1. A method performed by a station (STA) in a wireless local area network (WLAN) system, the method comprising:
receiving information related to a restricted-target wake time (R-TWT) service period (SP) from an access point (AP); and
setting at least one R-TWT traffic identifier (TID) for the R-TWT SP, through a membership setup procedure between the STA and the AP,
wherein a frame exchange based on the at least one R-TWT TID is performed during the R-TWT SP, and
wherein, based on a pre-defined channel access rule, a back-off operation for an access category (AC) mapped with none of the at least one R-TWT TID is suspended during the R-TWT SP.
