Abstract
A millimeter-wave wireless multiple antenna system () and method () are provided in which a UE () uses a multi-antenna subsystem () to identify a plurality of m strongest transmit beams () from the base station () based on power measurements of a plurality of synchronization signal blocks (SSBs) transmitted on a corresponding plurality of transmit beams by the base station (), and to generate a composite uplink random access channel (RACH) preamble () that is sent () to the base station () to identify the plurality of m strongest transmit beams and relative weights for each of the plurality of m strongest transmit beams which are used by the base station () to generate an optimal downlink transmit beam for use in sending a RACH response to the UE ().
