Beam management procedure triggering and signaling delivery in fall-back mode

Abstract:

Network devices and systems in 5G and new radio (NR) infrastructures can utilize beam management operations to ensure communications for beam management procedure triggering including beam reporting, even during fall-back mode when the current receive (Rx) beam for downlink (DL) and transmit (Tx) beam for uplink (UL) fail. Additionally, reduction in overhead can be achieved with a reference beam pair link based beam reporting in a fall-back mode or not. This beam reporting can be a group based beam reporting and based on Reference Signal Received Powers (RSRPs) of beams and a differential RSRP corresponding thereto.
