US 2017/0325266 A1 · METHOD AND APPARATUS FOR TRANSMITTING FRAME

Abstract

Disclosed are a method and apparatus for transmitting a frame. A method for transmitting a frame in a wireless LAN comprises the steps of: an STA receiving an uplink transmission trigger frame from an access point (AP), wherein the uplink transmission trigger frame triggers the transmission of an uplink frame of an STA on an overlapping time resource, and triggers the transmission of one other uplink frame of at least one other STA; the STA transmitting the uplink frame to the access point (AP) through an allocated uplink transmission resource; and the STA performing a backoff process based on channel access parameters, which have been determined according to the success of the uplink frame transmission.

Dependent claims

A method for transmitting a frame in a wireless LAN, comprising:

receiving by a station (STA) an uplink transmission trigger frame from an access point (AP), wherein the uplink transmission trigger frame triggers a transmission of an uplink frame of the STA and a transmission of another uplink frame of at least another STA within an overlapping time resource;
transmitting by the station (STA) the uplink frame to the access point (AP) through an allocated uplink transmission resource;
and
performing by the STA a backoff procedure based on a channel access parameter being determined in accordance with a success or failure of a transmission of the uplink frame.

1 more element

A station (STA) transmitting a frame in a wireless LAN, comprising:

a radio frequency (RF) unit configured to transmit and/or receive radio signals;
and
a processor operatively connected to the RF unit,
wherein the processor is configured:
to receive an uplink transmission trigger frame from an access point (AP)
to transmit the uplink frame to the access point (AP) through an allocated uplink transmission resource, and
to perform a backoff procedure based on a channel access parameter being determined in accordance with a success or failure of a transmission of the uplink frame,
wherein the uplink transmission trigger frame triggers a transmission of an uplink frame of the STA and a transmission of another uplink frame of at least another STA within an overlapping time resource.
