Wireless communication terminal and wireless communication method for multi-user uplink transmission

A wireless station (STA), the STA comprising:

• a transceiver;
• and
• a processor,
• wherein the processor is configured to:
• receive a trigger frame soliciting multi-transmission to one or more STAs from an access point (AP),
• wherein the trigger frame includes at least one resource allocation field allocating an resource unit for the one or more STAs and at least one association identifier (AID) field assigning an AID, and
• transmit a data frame based on a resource unit allocated to the STA by the at least one resource allocation field and an AID assigned to the STA by the at least one AID field,
• wherein a value of an AID assigned by the at least one AID field is set within a different range based on a type of the one or more STAs.
