Abstract
Disclosed are a method, an apparatus, and a system for transmitting a signal using multiple carriers. In detail, provided are a wireless communication apparatus including a communication module; and a processor, wherein the processor obtains a common back-off counter for a carrier set on which data is to be transmitted, wherein the carrier set includes at least one component carrier, performs back-off of each of the component carriers using the obtained common back-off counter, and simultaneously transmits data through at least one component carrier in which the back-off is completed and a wireless communication method using the same.
Claims18
A wireless communication apparatus, comprising:
- a communication module;
- and
- a processor,
- wherein the processor is configured to:
- obtain a common back-off counter for a carrier set on which data is to be transmitted, wherein the carrier set includes one or more component carriers,
- perform back-off for each of the component carriers using the obtained common back-off counter, and
- perform data transmission through at least one component carrier in which the back-off is completed,
- wherein the common back-off counter is determined based on a largest contention window value among contention window values of the one or more component carriers, and
- wherein the contention window values are set independently for each component carrier of the carrier set.
A data communication method using multiple carriers, the method comprising:
- obtaining a common back-off counter for a carrier set on which data is to be transmitted, wherein the carrier set includes one or more component carriers;
- performing back-off for each of the component carriers using the obtained common back-off counter;
- and
- performing data transmission through at least one component carrier in which the back-off is completed,
- wherein the common back-off counter is determined based on a largest contention window value among contention window values of the one or more component carriers, and
- wherein the contention window values are set independently for each component carrier of the carrier set.
