Abstract
(EN)
An example according to the present specification relates to a method for performing low latency communication. A transmission STA and a reception STA may exchange a low latency communication request frame and a low latency communication response frame. The low latency communication request frame may include first information for performing the low latency communication. The first information may include at least one among information for requesting parameters for the low latency communication and information about traffic. In addition, the low latency communication response frame may include second information for performing the low latency communication. The second information may include information about the parameters for the low latency communication. The reception STA and the transmission STA may perform the low latency communication with the transmission STA on the basis of the first information and the second information.

La présente invention concerne, selon un exemple, un procédé pour effectuer une communication à faible latence. Une STA d'émission et une STA de réception peuvent échanger une trame de demande de communication à faible latence et une trame de réponse de communication à faible latence. La trame de demande de communication à faible latence peut comprendre des premières informations pour effectuer la communication à faible latence. Les premières informations peuvent comprendre des informations pour demander des paramètres pour la communication à faible latence et/ou des informations concernant le trafic. De plus, la trame de réponse de communication à faible latence peut comprendre des secondes informations pour effectuer la communication à faible latence. Les secondes informations peuvent comprendre des informations concernant les paramètres pour la communication à faible latence La STA de réception et la STA d'émission peuvent effectuer la communication à faible latence avec la STA d'émission sur la base des premières informations et des secondes informations.
