These terms are only used to distinguish one element from another element. For example, a first element could also be termed as a second element, and similarly, a second element could also be termed as a first element, without departing from the scope of embodiments. As used herein, the term “and / or” includes any and all combinations of one or more of the listed terms.
[0056] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments. As used herein, the singular forms “a” , “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

The inference function is also responsible for data preparation (e.g., data pre-processing and cleaning, formatting, and transformation) based on inference data delivered by a data collection function, if required. - Inference output: data used by the management function to monitor the performance of AI / ML models or AI / ML functionalities. - Model storage: a function responsible for storing trained / updated models that can be used to perform the inference function.
[0058] In the context of the present disclosure, the term “AI / ML mobility” may be interchangeably used with “AI / ML based mobility” , “AI / ML for mobility” . The term “network functionality” may be interchangeably used with “NW-sided model” . The term “measurement configuration associated with RRM measurement prediction” means that the measurement configuration is for an input of a NW-sided model to perform RRM measurement prediction.
[0059] For convenience, some use cases for RRM measurement prediction for AI / ML mobility are listed below. Use cases 1 to 3 are considered for cell-level RRM measurement prediction. Use cases 4 to 6 are considered for beam-level RRM measurement prediction. - Use case 1 (UC1) : L1 beam-level measurement result (s) is predicted based on actual L1 beam-level measurement result (s) and then layer 3 (L3) cell-level measurement result is generated; - Use case 2 (UC2) : L3 cell-level measurement result (s) is predicted based on actual L3 cell-level measurement result (s) ; - Use case 3 (UC3) : L3 cell-level measurement result (s) is predicted based on actual L1 beam-level measurement result (s) ; - Use case 4 (UC4) : L1 filtered beam-level measurement result (s) is predicted based on actual L1 beam-level measurement result (s) and then L3 beam-level measurement result is generated; - Use case 5 (UC5) : L3 beam-level measurement result (s) is predicted based on actual L3 beam-level measurement result (s) ; - Use case 6 (UC6) : L3 beam-level measurement result (s) is predicted based on actual L1 beam-level measurement result (s) .
[0060] Currently, it is still unclear how NW distinghuishes L1 beam-level measurement results among L3 beam-level measurement results and L3 cell-level measurement results.
[0061] In view of this, the present disclosure provides a solution that supports a NW-sided model for AI / ML mobility. In the solution, a base station transmits, to a UE, a measurement configuration associated with RRM measurement prediction. The UE performs a measurement based on the measurement configuration, and transmits, to the base station, a measurement report comprising a result of the measurement for the RRM measurement prediction. With the solution, NW may distinguish received measurement results.
[0062] On the other hand, it is still unclear how to report data availability indication and available data if a UE is configured to log measurement results for usage of multiple use cases.
[0063] In view of this, the present disclosure provides another solution that supports a NW-sided model for AI / ML mobility. In the solution, a base station transmits, to a UE, a measurement configuration associated with data collection for use cases. Based on the measurement configuration, the UE performs a measurement and data logging in at least one buffer for the use cases. In accordance with a determination that the at least one buffer satisfies a condition, the UE transmits, to the base station, an indication of availability of data in the at least one buffer. With the solution, UE may report data availability if the UE is configured to log measurement results for the usage of multiple use cases.
[0064] Aspects of the present disclosure are described in the context of a wireless communications system.
[0065] Fig. 1 illustrates an example of a wireless communications system 100 that supports MAC layer security in accordance with aspects of the present disclosure. The wireless communications system 100 may include one or more network entities (also referred to as network equipment (NE) ) . For convenience, network entities 102-1, 102-2 and 102-3 are shown and are collectively referred to as one or more network entities 102 hereinafter. The wireless communications system 100 may further include one or more UEs 104, a core network 106, and a packet data network 108. The wireless communications system 100 may support various radio access technologies. In some implementations, the wireless communications system 100 may be a 4G network, such as an LTE network or an LTE-Advanced (LTE-A) network. In some other implementations, the wireless communications system 100 may be a 5G network, such as an NR network. In other implementations, the wireless communications system 100 may be a combination of a 4G network and a 5G network, or other suitable radio access technology including Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi) , IEEE 802.16 (WiMAX) , IEEE 802.20. The wireless communications system 100 may support radio access technologies beyond 5G, such as a 6G network. Additionally, the wireless communications system 100 may support technologies, such as time division multiple access (TDMA) , frequency division multiple access (FDMA) , or code division multiple access (CDMA) , etc.
[0066] The one or more network entities 102 may be dispersed throughout a geographic region to form the wireless communications system 100. One or more of the network entities 102 described herein may be or include or may be referred to as a network node, a base station, a network element, a radio access network (RAN) , a base transceiver station, an access point, a NodeB, an eNodeB (eNB) , a gNB, or other suitable terminology. A network entity 102 and a UE 104 may communicate via a communication link 110, which may be a wireless or wired connection. For example, a network entity 102 and a UE 104 may perform wireless communication (e.g., receive signaling, transmit signaling) over a Uu interface. The one or more network entities 102 may be collectively referred to as network entities 102 or individually referred to as a network entity 102.
[0067] A network entity 102 may provide one or more geographic coverage areas (also referred to as cells) for which the network entity 102 may support services (e.g., voice, video, packet data, messaging, broadcast, etc. ) for one or more UEs 104 within a geographic coverage area. For example, a network entity 102 and a UE 104 may support wireless communication of signals related to services (e.g., voice, video, packet data, messaging, broadcast, etc. ) according to one or multiple radio access technologies. In some implementations, a network entity 102 may be moveable, for example, a satellite associated with a non-terrestrial network. In some implementations, different geographic coverage areas associated with the same or different radio access technologies may overlap, but the different geographic coverage areas may be associated with different network entities 102. Information and signals described herein may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.
[0068] The one or more UEs 104 may be dispersed throughout a geographic region of the wireless communications system 100. A UE 104 may include or may be referred to as a mobile device, a wireless device, a remote device, a remote unit, a handheld device, or a subscriber device, or some other suitable terminology. In some implementations, the UE 104 may be referred to as a unit, a station, a terminal, or a client, among other examples. Additionally, or alternatively, the UE 104 may be referred to as an IoT device, an Internet-of-Everything (IoE) device, or machine-type communication (MTC) device, among other examples. In some implementations, a UE 104 may be stationary in the wireless communications system 100. In some other implementations, a UE 104 may be mobile in the wireless communications system 100.
[0069] The one or more UEs 104 may be devices in different forms or having different capabilities. Some examples of UEs 104 are illustrated in Fig. 1. A UE 104 may be capable of communicating with various types of devices, such as the network entities 102, other UEs 104, or network equipment (e.g., the core network 106, the packet data network 108, a relay device, an integrated access and backhaul (IAB) node, or another network equipment) , as shown in Fig. 1. Additionally, or alternatively, a UE 104 may support communication with other network entities 102 or UEs 104, which may act as relays in the wireless communications system 100.
[0070] A UE 104 may also be able to support wireless communication directly with other UEs 104 over a communication link 114. For example, a UE 104 may support wireless communication directly with another UE 104 over a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular-V2X deployments, the communication link 114 may be referred to as a sidelink. For example, a UE 104 may support wireless communication directly with another UE 104 over a PC5 interface.
[0071] A network entity 102 may support communications with the core network 106, or with another network entity 102, or both. For example, a network entity 102 may interface with the core network 106 through one or more backhaul links 116 (e.g., via an S1, N2, N2, or another network interface) . The network entities 102 may communicate with each other over the backhaul links 116 (e.g., via an X2, Xn, or another network interface) . In some implementations, the network entities 102 may communicate with each other directly (e.g., between the network entities 102) . In some other implementations, the network entities 102 may communicate with each other or indirectly (e.g., via the core network 106) . In some implementations, one or more network entities 102 may include subcomponents, such as an access network entity, which may be an example of an access node controller (ANC) . An ANC may communicate with the one or more UEs 104 through one or more other access network transmission entities, which may be referred to as a radio heads, smart radio heads, or transmission-reception points (TRPs) .
[0072] As an example, the network entity 102-1 may provide a cell 112-1 and the network entity 102-2 may provide a cell 112-2. It is to be understood that each of the network entities 102-1 and 102-2 may provide more cells (not shown) .
[0073] In an example, the network entity may be a satellite, for example, the network entity 102-3. The network entity 102-3 may have full or part of an eNB / gNB on board. The communication link 110 between the network entity 102-3 and the UE 104, the communication link 116 between the network entity 102-3 and the network entity 102-2, and the communication link 116 between the network entity 102-2 and the core network 106 may be used for an NTN transparent mode. The communication link 110 between the satellite 102-3 and the UE 104, and the communication link 116 between the network entity 102-3 (e.g., with a base station on board) and the core network 106 may be used for a NTN regenerative mode.
[0074] In some implementations, a network entity 102 may be configured in a disaggregated architecture, which may be configured to utilize a protocol stack physically or logically distributed among two or more network entities 102, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance) , or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN) ) . For example, a network entity 102 may include one or more of a central unit (CU) , a distributed unit (DU) , a radio unit (RU) , a RAN intelligent controller (RIC) (e.g., a near-real time RIC (Near-RT RIC) , a non-real time RIC (Non-RT RIC) ) , a service management and orchestration (SMO) system, or any combination thereof.
[0075] An RU may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a TRP. One or more components of the network entities 102 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 102 may be located in distributed locations (e.g., separate physical locations) . In some implementations, one or more network entities 102 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0076] Split of functionality between a CU, a DU, and an RU may be flexible and may support different functionalities depending upon which functions (e.g., network layer functions, protocol layer functions, baseband functions, radio frequency functions, and any combinations thereof) are performed at a CU, a DU, or an RU. For example, a functional split of a protocol stack may be employed between a CU and a DU such that the CU may support one or more layers of the protocol stack and the DU may support one or more different layers of the protocol stack. In some implementations, the CU may host upper protocol layer (e.g., L3, L2) functionality and signaling (e.g., RRC, service data adaption protocol (SDAP) , packet data convergence protocol (PDCP) ) . The CU may be connected to one or more DUs or RUs, and the one or more DUs or RUs may host lower protocol layers, such as a L1 (e.g., physical (PHY) layer) or an L2 (e.g., radio link control (RLC) layer, MAC) layer functionality and signaling, and may each be at least partially controlled by the CU 160.
[0077] Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU and an RU such that the DU may support one or more layers of the protocol stack and the RU may support one or more different layers of the protocol stack. The DU may support one or multiple different cells (e.g., via one or more RUs) . In some implementations, a functional split between a CU and a DU, or between a DU and an RU may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU, a DU, or an RU, while other functions of the protocol layer are performed by a different one of the CU, the DU, or the RU) .
[0078] A CU may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU may be connected to one or more DUs via a midhaul communication link (e.g., F1, F1-c, F1-u) , and a DU may be connected to one or more RUs via a fronthaul communication link (e.g., open fronthaul (FH) interface) . In some implementations, a midhaul communication link or a fronthaul communication link may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 102 that are in communication via such communication links.
[0079] The core network 106 may support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. The core network 106 may be an evolved packet core (EPC) , or a 5G core (5GC) , or a 6G core, which may include a control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , AMF) and a user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a packet data network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . In some implementations, the control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management (e.g., data bearers, signal bearers, etc. ) for the one or more UEs 104 served by the one or more network entities 102 associated with the core network 106.
[0080] The core network 106 may communicate with the packet data network 108 over one or more backhaul links 116 (e.g., via an S1, N2, N2, or another network interface) . The packet data network 108 may include an application server 118. In some implementations, one or more UEs 104 may communicate with the application server 118. A UE 104 may establish a session (e.g., a protocol data unit (PDU) session, or the like) with the core network 106 via a network entity 102. The core network 106 may route traffic (e.g., control information, data, and the like) between the UE 104 and the application server 118 using the established session (e.g., the established PDU session) . The PDU session may be an example of a logical connection between the UE 104 and the core network 106 (e.g., one or more network functions of the core network 106) .
[0081] In the wireless communications system 100, the network entities 102 and the UEs 104 may use resources of the wireless communications system 100 (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers) ) to perform various operations (e.g., wireless communications) . In some implementations, the network entities 102 and the UEs 104 may support different resource structures. For example, the network entities 102 and the UEs 104 may support different frame structures. In some implementations, such as in 4G, the network entities 102 and the UEs 104 may support a single frame structure. In some other implementations, such as in 5G and among other suitable radio access technologies, the network entities 102 and the UEs 104 may support various frame structures (i.e., multiple frame structures) . The network entities 102 and the UEs 104 may support various frame structures based on one or more numerologies.
[0082] One or more numerologies may be supported in the wireless communications system 100, and a numerology may include a subcarrier spacing and a cyclic prefix. A first numerology (e.g., μ=0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first numerology (e.g., μ=0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one slot per subframe. A second numerology (e.g., μ=1) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. A third numerology (e.g., μ=2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth numerology (e.g., μ=3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth numerology (e.g., μ=4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a normal cyclic prefix.
[0083] A time interval of a resource (e.g., a communication resource) may be organized according to frames (also referred to as radio frames) . Each frame may have a duration, for example, a 10 millisecond (ms) duration. In some implementations, each frame may include multiple subframes. For example, each frame may include 10 subframes, and each subframe may have a duration, for example, a 1 ms duration. In some implementations, each frame may have the same duration. In some implementations, each subframe of a frame may have the same duration.
[0084] Additionally or alternatively, a time interval of a resource (e.g., a communication resource) may be organized according to slots. For example, a subframe may include a number (e.g., quantity) of slots. The number of slots in each subframe may also depend on the one or more numerologies supported in the wireless communications system 100. For instance, the first, second, third, fourth, and fifth numerologies (i.e., μ=0, μ=1, μ=2, μ=3, μ=4) associated with respective subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz may utilize a single slot per subframe, two slots per subframe, four slots per subframe, eight slots per subframe, and 16 slots per subframe, respectively. Each slot may include a number (e.g., quantity) of symbols (e.g., orthogonal frequency division multiplexing (OFDM) symbols) . In some implementations, the number (e.g., quantity) of slots for a subframe may depend on a numerology. For a normal cyclic prefix, a slot may include 14 symbols. For an extended cyclic prefix (e.g., applicable for 60 kHz subcarrier spacing) , a slot may include 12 symbols. The relationship between the number of symbols per slot, the number of slots per subframe, and the number of slots per frame for a normal cyclic prefix and an extended cyclic prefix may depend on a numerology. It should be understood that reference to a first numerology (e.g., μ=0) associated with a first subcarrier spacing (e.g., 15 kHz) may be used interchangeably between subframes and slots.
[0085] In the wireless communications system 100, an electromagnetic (EM) spectrum may be split, based on frequency or wavelength, into various classes, frequency bands, frequency channels, etc. By way of example, the wireless communications system 100 may support one or multiple operating frequency bands, such as frequency range designations FR1 (410 MHz –7.125 GHz) , FR2 (24.25 GHz –52.6 GHz) , FR3 (7.125 GHz –24.25 GHz) , FR4 (52.6 GHz –114.25 GHz) , FR4a or FR4-1 (52.6 GHz –71 GHz) , and FR5 (114.25 GHz –300 GHz) . In some implementations, the network entities 102 and the UEs 104 may perform wireless communications over one or more of the operating frequency bands. In some implementations, FR1 may be used by the network entities 102 and the UEs 104, among other equipment or devices for cellular communications traffic (e.g., control information, data) . In some implementations, FR2 may be used by the network entities 102 and the UEs 104, among other equipment or devices for short-range, high data rate capabilities.
[0086] FR1 may be associated with one or multiple numerologies (e.g., at least three numerologies) . For example, FR1 may be associated with a first numerology (e.g., μ=0) , which includes 15 kHz subcarrier spacing; a second numerology (e.g., μ=1) , which includes 30 kHz subcarrier spacing; and a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing. FR2 may be associated with one or multiple numerologies (e.g., at least 2 numerologies) . For example, FR2 may be associated with a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing; and a fourth numerology (e.g., μ=3) , which includes 120 kHz subcarrier spacing.
[0087] It has been agreed that for network-side RRM measurement prediction, the legacy RRM measurement configuration and reporting framework can be reused for the RRM measurement prediction with NW-sided model. The measurement report of RRM measurement framework is L3-beam level results or L3-cell level, while for RRM measurement prediction with NW-sided model, the inference input may include L1-filtered beam-level measurement result (s) for use cases 1 and 3 (cell level) , and use cases 4 and 6 (beam level) .
[0088] It has been agreed that L1-filtered beam-level RSRP reporting can be configured by setting co-efficient to zero. Conventionally, the coefficient is configured in QuantityConfig IE. With the maxNrofQuantityConfig=2, L3-cell / L3-beam results can be obtained by setting the size=1, and L3-cell and L3-beam results can be obtained by setting the size=2. If NW only provides measurement reporting configuration (for AI / ML inference / prediction with NW-sided model) to UE and the measurement results include both L1-filtered beam level and L3-cell / beam level results, NW only knows whether the result is L3-beam level result (via rsIndexResults IE) or L3-cell level result (via cellResults IE) , and does not know whether the received measurement report is L1-beam level or not. Moreover, if the UE is configured to measure for AI / ML and legacy measurement simultaneously, NW does not know whether the received measurement result is for AI / ML or legacy measurement.
[0089] There may be three cases regarding the measurement configuration for AI / ML with L1-beam level as one of the measurement results, including: - Case#1: NW provides both the legacy measurement configuration and the measurement configuration for AI / ML to UE, and the measurement results of legacy measurement are L3-cell / beam level results while for measurement configuration for AI / ML, it is L1-filtered beam level results. - Case#2: NW only provides the measurement configuration for AI / ML to UE, and the measurement results include both L1-filtered beam level and L3-cell / beam level results. - Case#3: NW provides both the legacy measurement configuration and the measurement configuration for AI / ML to UE, and the measurement results of legacy measurement are L3-cell / beam level results while for AI / ML, it includes both L1-filtered beam level and L3-cell / beam level results.
[0090] NW needs to distinguish the L1-beam results among L3-cell and L3-beam for further regarding it as inference input for NW-sided model, e.g., Case#1, Case#2, and Case#3 in Table 1 below. Table 1
[0091] In view of this, the present disclosure provides a solution that supports a NW-sided model for AI / ML mobility. In the solution, a base station transmits, to a UE, a measurement configuration associated with RRM measurement prediction. The UE performs a measurement based on the measurement configuration, and transmits, to the base station, a measurement report comprising a result of the measurement for the RRM measurement prediction. With the solution, NW may distinguish received measurement results, e.g., at least for the above Cases #1 to #3.
[0092] On the other hand, UE configuration is provided via the RRM measurement framework. Granularity of an availability indication from UE is still unclear. Fig. 2 illustrates a diagram 200 illustrating example UE buffer cases in accordance with aspects of the present disclosure. As shown in FIG. 2, there may be two cases: UE buffer case#1 and UE buffer case#2. - UE buffer case#1: The buffer size for logging data is shared for all use cases. In this case, there is only one full buffer (e.g., Full) or one threshold or one percentage threshold (e.g., Thre) are configured for UE to trigger the logged data availability indication reporting. - UE buffer case#2: The access stratum (AS) layer memory for UE logging data is divided into several parts regarding to different use cases (e.g., UC1, UC2, UC3 and UC4) , and each part have its own full buffer (e.g., Full1, Full2, Full3, Full4) or buffer threshold or percentage threshold configuration (e.g., Thre1, Thre2, Thre3, Thre4) . These values of per use cases may be the same or different.
[0093] However, if the UE is configured to log measurement results for the usage of multiple use cases, some enhancements are needed to ensure UE reporting of the availability indication and UE reporting of the available data.
[0094] In view of this, the present disclosure provides another solution that supports a NW-sided model for AI / ML mobility. In the solution, a base station transmits, to a UE, a measurement configuration associated with data collection for use cases. Based on the measurement configuration, the UE performs a measurement and data logging in at least one buffer for the use cases. In accordance with a determination that the at least one buffer satisfies a condition, the UE transmits, to the base station, an indication of availability of data in the at least one buffer. With the solution, UE may report data availability if the UE is configured to log measurement results for the usage of multiple use cases.
[0095] Fig. 3 illustrates a signaling diagram illustrating an example process 300 that supports a NW-sided model for AI / ML mobility in accordance with aspects of the present disclosure. The process 300 may involve the UE 104 and the network entity 102. For the purpose of discussion, the process 300 will be described with reference to Fig. 1.
[0096] As shown in Fig. 3, at step 310, the network entity 102 may transmit, to the UE 104, a measurement configuration associated with RRM measurement prediction (also referred to as measurement configuration for AI / ML herein) .
[0097] In some implementations, the measurement configuration associated with RRM measurement prediction may comprise first information indicating that the measurement configuration is for the RRM measurement prediction or for AI / ML.
[0098] For example, the UE 104 may access the network entity 102 as a serving base station, e.g., gNB or 6G base station base station via a master cell group (MCG) only or dual connectivity (DC) . The network entity 102 may transmit a configuration related to the legacy measurement configuration and the measurement configuration associated with RRM measurement prediction to the UE 104 by means of a dedicated signaling, e.g., using the RRCReconfiguration or RRCResume. During providing the configuration, the network entity 104 may provide with an explicitly way to indicate the configuration is for RRM measurement prediction. That is, for the above Case#1, the measurement configuration associated with RRM measurement prediction may comprise the first information. It is to be noted that the present disclosure does not limit this aspect, and the first information may also be provided in the measurement configuration in any other suitable cases (e.g., Case#2, case#3, etc. ) .
[0099] In some implementations, the first information may be carried by a specific configuration for RRM measurement prediction. The network entity 102 may provide some specific configurations for measurement configuration for AI / ML, e.g., a measurement configuration ID (measID) , a measurement object ID (MeasObjectId) , a report configuration ID (ReportConfigId) , etc. For example, the first information may be carried by one or more of the measurement configuration ID, the measurement object ID, or the report configuration ID.
[0100] In some implementations, the first information may be carried by a report configuration (ReportConfig) IE. That is, the network entity 102 may provide an indication in the ReportConfig IE to indicate the configuration is for the RRM measurement prediction or for AI / ML.
[0101] In some implementations, the first information may be carried by a measurement object (MeasObject) IE. That is, the network entity 102 may provide an indication in the MeasObject IE to indicate the configuration is for the RRM measurement prediction or for AI / ML.
[0102] In some implementations, the first information may be carried by a measurement configuration ID (MeasID) IE. That is, the network entity 102 may provide an indication in the MeasID IE to indicate the configuration is for the RRM measurement prediction or for AI / ML.
[0103] In some implementations, the first information may be carried by a first IE in a quantity configuration (QuantityConfigNR IE) . The first IE indicates that the quantity configuration is for specifying one or more L1 filter configurations. In other words, the first IE may be introduced in the QuantityConfigNR IE, e.g., quantityConfigRS-L1-Index to indicate the quantity configuration is for specifying L1 filter configurations.
[0104] In some implementations, the first information may be carried by a mapping between the quantity configuration and a report configuration. That is, a mapping relationship may be introduced during providing the measurement configuration.
[0105] In some implementations, the mapping may be indicated by an ID associated with both the quantity configuration and the report configuration. For example, an IE may be introduced, e.g., QuantityReportId to identify the report configuration, i.e., linking of the quatity configuration and the report configuration.
[0106] In some implementations, the mapping is indicated by an indication of a value of the quantity configuration (QuantityConfig) in the ReportConfig IE. That is, an indication may be introduced to indicate the value of QuantityConfig in the ReportConfig IE.For example, indication=0 means QuantityConfig=0. It is to be noted that the indication may be set to be any other suitable values to indicate QuantityConfig=0.
[0107] In some implementations, the measurement configuration comprises second information indicating that the measurement configuration is for obtaining an L1 beam-level measurement result.
[0108] For example, the UE 104 may access the network entity 102 as a serving base station, e.g., gNB or 6G base station base station via a master cell group (MCG) only or dual connectivity (DC) . The network entity 102 may only provide the measurement configuration associated with RRM measurement prediction to the UE 104 by means of a dedicated signaling, e.g., using the RRCReconfiguration or RRCResume. This corresponds to Case#2. During providing the configuration, the network entity 104 may indicate the measurement configuration is for obtaining an L1 beam-level measurement result. That is, for the above Case#2, the measurement configuration associated with RRM measurement prediction may comprise the second information. It is to be noted that the present disclosure does not limit this aspect, and the second information may also be provided in the measurement configuration in any other suitable cases (e.g., Case#1, case#3, etc. ) .
[0109] In some implementations, the second information may be carried by a report configuration (ReportConfig) IE. That is, the network entity 102 may provide an indication in the ReportConfig IE to indicate the configuration is for obtaining the L1 beam-level measurement result.
[0110] In some implementations, the second information may be carried by a measurement object (MeasObject) IE. That is, the network entity 102 may provide an indication in the MeasObject IE to indicate the configuration is for obtaining the L1 beam-level measurement result.
[0111] In some implementations, the second information may be carried by a measurement configuration ID (MeasID) IE. That is, the network entity 102 may provide an indication in the MeasID IE to indicate the configuration is for obtaining the L1 beam-level measurement result.
[0112] In some implementations, the second information may be carried by the first IE in the QuantityConfigNR IE. Other details of the first IE are similar as that described for the first information, and thus are not repeated here for conciseness.
[0113] In some implementations, the second information may be carried by the mapping between the quantity configuration and the report configuration. Other details of the mapping are similar as that described for the first information, and thus are not repeated here for conciseness.
[0114] At step 320, the UE 104 may perform a measurement based on the measurement configuration.
[0115] At step 330, the UE 104 may transmit, to the network entity 102, a measurement report comprising a result of the measurement for the RRM measurement prediction.
[0116] In some implementations, based on the measurement configuration, the UE 104 may perform the measurement, and report the result of the measurement when a condition in the report configuration (ReportConfig) is satisfied. It is to be noted that the condition may be implemented in any suitable ways and the present disclosure does not limit the condition.
[0117] In some implementations, the measurement report may comprise third information indicating that the result of the measurement is an L1 beam-level measurement result. That is, the UE 104 may indicate in the measurement report that the result of the measurement is the L1 beam-level measurement result.
[0118] In some implementations, the third information may be carried by a measurement result IE (MeasResultsNR IE) . That is, an indication may be introduced to indicate that the result is L1-filtered beam level in the MearResultsNR IE.
[0119] In some implementations, the third information may be carried by a second IE in the measurement result IE. The second IE indicates that the result of the measurement is an L1 beam-level measurement result of a cell. For example, the UE 104 may provide an IE (e.g., rsIndexResults-L1) to indicate the L1-filtered beam level results of each cell in the MeasResultsNR IE, e.g., rsIndexResults-L1 includes L1 beam-level results based on SSB measurents (resultSSB-Indexes-L1) and L1 beam-level results based on CSI-RS measurents (resultCSI-RS-Indexes-L1) .
[0120] In some implementations, the third information may be carried by a third IE in the measurement result IE. The third IE indicates that the result of the measurement is an L1 beam-level measurement result of a cell of a beam. For example, the UE 104 may provide an IE to indicate the L1-filtered beam level results of each cell of each beam in rsIndexResults IE, e.g., resultSSB-Indexes-L1 and resultCSI-RS-Indexes-L1.
[0121] At step 340, the network entity 102 may receive the measurement result at a CU of the network entity 102 and transmit the measurement result to a DU of the network entity 102. For example, the CU may transmit the measurement result, e.g., L1 beam-level result, L3 cell-level result or L3 beam-level result, to the DU if the NW-sided model is attached in the DU.
[0122] With the process 300, some solutions are proposed for NW to distinguish the received measurement results by considering at least the Case#1, Case#2 and Case#3.
[0123] Fig. 4 illustrates a signaling diagram illustrating another example process 400 that supports a NW-sided model for AI / ML mobility in accordance with aspects of the present disclosure. The process 400 may involve the UE 104 and the network entity 102. For the purpose of discussion, the process 400 will be described with reference to Fig. 1.
[0124] As shown in Fig. 4, at step 410, the network entity 102 may transmit, to the UE 104, a measurement configuration (also referred to as data collection configuration herein) associated with data collection for use cases. It is to be noted that the use cases may be any two or more of the use cases 1 to 6 or any other use cases (e.g., non-AI use cases) .
[0125] In some implementations, the network entity 102 may provide a full buffer or buffer threshold per UE, and for each UE, there is only one full buffer or buffer threshold configuration. For example, the network entity 102 may configure a full buffer via a specific value of full buffer, e.g., 128KB. For example, the network entity 102 may configure a buffer threshold via a specific value of buffer threshold, e.g., Thre=1KB. For example, the network entity 102 may configure a percentage threshold of total UE buffer size, e.g., 90%.
[0126] In some implementations, the network entity 102 may configure a full buffer or buffer threshold for each use case. In some implementations, the measurement configuration may comprise an identity of a full buffer of each use case in the use cases. That is, the network entity 102 may configure a full buffer or buffer threshold for each use case via an identity of a full buffer of each use case in the use cases.
[0127] In some implementations, the measurement configuration may comprise a value of a first threshold for each use case. The first threshold is associated with a buffer size. That is, the network entity 102 may configure a full buffer or buffer threshold for each use case via a specific value of buffer threshold of each use case, e.g., Thre1=1 KB for use case#1, Thre2=2 KB for use case#2, etc.
[0128] In some implementations, the measurement configuration may comprise a value of a second threshold for each use case. The second threshold is associated with a percentage of the buffer size with respect to a total buffer size. That is, the network entity 102 may configure a full buffer or buffer threshold for each use case via a percentage threshold of total UE buffer size of each use case, e.g., P1=50%for use case#1, P2=30%for use case#2, etc.
[0129] At step 420, the UE 104 may perform, based on the measurement configuration, a measurement and data logging in at least one buffer for the use cases.
[0130] At step 430, upon determination that the at least one buffer satisfies a condition (also referred to as a first condition herein) , the UE 104 may transmit, to the network entity 102, an indication of availability of data in the at least one buffer.
[0131] In some implementations, the first condition may comprise a full buffer. That is, if a full buffer is satisfied, the UE 104 may transmit the indication of availability.
[0132] In some implementations, the first condition may comprise a threshold (also referred to as a buffer threshold herein) associated with a buffer size. That is, if a buffer threshold is satisfied, the UE 104 may transmit the indication of availability.
[0133] In some implementations, the first condition may comprise a threshold (also referred to as a percentage threshold herein) associated with a percentage of the buffer size with respect to a total buffer size. That is, if a percentage threshold is satisfied, the UE 104 may transmit the indication of availability.
[0134] In some implementations, the at least one buffer comprises a buffer for the use cases. For example, when the specific value of full buffer is reached, e.g., 128KB, or when the specific value of buffer threshold is reached, e.g., 1KB, or when the percentage of total UE buffer size is reached, e.g., 90%, the UE 104 may indicate the data availability to the network entity 102.
[0135] In some implementations, the at least one buffer comprises buffers for the use cases. In some implementations, if one of the buffers satisfies the condition, the UE 104 may transmit the indication of availability. For example, the UE 104 may transmit the indication of availablity if one of the full buffer or buffer threshold or percentage threshold per use case is satisfied, e.g., full buffer ID=1 for use case#1, or Thre=1 KB for use case#1, or P1=50%for use case#1, etc.
[0136] In some implementations where the at least one buffer comprises buffers for the use cases, if each of the buffers satisfies the condition, the UE 104 may transmit the indication of availability. For example, the UE 104 may transmit the indication of availablity if total full buffers or buffer threshold are satisfied.
[0137] In some implementations where the at least one buffer comprises buffers for the use cases, the UE 104 may transmit the indication of availability with first assistance information. In some implementations, the first assistance information may include fourth information indicating a use case for which the condition is satisfied. For example, the fourth information may indicate the full buffer or buffer threshold or percentage threshold of which use case is satisfied.
[0138] In some implementations, the fourth information may comprise an identity of the use case, i.e., the identity of each use case. Each use case may be identified by e.g., a use case ID, a configured ID for data logging, etc. In some implementations, the fourth information may comprise the value of the buffer threshold of the use case if multiple buffer thresholds are set to be different. In some implementations, the fourth information may comprise the value of the percentage threshold of the use case, i.e., the value of buffer threshold with the identity of each buffer threshold or percentage threshold if some / all buffer thresholds are the same, e.g., Thre1=Thre2=1 KB, while Thre1 with identity 1, and Thre2 with identity 2.
[0139] In some implementations, the first assistance information may include fifth information indicating available data of one or more use cases for which the condition is unsatisfied. In some implementations, the fifth information may comprise a percentage of the available data of a use case in the one or more use cases, e.g., 80%available data for use case#2, 50%available data for use case#3, etc. In some implementations, the fifth information may comprise a size of the available data of a use case in the one or more use cases. For example, an available data size for use case#2 is 10bits, an available data size for use case#3 is 16 bits, etc.
[0140] In some implementations, the UE 104 may re-transmit the indication of availability to the network entity 102. In some implementations, the UE 104 may re-transmit the available indication to the network entity 102 once a condition (also referred to as a second condition herein) is satisfied while does not receive an available data request from the network entity 102. In some implementations, the second condition may include that a time window expires. In some implementations, the second condition may include that a pre-defined maximum number of retransmissions is reached. In some implementations, the second condition may include that a total UE buffer size is full, etc. It is to be noted that any combinations of the above second conditions may also be feasible.
[0141] Continuing to refer to Fig. 4, at step 440, the network entity 102 may transmit a request for data to the UE 104. At step 450, upon reception of the request, the UE 104 may transmit the data (available data) to the network entity 102.
[0142] In some implementations where the at least one buffer comprises a buffer for the use cases, the UE 104 may transmit, to the network entity 102, the data with information (also referred to as second assistance information herein) indicating that the data is an L1 beam-level measurement result. That is, the UE 104 may report all available data with the second assistance information. Alternatively, the UE 104 may transmit, to the network entity 102, the data without the second assistance information.
[0143] In some implementations, the second assistance information may include the available data with data size, e.g., available data with size 8 bits indicates the data is L1-beam level results, etc. In some implementations, the second assistance information may include the available data with data indication, e.g., available data with 00 indicates the data is L1-beam level results, etc.
[0144] In some implementations where the at least one buffer comprises a buffer for the use cases, the UE 104 may transmit, to the network entity 102, a part of the data that is indicated in the request. In other words, the UE 104 may report available data based on an indication from the network entity 102. For example, after the network entity 102 receives the availability indication, the network entity 102 may send a request to the UE 104 to transmit the availability data with an indication of transmitting which type of data. When the UE 104 receives the request with the indication (e.g., the indication to transfer L1-beam level results) , then the UE 104 may transfer the data based on the indication.
[0145] In some implementations where the at least one buffer comprises a buffer for the use cases, the UE 104 may transmit, to the the network entity 102, a part of the data that is indicated in the measurement configuration. In other words, the UE 104 may report available data based on a configuration (e.g., DataCollectionConfigId) from the network entity 102. For example, the network entity 102 may request the UE 104 to transmit the availability data with the DataCollectionConfigId. After receiving the request, the UE 104 may send the available data corresponding to the DataCollectionConfigId.
[0146] In some implementations where the at least one buffer comprises a buffer for the use cases, the UE 104 may transmit, to the the network entity 102, a part of the data that is latest logged (i.e., latest logged data) . Alternatively, the UE 104 may transmit, to the network entity 102, a part of the data that has a highest priority (i.e., logged data with the highest priority) . As such, the UE 104 may only report a specific available data based on some rules.
[0147] In some implementations where the at least one buffer comprises buffers for the use cases, the UE 104 may report available data of a use case for which the second condition is satisfied. That is, the UE 104 may report available data of which use case based on whether the full buffer or buffer threshold or percentage threshold is satisfied. For example, the UE 104 may report available data only for a use case if only one full buffer or buffer threshold or percentage threshold is satisfied. For example, the UE 104 may report available data for all use cases if all full buffers or buffer thresholds or percentage threshold are satisfied.
[0148] In some implementations where the at least one buffer comprises buffers for the use cases, the UE 104 may report available data that is indicated in the request. That is, the UE reports the available data based on an indication from the network entity 102, e.g., use case ID, value of full buffer or buffer threshold or percentage threshold, etc.
[0149] In some implementations where the at least one buffer comprises buffers for the use cases, the UE 104 may report available data that is indicated in the measurement configuration. That is, the UE reports the available data based on a configuration from the network entity 102, e.g., DataCollectionConfigId.
[0150] In some implementations where the at least one buffer comprises buffers for the use cases, the UE 104 may report available data that is latest logged (i.e., the latest logged data) . Alternatively, the UE 104 may report available data that has the highest priority (i.e., the logged data with the highest priority) . Alernatively, the UE 104 may report the available data in which the full buffer or buffer threshold is satisfied upon receiving the request information from the network entity 102.
[0151] In some implementations where the at least one buffer comprises buffers for the use cases, the UE 104 may report available data of one or more use cases for which the condition is unsatisfied. For example, the UE 104 may report the available data in which the full buffer or buffer threshold is unsatisfied upon receiving the request information from the network entity 102.
[0152] With reference to Fig. 4, at step 460, the network entity 102 may transmit the received available data from the CU to a third party (e.g., Operations, Administration, and Maintenance (OAM) ) for performing the data collection, e.g., if the NW-sided model is attached in the third party.
[0153] With the process 400, some solutions are proposed for UE reporting the data availability if the UE is configured to log measurement results for the usage of multiple use cases by considering at least the UE buffer case#1 and UE buffer case#2.
[0154] It shall be noted that the steps and the order of the steps in any of the processes 300 and 400 are merely for illustration, and not for limitation. For example, the order of the steps may be changed. Some of the steps may be omitted or any other suitable additional steps may be added.
