Abstract:
1. A method of scheduling transmit rates and transmit powers of data users of a first type of channel on a forward-link of a wireless communication system, the wireless communication system including a plurality of base stations and a plurality of data users, each data user configured to communicate with any base station by sending frames to the base station and receiving frames from the base station, the method comprising the steps of: determining an available base station power level at the beginning of a frame; predicting transmit power levels at the beginning of the frame for each data user of a second type of channel, wherein all of the data users use the first type of channel and the second type of channel, and multiplying the predicted transmit power levels for the second type of channel by gain factors to obtain transmit power levels for the first type of channel; determining transmission rates for each data user that are sustainable with the predicted required transmit power level; generating a priority index for each data user; and controlling an order of transmission for the data users so that the data user having the highest priority index transmits first over the next frame.
