Method and apparatus for high rate packet data transmission
First Claim
1. An apparatus for a communication system, comprising:
- means for receiving, periodically, quality indicators from a plurality of mobile stations, each quality indicator indicative of a quality of a link in the communication system;
means for selecting mobile stations for data transmissions based on the received quality indicators;
means for allocating available resources to the selected mobile stations for the data transmissions and allocating no resources to unselected mobile stations; and
means for scheduling the data transmissions for the selected mobile stations as a function of the received quality indicators.

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.
