Abstract: The present invention relates to a method and apparatus for dynamically allocating resources in a High Efficiency WLAN (Wireless Local Area) (HEW). According to one aspect of the present invention, a method for resource switching in a WLAN may be provided. The method may include receiving, by a station (STA) from an access point (AP), a downlink multiple user (DL MU) frame on a resource indicated by first resource allocation information, the DL MU frame including the first resource allocation information and second resource allocation information for a next MU frame following the DL MU frame, and processing, by the STA, the next MU frame based on a resource indicated by the second resource allocation information.

Abstract: The present invention provides a method and apparatus for transmitting a downlink ACK in response to an uplink multi-user transmission in a HE WLAN. In an aspect of the present invention, a method for transmitting an ACK in response to uplink data received from a plurality of STAs by an AP in a WLAN may be provided. The method may include transmitting a frame triggering transmission of a plurality of uplink data units from the plurality of STAs to the plurality of STAs, receiving a PPDU frame including a plurality of uplink data units from the plurality of STAs a predetermined IFS after transmitting the trigger frame, and transmitting an ACK frame including ACKs for the plurality of data units from the plurality of STAs.
