Patent ID: 11910436
Assignee: WILUS INSTITUTE OF STANDARDS AND TECHNOLOGY INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 3:
4. A wireless communication terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to:
receive, by using the transceiver, a first non-data frame from a base wireless communication terminal, simultaneously with at least one of a first plurality of wireless communication terminals, wherein the first non-data frame reserves a Transmit Opportunity (TXOP), and allocates a channel for a second non-data frame which is a response to the first non-data frame to each of the wireless communication terminal and the first plurality of wireless communication terminals using a plurality of channel fields of the first non-data frame, wherein each of the plurality of channel fields includes a first subfield for an association identifier (AID) and a second subfield for an index indicating predetermined channel usage pattern for a frequency band range, wherein the first subfield indicates a wireless communication terminal to which a channel indicated by the second subfield is allocated, and
transmit, by using the transceiver, a second non-data frame through the channel indicated by the second subfield of the channel field to the base wireless communication terminal when the first subfield of the channel field indicates an AID of the wireless communication terminal,
wherein the AID of the wireless communication terminal identifies an association between the wireless communication terminal and the base wireless communication terminal.
