Methods and apparatus for communicating short messages from a first device, e.g., a femto cell device or peer to peer device, over communications resources which are being used by an OFDM macro network, e.g., cellular network, are described. The signal goes on top of, e.g., is transmitted on the same communications resource(s), on which a macro signal, e.g. a downlink signal from a cellular base station, is transmitted. Since the signals from the femto cell and/or peer to peer devices are transmitted on the same resources as the signals from the macro base station, they interfere with the macro signal and potentially destroy a portion of the macro signal. However, the signals transmitted by the femto cell devices and/or peer to peer devices are designed so that they cause little interference to the macro base station in terms of overall throughput and/or with the macro base station's ability to communicate control and/or pilot information.
A method of operating a first communications device located within a cell of a base station, to communicate information using communications resources which are also being used by said base station, the method comprising:
A first communications device comprising:
A computer program product for use in a first communications device, the computer program product comprising:
A first communications device comprising:
