摘要

Disclosed is a method and an apparatus for transmitting a frame in a wireless local area network. A method for transmitting a frame in a wireless local area network may comprise the steps of: an STA, operating on the basis of TPC, transmitting a TPC configuration request frame to an AP, the TPC configuration request frame containing information for a TPC STA communication resource requested by the STA; the STA receiving, from the AP, a TPC configuration response frame as a response to the TPC configuration request frame, the TPC configuration response frame containing information for allocating requested TPC STA communication resource; and the STA transmitting the frame to the AP by means of the requested TPC STA communication resource.

說明書

FIG. 2(B) illustrates a method of transmitting an RTS frame 233 and a CTS frame 235 to solve an exposed mode issue.

An STA C 250 may determine whether a collision occurs when a frame is transmitted to another STA D 260 on the basis of monitoring of the RTS frame 233 and CTS frame 235 of an STA A 230 and an STAB 240.

The STA B 240 may transmit the RTS frame 233 to the STA A 230, and the STA A 230 may transmit the CTS frame 235 to the STA B 240. The STA C 250 overhears only the RTS frame 233 transmitted by the STA B 240, and fails to overhear the CTS frame 235 transmitted by the STA A 230. Therefore, the STA C 250 may know that the STA A 230 is located out of a carrier sensing range of the STA C 250. Accordingly, the STA C 250 may transmit data to the STA D 260.

An RTS frame format and a CTS frame format are disclosed in the 8.3.1.2 RTS frame format and 8.3.1.3 CTS frame format of IEEE P802.11-REVmcTM/D2.0, October 2013.
