1. A method performed by a wireless transmit/receive unit (WTRU) comprising a plurality of antenna elements, the method comprising:
receiving, by the WTRU, configuration information indicating a plurality of beam processes, wherein at least one of the plurality of beam processes has a respective identifier, wherein the at least one of the plurality of beam processes is associated with an uplink reference signal, and wherein the at least one of the plurality of beam processes is provisioned with resources for the uplink reference signal, the provisioned resources including an indication of time and frequency resources,
wherein the uplink reference signal is associated with one or more antenna ports;
receiving, by the WTRU, downlink control information comprising an indication of the respective identifier of the at least one of the plurality of beam processes;
selecting, by the WTRU, a beam process from among the plurality of beam processes based on the indication of the respective identifier of the at least one of the plurality of beam processes received in the downlink control information; and
performing an uplink transmission, by the WTRU, based on the selected beam process.
