Abstract: A method of transmitting data in a wireless local access network, the method includes transmitting, by an access point (AP), a request-to-send (RTS) frame to a plurality of receiving stations, the RTS frame including recipient information and channel information, the recipient information indicating the plurality of receiving stations, the channel information indicating a plurality of subchannels allocated to the plurality of receiving stations; receiving, by the AP, a plurality of clear-to-send (CTS) frames from the plurality of receiving stations as a response to the RTS frame, each CTS frame being received through at least one subchannel allocated to a corresponding one of the plurality of receiving stations; and transmitting, by the AP, a physical layer protocol data unit (PPDU) to the plurality of receiving stations, the PPDU including address information indicating the plurality of receiving stations and a plurality of Aggregate-Medium Access Control (MAC) Protocol Data Units (A-MPDUs) for the plurality of receiving stations.

Abstract: A method of transmitting data in a wireless local access network, the method comprising: transmitting, by an access point, a downlink management frame to a plurality of recipients, the downlink management frame including information about a group address indicating a station group to which the plurality of recipients belongs; transmitting, by the access point, a data frame to the plurality of recipients, the data frame including the group address and a plurality of Aggregate-Medium Access Control (MAC) Protocol Data Units (A-MPDUs) for the plurality of recipients, wherein each of the plurality of A-MPDUs includes at least one MPDU for a corresponding one of the plurality of recipients, and wherein each of the plurality of A-MPDUs further includes zero or more padding bits so that all of the plurality of A-MPDUs have the same transmission time corresponding to a transmission time of a longest A-MPDU among the plurality of A-MPDUs.
