    • Methods and apparatus of cell detection include determining whether communication between a user equipment and a serving cell satisfies a serving cell unsuitability condition (which may comprise a serving cell disconnection threshold value, i.e. a value indicative of potential or actual unsuitable wireless communication based on received signal code power (RSCP), reference signal received power (RSRP), reference signal received quality (RSRQ), signal-to-noise ratio (SNR), receive signal strength indicator (RSSI), or received energy-to-interference ratio). The methods and apparatus further include performing one or more autonomous search procedures (e.g. comprising searching for previously camped frequencies, searching a fingerprint database for fingerprinted cells or searching for available cells in all detected frequencies) based on whether the serving cell unsuitability condition has been satisfied. Moreover, the methods and apparatus include conducting cell reselection based on one or more results from the one or more autonomous search procedures, wherein the one or more results indicate at least one suitable cell for reselection.
    • 小区检测的方法和装置包括确定用户设备和服务小区之间的通信是否满足服务小区不适合性条件(其可以包括服务小区断开阈值,即,基于接收信号指示潜在或实际不合适的无线通信的值 参考信号接收功率(RSRP),参考信号接收质量(RSRQ),信噪比(SNR),接收信号强度指示符(RSSI)或接收的能量干扰比)。 所述方法和装置还包括执行一个或多个自主搜索过程(例如,包括搜索先前驻留的频率,在指纹数据库中搜索指纹的小区或在所有检测到的频率中搜索可用小区),基于是否满足了服务小区不适合性条件 。 此外,所述方法和装置包括基于来自一个或多个自主搜索过程的一个或多个结果进行小区重选,其中所述一个或多个结果指示用于重选的至少一个合适的小区。
