Abstract: A method and a user equipment (UE) are described for transmitting power headroom (PH) information. The UE generates PH information, and transmits the PH information to a base station. The PH information includes a first field including a plurality of indicators, each of the plurality of indicators indicating the presence of a second field indicating a PH level of a corresponding secondary cell (SCell). The PH information further includes a type-1 PH field and a type-2 PH field for a primary cell (PCell). Each of the plurality of indicators is set to 0 or 1. An indicator, which has been set to 1, indicates that the second field exists for the corresponding SCell, and an indicator, which has been set to 0, indicates that the second field does not exist for the corresponding SCell.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for calculating an amount of data available for transmission in the wireless communication system, the method comprising: receiving ratio for calculating amount of Data Available for Transmission (DAT) in a PDCP (Packet Data Convergence Protocol) entity; calculating an amount of DAT when data is arrived in the PDCP entity; and setting a first amount of DAT as the calculated amount of DAT and a second amount of DAT as ‘zero’, if the calculated amount of DAT is less than a threshold, wherein the first amount of DAT is for the first BS and the second amount of DAT is for the second BS.

Abstract: A method for receiving a multimedia broadcast multicast service (MBMS) by a user equipment (UE) in a wireless communication system; the UE therefore; a method for transmitting an MBMS by a base station (BS) in a wireless communication system; and the BS therefore are discussed. The method for receiving an MBMS by a UE according to one embodiment includes transmitting one or more system information blocks (SIBs); receiving a first MBMS interest indication message indicating whether MBMS reception is prioritized above unicast reception, when a predetermined SIB related to MBMS service continuity is included in the one or more SIBs; and receiving a second MBMS interest indication message according to a change of priority between the MBMS reception and the unicast reception.

Abstract: A method and apparatus for transmitting an indication in a wireless communication is provided. A user equipment (UE) transmits a multimedia broadcast/multicast service (MBMS) interest indication indicating a long-term evolution (LTE) frequency, and if an in-device coexistence (IDC) interference is detected on the LTE frequency, the UE transmits updated MBMS interest indication excluding the LTE frequency.
