Abstract
A millimeter-wave wireless multiple antenna system (200) is provided in which a UE (210) uses a multi-antenna subsystem (211) to sweep a plurality of receive beams (RX1-RXM) during each transmit beam in a plurality of transmit beams (TX1-TX64) used by the base station (201) to transmit an SSB, and then generates, for each receive beam, a received signal strength indicator (RSSI) value from samples of each transmitted SSB measured in said receive beam, thereby generating a plurality of RSSI values from which an optimal receive beam is selected based on a ranking of the RSSI values and then used to lock the UE (210) onto the optimal receive beam to perform a cell search which matches a transmit beam from the base station (201) to the optimal receive beam.
