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.
Claims15
A method of performing uplink transmission, which is performed by an STA (station) in a wireless communication system, comprising the steps of:
- receiving a trigger frame from an AP (Access Point) including an indication field indicating whether a carrier sensing is required;
- and
- considering both a result of CCA (Clear Channel Assessment) and NAV(Network Allocation Vector) when the indication field indicates that the carrier sensing is required, and
- performing uplink transmission when a result of the considering both the result of CCA and the NAV is IDLE or the indication field indicates that the carrier sensing is not required.
(canceled)
An STA (station) performing uplink transmission in a wireless communication system, comprising:
- a transceiver;
- and
- a processor, the processor configured to receive a trigger frame including an indication field indicating whether a carrier sensing is required from an AP, the processor configured to consider both a result of CCA (Clear Channel Assessment) and NAV(Network Allocation Vector) when the indication field indicates that the carrier sensing is required, and the processor configured to perform uplink transmission when a result of the considering both the result of CCA and the NAV is IDLE or the indication field indicates that the carrier sensing is not required.
