Abstract

Disclosed are a method and an apparatus for reporting information about a transmission failure frame. The method for reporting information about a transmission failure frame in a wireless LAN may comprise the steps of: creating, by an STA, the retransmission frame includes information about the transmission failure frame, the information about the transmission failure frame includes timestamp information and duration information, the timestamp information includes information about the transmission start time of the transmission failure frame, and the duration information includes information about the transmission period of the transmission failure frame.

First claim

What is claimed is:

1 . A method of reporting information about a transmission failure frame in a wireless local area network (WLAN), the method comprising:
generating, by a station (STA), a retransmission frame; and transmitting, by the STA, the retransmission frame to an access point (AP), wherein the retransmission frame includes information related to the transmission failure frame, wherein the information related to the transmission failure frame includes timestamp information and duration information, wherein the timestamp information includes information related to a transmission start time of the transmission failure frame, and wherein the duration information includes information related to a transmission duration of the transmission failure frame.

2 . The method of claim 1 , further comprising receiving, by the STA, access parameter information from the AP,
wherein the access parameter information is determined based on the information related to the transmission failure frame.

3 . The method of claim 1 , further comprising receiving, by the STA, first resource allocation information determined based on the information related to the transmission failure frame from the AP,
wherein the first resource allocation information includes at least one of time resource information and channel resource information for frame transmission of the STA.

4 . The method of claim 1 , further comprising receiving, by the STA, information for mandating transmission of a request to send (RTS) frame and a clear to send (CTS) frame from the AP.

5 . The method of claim 1 ,
wherein the information related to the transmission failure frame is used to detect a hidden node of the STA.

6 . The method of claim 1 ,
wherein the transmission failure frame is a frame not receiving acknowledgement (ACK) among frames transmitted by the STA to the AP, and wherein the retransmission frame is for retransmission of the frame.

7 . A station (STA) reporting information related to a transmission failure frame in a wireless local area network (WLAN), the STA comprising:
a radio frequency(RF) unit configured to transmit and receive a radio signal; a processor operatively connected to the RF unit and configured to: generate a retransmission frame; and transmit the retransmission frame to an access point (AP), wherein the retransmission frame comprises information related to the transmission failure frame, wherein the information related to the transmission failure frame includes timestamp information and duration information, wherein the timestamp information includes information related to a transmission start time of the transmission failure frame, and wherein the duration information includes information related to a transmission duration of the transmission failure frame.

8 . The STA of claim 7 ,
wherein the processor is further configured to receive access parameter information from the AP, and wherein the access parameter information is determined based on the information related to the transmission failure frame.

9 . The STA of claim 7 ,
wherein the processor is further configured to receive first resource allocation information determined based on the information related to the transmission failure frame from the AP, and wherein the first resource allocation information includes at least one of time resource information and channel resource information for frame transmission of the STA.

10 . The STA of claim 7 ,
wherein the processor is further configured to receive information for mandating transmission of a request to send (RTS) frame and a clear to send (CTS) frame from the AP.

11 . The STA of claim 7 , wherein the information related to the transmission failure frame is used to detect a hidden node of the STA.

12 . The STA of claim 7 ,
wherein the transmission failure frame is a frame not receiving acknowledgement (ACK) among frames transmitted by the STA to the AP, and wherein the retransmission frame is for retransmission of the frame.
