Abstract
Methods and apparatus for communicating precoding or beamforming information to users are disclosed. A feedback signal including a reported preceding matrix index (PMI) is received and a determination made as to the state of the feedback. Precoding rules associated with the determined state are then used to select a precoding matrix. The state information is transmitted to a wireless transmit receive unit (WTRU), which uses the state information and the precoding rules associated therewith to select the precoding matrix used to precoded a received precoded data signal.
