1. A wireless communication terminal, the terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to:
receive a preamble of a wireless frame through the transceiver,
wherein the preamble comprises a L-STF(Legacy Short Training Filed), a L-LTF(Legacy Long Training Field), a L-SIG(Legacy Signal Field) and a specific SIG field,
wherein the specific SIG field includes a specific index among a plurality of indices,
wherein each of the plurality of indices corresponds to each of pre-configured resource unit sets including a plurality of resource units and a pre-configured number of at least one terminal for each of the pre-configured resource unit sets,
wherein sizes of two or more resource units among the plurality of resource units included in a specific resource unit set are different from each other when the specific resource set among the pre-configured resource unit sets is indicated by the specific index among the plurality of indices, and
wherein each of two or more terminals is allocated to the plurality of resource units indicated by the specific index when the two or more terminals are indicated by the specific index among the plurality of indices, and
receive a data based on a pre-configured resource unit set for the plurality of resource units and the pre-configured number of the at least one terminal indicated by the specific index.
