Abstract
Uplink transmission in a wireless local area network is provided. A station receives a trigger frame for requesting a transmission of an uplink physical layer protocol data unit (PPDU) from an access point (AP). The station determines a value of a second duration field of an uplink PPDU based on a first duration field of the trigger frame. The station transmits the uplink PPDU. The uplink PPDU does not include any frame that solicits a response frame from the AP when the value of the second duration field is set to zero.
