1. A wireless transmit/receive unit (WTRU) comprising:
an antenna;
a transceiver, operatively coupled to the antenna; and
a processor, operatively coupled to the transceiver;
the antenna, the transceiver, and the processor configured to receive a configuration message including timing information for monitoring one or more subsets of a plurality of beams to receive a set of synchronization signals;
the antenna and the transceiver configured to receive the set of synchronization signals based on the timing information, wherein the received set of synchronization signals includes a primary synchronization signal and a secondary synchronization signal;
the antenna, the transceiver, and the processor configured to receive a reference signal along with a physical broadcast channel (PBCH) transmission, wherein the reference signal comprises a sequence that is derived from an index associated with one subset of the one or more subsets of the plurality of beams and associated with the received set of synchronization signals; and
the antenna and the transceiver configured to transmit a random access channel (RACH) transmission, wherein the RACH transmission includes a preamble sequence corresponding to the one subset of the one or more subsets of the plurality of beams.
