Abstract: A method and an apparatus for transmitting a PPDU on the basis of an S-TDMA in a wireless LAN system are presented. Particularly, an AP transmits a trigger frame to a first STA and a second STA. The AP receives, on the basis of the trigger frame, a first trigger-based frame from the first STA and a second trigger-based frame from the second STA. The trigger frame includes a common information field and a user information field. The common information field includes S-TDMA indication information enabling the S-TDMA to be performed. The user information field includes: allocation information on a first RU to which the first trigger-based frame and the second trigger-based frame are transmitted; first symbol offset information on the first trigger-based frame; and second symbol offset information on the second trigger-based frame.

Abstract: A method for a wireless local area network (WLAN) system is discussed. The method includes transmitting, by a first station (STA), a trigger frame triggering uplink multi-user (UL MU) transmission from a second STA, wherein the trigger frame includes preference information related to an access category (AC) type for an aggregation frame to be generated by the second STA and limit information related to a maximum number of traffic identifiers (TIDs) for the aggregation frame; and receiving, by the first STA, a UL frame triggered by the trigger frame, wherein the UL frame is configured based on the aggregation frame and a Quality of Service (QoS) null frame which has an acknowledgement (ACK) policy field being set to no ACK, wherein the aggregation frame is generated from a plurality of QoS data frames of the second STA based on the preference information and the limit information, wherein the QoS null frame is aggregated with the aggregation frame regardless of the preference information and the limit information.

Abstract: The present document relates to a wireless communication system and, more specifically, to a method for flexibly supporting resource allocation in a wireless LAN system, and a method and an apparatus for signal transmission using the same. To this end, a first STA configures a radio frame comprising: a signaling (SIG) field including control information; and a data field in which data can be transmitted via a discontinuous channel or a channel having a bandwidth size that is supported by a legacy system. When the first STA transmits the configured radio frame to a second STA, the SIG field preferably comprises: information about a full bandwidth in which data can be transmitted via the data field; and null indicator information indicating a channel region of the full bandwidth that is not used in data transmission, or used channel indicator information indicating a channel region of the full bandwidth that is used in data transmission.
