Claim:
A method of operating a terminal in a wireless communications system, the system having a plurality of uplink and downlink channels available for use, the terminal being arranged to use an uplink channel and a downlink channel selected from the plurality, with the uplink channel lying adjacent, in frequency, to an uplink channel used by another terminal and the downlink channel not lying adjacent, in frequency, to a downlink channel used by the other terminal, the method comprising: transmitting a signal on the uplink channel used by the terminal, said uplink channel being an uplink channel to which a base station in communication with the other terminal does not have access; determining whether the terminal is transmitting at a power which may cause interference to the adjacent uplink channel; determining which downlink channel is paired with the adjacent uplink channel; monitoring that the determined down link channel and deciding, on the basis of the monitoring, whether there is a need to operate the terminal in a manner which will reduce interference.
