Abstract
Systems and methods for communicating control data for multiple data channels using a single control channel. In one embodiment, a method is implemented in a WCDMA communications system. This method includes combining data rate information for a first data channel and data rate information for a second data channel in a mobile station, encoding the combined data rate information and transmitting the encoded combined data rate information from the mobile station to a base station via a single control channel. This method further includes receiving the encoded combined data rate information in the base station, decoding the encoded combined data rate information to produce the combined data rate information, and extracting the data rate information for the first and second data channels and decoding the first and second data channels using this information.
