Abstract: 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.

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: 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.
