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 functionally connected with the communication module, the processor is configured to:
- receive, from a base station, data,
- transmit, to the base station, a HARQ-ACK related to the data,
- wherein the data is transmitted on a first component carrier in a carrier set,
- wherein the first component carrier is a component carrier in which back-off using a common back-off counter is completed,
- wherein the data is transmitted when the first component carrier is idle during a predetermined defer period by performing a CCA (Clear Channel Assessment) on the first component carrier during the defer period,
- wherein the common back-off counter is obtained based on a largest contention window value among contention window values of component carriers included in the carrier set,
- wherein the contention window values of each of the component carriers is independently configured,
- wherein the defer period is composed of at least one slot.
A data communication method using multiple carriers by a user equipment in a wireless communication system, the method comprising:
- receiving, from a base station, data;
- and
- transmitting, to the base station, a HARQ-ACK related to the data,
- wherein the data is transmitted on a first component carrier in a carrier set,
- wherein the first component carrier is a component carrier in which back-off using a common back-off counter is completed,
- wherein the data is transmitted when the first component carrier is idle during a predetermined defer period by performing a CCA (Clear Channel Assessment) on the first component carrier during the defer period,
- wherein the common back-off counter is obtained based on a largest contention window value among contention window values of component carriers included in the carrier set, and
- wherein the contention window values of each of the component carriers is independently configured,
- wherein the defer period is composed of at least one slot.
