Abstract: In this disclosure, methods for antenna combining to meet the pilot requirement of the massive MIMO system, and apparatuses for the same are provided. In a user equipment (UE) perspective of view, the UE transmits first pilot signals via each of multiple antennas of the UE, and receives antenna combining information from a base station. Here, the antenna combining information combines the multiple antennas into one or more antenna groups based on the first pilot signals, and each of orthogonal sequences is allocated to each of the antenna groups. The UE transmits second pilot signals using the allocated orthogonal sequences for each of the antenna groups. The second pilot signals can be used for estimating downlink channel from the base station to the UE.

Abstract: The present invention relates to a method for transmitting information for synchronization of a user equipment by a base station in a wireless communication system and apparatus for the same. In one embodiment of the present invention, a source base station transmits a request message requesting uplink synchronization information according to a predetermined reference to a target base station, receives a response message including the synchronization information from the target base station in response to the requested message, and transmits the received synchronization information to one or more user equipments which are to move to a cell serviced by the target base station. The synchronization information is used when the user equipments move to the cell serviced by the target base station without a process of acquiring the synchronization information.
