    • Systems and techniques for reducing or eliminating interference in licensed frequency bands. A device, such as a UE, upon recognizing that it is experiencing interference, transmits an inquiry using an unlicensed frequency band, such as a television white space (TVWS) band. A device that are potential sources of interference responds by transmitting a feedback signal providing information that can be used to identify it as an interferer. The device experiencing interference performs analysis to identify interferers, or simply transmits the feedback information to its base station. The base station, upon identification of one or more interferers, uses unlicensed frequencies, such as TVWS bands, to communicate with neighboring base stations to request reduction or elimination of interference. Neighboring base stations respond by taking actions that may include scheduling management or transmit power reduction to reduce interference by their served devices.
    • 用于减少或消除许可频段干扰的系统和技术。 诸如UE的设备在识别出其正在经历干扰时,使用诸如电视白色空间(TVWS)频带的未经许可的频带来发送查询。 作为潜在干扰源的装置通过发送提供可用于将其识别为干扰源的信息的反馈信号作出响应。 遇到干扰的设备进行分析以识别干扰源,或者简单地将反馈信息发送到其基站。 基站在识别一个或多个干扰源时,使用诸如TVWS频带之类的非许可频率与相邻基站进行通信,以请求减少或消除干扰。 相邻基站通过采取可能包括调度管理或发射功率降低的动作来响应,以减少其被服务设备的干扰。

    • It is provided a method, comprising initializing a counter to a counter initial value; checking, if an absolute value of a difference of a current value of the counter and the counter initial value is below a threshold, wherein the threshold is larger than 1; if the checking is positive: providing an in-device coexistence indication comprising an indication of an interference due to an in-device coexistence; changing the counter by 1 such that the difference of the current value of the counter and the initial counter value is increased by 1; supervising if a timer is running; if the timer is not running, resetting the timer to an initial value and then starting the timer; else, if the checking is not positive: prohibiting the providing of the in-device coexistence indication; supervising if the timer has run for the maximum time; and changing the counter such that the absolute value of the difference of the value of the counter and the counter initial value is decreased when the timer has run for the maximum time.
    • 提供了一种方法,包括将计数器初始化为计数器初始值; 检查所述计数器的当前值和所述计数器初始值的差的绝对值是否低于阈值,其中所述阈值大于1; 如果检查是肯定的:提供包括由于设备内共存引起的干扰的指示的设备内共存指示; 将计数器改变1使得计数器的当前值和初始计数器值的差增加1; 监督一个计时器是否运行; 如果定时器未运行,请将定时器重置为初始值,然后启动定时器; 否则,如果检查不正确:禁止提供设备内共存指示; 监督计时器是否运行最长时间; 并且当定时器运行最大时间时,改变计数器使得计数器的值和计数器初始值的差的绝对值减小。
