Abstract: Disclosed are a method and an apparatus for retransmission in a wireless LAN. The method for retransmission in a wireless LAN may comprise the steps in which: an STA receives an RTS frame from an AP; the STA transmits a CTS frame to the AP in response to the RTS frame; the STA receives an initial data frame from the AP after transmitting the CTS frame; if decoding on the initial data frame is impossible, the STA transmits a retransmission request frame to the AP; and the STA receives a retransmission data frame from the AP in response to the retransmission request frame.

Abstract: The present document relates to a method for transmitting and receiving signals by controlling interference on other wireless devices based on actual transmitted power or received power information in a wireless communication system, and an apparatus therefor. To this end, STA 1 receives from STA 2 a frame comprising power information about actual transmitted power or actual received power of STA 2. Through the frame, STA 1 determines transmitted power by correcting the existing transmitted power of STA 1 by using the power information of STA 2 and, when the determined transmitted power of STA 1 is less than or equal to a reference value, transmits signals through the frame.
