[0150] Hereinafter, a method for transmitting UL data by STAs in a station group during a PSMP process using station group information and UL resource allocation information allocated to each station group will be described according to the first embodiment of the present invention.

[0151] Figure 12 (a) to Figure 12 (c) shows the PSMP procedure according to the first embodiment of the present invention.

[0152] Such as Figure 12 (a) to Figure 12 As shown in (c), the PSMP operation process in the WLAN system includes the PSMP frame sending phase, the DL phase, the UL phase and the contention phase. That is, by newly defining a competition phase, the competition phase only allows STAs in a station group including at least one STA to transmit data to the AP by competing with other STAs in the station group. In this case, the advantage is that possible collisions can be reduced when the WLAN system has many STAs and all STAs participate in contention.

Abstract

The present description relates to a method in which a station transmits data in a wireless LAN system, comprising the following steps: receiving, from an access point, control information containing station group configuration information, which indicates the configurations of station groups and uplink resource allocation information on the resource allocated to each station group; determining, on the basis of the control information, the station group to which the station belongs; and transmitting uplink data to the access point by contending with other stations in the determined station group.

Description

technical field [0001] The present invention relates to a wireless local area network (WLAN), and more particularly, to a method and device for sending and receiving data by allocating resources to a station group. Background technique [0002] With the development of information communication technology, various wireless communication technologies have been developed recently. Among these wireless communication technologies, wireless local area network (WLAN) is the use of portable terminals such as personal digital assistants (PDAs), laptop computers, portable multimedia players (PMPs), etc. technology for wireless Internet access in an area. [0003] Since the establishment of the Institute of Electrical and Electronics Engineers (IEEE) 802, ie, a standardization organization for WLAN technology, in February 1980, much standardization work has been performed. In the original WLAN technology, according to IEEE 802.11, a frequency of 2.4 GHz is used to support a data rate...
