Abstract
A user equipment (UE) device may communicate with a wireless base station (BS). Each antenna in a phased antenna array on the UE may receive a reference signal transmitted by the BS during the beam training interval. Transceiver circuitry may measure wireless performance metric data from the reference signal. While receiving the reference signal, control circuitry may selectively activate different individual antennas, may selectively activate different subsets of antennas, or may concurrently activate all of the antennas in the array. The control circuitry may identify, based on the wireless performance metric data, a first set of the antennas in the array to that are being blocked by an external object and a second set of antennas array that are not blocked. After the beam training interval, the transceiver may use the second set of antennas to convey wireless data with the BS while the first set of antennas are disabled.
