A method for transmitting and receiving frames performed by a station (STA) in power save mode in a wireless local area network is provided. The method includes: transmitting a Power Save (PS) poll frame to an access point (AP) in a first 20MHz channel; transmitting at least one duplicated PS poll frame to the AP in at least one second 20MHz channel, the at least one duplicated PS poll frame being generated by duplicating the PS poll frame; and receiving a bufferable frame from the AP as a response of at least one of the PS poll frame and the at least one duplicated PS poll frame. |
