Wireless communication method and wireless communication terminal, which use discontinuous channel

A wireless communication terminal, the terminal comprising:

• a processor;
• and
• a communication unit,
• wherein the processor is configured to:
• receive a wireless packet including an High Efficiency Signal A(HE-SIG-A) field and an High Efficiency Signal B(HE-SIG-B) field through the communication unit,
• obtain bandwidth information indicated by a bandwidth field included in the HE-SIG-A field,
• obtain information of an unassigned resource unit by a subfield included in the HE-SIG-B field,
• wherein the bandwidth field is related to bandwidth over which the received wireless packet is transmitted, and is used to obtain the information of the unassigned resource unit, and
• decode a data of the received wireless packet based on the bandwidth information and the information of the unassigned resource unit,
• wherein when the received wireless packet is transmitted in a total bandwidth of 80 MHz or more, the information of the unassigned resource unit includes information of a C26 field indicating whether a user is allocated to a center 26-tone resource unit of 80 MHz.

A wireless communication method of a wireless communication terminal, the method comprising:

• receiving a wireless packet including an high efficiency(HE)-signal(SIG)-A and HE-SIG-B through the communication unit;
• obtaining bandwidth information indicated by a bandwidth field included in the HE-SIG-A;
• obtaining information of an unassigned resource unit by a subfield included in the HE-SIG-B,
• wherein the bandwidth field is related to bandwidth over which the received wireless packet is transmitted, and
• wherein the bandwidth field of HE-SIG-A is used to obtain the information of the unassigned resource unit;
• and
• decoding a data of the received wireless packet based on the total bandwidth information and the information of the unassigned resource unit,
• wherein when the received wireless packet is transmitted in a total bandwidth of 80 MHz or more, the information of the unassigned resource unit includes information of a C26 field indicating whether a user is allocated to a center 26-tone resource unit of 80 MHz.
