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 base station and wireless communication (UE) may perform type II CSI-RS port selection based at least on partial reciprocity between an uplink path and a downlink path between the base station and the UE. The base station may identify dominant signal paths between the base station and the UE, based on measurements performed during uplink transmissions, and may transmit, to the UE, corresponding information indicative of CSI measurement and reporting configuration that may include a single measurement resource or multiple measurement resources. 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. Further enhancements include frequency domain compression enhancement and dynamic codebook parameter reconfiguration.

Abstract: Systems and methods are provided for to support user equipment (UE) channel state information (CSI) report of time domain channel properties. Embodiments herein consider Uplink Control Information (UCI) multiplexing, UCI omission, Interference Measurement Resource (IMR) configuration, and phase continuity handling. A channel state information report configuration (CSI-ReportConfig) may comprise details regarding measurement and reporting of time domain channel properties (TDCP) based on channel state information reference signal (CSI-RS) for tracking reference signal (TRS).

Abstract: Systems and methods are provided for to support user equipment (UE) channel state information (CSI) report of time domain channel properties. Embodiments of a UE herein may receive, from a network node, a CSI report configuration (CSI-ReportConfig). The CSI-ReportConfig may comprise details regarding measurement and reporting of time domain channel properties (TDCP) based on a CSI reference signal (CSI-RS) for tracking reference signal (TRS). The UE may determine invalid CSI-RS resources and valid CSI-RS resources based on a timing of a duplex direction change. The UE may measure and report TDCP based on the valid CSI-RS resources.
