US 2019/0174484 A1 · METHOD FOR TRANSMITTING A RESPONSE REQUEST FRAME AND A RESPONSE FRAME IN A MULTI-USER BASED WIRELESS COMMUNICATION SYSTEM

Abstract

The present invention relates to a method for efficient transmission of a request frame such as an RTS/CTS frame and a response frame in response to the request frame in a multi-user based wireless communication system. The method of the present invention comprises: a process where wireless terminals transmit a response frame at their own response frame transmission time through a request frame that contains information about a plurality of wireless terminals and information about the response frame transmission time of the respective wireless terminals; a process where the respective wireless terminals transmit a response frame according to a token scheme such that the response frame is transmitted to a final access point; and a process where only a representative wireless terminal selected depending on a given wireless environment receives the response frame.

Claims6

Dependent claims

A method of transmitting a response frame in a wireless communication system, the method comprising:

receiving, by a first station, from an access point, a request frame for requesting channel information to the first station and a second station, the request frame including time information, a first user field identifying the first station and a second user field identifying the second station;
and
transmitting, by the first station, to an access point, a response frame as a response to the request frame,
wherein the time information is determined based on a sum of an estimated time required for the first station to transmit the response frame plus at least one Short Interframe Space (SIFS), and
wherein the request frame sequentially includes the time information, the first user field and the second user field.
