Abstract
Provided is a wireless communication terminal that communicates wirelessly. The terminal includes: a transceiver; and a processor. The processor is configured to receive a trigger frame for triggering that a frame for setting a link with a wireless communication terminal, which is an AP, is transmitted through UpLink Multi User (UL MU) transmission through the transmission/reception unit. The processor transmits the frame for setting the link through UL MU transmission based on the trigger frame.
Claims16
A wireless communication terminal communicating wirelessly, the terminal comprising:
- a transceiver configured to receive and transmit a wireless signal;
- and
- a processor,
- wherein the processor is configured to:
- receive, through the transceiver, a first trigger frame from a base wireless communication terminal, wherein the first trigger frame triggers a transmissions of the wireless communication terminal,
- transmit, through the transceiver, a first response frame including a traffic or data for a specific access category in response to the first trigger frame to the base wireless communication terminal, and
- stop enhanced distributed channel access function (EDCAF) of access category (AC) which corresponds to the traffic or data when the wireless communication terminal receives an ACK for the first response frame, wherein the EDCAF is a function for determining a time at which the traffic or data in a queue is transmitted in a contention procedure and is defined per access category.
An operation method of wireless communication terminal communicating wirelessly, the method comprising:
- receiving a first trigger frame from a base wireless communication terminal, wherein the first trigger frame triggers a transmissions of the wireless communication terminal;
- transmitting a first response frame including a traffic or data for a specific access category in response to the first trigger frame to the base wireless communication terminal;
- and
- stopping enhanced distributed channel access function (EDCAF) of access category (AC) which corresponds to the traffic or data when the wireless communication terminal receives an ACK for the first response frame, wherein the EDCAF is a function for determining a time at which the traffic or data in a queue is transmitted in a contention procedure and is defined per access category.
