Classification: CPC H | IPC H

Claim 0:
1. A method for a first station (STA) to communicate with a second STA in a wireless local area network (WLAN), the method comprising:
receiving, by the first STA from the second STA, resource allocation information for a plurality of STAs, including the first STA, wherein the first STA communicates with the second STA using orthogonal frequency divisional multiple access (OFDMA) or multi-user multiple input multiple output (MU-MIMO); and
receiving, by the first STA from the second STA, data through a frequency band based on the resource allocation information,
wherein the frequency band includes a plurality of resource units, the plurality of resource units including a normal resource unit allocated to one STA, and a multi-user resource unit which is a single resource unit allocated to more than one STA among the plurality of STAs,
wherein the resource allocation information includes:
a common resource allocation information having a same value for the plurality of STAs, and informing a number of the plurality of resource units and each size of the plurality of resource units,
a multi-user indication for a number of STAs, among the plurality of STAs, to which the multi-user resource unit is allocated, and
multiple ID fields for corresponding identification information of STA to which the normal resource unit or the multi-user resource unit is allocated.
