Abstract
A method implemented by an apparatus having multiple antennas includes determining information that is associated with a baseband channel. The information indicating any of: measurement information and channel information. The apparatus transmits a signal for requesting baseband beam tracking. The signal transmission is 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.
Claims18
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.
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 detailed baseband channel information was not part of a multiple-in multiple-out (MIMO) setup procedure.
A wireless transmit/receive unit (WTRU) comprising a processor, a transmitter, and a receiver, wherein the processor, the transmitter, and the receiver are configured to:
- determine information that is associated with a baseband channel, the information indicating any of:
- measurement information and channel information;
- and
- transmit 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.
