Method and apparatus for high rate packet data transmission

摘要

In a data communication system capable of variable rate transmission, high rate packet data transmission improves utilization of the forward link and decreases the transmission delay. Data transmission on the forward link is time multiplexed and the base station transmits at the highest data rate supported by the forward link at each time slot to one mobile station. The data rate is determined by the largest C/I measurement of the forward link signals as measured at the mobile station. Upon determination of a data packet received in error, the mobile station transmits a NACK message back to the base station. The NACK message results in retransmission of the data packet received in error. The data packets can be transmitted out of sequence by the use of sequence number to identify each data unit within the data packets.

1. A method for wireless communication, comprising:
measuring channel quality of a communication link in a wireless communication system, wherein the measuring channel quality comprises periodically measuring the channel quality of the communication link in each of a plurality of time periods; determining a quality indicator based on the measured channel quality; transmitting the quality indicator to a base station, wherein the transmitting the quality indicator comprises periodically transmitting the quality indicator in each of the plurality of time periods; and receiving from the base station a data packet having a variable packet size determined based on the quality indicator.
