    摘要： A method and a target node for preventing collisions between networks communicating based on a carrier sense multiple access/collision avoidance (CSMA/CA) scheme, are provided. The method includes synchronizing an object network with a neighboring network. The method further includes allocating, to the object network, a slot index based on a number of the networks, and a contention window (CW) size. The method further includes setting, for the object network, a back-off counter value based on the CW size. The method further includes reducing the back-off counter value based on a channel state of the object network, and the slot index. The method further includes transmitting data related to the neighboring network based on the back-off counter value.

    摘要： A multi-cell communication system comprises at least a first base station and first terminal and a second base station and second terminal. When the first and second base stations need to perform interference control, the first terminal may relay a message related to the interference control between the first base station and the second base station. That is, the first terminal may transfer a message related to the interference control from the first base station to the second base station, and a message related to the interference control from the second base station to the first base station. As such, the first base station and the second base station can transmit/receive messages that are for performing interference control via the first terminal.
