Abstract
A wireless network includes a relay station (RS) for extending wireless coverage of a base station. Data is sent by the base station and relayed through the RS to a mobile station (MS), where the data is associated with a preamble that is sent directly from the base station to the MS. A transmit power of the RS is adjusted for transmitting the data from the RS to the MS to reduce a difference between a first power level of the preamble received at the MS and a second power level of the data received at the MS. The uplink transmit power of the MS for the data sent to the RS is adjusted to compensate for the difference in path loss from MS to base station and MS to RS and to compensate for the difference in noise_plus_interference level at RS compared to that of the base station.
