Method and apparatus for allocating wireless resources according to resource allocation setting in WLAN
First Claim
1. A method of allocating a plurality of radio resources for downlink multi-user (DL MU) transmission in a wireless local area network (WLAN), the method comprising:
- transmitting, by an access point (AP), resource allocation setup information to a plurality of stations (STAs), wherein the resource allocation setup information indicates whether the plurality of radio resources corresponding to an entire bandwidth for the plurality of STAs are allocated based on first resource units or second resource units, and wherein the second resource units have a size larger than that of the first resource units;
allocating, by the AP, the plurality of radio resources for the plurality of STAs individually according to the resource allocation setup information;
transmitting, by the AP, a downlink physical (PHY) protocol data unit (PPDU) including a plurality of downlink data to the plurality of STAs,wherein the downlink PPDU includes resource allocation information to indicate the plurality of radio resources individually allocated for the plurality of STAs,wherein the resource allocation information is included in a PHY header of the downlink PPDU, andwherein the plurality of downlink data are individually transmitted through the plurality of radio resources; and
receiving, by the AP, channel feedback information related to the plurality of radio resources from the plurality of STAs respectively.

Abstract
Disclosed are a method and an apparatus for allocating wireless resource according to a resource allocation setting in a WLAN. The method for allocating wireless resources according to the resource allocation setting, in a WLAN, may comprise the steps of: an AP transmitting, to a plurality of STAs, resource allocation setting information; the AP allocating, to each of the plurality of STAs, each of the plurality of wireless resources in first resource units or second resource units, based on the resource allocation setting information; the AP transmitting to each of the plurality of STAs, through each of the plurality of wireless resources, each of a plurality of items of downlink data; and the AP receiving, from each of the plurality of STAs, channel feedback information for each of the plurality of wireless resources.
