    • Radio ports (RPs) in an unlicensed personal communications system adaptively, autonomously set their interference threshold and/or transmission power levels. This may be done by the RP measuring the signal level on each of the available channels and then setting the interference threshold and/or power level according to these measurements. In a preferred method (600), the interference threshold is determined by measuring the signal level on each channel (604), ranking the channels in order of measured signal level, and using these rankings to determined the threshold (606). The transmission power level may be set with reference to the adaptive interference threshold level. This level is determined by using the system and FCC power limitations and current conditions to provide a satisfactory transmission level.
    • 自动地设置无执照个人通信系统中的无线端口(RP),自主设置其干扰阈值和/或发送功率电平。 这可以通过RP测量每个可用信道上的信号电平,然后根据这些测量设置干扰阈值和/或功率电平来完成。 在优选方法(600)中,通过测量每个信道(604)上的信号电平来确定干扰阈值,按照测量信号电平的顺序对信道进行排序,并且使用这些等级来确定阈值(606)。 可以参考自适应干扰阈值电平来设置发射功率电平。 该级别由使用系统和FCC功率限制和当前条件确定,以提供令人满意的传输电平。
