ABSTRACT:
A method and apparatus for estimating and reporting the quality of a wireless communication channel between a wireless transmit/receive unit (WTRU) and a Node-B. A modulated signal is received from the Node-B over the communication channel and a channel estimation is performed on the modulated signal to provide a channel estimate. In one embodiment, the modulated signal is demodulated based on the channel estimate to provide a demodulated signal and a signal-to-interference (SIR) estimate based on the demodulated signal is obtained. The quality of the communication channel is estimated based on at least the SIR estimate. In an alternate embodiment, a SIR estimate based on the channel estimate is obtained. The quality of the communication channel is estimated based on the SIR estimate and additional information including at least one of delay spread, transmit power and WTRU velocity information.
