Base station, receiving device, mobile terminal and frequency sharing method |
摘要 |
A disclosed base station is used in a first wireless communication system using a first frequency band that is the same as or adjacent to a second frequency band used by a second wireless communication system, and includes a propagation loss estimation unit configured to estimate propagation loss of a signal in the first frequency band when the signal arrives at a receiving device of the second wireless communication system; a frequency difference calculation unit configured to calculate a frequency difference between the first frequency band and the second frequency band; a maximum transmission power determining unit configured to determine maximum transmission power based on the estimated propagation loss and the calculated frequency difference; and a transmission control unit configured to transmit a signal with transmission power less than or equal to the maximum transmission power determined by the maximum transmission power determining unit. |
