Abstract
One embodiment of the present invention relates to a method by which a station (STA) performs uplink transmission in a wireless communication system, the method for performing uplink transmission comprising the steps of: receiving a trigger frame from an AP; and performing uplink transmission as a response to the trigger frame, wherein, when a network allocation vector (NAV) of the STA receiving the trigger frame is idle and clear channel assessment (CCA) result is idle, the uplink transmission is performed.
Claims18
A method of performing uplink transmission, by an STA (station), in a wireless communication system, the method comprising:
- receiving, by the STA, a trigger frame triggering transmission of the response frame from an AP (Access Point);
- and
- transmitting, by the STA, the response frame to the AP,
- wherein the response frame is transmitted without a CCA (clear channel assessment) based on a length of the response frame equal to or less than a threshold.
An STA (station) performing uplink transmission in a wireless communication system, the STA comprising:
- a transceiver;
- and
- a processor, the processor configured to receive a trigger frame triggering transmission of the response frame from an AP (Access point),
- wherein the processor is further configured to transmit the response frame to the AP,
- wherein the response frame is transmitted without a CCA (clear channel assessment) based on a length of the response frame equal to or less than a threshold.
