Abstract:
A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.

Claim (Index 29):
A receiver for Hybrid Automatic Repeat Request (HARQ) link layer protocol synchronization for an uplink transmission between a transmitter and the receiver in a wireless communication system, the receiver comprising processing circuitry configured to:\n receive a first protocol data unit in response to a transmitted explicit scheduling grant; evaluate the received first protocol data unit for errors; transmit a HARQ feedback message for the received first protocol data unit based on the error evaluation, wherein the HARQ feedback message is a positive acknowledgement for the received first protocol data unit; receive a subsequent second protocol data unit distinct from the first protocol data unit in response to a subsequent explicit scheduling grant transmitted in addition to the HARQ feedback message, wherein the subsequent explicit scheduling grant indicates to the transmitter to be authorized for transmitting the second protocol data unit; and receive the re-transmitted first protocol data unit in absence of transmission of a subsequent explicit scheduling grant.
