Abstract: Provided are a frame transmission method performed in an access point (AP), a frame reception method performed in a terminal, and an AP. The frame transmission method performed in an AP includes acquiring a channel for transmitting a first data unit of a first terminal, when a data unit to be transmitted to at least one terminal other than the first terminal is in the AP, generating a physical layer convergence procedure (PLCP) protocol data unit (PPDU) including the first data unit and the data unit to be transmitted to the at least one terminal, and transmitting the PPDU to the first terminal and the at least one terminal. Accordingly, it is possible to improve the performance of a wireless local area network (WLAN).
