Method for transmitting a power headroom reporting in a carrier aggregation with at least one SCell operating in an unlicensed spectrum and a device therefor
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting a power status reporting in a carrier aggregation with at least one SCell operating in an unlicensed spectrum, the method comprising: receiving, by a MAC entity, an uplink grant to transmit data on an unlicensed cell from an eNB; checking, by the MAC entity, whether the unlicensed cell is available for transmitting the data using the uplink grant; determining, by the MAC entity, not transmitting the data using the uplink grant if the unlicensed cell is not available for transmitting data; and triggering, by the MAC entity, a PHR when the UE determines that the data is not to be transmitted.
