Claim of US Patent No. 10,484,222

7. An operation method of a wireless communication terminal, the operation method comprising:receiving a physical frame for a transmission of data to each of a plurality of wireless communication terminals comprising the wireless communication terminal from a base wireless terminal,
obtaining, from the physical frame, a signaling field which signals information on a resource allocation to the plurality of wireless communication terminals and comprises a first field which represents a different type of information according to a Multi User (MU) transmission method which is used in a sub-frequency band corresponding to the first field, wherein the sub-frequency band corresponding to the first field is one of a plurality of sub-frequency bands which are included in a frequency band through which the physical frame is transmitted, wherein the MU transmission method comprises at least one of Orthogonal Frequency Division Multiple Access (OFDMA) and Multi User-Multi Input Multi Output (MU-MIMO), wherein the first field has the same size regardless of the MU transmission method, wherein the first field represents whether the sub-frequency band corresponding to the first field is not allocated for the transmission of data to any of the plurality of wireless communication terminals, from the physical frame, and
when the OFDMA is used for the transmission of data to the plurality of wireless communication terminals, determining, based on the first field, a sub-frequency band which is allocated to the wireless communication terminal, and
obtaining data corresponding to the wireless communication terminal through the sub-frequency band which is allocated to the wireless communication terminal.
