Description

Technical Field

[0001] Various aspects of this disclosure relate to wireless communication, and more specifically to techniques for deactivating and reactivating reference signals (RS) used for data collection. Background Technology

[0002] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, broadcasting, or other similar services. These wireless communication systems may employ multiple access technologies that enable communication with several users by sharing available wireless communication system resources.

[0003] Despite significant technological advancements in wireless communication systems over the years, challenges remain. For example, complex and dynamic environments can still attenuate or block signals between wireless transmitters and receivers. Therefore, there is a continuous expectation for improving the technical performance of wireless communication systems, including, for example: improving communication speed and data carrying capacity; improving the efficiency of shared communication media; reducing the power used by transmitters and receivers during communication; improving the reliability of wireless communication; avoiding redundant transmission and / or reception and related processing; improving the coverage area of ​​wireless communication; increasing the number and types of devices that can access the wireless communication system; increasing the ability of different types of devices to communicate with each other; and increasing the number and types of available wireless communication media. Therefore, there is a need for further improvements to wireless communication systems to overcome the aforementioned technical challenges and other obstacles. Summary of the Invention

[0005] On the other hand, a method for wireless communication at a network entity is provided.

[0025] Various aspects of this disclosure provide apparatus, methods, processing systems, and computer-readable media for deactivating and reactivating a reference signal (RS) (e.g., for terminating and resuming data collection).

[0026] In some wireless systems, network entities (e.g., gNBs) can configure the UE for data collection operations. For example, a gNB can configure / activate a Channel State Information (CSI) Reference Signal (RS) for the UE to measure and report. In some cases, a gNB can configure / activate CSI-RS based on RS features requested by the UE.

[0027] However, in some cases, the UE may prefer to deactivate specific (e.g., periodic (P) / semi-persistent (SP)) CSI-RS resources. For example, in some situations, the UE may not have sufficient memory to handle data collection operations. This might be the case if the UE needs to upload locally collected data to another remote server for further model training, and the connection or communication bandwidth with the server is not functioning optimally. Handling active P / SP CSI-RS resource sets can consume unnecessary downlink overhead (e.g., and rate matching around such RSs can consume additional UE complexity / power), thus impacting system-level performance or UE end-to-end (E2E) performance. Furthermore, in some cases, once the UE is able (e.g., or willing) to further handle data collection operations, it may want to (re)activate / restore deactivated CSI-RS resource sets.

[0028] Various aspects of this disclosure provide mechanisms that allow a UE to request activation and / or deactivation of certain inactive and / or active (P / SP / Aperiodic (AP)) CSI-RS resources or sets of resources. For example, a UE may proactively request deactivation of certain currently active P / SP CSI-RS resources, or a UE may request activation / reinstatement of certain currently inactive SP / AP CSI-RS resources. In some cases, such requests may be delivered only for CSI-RS resources that have been indicated by the network as being specifically for data collection purposes and are not associated with scheduling downlink traffic (e.g., such CSI-RS resources may be within a pre-configured candidate group of the gNB).

[0029] The techniques disclosed herein can improve the speed of terminating or resuming UE-side data collection with minimal overhead and latency, which may have a positive impact on gNB system-level and / or UE E2E performance. An introduction to wireless communication networks

[0030] The techniques and methods described herein can be used in a variety of wireless communication networks. While aspects may be described herein using terms commonly associated with 3G, 4G, and / or 5G wireless technologies, aspects of this disclosure are equally applicable to other communication systems and standards not explicitly mentioned herein.

[0031] Figure 1 An example of a wireless communication network 100 in which the aspects described herein can be implemented is depicted.

[0032] Generally, wireless communication network 100 includes various network entities (optionally, network elements or network nodes). Network entities are typically communication devices and / or communication functions performed by communication devices (e.g., user equipment (UE), base station (BS), components of the BS, servers, etc.). For example, various functions of the network and various devices associated with and interacting with the network can be considered network entities. Furthermore, wireless communication network 100 includes terrestrial aspects, such as terrestrial network entities (e.g., BS 102), and non-terrestrial aspects, such as satellite 140 and aircraft 145, which may include onboard network entities (e.g., one or more BSs) capable of communicating with other network elements (e.g., terrestrial BSs) and user equipment.

[0033] In the depicted example, wireless communication network 100 includes BS 102, UE 104 and one or more core networks (such as Evolved Packet Core (EPC) 160 and 5G Core (5GC) network 190) that interoperate to provide communication services over various communication links, including wired and wireless links.

[0034] Figure 1 Various example UEs 104 are described, which may more generally include: cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, global positioning systems, multimedia devices, video devices, digital audio players, cameras, game consoles, tablet computers, smart devices, wearable devices, vehicles, electricity meters, air pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, Internet of Things (IoT) devices, always-on (AON) devices, edge processing devices, or other similar devices. UE 104 may also be more generally referred to as mobile devices, wireless devices, wireless communication devices, stations, mobile stations, subscriber stations, mobile subscriber stations, mobile units, subscriber units, wireless units, remote units, remote devices, access terminals, mobile terminals, wireless terminals, remote terminals, mobile phones, and others.

[0035] BS 102 communicates wirelessly with UE 104 via communication link 120 (e.g., transmitting or receiving signals to or from UE 104). Communication link 120 between BS 102 and UE 104 may include uplink (UL) (also known as reverse link) transmission from UE 104 to BS 102 and / or downlink (DL) (also known as forward link) transmission from BS 102 to UE 104. In various aspects, communication link 120 may utilize multiple-input multiple-output (MIMO) antenna technologies, including spatial multiplexing, beamforming, and / or transmit diversity.

[0036] BS 102 may typically include: NodeB, enhanced NodeB (eNB), next-generation enhanced NodeB (ng-eNB), next-generation NodeB (gNB or gNodeB), access point, transceiver base station, radio base station, radio transceiver, transceiver functionality, transmit / receive point, and / or others. Each BS in BS 102 may provide communication coverage for a corresponding geographic coverage area 110, which may sometimes be referred to as a cell, and in some cases may overlap (e.g., a small cell 102' may have a coverage area 110' that overlaps with the coverage area 110 of a macro cell). For example, BS may provide communication coverage for macro cells (covering a relatively large geographic area), pico cells (covering a relatively small geographic area, such as a stadium), femtocells (covering a relatively small geographic area (e.g., a home)), and / or other types of cells.

[0037] Although BS 102 is described as a single communication device in various aspects, it can be implemented in various configurations. For example, to give a few examples, one or more components of the base station can be decomposed, including a central unit (CU), one or more distributed units (DU), one or more radio units (RU), a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC. In another example, various aspects of the base station can be virtualized. More generally, a base station (e.g., BS 102) can include components located at a single physical location or components located at various physical locations. In examples where the base station includes components located at various physical locations, the various components can each perform functions, such that the various components collectively achieve functionality similar to a base station located at a single physical location. In some aspects, a base station including components located at various physical locations can be referred to as a decomposed radio access network architecture (such as an open RAN (O-RAN) or virtualized RAN (VRAN) architecture). Figure 2 An example decomposed base station architecture is depicted and described.

[0038] Different BSs 102 within the wireless communication network 100 can also be configured to support different radio access technologies (such as 3G, 4G, and / or 5G). For example, a BS 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with EPC 160 via a first backhaul link 132 (e.g., S1 interface). A BS 102 configured for 5G (e.g., 5G NR or Next Generation RAN (NG-RAN)) can interface with 5GC 190 via a second backhaul link 184. BSs 102 can communicate directly or indirectly (e.g., via EPC 160 or 5GC 190) on a third backhaul link 134 (e.g., X2 interface), which can be wired or wireless.

[0039] Wireless communication network 100 can subdivide the electromagnetic spectrum into various categories, bands, channels, or other characteristics. In some aspects, subdivision is provided based on wavelength and frequency, where frequency may also be referred to as carrier, subcarrier, channel, tone, or subband. For example, 3GPP currently defines frequency range 1 (FR1) as including 410 MHz to 7125 MHz, which is often (interchangeably) referred to as “below 6 GHz”. Similarly, 3GPP currently defines frequency range 2 (FR2) as including 24,250 MHz to 52,600 MHz, which is sometimes (interchangeably) referred to as “millimeter wave” (“mmW” or “mmWave”). Base stations configured to communicate using mmWave / near mmWave radio bands (e.g., mmWave base stations such as BS 180) can utilize beamforming (e.g., 182) with UEs (e.g., 104) to improve path loss and range.

[0040] The communication link 120 between BS 102 and, for example, UE 104 can be via one or more carriers, which may have different bandwidths (e.g., 5 MHz, 10 MHz, 15 MHz, 20 MHz, 100 MHz, 400 MHz and / or other MHz) and may be aggregated in various ways. The carriers may be adjacent to each other or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated to DL compared to UL).

[0041] Compared to lower-frequency communication, communication using higher frequency bands may have higher path loss and shorter range. Therefore, some base stations (e.g., Figure 1The beamforming 182 of the BS 180 (180) with the UE 104 can be used to improve path loss and range. For example, the BS 180 and UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays, to facilitate beamforming. In some cases, the BS 180 may transmit beamformed signals to the UE 104 in one or more transmit directions 182''. The UE 104 may receive beamformed signals from the BS 180 in one or more receive directions 182''. The UE 104 may also transmit beamformed signals to the BS 180 in one or more transmit directions 182''. The BS 180 may also receive beamformed signals from the UE 104 in one or more receive directions 182''. The BS 180 and UE 104 may then perform beamforming training to determine the optimal receive and transmit directions for each of the BS 180 and UE 104. It is worth noting that the transmit and receive directions of the BS 180 may be the same or different. Similarly, the sending and receiving directions of UE 104 can be the same or different.

[0042] The wireless communication network 100 further includes a Wi-Fi AP 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154 in, for example, unlicensed spectrum of 2.4 GHz and / or 5 GHz.

[0043] Some UEs 104 may use device-to-device (D2D) communication links 158 to communicate with each other. The D2D communication link 158 may use one or more sidelink channels, such as physical sidelink broadcast channel (PSBCH), physical sidelink discovery channel (PSDCH), physical sidelink shared channel (PSSCH), physical sidelink control channel (PSCCH), and / or physical sidelink feedback channel (PSFCH).

[0044] EPC 160 may include various functional components, including: Mobility Management Entity (MME) 162, other MMEs 164, Serving Gateway 166, Multimedia Broadcast Multicast Service (MBMS) Gateway 168, Broadcast Multicast Service Center (BM-SC) 170, and / or Packet Data Network (PDN) Gateway 172, as in the illustrated example. MME 162 may communicate with Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160. Generally, MME 162 provides bearer and connectivity management.

[0045] Generally, user Internet Protocol (IP) packets are transmitted through Serving Gateway 166, which is itself connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP services 176, which may include, for example, the Internet, intranets, IP Multimedia Subsystem (IMS), packet-switched (PS) streaming services, and / or other IP services.

[0046] The BM-SC 170 provides functionality for MBMS user service dispatch and delivery. The BM-SC 170 can serve as an entry point for content provider MBMS transmissions, can be used to authorize and initiate MBMS bearer services within a Public Land Mobile Network (PLMN), and / or can be used to schedule MBMS transmissions. The MBMS gateway 168 can be used to distribute MBMS services to BS 102 belonging to a Broadcast-Specific Service Single Frequency Network (MBSFN) area, and / or can be responsible for session management (start / stop) and collecting eMBMS-related billing information.

[0047] 5GC 190 may include various functional components, including: Access and Mobility Management Function (AMF) 192, other AMFs 193, Session Management Function (SMF) 194, and User Plane Function (UPF) 195. AMF 192 can communicate with Unified Data Management (UDM) 196.

[0048] AMF 192 is the control node that handles signaling between UE 104 and 5GC 190. AMF 192 provides services such as Quality of Service (QoS) flow and session management.

[0049] Internet Protocol (IP) packets are transmitted via UPF 195, which connects to IP service 197 and provides the UE with IP address allocation and other functions for 5GC 190. IP service 197 may include, for example, the Internet, intranet, IMS, PS streaming service, and / or other IP services.

[0050] In various aspects, to give a few examples, network entities or network nodes can be implemented as aggregated base stations, decomposed base stations, components of base stations, integrated access and backhaul (IAB) nodes, relay nodes, and sidelink nodes.

[0051] Figure 2An example decomposed base station 200 architecture is depicted. The decomposed base station 200 architecture may include one or more central units (CUs) 210, which may communicate directly with the core network 220 via a backhaul link, or indirectly with the core network 220 through one or more decomposed base station units, such as a near real-time (near-RT) RAN Intelligent Controller (RIC) 225 via an E2 link, or a non-real-time (non-RT) RIC 215 associated with a Service Management and Orchestration (SMO) framework 205, or both. CUs 210 may communicate with one or more distributed units (DUs) 230 via corresponding midhaul links (such as F1 interfaces). DUs 230 may communicate with one or more radio units (RUs) 240 via corresponding fronthaul links. RUs 240 may communicate with a corresponding UE 104 via one or more radio frequency (RF) access links. In some specific implementations, UE 104 may be served simultaneously by multiple RUs 240.

[0052] Each unit in a cell (e.g., CU 210, DU 230, RU 240, and near-RT RIC 225, non-RT RIC 215, and SMO frame 205) may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the cells, or an associated processor or controller that provides instructions to the cell's communication interface, may be configured to communicate with one or more other cells via the transmission medium. For example, these cells may include a wired interface configured to receive signals or transmit signals to one or more other cells via a wired transmission medium. Additionally or alternatively, a cell may include a wireless interface that may include a receiver, transmitter, or transceiver (such as a radio frequency (RF) transceiver) configured to receive signals on a wireless transmission medium or transmit signals to one or more other cells, or both.

[0053] In some aspects, CU 210 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP), Serving Data Adaptation Protocol (SDAP), etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by CU 210. CU 210 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP)), control plane functions (e.g., Central Unit-Control Plane (CU-CP)), or combinations thereof. In some implementations, CU 210 can be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, CU-UP units can communicate bidirectionally with CU-CP units via an interface such as an E1 interface. CU 210 can be implemented to communicate with DU 230 for network control and signaling, as needed.

[0054] DU 230 may correspond to a logic unit that includes one or more base station functions for controlling the operation of one or more RU 240s. In some aspects, DU 230 may host one or more of the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) at least in part, according to functional splits (such as those defined by the 3rd Generation Partnership Project (3GPP). In some aspects, DU 230 may also host one or more low PHY layers. Each layer (or module) may be implemented using an interface configured to communicate signaling with other layers (and modules) hosted by DU 230 or with control functions hosted by CU 210.

[0055] Lower-layer functionality can be implemented by one or more RU 240s. In some deployments, an RU240 controlled by a DU 230 may correspond to a logical node that hosts RF processing functions or low-PHY layer functions (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, Physical Random Access Channel (PRACH) extraction and filtering, or both, based at least in part on functional decomposition (such as lower-layer functional decomposition). In such architectures, the RU 240 may be implemented to handle over-the-air (OTA) communications with one or more UE 104s. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 240 may be controlled by the corresponding DU 230. In some scenarios, this configuration enables the implementation of the DU 230 and CU 210 in cloud-based RAN architectures (such as vRAN architectures).

[0056] SMO framework 205 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, SMO framework 205 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, SMO framework 205 can be configured to interact with a cloud computing platform such as Open Cloud (O-Cloud) 290 to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 210, DU 230, RU 240, and near-RT RIC 225. In some implementations, SMO framework 205 can communicate with hardware aspects of the 4G RAN, such as Open eNB (O-eNB) 211, via the O1 interface. Additionally, in some implementations, SMO framework 205 can communicate directly with one or more RU 240s via the O1 interface. SMO framework 205 may also include a non-RT RIC 215 configured to support the functionality of SMO framework 205.

[0057] The non-RT RIC 215 can be configured to include logical functions enabling non-real-time control and optimization of RAN elements and resources, including artificial intelligence / machine learning (AI / ML) workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 225. The non-RT RIC 215 can be coupled to or communicate with the near-RT RIC 225, such as via an A1 interface. The near-RT RIC 225 can be configured to include logical functions enabling near real-time control and optimization of RAN elements and resources via data collection and actions through an interface such as an E2 interface, connecting one or more CU 210s, one or more DU 230s, or both, and O-eNBs to the near-RT RIC 225.

[0058] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 225, the non-RT RIC 215 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 225 and may be received from non-network data sources or network functions at the SMO framework 205 or the non-RT RIC 215. In some examples, the non-RT RIC 215 or the near-RT RIC 225 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 215 may monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions via the SMO framework 205 (such as reconfiguration via O1) or by creating RAN management policies (such as A1 policies).

[0059] Figure 3 Various aspects of examples BS 102 and UE 104 are described.

[0060] Generally, BS 102 includes various processors (e.g., 320, 330, 338, and 340), antennas 334a to 334t (collectively referred to as 334), transceivers 332a to 332t (collectively referred to as 332) including modulators and demodulators, and other aspects that enable the wireless transmission of data (e.g., data source 312) and the wireless reception of data (e.g., data sink 339). For example, BS 102 can transmit and receive data between BS 102 and UE 104. BS 102 includes a controller / processor 340 that can be configured to implement the various functions described herein related to wireless communication.

[0061] Generally, UE 104 includes various processors (e.g., 358, 364, 366, and 380), antennas 352a to 352r (collectively referred to as 352), transceivers 354a to 354r (collectively referred to as 354) including modulators and demodulators, and other aspects that enable the wireless transmission of data (e.g., retrieved from data source 362) and the wireless reception of data (e.g., provided to data sink 360). UE 104 includes a controller / processor 380 that can be configured to implement the various functions described herein related to wireless communication.

[0062] Regarding example downlink transmission, BS 102 includes a transmission processor 320 that can receive data from data source 312 and control information from controller / processor 340. The control information may be for a Physical Broadcast Channel (PBCH), Physical Control Format Indicator Channel (PCFICH), Physical HARQ Indicator Channel (PHICH), Physical Downlink Control Channel (PDCCH), Group Shared PDCCH (GC PDCCH), and / or others. In some examples, this data may be for a Physical Downlink Shared Channel (PDSCH).

[0063] The transmitter processor 320 can process (e.g., encode and symbol map) data and control information to obtain data symbols and control symbols, respectively. The transmitter processor 320 can also generate reference symbols (such as those for the primary synchronization signal (PSS), secondary synchronization signal (SSS), PBCH demodulation reference signal (DMRS), and channel state information reference signal (CSI-RS)).

[0064] The transmit (TX) multiple-input multiple-output (MIMO) processor 330 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, and / or reference symbols where applicable, and can provide the output symbol stream to the modulators (MODs) in transceivers 332a to 332t. Each modulator in transceivers 332a to 332t can process its corresponding output symbol stream to obtain an output sample stream. Each modulator can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The downlink signal from the modulators in transceivers 332a to 332t can be transmitted via antennas 334a to 334t, respectively.

[0065] To receive downlink transmissions, UE 104 includes antennas 352a to 352r that receive downlink signals from BS 102 and provide the received signals to demodulators (DEMODs) in transceivers 354a to 354r, respectively. Each demodulator in transceivers 354a to 354r can adjust (e.g., filter, amplify, down-convert, and digitize) the corresponding received signal to obtain an input sample. Each demodulator can further process the input sample to obtain the received symbols.

[0066] The MIMO detector 356 can acquire received symbols from all demodulators in transceivers 354a to 354r, perform MIMO detection on the received symbols where applicable, and provide the detected symbols. The receive processor 358 can process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide the decoded data for UE 104 to data sink 360, and provide the decoded control information to controller / processor 380.

[0067] Regarding the example uplink transmission, UE 104 further includes a transmission processor 364 that receives and processes data from data source 362 (e.g., for PUSCH) and control information from controller / processor 380 (e.g., for Physical Uplink Control Channel (PUCCH)). Transmission processor 364 can also generate reference symbols for reference signals (e.g., for Sounding Reference Signal (SRS)). Symbols from transmission processor 364 may be pre-decoded by TX MIMO processor 366, where applicable, further processed by modulators in transceivers 354a to 354r (e.g., for SC-FDM), and transmitted to BS 102.

[0068] At BS 102, uplink signals from UE 104 can be received by antennas 334a to t, processed by demodulators in transceivers 332a to 332t, detected by MIMO detector 336 where applicable, and further processed by receiver processor 338 to obtain decoded data and control information transmitted by UE 104. Receiver processor 338 can provide the decoded data to data sink 339 and the decoded control information to controller / processor 340.

[0069] Memory 342 and memory 382 can store data and program code for BS 102 and UE 104, respectively.

[0070] Scheduler 344 can schedule UE to transmit data on the downlink and / or uplink.

[0071] In various respects, BS 102 can be described as transmitting and receiving various types of data associated with the methods described herein. In these contexts, “transmitting” can refer to various mechanisms that output data, such as from data source 312, scheduler 344, memory 342, transmit processor 320, controller / processor 340, TX MIMO processor 330, transceivers 332a to 332t, antennas 334a to 334t, and / or other aspects described herein. Similarly, “receiving” can refer to various mechanisms that acquire data, such as from antennas 334a to 334t, transceivers 332a to 332t, RX MIMO detector 336, controller / processor 340, receive processor 338, scheduler 344, memory 342, and / or other aspects described herein.

[0072] In various respects, UE 104 can also be described as transmitting and receiving various types of data associated with the methods described herein. In these contexts, “transmitting” can refer to various mechanisms that output data, such as from data source 362, memory 382, ​​transmit processor 364, controller / processor 380, TX MIMO processor 366, transceivers 354a to 354t, antennas 352a to 352t, and / or other aspects described herein. Similarly, “receiving” can refer to various mechanisms that acquire data, such as from antennas 352a to 352t, transceivers 354a to 354t, RX MIMO detector 356, controller / processor 380, receive processor 358, memory 382, ​​and / or other aspects described herein.

[0073] In some respects, the processor can be configured to perform various operations (such as those associated with the methods described herein) and to send (output) data to or receive data from another interface configured to send or receive data, respectively.

[0074] Figure 4A , Figure 4B , Figure 4C and Figure 4D Describes the use of wireless communication networks (such as Figure 1 All aspects of the data structure of the wireless communication network 100.

[0075] Specifically, Figure 4A Figure 400 is an example of the first subframe within a 5G (e.g., 5G NR) frame structure. Figure 4B Figure 430 illustrates an example of a DL channel within a 5G subframe. Figure 4C Figure 450 illustrates an example of the second subframe within a 5G frame structure, and Figure 4D Figure 480 illustrates an example of a UL channel within a 5G subframe.

[0076] Wireless communication systems can utilize Orthogonal Frequency Division Multiplexing (OFDM) with a cyclic prefix (CP) on both the uplink and downlink. Such systems can also support half-duplex operation using Time Division Duplex (TDD). OFDM and Single-Carrier Frequency Division Multiplexing (SC-FDM) will (e.g., as...) Figure 4B and Figure 4D The system bandwidth (as depicted in the text) is divided into multiple orthogonal subcarriers. Each subcarrier can be modulated with data. Modulation symbols can be transmitted in the frequency domain using OFDM and / or in the time domain using SC-FDM.

[0077] Wireless communication frame structures can be frequency division duplex (FDD), where for a specific set of subcarriers, subframes within that set are dedicated to either deep (DL) or ultra-low (UL). Wireless communication frame structures can also be time division duplex (TDD), where for a specific set of subcarriers, subframes within that set are dedicated to both DL and UL.

[0078] exist Figure 4A and Figure 4C In this example, the wireless communication frame structure is TDD, where D stands for DL, U for UL, and X is flexibly used between DL and UL. The UE can be configured using a time slot format (dynamically via DL control information (DCI) or semi-statically / statically via Radio Resource Control (RRC) signaling) through the received Time Slot Format Indicator (SFI). In the depicted example, a 10ms frame is divided into 10 equal-sized 1ms subframes. Each subframe may include one or more time slots. In some examples, each time slot may include 7 or 14 symbols, depending on the time slot format. Subframes may also include micro-slots, which typically have fewer symbols than the entire time slot. Other wireless communication technologies may have different frame structures and / or different channels.

[0079] In some respects, the number of time slots within a subframe is based on the time slot configuration and parameter set. For example, for time slot configuration 0, different parameter sets (μ) 0 to 5 allow for 1, 2, 4, 8, 16, and 32 time slots per subframe, respectively. For time slot configuration 1, different parameter sets 0 to 2 allow for 2, 4, and 8 time slots per subframe, respectively. Therefore, for time slot configuration 0 and parameter set μ, there are 14 symbols per time slot and 2µ time slots per subframe. The subcarrier spacing and symbol length / duration are functions of the parameter set. The subcarrier spacing can be equal to... kHz, where μ is the parameter set from 0 to 5. Therefore, the parameter set... It has a subcarrier spacing of 15 kHz and a parameter set It has a subcarrier spacing of 480 kHz. The symbol length / duration is negatively correlated with the subcarrier spacing. Figure 4A , Figure 4B , Figure 4C and Figure 4D It provides slot configuration 0 with 14 symbols per slot and parameter set with 4 slots per subframe. Example: The time slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs.

[0080] like Figure 4A , Figure 4B , Figure 4C and Figure 4DAs depicted, the resource grid can be used to represent the frame structure. Each time slot includes a resource block (RB) (also known as a physical RB (PRB)) extending for, for example, 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0081] like Figure 4A As illustrated in the example, some REs in the RE carry information for the UE (e.g., Figure 1 and Figure 3 The reference (pilot) signal (RS) for the UE (104) may include a demodulation RS (DMRS) and / or a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RS may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and / or a phase tracking RS (PT-RS).

[0082] Figure 4B Examples of various DL channels within a subframe of a frame are illustrated. The Physical Downlink Control Channel (PDCCH) carries the DCI within one or more Control Channel Elements (CCEs), each CCE comprising, for example, nine RE groups (REGs), each REG comprising, for example, four consecutive REs in an OFDM symbol.

[0083] The Primary Synchronization Signal (PSS) can be located within symbol 2 of a specific subframe of the frame. The PSS is generated by the UE (e.g., Figure 1 and Figure 3 104) is used to determine subframe / symbol timing and physical layer identifier.

[0084] The secondary synchronization signal (SSS) can be located in symbol 4 of a specific subframe of the frame. The SSS is used by the UE to determine the physical layer cell identifier group number and radio frame timing.

[0085] Based on the Physical Layer Identifier and Physical Layer Cell Identifier Group Number, the UE can determine the Physical Cell Identifier (PCI). Based on the PCI, the UE can determine the location of the aforementioned DMRS. The Physical Broadcast Channel (PBCH), carrying the Master Information Block (MIB), can be logically grouped with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block. The MIB provides the System Frame Number (SFN) and the number of Restricted Frames (RBs) in the system bandwidth. The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information (such as System Information Blocks (SIBs)) not transmitted via the PBCH, and / or paging messages.

[0086] like Figure 4CAs illustrated, some REs in the REs carry DMRS for channel estimation at the base station (indicated as R for a particular configuration, but other DMRS configurations are possible). The UE can transmit DMRS for PUCCH and DMRS for PUSCH. PUSCH DMRS can be transmitted, for example, in the first or second symbol before the PUSCH. PUCCH DMRS can be transmitted in different configurations depending on whether a short or long PUCCH is being transmitted and depending on the specific PUCCH format used. UE104 can transmit a Sounding Reference Signal (SRS). SRS can be transmitted, for example, in the last symbol of a subframe. SRS can have a comb structure, and the UE can transmit SRS on one of the comb teeth. SRS can be used by the base station for channel quality estimation to enable frequency-dependent scheduling of the UL.

[0087] Figure 4D Examples of various UL channels within a subframe of a frame are illustrated. The PUCCH can be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), pre-decoding matrix indicators (PMI), rank indicators (RI), and HARQ ACK / NACK feedback. The PUSCH carries data and may additionally be used to carry buffer status reports (BSR), power clearance reports (PHR), and / or UCI. Example framework for AI / ML in radio access networks

[0088] Figure 5 An example of an AI / ML functional framework 500 for RAN intelligence is depicted, in which the aspects described herein can be implemented.

[0089] The AI / ML functional framework includes data collection function 502, model training function 504, model inference function 506, and participant function 508. These functions interoperate to provide a platform for collaboratively applying AI / ML to various processes in RAN.

[0090] Data collection function 502 typically provides input data to model training function 504 and model inference function 506. AI / ML algorithm-specific data preparation (e.g., data preprocessing and cleaning, formatting and transformation) may not be performed in data collection function 502.

[0091] Examples of input data to data collection function 502 (or other functions) may include measurements from the UE or different network entities, feedback from participant functions, and outputs from AI / ML models. In some cases, data analysis required at model training function 504 and model inference function 506 may be performed at data collection function 502. As illustrated, data collection function 502 may deliver training data to model training function 504 and inference data to model inference function 506.

[0092] Model training function 504 can perform AI / ML model training, validation, and testing, which can generate model performance metrics as part of the model testing process. If needed, model training function 504 can also be responsible for data preparation (e.g., data preprocessing and cleaning, formatting, and transformation) based on the training data delivered by data collection function 502.

[0093] The model training function 504 can provide model deployment / update data to the model interface function 506. The model deployment / update data can be used to initially deploy the trained, validated, or tested AI / ML model to the model inference function 506 or to deliver the updated model to the model inference function 506.

[0094] As illustrated, model inference function 506 may provide AI / ML model inference output (e.g., prediction or decision) to participant function 508, and may sometimes provide model performance feedback to model training function 504. Model inference function 506 may also sometimes be responsible for data preparation (e.g., data preprocessing and cleaning, formatting and transformation) based on inference data delivered by data collection function 502.

[0095] The inference output of the AI / ML model can be generated by the model inference function 506. The specific details of this output can be specific in terms of use cases. Sometimes, model performance feedback can be used to monitor the performance of the AI / ML model. In some cases, for example, if certain information derived from the model inference function is applicable to improving the AI / ML model trained in the model training function 504, model performance feedback can be delivered to the model training function 504.

[0096] Model inference function 506 can signal the model's output to nodes that have requested the model's output (e.g., via subscription) or to nodes that take action based on the output from the model inference function. Before deployment, the AI / ML model used in model inference function 506 may need to be initially trained, validated, and tested by model training function. Model training function 504 and model inference function 506 may be able to request specific information that will be used to train or execute AI / ML algorithms and avoid receiving unnecessary information. The nature of such information can depend on the use case and the AI / ML algorithm.

[0097] Participant function 508 can receive output from model inference function 506, which can trigger or execute corresponding actions. Participant function 508 can trigger actions against other entities or against itself. Feedback generated by participant function 508 can provide information for deriving training data, inference data, or for monitoring the performance of AI / ML models. As noted above, input data for data collection function 502 may include this feedback from participant function 508. Feedback from automatic author function 508 or other network entities (via data collection functions) can also be used at model inference function 506.

[0098] The AI / ML functional framework 500 can be deployed in a variety of RAN intelligence-based use cases. Such use cases can include CSI feedback enhancement, enhanced beam management (BM), positioning and location (Pos-Loc) accuracy enhancement, and a variety of other use cases. Overview of Model Training in Radio Access Networks

[0099] In 5G NR, depending on the ML use case, the data collection process can be performed on the UE side (e.g., by measuring some reference signals), on the gNB side, or through collaboration between the gNB and the UE. Similarly, ML model training and usage for prediction or inference can be performed at the same or different locations.

[0100] For example, for in Figure 6 and Figure 7 The network energy-saving use case illustrated in the example allows training and inference to be performed at a Next Generation Radio Access Network (NG-RAN) node or an OAM node while one or more UEs are performing data collection.

[0101] Figure 6 An example call flowchart 600 is illustrated, in which model training is performed at the OAM node 606, and model inference is performed at the NG-RAN node (such as NG-RAN node 1 602 or NG-RAN node 2 604 as illustrated). As illustrated, in this example, one or more UEs 104 participate in data collection based on measurement reports. In this use case, the UEs and NG-RAN nodes can perform one or more network energy-saving actions based on ML model inference.

[0102] Figure 7 Another example call flow diagram 700 is illustrated, in which both model training and model inference are performed at the NG-RAN node while one or more UEs are involved in data collection. Again, in this use case, the UE and the NG-RAN node can perform one or more network energy-saving actions.

[0103] Generally, data collected at different UEs can later be shared with the network (e.g., gNB) to train a global model that explains different environmental conditions. Even multiple gNBs and other core network (CN) entities can exchange data / model updates to train robust ML models that work in different settings. Furthermore, in 5G NR, joint learning can be applied, where UEs can train their local models and share model updates with gNBs. Various aspects related to RS deactivation and reactivation

[0104] Various aspects of this disclosure provide apparatus, methods, processing systems, and computer-readable media for deactivating and reactivating a reference signal (RS) (e.g., for terminating and resuming data collection).

[0105] As noted above, network entities (e.g., gNBs) can configure UEs for data collection operations. In some cases, certain RSs can be configured as auxiliary, meaning that such RSs can be used for purposes other than enhancing UE communications for performing measurements and reporting. For example, measurements and reporting may be performed for data collection purposes, to train ML models, to enhance network operations by allowing visibility of observations from multiple UEs, or for other purposes.

[0106] Figure 8 Example 800 of an auxiliary reference signal is depicted, which may vary in frequency and spatial resources (e.g., transmitted using different beams).

[0107] Example 800 illustrates a beam prediction target 802 for a beam prediction process, which may be reference signal resources (e.g., 8 narrow beams every 5 milliseconds) in multiple target beam directions. The UE can predict beams within the beam prediction target 802 based on measurements of other RS ​​resources. For example, the UE can measure / predict the performance of some or all of the beam prediction targets in the beam prediction target 802 by measuring (e.g., L1-RSRP measurements) the auxiliary reference signals received in the beams within the beam prediction target 802.

[0108] Example 800 illustrates a first set of auxiliary reference signals 804 in a reference signal resource, which is a subset of beam prediction targets 802 and is present in each other beam prediction target in a beam scan. Beam scanning of the auxiliary signals may occur according to a first periodicity. The next beam scan may use beam prediction targets not used in the previous beam scan timing.

[0109] Example 800 also illustrates a second set of auxiliary reference signals 806 transmitted in the reference signal resources of all beam prediction targets in beam prediction target 802. Beam scanning may occur according to a second periodicity, which is longer than the first periodicity in Example 800.

[0110] In some aspects, the UE may recommend a set of reference signal resources for the auxiliary reference signal. This recommendation may indicate specific reference signal resources (e.g., which beam prediction targets). The recommendation may also indicate parameters associated with the set of reference signal resources, such as the number of reference signals in the set, the periodicity of the reference signal resources, the type of reference signal resources, the frequency domain density of the reference signal resources (e.g., the number of resource elements per PRB in the BWP or the PRB density), and / or the spatial association between the beam prediction target 802 and the auxiliary reference signal. The spatial association may be based at least in part on the number of beam prediction targets with the maximum signal strength, such as the number of reference signals in the set, the number of reference signals in the BWP, the number of reference signals in the BWP, the number of reference signals in the BWP, the number of reference signals in the BWP, the number of reference signals in the BWP, and / or the spatial association between the beam prediction target 802 and the auxiliary reference signal. K Each beam. The recommendation may also indicate frequency domain density, such as RE and / or PRB density per PRB in the BWP (e.g., PRB per band specifying a size).

[0111] However, as noted above, in some cases, the UE may prefer to deactivate certain (e.g., periodic (P) / semi-persistent (SP)) CSI-RS resources. For example, in some cases, the UE may not have sufficient memory to handle data collection operations (e.g., because it needs to upload locally collected data to another remote server for further model training, and the connection or communication bandwidth with the server is not functioning optimally). Furthermore, handling active P / SP CSI-RS resource sets may consume unnecessary downlink overhead (e.g., and rate matching around such RSs may consume additional UE complexity / power), thus impacting system-level performance or UE end-to-end (E2E) performance. In some cases, once the UE is able (e.g., or willing) to further handle data collection operations, it may want to (re)activate / restore deactivated CSI-RS resource sets.

[0112] Various aspects of this disclosure provide mechanisms that allow a UE to request activation and / or deactivation of certain inactive and / or active (P / SP / Aperiodic (AP)) CSI-RS resources or sets of resources. For example, a UE may proactively request deactivation of certain currently active P / SP CSI-RS resources, or a UE may request activation / reinstatement of certain currently inactive SP / AP CSI-RS resources. In some cases, such requests may be delivered only for CSI-RS resources that have been indicated by the network as being specifically for data collection purposes and are not associated with scheduling downlink traffic (e.g., such CSI-RS resources may be within a pre-configured candidate group of the gNB).

[0113] Figure 9 An example call flowchart 900 is depicted according to certain aspects of this disclosure.

[0114] As illustrated in 905, a network entity may send a configuration indicating an RS resource (e.g., a secondary RS resource). As illustrated in 906, the network entity may then (on the RS resource, according to the indicated configuration) send one or more RSs using various beams.

[0115] As illustrated at 910, a UE may send a request to disable one or more RS resources (e.g., those associated with certain beams). For example, as shown at 908 (where fewer RS ​​resources are sent), a network entity may disable one or more RS resources / beams based on a request, and may send RS resources and beams that are not disabled based on the request. In some cases, the request may be transmitted based on some type of condition (e.g., related to available processing resources or power at the UE).

[0116] As illustrated at 915, a UE may send a request to activate one or more RS resources (e.g., associated with certain beams). For example, as shown at 906, a network entity may activate one or more RS resources / beams based on the request, and may transmit RS on RS resources and beams including those RS resources and beams activated based on the request.

[0117] Figure 10 Figure 1000 illustrates a deactivation request according to certain aspects of this disclosure.

[0118] As illustrated at 1005, the UE may have previously been configured / activated with one or more (currently active) CSI-RS and / or CSI interference measurements (IM) for UE-side data collection.

[0119] As illustrated at 1010, the UE may decide that it does not prefer (e.g., cannot or is unwilling) receiving / processing CSI-RS / IM and / or participating in data collection (e.g., for one or more active CSI-RS / IMs). Therefore, as illustrated, the UE may send a request to deactivate one or more active CSI-RS / IMs. As noted above, the activation / deactivation decision may be based on various conditions (e.g., regarding processing resources and / or available power).

[0120] In such scenarios, the P / SP CSI-RS / IM resource can be considered active once the UE receives the CSI-RS / IM resource within X ms / slot / subframe / frame before and / or Y ms / slot / subframe / frame after the UE transmits a (active) request to (re- / de-)activate the CSI-RS / IM resource.

[0121] Figure 11Example 1100 depicts an activation request according to certain aspects of this disclosure.

[0122] As illustrated at 1105, the UE may be advised / instructed / configured with one or more (currently) inactive CSI-RS / IMs for UE-side data collection.

[0123] As illustrated at 1110, the UE may decide its preference (e.g., ability or willingness) to receive / process CSI-RS / IM and / or participate in data collection (e.g., for one or more active CSI-RS / IMs among active CSI-RS / IMs). Therefore, as illustrated, the UE may send a request to (re)activate one or more inactive CSI-RS / IMs.

[0124] In such scenarios, if the UE does not expect to receive the CSI-RS / IM resource within X ms / slot / subframe / frame before and / or Y ms / slot / subframe / frame after transmitting a (active) request to (re- / de-)activate the CSI-RS / IM resource, the SP / AP CSI-RS / IM resource can be considered inactive.

[0125] In some aspects, as mentioned above Figures 9 to 11 Such (re)activation requests may be based on indicating one or more CSI-RS / CSI-IM resource IDs, or indicating one or more CSI-RS / CSI-IM resource set IDs.

[0126] In some respects, requests for certain CSI-RS / CSI-IM resources may be permitted only for (re)activation or deactivation. For example, activation and / or deactivation requests may be permitted only for (e.g., associated) CSI-RS / CSI-IM resources within a candidate CSI-RS / IM resource group configured / indicated by the gNB (e.g., candidate groups may be RRC configured per cell / BWP by indicating individual CSI-RS / IM resource IDs or CSI-RS / IM resource set IDs).

[0127] In some respects, activation and / or deactivation requests may only be permitted for CSI-RS / CSI-IM resources that are not associated with any CSI report (e.g., associated resources).

[0128] In some respects, activation and / or deactivation requests may only be permitted for CSI-RS / CSI-IM resources (e.g., their associated resources) that are indicated for use in a specific type or purpose of CSI reporting. reportQuantity (Set to "0" or "None").

[0129] Figure 12Example 1200 depicts a request based on a Media Access Control (MAC) Control Element (CE) according to certain aspects of this disclosure.

[0130] In some aspects, activation and / or deactivation requests may be sent via MAC-CE 1212. As illustrated, a MAC-CE-based request may include (e.g., a separate SCI-RS / IM resource ID selected from NZP-CSI-RS resource set candidate group 1210) or (e.g., a separate CSI-RS / IM resource set ID selected from NZP-CSI-IM resource set candidate group 1230). In some aspects, a MAC-CE-based request may include an indicator specifying whether the request is for activation or deactivation of the indicated resource / resource set. Each CSI-RS / IM resource(set) ID may refer to a reordered candidate group 1220.

[0131] In some respects, each individually indicated CSI-RS resource / resource set may be accompanied by an indicator specifying whether the request is for activation or deactivation of the resource / resource set. In other respects, the request for the indicated resource / resource set may be identified (e.g., implicitly) based on certain rules. For example, in the time slot where a MAC-CE-based request is transmitted, if the corresponding resource / resource set is considered active / inactive (e.g., based on the aforementioned criteria), then the request is considered to be for deactivating / activating the resource / resource set, respectively.

[0132] In some aspects, a MAC-CE-based request may include an indicator specifying whether the indicated resource / resource set ID is associated with a Non-Zero Power (NZP)-CSI-RS or CSI-IM resource / resource set. In other aspects, each individually indicated resource / resource set may be accompanied by an indicator specifying whether the request for the resource is for an NZP-CSI-RS or CSI-IM resource / resource set.

[0133] In some respects, the indicated resource / resource set ID may be based on a resource / resource set ID configured in the associated serving cell. In other respects, such a resource ID may be based on a reordered ID within a candidate group configured / indicated by a separate network.

[0134] Figure 13 An example of a request based on two-part channel state information (CSI) according to certain aspects of this disclosure is described.

[0135] In some cases, activation and / or deactivation requests can be transmitted in multiple parts. For example, such as... Figure 13 As illustrated in Example 1300, such a request can be transmitted as a two-part CSI request (CSI Part 1 and CSI Part 2).

[0136] As illustrated, the first part (request #1 activation or request #2 deactivation) can be transmitted via the CSI report. When the UE is configured with its reportQuantity set based on the two-part CSI payload, various options exist for conveying the deactivation / activation request. According to the first option, the UE can provide an indication of the number of CSI-RS / IM resources associated with the request in CSI part 1 (1310) of the CSI report. The UE can then report the specific CSI-RS / IM resource ID in CSI part 2 (1320) of the CSI report.

[0137] There are various methods to identify whether a request is for activating or deactivating a CSI-RS resource. For example... Figure 13 As illustrated, in some cases, CSI section 1 1310 may include an indicator specifying whether the request is for activating or deactivating the indicated resource. Alternatively, in CSI section 2 1320, each individually indicated resource may be accompanied by an indicator specifying whether the request for the resource is for activating or deactivating the resource. As another alternative, the request for the indicated resource may be implicitly identified as for activation or deactivation based on one or more rules (e.g., based on the time slot in which the MAC-CE-based request is transmitted, if the corresponding resource is considered active / deactivated, then the request is considered for deactivating / activating such a resource).

[0138] Various options exist for how to identify whether a request applies to NZP-CSI-RS or CSI-IM. In some cases, CSI section 1 1310 may include an indicator specifying whether the indicated resource ID is associated with an NZP-CSI-RS resource or a CSI-IM resource. Alternatively, in CSI section 2, each individually indicated resource may be accompanied by an indicator specifying whether the request for the resource is for an NZP-CSI-RS resource (by indicating a candidate group of NZP-CSI-RS resource sets, as shown in 1322) or a CSI-IM resource (by indicating a candidate group of CSI-IM resource sets, as shown in 1324). Various ways exist for interpreting the indicated CSI-RS / IM resource IDs. For example, the interpretation of the indicated resource ID may be based on the resource ID configured in the associated ServCell. Alternatively, such resource IDs may be interpreted based on reordered IDs in a candidate group individually configured / indicated in the gNB.

[0139] There are various options for how to identify the number of bits used to indicate the quantity of CSI-RS resources in CSI Part 1 and the maximum number of CSI-RS resources that can be indicated (e.g., the 3-bit example shown at 1312 allows indicating a maximum value of 7). The maximum number of resources that a UE can request via CSI reporting (and the corresponding number of bits used to report the quantity of resources associated with the request via CSI Part 1) can be configured by RRC in the CSI reporting settings or predefined (e.g., specified in the standard).

[0140] Another option for a single CSI-RS resource set ID is to replace it with a reference to a CSI-RS / CSI-IM resource set. Figure 13 The references to CSI-RS / CSI-IM resources shown are illustrated. The various mechanisms described for indicating multiple specific resources and which specific resources, whether a request is for activation / deactivation, and what type of resource are also applicable to this option.

[0141] like Figure 14 As illustrated in Example 1400, activation (request #1) / deactivation (request #2) requests can also be communicated via a request based on Part 1 CSI. In this way, the request can be transmitted via a CSI report, for example, where the UE is configured with its reportQuantity based on the Part 1 CSI payload 1420 CSI report setting.

[0142] According to one option, the request combination list can be further configured via a separate CSI-RS / IM resource ID, the CSI reporting settings associated with the corresponding ServCell / BWP, or a separate RRC configuration, as indicated at 1410. As indicated at 1420, the CSI payload can indicate one or more request combinations among the configured request combinations. A request combination can refer to one or more NZP-CSI-RS resources (in the ZP-CSI-RS resource set candidate group, as shown at 1414) and / or CSI-IM RS resources (in the ZP-CSI-RS resource set candidate group, as shown at 1416).

[0143] Each request combination in the list may include one or more candidate CSI-RS resources. In some cases, the reportQuantity for CSI report settings may include one or more request combination IDs associated with the request combination list. In some cases, the gNB may use an additional MAC-CE to activate a subset of request combinations, such that the UE can be restricted to selecting from the subset activated by the MAC-CE when transmitting CSI reports.

[0144] As indicated at 1412, there may be at least one (“dummy”) request combination that indicates no resource has been requested. Various methods exist for identifying whether a request is for activating or deactivating a CSI-RS / IM resource. In some cases, each request combination may include an information element (IE) specifying whether the request is for activating or deactivating the associated resource.

[0145] Alternatively, in each request combination, each individually indicated resource may be accompanied by an indicator specifying whether the request for the resource is for activation or deactivation. Alternatively, the request for the indicated resource may be implicitly identified as for activation or deactivation based on rules specified in the master proposal (i.e., in the time slot where a MAC-CE-based request is transmitted, if the corresponding resource is considered active / deactivated, then the request is considered for deactivating / activating such a resource).

[0146] In some cases, each request combination may include an IE specifying whether the indicated resource ID is associated with an NZP-CSI-RS resource or a CSI-IM resource. Alternatively, in each request combination, each individually indicated resource may be accompanied by an indicator specifying whether the request for the resource is for an NZP-CSI-RS resource or a CSI-IM resource.

[0147] There are various options for how to interpret the indicated CSI-RS / IM resource ID. In some cases, the resource ID configured in the request combination can be interpreted based on the resource ID configured in the associated ServCell. As an alternative, such resource IDs can be interpreted based on the reordered IDs in the candidate group configured / indicated separately by the gNB (as referenced above). Figure 12 (As described).

[0148] Another option for using a separate CSI-RS / IM resource set ID is to replace it with a reference to the CSI-RS / CSI-IM resource set. Figure 14 The references to CSI-RS / CSI-IM resources shown are illustrated. The various mechanisms described for indicating multiple specific resources and which specific resources, whether a request is for activation / deactivation, and what type of resource are also applicable to this option.

[0149] In some cases, the UE may transmit a scheduling request (SR) to request resources for transmitting an activation / deactivation request. For example, in such cases, the UE may transmit an SR with a dedicated SR configuration associated with the activation / deactivation request, which instructs the UE to request scheduling using an appropriate PUSCH or activation using an appropriate CSI report for transmitting the activation / deactivation request.

[0150] In some cases, the reporting volume (indicating the type of parameter communicated in a CSI report) can be compared with other types of CSI reporting volume parameters. reportQuantity This value can be used in conjunction with other values. For request messages based on CSI reports, this type of reportQuantity (for requests based on PUSCH / CSI reports) can be used with other types of... reportQuantity Configure coexistence. In some cases, the number of CSI processing units (CPUs) occupied may not change. This may be related to the fact that reportQuantity only contains this coexistence type other than the requested resource or resource set. reportQuantity The situation is the opposite.
