Method and apparatus for transmitting frame in WLAN system

摘要

A method of transmitting a frame in a Wireless Local Area Network (WLAN) system is provided. The method includes 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; and transmitting, by the first station, a Physical Layer Convergence Procedure (PLCP) Protocol Data Unit (PPDU) to the second station or the access point.

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; and transmitting, by the first station, a Physical Layer Convergence Procedure (PLCP) Protocol Data Unit (PPDU) to the second station or the access point, the PPDU including a Very High Throughput-Signal (VHT-SIG) field and a PLCP Service Data Unit (PSDU), wherein the VHT-SIG field includes identity information, wherein the identity information indicates a partial AID that is formed from the AID of the second station when the PPDU is destined to the second station, and wherein the identity information indicates a part of a basic service set identifier (BSSID) of the access point when the PPDU is destined to the access point.
