A frame transmission method is provided by a device in a wireless communication network. The device generates a signal field including a symbol using a 64 FFT and carrying signaling information, and generates a data field including a symbol using a FFT having a larger size than the 64 FFT and carrying data. The device transmits a frame including the signal field and the data field.

Method for transmitting and receiving frame

A method for interference aware communications of devices in a wireless local area network is provided. The device selects a transmission channel of a frame among a plurality of sub-channels, generates interference aware information based on an interference condition of the plurality of sub-channels, inserts the interference aware information into the frame, and transmits the frame in the selected transmission channel.

Method and apparatus for interference aware communications

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.

Transmission method

A method for transmitting frames of a device in a wireless local area network (WLAN) includes generating a symbol in which legacy cyclic prefixes are periodically located and transmitting a frame including the symbol, wherein the symbol includes a data duration excluding cyclic prefix in symbol duration, and the length of the data duration is longer than 3.2 us.

Method for transmitting frame, clear channel assessment method, and apparatus implementing the same 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

A method of transmitting a frame is provided by a first device belonging to a first BSS in a wireless communication network. The first device determines whether an RTS frame or a CTS frame is received from a second BSS that is a neighbor BSS of the first BSS. When the RTS frame or the CTS frame is received from the second BSS, the first device transmits to a second device a transmission frame whose transmission power is changed from a normal power during a predetermined time within a data frame transmission time and an ACK frame transmission time of the second BSS.

Frame transmitting method

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.
