Abstract
A method for transmitting a physical layer protocol data unit (PPDU) and a device using the same are provided. The device receives a trigger frame for requesting a transmission of a response PPDU and transmits the response PPDU. A duration of the response PPDU is calculated based on a duration of the trigger frame.
Claims18
A method for transmitting a physical layer protocol data unit (PPDU) in a wireless local area network, the method being performed by a station, the method comprising:
- receiving, from an access point (AP), a trigger frame for requesting a transmission of a response PPDU, the trigger frame including a first duration field, a length field and a resource allocation field, the resource allocation field indicating a resource allocated to the transmission of the response PPDU;
- generating the response PPDU based on the trigger frame;
- and
- transmitting, to the AP, the response PPDU as a response to the trigger frame,
- wherein the response PPDU includes a second duration field, the second duration field being set to a value obtained by D1-D2,
- wherein D1 is a value obtained from the first duration field of the trigger frame,
- wherein D2 is a value obtained by:
- S
