1. A communication apparatus comprising:
a receiver, which in operation, receives from a base station information of a first resource pool being indicated by a dedicated Radio Resource Control (RRC) signaling and information of a second resource pool being indicated by a System Information Block (SIB); and
a transmitter, which in operation, transmits a device to device (D2D) signal using the first resource pool or the second resource pool,
wherein the first resource pool is utilized among the first resource pool, the second resource pool and a preconfigured resource pool in a case that the first resource pool and the second resource pool are indicated in an RRC_CONNECTED state, and the second resource pool is utilized among the second resource pool and the preconfigured resource pool in a case that the second resource pool is indicated in an RRC IDLE state.
