Abstract
An electronic device and methods for performing beam management (BM) in systems with antenna arrays capable of operating in combined radar and communication modes are disclosed herein. The electronic device comprises a processor and a plurality of antenna elements configured to operate in a first mode, in which the antenna elements are used for communications with beamforming, and a second mode, in which at least two of the antenna elements are used for radar and the remainder are used for the communications. The processor is configured to perform a mode switch on the antenna elements to switch between the first mode and the second mode, determine, after the mode switch, a new beam to use during a first BM cycle, perform, using the new beam, the first BM cycle to obtain signal quality measurements, and perform a second BM cycle using an updated beam based on the signal quality measurements.
