Claim Text:
1. For use in a subscriber station in a wireless communication network, a method for transmitting feedback to a base station, the method comprising: receiving a signal comprising a first data stream and a second data stream from the base station, the first data stream formed using (1) first channel coding and modulation and (2) first error check coding with a first error check code and the second data stream formed using (1) second channel coding and modulation and (2) second error check coding with a second error check code different from the first error check code; attempting to decode the first and second data streams from the signal; determining whether the first data stream is successfully decoded using the first error check code and determining whether the second data stream is successfully decoded using the second error check code; and transmitting a single feedback message associated with both of the first and second data streams if the subscriber station is configured to transmit a single feedback message associated with both of the first and second data streams, wherein the single feedback message is an acknowledgement (ACK) if both of the first and second data streams are successfully decoded, and wherein the single feedback message is a negative acknowledgement (NACK) if at least one of the first and second data streams is unsuccessfully decoded.
