Abstract
Provided is a wireless communication terminal including a transceiver for transmitting/receiving a wireless signal and a processor for controlling an operation of the wireless communication terminal. The transceiver receives a first frame indicating information on a resource that a base wireless communication terminal allocates to a plurality of wireless communication terminals from the base wireless communication terminal, and transmits data to the base wireless communication terminal based on the first frame. The plurality of wireless communication terminals include the wireless communication terminal.
Claims21
1-20. (canceled)
A wireless communication terminal comprising:
- a transceiver;
- and
- a processor,
- wherein the processor is configured to receive, by using the transceiver, a frame from a base wireless communication terminal,
- perform a CCA(clear channel assessment) in at least one of channels in response to receiving the frame, and
- transmit, to the base wireless communication terminal, a response frame for the frame based on the CCA, when a predetermined time elapses after receiving the frame.
A base wireless communication terminal comprising:
- a transceiver;
- and
- a processor,
- wherein the processor is configured to transmit, by using the transceiver, a frame to a plurality of wireless communication terminals, and
- receive at least one response frame for the frame from a plurality of wireless communication terminals, when a predetermined time elapses after transmitting the frame,
- wherein the at least one response frame is transmitted based on a CCA(clear channel assessment) which is performed by each of the plurality of wireless communication terminals.
An operating method of a wireless communication terminal comprising:
- receiving a frame from a base wireless communication terminal,
- performing a CCA(clear channel assessment) in at least one of channels in response to receiving the frame, and
- transmitting, to the base wireless communication terminal, a response frame for the frame based on the CCA, when a predetermined time elapses after receiving the frame.
