Preferably, step S118 (not shown) is also comprised according to the method for this preferred embodiment.

In step S118, when described first community is to when detecting that re-transmission reaches maximum times during other user device transmissions data described, the first base station sends to described 3rd base station the instruction reaching maximum retransmission.

Wherein, described maximum retransmission is used to indicate the maximum times allowing to carry out retransmitting of the first base station pre-configured (as agreement presets, or being that the first base station configures by described 3rd base station).Such as, maximum retransmission is 5 times.

Preferably, in response to from reach described in the first base station maximum times retransmit instruction, the first cell transmission from the 3rd base-station ceases to the first base station described in the 3rd data.

Continue to be described foregoing First example, community Cell_1 is when transmitting data to subscriber equipment Dev_2, detect that having carried out 5 secondary data retransmits, reach the maximum retransmission that macro base station eNB_1 is pre-configured, then macro base station eNB_1 sends the instruction reaching maximum retransmission to femto base station eNB_3.Then, in response to the instruction reaching maximum retransmission from macro base station eNB_1, femto base station eNB_3 stops transmitting data to community Cell_1.
