Provided is a host device (), which can establish a communication connection with a terminal device () and can be connected to a peripheral device (), including a first communication section and a second communication section, via the first communication section. The host device () transmits information for identifying the terminal device () acquired from the terminal device () to the peripheral device () as communication destination identification information that allows the peripheral device () to identify a communication partner in a case of performing communications via the second communication section, when the host device () is connected to the terminal device () and connected to the peripheral device () via the first communication section.

Communication system, host device, and terminal device

A communication terminal is provided with a transmission control unit for controlling a transmission mode in which a broadcast signal is transmitted a plurality of times, and a reception control unit for controlling a reception mode in which the broadcast signal transmitted from another communication terminal is monitored. The transmission control unit and the reception control unit execute the transmission mode and the reception mode cyclically and alternately. To achieve power saving, time reserved for execution of the transmission mode in a cycle is set to be longer than time reserved for execution of the reception mode in the cycle.
