Abstract:
Various systems and methods disclosed herein describe improvements for beam management that leverage virtualization across a vertical polarization (V-Pol) and horizontal polarization (H-Pol). One or more of a user equipment (UE) and a base station may include an antenna array comprising V-Pol antenna elements and H-Pol antenna elements. The UE may determine a number of receive (Rx) beam of an Rx beam sweep are needed, signal this number to the base station, and perform the beam sweep according to one or both of the V-Pol and H-Pol. A UE may use group based beam reporting to indicate to the base station a transmit (Tx) beam upon which downlink MIMO using V-Pol and H-Pol may be supported by reporting a same transmission configuration indication (TCI) corresponding to the Tx beam for both a first Rx beam and a second Rx beam in a group based beam reporting message.
