  • Patent number: 11950263
    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: 20240097746
    Abstract: Apparatuses, systems, and methods for multi-TRP by a UE, including out of order delivery of PDSCH, PUSCH, and/or DL ACK/NACK. The UE may receive, from a base station, a configuration that may include multiple control resource set (CORESET) pools and each CORESET pool may be associated with an index value. The UE may determine that at least two DCIs of the multiple DCIs end at a common symbol and determine, based on one or more predetermined rules, when the UE may be scheduled to receive PDSCHs, transmit PUSCHs, and/or transmit ACK/NACKs from CORESETs associated with the at least two DCIs.

  • Patent number: 11895689
    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.

  • Publication number: 20240022309
    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 given SSB may be measured in place of the SSB.

  • Publication number: 20230300641
    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.

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: 20230156502
    Abstract: An approach is described for a user equipment (UE) to receive a channel state information (CSI) reporting configuration message from a source device of a first cell and receive a channel state information reference signal (CSI-RS) from a second cell via the source device. The UE determines a first number of CSI-RS resources of a first time slot duration corresponding to the first cell, a second number of CSI-RS resources of a second time slot duration corresponding to the second cell, an overall time slot duration based on the first and the second time slot duration, an overall number of CSI-RS resources of the overall time slot duration based at least on the first and the second number of CSI-RS resource, generates a capability report at least based on the overall number of CSI-RS resource, and transmits the capability report to the source device.
