Abstract: Techniques of performing CSI reporting include identifying a cluster of TRPs sharing common information in their CSI and transmitting a complete CSI report to a selected TRP of the cluster while transmitting partial CSIs reports to other TRPs of the cluster. Along these lines, in an example implementation, a UE receives a CSI-RS from a network, with the CSI-RS carrying a plurality of reference symbols from a plurality of TRPs. Based on the plurality of symbols, the UE generates TRP data representing CSI feedback for each of the TRPs. From the CSI feedback, the UE identifies, as a cluster, a subset of the TRPs that share common information within the CSI feedback. The UE then sends first identification data identifying the subset of the TRPs that make up the cluster to the network.

Abstract: Systems, methods, apparatuses, and computer program products for radio link capability exposure for ultra-reliable low-latency communications (URLLC) and time sensitive communications (TSC). A method may include receiving, from a core network element, configuration of a reliability threshold for sending a failure report and/or a radio link capability report. The method may also include, when the reliability threshold is reached, sending a failure report to the core network element indicating that a required reliability cannot be fulfilled. The method may further include receiving instructions, from the core network element, to perform an action to address the unfulfilled reliability.
