METHOD AND APPARATUS FOR CLOSED LOOP TRANSMIT DIVERSITY TRANSMISSION INITIAL ACCESS |
摘要 |
Uplink precoding in closed loop transmit diversity (CLTD). The methods and apparatus relate to precoder operations during an initial stage using default precoder tap weights, and a second stage wherein precoder weights obtained from a precoder control indicator channel information are used, provided the signal quality of the precoder control indicator channel is sufficiently reliable. The methods and apparatus also relate to procedures for responding to detection of an unreliable pre-coding control information (PCI) carried in a downlink feedback signal.
