Abstract

A method and apparatus operating in a wireless LAN system are disclosed. According to one embodiment of the disclosure, a method performed by a first station (STA) in a wireless LAN system can include receiving a first frame including first information related to a low latency traffic (LLT) target wake time (TWT) schedule from an access point (AP), transmitting a TWT request frame related to membership for the LLT TWT schedule to the AP, receiving a TWT response frame from the AP based on the TWT request frame, and transmitting a first LLT and / or second information related to the first LLT to the AP within a service period (SP) related to the first information.
