Abstract: The present invention provides definition of an identifier which is required for recognizing information essential for device to device communication, a transmission method thereof, and devices that support the same. The method for supporting device to device (D2D) communication in a wireless access system that supports D2D communication as one embodiment of the present invention comprises the steps of allowing a first D2D device to receive, from a base station, a broadcast message which contains a common D2D identifier (C-D2D-RNTI) for all D2D devices that perform D2D communication; and allowing the first D2D device to receive the transmitted D2D-related information by using the C-D2D-RNTI. In this situation, the wireless access system can support both D2D communication and cellular communication for a normal terminal instead of the D2D device.

Abstract: In the wireless LAN system, the station STA receives a frame and updates a corresponding Inter-BSS Network Allocation Vector (NAV) or Intra-BSS NAV according to whether the frame is an Inter-BSS (Basic Service Set) frame or an Intra-BSS frame. If the received frame cannot be distinguished from the Inter-BSS frame or the Intra-BSS frame, it updates the Inter-NAV, and after receiving the frame that cannot be distinguished from the Inter-BSS frame or the Intra-BSS frame, it receives the CF-End frame, and then the corresponding NAV is reset.
