A communication network comprises a plurality of bridging station BRS1-BRS6 deployed around a base station 130, so defining a circumference around it. Each bridging station BRS1-BRS6 comprises one or more directional antennas operable to generate a coverage area 101-106 lying predominantly outside the circumference. This forms an outer zone predominantly outside the circumference serviced by the bridging stations BRS1-BRS6 and an inner zone within the circumference serviced by the base station 130. In operation, the base station 130 applies an interference cancellation technique (943, fig.11) to separate out signal components originating from respective bridging station BRS1-BRS6 transmissions. The interference cancellation technique may comprise reconstructing the stronger signals from the bridging stations BRS1-BRS6 and subtracting the reconstructed signals from the received signal to leave only the remaining inner zone signals superposed upon each other. A multi-user detection (MUD) technique (944, fig.11) may then be applied to the remaining inner zone signals. |
