Method and apparatus for high rate packet data transmission
First Claim
1. An apparatus for a communication system, comprising:
- means for receiving a plurality of future transmission activity messages, each message corresponding to at least one transmitter and comprising information on future transmission activity or interference for the at least one transmitter at a future time after transmission of the message;
means for obtaining the information from each of the received messages;
means for determining a quality of a link in the communication system, based in part on the information on future transmission activity or interference obtained from the received messages; and
means for transmitting a quality indicator indicative of the quality of the link.

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.
