Abstract
A method performed by a WTRU may comprise receiving a beamformed physical control channel using a first beamformed pilot signal. The beamformed physical control channel may include an indication of a beam for a physical shared channel. The indicated beam of the physical shared channel and a beam of the beamformed physical control channel may be different. The method may further comprise receiving, based on the indicated beam, the physical shared channel using a second beamformed pilot signal. In an embodiment, the WTRU may receive an RRC message including an indication of a code of the first beamformed pilot signal.

19. The WTRU of claim 11, further comprising:
the receiver configured to receive a third beamformed pilot signal, wherein the physical shared channel is derived from the third beamformed pilot signal.
20. A wireless transmit/receive unit (WTRU) comprising:
a receiver configured to receive a beamformed physical control channel using a first beamformed pilot signal; the receiver configured to receive an indication of a beam for a physical shared channel on the beamformed physical control channel, wherein the indicated beam of the physical shared channel and a beam of the beamformed physical control channel are different; and the receiver configured to receive, based on the indicated beam, the physical shared channel using a second beamformed pilot signal.
