Method and apparatus for configuring a signal field including allocation information for a resource unit in wireless local area network system

A station in a wireless local area network (WLAN), comprising:

• a transceiver transmitting or receiving radio signals;
• and
• a processor connected to the transceiver and configured to:
• instruct the transceiver to receive, a physical layer protocol data unit (PPDU) comprising a first control field including common control information, a second control field including a user common field and a user specific field, and a data field, wherein the user common field includes allocation information for a first resource unit (RU) corresponding to 106 subcarriers and a second RU corresponding to 106 subcarriers, wherein the user common field includes a first number bit indicating a number of multiple user-multiple input multiple output (MU-MIMO) users allocated to the first RU and a second number bit indicating a number of MU-MIMO users allocated to the second RU, wherein each of the first and second number bits is implemented with 2 bits, wherein the user specific field includes first identification information for the MU-MIMO users allocated to the first RU and second identification information for the MU-MIMO users allocated to the second RU;
• determine at least one resource unit (RU) allocated for the receiving station by using the second control field;
• and
• decode the data field by using the at least one RU.
