1. A method implemented by a wireless transmit/receive unit (WTRU) having multiple antennas, the method comprising:
determining information that is associated with a baseband channel, the information indicating any of: measurement information and channel information; and
transmitting a signal for requesting baseband beam tracking, the signal transmission based on a determination that system performance is degraded in a beamforming transmission and re-estimation of the baseband channel is part of a current link adaptation procedure.
