Abstract

Methods and apparatus used in a wireless communication system. A data request message may be periodically transmitting by a mobile station to a base station. The data request message may provide information about orthogonal codes to be used by the base station to communicate with the mobile station. The mobile station may receive data transmitted by the base station, the data being transmitted by the base station based on the information about the orthogonal codes provided in the data request message. The information about the orthogonal codes may be based on a quality measure made by the mobile station on a forward link pilot channel from the base station to the mobile station.
