1. A frame transmission method performed in an access point (AP), the method comprising:
acquiring a channel for transmitting a first data unit of a first terminal;
when a second data unit to be transmitted to a second terminal which is associated with the AP, generating a physical layer convergence procedure (PLCP) protocol data unit (PPDU) including the first data unit and the second data unit; and
transmitting the PPDU to the first terminal and the second terminal,
wherein the first data unit and the second data unit are multiplexed in a frequency domain, the first data unit of the PPDU is transmitted through a first frequency channel in the frequency domain, the second data unit of the PPDU is transmitted through a second frequency channel in the frequency domain, and the PPDU includes a first identifier of the first terminal to receive the first data unit, a second identifier of the second terminal to receive the second data unit, information indicating the first frequency channel through which the first data unit is transmitted, and information indicating the second frequency channel through which the second data unit is transmitted.
