1. A second base station configured to provide Dual Connectivity in cooperation with a first base station, the second base station comprising:
circuitry comprising a transceiver and a processor, the circuitry being configured to:
transmit one or more beams comprising a synchronization signal, for a terminal device to perform a time synchronization with the second base station, wherein the one or more beams are included in a beam group, and wherein the synchronization signal comprises a time synchronization signal for the time synchronization and a broadcast signal for an initial access procedure,
send, to the terminal device via the first base station, synchronization information comprising:
timing information regarding the time synchronization, and
information regarding the beam group; and
receive, from the terminal device, information indicating a beam identifier of a beam determined based on a reception quality from among the transmitted one or more beams.
