Method and apparatus for classifying low latency traffic in wireless lan system

An apparatus comprising:

• at least one transceiver;
• and
• at least one processor connected to the at least one transceiver,
• wherein the at least one processor is configured to:
• transmit a request frame for a stream classification service (SCS) process;
• and
• receive a response frame for the request frame,
• wherein at least one of the request frame or the response frame includes first information indicating an SCS ID and second information indicating an LL-related ID for classification of low latency (LL) traffic.
