Abstract:
1. A method for transmitting data in a wireless local area network, the method comprising: establishing, by a source station, a direct link with a destination station; establishing, by the source station, a relay link with a relay station that relays physical layer protocol data units (PPDUs) between the source station and the destination station; transmitting, by the source station, a first PPDU to the destination station via the direct link; and after transmitting the first PPDU and switching from the direct link to the relay link, transmitting, by the source station, a second PPDU to the relay station via the relay link so that the relay station forwards the second PPDU to the destination station, wherein the first PPDU includes a sequence field indicating that the second PPDU will be transmitted via the relay link, and wherein the relay link is established with the relay station by: transmitting, by the source station, a relay request message to the relay station to request a setup for the relay link, the first relay request message including information about an association identifier (AID) of the relay station and an AID of the destination station; and receiving, by the source station, a relay response message from the relay station to indicate that the relay station is willing to participate in the relay link.
