 110 is transmitted in every other occasion 120 (because it has a periodicity of 2). As such, it may be said that Tx 105 partially overlaps with Ty 110. Similarly, Tx 105 partially overlaps with Tz 113. It will be further noted that Ty 110 and Tz 113 are transmitted in separate transmission occasions 120, and so are said to be non-overlapping.

In embodiments, the scaling factor may be calculated based on the following two elements.

For the first element, the SSB resource for the serving cell and the SSB resource for the CDP may be compared with legacy scenarios to calculate Psc and PCDP respectively.

In one example, for frequency range 2 (“FR2,” which may describes frequencies between approximately 24.25 Gigahertz (GHz) and approximately 52.6 GHz), the Psc for a serving cell may be calculated based on:

Psc= - TSSB — > when the SSB of serving cell is partially overlapped with sMTCperiod measurement gap (TSSB <MGRP, where MGRP stands for the “measurement gap repetition period”) and SSB is partially overlapped with SMTC occasion (TSSB < TsMTCpenod) and SMTC occasion is partially or fully overlapped with a measurement gap (which may be referred to below as “MG” or “GAP”).

P = P sharing factor, when SSB of serving cell is not overlapped with measurement gap and SSB is fully overlapped with SMTC period (TSSB = TsMTCperiod).

Psc = — - — when SSB of serving cell is partially overlapped with GAP and SSB is partially overlapped with SMTC occasion (TSSB < TsMTCperiod) and SMTC occasion is not overlapped with GAP and

TsMTCperiod xRP Or

TsMTCperiod = xRP and TSSB < 0.5 *TsMTCperiod.

Psc is when SSB of serving cell is partially overlapped with GAP and

SSB is partially overlapped with SMTC occasion (TSSB < TsMTCperiod) and SMTC occasion is not overlapped with GAP and TsMTCperiod = xRP and TSSB = 0.5* TsMTCperiod p

Psc = - — when SSB of sterving cell is partially overlapped with GAP

(TSSB < xRP) and SSB is partially overlapped with SMTC occasion (TSSB < TsMTCperiod) and SMTC occasion is partially or fully overlapped with GAP.

In one example, for FR2, the PCDP for a CDP may be calculated based on:

1

- PCDP = - — — — — when SSB of cell with different PCI is not overlap 1 p 1 ed with measurement gap and SSB of cell with different PCI is partially overlapped with SMTC occasion (TSSB CDP < TsMTCperiod).

1

- PCDP = — — — — — — when SSB of cell with different PCI is partially overlapped with measurement gap and SSB of cell with different PCI is partially overlapped with SMTC occasion (TSSB CDP < TsMTCperiod) and SMTC occasion is not overlapped with measurement gap and

TsMTCperiod MGRP or TsMTCperiod = MGRP and TSSB CDP < 0.5 *TsMTCperiod

1

- PCDP = - — — — — when SSB of cell with different PCI is p 1 artially J overlapp ' ed with measurement gap (TSSB CDP <MGRP) and SSB of cell with different PCI is partially overlapped with SMTC occasion (TSSB CDP < TsMTCpenod) and SMTC occasion is partially or fully overlapped with measurement gap.

With the calculated Psc and PCDP, the new periodicity for serving cell and CDP may be derived as shown below:

T SSB_SC = Psc * TSSB_SC

The new periodicities have removed the impact of SMTC and measurement gap, and may be compared directly to get the final scaling factor for the serving cell and the CDP as follows:

Pfmai, SC = PSC

■ If TSSB_SC < TSSB_CDP :

Pfmai, CDP = PCDP

- If TSSB_CDP = TSSB_SC, the remaining part may be shared between serving cell and cell with different PCI as follows:

Pfmai, CDP = P C DP * 2

Pfmai, SC = Psc * 2

Ll -RSRP Measurement

For inter-cell transmission configuration indicator (TCI) indication, the target TCI may refer to a CDP. It is possible that synchronization signal block (SSB) configuration of the serving cell and the CDP are overlapped. It may be desirable to define Ll-RSRP measurement requirements for this case. Various embodiments in this section may provide measurement requirements for inter-cell beam indication where the SSB configuration for a serving cell and a CDP are overlapped.

In embodiments, SSBs associated with a CDP (e.g., a non-serving cell) may be used for neighbor cell Ll-RSRP measurement. The SSB configuration for a non-serving cell may be provided by a higher layer to the UE. The SSB configuration may be the same or different for a serving cell measurement and a non-serving cell measurement. The SSBs may be fully overlapped, partially overlapped, or non-overlapped.

For Frequency Range 1 (“FRl,” e.g. frequencies of less than approximately 6 GHz)

Both SSBs inside or outside of the SMTC may be used for both the serving cell and the non-serving cell (e.g., the CDP) for Ll-RSRP measurement. Because the beam received by the UE from both of these cells beam may be the same, the UE may be able to perform Ll-RSRP for both the serving cell and the non-serving cell simultaneously.

FR2

For FR2, there may be two cases for SSB overlapping:

Case 1: SSB for serving cell and non-serving cell are fully overlapped and different receive beams are used

Similar to a layer-3 (L3) measurement, for the intra-frequency case, the SSB configuration for the serving cell and the non-serving cell may be the same. Therefore, the SSB may be fully overlapped for the serving cell and the non-serving cell. In this case, inside of the SMTC, because the LI measurement may re-use the beam of the L3 measurement, the same receive beam may be used for both the serving cell and the non-serving cell. The UE may be able to perform Ll-RSRP measurement for both serving cell and non-serving cell simultaneously. For SSBs outside of the SMTC, different receive beams can be considered for the serving cell and the non-serving cell to find a more suitable beam. The SSB for the serving cell measurement and the SSB for the nonserving cell measurement may only be shared, e.g. some SSBs may be used for the serving cell and some others may be used for the non-serving cell. Ll-RSRP measurement may be performed in a sequential manner for the serving cell and the non-serving cell. Therefore, there may be a sharing factor for receive sweeping between the serving cell measurement and the non-serving cell measurement.

Case 2: SSB for serving cell and non-serving cell are partially overlapped and different RX beam is used

In this case, some SSBs used for the serving cell may not be overlapped with SSBs for a non-serving cell. For SSBs that are not overlapped with the serving cell, the UE may perform Ll- RSRP for the non-serving cell. For SSBs that are overlapped with the serving cell, a measurement restriction may be defined, e.g. UE is required to measure for the serving cell or the non-serving cell. It may not be required to perform measurement simultaneously for both the serving and the non-serving cells. A longer measurement period for SSB-based Ll-RSRP measurement may be expected.

In another embodiment, the SSB can still be shared when SSBs are overlapped. For example, when SSBs are overlapped, some SSBs may be used for the serving cell and some others may be used for the non-serving cell.

Case 3: SSB for serving cell and non-serving cell are fully or partially overlapped and the same receive beam is used

In this case, no matter whether the SSBs for the serving cell and the non-serving cell are fully or partially overlapped, the same receive beam may be used for the serving cell and the nonserving cell. Therefore, the UE may be able to measure the SSB for both cells simultaneously.

SYSTEMS AND IMPLEMENTATIONS

Figures 2-5 illustrate various systems, devices, and components that may implement aspects of disclosed embodiments.

Figure 2 illustrates a network 200 in accordance with various embodiments. The network 200 may operate in a manner consistent with 3GPP technical specifications for LTE or 5G/NR systems. However, the example embodiments are not limited in this regard and the described embodiments may apply to other networks that benefit from the principles described herein, such as future 3 GPP systems, or the like.

The network 200 may include a UE 202, which may include any mobile or non-mobile computing device designed to communicate with a RAN 204 via an over-the-air connection. The UE 202 may be communicatively coupled with the RAN 204 by a Uu interface. The UE 202 may be, but is not limited to, a smartphone, tablet computer, wearable computer device, desktop computer, laptop computer, in-vehicle infotainment, in-car entertainment device, instrument cluster, head-up display device, onboard diagnostic device, dashtop mobile equipment, mobile data terminal, electronic engine management system, electronic/engine control unit, electronic/engine control module, embedded system, sensor, microcontroller, control module, engine management system, networked appliance, machine-type communication device, M2M or D2D device, loT device, etc.

In some embodiments, the network 200 may include a plurality of UEs coupled directly with one another via a sidelink interface. The UEs may be M2M/D2D devices that communicate using physical sidelink channels such as, but not limited to, PSBCH, PSDCH, PSSCH, PSCCH, PSFCH, etc.

In some embodiments, the UE 202 may additionally communicate with an AP 206 via an over-the-air connection. The AP 206 may manage a WLAN connection, which may serve to offload some/all network traffic from the RAN 204. The connection between the UE 202 and the AP 206 may be consistent with any IEEE 802.11 protocol, wherein the AP 206 could be a wireless fidelity (Wi-Fi®) router. In some embodiments, the UE 202, RAN 204, and AP 206 may utilize cellular-WLAN aggregation (for example, LWA/LWIP). Cellular-WLAN aggregation may involve the UE 202 being configured by the RAN 204 to utilize both cellular radio resources and WLAN resources.

The RAN 204 may include one or more access nodes, for example, AN 208. AN 208 may terminate air-interface protocols for the UE 202 by providing access stratum protocols including RRC, PDCP, RLC, MAC, and LI protocols. In this manner, the AN 208 may enable data/voice connectivity between CN 220 and the UE 202. In some embodiments, the AN 208 may be implemented in a discrete device or as one or more software entities running on server computers as part of, for example, a virtual network, which may be referred to as a CRAN or virtual baseband unit pool. The AN 208 be referred to as a BS, gNB, RAN node, eNB, ng-eNB, NodeB, RSU, TRxP, TRP, etc. The AN 208 may be a macrocell base station or a low power base station for providing femtocells, picocells or other like cells having smaller coverage areas, smaller user capacity, or higher bandwidth compared to macrocells.

In embodiments in which the RAN 204 includes a plurality of ANs, they may be coupled with one another via an X2 interface (if the RAN 204 is an LTE RAN) or an Xn interface (if the RAN 204 is a 5G RAN). The X2/Xn interfaces, which may be separated into control/user plane interfaces in some embodiments, may allow the ANs to communicate information related to handovers, data/context transfers, mobility, load management, interference coordination, etc.

The ANs of the RAN 204 may each manage one or more cells, cell groups, component carriers, etc. to provide the UE 202 with an air interface for network access. The UE 202 may be simultaneously connected with a plurality of cells provided by the same or different ANs of the RAN 204. For example, the UE 202 and RAN 204 may use carrier aggregation to allow the UE 202 to connect with a plurality of component carriers, each corresponding to a Pcell or Scell. In dual connectivity scenarios, a first AN may be a master node that provides an MCG and a second AN may be secondary node that provides an SCG. The first/second ANs may be any combination of eNB, gNB, ng-eNB, etc.

The RAN 204 may provide the air interface over a licensed spectrum or an unlicensed spectrum. To operate in the unlicensed spectrum, the nodes may use LAA, eLAA, and/or feLAA mechanisms based on CA technology with PCells/Scells. Prior to accessing the unlicensed spectrum, the nodes may perform medium/carrier-sensing operations based on, for example, a listen-before-talk (LBT) protocol.

In V2X scenarios the UE 202 or AN 208 may be or act as a RSU, which may refer to any transportation infrastructure entity used for V2X communications. An RSU may be implemented in or by a suitable AN or a stationary (or relatively stationary) UE. An RSU implemented in or by: a UE may be referred to as a “UE-type RSU”; an eNB may be referred to as an “eNB-type RSU”; a gNB may be referred to as a “gNB-type RSU”; and the like. In one example, an RSU is a computing device coupled with radio frequency circuitry located on a roadside that provides connectivity support to passing vehicle UEs. The RSU may also include internal data storage circuitry to store intersection map geometry, traffic statistics, media, as well as applications/ software to sense and control ongoing vehicular and pedestrian traffic. The RSU may provide very low latency communications required for high speed events, such as crash avoidance, traffic warnings, and the like. Additionally or alternatively, the RSU may provide other cellular/WLAN communications services. The components of the RSU may be packaged in a weatherproof enclosure suitable for outdoor installation, and may include a network interface controller to provide a wired connection (e.g., Ethernet) to a traffic signal controller or a backhaul network.

In some embodiments, the RAN 204 may be an LTE RAN 210 with eNBs, for example, eNB 212. The LTE RAN 210 may provide an LTE air interface with the following characteristics: SCS of 15 kHz; CP-OFDM waveform for DL and SC-FDMA waveform for UL; turbo codes for data and TBCC for control; etc. The LTE air interface may rely on CSLRS for CSI acquisition and beam management; PDSCH/PDCCH DMRS for PDSCH/PDCCH demodulation; and CRS for cell search and initial acquisition, channel quality measurements, and channel estimation for coherent demodulation/detection at the UE. The LTE air interface may operating on sub-6 GHz bands.

In some embodiments, the RAN 204 may be an NG-RAN 214 with gNBs, for example, gNB 216, or ng-eNBs, for example, ng-eNB 218. The gNB 216 may connect with 5G-enabled UEs using a 5G NR interface. The gNB 216 may connect with a 5G core through an NG interface, which may include an N2 interface or an N3 interface. The ng-eNB 218 may also connect with the 5G core through an NG interface, but may connect with a UE via an LTE air interface. The gNB 216 and the ng-eNB 218 may connect with each other over an Xn interface.

In some embodiments, the NG interface may be split into two parts, an NG user plane (NG-U) interface, which carries traffic data between the nodes of the NG-RAN 214 and a UPF 248 (e.g., N3 interface), and an NG control plane (NG-C) interface, which is a signaling interface between the nodes of the NG-RAN214 and an AMF 244 (e.g., N2 interface).

The NG-RAN 214 may provide a 5G-NR air interface with the following characteristics: variable SCS; CP-OFDM for DL, CP-OFDM and DFT-s-OFDM for UL; polar, repetition, simplex, and Reed-Muller codes for control and LDPC for data. The 5G-NR air interface may rely on CSI-RS, PDSCH/PDCCH DMRS similar to the LTE air interface. The 5G-NR air interface may not use a CRS, but may use PBCH DMRS for PBCH demodulation; PTRS for phase tracking for PDSCH; and tracking reference signal for time tracking. The 5G-NR air interface may operating on FR1 bands that include sub-6 GHz bands or FR2 bands that include bands from 24.25 GHz to 52.6 GHz. The 5G-NR air interface may include an SSB that is an area of a downlink resource grid that includes PSS/SSS/PBCH.

In some embodiments, the 5G-NR air interface may utilize BWPs for various purposes. For example, BWP can be used for dynamic adaptation of the SCS. For example, the UE 202 can be configured with multiple BWPs where each BWP configuration has a different SCS. When a BWP change is indicated to the UE 202, the SCS of the transmission is changed as well. Another use case example of BWP is related to power saving. In particular, multiple BWPs can be configured for the UE 202 with different amount of frequency resources (for example, PRBs) to support data transmission under different traffic loading scenarios. A BWP containing a smaller number of PRBs can be used for data transmission with small traffic load while allowing power saving at the UE 202 and in some cases at the gNB 216. A BWP containing a larger number of PRBs can be used for scenarios with higher traffic load.

The RAN 204 is communicatively coupled to CN 220 that includes network elements to provide various functions to support data and telecommunications services to customers/subscribers (for example, users of UE 202). The components of the CN 220 may be implemented in one physical node or separate physical nodes. In some embodiments, NFV may be utilized to virtualize any or all of the functions provided by the network elements of the CN 220 onto physical compute/storage resources in servers, switches, etc. A logical instantiation of the CN 220 may be referred to as a network slice, and a logical instantiation of a portion of the CN 220 may be referred to as a network sub-slice.

In some embodiments, the CN 220 may be an LTE CN 222, which may also be referred to as an EPC. The LTE CN 222 may include MME 224, SGW 226, SGSN 228, HSS 230, PGW 232, and PCRF 234 coupled with one another over interfaces (or “reference points”) as shown. Functions of the elements of the LTE CN 222 may be briefly introduced as follows.

The MME 224 may implement mobility management functions to track a current location of the UE 202 to facilitate paging, bearer activation/deactivation, handovers, gateway selection, authentication, etc. The SGW 226 may terminate an SI interface toward the RAN and route data packets between the RAN and the LTE CN 222. The SGW 226 may be a local mobility anchor point for inter-RAN node handovers and also may provide an anchor for inter-3GPP mobility. Other responsibilities may include lawful intercept, charging, and some policy enforcement.

The SGSN 228 may track a location of the UE 202 and perform security functions and access control. In addition, the SGSN 228 may perform inter-EPC node signaling for mobility between different RAT networks; PDN and S-GW selection as specified by MME 224; MME selection for handovers; etc. The S3 reference point between the MME 224 and the SGSN 228 may enable user and bearer information exchange for inter-3 GPP access network mobility in idle/active states.

The HSS 230 may include a database for network users, including subscription-related information to support the network entities’ handling of communication sessions. The HSS 230 can provide support for routing/roaming, authentication, authorization, naming/addressing resolution, location dependencies, etc. An S6a reference point between the HSS 230 and the MME 224 may enable transfer of subscription and authentication data for authenticating/authorizing user access to the LTE CN 220.

The PGW 232 may terminate an SGi interface toward a data network (DN) 236 that may include an application/content server 238. The PGW 232 may route data packets between the LTE CN 222 and the data network 236. The PGW 232 may be coupled with the SGW 226 by an S5 reference point to facilitate user plane tunneling and tunnel management. The PGW 232 may further include a node for policy enforcement and charging data collection (for example, PCEF). Additionally, the SGi reference point between the PGW 232 and the data network 2 36 may be an operator external public, a private PDN, or an intra-operator packet data network, for example, for provision of IMS services. The PGW 232 may be coupled with a PCRF 234 via a Gx reference point.

The PCRF 234 is the policy and charging control element of the LTE CN 222. The PCRF 234 may be communicatively coupled to the app/content server 238 to determine appropriate QoS and charging parameters for service flows. The PCRF 232 may provision associated rules into a PCEF (via Gx reference point) with appropriate TFT and QCI.

In some embodiments, the CN 220 may be a 5GC 240. The 5GC 240 may include an AUSF 242, AMF 244, SMF 246, UPF 248, NSSF 250, NEF 252, NRF 254, PCF 256, UDM 258, and AF 260 coupled with one another over interfaces (or “reference points”) as shown. Functions of the elements of the 5GC 240 may be briefly introduced as follows.

The AUSF 242 may store data for authentication of UE 202 and handle authentication- related functionality. The AUSF 242 may facilitate a common authentication framework for various access types. In addition to communicating with other elements of the 5GC 240 over reference points as shown, the AUSF 242 may exhibit an Nausf service-based interface.

The AMF 244 may allow other functions of the 5GC 240 to communicate with the UE 202 and the RAN 204 and to subscribe to notifications about mobility events with respect to the UE 202. The AMF 244 may be responsible for registration management (for example, for registering UE 202), connection management, reachability management, mobility management, lawful interception of AMF-related events, and access authentication and authorization. The AMF 244 may provide transport for SM messages between the UE 202 and the SMF 246, and act as a transparent proxy for routing SM messages. AMF 244 may also provide transport for SMS messages between UE 202 and an SMSF. AMF 244 may interact with the AUSF 242 and the UE 202 to perform various security anchor and context management functions. Furthermore, AMF 244 may be a termination point of a RAN CP interface, which may include or be an N2 reference point between the RAN 204 and the AMF 244; and the AMF 244 may be a termination point of NAS (Nl) signaling, and perform NAS ciphering and integrity protection. AMF 244 may also support NAS signaling with the UE 202 over an N3 IWF interface.

The SMF 246 may be responsible for SM (for example, session establishment, tunnel management between UPF 248 and AN 208); UE IP address allocation and management (including optional authorization); selection and control of UP function; configuring traffic steering at UPF 248 to route traffic to proper destination; termination of interfaces toward policy control functions; controlling part of policy enforcement, charging, and QoS; lawful intercept (for SM events and interface to LI system); termination of SM parts of NAS messages; downlink data notification; initiating AN specific SM information, sent via AMF 244 over N2 to AN 208; and determining SSC mode of a session. SM may refer to management of a PDU session, and a PDU session or “session” may refer to a PDU connectivity service that provides or enables the exchange of PDUs between the UE 202 and the data network 236.

The UPF 248 may act as an anchor point for intra-RAT and inter-RAT mobility, an external PDU session point of interconnect to data network 236, and a branching point to support multi-homed PDU session. The UPF 248 may also perform packet routing and forwarding, perform packet inspection, enforce the user plane part of policy rules, lawfully intercept packets (UP collection), perform traffic usage reporting, perform QoS handling for a user plane (e.g., packet filtering, gating, UL/DL rate enforcement), perform uplink traffic verification (e.g., SDF- to-QoS flow mapping), transport level packet marking in the uplink and downlink, and perform downlink packet buffering and downlink data notification triggering. UPF 248 may include an uplink classifier to support routing traffic flows to a data network.

The NSSF 250 may select a set of network slice instances serving the UE 202. The NSSF 250 may also determine allowed NSSAI and the mapping to the subscribed S-NSSAIs, if needed. The NSSF 250 may also determine the AMF set to be used to serve the UE 202, or a list of candidate AMFs based on a suitable configuration and possibly by querying the NRF 254. The selection of a set of network slice instances for the UE 202 may be triggered by the AMF 244 with which the UE 202 is registered by interacting with the NSSF 250, which may lead to a change of AMF. The NSSF 250 may interact with the AMF 244 via an N22 reference point; and may communicate with another NSSF in a visited network via an N31 reference point (not shown). Additionally, the NSSF 250 may exhibit an Nnssf service-based interface.

The NEF 252 may securely expose services and capabilities provided by 3 GPP network functions for third party, internal exposure/re-exposure, AFs (e.g., AF 260), edge computing or fog computing systems, etc. In such embodiments, the NEF 252 may authenticate, authorize, or throttle the AFs. NEF 252 may also translate information exchanged with the AF 260 and information exchanged with internal network functions. For example, the NEF 252 may translate between an AF-Service-Identifier and an internal 5GC information. NEF 252 may also receive information from other NFs based on exposed capabilities of other NFs. This information may be stored at the NEF 252 as structured data, or at a data storage NF using standardized interfaces. The stored information can then be re-exposed by the NEF 252 to other NFs and AFs, or used for other purposes such as analytics. Additionally, the NEF 252 may exhibit an Nnef service-based interface.

The NRF 254 may support service discovery functions, receive NF discovery requests from NF instances, and provide the information of the discovered NF instances to the NF instances. NRF 254 also maintains information of available NF instances and their supported services. As used herein, the terms “instantiate,” “instantiation,” and the like may refer to the creation of an instance, and an “instance” may refer to a concrete occurrence of an object, which may occur, for example, during execution of program code. Additionally, the NRF 254 may exhibit the Nnrf service-based interface.

The PCF 256 may provide policy rules to control plane functions to enforce them, and may also support unified policy framework to govern network behavior. The PCF 256 may also implement a front end to access subscription information relevant for policy decisions in a UDR of the UDM 258. In addition to communicating with functions over reference points as shown, the PCF 256 exhibit an Npcf service-based interface.

The UDM 258 may handle subscription-related information to support the network entities’ handling of communication sessions, and may store subscription data of UE 202. For example, subscription data may be communicated via an N8 reference point between the UDM 258 and the AMF 244. The UDM 258 may include two parts, an application front end and a UDR. The UDR may store subscription data and policy data for the UDM 258 and the PCF 256, and/or structured data for exposure and application data (including PFDs for application detection, application request information for multiple UEs 202) for the NEF 252. The Nudr service-based interface may be exhibited by the UDR 221 to allow the UDM 258, PCF 256, and NEF 252 to access a particular set of the stored data, as well as to read, update (e.g., add, modify), delete, and subscribe to notification of relevant data changes in the UDR. The UDM may include a UDM- FE, which is in charge of processing credentials, location management, subscription management and so on. Several different front ends may serve the same user in different transactions. The UDM-FE accesses subscription information stored in the UDR and performs authentication credential processing, user identification handling, access authorization, registration/mobility management, and subscription management. In addition to communicating with other NFs over reference points as shown, the UDM 258 may exhibit the Nudm service-based interface.

The AF 260 may provide application influence on traffic routing, provide access to NEF, and interact with the policy framework for policy control.

In some embodiments, the 5GC 240 may enable edge computing by selecting operator/3 rd party services to be geographically close to a point that the UE 202 is attached to the network. This may reduce latency and load on the network. To provide edge-computing implementations, the 5GC 240 may select a UPF 248 close to the UE 202 and execute traffic steering from the UPF 248 to data network 236 via the N6 interface. This may be based on the UE subscription data, UE location, and information provided by the AF 260. In this way, the AF 260 may influence UPF (re)selection and traffic routing. Based on operator deployment, when AF 260 is considered to be a trusted entity, the network operator may permit AF 260 to interact directly with relevant NFs. Additionally, the AF 260 may exhibit an Naf service-based interface.

The data network 236 may represent various network operator services, Internet access, or third party services that may be provided by one or more servers including, for example, application/content server 238.

Figure 5 illustrates a network 500 in accordance with various embodiments. The network 500 may operate in a matter consistent with 3GPP technical specifications or technical reports for 6G systems. In some embodiments, the network 500 may operate concurrently with network 200. For example, in some embodiments, the network 500 may share one or more frequency or bandwidth resources with network 200. As one specific example, a UE (e.g., UE 502) may be configured to operate in both network 500 and network 200. Such configuration may be based on a UE including circuitry configured for communication with frequency and bandwidth resources of both networks 200 and 500. In general, several elements of network 500 may share one or more characteristics with elements of network 200. For the sake of brevity and clarity, such elements may not be repeated in the description of network 500.

The network 500 may include a UE 502, which may include any mobile or non-mobile computing device designed to communicate with a RAN 508 via an over-the-air connection. The UE 502 may be similar to, for example, UE 202.

Additionally, although not specifically shown in Figure 5, in some embodiments the RAN 508 may include one or more ANss such as AN 208 as described with respect to Figure 2. The RAN 508 and/or the AN of the RAN 508 may be referred to as a base station (BS), a RAN node, or using some other term or name.

The UE 502 and the RAN 508 may be configured to communicate via an air interface that may be referred to as a sixth generation (6G) air interface. The 6G air interface may include one or more features such as communication in a terahertz (THz) or sub-THz bandwidth, or joint communication and sensing. As used herein, the term “joint communication and sensing” may refer to a system that allows for wireless communication as well as radar-based sensing via various types of multiplexing. As used herein, THz or sub-THz bandwidths may refer to communication in the 80 GHz and above frequency ranges. Such frequency ranges may additionally or alternatively be referred to as “millimeter wave” or “mmWave” frequency ranges.

The RAN 508 may allow for communication between the UE 502 and a 6G core network (CN) 510. Specifically, the RAN 508 may facilitate the transmission and reception of data between the UE 502 and the 6G CN 510. The 6G CN 510 may include various functions such as NSSF 250, NEF 252, NRF 254, PCF 256, UDM 258, AF 260, SMF 246, and AUSF 242. The 6G CN 510 may additional include UPF 248 and DN 236 as shown in Figure 5.

Additionally, the RAN 508 may include various additional functions that are in addition to, or alternative to, functions of a legacy cellular network such as a 4G or 5G network. Two such functions may include a Compute Control Function (Comp CF) 524 and a Compute Service Function (Comp SF) 536. The Comp CF 524 and the Comp SF 536 may be parts or functions of the Computing Service Plane. Comp CF 524 may be a control plane function that provides functionalities such as management of the Comp SF 536, computing task context generation and management (e.g., create, read, modify, delete), interaction with the underlaying computing infrastructure for computing resource management, etc.. Comp SF 536 may be a user plane function that serves as the gateway to interface computing service users (such as UE 502) and computing nodes behind a Comp SF instance. Some functionalities of the Comp SF 536 may include: parse computing service data received from users to compute tasks executable by computing nodes; hold service mesh ingress gateway or service API gateway; service and charging policies enforcement; performance monitoring and telemetry collection, etc. In some embodiments, a Comp SF 536 instance may serve as the user plane gateway for a cluster of computing nodes. A Comp CF 524 instance may control one or more Comp SF 536 instances.

Two other such functions may include a Communication Control Function (Comm CF) 528 and a Communication Service Function (Comm SF) 538, which may be parts of the Communication Service Plane. The Comm CF 528 may be the control plane function for managing the Comm SF 538, communication sessions creation/configuration/releasing, and managing communication session context. The Comm SF 538 may be a user plane function for data transport. Comm CF 528 and Comm SF 538 may be considered as upgrades of SMF 246 and UPF 248, which were described with respect to a 5G system in Figure 2. The upgrades provided by the Comm CF 528 and the Comm SF 538 may enable service-aware transport. For legacy (e.g., 4G or 5G) data transport, SMF 246 and UPF 248 may still be used.

Two other such functions may include a Data Control Function (Data CF) 522 and Data Service Function (Data SF) 532 may be parts of the Data Service Plane. Data CF 522 may be a control plane function and provides functionalities such as Data SF 532 management, Data service creation/configuration/releasing, Data service context management, etc. Data SF 532 may be a user plane function and serve as the gateway between data service users (such as UE 502 and the various functions of the 6G CN 510) and data service endpoints behind the gateway. Specific functionalities may include include: parse data service user data and forward to corresponding data service endpoints, generate charging data, report data service status.

Another such function may be the Service Orchestration and Chaining Function (SOCF) 520, which may discover, orchestrate and chain up communi cation/computing/data services provided by functions in the network. Upon receiving service requests from users, SOCF 520 may interact with one or more of Comp CF 524, Comm CF 528, and Data CF 522 to identify Comp SF 536, Comm SF 538, and Data SF 532 instances, configure service resources, and generate the service chain, which could contain multiple Comp SF 536, Comm SF 538, and Data SF 532 instances and their associated computing endpoints. Workload processing and data movement may then be conducted within the generated service chain. The SOCF 520 may also responsible for maintaining, updating, and releasing a created service chain.

Another such function may be the service registration function (SRF) 514, which may act as a registry for system services provided in the user plane such as services provided by service endpoints behind Comp SF 536 and Data SF 532 gateways and services provided by the UE 502. The SRF 514 may be considered a counterpart of NRF 254, which may act as the registry for network functions.

Other such functions may include an evolved service communication proxy (eSCP) and service infrastructure control function (SICF) 526, which may provide service communication infrastructure for control plane services and user plane services. The eSCP may be related to the service communication proxy (SCP) of 5G with user plane service communication proxy capabilities being added. The eSCP is therefore expressed in two parts: eCSP-C 512 and eSCP-U 534, for control plane service communication proxy and user plane service communication proxy, respectively. The SICF 526 may control and configure eCSP instances in terms of service traffic routing policies, access rules, load balancing configurations, performance monitoring, etc.

Another such function is the AMF 544. The AMF 544 may be similar to 244, but with additional functionality. Specifically, the AMF 544 may include potential functional repartition, such as move the message forwarding functionality from the AMF 544 to the RAN 508.

Another such function is the service orchestration exposure function (SOEF) 518. The SOEF may be configured to expose service orchestration and chaining services to external users such as applications.

The UE 502 may include an additional function that is referred to as a computing client service function (comp CSF) 504. The comp CSF 504 may have both the control plane functionalities and user plane functionalities, and may interact with corresponding network side functions such as SOCF 520, Comp CF 524, Comp SF 536, Data CF 522, and/or Data SF 532 for service discovery, request/response, compute task workload exchange, etc. The Comp CSF 504 may also work with network side functions to decide on whether a computing task should be run on the UE 502, the RAN 508, and/or an element of the 6G CN 510.

The UE 502 and/or the Comp CSF 504 may include a service mesh proxy 506. The service mesh proxy 506 may act as a proxy for service-to- service communication in the user plane. Capabilities of the service mesh proxy 506 may include one or more of addressing, security, load balancing, etc. EXAMPLE PROCEDURES

The term “machine learning” or “ML” refers to the use of computer systems implementing algorithms and/or statistical models to perform specific task(s) without using explicit instructions, but instead relying on patterns and inferences. ML algorithms build or estimate mathematical model(s) (referred to as “ML models” or the like) based on sample data (referred to as “training data,” “model training information,” or the like) in order to make predictions or decisions without being explicitly programmed to perform such tasks. Generally, an ML algorithm is a computer program that learns from experience with respect to some task and some performance measure, and an ML model may be any object or data structure created after an ML algorithm is trained with one or more training datasets. After training, an ML model may be used to make predictions on new datasets. Although the term “ML algorithm” refers to different concepts than the term “ML model,” these terms as discussed herein may be used interchangeably for the purposes of the present disclosure.

The term “machine learning model,” “ML model,” or the like may also refer to ML methods and concepts used by an ML-assisted solution. An “ML-assisted solution” is a solution that addresses a specific use case using ML algorithms during operation. ML models include supervised learning (e.g., linear regression, k-nearest neighbor (KNN), descision tree algorithms, support machine vectors, Bayesian algorithm, ensemble algorithms, etc.) unsupervised learning (e.g., K-means clustering, principle component analysis (PCA), etc.), reinforcement learning (e.g., Q-learning, multi-armed bandit learning, deep RL, etc.), neural networks, and the like. Depending on the implementation a specific ML model could have many sub-models as components and the ML model may train all sub-models together. Separately trained ML models can also be chained together in an ML pipeline during inference. An “ML pipeline” is a set of functionalities, functions, or functional entities specific for an ML-assisted solution; an ML pipeline may include one or several data sources in a data pipeline, a model training pipeline, a model evaluation pipeline, and an actor. The “actor” is an entity that hosts an ML assisted solution using the output of the ML model inference). The term “ML training host” refers to an entity, such as a network function, that hosts the training of the model. The term “ML inference host” refers to an entity, such as a network function, that hosts model during inference mode (which includes both the model execution as well as any online learning if applicable). The ML-host informs the actor about the output of the ML algorithm, and the actor takes a decision for an action (an “action” is performed by an actor as a result of the output of an ML assisted solution). The term “model inference information” refers to information used as an input to the ML model for determining inference(s); the data used to train an ML model and the data used to determine inferences may overlap, however, “training data” and “inference data” refer to different concepts.
