Abstract: A method of reporting integrity verification failure by a user equipment (UE) in a wireless communication system. The method includes: receiving a data unit from a network; performing integrity verification using the data unit; and when the integrity verification fails, reporting information about the integrity verification failure to the network. The information about the integrity verification failure includes: (i) a radio bearer identity associated with the integrity verification failure, and (ii) at least one Packet Data Convergence Protocol (PDCP) COUNT value associated with the radio bearer identity.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for allocating uplink resources in the wireless communication system, the method comprising: transmitting, by a first eNB to a second eNB, uplink (UL) resource allocation information for a user equipment (UE) connected with both the first eNB and the second eNB; receiving, by a first eNB from the UE, buffer size information; allocating one or more UL resources to the UE, by considering both of the buffer size information and the UL resource allocation information, wherein the UL resource allocation information indicates a ratio of the buffer size to be considered in each eNB.

Abstract: A user equipment (UE) starts a downlink (DL) discontinuous reception (DRX) retransmission timer for a DL hybrid automatic repeat and request (HARQ) process of the UE. The UE monitors a physical downlink control channel (PDCCH) while the DL DRX retransmission timer for the DL HARQ process is running The UE stops the DL DRX retransmission timer for the DL HARQ process when the UE receives a PDCCH indicating a uplink (UL) transmission.

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.
