1. A first wireless transmit/receive unit (WTRU) comprising:
a processor and a memory, wherein the processor and the memory are configured to:
send, to a second WTRU, an initial beam pair link establishment indicator, wherein the initial beam pair link establishment indicator comprises information indicating time domain and frequency domain resources to be used for initial beam sweeping;
transmit a first set of swept beams via the time domain and frequency domain resources indicated by the initial beam pair link establishment indicator, each beam of the first set of swept beams comprising a reference signal; and
receive, from the second WTRU, an indication of one or more preferred beams comprising one or more beams selected from the first set of swept beams.
