    • PROBLEM TO BE SOLVED: To maximize the communication capacity of a non-priority system while suppressing interference on a priority system by inter-subcarrier interference caused by the non-priority system at or below a permitted level in the case where the priority system and the non-priority system, which are not synchronized with each other, share a frequency.SOLUTION: A radio communication device communicating by use of a plurality of frequency elements in a second communication system sharing a frequency with a first communication system includes: a transmission power control unit which determines transmission power of each of the frequency elements so that interference power on a second frequency element (s) will be less than a permitted interference power level using at least a leakage power ratio (R) between transmission power (P) of a first frequency element (x) in the second communication system and power (P) generated on the second frequency element (s) in the first communication system; and means for generating and transmitting a transmission signal by converting a signal of a frequency domain in which the transmission power is determined into a signal of a time domain.
    • 要解决的问题:为了最大化非优先系统的通信能力,同时在优先系统和优先级系统的情况下,通过由非优先系统等于或低于允许级别引起的副载波干扰抑制对优先系统的干扰 非优先级系统彼此不同步,共享频率。解决方案:在与第一通信系统共享频率的第二通信系统中通过使用多个频率元素进行通信的无线电通信设备包括:发送功率 控制单元,其确定每个频率元件的发射功率,使得第二频率元件上的干扰功率将小于允许的干扰功率电平,所述干扰功率电平使用至少一个的发射功率(P) 第二通信系统中的第一频率元素(x)和在第一通信系统中的第二频率元件上产生的功率(P) 系统; 以及用于通过将确定发送功率的频域的信号转换为时域的信号来生成和发送发送信号的装置。
