    • Spectrum access for Internet of things (IOT) applications including receiving information about expected use by a primary user of a spectrum band in a radio frequency spectrum. The spectrum band is classified into at least two working modes based on the expected use. The spectrum band is sensed to determine a current access pattern of the primary user. Based on the classifying and the sensing, one of the working modes is selected as a current working mode of the primary user. Transmissions are scheduled on the spectrum band using a current schedule that is responsive to the current working mode of the primary user. If the current working mode of the primary user changes, the sensing, selecting, scheduling, and determining whether the current working mode has changed are re-performed. Otherwise, the transmission scheduling and determining if the current working mode has changed are re-performed.
    • 物联网(IOT)应用的频谱接入,包括接收关于无线电频谱中频谱带的主要用户预期使用的信息。 基于预期的使用频谱带分为至少两种工作模式。 感测频谱带以确定主用户的当前访问模式。 基于分类和感测,选择其中一种工作模式作为主用户的当前工作模式。 使用响应于主用户的当前工作模式的当前时间表在频谱带上调度传输。 如果主用户的当前工作模式改变,则重新执行感测,选择,调度和确定当前工作模式是否已改变。 否则,重新执行传输调度和确定当前工作模式是否改变。
