Claim of US Patent No. 10,750,540

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), identifies a first plurality of wireless communication terminals, and allocates a first channel to each of the first plurality of wireless communication terminals using an index indicating predetermined channel usage pattern for a frequency band range,
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,
simultaneously transmit, by using the transceiver, a first plurality of data frames to a second plurality of wireless communication terminals, and
simultaneously receive, by using the transceiver, a second plurality of data frames from a third plurality of wireless communication terminals, through a second plurality of channels which are allocated to each of the third plurality of wireless communication terminals,
wherein the first plurality of data frames and the second plurality of data frames are transmitted in the TXOP.
