ABSTRACT:
A wireless communication method and system for detecting and correcting transmission errors. The system includes at least one wireless transmit/receive unit (WTRU) in communication with a Node B. The Node B sends a transmission signal (e.g., containing a protocol data unit (PDU)) to the WTRU. The WTRU generates a revert message having a first field and a second field to indicate whether the transmission signal was successfully received at the WTRU. The WTRU inserts a negative acknowledgement (NACK) message or positive acknowledgement (ACK) message into the first field and inserts a respective channel quality identifier (CQI) value corresponding to a worst or best possible value of CQI into the second field. The WTRU transmits the revert message to the Node B which compares the contents of the first and second fields. The Node B resends the transmission signal to the WTRU if the contents of the first and second fields are not logically consistent.
