A system and method for performing multi-user random access procedures in a mobile telecommunications network between a base station and a user equipment (UE) having a plurality of antennas includes transmitting a random access signal set (RASS) message using one or more antennas of the plurality of UE antennas. In response to receiving the RASS message, the base station transmitting a random access response physical downlink control channel (RAR-PDCCH) message. In response to receiving the RAR-PDCCH message, transmitting a reciprocity reference signal set (RRSS) signal using the plurality of UE antennas.
