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.

Transmission control method

In a WLAN, a device receives a frame where a symbol is attached to a previous version frame, the symbol including BSS information. The device determines whether the device belongs to a BSS of the frame based on the BSS information.

Method and apparatus for transmitting and receiving frame

In a WLAN, a device generates a short training field and a long training field following the short training field. The device generates a first signal field following the long training field, and the first signal field includes a mode field for indicating a transmission mode of a frame to be transmitted and a check bit for protecting at least the mode field. The device transmits the frame including the short training field, the long training field, and the first signal field.

Method for transmitting frame and method for detecting transmission mode

A signaling method is provided by a device in a WLAN. The device includes signaling information in an address field, generates a MAC frame including the address field, and transmits a PHY frame including a data field into which the MAC frame is inserted.

Signaling method

An interleaving method by a transmitting device is provided. The transmitting device divides a bandwidth into a plurality of bands, and divides an interleaver matrix into a plurality of matrices corresponding to the plurality of bands respectively in a predetermined direction. Next, the transmitting device arranges data of a user assigned to a corresponding band among the plurality of bands in each matrix of the plurality of matrices.
