    • A method, system and device are provided for avoiding in-device coexistence interference between different radio technologies deployed in adjacent bands on the same device by controlling and separating the LTE signaling and the non-LTE signaling using dedicated time intervals to separate LTE signaling from non-LTE signaling. In addition, coexistence mode handover procedures are provided which use threshold-based triggering events to avoid coexistence interference and to prevent ping-pong effects by establishing a "keeping time" parameter so that a non-interfering network node does not switch back to an interfering network node after handoff. Coexistence interference is also avoided by providing a hybrid automatic repeat request (HARQ) mechanism which accounts for coexistence interference by providing a fixed or variable on-interval parameter and an activity parameter indicating whether non-LTE activity is present to maximize a time interval for non-LTE devices without interference from LTE activity on the same device.
    • 提供了一种方法,系统和设备,用于通过使用专用时间间隔控制和分离LTE信令和非LTE信令来避免部署在同一设备上的相邻频带中的不同无线电技术之间的设备内共存干扰,以将LTE信令与非信号分离 -LTE信号。 另外,提供了共存模式切换过程,其使用基于阈值的触发事件来避免共存干扰并且通过建立“保持时间”参数来防止乒乓效应,使得非干扰网络节点不切换回干扰 切换后的网络节点。 通过提供混合自动重复请求(HARQ)机制来避免共存干扰,该混合自动重复请求(HARQ)机制通过提供固定或可变的间隔时间参数来考虑共存干扰,以及指示是否存在非LTE活动以最大化非 - -LTE设备,不受同一设备上LTE活动的干扰。
