Abstract

The amount of interference to communications in Time Division Duplexing (TDD) mode between a TDD mobile 14 and a TDD base station 8 from a mobile 10 operating in Frequency Division Duplexing (FDD) mode that is located near to the TDD base station can be reduced by providing a simulated FDD base station 19 located close to the TDD base station. The simulated FDD base station can be a simple FDD antenna coupled to a remote FDD base station 6, thereby causing the FDD mobile to be controlled to reduce its transmitting power as though it was close to an FDD base station. Alternatively, the FDD antenna, 18 can be connected to the Radio Network Controller 2 and simulate some, but not all , the functions of an FDD base station, so that the FDD mobile is handed over to the simulated base station and, once again is controlled to reduce its transmitting power. Alternatively, when the FDD antenna detects that an FDD mobile is transmitting at high power, the FDD mobile can be controlled to be handed over to another FDD frequency either at the same or a different FDD base station.
