Abstract: 무선랜시스템에서 STA(Station)이상향링크 OFDMA 기반으로 AP(Access Point)에랜덤액세스를수행하는방법이제안된다. 이를위해 STA은 CWO (OFDMA Contention Window) 내의임의의값으로 OBO (OFDMA Back-off) 값을설정하고, AP로부터하나이상의랜덤액세스용트리거프리임(Trigger Frame For Random Access: TF-R)의전송시작시간정보를포함하는비콘프레임(Beacon Frame)을수신하고, 상기하나이상의 TF-R 수신에기반하여 OBO 값을감소시키며, OBO 값이 0에도달하는경우, 상기 STA에할당된자원중 임의로선택된자원을통해랜덤액세스요청프레임을전송한다.
Abstract translation: 在无线LAN系统中，STA（站）不是基于上行链路OFDMA执行对接入点（AP）的随机接入的方法。 为此，STA在CWO（OFDMA竞争窗口）中将OBO（OFDMA回退）值设置为任意值并且发送用于随机接入的触发帧（TF-R） 并且接收包括开始时间信息的信标帧，基于至少一个TF-R接收减小OBO值，并且当OBO值达到0时， Lt帧的帧。

Abstract: The present document relates to a wireless communication system and, more particularly, to a method for performing retransmission in a wireless LAN system to which transmission opportunity (TXOP) sharing is applied, and a device therefor. To this end, a station transmits an initial transmission frame including primary access category (AC) information and secondary access category (AC) information; and when there is no response to the secondary AC information of the initial transmission frame, reconfigures a back-off timer value for the secondary AC information and retransmits the secondary AC information according to the reconfigured back-off timer value.

Abstract: The present document relates to a method for efficiently performing uplink multi-user transmission in a wireless LAN system and an apparatus therefor. To this end, an access point (AP) may transmit a downlink multi-user frame to a plurality of STAs, receive an uplink frame including an acknowledgement/non-acknowledgement (ACK/NACK) signal for the downlink multi-user frame and an uplink scheduling request signal from at least two STAs among the STAs, transmit a downlink frame including uplink scheduling information to the at least two STAs on the basis of the uplink scheduling request signal, and receive an uplink multi-user frame including data from the at least two STAs in response thereto. Here, an SIG field of the downlink frame preferably comprises an indicator indicating that the downlink frame includes uplink multi-user scheduling information.

Abstract: The present disclosure relates to a method of receiving, by a station that operates in a wireless LAN system, a signal in a wireless communication system. In this case, it is possible to include the steps of receiving a PPDU that includes an MAC frame, decoding the MAC frame, and checking information in the MAC frame based on the MAC header of the MAC frame that includes a first address field and a second address field. In this case, when the PPDU includes the identification information (ID) of a station, the MAC header may include only one of any of the first address field and the second address field.
