Wireless communication method and wireless communication terminal using multiple channels
Provided is a wireless communication terminal. The wireless communication terminal includes a transceiver and a processor. The processor performs a contention procedure based on a back-off counter, in each of a plurality of channel and accesses, by using the transceiver, at least one of the plurality of channels based on the contention procedure.
1. A wireless communication terminal comprising:
a transceiver; and
a processor,
wherein the processor performs respective contention procedures in a plurality of channels, senses whether respective channels are idle or not for respective time intervals which are determined by respective back-off counters of the respective contention procedures, and performs transmission, by using the transceiver, in the plurality of channels based on the sensing.
2. The wireless communication terminal of claim 1 , wherein the processor, by using transceiver, transmits information indicating locations of the plurality of channels.
3. The wireless communication terminal of claim 1 , wherein the processor starts the respective contention procedures performed in the plurality of channels at the same time.
4. The wireless communication terminal of claim 3 , wherein the processor applies the same back-off counter to the respective contention procedures performed in the plurality of channels.
5. The wireless communication terminal of claim 1 , wherein the processor accesses a first channel of the plurality of channels based on a contention procedure in the first channel, regardless of a result of a contention procedure in another channel of the plurality of channels.
6. The wireless communication terminal of claim 1 , wherein the processor, by using transceiver, transmits information indicating the number of the plurality of channels.
7. The wireless communication terminal of claim 1 , wherein at least one channel of the plurality of channels are not contiguous to another channel of the plurality of channels.
8. An operating method of a wireless communication terminal, the method comprising:
performing respective contention procedures, in a plurality of channels;
sensing whether respective channels are idle or not for respective time intervals which are determined by respective back-off counters of the respective contention procedures; and
performing transmission in the plurality of channels based on the sensing.
9. The method of claim 8 , wherein the performing the contention procedure further comprises starting the respective contention procedures performed in the plurality of channels at the same time.
10. The method of claim 9 , wherein the performing the contention procedure further comprises applying the same back-off counter to the respective contention procedures performed in the plurality of channels.
11. The method of claim 8 , wherein the performing transmission comprises accessing a first channel of the plurality of channels based on a contention procedure in the first channel, regardless of a result of a contention procedure in another channel of the plurality of channels.
12. The method of claim 8 , wherein at least one channel of the plurality of channels are not contiguous to another channel of the plurality of channels.
