Abstract
There is provided a method of transmitting data to multi destinations in a wireless LAN system. In the method, a transmitting device generates a media access control protocol data unit (MPDU) for each of a plurality of destination devices, and the transmitting device generates an aggregated-MPDU (A-MPDU) by sequentially adding the MPDU for each of the destination devices. A physical header is added to the A-MPDU, and then the A-MPDU with the physical head added is transmitted to the plurality of destination devices at the transmitting device. The respective destination device transmits ACK frames, which notify a successful reception, to the transmitting device after receiving a self-destined MPDU from the A-MPDU and verifying the received MPDU. The transmitting device receives the ACK frames transmitted from the respective destination devices in sequence.
