1. A communication system comprising:
a receiving terminal;
a base station including a transmitter, which, in operation, transmits a system information broadcast; and
a transmitting terminal including:
a receiver, which, in operation, receives from the base station the system information broadcast; and
circuitry, which is coupled to the receiver and which, in operation,
if the system information broadcast includes information on an idle transmission radio resource pool, the information indicating radio resources usable by transmitting terminals in an idle state, performs a direct communication transmission to the receiving terminal over a direct link connection using the idle transmission radio resource pool; and
if the system information broadcast does not include the information on the idle transmission radio resource pool and includes information on a temporary transmission radio resource pool, the information on the temporary transmission radio resource pool indicating radio resources usable by transmitting terminals in an idle state or in a connected state, performs a direct communication transmission to the receiving terminal over a direct link connection using the temporary transmission radio resource pool.
