Method and apparatus for reducing transmission errors in a third generation cellular system |
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. 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 NACK or 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. The Node B compares the contents of the first field to the contents of the second field. The Node B resends the transmission signal to the WTRU if the contents of the first and second fields are not logically consistent.
