Methods and apparatus for channel quality indicator determination

A channel quality indicator value is determined on a per transport block basis. A signal-to-interference ratio estimate of a control channel and a channel quality estimate of user-data channel are employed in the determination of the channel quality indicator. The channel quality estimate of the user-data channel can include information about Automatic Retransmission Request (ARQ) processing, and the number of iterations of a Turbo decoder. Additionally, information about the Cyclic Redundancy Check (CRC), which is determined on a per transport block basis, can be employed in the channel quality indicator determination. The determined channel quality indicator is reported to the radio communication system.
