Abstract: Provided are a communication device and a communication method capable of further improving the quality between radio links in a communication system in which a base station device and the communication device communicate with each other. A communication device (50) according to the present disclosure includes a receiver (511a) and a transmitter (512d). The receiver (511a) receives a synchronization signal transmitted from a base station device (20, 30). The transmitter (512d) transmits a physical random access channel (PRACH) including a feature capable of uniquely identifying the synchronization signal received by a receiver (511a) and/or a PRACH resource to the base station device (20, 30).
