Abstract: Embodiments are provided for using association rule mining to analyze performance counters of a mobile network, including converting a plurality of performance counters of a mobile network into a plurality of key performance indicators (KPIs), quantizing each KPI into one value of a set of values associated with that KPI, creating a set of items having multiple subsets corresponding to respective KPIs, where each item of a subset corresponds to a respective value of a particular set of values associated with a particular KPI, and generating association rules based, at least in part, on the set of items. In further embodiments, the quantizing the plurality of KPIs includes quantizing a first KPI into a first value of a set of three or more values associated with the first KPI.

Abstract: An LAA-LTE wireless device obtains data to be transmitted in subframes over a shared spectrum. The wireless device transmits a reservation message over the shared spectrum. The reservation message indicates that an initial synchronization message will be retransmitted a specified number of times at specified intervals, such as with a predetermined number of subframes between each retransmitted synchronization message. The wireless device transmits the initial synchronization message over the shared spectrum.

Abstract: A wireless device accesses a shared spectrum equitably in a self-organizing manner by determining success indices and adjusting courtesy parameters. The wireless device transmits wireless transmissions in a frame subframe structure over a shared spectrum, each of the subframes bounded by subframe boundaries at predetermined time intervals. The success index represents a measure of success in transmitting wireless transmissions in the shared spectrum. The wireless device performs a clear channel assessment to determine whether the shared spectrum is available at the end of the clear channel assessment time interval. The wireless device determines a gap interval between the end of the clear channel assessment time interval and the next subframe boundary and transmits the success index during the gap interval.

Abstract: A first wireless device determines the duration of a clear channel assessment interval based on feedback signals before transmitting data to a second wireless device. The first wireless device receives feedback signals, such as acknowledgement (ACK) and negative acknowledgement (NAK) signals, from one or more second wireless devices. The first wireless device determines a ratio of NAK/ACK signals in the feedback signals for a predetermined amount of time. The first wireless device determines whether the wireless medium is free by monitoring for wireless signals during a clear channel assessment interval. The duration of the clear channel assessment interval is based on the ratio of NAK/ACK signals. If the wireless medium is free for the duration of the clear channel assessment, the first wireless device wirelessly transmits data to at least one of the second wireless devices.

Abstract translation: 第一无线设备在将数据发送到第二无线设备之前基于反馈信号来确定清除信道评估间隔的持续时间。 第一无线设备从一个或多个第二无线设备接收诸如确认（ACK）和否定确认（NAK）信号的反馈信号。 第一无线设备确定反馈信号中的NAK / ACK信号的比例达预定的时间量。 第一无线设备通过在清除信道评估间隔期间监视无线信号来确定无线介质是否空闲。 清除信道评估间隔的持续时间基于NAK / ACK信号的比率。 如果无线介质在清除信道评估期间是空闲的，则第一无线设备向第二无线设备中的至少一个无线地发送数据。
