PROBLEM TO BE SOLVED: To provide a method for suppressing interference between cells achievable with a simple structure and control algorithm, and a distributed radio communication base station system achievable of suppressing interference between cells with a simple structure and control algorithm.SOLUTION: Interference between cells can be suppressed by using a TDM function of a PON system. Specifically, by the TDM function, data destined to each ONU is delivered on a unit time basis and the ONU receives or discards data destined the self-ONU. Therefore, at a time the ONU receives the data destined to the self-ONU, there is no data in another ONU. Thus, only a base station connected to the ONU having received the data radio outputs, whereas the other base station does not radio output, so that interference between cells can be suppressed. |
