Wireless communication system, transmission terminal, reception terminal, and transmission method |
摘要 |
The transmission terminal in a wireless communication system includes: a communication unit for intermittently transmitting a radio signal; a transmission-side beacon reception unit; a beacon analysis unit for analyzing the received beacon signal; and a transmission output level change unit for estimating an emission time period of a beacon signal to be received by the transmission-side beacon reception unit on the basis of the beacon period information and the beacon reception time information, thereby obtaining an estimated emission time period; wherein the transmission output level change unit instructs the transmission-side communication unit to transmit the radio signal having a raised transmission output level during at least the estimated emission time period, the raised transmission output level being higher than a transmission output level during a time period other than at least the estimated emission time period.
