Method and apparatus for high rate packet data transmission
First Claim
1. An apparatus for a communication system, comprising:
- means for receiving a data request message from a mobile station;
means for forwarding data addressed to the mobile station to a plurality of base stations, whereby the data is suitable for being transmitted from any one of the plurality of base stations to the mobile station; and
means for transmitting the data from at least one of the plurality of base stations based on a quality indicator received from the mobile station.

Abstract
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.
