Scheduling packet data transmissions in a packet data network based on early decoded channel feedback reports

A method of scheduling wireless packet data traffic on a downlink packet data traffic channel shared by a plurality of mobile stations, comprising:

• establishing a channel quality information repetition rate L requiring a first mobile station reporting channel quality to the base station to repeat transmission of each channel quality information report to the base station at least L times;
• receiving a first channel quality information report from said 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;
• 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 decoding:
• wherein a first downlink transmission rate for transmissions to said first mobile station during said first channel quality interval is D12;
• wherein a second downlink rate for scheduling transmissions to said first mobile station during a second channel quality interval is D2, said second quality interval immediately succeeding said first channel quality interval;
• D2 being based on said first channel quality information report and different from D1;
• and
• further comprising transmitting, at transmission rate D1, 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.

A base station for a wireless communications system, said wireless communications system 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, the base station comprising:

• a transmitter operative to transmit downlink packet data to a plurality of mobile stations;
• a receiver operative to receive channel quality information reports from a first mobile station, including at least a first channel quality information report;
• one or more processing circuits operatively coupled to said transmitter and said receiver and configured to:
• successfully decode, after reception of said first channel quality information report one or more times, but prior to the Lth reception thereof, 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 wherein said receiver is operative to receive 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
• schedule packet data transmissions on a 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 D1;
• wherein a second downlink rate for scheduling transmissions to said first mobile station during a second channel quality interval is D2, said second quality interval immediately succeeding said first channel quality interval;
• D2 being based on said first channel quality information report and different from D1;
• and
• wherein said one or more processing circuits are configured to cause said transmitter to transmit, at transmission rate D1, one or more packets to said first mobile station during said first channel quality interval;
• said one or more packets scheduled by said one or more processing circuits based on said first decoded report.
