摘要：
A wireless communication method system for detecting and correcting transmission errors. The system includes at least one Wireless Transmit/Receive Unit (WTRU) in communication with a Node B. At step 405 the Node B sends a transmission signal (including 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 transmits the Revert Message to the Node B. The Node B receives the first field (step 410) and the second field (step 420) and determines the contents (steps 415 and 425). The Node B compares the contents of the first field to the contents of the second field (step 430). The Node B resends the transmission signal to the WTRU if the contents of the first and second fields are not logically consistent (step 450).
