Abstract: A method and an apparatus for a station (STA) to save power in a wireless local area network (WLAN) are provided. For this, the STA receives a MU PPDU (Multi-User Physical Protocol Data unit) comprising A-MPDU (Aggregated MAC Protocol Data Unit) from an AP (Access Point). The STA enters into a doze state until an end of the MU PPDU, when a receiver address of the A-MPDU is equal to the STA's address, and there is an indication indicating a start of EOF (End-Of-Frame) padding.

Abstract: Disclosed are a method and an apparatus for retransmission in a wireless LAN. The method for retransmission in a wireless LAN may comprise the steps in which: an STA receives an RTS frame from an AP; the STA transmits a CTS frame to the AP in response to the RTS frame; the STA receives an initial data frame from the AP after transmitting the CTS frame; if decoding on the initial data frame is impossible, the STA transmits a retransmission request frame to the AP; and the STA receives a retransmission data frame from the AP in response to the retransmission request frame.
