<P>PROBLEM TO BE SOLVED: To reduce power consumption of a mobile station that uses receive diversity. <P>SOLUTION: For determining use of receive diversity in the mobile station, a control system 210 determines a demand level for use of communication resources. A transmitter communicates a message indicating use of receive diversity at a mobile station based on the determined demand level. 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 controls receive diversity by selecting a number of receiver chains 290 based on the determined transmit power level. In another aspect, the receiver 200 receives a channel and determines a channel condition of the channel and duration of the channel condition. The control system 210 controls receive diversity by selecting a number of receiver chains 290 based on the determined channel condition and the duration. <P>COPYRIGHT: (C)2010,JPO&INPIT |
