Abstract:
1. A method of transmitting a frame in a Wireless Local Area Network (WLAN) system, the method comprising: receiving, by a first station, information about an association identifier (AID) from an access point, the AID identifying the first station in the WLAN system; transmitting, by the first station, a Direct Link Setup (DLS) request frame to a second station to request a setup for a direct link with the second station, the DLS request frame including the AID of the first station; receiving, by the first station, a DLS response frame from the second station in response to the DLS request frame, the DLS response frame including an AID of the second station; generating, by the first station, a Physical Layer Convergence Procedure (PLCP) Protocol Data Unit (PPDU), the PPDU including a Very High Throughput-Signal (VHT-SIG) field and a PLCP Service Data Unit (PSDU); and transmitting, by the first station, the PPDU to the second station via the direct link, wherein the VHT-SIG field includes identity information indicating a partial AID that is formed from the AID of the second station and has a length shorter than the length of the AID of the second station.
