1. A method performed by a receiving station (STA) in a wireless local area network system, the method comprising:
receiving information on an inter-frame space (IFS) for low-latency data,
wherein the inter-frame space for the low-latency data is configured to be larger than a Point Coordination Function Inter-frame Space (PIFS) and smaller than a Distributed Inter-Frame Space (DIFS);
performing channel access through an Enhanced Distributed Channel Access (EDCA) based on the inter-frame space for the low-latency data; and
transmitting the low-latency data based on the channel access.
