DETAILED DESCRIPTION

[0016] Generally, the present disclosure describes systems, methods, and apparatuses for techniques for CSI measurement and reporting. In certain embodiments, the methods may be performed using computer code embedded on a computer-readable medium. In certain embodiments, an apparatus or system may include a computer-readable medium containing computer-readable code which, when executed by a processor, causes the apparatus or system to perform at least a portion of the below described solutions.

[0017] In one embodiment, the subject matter herein describes techniques to improve network energy savings for a network, e.g., a gNB and a UE in terms of base station (“BS”) transmission and reception, which may include, without precluding other techniques, how to achieve more efficient operation dynamically and/or semi-statically and finer granularity adaptation of transmissions and/or receptions in one or more of network energy saving techniques in time, frequency, spatial, and power domains, with potential support/feedback from UE, and potential UE assistance information and information exchange/coordination over network interfaces.

[0018] For a network entity operating with multiple antenna panels or multiple transmission and reception points (“TRPs”), it may be more efficient to dynamically turn on/off a certain antenna panel or TRP (or dynamically switch a state of an antenna panel or TRP between in an active state and in an inactive state) based on traffic conditions to reduce energy consumption. To support such features without impacting user throughput or other performance (e.g., latency), the network entity should be able to properly select an active antenna panel or TRP at a given time.

[0019] This disclosure presents techniques for CSI measurement and reporting to facilitate efficient selection and dynamic turning on/off of an antenna panel or TRP by a network entity. In one embodiment, a UE receives a CSI report configuration including a plurality of channel measurement resource configurations and indicating reference signal received power (“RSRP”) or signal-to -noise and interference ratio (“SINR”) measurement and reporting for each of the plurality of channel measurement resource configurations. The UE performs measurements on resources configured by the plurality of channel measurement resource configurations and reports a configured number of resource indices and corresponding RSRP or SINR values for each channel measurement resource configuration.

[0020] In one embodiment, if a UE is configured with groupBasedBeamReporting-rl8 set to ‘enabled’, the UE reports in a single reporting instance a first number of group(s) of two CSI reference signal (“CSI-RS”) resource indicators (“CRIs”) or synchronization signal (“SS”)/physical broadcast channel (“PBCH”) resource block indicators (“SSBRIs”) selecting one CSI-RS or SSB from each of two CSI resource sets, where CSI-RS and/or SSB resources of each group may be received simultaneously by the UE, and a second number of CRI(s) or SSBRI(s) for another CSI resource set not associated with the largest measured value of layer 1 (“L1”)-RSRP for each report setting.

[0021] In one embodiment, when the higher layer parameter groupBasedBeamReporting- rl 7 in CSI-ReportConfig is configured, a UE reports a configured number of groups of two CRIs or SSBRIs selecting one CSI-RS or SSB from each of two CSI resource sets for a report setting, where CSI-RS and/or SSB resources of each group can be received simultaneously by the UE; however, in such an embodiment, a UE may not report the best N beams for each TRP/antenna panel independently.

[0022] In the proposed solution described herein, a UE may report the best N number of beams independently for each TRP or gNB antenna panel with or without group reporting in each report setting, when multiple CSI resource sets corresponding to multiple TRPs/antenna panels are configured in each report setting. These new reporting settings allow gNB to dynamically switch between single TRP/antenna panel transmission and multi-TRP/antenna panel transmission and to properly select its active antenna panel(s) or TRP(s) at a given time while maintaining same or similar configuration signaling overhead and measurement time compared to Rel-17 group based beam reporting.

[0023] Figure 1 depicts a wireless communication system 100 supporting techniques for CSI measurement and reporting, according to embodiments of the disclosure. In one embodiment, the wireless communication system 100 includes at least one remote unit 105, a radio access network (“RAN”) 120, and a mobile core network 140. The RAN 120 and the mobile core network 140 form a mobile communication network. The RAN 120 may be composed of a base unit 110 with which the remote unit 105 communicates using wireless communication links 115. Even though a specific number of remote units 105, base units 110, wireless communication links 115, RANs 120, and mobile core networks 140 are depicted in Figure 1, one of skill in the art will recognize that any number of remote units 105, base units 110, wireless communication links 115, RANs 120, and mobile core networks 140 may be included in the wireless communication system 100.

[0024] In one implementation, the RAN 120 is compliant with the 5G system specified in the 3GPP specifications. In another implementation, the RAN 120 is compliant with the LTE system specified in the 3GPP specifications. More generally, however, the wireless communication system 100 may implement some other open or proprietary communication network, for example WiMAX, among other networks. The present disclosure is not intended to be limited to the implementation of any particular wireless communication system architecture or protocol.

[0025] In one embodiment, the remote units 105 may include computing devices, such as desktop computers, laptop computers, personal digital assistants (“PDAs”), tablet computers, smart phones, smart televisions (e.g., televisions connected to the Internet), smart appliances (e.g., appliances connected to the Internet), set-top boxes, game consoles, security systems (including security cameras), vehicle on-board computers, network devices (e.g., routers, switches, modems), or the like. In some embodiments, the remote units 105 include wearable devices, such as smart watches, fitness bands, optical head-mounted displays, or the like. Moreover, the remote units 105 may be referred to as the UEs, subscriber units, mobiles, mobile stations, users, terminals, mobile terminals, fixed terminals, subscriber stations, user terminals, wireless transmit/receive unit (”WTRU”), a device, or by other terminology used in the art.

[0026] The remote units 105 may communicate directly with one or more of the base units 110 in the RAN 120 via uplink (“UL”) and downlink (“DL”) communication signals. Furthermore, the UL and DL communication signals may be carried over the wireless communication links 115. Here, the RAN 120 is an intermediate network that provides the remote units 105 with access to the mobile core network 140.

[0027] In some embodiments, the remote units 105 communicate with an application server 151 via a network connection with the mobile core network 140. For example, an application 107 (e.g., web browser, media client, tclephonc/VoIP application) in a remote unit 105 may trigger the remote unit 105 to establish a PDU session (or other data connection) with the mobile core network 140 via the RAN 120. The mobile core network 140 then relays traffic between the remote unit 105 and the application server 151 in the packet data network 150 using the PDU session. Note that the remote unit 105 may establish one or more PDU sessions (or other data connections) with the mobile core network 140. As such, the remote unit 105 may concurrently have at least one PDU session for communicating with the packet data network 150 and at least one PDU session for communicating with another data network (not shown).

[0028] The base units 110 may be distributed over a geographic region. In certain embodiments, a base unit 110 may also be referred to as an access terminal, an access point, a base, a base station, a Node-B, an eNB, a gNB, a Home Node-B, a relay node, a RAN node, or by any other terminology used in the art. The base units 110 are generally part of a radio access network (“RAN”), such as the RAN 120, that may include one or more controllers communicably coupled to one or more corresponding base units 110. These and other elements of radio access network are not illustrated but are well known generally by those having ordinary skill in the art. The base units 110 connect to the mobile core network 140 via the RAN 120.

[0029] The base units 110 may serve a number of remote units 105 within a serving area, for example, a cell or a cell sector, via a wireless communication link 115. The base units 110 may communicate directly with one or more of the remote units 105 via communication signals. Generally, the base units 110 transmit DU communication signals to serve the remote units 105 in the time, frequency, and/or spatial domain. Furthermore, the DU communication signals may be carried over the wireless communication links 115. The wireless communication links 115 may be any suitable carrier in licensed or unlicensed radio spectrum. The wireless communication links 115 facilitate communication between one or more of the remote units 105 and/or one or more of the base units 110. Note that the base unit 110 and the remote unit 105 may communicate over unlicensed radio spectrum.

[0030] In one embodiment, the mobile core network 140 is a 5G core (“5GC”) or the evolved packet core (“EPC”), which may be coupled to a packet data network 150, like the Internet and private data networks, among other data networks. A remote unit 105 may have a subscription or other account with the mobile core network 140. Each mobile core network 140 belongs to a single public land mobile network (“PLMN”). The present disclosure is not intended to be limited to the implementation of any particular wireless communication system architecture or protocol.

[0031] The mobile core network 140 includes several network functions (“NFs”). As depicted, the mobile core network 140 includes multiple user plane functions (“UPFs”) 141. The mobile core network 140 also includes multiple control plane functions including, but not limited to, an Access and Mobility Management Function (“AMF”) 143 that serves the RAN 120, a Session Management Function (“SMF”) 145, an Authentication Server Function (“AUSF”) 147, and a Unified Data Management function (“UDM”) 149. In certain embodiments, the mobile core network 140 may also include a Policy Control Function (“PCF”), a Network Repository Function (“NRF”) (used by the various NFs to discover and communicate with each other over APIs), or other NFs defined for the 5GC.

[0032] In various embodiments, the mobile core network 140 supports different types of mobile data connections and different types of network slices, wherein each mobile data connection utilizes a specific network slice. Here, a “network slice” refers to a portion of the mobile core network 140 optimized for a certain traffic type or communication service. A network instance may be identified by a S-NSSAI, while a set of network slices for which the remote unit 105 is authorized to use is identified by NS SAI. In certain embodiments, the various network slices may include separate instances of network functions, such as the SMF 145 and UPF 141. In some embodiments, the different network slices may share some common network functions, such as the AMF 143. The different network slices are not shown in Figure 1 for ease of illustration, but their support is assumed.

[0033] Although specific numbers and types of network functions are depicted in Figure 1 , one of skill in the art will recognize that any number and type of network functions may be included in the mobile core network 140. Moreover, where the mobile core network 140 is an EPC, the depicted network functions may be replaced with appropriate EPC entities, such as an MME, S-GW, P-GW, HSS, and the like. In certain embodiments, the mobile core network 140 may include a AAA server. In various embodiments, the remote units 105 may communicate directly with each other (e.g., device-to-device communication) using sidelink (“SL”) communication signals 117.

[0034] While Figure 1 depicts components of a 5G RAN and a 5G core network, the described embodiments apply to other types of communication networks and RATs, including IEEE 802.11 variants, GSM, GPRS, UMTS, LTE variants, CDMA 2000, Bluetooth, ZigBee, Sigfoxx, and the like. For example, in an LTE variant involving an EPC, the AMF 141 may be mapped to an MME, the SMF mapped to a control plane portion of a PGW and/or to an MME, the UPF map to an SGW and a user plane portion of the PGW, the UDM/UDR maps to an HSS, etc.

[0035] In the following descriptions, the term “gNB” is used for the base station but it is replaceable by any other radio access node, e.g., RAN node, eNB, BS, eNB, gNB, AP, NR, etc. Further the operations are described mainly in the context of 5G NR.

[0036] In Rel-17 3GPP New Radio (“NR”), when the higher layer parameter groupBasedBeamReporting-r!7 in CSI-ReportConfig is configured, a UE reports a configured number of groups of two CRIs or SSBRIs selecting one CSI-RS or SSB from each of two CSI resource sets for a report setting, where CSI-RS and/or SSB resources of each group can be received simultaneously by the UE. The UE indicates the CSI resource set associated with the largest measured value of Ll-RSRP, and for each group, CRI or SSBRI of the indicated CSI resource set is present first.

[0037] Further, in Rel-17 NR, a UE may be configured to report up to three CRIs in one reporting instance - (1) a first CRI indicating a resource pair, corresponding two rank indicator (“RIs”), precoding matrix indicators (“PMIs”), and layer indicators (“Lis”) for Resource Group 1 and Resource Group 2, respectively, and one channel quality indicator (“CQI”) for non-coherent joint transmission (“NCJT”); (2) a second CRI for Resource Group 1, corresponding one RI/PMI/LI, and one or two CQIs; and (3) a third CRI for Resource Group 2, corresponding one RI/PMI/LI, and one or two CQIs.

[0038] In one embodiment, according to TS 38.214 (incorporated herein by reference), each CSI resource setting CSI-ResourceConfig contains a configuration of a list of S>1 CSI resource sets (given by higher layer parameter csi-RS-ResourceSetList), where the list is comprised of references to either or both of non-zero power (“NZP”) CSI- RS resource set(s) and SSB set(s) or the list is comprised of references to CSI-interference measurement (“IM”) resource set(s). Each CSI resource setting may be located in the downlink (“DL”) bandwidth part (“BWP”) identified by the higher layer parameter B WP-id, where CSI resource settings linked to a CSI report setting have the same DL BWP.

[0039] In one embodiment, the time domain behavior of the CSI-RS resources within a CSI resource setting are indicated by the higher layer parameter resourceType and can be set to aperiodic, periodic, or semi-persistent. For periodic and semi-persistent CSI resource settings, in one embodiment, when the UE is configured with groupBasedBeamReporting-rl 7, the number of CSI resource sets configured is S=2, otherwise the number of CSI-RS Resource sets configured is limited to S=l . For periodic and semi-persistent CSI resource settings, in one embodiment, the configured periodicity and slot offset is given in the numerology of its associated DL BWP, as given by BWP -id. In one embodiment, when a UE is configured with multiple CSI- ResourceConfigs consisting of the same NZP CSI-RS resource ID, the same time domain behavior shall be configured for the CSI-ResourceConfigs . In one embodiment, when a UE is configured with multiple CSI-ResourceConfigs consisting of the same CSI-IM resource ID, the same timedomain behavior shall be configured for the CSI-ResourceConfigs . In one embodiment, CSI resource settings linked to a CSI report setting have the same time domain behavior.

[0040] The following are configured via higher layer signaling for one or more CSI resource settings for channel and interference measurement - CSI-IM resource for interference measurement, NZP CSI-RS resource for interference measurement, and NZP CSI-RS resource for channel measurement.

[0041] In one embodiment, the UE assumes that the NZP CSI-RS resource(s) for channel measurement and the CSI-IM resource(s) for interference measurement configured for one CSI reporting are resource-wise quasi -co-located (“QCLed”) with respect to 'typeD'. When a NZP CSI- RS resource(s) is used for interference measurement, in one embodiment, the UE may assume that the NZP CSI-RS resource for channel measurement and the CSI-IM resource or NZP CSI-RS resource(s) for interference measurement configured for one CSI reporting are QCLed with respect to 'typeD'.

[0042] For Ll-SINR measurement, when one resource setting is configured, the resource setting (given by higher layer parameter resource sForChannelMeasurement) is for channel and interference measurement on NZP CSI-RS for Ll-SINR computation. The UE may assume that same 1 port NZP CSI-RS resource(s) with density three resource elements (“Res”) per resource block (“RB”) is used for both channel and interference measurements.

[0043] In one embodiment, when two resource settings are configured, the first resource setting (given by higher layer parameter resourcesForChannelMeasurement) is for channel measurement on SSB or NZP CSI-RS and the second one (given by either higher layer parameter csi-IM-ResourcesForlnterference or higher layer parameter nzp-CSI-RS- ResourcesForlnterference)' is for interference measurement performed on CSI-IM or on 1 port NZP CSI-RS with density three REs/RB, where each SSB or NZP CSI-RS resource for channel measurement is associated with one CSI-IM resource or one NZP CSI-RS resource for interference measurement by the ordering of the SSB or NZP CSI-RS resource for channel measurement and CSI-IM resource or NZP CSI-RS resource for interference measurement in the corresponding resource sets. The number of SSB(s) or CSI-RS resources for channel measurement equals the number of CSI-IM resources or the number of NZP CSI-RS resource for interference measurement.

[0044] In one embodiment, the UE may apply the SSB, or 'typeD' RS configured with qcl- Type set to 'typeD' to the NZP CSI-RS resource for channel measurement, as the reference RS for determining 'typeD' assumption for the corresponding CSI-IM resource or the corresponding NZP CSI-RS resource for interference measurement configured for one CSI reporting.

[0045] In one embodiment, the UE may expect that the NZP CSI-RS resource set for channel measurement and the NZP-CSI-RS resource set for interference measurement, if any, are configured with the higher layer parameter repetition. [0046] For aperiodic CSI, and for periodic and semi-persistent CSI resource settings, , in one embodiment, if groupBasedBeamReporting-rl 7 is configured, each trigger state configured using the higher layer parameter CSI-AperiodicTriggerState is associated with one or multiple CSI-ReportConfig where each CSI-ReportConfig is linked to periodic or semi-persistent, setting(s).

[0047] In one embodiment, when one resource setting is configured, the resource setting is given by resourcesForChannelMeasurement for Ll-RSRP measurement. In such a case, the number of configured CSI resource sets in the resource setting is S=2.

[0048] For aperiodic CSI, and for aperiodic CSI resource settings, in one embodiment, if groupBasedBeamReporting-rl 7 is configured, each trigger state configured using the higher layer parameter CSI-AperiodicTriggerState is associated with resourcesForChannel and resourcesForChannel2 , which correspond to first and second resource sets, respectively, for Ll- RSRP measurement.

[0049] For semi-persistent or periodic CSI, in one embodiment, each CSI-ReportConfig is linked to periodic or semi -persistent Resource setting(s). In one embodiment, when one resource setting (given by higher layer parameter resourcesForChannelMeasurement) is configured, the resource setting is for channel measurement for Ll-RSRP or for channel and interference measurement for Ll-SINR computation.

[0050] In one embodiment, when two resource settings are configured, the first resource setting (given by higher layer parameter resourcesForChannelMeasurement) is for channel measurement and the second resource setting (given by higher layer parameter csi-IM- ResourcesForlnterference) is used for interference measurement performed on CSI-IM. For Ll- SINR computation, the second resource setting (given by higher layer parameter csi-IM- ResourcesForlnterference or higher layer parameter nzp-CSI-RS-ResourceForlnterference) is used for interference measurement performed on CSI-IM or on NZP CSI-RS.

[0051] In one embodiment, a UE is not expected to be configured with more than 64 NZP CSI-RS resources and/or SS/PBCH block resources in resource setting for channel measurement for a CSI-ReportConfig with the higher layer parameter reportQuantity set to 'none', 'cri-RI-CQI', 'cri-RSRP', 'ssb-Index-RSRP', 'cri-SINR' or 'ssb-Index-SINR', 'cri-RSRP-Capability[Set]Index', 'ssb-Index-RSRP-Capability[Set]Index', 'cri-SINR-Capability[Set]Index' or 'ssb-Index-SINR- Capability [Set]Index' .

[0052] In one embodiment, if interference measurement is performed on CSI-IM, each CSI-RS resource for channel measurement is resource-wise associated with a CSI-IM resource by the ordering of the CSI-RS resource and CSI-IM resource in the corresponding resource sets. The number of CSI-RS resources for channel measurement equals to the number of CSI-IM resources.

[0053] In one embodiment, an NZP CSI-RS resource set for channel measurement with 2 < K_s < 8 resources can be configured with two Resource Groups, with K_± > 1 resources in Group 1 and K₂ > 1 resources in Group 2, such that K_r + K₂ = K_s, and with N G {1,2} resource pairs. Each resource pair consists of one resource from Group 1 and one resource from Group 2. The same resource can be associated with two resource pairs in frequency range 1 but not in frequency range 2.

[0054] Except for Ll-SINR, in one embodiment, if interference measurement is performed on NZP CSI-RS, a UE does not expect to be configured with more than one NZP CSI-RS resource in the associated resource set within the resource setting for channel measurement. Except for Ll- SINR, the UE configured with the higher layer parameter nzp-CSI-RS-ResourcesForlnterference may expect no more than 18 NZP CSI-RS ports configured in a NZP CSI-RS resource set.

[0055] For CSI measurement(s) other than Ll-SINR, in one embodiment, a UE assumes each NZP CSI-RS port configured for interference measurement corresponds to an interference transmission layer; interference transmission layers on NZP CSI-RS ports for interference measurement take into account the associated EPRE ratios configured in 5.2.2.3.1 (incorporated herein by reference); and other interference signal on REs of NZP CSI-RS resource for channel measurement, NZP CSI-RS resource for interference measurement, or CSI-IM resource for interference measurement.

[0056] For Ll-SINR measurement with dedicated interference measurement resources, in one embodiment, a UE assumes the total received power on dedicated NZP CSI-RS resource for interference measurement or dedicated CSI-IM resource for interference measurement corresponds to interference and noise.

[0057] For Ll-RSRP computation, in one embodiment, the UE may be configured with CSI-RS resources, SS/PBCH Block resources or both CSI-RS and SS/PBCH block resources, when resource-wise quasi co-located with 'type C and 'typeD' when applicable. In one embodiment, the UE may be configured with CSI-RS resource setting up to 16 CSI-RS resource sets having up to 64 resources within each set. The total number of different CSI-RS resources over all resource sets is no more than 128.

[0058] For Ll-RSRP reporting, in one embodiment, if the higher layer parameter nrofReportedRS in CSI-ReportConfig is configured to be one, the reported Ll-RSRP value is defined by a 7-bit value in the range [-140, -44] dBm with IdB step size, if the higher layer parameter nrofReportedRS is configured to be larger than one, or if the higher layer parameter groupBasedBeamReporting is configured as 'enabled', or if the higher layer parameter groupBasedBeamReporting-rl7 is configured, the UE shall use differential Ll-RSRP based reporting, where the largest measured value of Ll-RSRP is quantized to a 7 -bit value in the range [-140, -44] dBm with IdB step size, and the differential Ll-RSRP is quantized to a 4-bit value. The differential Ll-RSRP value is computed with 2 dB step size with a reference to the largest measured Ll-RSRP value which is part of the same Ll-RSRP reporting instance. The mapping between the reported Ll-RSRP value and the measured quantity is described in TS 38.133 (incorporated herein by reference).

[0059] When the higher layer parameter groupBasedBeamReporting-r!7 in CSI- ReportConfig is configured, in one embodiment, the UE shall indicate the CSI resource set associated with the largest measured value of Ll-RSRP, and for each group, CRI or SSBRI of the indicated CSI resource set is present first.

[0060] If the higher layer parameter timeRestrictionForChannelMeasurements in CSI- ReportConfig is set to "noi 'onfigiired". in one embodiment, the UE shall derive the channel measurements for computing Ll-RSRP value reported in uplink slot n based on only the SS/PBCH or NZP CSI-RS, no later than the CSI reference resource, (defined in TS 38.211, which is incorporated herein by reference) associated with the CSI resource setting.

[0061] If the higher layer parameter timeRestrictionForChannelMeasurements in CSI- ReportConfig is set to "('onfigiirecr'. in one embodiment, the UE shall derive the channel measurements for computing Ll-RSRP reported in uplink slot n based on only the most recent, no later than the CSI reference resource, occasion of SS/PBCH or NZP CSI-RS (defined in TS 38.211) associated with the CSI resource setting.

[0062] When the UE is configured with NumberOfAdditionalPCI, in one embodiment, a CSI-SSB-ResourceSet configured for Ll-RSRP reporting includes one or more sets of SSB indices where PCI indices are associated with the sets of SSB indices, respectively.

[0063] When the UE is configured with a CSI-ReportConfig with the higher layer parameter reportQuantity set to 'cri-RSRP-Capability[Set]Index' or 'ssb-Index-RSRP- Capability[Set]Index', in one embodiment, an index of UE capability value set, indicating the maximum supported number of SRS antenna ports, is reported along with the pair of SSBRI/CRI and Ll-RSRP.

[0064] Lor Ll-SINR computation, for channel measurement, in one embodiment, the UE may be configured with NZP CSI-RS resources and/or SS/PBCH Block resources. Lor interference measurement, in one embodiment, the UE may be configured with NZP CSI-RS or CSI-IM resources. In one embodiment, for channel measurement, the UE may be configured with CSI-RS resource setting with up to 16 resource sets, with a total of up to 64 CSI-RS resources or up to 64 SS/PBCH Block resources.

[0065] For Ll-SINR reporting, in one embodiment, if the higher layer parameter nrofReportedRS in CSI-ReportConfig is configured to be one, the reported Ll-SINR value is defined by a 7-bit value in the range [-23, 40] dB with 0.5 dB step size, and if the higher layer parameter nrofReportedRS is configured to be larger than one, or if the higher layer parameter groupBasedBeamReporting is configured as 'enabled', the UE shall use differential Ll-SINR based reporting, where the largest measured value of Ll-SINR is quantized to a 7-bit value in the range [-23, 40] dB with 0.5 dB step size, and the differential Ll-SINR is quantized to a 4-bit value. The differential Ll-SINR is computed with 1 dB step size with a reference to the largest measured Ll- SINR value which is part of the same Ll-SINR reporting instance. When NZP CSI-RS is configured for channel measurement and/or interference measurement, in one embodiment, the reported Ll-SINR values should not be compensated by the power offset(s) given by higher layer parameter powerControlOffsetSS or powerControlOffset .

[0066] When one or two resource settings are configured for Ll-SINR measurement, in one embodiment, if the higher layer parameter timeRestrictionForChannelMeasurements in CSI- ReportConfig is set to ‘notConfigured’’ , the UE shall derive the channel measurements for computing Ll-SINR reported in uplink slot n based on only the SSB or NZP CSI-RS, no later than the CSI reference resource, (defined in TS 38.211) associated with the CSI resource setting.

[0067] If the higher layer parameter timeRestrictionForChannelMeasurements in CSI- ReportConfig is set to 'configured' . the UE shall derive the channel measurements for computing Ll-SINR reported in uplink slot n based on only the most recent, no later than the CSI reference resource, occasion of SSB or NZP CSI-RS (defined in TS 38.211) associated with the CSI resource setting.

[0068] If the higher layer parameter timeRestrictionForlnterferenceMeasurements in CSI- ReportConfig is set to "notConfigured’’ , the UE shall derive the interference measurements for computing Ll-SINR reported in uplink slot n based on only the CSI-IM or NZP CSI-RS for interference measurement (defined in TS 38.211) or NZP CSI-RS for channel and interference measurement no later than the CSI reference resource associated with the CSI resource setting.

[0069] If the higher layer parameter timeRestrictionForlnterferenceMeasurements in CSI- ReportConfig is set to "configured’’ , the UE shall derive the interference measurements for computing the Ll-SINR reported in uplink slot n based on the most recent, no later than the CSI reference resource, occasion of CSI-IM or NZP CSI-RS for interference measurement (defined in TS 38.211) or NZP CSI-RS for channel and interference measurement associated with the CSI resource setting.

[0070] In one embodiment, when the UE is configured with a CSI-ReportConfig with the higher layer parameter reportQuantity set to 'cri-SINR-Capability[Set]Index' or 'ssb-Index-SINR- Capability[Set]Index' an index of UE capability value, indicating the maximum supported number of SRS antenna ports, is reported along with the pair of SSBRI/CRI and Ll-SINR.

[0071] As described in more detail below, to assist a network entity in properly selecting its active antenna panel(s) or TRP(s) at a given time, a UE can report one or multiple candidate beams for each antenna panel or TRP, respectively, in a single CSI report.

[0072] In one embodiment, a UE receives a CSI report configuration that includes a plurality of channel measurement resource configurations (or a plurality of channel measurement resource groups/sets) and an indication to perform RSRP (or SINR) measurement and reporting (e.g., report quantity set to at least one resource index and at least one corresponding RSRP or SINR value) for each of the plurality of channel measurement resource configurations (or for each of the plurality of channel measurement resource groups/sets). The UE, in such an embodiment, performs measurements on resources configured by the plurality of channel measurement resource configurations (or the plurality of channel measurement resource groups/sets) and reports a configured or predefined number of resource indices and corresponding RSRP or SINR values for each channel measurement resource configuration (or for each channel measurement resource group/set).

[0073] In another embodiment, a UE receives a CSI report configuration that includes a plurality of channel measurement resource sets, each channel measurement resource set comprising one or more resource subsets, and an indication to perform RSRP (or SINR) measurement and reporting for each channel measurement resource set. The CSI report configuration, in one embodiment, further includes an indication to perform group-based beam reporting using one or more resource subsets of a given channel measurement resource set for some channel measurement resource sets (e.g. one CRI from resource subset 1 and another CRI from resource subset 2, which can be received by the UE simultaneously) and an indication to report a configured number of resource indicators (e.g., beams) of a given channel measurement resource set for other channel measurement resource sets. In one embodiment, the UE reports a configured number of groups of resource indicators and corresponding groups of RSRP/SINR values for some channel measurement resource sets configured with group-based beam reporting and reports a configured number of resource indicators and corresponding RSRP/SINR values for other channel measurement resource sets configured with non-group based beam reporting. [0074] In an implementation, a UE receives a first parameter (e.g., parameter nrofReportedRS) requesting a firstnumber of CRIs/SSBRIs and corresponding RSRP/SINR values to be reported for a first CSI resource configuration (or a first CSI resource set) and a second parameter (e.g., nrofReportedRS2) requesting a second number of CRIs/SSBRIs and corresponding RSRP/SINR values to be reported for a second CSI resource configuration (or a second CSI resource set). The UE, in one embodiment, measures CSI resources of the first and second CSI resource configurations (or CSI resource sets) and selects and reports the first number of CRIs/SSBRIs and corresponding RSRP/SINR values for the first CSI resource configuration and the second number of CRIs/SSBRIs and corresponding RSRP/SINR values for the second CSI resource configuration. If the second parameter is not configured, in one embodiment, the UE reports the first number of CRIs/SSBRIs and corresponding RSRP/SINR values for the second CSI resource configuration. Alternatively, in one embodiment, if the second parameter is not configured, the UE reports one CRI/SSBRI and a corresponding RSRP/SINR value for the second CSI resource configuration.

[0075] In another implementation, a UE receives a first parameter (e.g., parameter nrofReportedRSgroup) requesting a first number of groups of CRIs/SSBRIs and corresponding RSRP/SINR values to be reported for first and second CSI resource configurations (or first and second CSI resource sets) and a second parameter (e.g. nrofReportedRS ) requesting a second number of CRIs/SSBRIs and corresponding RSRP/SINR values to be reported for the second CSI resource configuration (or the second CSI resource set), where the first CSI resource configuration (or the first CSI resource set) corresponds to the CSI resource configuration/set associated with the largest measured value of Ll-RSRP or Ll-SINR. The UE, in one embodiment, measures CSI resources of the first and second CSI resource configurations (or CSI resource sets), determines the first CSI resource configuration/set, and reports the first number of groups of two CRIs/SSBRIs, for each group a first CRI/SSBRI from the first CSI resource configuration/set and a second CRI/SSBRI from the second CSI resource configuration/set, and corresponding first number of pairs of RSRP/SINR values, and the second number of CRIs and corresponding RSRP values for the second CSI resource configuration.

[0076] For example, if a UE is configured with a CSI-ReportConfig with the higher layer parameter reportQuantity set to 'cri-RSRP', 'ssb-Index-RSRP', 'cri-RSRP-Capability [Set] Index' or 'ssb-Index-RSRP-Capability[Set]Index', or if the UE is configured with a CSI-ReportConfig with the higher layer parameter reportQuantity set to 'cri-SINR', 'ssb-Index-SINR', 'cri-SINR- Capability[Set]Index' or 'ssb-Index-SINR-Capability[Set]Index', if the UE is configured with the higher layer parameter groupBasedBeamReporting-rl8 set to 'disabled', the UE is not required to update measurements for more than 64 CSI-RS and/or SSB resources, and the UE shall report in a single report nrofReportedRS (higher layer configured) different CRI(s) or SSBRI(s) for a first CSI resource set and nrofReportedRS2 (higher layer configured) different CRI(s) or SSBRI(s) for a second CSI resource set for each report setting; otherwise, if the UE is configured with the higher layer parameter groupBasedBeamReporting-r 18 set to ‘enabled’, the UE is not required to update measurements for more than 64 CSI-RS and/or SSB resources, and the UE shall report in a single reporting instance nrofReportedRSgroup, if configured, group(s) of two CRIs or SSBRIs selecting one CSI-RS or SSB from each of the two CSI resource sets for each report setting, where for each group, CRI or SSBRI of the CSI resource set associated with the largest measured value of Ll- RSRP is present first and CSI-RS and/or SSB resources of each group can be received simultaneously by the UE. Further, the UE shall report in the same reporting instance nrofReportedRS2 (higher layer configured) different CRI(s) or SSBRI(s) for another CSI resource set not associated with the largest measured value of Ll-RSRP for each report setting.

[0077] Figures 2A-2C illustrate an example of an enhanced CSI-ReportConfig information element (“IE”) for techniques for CSI measurement and reporting. In one embodiment, the IE CSI-ReportConfig is used to configure a periodic or semi-persistent report sent on physical uplink control channel (“PUCCH”) on the cell in which the CSI-ReportConfig is included, or to configure a semi-persistent or aperiodic report sent on physical uplink shared channel (“PUSCH”) triggered by downlink control information (“DCI”) received on the cell in which the CSI-ReportConfig is included (in this case, the cell on which the report is sent is determined by the received DCI).

[0078] In one embodiment, the carrier 202 indicates in which serving cell the CSI- ResourceConfig indicated below are to be found. If the field is absent, the resources are on the same serving cell as this report configuration.

[0079] In one embodiment, the resourcesForChannelMeasurement 204 and the resourcesForChannelMeasurement2List 206 indicate resources for channel measurement or a list of resource sets for channel measurement. csi-ResourceConfigld 208 of a CSI-ResourceConfig is included in the configuration of the serving cell indicated with the field “carrier” above.

[0080] In one embodiment, the csi-IM-ResourcesForlnterference 210 indicates CSI-IM resources for interference measurement. csi-ResourceConfigld 208 of a CSI-ResourceConfig is included in the configuration of the serving cell indicated with the field “carrier” above. The CSI- ResourceConfig indicated here, in one embodiment, contains only CSI-IM resources. In one embodiment, the bwp-Id in that CSI-ResourceConfig is the same value as the bwp-Id in the CSI- ResourceConfig indicated by resourcesForChannelMeasurement 204. [0081] In one embodiment, the nzp-CSI-RS-ResourcesForlnterference 212 indicates NZP- CSI-RS resources for interference measurement. csi-ResourceConfigld 208 of a CSI- ResourceConfig is included in the configuration of the serving cell indicated with the field “carrier” above. The CSI-ResourceConfig indicated here, in one embodiment, contains only NZP- CSI-RS resources. In one embodiment, the bwp-Id m that CSI-ResourceConfig is the same value as the bwp-Id in the CSI-ResourceConfig indicated by resourcesForChannelMeasurement.

[0082] In one embodiment, the nrofReportedRS 214, nrofReportedRS2 216 indicate the number (A) of measured RS resources to be reported in first and second channel measurement resource configurations in a non-group-based report. When the field is absent, in one embodiment, the UE applies the value 1.

[0083] In one embodiment, the nrofReportedRSgroup 218 indicates the number (N) of measured RS resource groups to be reported in a group-based report. When the field is absent the UE applies the value 1.

[0084] In some embodiments, the terms antenna, panel, and antenna panel are used interchangeably. An antenna panel may be a hardware that is used for transmitting and/or receiving radio signals at frequencies lower than 6GHz, e.g., frequency range 1 (“FR1”), or higher than 6GHz, e.g., frequency range 2 (“FR2”) or millimeter wave (“mmWave”). In some embodiments, an antenna panel may comprise an array of antenna elements, wherein each antenna element is connected to hardware such as a phase shifter that allows a control module to apply spatial parameters for transmission and/or reception of signals. The resulting radiation pattern may be called a beam, which may or may not be unimodal and may allow the device (e.g., UE, node) to amplify signals that are transmitted or received from one or multiple spatial directions.

[0085] In some embodiments, an antenna panel may or may not be virtualized as an antenna port in the specifications. An antenna panel may be connected to a baseband processing module through a radio frequency (“RF”) chain for each of transmission (egress) and reception (ingress) directions. A capability of a device in terms of the number of antenna panels, their duplexing capabilities, their beamforming capabilities, and so on, may or may not be transparent to other devices. In some embodiments, capability information may be communicated via signaling or, in some embodiments, capability information may be provided to devices without a need for signaling. In the case that such information is available to other devices such as a CU, it can be used for signaling or local decision making.

[0086] In some embodiments, an antenna panel may be a physical or logical antenna array comprising a set of antenna elements or antenna ports that share a common or a significant portion of an RF chain (e.g., in-phase/quadrature (“I/Q”) modulator, analog to digital (“A/D”) converter, local oscillator, phase shift network). The antenna panel may be a logical entity with physical antennas mapped to the logical entity. The mapping of physical antennas to the logical entity may be up to implementation. Communicating (receiving or transmitting) on at least a subset of antenna elements or antenna ports active for radiating energy (also referred to herein as active elements) of an antenna panel requires biasing or powering on of the RF chain which results in current drain or power consumption in the device (e.g., node) associated with the antenna panel (including power amplifier/low noise amplifier (“UNA”) power consumption associated with the antenna elements or antenna ports). The phrase "active for radiating energy," as used herein, is not meant to be limited to a transmit function but also encompasses a receive function. Accordingly, an antenna element that is active for radiating energy may be coupled to a transmitter to transmit radio frequency energy or to a receiver to receive radio frequency energy, either simultaneously or sequentially, or may be coupled to a transceiver in general, for performing its intended functionality. Communicating on the active elements of an antenna panel enables generation of radiation patterns or beams.

[0087] In some embodiments, depending on implementation, a “panel” can have at least one of the following functionalities as an operational role of Unit of antenna group to control its Tx beam independently, Unit of antenna group to control its transmission power independently, Unit of antenna group to control its transmission timing independently. The “panel” may be transparent to another node (e.g., next hop neighbor node). For certain condition(s), another node or network entity can assume the mapping between device's physical antennas to the logical entity “panel” may not be changed. For example, the condition may include until the next update or report from device or comprise a duration of time over which the network entity assumes there will be no change to the mapping. Device may report its capability with respect to the “panel” to the network entity. The device capability may include at least the number of “panels”. In one implementation, the device may support transmission from one beam within a panel; with multiple panels, more than one beam (one beam per panel) may be used for transmission. In another implementation, more than one beam per panel may be supported/used for transmission.

[0088] In some of the embodiments described, an antenna port is defined such that the channel over which a symbol on the antenna port is conveyed can be inferred from the channel over which another symbol on the same antenna port is conveyed.

[0089] Two antenna ports are said to be quasi co-located (“QCU”) if the large-scale properties of the channel over which a symbol on one antenna port is conveyed can be inferred from the channel over which a symbol on the other antenna port is conveyed. The large-scale properties include one or more of delay spread, Doppler spread, Doppler shift, average gain, average delay, and spatial Rx parameters. Two antenna ports may be quasi-located with respect to a subset of the large-scale properties and different subset of large-scale properties may be indicated by a QCL Type. The QCL Type can indicate which channel properties are the same between the two reference signals (e.g., on the two antenna ports). Thus, the reference signals can be linked to each other with respect to what the device can assume about their channel statistics or QCL properties. For example, qcl-Type may take one of the following values. Other qcl-Types may be defined based on combination of one or large-scale properties - 'QCL-TypeA': {Doppler shift, Doppler spread, average delay, delay spread}; 'QCL-TypeB': {Doppler shift, Doppler spread}; 'QCL-TypeC: {Doppler shift, average delay}; and 'QCL-TypeD': {Spatial Rx parameter} .

[0090] Spatial Rx parameters may include one or more of: angle of arrival (“AoA”) Dominant AoA, average AoA, angular spread, Power Angular Spectrum (“PAS”) of AoA, average AoD (angle of departure), PAS of AoD, transmit/receive channel correlation, transmit/receive beamforming, spatial channel correlation etc.

[0091] The QCL-TypeA, QCL-TypeB and QCL-TypeC may be applicable for all carrier frequencies, but the QCL-TypeD may be applicable only in higher carrier frequencies (e.g., mmWave, FR2 and beyond), where essentially the device may not be able to perform omnidirectional transmission, i.e. the device would need to form beams for directional transmission. A QCL-TypeD between two reference signals A and B, the reference signal A is considered to be spatially co-located with reference signal B and the device may assume that the reference signals A and B can be received with the same spatial filter (e.g., with the same RX beamforming weights).

[0092] An “antenna port” according to an embodiment may be a logical port that may correspond to a beam (resulting from beamforming) or may correspond to a physical antenna on a device. In some embodiments, a physical antenna may map directly to a single antenna port, in which an antenna port corresponds to an actual physical antenna. Alternately, a set or subset of physical antennas, or antenna set or antenna array or antenna sub-array, may be mapped to one or more antenna ports after applying complex weights, a cyclic delay, or both to the signal on each physical antenna. The physical antenna set may have antennas from a single module or panel or from multiple modules or panels. The weights may be fixed as in an antenna virtualization scheme, such as cyclic delay diversity (“CDD”). The procedure used to derive antenna ports from physical antennas may be specific to a device implementation and transparent to other devices.

[0093] In some of the embodiments described, a TCI-state (Transmission Configuration Indication) associated with a target transmission can indicate parameters for configuring a quasicollocation relationship between the target transmission (e.g., target RS of DM-RS ports of the target transmission during a transmission occasion) and a source reference signal(s) (e.g., SSB/CSI-RS/SRS) with respect to quasi co-location type parameter(s) indicated in the corresponding TCI state. The TCI describes which reference signals are used as QCL source, and what QCL properties can be derived from each reference signal. A device can receive a configuration of a plurality of transmission configuration indicator states for a serving cell for transmissions on the serving cell. In some of the embodiments described, a TCI state comprises at least one source RS to provide a reference (device assumption) for determining QCL and/or spatial filter.

[0094] In some of the embodiments described, a spatial relation information associated with a target transmission can indicate parameters for configuring a spatial setting between the target transmission and a reference RS (e.g., SSB/CSI-RS/SRS). For example, the device may transmit the target transmission with the same spatial domain filter used for reception the reference RS (e.g., DL RS such as SSB/CSI-RS). In another example, the device may transmit the target transmission with the same spatial domain transmission filter used for the transmission of the reference RS (e.g., UL RS such as SRS). A device can receive a configuration of a plurality of spatial relation information configurations for a serving cell for transmissions on the serving cell.
