Abstract
Provided are a method and apparatus for transmitting/receiving a signal based on a power saving (PS) mode in a wireless local area network (WLAN) system. Specifically, a first station (STA) determines the PS mode in a time division duplex (TDD)-based service period (SP), and transmit the signal to the second STA or receive the signal from the second STA based on the PS mode. The SP includes a plurality of TDD slots. The plurality of TDD slots include an unassigned TDD slot, an assigned Tx TDD slot, and an assigned Rx TDD slot. In the unassigned TDD slot, a PS mode of the first STA is determined as a doze state, and a PS mode of the second STA is determined an awake or doze state. In the assigned Rx TDD slot, the PS mode of the first STA is determined as the awake state, and the PS mode of the second STA is determined as the awake state. In the assigned Tx TDD slot, the PS mode of the first STA is determined as the awake or doze state, and the PS mode of the second STA is determined as the awake state.
