For determining use of receive diversity in a mobile station, a control system ( 210 or 401 ) determines a demand level for use of communication resources. A transmitter ( 300 ) communicates a message indicating use of receive diversity at a mobile station based on the determined demand level. In another aspect, a receiver ( 200 ) receives a channel and determines transmit power level of the channel for being at a lower or upper transmit power level limit. The control system ( 210 or 401 ) controls receive diversity by selecting a number of receiver chains ( 290 ) based on the determined transmit power level. In another aspect, receiver ( 200 ) receives a channel and determines a channel condition of the channel and duration of the channel condition. Control system ( 210 or 401 ) controls receive diversity by selecting a number of receiver chains ( 290 ) based on the determined channel condition and the duration. |
