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.

Abstract: An electronic device may include communications circuitry, sensing circuitry, and a set of antennas having first and second feeds for covering different polarizations. The communications circuitry may transmit signals with a first polarization using each of the antennas and may concurrently transmit signals with a second polarization using all but a selected one of the antennas. The sensing circuitry may concurrently transmit sensing signals with the first polarization using one of the antennas and may receive sensing signals with the second polarization using the selected antenna. The sensing signals may include chirp signals generated to include muted periods that correspond to a range of frequencies that overlap frequencies at which the wireless circuitry is subject to radio-frequency interference. This may allow for concurrent wireless communications and sensing operations without interference between the communications circuitry and the sensing circuitry.
