Hi Baharath,

Beam management types p1,p2,p3 are specifically used in DL Beam management. Refer below types.

P1 Beam Selection gNB sweeps beam and UE select a best one and report it to gNB
P2 Beam Refinment for transmitter(gNB Tx) gNB refine beam(e.g, sweeping narrower beam over narrower range) and UE detects the best one and report it to gNB
P3 Beam Refinement for reciever(UE Rx) gNB fixes a beam(transmit the same beam repeatedly) and UE refines its reciever beam. It sets the Spatial Filter on reciever antenna array. This is used only when UE support beamforming
