摘要：
The present invention relates to a terminal device adapted to perform Licensed Assisted Access, LAA, synchronization and cell discovery, and data reception and transmission on a licensed carrier and on an unlicensed carrier. The terminal device comprises a reception unit adapted to receive, on the licensed carrier, control information message. The control information message includes synchronization and discovery signal information indicating the position of a synchronization and discovery signal on the unlicensed carrier. The reception unit of the terminal device can receive, on the unlicensed carrier at the position indicated by the synchronization and discovery signal information, the synchronization and discovery signal. A timing unit adjusts the timing for transmission and reception of data according to the received synchronization and discovery signal.
