Patent ID: 8452232

Claim:
A method, comprising: determining at a MIMO repeater if there is a mobile station in the coverage area of the MIMO repeater, the MIMO repeater comprising one or more antenna paths comprising one or more receivers coupled to one or more respective receive antennas and one or more transmitters coupled to one or more respective transmit antennas; turning off one or more transmitters of the MIMO repeater if there is no mobile station in the coverage area of the MIMO repeater; if there is a mobile station in the coverage of the MIMO repeater: measuring a channel quality in one or more antenna paths of the MIMO repeater received from the mobile station in the coverage area; turning off transmitters of the MIMO repeater that do not have a sufficient channel quality in a respective antenna path; and transmitting uplink signals from the mobile station via transmitters of the MIMO repeater that have a sufficient channel quality in the respective antenna path; and turning off one or more transmitters of the MIMO repeater if an output power the one or more transmitters detected by a power detector circuit and a power comparison circuit exceeds a first threshold value.
