Beam switching robustness in unlicensed radio frequency spectrum band

Abstract:

Methods, systems, and devices for wireless communications are described. A base station may determine a degradation of a communication beam associated with a user equipment (UE). The base station may transmit a first signal identifying a beam switch occasion for the UE. The UE may receive a second signal identifying the beam switch occasion based on an outcome of the contention-based procedure. In some cases, the UE may transmit a third signal acknowledging the beam switch occasion during an acknowledgment opportunity based on the second signal, and may perform a beam switch during the beam switch occasion based on transmitting the third signal.
