Abstract: A method and apparatus for configuring a cell in a wireless communication system is provided. A user equipment (UE) receives a radio resource control (RRC) message which includes a configuration for a secondary cell (SCell) and an indication of an initial state of the SCell. The initial state of the SCell is set to either one of an activated state and deactivated state. The UE configures the SCell based on the configuration and the initial state of the SCell.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for triggering a sidelink buffer status reporting in a D2D communication system, the method comprising: configuring a first ProSe destination including at least one first UE and a second ProSe destination including at least one second UE; receiving a first sidelink data for a first sidelink logical channel from an upper layer; receiving a second sidelink data for a second sidelink logical channel from the upper layer while the UE has the first sidelink data for the first logical channel, wherein the second logical channel has a higher priority than a priority of the first sidelink logical channel; and triggering a buffer status reporting the if the first sidelink logical channel and the second sidelink logical channel belong to a same ProSe destination.

Abstract: A method for transmitting data through a logical channel by a user equipment (UE) in a wireless communication system is disclosed. The method comprises determining whether data for the logical channel exists or not; increasing a token value based on a prioritized Bit Rate (PBR) and a time elapsed since the data becomes available for the logical channel, when the data for the logical channel exists; and transmitting the data or a part of the data through the logical channel, when the token value is greater than 0, wherein when there is no data for the logical channel, the token value is not increased.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to triggering conditions for power headroom reporting (PHR) in a wireless network employing TDD scheme. According to one aspect of the present invention, the a user equipment (UE), receives information on a first time division duplex (TDD) uplink/downlink (UL/DL) subframe configuration, and information on a second TDD UL/DL subframe configuration informing the UE of a change from the first TDD UL/DL subframe configuration. And, the UE triggers a power headroom reporting (PHR), when the information on the second TDD UL/DL subframe configuration is received.

Abstract: In the present invention, a user equipment (UE) receives an UL grant that can be used while the UE is not in RRC_CONNECTED state. If the UE receives a message indicating to leave RRC_CONNECTED state, the UE starts a time alignment timer (I-TAT) when the UE leaves RRC_CONNECTED state. The UE transmits UL data using the UL grant if the UL data becomes available for transmission when the UE is not in RRC_CONNECTED state and if the I-TAT is running.
