Abstract: In some access networks, group-based beam reporting configured for a UE may be based on heuristics and/or based on UE implementation, and therefore, may lack adequate information regarding joint channel properties for simultaneous transmission and reception on a channel configured with a base station. Configurations of UEs and base stations are described herein that support various feedback metrics for resource grouping in association with transmission and reception operation modes and/or channel states, such as MIMO schemes, SINRs, channel properties, and the like. Base stations may dynamically indicate metrics to be reported by UEs so that simultaneous transmission and reception may be sufficiently supported.
