Abstract: In the present invention, a user equipment (UE) receives a paging message associated with downlink (DL) data. The UE transmits a paging feedback using a uplink (UL) grant associated with the paging message. The UE monitors a physical downlink control channel (PDCCH) to receive the DL data.

Abstract: The present invention relates to uplink signal transmission by a user equipment (UE) in terms of timing advance value in a wireless communication system. According to an embodiment of the invention, the UE applies a predetermined timing advance value for a TAG (Timing Advance Group) if the TAG includes only one or more first type cells. Here, a random access procedure is not supported on the first type cells. Based on it, the UE transmits the uplink signals to the network on one of the first type cells based on the timing advance value applied for the TAG.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing DRX operation in wireless communication system, the method comprising: generating a MAC PDU including an indicator indicating the MAC PDU is a last MAC PDU to be transmitted to an eNB if the generated MAC PDU is a last MAC PDU to be transmitted to the eNB; transmitting the MAC PDU including the indicator; and starting using a DRX cycle right after the UE considers that the transmission of MAC PDU is successful.
