A method for a non-access point station, non-AP STA, to communicate with an access point, AP, using orthogonal frequency divisional multiple access, OFDMA, or multi-user multiple input multiple output, MU-MIMO in a wireless local area network, WLAN, the method comprising: receiving a physical protocol data unit, PPDU, from the AP, wherein the PPDU comprises a signaling, SIG, field including resource allocation information for a plurality of non-AP STAs and data field received 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 non-AP STA, and a multi-user resource unit which is a single resource unit allocated to more than one non-AP STA among the plurality of non AP STAs, wherein the resource allocation information includes: a common resource allocation information having a same bit sequence value for the plurality of non-AP STAs, and the same bit sequence value informing of a number of the plurality of resource units and various size of each of the plurality of resource units, multi-user indication for a number of non-AP STAs, among the plurality of non-AP STAs, to which the multi-user resource unit is allocated, and multiple ID fields for corresponding identification information of non-AP STA to which the normal resource unit or the multi-user resource unit is allocated. receiving a physical protocol data unit, PPDU, from the AP, wherein the PPDU comprises a signaling, SIG, field including resource allocation information for a plurality of non-AP STAs and data field received 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 non-AP STA, and a multi-user resource unit which is a single resource unit allocated to more than one non-AP STA among the plurality of non AP STAs, wherein the resource allocation information includes: a common resource allocation information having a same bit sequence value for the plurality of non-AP STAs, and the same bit sequence value informing of a number of the plurality of resource units and various size of each of the plurality of resource units, multi-user indication for a number of non-AP STAs, among the plurality of non-AP STAs, to which the multi-user resource unit is allocated, and multiple ID fields for corresponding identification information of non-AP STA to which the normal resource unit or the multi-user resource unit is allocated. a common resource allocation information having a same bit sequence value for the plurality of non-AP STAs, and the same bit sequence value informing of a number of the plurality of resource units and various size of each of the plurality of resource units, multi-user indication for a number of non-AP STAs, among the plurality of non-AP STAs, to which the multi-user resource unit is allocated, and multiple ID fields for corresponding identification information of non-AP STA to which the normal resource unit or the multi-user resource unit is allocated. <EOS>
