Abstract: A user equipment (UE) transmits concurrent channel state information (CSI) processing capability information to a base station. The capability information can take various forms, and is intended to constrain the base station in the types of CSI requests that can be made to the UE. For example, the UE may indicate different CSI processing capabilities for intra-CC and inter-CC cases and/or for different codebook types. The UE may also specify supported combinations of codebook types for concurrent CSI reporting. The UE may also specify maximum resources or weighting factors for different codebook types. The UE may further restrict the rank information it provides and use a priority rule for "dropping" CSI report data due to payload size restrictions. The base station may direct, or the UE may implement, improved utilization of CSI resources that are shared for multiple concurrent CSI reports. Minimum time requirements for CSI reporting may also be relaxed.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing channel state information (CSI) reporting that includes a stale CSI report. Based at least in part on a CSI reporting configuration, a user equipment (UE) performs CSI measurements during a current reference time period, and generates one or more CSI reports including at least a stale CSI report. A stale CSI report is generated based at least in part on CSI measurements performed prior to the current reference time period. The UE further generates an uplink message including the one or more CSI reports, and transmits the uplink message to the base station under a reporting setting determined by the CSI reporting configuration.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing capability signaling design for 3rd Generation Partnership Project (3GPP) release 15 (Rel-15) and/or release 16 (Rel-16) multi-input multi-output (MIMO) enhancement. For example, systems and methods are provided implementing designs for New Radio (NR) MIMO channel state information (CSI) for a small bandwidth part (BWP) and/or a small number of subbands. For example, some aspects relate to a user equipment (UE) including a transceiver configured to communicate with a base station and a processor communicatively coupled to the transceiver. The processor receives, from the base station, a CSI reporting configuration message. The processor determines, using the CSI reporting configuration message, that a number of physical resource blocks (PRBs) of a BWP associated with the CSI reporting configuration message is less than a threshold number. The processor also generates and transmits a CSI report for the BWP.

Abstract: Apparatuses, systems, and methods for counting active resources for UE processing complexity related capability. A cellular base station may comprise at least one antenna; at least one radio coupled to the at least one antenna; and a processor coupled to the at least one radio. The cellular base station is configured to count a total number of active resources in a slot, wherein an active resource is defined for counting a number of CSI resources a UE needs to process simultaneously in a slot.

Abstract: A user equipment (UE) reports beam management information to a network. The UE receives a first group of multiple reference signals from a first transmission reception point (TRP) of a network, receives a second group of multiple reference signals from a second different TRP of the network, selects a first beam associated with one of the multiple reference signals of the first group, selects a second beam associated with one of the multiple reference signals of the second group and transmits a message to the network, the message including an indication of the selected first beam and second beam.

Abstract: Some embodiments include an apparatus, method, and computer program product for using group based reporting for beam management in a 5G wireless communications system. A user equipment (UE) can determine based on a signal-to-interference-plus noise ratio (SINR) or reference signal received power (RSRP) measurement, a ranking of two or more beam combinations, and transmit the ranking to a 5G node B (gNB). The UE can receive from the gNB, a transmission configuration indicator (TCI) codepoint that identifies a combination of two or more beams, where the TCI codepoint is based at least on the ranking. The UE can receive simultaneous transmissions via the combination, and transmit a report to the gNB that identifies by the TCI codepoint, SINRs that corresponds to the combination. In some embodiments the UE can simultaneously transmit on a second combination identified by a sounding reference signal (SRS) resource indicator (SRI) codepoint.
