Abstract: A method and apparatus for delaying transmission or reception on an unlicensed cell in a wireless communication system is provided. A user equipment (UE) performs downlink (DL) reception or uplink (UL) transmission on a second cell. The second cell is a second serving cell on an unlicensed carrier. The UE receives a backoff time for the second cell from a first cell when there is overload in the unlicensed carrier. The first cell is a first serving cell on a licensed carrier. The UE suspends ongoing DL reception or UL transmission on the second cell during the backoff time.

Abstract: The invention relates to a method comprising classifying user equipment (UE) cells, to which carrier aggregation is applied, into a plurality of time advance groups. Uplink-time synchronization is managed using the time synchronization of a primary cell (Pcell) in the time synchronization group to which the primary cell belongs. For other time synchronization groups, the uplink time synchronization is managed using the time synchronization of a secondary cell (SCell) that is particularly set in the relevant time synchronization group. Thus, the plurality of time synchronizations can be effectively managed for the UE and a base station (BS).

Abstract: A method and apparatus for receiving system information in a wireless communication system is provided. A user equipment (UE) receives an indication indicating whether a cell supports a short transmission time interval (TTI) from the cell, and receives at least one of normal TTI system information in a normal TTI or short TTI system information in the short TTI from the cell according to the received indication. That is, an eNodeB (eNB) may schedule separate system information block type 1 (SIB1) and/or SI messages broadcast in short TTI.

Abstract: The present invention relates to MAC layer communication for parallel random access procedures of dual connectivity. In this scheme, a first MAC entity of a user equipment informs the initiation of the first random access procedure to a second MAC entity of the UE; and informs the completion of the first random access procedure to the second MAC entity, when the first random access procedure is finished.

Abstract: Provided are a method of measurement reporting and a device supporting the method. According to one embodiment of the present invention, the method includes: receiving a configuration of condition for measurement report; starting a first timer related to a first cell, when a report triggering event for the first cell is occurred; detecting a triggering event for a second cell and that the condition is satisfied; and reporting measurement results of the first cell and the second cell, when the first timer is expired or stopped.

Abstract: A method and apparatus for supporting a measurement reporting enhancement for an aerial device in a wireless communication system is provided. A prohibit timer can be used in order to prohibit frequent measurement reporting, and the prohibit timer may be stopped when a leaving condition for the measurement reporting is satisfied and/or a handover procedure and/or a radio resource control (RRC) connection re-establishment procedure is performed.
