A communication method that includes transmitting a power save multi-poll (PSMP) frame containing a power save mode (PSM) of a non-access point (AP) station (STA) to a first station and to a second station which are paired with an AP on the basis of multiple input multiple output (MIMO) technology. Information on the PSM indicates the point in time of starting a downlink transmission period, the duration of the downlink transmission period, and transmission object station identification information. The method further involves transmitting a data frame to the first station and to the second station on the basis of the MIMO technology during the downlink transmission period. The transmission object station identification information indicates a group identifier for indicating an object station group including the first station and the second station.
