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: Various communication systems may benefit from an improved resource block group allocation in a cell. A method may include determining at a network entity a common frequency resource allocation grid in a cell. The method may also include configuring at the network entity a frequency location of a bandwidth part of a user equipment within the cell. The frequency location of the bandwidth part may be offset from a reference point of the common frequency resource allocation grid. In addition, the method may include determining a size of one or more of a plurality of resource block groups within the bandwidth part of the user equipment based on the frequency location of the bandwidth part and the reference point. Further, the method may include transmit downlink control information from the network entity to the user equipment.
