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.

Abstract: An apparatus configured to be employed in a gNodeB associated with a new radio (NR) communication system is disclosed. The apparatus comprises one or more processors configured to configure partial spatial reference information associated with at least one sounding reference signal (SRS) resource set of one or more SRS resource sets associated with a user equipment (UE), that forms a select SRS resource set. In some embodiments, the partial spatial reference information comprises information on a partial spatial reference resource configured for one or more SRS resources associated with the select SRS resource set, to be utilized by the UE to generate one or more SRS transmit beam patterns for transmitting the one or more SRS resources, respectively, such that the one or more SRS transmit beam patterns are in a spatial neighborhood of a beam pattern associated with the configured partial spatial reference resource.

Abstract: Enhanced channel state information (CSI) reporting may include encoding a CSI reporting configuration associated with a first transmission and reception point (TRP) and a second TRP. The CSI reporting configuration may include at least one codebook configuration. The at least one codebook may include at least one of a rank restriction configuration or a codebook subset restriction (CBSR) configuration. The at least one of the rank restriction configuration or the CBSR configuration may correspond to at least one of a particular type of TRP measurement, a particular TRP of the first TRP or the second TRP, or channel measurement resources (CMRs) associated with at least one of the first TRP or the second TRP. A CSI measurement communication received from a user equipment (UE) may be decoded. The CSI measurement communication may be based on the decoded CSI reporting configuration.

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.

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.

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: A method for operating user equipment (UE) includes generating, by the UE, a transmit precoding matrix indicator (TPMI) list including one or more TPMIs selected from a set of available TPMIs stored at a base station (BS). Data indicative of the TPMI list is transmitted to the BS. An index of the TPMI list is transmitted to the BS. Downlink control information (DCI) is received from the BS including an indication of at least one TPMI from the TPMI list based on the index. Uplink data is transmitted to the BS on a physical uplink shared channel (PUSCH) using the at least one TPMI.
