A communication system includes a terminal configured to wirelessly communicate with a base station, a plurality of IoT terminals, and a control device. The control device includes a processor; and a memory that includes instructions, which when executed, cause the processor to execute the following steps: selecting an IoT terminal around a dead zone and transmitting a command of signal transmission to the selected IoT terminal. The selected IoT terminal includes a receiver configured to receive the command, and a transmitter configured to transmit a signal according to the command. The terminal receiving the signal transmitted from the selected IoT terminal performs a connection operation for avoiding the dead zone.

Communication system, connection designation control method, control apparatus and program

A specific signal in a radio communication system includes at least one of a synchronization signal and a reference signal. A first radio communication system performing radio communication in a first cell generates the specific signal based on a first seed and uses a first resource mapping pattern as a resource mapping pattern of the specific signal. A second radio communication system performing radio communication in a second cell that is adjacent to the first cell generates the specific signal based on a second seed and uses a second resource mapping pattern as a resource mapping pattern of the specific signal. When the first resource mapping pattern is identical to the second resource mapping pattern, the first seed and the second seed are set to be different from each other through sequence seed control.
