1. A method for a network node, comprising:
encoding a channel state information (CSI) reporting configuration communication for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) and a second TRP, the CSI reporting configuration communication including:
a first group of Channel Measurement Resource (CMR) resources for the first TRP; and
a second group of CMR resources for the second TRP, wherein the CSI reporting configuration communication comprises a single CMR set, and wherein the first group of CMR resources is a first subset within the single CMR set, and the second group of CMR resources is a second subset within the single CMR set;
decoding a CSI measurement communication received from the UE, the CSI measurement communication being based on the CSI reporting configuration communication, wherein the CSI measurement communication comprises a CSI-RS resource indicator (CRI), wherein
when the network node does not configure pairs of CMR resources, a bitwidth for the CRI for each pair of the pairs of CMR resources is ┌log 2 (N1×N2)┐, where N1 is a number of resources in the first group of CMR resources and N2 is a number of resources in the second group of CMR resources, and
when the network node does configure the pairs of CMR resources, the bitwidth for the CRI for each pair is ┌log 2 (M)┐, where M is a number of the pairs of CMR resources configured by the network node, wherein N1, N2, and M are positive integers; and
based on the CSI measurement communication, scheduling one or more downlink data transmissions.
