    摘要: A method for a power save mode operation in a wireless local area network (WLAN) system is provided. The method includes transmitting, by an access point (AP), a traffic indication map (TIM) element that announces existence of buffered traffic, wherein the TIM element includes an association ID (AID) assigned to a buffered STA having the buffered traffic when the buffered station (STA) is associated with the AP; receiving, by the AP, a poll frame for requesting data frame transmission from a candidate STA, wherein the poll frame contains an AID of the candidate STA and a medium access control (MAC) address which is a unique identifying information of the candidate STA; and determining, by the AP, whether the candidate STA is the buffered STA on the basis of the AID and the MAC address of the candidate STA.

    摘要: The present description relates to a wireless communication system, and more particularly, to a method and apparatus for uplink multiple input multiple output (MIMO) transmission. A method for performing an uplink MIMO transmission according to one embodiment of the present invention comprises the following steps: transmitting, from a first subframe, a first data block and a second data block through a first HARQ process and a second HARQ process, respectively; receiving, at a second subframe, uplink scheduling control information on the first data block and control information which indicates inactivation of the second data block; setting HARQ feedback information on the second data block to an ACK state; and performing retransmission of the first data block from a third subframe on the basis of the uplink scheduling control information on the first data block. Retransmission of the second data block may not be performed until uplink scheduling control information on the second data block is received.

    摘要: A link adaptation method performed by a station (STA) in a wireless local area network (LAN) system supporting multi-user multiple-input multiple-output (MU-MIMO) is provided. The method includes: receiving a modulation and coding scheme (MCS) request, a steered sounding physical layer convergence procedure (PLOP) protocol data unit (PPDU) which is beam-formed to the STA, and a MIMO indicator including MU-MIMO-related information from an access point (AP); and transmitting feedback information including an MCS acquired from the steered sounding PPDU and the MU-MIMO-related information to the AP in response to the MCS request.
