Abstract: A method and apparatus for a user equipment (UE) performing a random access to a network are disclosed. For this end, the UE selects a first carrier for the random access among multiple carriers, and transmits a first random access preamble for a first random access procedure via the first carrier to the network. Then, the UE applies backoff time to the first carrier and reselects a second carrier for the first random access procedure among the multiple carriers, when the first random access procedure is determined as not successful; and transmits a second random access preamble via the second carrier to the network. Here, reselecting the second carrier is performed before the backoff time applied to the first carrier ends.

Abstract: 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.
