Abstract
A terminal station radio communication device belongs to a second radio communication system which shares a frequency channel with a first radio communication system in which a radio terminal station communicates with a radio base station in a predetermined time period using a predetermined frequency channel. The terminal station radio communication device includes: a transmission power determining unit which sets up signal transmission power, the signal transmission power being usable for communications between radio communication devices belonging to the second radio communication system, and being determined such that reception power at the radio base station is below a predetermined threshold; a synchronizer enabling the radio terminal station to obtain timing information to start signal transmission; and a signal transmitter starting transmitting the signal at the timing represented by the timing information and terminating the signal transmission within a predetermined time period.
