[0003] All aspects of this disclosure relate to wireless communication in general, and to reference signal resources for identifying channel state information for spatial or power domain adaptation.

[0004] Related technical descriptions

[0005] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a collection of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0006] A wireless network may include one or more network nodes that support communication for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with network nodes via downlink and uplink communication. A "downlink" (or "DL") refers to the communication link from the network node to the UE, and an "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via local links (e.g., sidelinks (SL), wireless local area network (WLAN) links, and / or wireless personal area network (WPAN) links, etc.).

[0007] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different UEs to communicate at the city, country, region, or global level. New Radio (NR) (also known as 5G) is a collection of enhancements to the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband internet access by: improving spectrum efficiency; reducing costs; improving service; utilizing new spectrum; and better integrating with other open standards by using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (CP-OFDM) and CP-OFDM or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink; and supporting beamforming, Multiple-Input Multiple-Output (MIMO) antenna technologies and carrier aggregation.

[0032] User equipment (UE) can measure Channel State Information (CSI) Reference Signals (CSI-RS) and provide CSI feedback to network entities for beam management and communication scheduling. CSI-RS can be part of a CSI-RS resource associated with a two-dimensional antenna array. Network entities (e.g., gNB) can transmit CSI-RS signals associated with the entire antenna array, and the UE can generate multiple CSIs for different antenna subarrays using the same received CSI-RS signal; this is called spatial domain adaptation. Each subarray is associated with a subset of CSI-RS ports and a corresponding subset of the time / frequency / code resources of the CSI-RS signal. The UE uses different subarrays for CSI calculation. The UE can also generate CSIs based on power offset values; this is called power domain adaptation.

[0033] The UE can process CSI based on CSI processing metrics (e.g., using CSI-RS measurements to generate CSI). For the purposes of this discussion, two CSI processing metrics are related: Central Processing Unit (CPU) occupancy, which provides a measure of the processing load at the UE; and the number of concurrently active CSI-RS resources and ports, which provides a measure of memory usage. As part of its capability information, the UE reports the number of CPUs it can process simultaneously (via parameters in the component carriers). simultaneousCSI-ReportsPerCC and parameters across all component carriers simultaneousCSI- ReportsAllCC ), which is represented as There is a CPU usage count. This indicates the processing unit currently being used for the ongoing CSI report. At any given time, One unused CPU slot can be used to prepare additional CSI reports. Once no more unused CPU slots are available, the UE will not process any more CSIs. Even when no unused CPU slots are available, the UE can still transmit CSI reports, but for CSI reports exceeding the limit, the UE is allowed to transmit outdated reports. A count is set whenever CSI calculation begins. Increase ,in This is the load specification for the new CSI process. The count is recorded each time a CSI calculation ends. reduce ,in This specifies the load for the completed CSI procedure.

[0034] For non-periodic CSI reports, the CPU is occupied at the end of the last symbol of the Physical Downlink Control Channel (PDCCH) carrying the CSI trigger, and released at the end of the last symbol of the Physical Uplink Shared Channel (PUSCH) or Physical Uplink Control Channel (PUCCH) carrying the report. For the first report in a semi-persistent CSI report sequence on the PUSCH, the CPU is occupied at the end of the last symbol of the PDCCH that enables the CSI process, and released at the end of the last symbol of the PUSCH carrying the first report. For periodic and semi-persistent CSI reports, except for the first report in a semi-persistent CSI report sequence on the PUSCH, the CPU is occupied at the latest CSI measurement resource (CSI-RS, CSI for IM (CSI-IM), or Synchronization Signal Block (SSB)) available for the report, and released at the end of the last symbol of the PUCCH or PUSCH carrying the report. The latest such CSI-RS resource is formally defined as no later than the latest resource of the so-called CSI reference resource. The timing of the CSI reference resource is defined separately. If multiple CSI-RS resources are used for a given report and they do not occur at the same time, the earliest of the multiple CSI-RS resources is counted.

[0035] The UE can also report the maximum number of simultaneously active CSI-RS resources and ports, such as the maximum number of simultaneously active non-zero power (NZP) CSI-RS resources per component carrier (via parameters). maxNumberSimultaneousNZP- CSI-RS-PerCC The maximum total number of ports in all simultaneously active NZP CSI-RS resources for each component carrier (via parameter) NumberPortsSimultaneousNZP-CSI-RS-PerCC The maximum number of NZPCSI-RS resources that are simultaneously active across all component carriers (via parameter) maxNumberSimultaneousNZP-CSI-RS-ActBWP-AllCC ), and the maximum total number of ports in all simultaneously active NZP CSI-RS resources across all component carriers (via parameters totalNumberPortsSimultaneousNZP-CSI-RS-ActBWP-AllCC ).

[0036] For the purpose of determining the number of concurrently active CSI-RS resources, a CSI-RS resource can be considered active according to the following rules: For non-periodic CSI-RS resources, the CSI-RS resource and its ports become active at the end of the last symbol of the PDCCH carrying the CSI trigger, and become inactive at the end of the last symbol of the PUSCH carrying the report. For semi-persistent CSI-RS resources, the CSI-RS resource and its ports become active when the CSI-RS resource is enabled, and become inactive when the CSI-RS resource is disabled. For periodic CSI-RS resources, the CSI-RS resource and its ports become active when the CSI-RS resource is configured, and become inactive when the CSI-RS resource configuration is released.

[0037] In some deployments, if a CSI-RS resource is referenced by one or more CSI report settings... X Then, the CSI-RS resource and the CSI-RS ports within that CSI-RS resource are identified (e.g., counted). X This can be based on the assumption that for each CSI reporting setting that references CSI-RS resources, the CSI-RS resources must be stored in the UE's memory. However, in spatial and power domain adaptations, multiple sub-configurations can be applied to a given CSI-RS resource, and different combinations of these sub-configurations can be active for CSI reporting at a given time. These different sub-configurations can also indicate different numbers of CSI-RS ports, leading to ambiguity regarding how CSI-RS resources and CSI-RS ports should be counted. This ambiguity can result in suboptimal utilization of UE resources, such as memory and processor resources.

[0038] Various aspects of this disclosure generally relate to CSI reporting for spatial domain and / or power domain adaptation. Some aspects more specifically relate to identifying (e.g., counting) CSI-RS resources and / or ports in conjunction with spatial domain and / or power domain adaptation. In some aspects, the UE may receive a CSI report configuration indicating CSI-RS resources and a configuration set for channel measurements. Each configuration in the configuration set may indicate a transmission setting for the CSI-RS, and this transmission setting may relate to at least one of a CSI-RS port configuration or a power offset for the CSI-RS. The UE may identify the number of active CSI-RS resources associated with the CSI-RS report and the number of active CSI-RS ports for those CSI-RS resources. The number of active CSI-RS resources and the number of active CSI-RS ports may correspond to a configuration subset of the configuration set and may be at least partially based on the CSI-RS resource type. For example, the subset may reference CSI-RS resources and may be active for the CSI report.

[0039] Specific aspects of this disclosure can be used to achieve one or more of the following potential advantages. In some aspects, by identifying the number of CSI-RS resources and CSI-RS ports corresponding to a configuration subset of the configuration set, ambiguity regarding how CSI-RS resources and ports should be counted is reduced. Furthermore, the UE can utilize processor and memory resources more efficiently, and CSI reporting can be tailored to the complexity of the UE's processor and memory resources.

[0040] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Those skilled in the art will appreciate that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or method of practice. Furthermore, the scope of this disclosure is intended to cover such apparatus or methods practiced using structures, functions, or structures and functions other than or different from the various aspects of the disclosure set forth herein.

[0041] Various devices and techniques will now be used to illustrate several aspects of a telecommunications system. These devices and techniques will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements may be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0042] Although terms generally associated with 5G or New Radio (NR) Radio Access Technology (RAT) may be used herein to describe aspects, aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or 5G and later (e.g., 6G) RATs.

[0043] Figure 1 This is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network or elements of a 4G (e.g., LTE) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), or other entities. Network node 110 is an example of a network node communicating with UE 120. As shown, network node 110 may include one or more network nodes. For example, network node 110 can be an aggregated network node, meaning that the aggregated network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). As another example, network node 110 can be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 is configured to utilize a protocol stack that is physically or logically distributed among two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0044] In some examples, network node 110 is or includes network nodes (such as RUs) that communicate with UE 120 via a radio access link. In some examples, network node 110 is or includes network nodes (such as DUs) that communicate with other network nodes 110 via a fronthaul or midhaul link. In some examples, network node 110 is or includes network nodes (such as CUs) that communicate with other network nodes 110 via a midhaul link or with the core network via a backhaul link. In some examples, network node 110 (such as aggregated network node 110 or decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. For example, network node 110 may include NR base stations, LTE base stations, Node Bs, eNBs (e.g., in 4G), gNBs (e.g., in 5G), access points, Transmit / Receive Points (TRPs), DUs, RUs, CUs, network mobility elements, core network nodes, network elements, network equipment, RAN nodes, or combinations thereof. In some examples, network nodes 110 can interconnect with each other or with one or more other network nodes 110 in the wireless network 100 using any suitable transport network through various types of fronthaul interfaces, midhaul interfaces, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks).

[0045] In some examples, network node 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), depending on the context in which the term is used, the term "cell" may refer to the coverage area of ​​network node 110 or a network node subsystem serving that coverage area. Network node 110 may provide communication coverage for macrocells, picocells, femtocells, or another type of cell. A macrocell may cover a relatively large geographic area (e.g., with a radius of several kilometers) and may allow unrestricted access by UE 120 with a service subscription. A picocell may cover a relatively small geographic area and may allow unrestricted access by UE 120 with a service subscription. A femtocell may cover a relatively small geographic area (e.g., a residential area) and may allow restricted access by UE 120 associated with that femtocell (e.g., UE 120 in a Closed Subscriber Group (CSG)). Network node 110 used for macrocells may be referred to as a macro network node. Network node 110 used for picocells may be referred to as a pico network node. The network node 110 used for femtocells can be referred to as a femtocell network node or a home network node. Figure 1In the example shown, network node 110a can be a macro network node for macro cell 102a, network node 110b can be a pico network node for pico cell 102b, and network node 110c can be a femto network node for femto cell 102c. Network nodes can support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographical area of ​​the cells may move depending on the location of the mobile network node 110 (e.g., a mobile network node).

[0046] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, "base station" or "network node" may refer to a CU, DU, RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with network node 110). In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which may be located in the same geographical location or different geographical locations) may be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of that function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions can be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one base station function rather than another. In this way, a single device may include more than one base station.

[0047] Wireless network 100 may include one or more relay stations. A relay station is a network node that receives data transmissions from an upstream node (e.g., network node 110 or UE 120) and transmits the data to a downstream node (e.g., UE 120 or network node 110). A relay station may be a UE 120 that can relay transmissions to other UE 120s. Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. The network node 110 for relay communication may be referred to as a relay station, relay base station, relay network node, relay node, or relay, etc.

[0048] The wireless network 100 can be a heterogeneous network, comprising different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, or relay network nodes. These different types of network nodes 110 may have different transmit power levels, different coverage areas, or different effects on interference in the wireless network 100. For example, macro network nodes may have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0049] Network controller 130 may be coupled to or communicate with network node set 110, and may provide coordination and control for these network nodes 110. Network controller 130 may communicate with network nodes 110 via a backhaul or midhaul link. Network nodes 110 may also communicate directly with each other, or indirectly via a wireless or wired backhaul link. In some aspects, network controller 130 may be a CU or core network device, or may include a CU or core network device.

[0050] UE 120 may be distributed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a terminal, a mobile station, or a subscriber unit. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, a UE function of a network node, or any other suitable device configured to communicate via wireless or wired media.

[0051] Generally, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology or air interface. A frequency can also be referred to as a carrier or frequency channel. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0052] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, or channels by frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating bands. In 5G NR, two initial operating bands have been designated as frequency ranges FR1 (410MHz to 7.125GHz) and FR2 (24.25GHz to 52.6GHz). Although a portion of FR1 is greater than 6GHz, in various documents and articles, FR1 is often (interchangeably) referred to as the “sub-6GHz” band. Similar naming issues sometimes occur with FR2, which is often (interchangeably) referred to in documents and articles as the “millimeter wave” band, although this is different from the Extremely High Frequency (EHF) band (30GHz to 300GHz) designated as a “millimeter wave” band by the International Telecommunication Union (ITU).

[0053] The frequencies between FR1 and FR2 are generally referred to as intermediate frequency (IF) bands. Recent 5G NR studies have designated the operating bands for these IF bands as the frequency range designation FR3 (7.125 GHz to 24.25 GHz). Bands falling within FR3 can inherit FR1 or FR2 characteristics, thus effectively extending the features of FR1 or FR2 into the IF band. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been designated as the frequency range designations FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0054] In light of these examples, unless otherwise specifically stated, the term "below 6 GHz" as used herein can broadly refer to frequencies less than 6 GHz, frequencies within FR1, or frequencies that may include intermediate frequency bands. Furthermore, unless otherwise specifically stated, the term "millimeter wave" as used herein can broadly refer to frequencies that may include intermediate frequency bands, frequencies within FR2, FR4, FR4-a, FR4-1, or FR5, or frequencies within the EHF band. It is conceivable that the frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0055] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive a CSI report configuration indicating CSI-RS resources and a sub-configuration set for channel measurements, wherein each sub-configuration in the sub-configuration set corresponds to a CSI-RS transmission setting; identify the number of CSI-RS resources and the number of CSI-RS ports for the CSI-RS resources, wherein the number of CSI-RS resources and the number of CSI-RS ports correspond to a sub-configuration subset of the sub-configuration set; and transmit one or more CSI reports based on the subset of the sub-configuration set. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0057] Figure 2 This is a diagram illustrating example 200 of communication between network node 110 and UE 120 in a wireless network 100 according to this disclosure. Network node 110 may be equipped with antenna sets 234a to 234t, such as... T One antenna ( T ≥1). UE 120 may be equipped with antenna sets 252a to 252r, such as R One antenna ( R ≥1). Network node 110 of Example 200 includes one or more radio frequency components, such as antenna 234 and modem 232. In some examples, network node 110 may include an interface, communication components, or another component that facilitates communication with UE 120 or another network node. Some network node 110 may not include radio frequency components that facilitate direct communication with UE 120, such as one or more CUs or one or more DUs.

[0058] At network node 110, transmitting processor 220 can receive data from data source 212 intended for use by UE 120 (or UE set 120). Transmitting processor 220 can use one or more Channel Quality Indicators (CQIs) received from UE 120 to select one or more modulation and decoding schemes (MCSs) for that UE 120. Network node 110 can use the MCS selected for UE 120 to process (e.g., encode and modulate) the data for UE 120 and can provide data symbols to UE 120. Transmitting processor 220 can process system information (e.g., semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, or upper-layer signaling) and provide overhead symbols and control symbols. Transmitting processor 220 can generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, or reference symbols (if applicable), and can direct to a corresponding set of modems 232 shown as modems 232a to 232t (e.g., T A set of output symbol streams (e.g., modems) is provided by a modem. T Each output symbol stream can be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 can use a corresponding modulator component to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 can also use a corresponding modulator component to process (e.g., convert to analog, amplify, filter, or upconvert) the output sample stream to obtain a downlink signal. Modems 232a to 232t can be connected via a corresponding set of antennas 234 (e.g., T Each antenna (shown as antennas 234a to 234t) is used to transmit a set of downlink signals (e.g., T (One downlink signal).

[0059] At UE 120, the set of antennas 252 (shown as antennas 252a to 252r) can receive downlink signals from network node 110 or other network nodes 110, and can transmit signals to the set of modems 254 (e.g., R Each modem (shown as modems 254a to 254r) provides a set of received signals (e.g., REach received signal may be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, down-convert, or digitize) the received signal to obtain an input sample. Each modem 254 may use a demodulator component to further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 may obtain the received symbols from modem 254, perform MIMO detection on the received symbols where applicable, and provide the detected symbols. Receiver processor 258 may process (e.g., demodulate and decode) the detected symbols, provide the decoded data for UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. Channel processor may determine Reference Signal Received Power (RSRP) parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Received Quality (RSRQ) parameters, or CQI parameters, etc. In some examples, one or more components of UE 120 may be included in housing 284.

[0060] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, for example, in a core network. Network controller 130 may communicate with network node 110 via communication unit 294.

[0061] One or more antennas (e.g., antennas 234a to 234t or antennas 252a to 252r) may include or be included in the following: one or more antenna panels, one or more antenna groups, one or more collections of antenna elements, or one or more antenna arrays, etc. Antenna panels, antenna groups, collections of antenna elements, or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), coplanar antenna element collections, non-coplanar antenna element collections, or coupled to one or more transmitting or receiving components (such as...). Figure 2 One or more antenna elements (one or more components).

[0062] On the uplink, at UE 120, transmit processor 264 can receive and process data from data source 262 and control information (e.g., reports including RSRP, RSSI, RSRQ, or CQI) from controller / processor 280. Transmit processor 264 can generate reference symbols for one or more reference signals. Symbols from transmit processor 264 may be pre-decoded by TX MIMO processor 266 where applicable, further processed by modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to network node 110. In some examples, modem 254 of UE 120 may include a modulator and demodulator. In some examples, UE 120 includes a transceiver. The transceiver may include antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, or any combination of TX MIMO processor 266. The transceiver may be used by processor (e.g., controller / processor 280) and memory 282 to perform textual (e.g., reference) functions. Figures 4 to 11 ( ) any aspect of the process described in the process.

[0063] At network node 110, uplink signals from UE 120 or other UEs may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232, shown as DEMOD), detected by MIMO detector 236 where applicable, and further processed by receiver processor 238 to obtain decoded data and control information transmitted via UE 120. Receiver processor 238 may provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Network node 110 may include communication unit 244 and may communicate with network controller 130 via communication unit 244. Network node 110 may include scheduler 246 to schedule one or more UEs 120 for downlink or uplink communication. In some examples, modem 232 of network node 110 may include modulator and demodulator. In some examples, network node 110 includes transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to execute this document (e.g., reference). Figures 4 to 11 ( ) any aspect of the process described in the process.

[0064] In some respects, the controller / processor 280 may be a component of a processing system. A processing system can typically be a system or a series of machines or components that receive input and process it to produce output (which may be passed to other systems or components, such as UE 120). For example, the processing system of UE 120 may be a system that includes various other components or sub-components of UE 120.

[0065] The processing system of UE 120 can interface with one or more other components of UE 120, and can process information (such as input or signals) received from one or more other components, or can output information to one or more other components. For example, the chip or modem of UE 120 may include: a processing system, a first interface for receiving or acquiring information, and a second interface for outputting, transmitting, or providing information. In some examples, the first interface may be an interface between the processing system of the chip or modem and a receiver, allowing UE 120 to receive information or signal input and to pass information to the processing system. In some examples, the second interface may be an interface between the processing system of the chip or modem and a transmitter, allowing UE 120 to transmit information output from the chip or modem. Those skilled in the art will readily recognize that the second interface may also acquire or receive information or signal input, and the first interface may also output, transmit, or provide information.

[0066] In some respects, the controller / processor 240 may be a component of a processing system. A processing system can typically be a system or a series of machines or components that receive input and process it to produce output (which may be passed to other systems or components, such as network node 110). For example, the processing system of network node 110 may be a system that includes various other components or sub-components of network node 110.

Those skilled in the art will readily recognize that the second interface may also acquire or receive information or signal input, and the first interface may also output, transmit, or provide information.

[0068] The controller / processor 240 of network node 110, the controller / processor 280 of UE 120, or Figure 2 Any other component may perform one or more techniques associated with CQI operations, as described in more detail elsewhere herein. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, or... Figure 2 Any other component (or combination of components) can perform or instruct, for example Figure 12 The operation of process 1200 and / or other processes as described herein. Memory 242 and memory 282 may store data and program code for network node 110 and UE 120, respectively. In some examples, memory 242 and memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code or program code) for wireless communication. For example, one or more instructions may cause one or more processors, UE 120, or network node 110 to perform or direct, for example, when executed by one or more processors of network node 110 or UE 120 (e.g., directly executed, or executed after compilation, transformation, or interpretation). Figure 12 The operation of process 1200 and / or other processes as described herein. In some examples, the execution instructions may include run instructions, transform instructions, compile instructions and / or interpret instructions, etc.

[0069] In some aspects, UE 120 includes components for receiving CSI report configurations indicating CSI-RS resources and sub-configuration sets for channel measurements, wherein each sub-configuration in the sub-configuration set corresponds to a CSI-RS transmission setting; components for identifying the number of CSI-RS resources and the number of CSI-RS ports for the CSI-RS resources, wherein the number of CSI-RS resources and the number of CSI-RS ports correspond to a sub-configuration subset of the sub-configuration set; and / or components for transmitting one or more CSI reports based on the subset of the sub-configuration set. Components enabling UE 120 to perform the operations described herein may include, for example, one or more of the following: communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0070] In some aspects, UE 120 includes components for receiving channel state information (CSI) report configurations indicating channel state information reference signal (CSI-RS) resources and configuration sets for channel measurement, wherein each configuration in the configuration set indicates a transmission setting for the CSI-RS, wherein the transmission setting relates to at least one of a CSI-RS port configuration or a CSI-RS power offset; components for identifying the number of active CSI-RS resources and the number of active CSI-RS ports for the CSI-RS resources, wherein the number of active CSI-RS resources and the number of active CSI-RS ports correspond to a configuration subset of the configuration set and are at least partially based on the CSI-RS resource type; and components for transmitting one or more CSI reports based on the configuration subset of the configuration set.

[0071] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0072] In some respects, individual processors can be described as performing all functions executed by the one or more processors. In other respects, the one or more processors can jointly perform a set of functions. For example, the processors of a first set (one or more) of the one or more processors can be described as performing a first function executed by the one or more processors, and the processors of a second set (one or more) of the one or more processors can be described as performing a second function executed by the one or more processors. The first set of processors and the second set of processors can be the same set of processors or can be different sets of processors. The reference to "one or more processors" should be understood as referring to a combination of functions. Figure 2 Any one or more processors described. The reference to "one or more memories" should be understood to refer to any one or more memories of the corresponding device, such as those in conjunction with... Figure 2 The memory described. For example, a function described as being performed by one or more memories can be performed by the same subset of the one or more memories or by different subsets of the one or more memories.

[0073] As indicated above, Figure 2 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 2 The examples described are different.

[0074] Figure 3 This is an illustration of an example disaggregated base station architecture 300 according to this disclosure. The disaggregated base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 via one or more disaggregated control units (such as near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a Service Management and Orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via a corresponding midhaul link (such as via an F1 interface). Each DU 330 may communicate with one or more RUs 340 via a corresponding fronthaul link. Each RU 340 may communicate with one or more UEs 120 via a corresponding radio frequency (RF) access link. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0075] Each of these units (including CU 310, DU 330, RU 340) and the near-RT RIC 325, non-RT RIC 315, and SMO frame 305 may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each of these units, or an associated processor or controller providing instructions to one or more communication interfaces of the respective unit, may be configured to communicate with one or more other units via transmission media. In some examples, each unit may include a wired interface and a wireless interface configured to receive signals or transmit signals to one or more other units via a wired transmission media, and the wireless interface may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals or transmit signals to one or more other units via a wireless transmission media, or both.

[0076] In some aspects, the CU 310 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC) functions, Packet Data Convergence Protocol (PDCP) functions, or Service Data Adaptation Protocol (SDAP) functions, etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by the CU 310. The CU 310 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP) functions), control plane functions (e.g., Central Unit-Control Plane (CU-CP) functions), or combinations thereof. In some implementations, the CU 310 can be logically divided into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 310 can be implemented to communicate with the DU 330 for network control and signaling purposes, as needed.

[0077] Each DU 330 may correspond to a logical unit comprising one or more base station functions for controlling the operation of one or more RU 340s. In some aspects, the DU 330 may host one or more of the Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, and one or more high physical (PHY) layers, at least in part, according to functional splits (such as those defined by 3GPP). In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as those implemented by one or more modules for Fast Fourier Transform (FFT), Inverse FFT (iFFT), Digital Beamforming, or Physical Random Access Channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0078] Each RU 340 can implement lower-layer functionality. In some deployments, the RU 340 controlled by the DU 330 can correspond to a logical node that hosts RF processing functions or low-PHY layer functions, such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, based on function splitting (e.g., function splitting defined by 3GPP) (such as lower-layer function splitting). In this architecture, each RU 340 can be operated to handle over-the-air (OTA) communications with one or more UE 120s. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration allows each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0079] The SMO framework 305 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 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, the SMO framework 305 can be configured to interact with cloud computing platforms such as the Open Cloud (O-Cloud) platform 390 to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RTTRIC 325. In some specific implementations, the SMO framework 305 may communicate with the hardware aspects of the 4G RAN, such as the Open eNB (O-eNB) 311, via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0080] The non-RT RIC 315 can be configured to include logical functions that enable 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 325. The non-RT RIC 315 can be coupled to or communicate with the near-RT RIC 325, such as via an A1 interface. The near-RT RIC 325 can be configured to include logical functions that enable near real-time control and optimization of RAN elements and resources through data collection and actions via an interface such as an E2 interface, connecting one or more CU 310s, one or more DU 330s, or both, and O-eNBs to the near-RT RIC 325.

[0081] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions via the SMO framework 305 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0082] As indicated above, Figure 3 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 3 The examples described are different.

[0083] Figure 4 This is a diagram illustrating example 400 of spatial adaptation according to this disclosure.

[0084] Massive MIMO provides high spectral efficiency and extended coverage by using a large number of antennas for communication. For downlink transmission, network nodes supporting massive MIMO can be equipped with a large number of transceiver chains (e.g., the 64 transceiver chains in FR1 are typically deployed in commercial 5G networks, especially at 3.5 GHz and / or higher carrier frequencies). Each transceiver chain can be connected to one or more power amplifiers. Power amplifiers can consume a significant portion of the network node's energy (e.g., 70% to 80% of base station power). To control or reduce network power consumption, a cell can turn one or more power amplifiers on or off (depending on time and frequency resource utilization within the cell). Equivalently, a cell can turn one or more transceiver chains on or off.

[0085] Spatial adaptation at a network node can include deactivating one or more antenna panels (spatial elements, ports) to reduce the number of active antenna panels. Example 400 shows four antenna panels for a network node (e.g., a gNB). The network node can deactivate three of these four antenna panels. These three deactivated panels are shown as off. Indications related to spatial adaptation can help the UE adapt its CSI-RS configuration to dynamic or semi-persistent CSI-RS enable or disable, or reconfigure the CSI-RS configuration for the number of adapted spatial elements or ports. Network entities can do this via a selected trigger state (e.g., CSI-AperiodicTriggerStateList , CSI-SemiPersistentOnPUSCH- TriggerStateListThis allows for dynamic selection of CSI reporting configurations, such as via Media Access Control Control Element (MAC CE) or Downlink Control Information (DCI).

[0086] Power control offsets can be used to adapt the transmit power of CSI-RS. In the first step, CSI feedback can be provided for the adaptation of the power offset value. In the second step, the appropriate power offset configuration can be used to transmit the Physical Downlink Shared Channel (PDSCH).

[0087] As indicated above, Figure 4 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 4 The examples described are different.

[0088] Figures 5A to 5B This is a diagram illustrating an example of a CSI-RS beam management process according to this disclosure. For example... Figure 5A As shown, UE 120 communicates with network node 110 in a wireless network (e.g., wireless network 100). However, Figure 5A The device shown is provided as an example, and the wireless network can support communication and beam management between other devices (e.g., between UE 120 and network node 110 or TRP, between mobile terminal node and control node, between IAB child node and IAB parent node, and / or between scheduled node and scheduling node). In some aspects, UE 120 and network node 110 may be in a connected state (e.g., RRC connected state).

[0089] like Figure 5A As shown, Example 500 may include a network node 110 (e.g., one or more network node devices such as RU, DU, and / or CU, etc.) communicating with UE 120 to perform beam management using CSI-RS. Example 500 depicts a first beam management procedure (e.g., P1 CSI-RS beam management). The first beam management procedure may be referred to as a beam selection procedure, an initial beam acquisition procedure, a beam scanning procedure, a cell search procedure, and / or a beam search procedure. Figure 5A As shown in Example 500, CSI-RS can be configured to be transmitted from network node 110 to UE 120. CSI-RS can be configured to be periodic (e.g., using RRC signaling), semi-persistent (e.g., using Media Access Control Control Element (MAC-CE) signaling), and / or non-periodic (e.g., using DCI).

[0090] The first beam management process may include network node 110 performing beam scanning on multiple transmit (Tx) beams. Network node 110 may use each transmit beam for beam management to transmit CSI-RS. To enable UE 120 to perform receive (Rx) beam scanning, the network node may use the transmit beams to transmit (e.g., retransmit) each CSI-RS multiple times within the same reference signal (RS) resource set, allowing UE 120 to traverse receive beam scans across multiple transmit instances. For example, if network node 110 has a set of N transmit beams and UE 120 has a set of M receive beams, CSI-RS may be transmitted M times on each of the N transmit beams, allowing UE 120 to receive M instances of CSI-RS per transmit beam. In other words, for each transmit beam of network node 110, UE 120 may perform beam scanning of UE 120's receive beams. Therefore, the first beam management procedure enables UE 120 to measure CSI-RS on different transmit beams using different receive beams to support the selection of beam pairs for the transmit beam of network node 110 / receive beam of UE 120. UE 120 can report the measurements to network node 110 so that network node 110 can select one or more beam pairs for communication between network node 110 and UE 120. Although Example 500 has been described in conjunction with CSI-RS, the first beam management procedure can also use synchronization signal blocks (SSBs) to perform beam management in a similar manner as described above.

[0091] like Figure 5A As shown, Example 510 may include network node 110 communicating with UE 120 to perform beam management using CSI-RS. Example 510 depicts a second beam management procedure (e.g., P2 CSI-RS beam management). This second beam management procedure may be referred to as a beam refinement procedure, a network node beam refinement procedure, a TRP beam refinement procedure, and / or a transmit beam refinement procedure. Figure 5AAs shown in Example 510, CSI-RS can be configured to be transmitted from network node 110 to UE 120. The CSI-RS can be configured to be aperiodic (e.g., using DCI). A second beam management procedure may include network node 110 performing beam scanning on one or more transmit beams. These one or more transmit beams may be a subset of all transmit beams associated with network node 110 (e.g., determined at least in part based on measurements reported by UE 120 in conjunction with the first beam management procedure). Network node 110 may transmit CSI-RS using each of the one or more transmit beams used for beam management. UE 120 may measure each CSI-RS using a single (e.g., the same) receive beam (e.g., determined at least in part based on measurements performed in conjunction with the first beam management procedure). This second beam management procedure enables network node 110 to select the optimal transmit beam at least in part based on (e.g., measurements taken by UE 120 using a single receive beam) the measurements of CSI-RS reported by UE 120.

[0092] like Figure 5A As shown, Example 520 depicts a third beam management procedure (e.g., P3 CSI-RS beam management). This third beam management procedure may be referred to as a beam refinement procedure, a UE beam refinement procedure, and / or a receive beam refinement procedure. As shown in Figure 5 and Example 520, one or more CSI-RSs may be configured to be transmitted from network node 110 to UE 120. The CSI-RS may be configured to be non-periodic (e.g., using DCI). The third beam management procedure may include network node 110 transmitting one or more CSI-RSs using a single transmit beam (e.g., determined at least in part based on measurements reported by UE 120 in conjunction with the first beam management procedure and / or the second beam management procedure). To enable UE 120 to perform receive beam scanning, the network node may transmit (e.g., retransmit) CSI-RS multiple times within the same RS resource set using the transmit beam, allowing UE 120 to perform one or more receive beam scan traversals in multiple transmission instances. The one or more receive beams may be a subset of all receive beams associated with UE 120 (e.g., determined at least in part based on measurements performed in conjunction with the first beam management procedure and / or the second beam management procedure). The third beam management procedure enables network node 110 and / or UE 120 to select the optimal receive beam at least in part based on reported measurements received from UE 120 (e.g., reported measurements of the CSI-RS of the transmit beam using the one or more receive beams).

[0093] In some cases, such as Figure 5BAs shown by reference numeral 530, the enable / disable capability can be associated with logical antenna ports associated with multiple transmit / receive units (TxRUs) (such as TxRU1, TxRU2, and TxRU3), and these logical antenna ports can be enabled or disabled. This is referred to as Type 1 spatial domain (SD) adaptation. In Type 1 SD adaptation, TxRUs can be enabled or disabled. In some other cases, referred to as Type 2 SD adaptation and shown by reference numeral 540, the configuration of the physical antenna elements of the CSI-RS or PDSCH is adapted. This type of adaptation may be useful for FR2, where the number of TxRUs at the network node is limited (such as 1 or 2 TxRUs). In Type 2 SD adaptation, the number of logical antenna ports can remain constant, while the number of physical antenna elements can be adapted, thus affecting the beamforming gain.

[0094] In some cases, such as from a CSI perspective, a Type 1 SD adapter can be an adaptation of the antenna port or transceiver chain at a network node. Conversely, a Type 2 SD adapter can be an adaptation of the transmit power offset value between the CSI-RS and the SSB.

[0095] In some cases, a non-zero power (NZP) CSI-RS resource configuration for channel measurements can be supported within a single resource setting, corresponding to more than one spatial adaptation mode. A spatial adaptation mode can indicate a set of antenna elements or logical antenna ports to be enabled or disabled. In some cases, a resource set with multiple resources can be configured within a resource setting, where each resource is associated with only one spatial adaptation mode. In other cases, for a resource configured within a resource set within a resource setting, that resource can be associated with more than one spatial adaptation mode. One or more resources can be configured within a resource set for channel measurements. In some cases, a CSI reporting configuration can include multiple CSI reporting sub-configurations, where each sub-configuration corresponds to a single spatial adaptation mode. For sub-configurations of the CSI reporting configuration, the UE 120 can be configured with a port subset indication (e.g., a bitmap). The UE 120 can derive reduced NZP CSI-RS resources from the corresponding NZPCSI-RS resources configured within the CSI-RS resource set for channel management. Elsewhere in this document, the configuration of CSI-RS resources and CSI-RS ports is described, including reduced configurations corresponding to the spatial adaptation mode.

[0096] In some cases, the CSI Feedback (CSF) framework may include multiple steps. The first step (e.g., step 1) may be associated with a CSF adapted for spatial elements. The second step (e.g., step 2) may be associated with identifying or transmitting a Physical Downlink Shared Channel (PDSCH) with appropriate spatial element configuration. In some cases, for those with… LIndividual CSI reporting configurations can enable the UE to report within a single reporting instance. N A CSI framework, in which N CSI and from L Individual configuration N Each sub-configuration is associated (where 1≤ N ≤ L ), and each CSI corresponds to a sub-configuration. N =1 can refer to a single CSI signaling, while N >1 can refer to multiple CSI signaling.

[0097] In some cases, for CSI reporting configurations, each sub-configuration for Type 1 SD adaptation may include at least the following: codebook configuration ( CodebookConfig One or more parameters in the codebook configuration, and a port subset indication or resource grouping. One or more parameters in the codebook configuration may include, for example, for multi-pane configuration. n1 - n2 and ng In some cases, this parameter may also include rank restrictions, codebook subset restrictions, and / or the codebook type supported by the PMI (e.g., Type I or Type II). Port subset indications or CSI-RS packets may indicate, for example, the number of reports, reporting frequency configuration, etc. reportFreqConfiguration This includes whether it is explicitly provided or can also be exported (e.g., from CodebookConfig and / or from CSI-RS resource configuration). For CSI reporting configurations, each sub-configuration for Type 2 SD adaptation may include at least the following: an NZP CSI-RS resource set for channel measurements, where different resources may have different power offsets between CSI-RS and SSB. In some cases, the number of reports may also be included.

[0098] In one example, the CSI reporting configuration for Type 1 SD adaptation, indicated by a port subset, may have three sub-configurations. The CSI reporting configuration may have a 32-port NZP CSI-RS resource set (for channel measurements). The first sub-configuration (sub-configuration 1) may have a first spatial adaptation mode (spatial adaptation mode 1) and may have a first codebook configuration (codebook configuration 1) of (N1, N2) = (8, 2). The second sub-configuration (sub-configuration 2) may have a second spatial adaptation mode (spatial adaptation mode 2) and may have a second codebook configuration (codebook configuration 2) of (N1, N2) = (8, 1). Additionally, the second sub-configuration may have 16-port NZP CSI-RS resources, where each resource is a subset of the 32-port CSI-RS resources in the CSI-RS resource set and corresponds to a uniform linear array (ULA) of (N1, N2) in codebook 2. The third sub-configuration (sub-configuration 3) may have a third spatial adaptation mode (spatial adaptation mode 3) and may have a third codebook configuration (codebook configuration 3) with (N1, N2) = (4, 1). The third sub-configuration may have 8-port NZP CSI-RS resources, where each resource is a subset of 32-port CSI-RS resources in the CSI-RS resource set and corresponds to a ULA with (N1, N2) in codebook 3. In some cases, the resource subset may be determined at least partially based on the port subset indication. Network node 110 may use the 32-port NZP CSI-RS resources to transmit CSI-RS. UE 120 may measure the 32-port NZP CSI-RS resources and may derive CSI from the measurement. CSI may be associated with at least one resource in the 32-port NZP CSI-RS resources or one or more sub-configurations in the sub-configuration, depending on which sub-configuration is active for CSI reporting. In Type 2 SD adaptation, the CSI report configuration can indicate a set of P-port CSI-RS resources used for channel measurements, and can indicate one or more sub-configurations, where each sub-configuration indicates a set of CSI resource index identifiers corresponding to one or more CSI-RS resources in the P-port CSI-RS resource set. In Type 2 SD adaptation, network node 110 can use each CSI-RS resource indicated by any active sub-configuration in the one or more sub-configurations to transmit CSI-RS.

[0099] In another example, the CSI reporting configuration for Type 1 SD adaptation based on resource grouping can have three sub-configurations. The CSI reporting configuration can have a 32-port NZP CSI-RS resource set (for channel measurements). The first sub-configuration (sub-configuration 1) can have a first spatial adaptation mode (spatial adaptation mode 1) and a first codebook configuration (codebook configuration 1) of (N1, N2) = (8, 2). The second sub-configuration (sub-configuration 2) can have a second spatial adaptation mode (spatial adaptation mode 2) and a second codebook configuration (codebook configuration 2) of (N1, N2) = (8, 1). Additionally, the second sub-configuration can have a 16-port NZP CSI-RS resource set for channel measurements. The third sub-configuration (sub-configuration 3) can have a third spatial adaptation mode (spatial adaptation mode 3) and a third codebook configuration (codebook configuration 3) of (N1, N2) = (4, 1). Additionally, the third sub-configuration can have an 8-port NZP CSI-RS resource set for channel measurements. In some cases, the resources in different sub-configurations may be unrelated.

[0100] In some cases, dynamic adaptation of the power offset values ​​between the PDSCH and CSI-RS can be beneficial for network energy savings. Network nodes may be able to compensate for certain measurements (such as Layer 1 (L1) RSRP and CQI) based on the transmit power difference between the actual power offset and the configured power offset reported by the UE for CSI. This can be beneficial when the transmit power difference is small. However, when the transmit power difference is large, the compensation at the network node may be inaccurate for parameters such as the Rank Indicator (RI) and / or PMI. In some cases, dynamic adaptation of the power offset values ​​between the PDSCH and CSI-RS can be identified according to an example two-step process. In the first step (e.g., step 1), the CSF for adapting the power offset values ​​can be identified. In the second step (e.g., step 2), the PDSCH with the appropriate power offset configuration can be identified. In some cases, configurations of more than one power offset value for the PDSCH relative to the CSI-RS can be supported.

[0101] In some cases, the framework used for power domain (PD) adaptation can be similar to the framework used for spatial domain adaptation as described above (e.g., for type 2 SD). The difference between SD adaptation and PD adaptation can be in sub-configurations, as described below.

[0102] For those with L Individual CSI reporting configurations can enable the UE to report within a single reporting instance. N A CSI framework, in which N CSI and from L Individual configurationN Each sub-configuration is associated (where 1≤ N ≤ L ), and each CSI corresponds to a sub-configuration. N =1 can refer to a single CSI, while N >1 can refer to multiple CSIs.

[0103] As described in Section 5.18.6 of 3GPP Technical Specification (TS) Version 38.321 17, a UE can receive an enable command via MAC-CE for reporting on the Physical Uplink Control Channel (PUCCH). The network can enable and disable configured semi-persistent CSI reporting on the serving cell's PUCCH by transmitting an SP CSI report regarding enabling / disabling the PUCCH MAC-CE. Configurable semi-persistent CSI reporting on the PUCCH can be initially disabled during configuration and after handover. In this case, if the MAC entity receives an SP CSI report regarding enabling / disabling the PUCCH MAC-CE on the serving cell, the MAC entity can indicate information about the SP CSI report regarding enabling / disabling the PUCCH MAC-CE to lower layers. In some cases, the SP CSI on enabling / disabling the PUCCH MAC-CE can be identified by a MAC subheader with a Logical Channel ID (LCID). The MAC subheader may have a serving cell ID field, a bandwidth portion (BWP) ID field, and... Si Fields and reserved bit (R) fields, as described in Section 6.1.3.16, Version 17 of 3GPP TS 38.321.

[0104] In some cases, the UE may receive triggering information for reporting CSI. In other cases, the UE may receive a DCI that instructs the UE to report CSI aperiodically via the Physical Uplink Shared Channel (PUSCH). The triggering state list can be found in the CSI Aperiodic Triggering State List (…). CSI-AperiodicTriggerStateList The trigger state list can be configured in the CSI semi-persistent state list (CSI semi-persistent state list), and each trigger state included in the trigger state list can include a list of associated reporting settings. In some other cases, the UE may receive a DCI instructing the UE to semi-persistently report CSI via PUSCH. CSI-SemiPersistentOnPUSCH-TriggerStateList Configured in the configuration, and each trigger state included in the trigger state list may include a list of associated reporting settings. In some other cases, the UE may receive a MAC-CE instructing the UE to semi-persistently report CSI via PUCCH. In some cases, for UEs with L The CSI reporting configuration can be configured individually, allowing the UE to report in a single reporting instance. N CSI, of which N CSI and fromL Individual configuration N Each sub-configuration is associated (where 1≤ N ≤ L ), and each CSI corresponds to a single sub-configuration.

[0105] As indicated above, Figures 5A to 5B This is provided as an example. Other examples may be provided in conjunction with [the relevant information]. Figures 5A to 5B The descriptions are different.

[0106] Figure 6 This is a diagram illustrating example 600 of a CSI-RS port according to this disclosure. A CSI-RS port may be referred to as a CSI-RS antenna port. CSI-RS ports are indicated by CSI-RS resource configuration and associated with port numbers. The number of CSI-RS ports may be based at least in part on the CSI-RS sequence index, the code division multiplexing (CDM) group size, and the total number of CSI-RS ports. CSI-RS ports are numbered starting from 3000. Specifically, the CSI-RS ports are numbered as {3000, 3001} for 2 CSI-RS ports, {3000, 3001, 3002, 3003} for 4 CSI-RS ports, {3000, 3001, …, 3007} for 8 CSI-RS ports, {3000, 3001, …, 3011} for 12 CSI-RS ports, {3000, 3001, …, 3015} for 16 CSI-RS ports, {3000, 3001, …, 3023} for 24 CSI-RS ports, and {3000, 3001, …, 3031} for 32 CSI-RS ports.

[0107] The UE can use the CSI-RS port number to calculate the CQI of the CSF. For example, the CSI-RS port number allows the UE to identify or assume the antenna relationship between the CSI-RS and the PDSCH. Specifically, for CQI calculation, the UE can assume the following for... v A set of layers [1000, …, 1000+] ν The PDSCH signal on the antenna port in [3000, ..., 3000+] will be generated similarly to the signal on the antenna port in [3000, ..., 3000+]. P The signal equivalent to the corresponding symbol sent on [-1] is as given below. in It is a vector of PDSCH symbols derived from the defined layer mapping, where P is the number of CSI-RS ports, and It is the pre-decoding matrix. If only one CSI-RS port is configured, then W(i) It can be 1 (one). If reporting to CQI... CSI-ReportConfig Higher-level parameters reportQuantity Set as 'cri-RI-PMI-CQI' or 'cri-RI-LI-PMI-CQI' ,but W(i) It can be applicable to x(i) The pre-decoding matrix corresponding to the reported PMI. If the reported CQI... CSI-ReportConfig Higher-level parameters reportQuantity Set as 'cri-RI-CQI' ,but W(i) This can be the pre-decoding matrix corresponding to the process described in Clause 5.2.1.4.2 of 3GPP TS 38.214 Release 17. If the CQI report... CSI-ReportConfig Higher-level parameters reportQuantity Set as 'cri-RI-i1-CQI' According to the process described in Clause 5.2.1.4.2 of 3GPP TS 38.214 version 17, W(i) Is it consistent with the reported i1 The corresponding pre-decoding matrix.

[0108] Reference numeral 605 illustrates the first CSI-RS port configuration corresponding to the first CSI-RS resource. As shown, the first CSI-RS port configuration includes 32 CSI-RS ports ( P = 32), numbered 3000 to 3031. The first CSI-RS resource can be considered as a 32-port NZP CSI-RS resource and can be configured (via a first configuration) in the NZP CSI-RS resource set for channel management with CSI-RS port configuration (N1, N2) = (8, 2), corresponding to 2 columns and 8 rows of CSI-RS ports. Each port in the CSI-RS ports of the first CSI-RS port configuration can be referred to as an active CSI-RS port, since each port in such a CSI-RS port can be measured to calculate CSI using CSI-RS transmitted according to the first CSI-RS port configuration. "Active CSI-RS port" can be used interchangeably with "CSI-RS port used for CSI measurement" herein. CSI-RS resources can be configured for channel measurement, meaning that CSI-RS resources are used to derive the CSI of the channel. Other types of CSI-RS resources may include zero-power CSI-RS resources and CSI-RS resources for interference measurement.

[0109] Reference numeral 610 illustrates a second CSI-RS port configuration that is a subset (e.g., a true subset) of the first CSI-RS port configuration. For example, the second CSI-RS port configuration can be configured via a second configuration using a port subset indication. The port subset indication may include... PA bitmap indicates which CSI-RS ports configured in the first CSI-RS port configuration are active (i.e., used for CSI measurements) in the second CSI-RS port configuration. In this example, the 32-bit bitmap may include the value (1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 0), meaning that CSI-RS ports {3000, 3001, 3002, …, 3007, 3016, 3017, …, 3023} are used for CQI operations. The remaining CSI-RS ports may not be used for CSI measurements or CQI operations, and therefore may be referred to as inactive in this context. The second CSI-RS port configuration may be associated with a second CSI-RS resource, which is associated with the first CSI-RS resource and is a subset of the first CSI-RS resource. "CSI-RS measurement" or "channel measurement" may include acquiring one or more samples at time and / or frequency and / or spatial resources identified by CSI-RS resources. Such samples can then be used to determine the CSI.

[0110] Reference numeral 615 illustrates a third CSI-RS port configuration that is a subset (e.g., a true subset) of the first CSI-RS port configuration. For example, the third CSI-RS port configuration can be configured via a third configuration using a port subset indication. The port subset indication may include... P A bitmap indicates which CSI-RS ports configured in the first CSI-RS port configuration are active in the second CSI-RS port configuration. In this example, the 32-bit bitmap may include the value (0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1), meaning that odd-numbered CSI-RS ports {3001, 3003, 3005, ..., 3015, 3017, 3019, ..., 3031} are used for CQI operations. A third CSI-RS port configuration may be associated with a third CSI-RS resource, which is associated with the first CSI-RS resource and is a subset of the first CSI-RS resource.

[0111] Network node 110 may transmit CSI-RS based on a first CSI-RS resource (referred to as transmitting the first CSI-RS resource). UE 120 may determine CSI by measuring CSI-RS and applying parameters of a second and / or third configuration (e.g., calculating CQI). For example (such as in Type 1 SD adaptation and power domain adaptation), UE 120 may use the CSI-RS transmitted based on the CSI-RS resource to determine the CSI of any active sub-configuration of the CSI-RS resource (or CSI-RS resource set). In some aspects (such as in Type 2 SD adaptation), network node 110 may transmit CSI-RS based on each enabled sub-configuration.

[0112] As indicated above, Figure 6 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 6 The examples described are different.

[0113] Figure 7 These are illustrations of Example 700, an adaptation in the spatial domain, and Example 705, an adaptation in the power domain, according to this disclosure. Example 700 may include CSF reporting (shown by reference numeral 710) and the configuration and / or transmission of a PDSCH with spatial element configuration (shown by reference numeral 715). Example 705 may include CSF reporting (shown by reference numeral 720) and the configuration and / or transmission of a PDSCH with power offset configuration (as shown by reference numeral 725).

[0114] As shown by reference numeral 710, the UE can report CSF. For example, the UE can report CSF to adapt (e.g., enable, disable, reconfigure) spatial elements such as antennas. A network node (e.g., network node 110) can use multiple sub-configurations to configure the CSI reporting configuration. Each sub-configuration can correspond to a CSI-RS antenna port configuration. The UE can measure and report CSI based on all sub-configurations or based on a subset of sub-configurations. For example, the network node can provide an indication of which sub-configurations to report. As shown by reference numeral 715, the network node can send a PDSCH with the appropriate spatial element configuration. For example, the network node can switch between different configurations of active spatial elements based on CSI reports (e.g., CSF) from the UE.

[0115] As shown by reference numeral 720, the UE can report a CSF. For example, the UE can report a CSF to adapt (e.g., enable, disable, reconfigure) a power offset value. A network node (e.g., network node 110) can use multiple sub-configurations to configure the CSI reporting configuration. Each sub-configuration can correspond to a power offset value. The UE can measure and report CSI based on all sub-configurations or based on a subset of sub-configurations. For example, the network node can provide an indication of which sub-configurations to report. As shown by reference numeral 725, the network node can send a PDSCH with an appropriate power offset configuration. For example, the network node can switch between different power offset configurations based on CSI reports (e.g., CSF) from the UE. Communication is sent using a specific power offset relative to another communication or signal (or relative to a baseline power value), or the signal can be referred to as an adaptation in the power domain. In some aspects, for having L The CSI reporting configuration can be configured individually, allowing the UE to report within a single reporting instance. N CSI, of which N CSI and from L (in )of N Each sub-configuration is associated with another, and each CSI corresponds to one sub-configuration.

[0116] It should be noted that spatial domain adaptation can be performed in conjunction with power domain adaptation (e.g., for the same communication). It should also be noted that sub-configurations can be applied to the transmission of CSI-RS from which the CSF described with respect to reference numerals 710 and 720 is derived. For example, a network node can use multiple port or power offsets indicated by the sub-configuration to transmit CSI-RS. Alternatively, a network node can use a baseline CSI-RS resource configuration (e.g., a first CSI-RS resource, a first CSI-RS port configuration, a first power offset) to transmit CSI-RS, and can use a sub-configuration at least in part based on the CSF received by the network node at reference numerals 710 or 720 to transmit the PDSCH shown in reference numerals 715 or 725.

[0117] As indicated above, Figure 7 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 7 The examples described are different.

[0118] The UE can process CSI based on CSI processing metrics (e.g., using CSI-RS measurements to generate CSI). For the purposes of this discussion, two CSI processing metrics are related: Central Processing Unit (CPU) occupancy, which provides a measure of the processing load at the UE; and the number of concurrently active CSI-RS resources and ports, which provides a measure of memory usage. As part of its capability information, the UE reports the number of CPUs it can process simultaneously (via parameters in the component carriers). simultaneousCSI-ReportsPerCC and parameters across all component carriers simultaneousCSI- ReportsAllCC ), which is represented as There is a CPU usage count. This indicates the processing unit currently being used for the ongoing CSI report. At any given time, One unused CPU slot can be used to prepare additional CSI reports. Once no more unused CPU slots are available, the UE will not process any more CSIs. Even when no unused CPU slots are available, the UE can still transmit CSI reports, but for CSI reports exceeding the limit, the UE is allowed to transmit outdated reports. A count is set whenever CSI calculation begins. Increase ,in This is the load specification for the new CSI process. The count is recorded each time a CSI calculation ends. reduce ,in This specifies the load for the completed CSI procedure.

[0119] For non-periodic CSI reports, the CPU is occupied at the end of the last symbol of the PDCCH carrying the CSI trigger, and released at the end of the last symbol of the PUSCH or PUCCH carrying the report. For the first report in a semi-persistent CSI report sequence on a PUSCH, the CPU is occupied at the end of the last symbol of the PDCCH that enabled the CSI procedure, and released at the end of the last symbol of the PUSCH carrying the first report. For periodic and semi-persistent CSI reports, except for the first report in a semi-persistent CSI report sequence on a PUSCH, the CPU is occupied at the latest CSI measurement resource (CSI-RS, CSI-IM, or SSB) available for the report, and released at the end of the last symbol of the PUCCH or PUSCH carrying the report. The latest such CSI-RS resource is formally defined as no later than the latest resource of the so-called CSI reference resource. The timing of the CSI reference resource is defined separately. If multiple CSI-RS resources are used for a given report, and they do not occur simultaneously, the earliest of the multiple CSI-RS resources is counted.

[0120] The UE can also report the maximum number of simultaneously active CSI-RS resources and ports, such as the maximum number of simultaneously active NZP CSI-RS resources per component carrier (via parameters). maxNumberSimultaneousNZP-CSI-RS- PerCC The maximum total number of ports in all simultaneously active NZP CSI-RS resources for each component carrier (via parameter) NumberPortsSimultaneousNZP-CSI-RS-PerCC The maximum number of NZP CSI-RS resources active simultaneously across all component carriers (via parameter) maxNumberSimultaneousNZP-CSI-RS-ActBWP-AllCC ), and the maximum total number of ports in all simultaneously active NZP CSI-RS resources across all component carriers (via parameters totalNumberPortsSimultaneousNZP-CSI-RS-ActBWP-AllCC ).

[0121] For the purpose of determining the number of concurrently active CSI-RS resources, a CSI-RS resource can be considered active according to the following rules: For non-periodic CSI-RS resources, the CSI-RS resource and its ports become active at the end of the last symbol of the PDCCH carrying the CSI trigger, and become inactive at the end of the last symbol of the PUSCH carrying the report. For semi-persistent CSI-RS resources, the CSI-RS resource and its ports become active when the CSI-RS resource is enabled, and become inactive when the CSI-RS resource is disabled. For periodic CSI-RS resources, the CSI-RS resource and its ports become active when the CSI-RS resource is configured, and become inactive when the CSI-RS resource configuration is released.

[0122] In some deployments, if a CSI-RS resource is referenced by one or more CSI report settings... X Then, the CSI-RS resource and the CSI-RS ports within that CSI-RS resource are identified (e.g., counted). X This can be based on the assumption that for each CSI reporting setting that references CSI-RS resources, the CSI-RS resources must be stored in the UE's memory. However, in spatial and power domain adaptations, multiple sub-configurations can be applied to a given CSI-RS resource, and different combinations of these sub-configurations can be active for CSI reporting at a given time. Such different sub-configurations can also indicate different numbers of CSI-RS ports, leading to ambiguity about how CSI-RS resources and CSI-RS ports should be identified (e.g., counted). This ambiguity can result in suboptimal utilization of UE resources, such as memory and processor resources.

[0123] Various aspects of this disclosure generally relate to CSI reporting for spatial domain and / or power domain adaptation. Some aspects more specifically relate to identifying (e.g., counting) active CSI-RS resources and / or ports in conjunction with spatial domain and / or power domain adaptation. In some aspects, the UE may identify (e.g., count) the number of active CSI-RS resources and the number of active CSI-RS ports associated with CSI-RS reporting, wherein CSI-RS is measured according to at least one sub-configuration that includes adaptation (or configuration of CSI-RS resources) with respect to at least one of the power domain or spatial domain.

[0124] Specific aspects of this disclosure can be used to achieve one or more of the following potential advantages. In some aspects, by identifying (e.g., counting) the number of CSI-RS resources and CSI-RS ports associated with a CSI-RS report measured according to at least a sub-configuration, the ambiguity of how CSI-RS resources and ports should be identified (e.g., counted) is reduced. Furthermore, the UE can utilize processor and memory resources more efficiently, and the CSI reporting can be tailored to the complexity of the UE's processor and memory resources.

[0125] Figure 8 This is a diagram of example 800 associated with a CSI-RS resource for a reduced CSI-RS resource identifier (e.g., count), according to this disclosure. Figure 8 As shown, network nodes (e.g., network nodes 110, CU, DU, and / or RU) can communicate with a UE (e.g., UE 120). In some aspects, the network nodes and UEs can be part of a wireless network (e.g., wireless network 100). The UE and network nodes can... Figure 8 The operation shown has been performed with a wireless connection already established.

[0126] As shown by reference numeral 810 in the attached figure, a UE can send a capability report, and a network node can receive the capability report. The capability report can indicate whether the UE supports a feature and / or one or more parameters associated with that feature. For example, capability information can indicate capabilities and / or parameters used to identify (e.g., count) active CSI-RS ports or active CSI-RS resources. One or more operations described herein can be based on the capability information in the capability report. For example, a UE can receive CSI report configurations based on capability information, or can compute new CSI reports only if they do not exceed the UE's capabilities. In some aspects, capability information can be per-UE granularity, per-band granularity, per-band combined granularity, or per-band and per-band combined granularity.

[0127] In some aspects, when configuring or indicating one or more sub-configurations, capabilities can be specific to identifying (e.g., counting) active CSI-RS resources and / or ports. For example, a UE can report its ability to identify (e.g., count) active CSI-RS resources and / or ports. A UE can identify (e.g., count) active CSI-RS resources and / or ports based on its UE capabilities. If a UE does not report this UE capability, the UE can apply the techniques described below to identify (e.g., count) CSI-RS resources and ports.

[0128] As shown by reference numeral 820 in the accompanying drawings, a network node can send, and a UE can receive, a CSI report configuration indicating CSI-RS resources used for channel measurements. The CSI report configuration may also indicate a sub-configuration set, which may be referred to herein as a configuration set. CSI-RS resources used for channel measurements may be compared with CSI-RS resources used for other purposes such as interference measurements. CSI-RS resources may include CSI-RS port configurations indicating the number of CSI-RS ports, as described above. For example, the CSI report configuration may include or indicate a CSI-RS resource configuration (of CSI-RS resources) that indicates a first CSI-RS port configuration, which relates to... Figure 6 This has been described. In some respects, the CSI report configuration indicates the CSI-RS resources used for channel measurements and the CSI-RS resource allocation. L Individual configurations, such as those related to Figure 6 As described. In some aspects, a CSI reporting configuration may include one or more trigger states, or be associated with one or more trigger states (e.g., directly or via a CSI-RS resource). Trigger states may indicate the conditions that trigger the determination and reporting of a CSI report, and may additionally indicate one or more sub-configurations for which a CSI report will be determined and reported. In some aspects, sub-configurations are referred to as configurations.

[0129] In some respects, a CSI report configuration can configure a set of CSI-RS resources for channel measurements. For example, a CSI report configuration can configure multiple CSI-RS resources, each associated with one or more sub-configurations. As another example, a CSI report configuration can configure a first CSI-RS resource and a set of sub-configurations, where each sub-configuration can be used to derive a second CSI-RS resource from the first CSI-RS resource.

[0130] Each sub-configuration in the sub-configuration set can correspond to a CSI-RS transmission setting. For example, CSI-RS can be transmitted or measured based on a sub-configuration in the sub-configuration set, such as by modifying the CSI-RS resource or the CSI report configuration of the CSI-RS resource according to that sub-configuration. Transmission settings can typically indicate CSI-RS port configuration or power offset. For example, transmission settings associated with CSI-RS can indicate the CSI antenna port configuration for Type 1 spatial domain adaptation, the power offset between CSI-RS and SSB for Type 2 spatial domain adaptation, or the power offset between PDSCH and CSI-RS for power domain adaptation.

[0131] As shown by reference numeral 830 in the attached figure, in some aspects, a network node can send, and a UE can receive, an indication of a sub-configuration subset of a sub-configuration set (sometimes referred to as a configuration subset of a configuration set). For example, this indication may include a DCI carrying CSI triggering (which may include an indication of the sub-configuration subset), such as for a non-periodic CSI report or a semi-persistent CSI report on the PUSCH. As another example, the indication may include a MAC-CE that includes an indication of the sub-configuration subset. In some aspects, a UE can provide CSI reports without receiving an indication of the sub-configuration subset. For example, a UE can provide CSI reports for a sub-configuration within a sub-configuration set. In other words, a sub-configuration subset may include all sub-configurations within the sub-configuration set.

[0132] In some aspects, the configuration information and / or capability reports described in conjunction with reference to reference numerals 820 and / or 830 may include information transmitted via multiple communications. Additionally or alternatively, a network node may transmit the configuration information or communications including at least a portion of the configuration information before and / or after the UE transmits the capability report. For example, a network node may transmit a first portion of the configuration information before the capability report, the UE may transmit at least a portion of the capability report, and the network node may transmit a second portion of the configuration information after receiving the capability report. In some aspects, the configuration information may indicate one or more candidate configuration and / or communication parameters. In some aspects, one or more candidate configuration and / or communication parameters may be selected, enabled, and / or disabled by subsequent indications. For example, a subsequent indication may select candidate configuration and / or communication parameters from the one or more candidate configuration and / or communication parameters. In some aspects, subsequent indications (e.g., the indications described herein) may include dynamic indications, such as one or more MAC CEs and / or one or more DCI messages. The UE may configure itself at least in part based on the configuration information. In some aspects, the UE may be configured to perform one or more operations described herein at least in part based on the configuration information.

[0133] As shown by reference numeral 840 in the attached figure, the UE can measure CSI-RS resources. For example, based on the parameters configured in the CSI report, the UE can perform CSI-RS measurements on CSI-RS resources.

[0134] As shown by reference numeral 850 in the attached figure, the UE can determine one or more CSI reports. For example, the UE can use measurements of CSI-RS resources to determine one or more CSI parameters (e.g., CQI, Layer Indicator (LI), or Rank Indicator (RI), etc.). As another example, the UE can determine one or more CSI parameters based on an indicated subset of subconfigurations that references and / or is enabled for CSI-RS resources. As yet another example, the UE can determine one or more CSI parameters based on all subconfigurations in the subconfiguration set.

[0135] The UE can identify (e.g., count) the number of active CSI-RS resources and the number of active CSI-RS ports used for those resources. The number of active CSI-RS resources can indicate how many instances of CSI-RS resources are loaded into the UE's memory. For example, the number of active CSI-RS resources can indicate the memory load at the UE. In some cases, a number of CSI-RS resources can be associated with more than one number of active CSI-RS resources. For example, in some aspects, sub-configurations referencing CSI-RS resources can be identified (e.g., counted) within the number of active CSI-RS resources. The number of active CSI-RS ports can indicate how many CSI-RS ports are active for determining CSI reports of CSI-RS resources. In some aspects, network node configurations may not be allowed to exceed the UE's CSI reporting capabilities.

[0136] In some aspects, the identification (e.g., counting) of the number of active CSI-RS resources and the number of active CSI-RS ports are based at least in part on the CSI-RS resource type, wherein the CSI-RS resource type includes at least one of aperiodic, semi-persistent, or periodic types. This is referred to herein as Method 1. Method 1 may be based at least in part on a subset of subconfigurations, which may be indicated as described above in conjunction with reference to reference numeral 830. For Method 1, the subset of subconfigurations may include M Each sub-configuration, among which MThis is an integer. A subconfiguration subset can reference a CSI-RS resource. For example, a subconfiguration subset can identify a CSI-RS resource, or can be received in the same configuration as the CSI-RS resource. A subconfiguration subset can be used for CSI measurement and reporting. It should be noted that in some respects, a subconfiguration subset can include all subconfigurations within a subconfiguration set. It may be beneficial to identify the number of active CSI-RS resources and CSI-RS ports, at least in part, based on the CSI-RS resource type, because different CSI-RS resource types may occupy CSI processing units in different ways. For example, a non-periodic CSI-RS resource may only occupy CSI processing units between CSI triggering and report sending, while semi-persistent or periodic CSI-RS resources may occupy CSI processing units for longer periods.

[0137] In Method 1, for Type 1 spatial domain adaptation (i.e., when a subset of subconfigurations is associated with an adaptation of logical antenna ports), identifying (e.g., counting) the number of active CSI-RS resources and the number of active CSI-RS ports may include identifying (e.g., counting). M A CSI-RS resource (e.g., when a CSI-RS is referenced by M sub-configurations that can be used for CSI measurement and reporting, the UE can identify (e.g., count) the CSI-RS). M (times) and / or T One CSI-RS port, of which T It is an integer. T It can be based at least in part on the sum of the number of active CSI-RS ports in a subset of subconfigurations (where subconfigurations) s The number of CSI-RS ports is expressed as P s The number of CSI-RS ports configured in the CSI-RS resources (expressed as...) P At least one of the following. For example, T It can be defined as ,in This refers to the number of CSI-RS ports in the CSI-RS resource set configured for channel measurements, and... This refers to the number of CSI-RS ports in the sub-configuration.

[0138] Additionally or alternatively, in method 1, and for type 2 spatial domain adaptation (where the configuration of physical antenna elements of CSI-RS and / or PDSCH is adapted, such as via power offset) or power domain adaptation (where power offset between CSI-RS and PDSCH is implemented), identifying (e.g., counting) the number of active CSI-RS resources and the number of active CSI-RS ports may include identifying (e.g., counting) the configuration in the CSI-RS resources. MThe number of active CSI-RS ports per event.

[0139] As mentioned above, in Method 1, the identifier (e.g., count) can be based at least in part on the CSI-RS resource type. For example, M It can be based at least in part on CSI-RS resource types. For non-periodic CSI-RS (which can be used only for non-periodic CSI reporting), M = N ,in N This refers to the number of sub-configurations for CSI measurement and reporting indicated to the UE via DCI. For semi-persistent or periodic CSI-RS resources, in some respects... M = L ,in L This refers to the number of sub-configurations configured in the CSI report configuration of attached figure 820.

[0140] Alternatively, for semi-persistent or periodic CSI-RS resources, M This can be the number of sub-configurations in the union of the sub-configurations indicated in the trigger states associated with the CSI reporting configuration. For example, consider a CSI reporting configuration indicating semi-persistent or periodic CSI-RS resources used for channel measurements. The CSI reporting configuration can have four sub-configurations numbered 0, 1, 2, and 3. The configuration information shown by reference numeral 820 can indicate three trigger states (e.g., aperiodic trigger states). The first trigger state can be associated with sub-configurations 1, 2, and 3. The second trigger state can be associated with sub-configurations 1 and 2. The third trigger state can be associated with sub-configuration 2. In this example, the union of the sub-configurations indicated in the trigger states can include sub-configurations 1, 2, and 3, therefore... M It is 3.

[0141] In some aspects, the UE may identify (e.g., count) the number of active CSI-RS resources and the number of active CSI-RS ports in a first phase and a second phase (referred to as Method 2). For clarity, these two phases are described separately and in practice may be implemented as a single phase or operation. In some aspects, identifying (e.g., counting) the number of active CSI-RS resources and the number of active CSI-RS ports may include a first phase of identifying (e.g., counting) CSI-RS resources (e.g., identifying (e.g., counting) CSI-RS resources configured in a resource set for channel measurements) and a second phase of identifying (e.g., counting) the number of active CSI-RS resources and the number of active CSI-RS ports associated with a subset of subconfigurations. For example, in the second phase, the UE may identify (e.g., count) CSI-RS resources associated with a subconfiguration. The CSI-RS resources associated with a subconfiguration may include CSI-RS resources configured in a resource set for channel measurements (such as at reference numeral 820) and CSI-RS resources derived from parameters of the subconfiguration.

[0142] In some aspects, identifying (e.g., counting) the number of active CSI-RS resources and the number of active CSI-RS ports associated with a subset of subconfigurations is based at least in part on the CSI-RS resources and the activity time of the CSI-RS ports of the CSI-RS resources. For example, as mentioned, in the second phase, the UE may identify (e.g., count) the CSI-RS resources associated with the subconfiguration. For CSI-RS resources associated with the subconfiguration (e.g., CSI-RS resources configured from the resource set used for channel measurements and CSI-RS resources derived from parameters in the subconfiguration), the activity time may be based at least in part on the CSI-RS resource type of the CSI-RS resources associated with the subconfiguration. Additionally or alternatively, the activity time may be based at least in part on whether the CSI report is an aperiodic CSI report, a semi-persistent CSI report, or a periodic report. Additionally or alternatively, the activity time may be based at least in part on whether the CSI report is transmitted on the PUSCH or the PUCCH.

[0143] The activity period can begin at a start time and end at an end time. The start time is the time when a CSI-RS resource or port becomes active. The end time is the time when a CSI-RS resource or port becomes inactive. For example, for non-periodic or semi-persistent CSI reporting on a PUSCH, the CSI-RS resource and its CSI-RS port (indicated by a port subset indicator) can become active at the end of the last symbol of a PDCCH carrying a DCI with a CSI trigger (which may contain a subset of the indicator subconfiguration subset), and can become inactive at the end of a scheduled PUSCH containing the triggered CSI report. For semi-persistent CSI reporting on a PUCCH, the CSI-RS resource and its CSI-RS port (indicated by a port subset indicator for Type 1 spatial domain adaptation) can become active at the end of a MAC-CE containing a subset of the indicator subconfiguration subset, and can become inactive at the end of a scheduled PUCCH containing the triggered CSI report. For periodic CSI reports, when the corresponding periodic CSI-RS configuration in the CSI-RS resource set used for channel measurements is configured by higher-level signaling (such as RRC signaling at reference 820), the CSI-RS resource and the CSI-RS ports within the CSI-RS resource (indicated by the port subset indication for type 1 spatial domain adaptation) can become active, and when the corresponding periodic CSI-RS configuration is released, they can become inactive.

[0144] In some respects, the subconfiguration subset includes X Each sub-configuration, among which X It is an integer. As described elsewhere in this document, it can be indicated to the UE via DCI or MAC-CE. X A sub-configuration for CSI measurement and reporting. As described elsewhere in this document, X Each sub-configuration can reference CSI-RS resources. In this example, in method 2, the identifier (e.g., count) of the number of CSI-RS resources and the number of CSI-RS ports associated with the sub-configuration subset can include the identifier (e.g., count). Y One CSI-RS resource, of which Y equal X Decrease by 1. For example, CSI-RS resources can be identified (e.g., counted). Y = X - 1 time. In some respects, the number of CSI-RS ports identified (e.g., counted) may include identification (e.g., count). T One CSI-RS port, of which T It is an integer. TIt can be based at least in part on the sum of the number of active CSI-RS ports in a subset of subconfigurations (where subconfigurations) s The number of CSI-RS ports is expressed as P s The number of CSI-RS ports configured in the CSI-RS resources (expressed as...) P ) or the number of sub-configurations for CSI reporting indicated to the UE via DCI or MAC-CE (expressed as N At least one of the following. For example, T It can be defined as ,in This refers to the number of CSI-RS ports in the CSI-RS resource set configured for channel measurements, and... This refers to the number of CSI-RS ports in the sub-configuration. In some respects, N It can be different X ,because X This indicates the number of sub-configurations used for CSI measurement and reporting that reference CSI-RS resources and are indicated via DCI / MAC signaling. N Indicates the number of sub-configurations for CSI reporting indicated to the UE. In some respects, N and X They can be equal.

[0145] In some respects, the UE can determine one or more CSI reports based on a processing timeline. In some respects, the processing timeline can be based at least in part on the number of active CSI-RS resources or the number of active CSI-RS ports. For example, it can be determined by parameter Z or... Z' The defined processing timeline can be increased relative to the baseline of high-complexity CSI reports (or relative to the baseline of fast or low-complexity CSI reports). The baseline for high-complexity CSI reports is shown in Table 1. Z It can indicate the minimum time between the end of the PDCCH that triggers a non-periodic CSI-RS report and the PUSCH that carries the CSI derived from the CSI-RS, or the minimum time between the end of the PDCCH that carries the PUSCH for periodic or semi-persistent CSI-RS scheduling and the PUSCH. Z' It can indicate the minimum time between the CSI-RS and the PUSCH or PUCCH of the CSI carrying the CSI-RS.

[0147] Table 1

[0148] As shown by reference numeral 860 in the attached figure, the UE may send one or more CSI reports. For example, the UE may send one or more CSI reports via PUCCH or PUSCH. One or more CSI reports may include one or more CSI parameters associated with a subset of subconfigurations, such as a true subset of the subconfiguration set or all subconfigurations in the subconfiguration set.

[0149] As indicated above, Figure 8 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 8 The examples described are different.

[0150] Figures 9 to 11 Examples of active CSI-RS ports and active CSI-RS resources are illustrated according to the identification (e.g., counting) of this disclosure. Figures 9 to 11 In this configuration, CSI reporting setups (such as those indicated by reference numeral 820) can have 32 CSI-RS ports. For example, it can be represented as... k The 32-port NZP CSI-RS resource can be configured using (8, 2) CSI-RS port configurations (N1, N2) within the NZP CSI-RS resource set used for channel measurements, as described elsewhere in this document. The CSI report configuration can also (implicitly or explicitly) indicate a set of four sub-configurations: Subconfiguration 0 (32 CSI-RS ports): (N1, N2) = (8, 2), and the port subset indicator includes a 32-bit bitmap of all ones, or the port subset indicator can be skipped.

[0151] Sub-configuration 1 (16 CSI-RS ports): (N1, N2) = (4, 2), and a port subset indication including a 32-bit bitmap (1 1 1 1 1 1 1 1 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 0 0), which means that CSI-RS ports {3000, 3001, 3002, …, 3007, 3016, 3017, …, 3023} are used for CQI operations.

[0152] Sub-configuration 2 (16 CSI-RS ports): (N1, N2) = (8, 1), and a port subset indication including a 32-bit bitmap (0 1 0 1 01 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1), which means that odd-numbered CSI-RS ports {3001, 3003, 3005, …, 3015, 3017, 3019, …, 3031} are used for CQI operations.

[0153] Sub-configuration 3 (8 CSI-RS ports): (N1, N2) = (4, 1), and a port subset indication including a 32-bit bitmap (0 1 0 1 01 0 1 0 0 0 0 0 0 0 0 1 0 1 0 1 0 1 0 0 0 0 0 0 0 0), which means that odd-numbered CSI-RS ports {3001, 3003, 3005, 3007, 3017, 3019, 3021, 3023} are used for CQI operations.

[0154] In some respects, one or more of the four sub-configurations may also indicate power domain adaptation and / or type 2 space domain adaptation.

[0155] Figure 9 This is an illustration of example 900 where sub-configuration 0 and sub-configuration 1 are active. As shown by reference numeral 905, the UE can receive the configuration and / or activation of CSI-RS resource k at a first time. As shown by reference numeral 910, the UE can receive the release and / or deactivation of CSI-RS resource k at a second time. As shown by reference numeral 915, the UE can receive dynamic signaling (e.g., DCI or MAC-CE) that triggers CSI reporting and indicates sub-configurations 0 and 1 at a third time. Therefore, CSI reports can be aperiodic or semi-persistent CSI reports. As shown by reference numeral 920, the end of a PUSCH or PUCCH carrying one or more CSI reports can occur at a fourth time.

[0156] As shown by reference numeral 925, when a sub-configuration is inactive, the number of active CSI-RS resources is identified (e.g., counted) as 1, and the number of active CSI-RS ports for the CSI-RS resources is identified (e.g., counted) as 32. This can include a first-stage counting, as described above. Reference numeral 930 shows the active time for sub-configurations 0 and 1. As shown, during the active time, the number of active CSI-RS resources is identified (e.g., counted) as 2, and the number of active CSI-RS ports is identified (e.g., counted) as 48 (e.g., in a second-stage counting). In this example, the number of active CSI-RS resources is 2, not 3, because the UE can reuse the representation for sub-configuration 0. k The memory of the CSI-RS resources, which is represented as k The CSI-RS resources are the same. In this case, the UE may not reuse memory for sub-configuration 1, so sub-configuration 1 is still counted separately. For example, for those that can be used for CSI measurement and reporting... M (2) For each activity sub-configuration, CSI-RS resources can be identified (e.g., counted). M In some respects, CSI-RS resources can be identified (e.g., counted) once in the first phase and can be identified (e.g., counted) again in the second phase. Y = X - 1) Once. Furthermore, the number of active CSI-RS ports can be identified (e.g., counted) as... T = 48, because P (combined) Figure 8 The value (as described) equals 32, and is available across all active sub-configurations. P s The sum equals 48 (it is determined to be 16 + 32). P and P s The maximum sum is 48.

[0157] As indicated above, Figure 9 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 9 The examples described are different.

[0158] Figure 10This is an illustration of example 1000 where sub-configuration 1 and sub-configuration 3 are active. As shown by reference numeral 1005, the UE can receive the configuration and / or activation of CSI-RS resource k at a first time. As shown by reference numeral 1010, the UE can receive the release and / or deactivation of CSI-RS resource k at a second time. As shown by reference numeral 1015, the UE can receive dynamic signaling (e.g., DCI or MAC-CE) that triggers CSI reporting and indicates sub-configurations 1 and 3 at a third time. Therefore, CSI reports can be non-periodic or semi-persistent CSI reports with periodic or semi-persistent CSI-RS. As shown by reference numeral 1020, the end of a PUSCH or PUCCH carrying one or more CSI reports can occur at a fourth time.

[0159] As shown by reference numeral 1025, when a sub-configuration is inactive, the number of active CSI-RS resources is identified (e.g., counted) as 1, and the number of active CSI-RS ports for the CSI-RS resources is identified (e.g., counted) as 32. This can include a first-stage counting, as described above. Reference numeral 1030 shows the active time for sub-configurations 1 and 3. As shown, during the active time, the number of active CSI-RS resources is identified (e.g., counted) as 2, and the number of active CSI-RS ports is identified (e.g., counted) as 32 (e.g., in a second-stage counting). In this example, the number of active CSI-RS resources is 2, not 3, because the UE can reuse the representation for either sub-configuration 1 or 3. k The storage of CSI-RS resources. For example, for those that can be used for CSI measurements and reporting. M (2) For each activity sub-configuration, CSI-RS resources can be identified (e.g., counted). M In some respects, CSI-RS resources can be identified (e.g., counted) once in the first phase and can be identified (e.g., counted) again in the second phase. Y = X - 1) Once. Furthermore, the number of active CSI-RS ports can be identified (e.g., counted) as... T = 32, because P (combined) Figure 8 The value (as described) equals 32, and is available across all active sub-configurations. P s The sum equals 24 (it is determined to be 16 + 8). P and P s The maximum value of the sum is 32.

[0160] As indicated above, Figure 10 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 10 The examples described are different.

[0161] Figure 11 This is an illustration of example 1100 where sub-configuration 1 and sub-configuration 2 are active. As shown by reference numeral 1105, the UE can receive CSI-RS resources at the first moment. k Configuration and / or enabling. Configuration and / or enabling can also indicate sub-configurations 1 and 2. As shown by reference numeral 1110 in the attached figure, the UE can receive CSI-RS resources in a second time. k Release and / or deactivation. Therefore, Example 1100 can exemplify periodic CSI reporting with activity sub-configurations 1 and 2.

[0162] As shown by reference numeral 1115, during the active time defined by reference numerals 1100 and 1105, the number of active CSI-RS resources is identified (e.g., counted) as 2, and the number of active CSI-RS ports is identified (e.g., counted) as 32 (e.g., in the second-phase counting). In this example, the number of CSI-RS resources is 2, not 3, because the UE can reuse the representation for either sub-configuration 1 or 2. k The storage of CSI-RS resources. For example, for those that can be used for CSI measurements and reporting. M (2) For each activity sub-configuration, CSI-RS resources can be identified (e.g., counted). M Furthermore, the number of CSI-RS ports can be identified (e.g., counted) as... T = 32, because P (combined) Figure 8 The value (as described) equals 32, and is available across all active sub-configurations. P s The sum equals 32 (which is determined to be 16 + 16). P and P s The maximum value of the sum is 32.

[0163] As indicated above, Figure 11 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 11 The examples described are different.

[0164] Figure 12 This is a diagram illustrating an example process 1200 performed, for example, at a UE or a device of a UE, according to this disclosure. Example process 1200 is an example in which a device or UE (e.g., UE 120) performs operations associated with techniques for identifying (e.g., counting) channel state information reference signal resources for spatial or power domain adaptation.

[0165] like Figure 12As shown, in some aspects, process 1200 may include receiving a CSI report configuration indicating CSI-RS resources and a set of sub-configurations for channel measurements, wherein each sub-configuration in the set corresponds to a CSI-RS transmission setting (block 1210). For example, the UE (e.g., using...) Figure 13 The receiving component 1302 and / or communication manager 1306 depicted herein can receive a CSI report configuration indicating CSI-RS resources and a set of sub-configurations for channel measurements, wherein each sub-configuration in the set corresponds to a CSI-RS transmission setting, as described above. In some aspects, a sub-configuration is referred to as a configuration. The transmission setting may relate to at least one of (e.g., identifying) a CSI-RS port configuration or a CSI-RS power offset. In some aspects, the number of active CSI-RS resources and / or the number of active CSI-RS ports may be based at least in part on the CSI-RS resource type.

[0166] like Figure 12 Further shown, in some aspects, process 1200 may include identifying (e.g., counting) the number of active CSI-RS resources and the number of active CSI-RS ports used for those CSI-RS resources, wherein the number of active CSI-RS resources and the number of active CSI-RS ports correspond to a configuration subset of a configuration set, and are at least partially based on the CSI-RS resource type, wherein the CSI-RS resource type includes at least one of aperiodic, semi-persistent, or periodic types (box 1220). For example, a UE (e.g., using...) Figure 13 The described communication manager 1306 can identify (e.g., count) the number of active CSI-RS resources and the number of active CSI-RS ports for those CSI-RS resources, wherein the number of active CSI-RS resources and the number of active CSI-RS ports correspond to a configuration subset of the configuration set and are based at least in part on the CSI-RS resource type, as described above.

[0167] like Figure 12 As further shown, in some aspects, process 1200 may include sending one or more CSI reports based on a subset of a sub-configuration set (box 1230). For example, the UE (e.g., using...) Figure 13 The sending component 1304 and / or communication manager 1306 described above can send one or more CSI reports based on a subset of the subconfiguration set.

[0168] Process 1200 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.
