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

Claim 0:
1. A base wireless communication terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to:
transmit, by using the transceiver, a first non-data frame, wherein the first non-data frame reserves a Transmit Opportunity (TXOP), and allocates a first channel for a second non-data frame which is a response to the first non-data frame to each of a 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, wherein the AID identifies an association between a wireless communication terminal corresponding to the AID and the base wireless communication terminal, and
receive, by using the transceiver, at least one second non-data frame through the first channel from at least one of the first plurality of wireless communication terminals.
