Abstract: In a WLAN, a device sets a first NAV to a bandwidth used by a signal from a second device. The device selects a channel that does not correspond to the bandwidth from among a plurality of channels when a predetermined condition is satisfied. The predetermined condition includes a condition that the first NAV is set. The device transmits a first frame on the selected channel.

Abstract: A sounding method by a receiving device is provided. The receiving device receives an NDPA frame from a transmitting device, and then receives an NDP frame from the transmitting device. After receiving the NDP frame, the receiving device transmits to the transmitting device a feedback frame including subchannel information measured on a subchannel that is allocated to the first receiving device among a plurality of subchannels into which a predetermined band is divided.

Abstract: Disclosed are a method and an apparatus for transmitting and receiving data in a Wireless Local Area Network (WLAN) system. A method for transmitting data may comprise generating a physical layer (PHY) frame including a payload in which a plurality of Medium Access Control protocol data units (MPDUs) are multiplexed; and transmitting the PHY frame, wherein the PHY frame includes information on subcarriers occupied by each of the plurality of MPDUs in an Orthogonal Frequency Division Multiplexing (OFDM) symbol of the payload. Therefore, data transmission efficiency in a WLAN system can be enhanced.

Abstract: An Acknowledgment (ACK) method is provided by a receiving device in a Wireless Local Area Network (WLAN). The receiving device receives a plurality of data units having a plurality of Traffic Identifiers (TIDs) and transmits an ACK frame including a plurality of ACK information fields for at least part of the plurality of data units. An ACK information field for a data unit satisfying a first condition among the plurality of ACK information fields includes a Traffic Identifier (TID) and a block ACK bitmap indicating whether the data unit has been successfully received. An ACK information field for a data unit satisfying a second condition and having been successfully received among the plurality of ACK information fields includes the first TID and does not include a block ACK bitmap.

Abstract: Disclosed are methods and apparatuses for transmitting and receiving a frame in a WLAN. A method for transmitting a frame, performed in a first station, may comprise receiving a first PPDU; determining whether a BSS of the first PPDU is a BSS to which the first station belongs or a BSS to which the first station does not belong; when the BSS of the first PPDU is the BSS to which the first station does not belong and a received signal strength of the first PPDU is higher than a first threshold, setting a virtual carrier sensing by using information included in a preamble of the first PPDU. Therefore, performance of the WLAN can be enhanced.

Abstract: A transmission control method by a device belonging to a BSS is provided in a WLAN. The device receives a frame. When a transmission condition including a first condition that a BSS color of the frame indicates a neighbor BSS of the BSS is satisfied, the device attempts a transmission at a time between a detection time of the BSS color and an end time of the frame.
