Wireless communication method and wireless communication terminal for signaling multi-user packet

A wireless communication terminal, the terminal comprising:

• a communication unit;
• and
• a processor configured to process signals transmitted and received through the communication unit,
• wherein the processor is configured to:
• receive, through the communication unit, a high efficiency multi-user PHY protocol data unit (HE MU PPDU), wherein a preamble of the HE MU PPDU includes high efficiency signal A field (HE-SIG-A) and high efficiency signal B field (HE-SIG-B), and decode the received HE MU PPDU based on information obtained from the HE-SIG-A,
• wherein a configuration of the HE-SIG-B is identified based on information obtained from at least one subfield of the HE-SIG-A, and
• wherein when a SIG-B compression field of the HE-SIG-A indicates full bandwidth Multi User-Multiple Input Multiple Output (MU-MIMQ) transmission so that a common field is not present in the HE-SIG-B, a configuration of a user specific field of the HE-SIG-B is identified based on information obtained from the at least one subfield of the HE-SIG-A.
