  • Publication number: 20230042538
    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.

  • Patent number: 11570782
    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.

  • Publication number: 20230025057
    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.

  • Publication number: 20220311499
    Abstract: Systems and methods for control signaling for beam searching latency reduction are disclosed herein. A g Node B (gNB) may determine that a first Synchronization Signal Block (SSB) and a second SSB are to be spatially correlated and may select a first transmit (Tx) beam to transmit the first SSB and a second Tx beam to transmit the second SSB accordingly. The gNB may also transmit a correlation message including spatial correlation information to help a UE determine the spatial correlation. The UE may measure the first SSB on a first subset of a plurality of receive (Rx) beams and measure the second. SSB on a second subset of the plurality of Rx beams, and select an Rx beam for one or both. In some embodiments, channel state information reference signals (CSI-RS) that are quasi co-located (QCLed) with a Oven SSB may be measured in place of the SSB.

Each measurement resource may include multiple-port CSI-RS ports. The UE may indicate, to the base station, selection of a measurement resource when multiple measurement resources are configured, and may also report layer independent or layer common selection of a subset of CSI-RS ports included in the indicated single measurement resource or multiple measurement resources.

  • Publication number: 20220078801
    Abstract: An electronic device may receive, from a radio node, a measurement configuration associated with a wireless communication system. In response, the electronic device may perform measurements using narrow beam patterns based at least in part on a network configuration, where the narrow beam patterns are narrower than a wide beam pattern of the electronic device. Furthermore, performing the measurements using the narrow beams pattern may include performing a beam-pattern search up to the network configuration. Then, the electronic device may perform an SCell activation procedure of an SCell with the radio node. Note that the SCell activation procedure may include reporting, to the radio node, CSI of a narrow beam pattern of the SCell that is to be activated, where the narrow beam pattern is narrower than the wide beam pattern of the electronic device, and the narrow beam pattern is based at least in part on the measurements.
