Abstract: The specification proposes a method for requesting information on a restricted TWT when an STA has failed to receive the information. According to an embodiment of the present specification, when an STA fails to acquire information on a restricted TWT, the STA may transmit, to an AP, a signal for requesting the information on the restricted TWT after a certain time elapses from a TBTT. The signal may be transmitted independently or may be transmitted together with another signal transmitted by the STA.
