Abstract: A method is provided for supporting state mode transition by an entity of a cellular network in case that a plurality of networks interwork. When a value of interference caused by a neighbor entity of a wireless local area network (WLAN) is equal to or larger than a predefined threshold value, a first message instructing another entity of the WLAN to perform a mode transition from an active mode to an idle mode is transmitted to another entity of the WLAN. In response, a second message including information indicating whether status of the mode transition of the another entity of the WLAN is successful is received from the another entity of the WLAN. When the information indicates that the status of the mode transition of the another entity of the WLAN is successful, status information of the another entity of the WLAN is updated based on the second message.

Abstract: An embodiment of the present invention relates to a method in which a base station transmits a signal in a wireless communication system, comprising: a step of generating a reception acknowledgement response to the uplink data received from a terminal; and a step of mapping the reception acknowledgement response to a downlink time-frequency resource and transmitting the mapped result. The downlink time-frequency resource is located on a resource region excluding the control region indicated by a physical control format indicator channel, and associated with the index of the resource block with which the uplink data is transmitted.
