Abstract
A method for UL MU transmission of an STA operating in a power save mode comprises the steps of: transmitting a TWT request element including first information related to a requested TBTT of a first beacon frame and second information related to a requested wake interval between subsequent beacon frames the STA intends to receive to an AP; receiving a TWT response element from the AP in response to the TWT request element; switching to a doze state from the awake state after receiving the TWT response element; switching to the awake state from the doze state based on the third information in order to receive the first beacon frame from the AP; receiving the first beacon frame including fifth information related to a trigger transmission time of a trigger frame soliciting the UL MU transmission from one or more STAs from the AP.
