Abstract: Radio link Failure (RLF) reporting operation in a wireless communication system using multiple cells is disclosed. According to this operation, when a first cell and a second cell are simultaneously connected to a UE and the first cell and the second cell are of different base stations (a first base station and a second base station respectively), if the RLF with the UE on the first cell is detected by the first base station, the first base station may transmits an indication of the RLF with the UE on the first cell to the second base station.

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.
