Abstract:
1. A method for downlink transmission in a wireless communication system, the method comprising, at a base station: obtaining transmission status information, with respect to downlink transmissions, from a wireless subscriber unit, wherein the transmission status information indicates at least one of received signal power of a downlink beacon channel and error performance on the downlink transmissions; determining a block error rate of the downlink transmissions based on the transmission status information; selecting a transport format to be used in a downlink transmission based at least in part on the indicated received signal power of the downlink beacon channel and the block error rate; modifying a downlink transmit power level of the downlink transmission or adapting a transmission data rate, based at least in part on the selected transport format; and periodically obtaining updated transmission status information indicating at least one of received signal power of the downlink beacon channel and error performance on the downlink transmissions, wherein a period of obtaining the updated transmission status information is controlled by the base station.
