A method, scheduler, and processor program product for scheduling transmission of packets from a base station to a mobile station. A data rate control index is received from a mobile station. A transmission format is selected using the received data rate control index. The selected transmission format uses a payload size that is smaller than a largest compatible payload size for another transmission format corresponding to the received data rate control index and that is smaller than a total size of packets waiting to be transmitted.

Transmission format selection for optimizing transmission of delay sensitive traffic

The present invention supports a scheduling protocol on a wireless communication network to transmit data packets stored in a queue from a user. Two performance metrics are generated and summed to provide a priority. The performance metrics are based on the delay for the data packets stored in the queue and the rate that the data packets can be transmitted on the network. The user with the higher calculated priority for the current time slot has its data packets transmitted.

Optimized scheduling method for delay-sensitive traffic on high speed shared packet data channels

A method, apparatus, and computer-readable medium encoded with computer-executable instructions for transmitting delay sensitive packets. A data rate control index is received from a mobile station for use in transmitting the delay sensitive packets to the mobile station. A transmission format is selected using the received data rate control index to form a selected transmission format. The selected transmission format uses a payload size that is smaller than a largest compatible payload size for another transmission format corresponding to the data rate control index and is selected to reduce transmission time of the packets. The delay sensitive packets are transmitted to the mobile station using the selected transmission format.

A method, apparatus, and computer usable program code for creating a pseudo user from a plurality of users. Packets from the buffers are combined for the plurality of users into a buffer for the pseudo user. A multi-user packet is formed using packets from the pseudo user buffer, wherein the packets have older expiration times as compared to expiration times of other packets in the pseudo user buffer. The multi-user packet is transmitted to the mobile station.

Multi-user scheduling for optimizing transmission of delay sensitive traffic

A dynamic distribution of traffic load across multiple carriers in a wireless communication system. The wireless communication system includes a Base Transmittal Station (BTS) and one or more Access Terminals (ATs). An arriving traffic flow is placed on the carrier pair preferably having the most excess capacity. It is determined whether the new traffic flow is symmetric or asymmetric, and whether it is a best effort (BE) or a delay sensitive (DS) flow type. A procedure is then selected and used to calculate a loading metric for each carrier pair, the new traffic flow being assigned to the carrier pair having the lowest metric.
