<p>A cellular radio telecommunications system is described which includes a base transceiver station for radio communication with a mobile terminal over an air interface. The base station includes at least a first and a second antenna device, the first and second antenna devices being adapted for providing radio coverage over a first and a second sector of a cell, respectively, the first and second sectors being substantially independent geographical areas and the combined geographical area of the sectors covering an angle of substantially 360° in the azimuth plane of the first and second antenna devices. A transmitter unit is provided comprising a first power amplifier, the transmitter unit transmitting substantially the same signal to the first and second antenna devices to provide omni-transmission to the cell. A first receiver unit receives signals from the first and second antenna devices and independently amplifies the received signals. A combiner selectively combines signals from the first receiver unit on a mobile terminal-by-mobile terminal basis. The system preferably supports soft handover.</p> |
