1. An apparatus comprising:
at least one processor; and
at least one memory, where the at least one memory is storing instructions that when executed by the at least one processor, cause the apparatus to at least:
receive from a network node information for measurement reporting by the apparatus for beam management in a communication network,
wherein the information comprises at least one beam reporting configuration for more than one beam of at least two transmission reception points to be measured by the apparatus,
based on the at least one beam reporting configuration, determine beam reporting at least one pair of beams of the more than one beam of the at least two transmission reception points,
wherein the apparatus receives the more than one beam simultaneously and separately from each of the at least two transmission reception points in at least one of a synchronization signal block group or a transmission configuration indication group identifying each beam of the more than one beam,
wherein each beam of the more than one beam is identified by a reference signal associated with one of a channel state information reference signal or a synchronization signal block; and
select, based at least on the reference signal, a best two beams of the more than one beam from different groups of the at least one of a synchronization signal block group or a transmission configuration indication group or from two or more transmission reception points.
