Patent ID: 7680125

Claim:
A method of scheduling wireless packet data traffic on a downlink packet data traffic channel shared by a plurality of mobile stations, comprising: requiring mobile stations reporting channel quality to the base station for a given time interval to repeat transmission of the corresponding channel quality information report at least L times; receiving, at the base station, a first channel quality information report from a first mobile station one or more times, but less than L times; and, prior to reception of the Lth repetition of said first channel quality information report, said base station successfully decoding said first channel quality information report to form a first decoded report; wherein successive channel quality intervals are defined between the reception of Lth repetitions of successive channel quality information reports from said first mobile station, and further comprising receiving channel quality information reports from said first mobile station in a plurality of channel quality intervals, including a first channel quality interval ending with said Lth repetition of said first channel quality information report; and scheduling packet data transmissions on said downlink packet data traffic channel based on said first decoded report: wherein a first downlink transmission rate for transmissions to said first mobile station during said first channel quality interval is D 1 ; wherein a second downlink rate for scheduling transmissions to said first mobile station during second channel quality interval is D 2 , said second quality interval immediately succeeding said first channel quality interval; D 2 being based on said first channel quality information report and different from D 1 ; and further comprising transmitting, at transmission rate D 1 , one or more packets to said first mobile station during said first channel quality interval, said one or more packets scheduled based on said first decoded report.
