ETSI TS 103 060提供了用作频率和应用程序的占空比模板（DCT）的定义 独立的被动缓解技术，以及相关的一致性测量方法。DCT由一个活动的传输间隔和一个非活动的空闲间隔组成。这两者的结合 为共享频谱提供缓解技术的基础。占空比（DC）是一种信号特性，即在激活状态下花费的时间占激活状态下总时间的一小部分 考虑DCT与DC的不同之处在于，它将传输的定义泛化为包括对定义的传输的操作 观测带宽和定义的观测时间，因为它们影响正在考虑和协调的系统 超宽带和非超宽带系统治疗。因此，DCT要求应定义对单个传输参数的限制，以避免 对受害系统接收器的有害干扰，即使它们同时在近距离和 在相同的无线电频谱中，同时使用相同的带宽。

ETSI TS 103 060 provides a definition of Duty Cycle Template (DCT) to be used as a frequency and application independent passive mitigation technique, and associated conformance measurement methods.DCT consists of an active transmission interval followed by an inactive idle interval. The combination of these two provides the basis of the mitigation technique to share spectrum.Duty Cycle (DC) is a signal property that is the time spent in an active state as a fraction of the total time under consideration. DCT differs from DC by generalizing the definition of a transmission to include operation over a defined observation bandwidth and defined observation time, as they affect the systems under consideration and harmonizing Ultra Wideband and non-Ultra Wideband systems treatment.As a result, the DCT requirement should define limits on individual transmission parameters in such a way as to avoid harmful interference to victim system receivers even if they are simultaneously operated in close physical proximity and in the same radio spectrum bandwidth at the same time.
