摘要： Techniques for improved low latency frequency switching are disclosed. In one embodiment, a controller receives a frequency switch command and generates a frequency switch signal at a time determined in accordance with a system timer. In another embodiment, gain calibration is initiated subsequent to the frequency switch signal delayed by the expected frequency synthesizer settling time. In yet another embodiment, DC cancellation control and gain control are iterated to perform gain calibration, with signaling to control the iterations without need for processor intervention. Various other embodiments are also presented. Aspects of the embodiments disclosed may yield the benefit of reducing latency during frequency switching, allowing for increased measurements at alternate frequencies, reduced time spent on alternate frequencies, and the capacity and throughput improvements that follow from minimization of disruption of an active communication session and improved neighbor selection.
摘要翻译：公开了用于改进的低延迟频率切换的技术。在一个实施例中，控制器接收频率切换命令，并在根据系统定时器确定的时间产生频率切换信号。在另一个实施例中，在频率切换信号延迟预期频率合成器建立时间之后启动增益校准。在另一个实施例中，迭代DC取消控制和增益控制以执行增益校准，具有控制迭代的信令，而不需要处理器干预。还提出了各种其它实施例。所公开的实施例的方面可以产生在频率切换期间减少等待时间的优点，允许在替代频率下的增加的测量，减少在替代频率上花费的时间，以及从最小化主动通信会话的中断并改进的容量和吞吐量改进邻居选择。
