METHOD FOR PERFORMING OPERATION IN ACCORDANCE WITH POWER SAVE MODE IN WIRELESS LAN SYSTEM AND WIRELESS TERMINAL USING SAME

摘要

A method for performing an operation in accordance with a PS mode in a wireless LAN system comprises the steps of: performing a receiving operation for an EDMG MU PPDU, wherein the EDMG MU PPDU includes a preamble and a plurality of A-MPDUs having the same length transmitted on an overlapped time resource, the preamble includes first order information on a transmission order of a first block ACK frame for a first A-MPDU to be transmitted to a first STA among the plurality of A-MPDUs, and the transmission order is determined according to a length of a data area included in the first A-MPDU; converting a power state of the first STA into a doze state at a first time when the reception of the first data area included in the first A-MPDU is finished, if it is determined that the transmission order of the first block ACK frame is not the first on the basis of the first order information; maintaining, as the doze state, the power state from the first time to a second time; and converting the power state into an awake state after the second time elapses.
