Beam selection systems and methods

Abstract:

During a first P3 sweep that is associated with a first TCI state and during a second P3 sweep that is associated with a second TCI state, the UE stores the RSRP for each UE RX beam for each UE panel. Then, when the UE is scheduled for a downlink transmission through a DCI pointing to two these two TCI states, instead of only selecting the UE RX beam for respective panel based on the highest RSRP, the UE also takes the hypothetical inter-stream interference in to account when selecting the UE RX beams.
