摘要： Methods and apparatus are provided to enable aperiodic sounding reference signaling including frequency hopping through the use of additional RRC configuration. The methods can require little or no additional L1 overhead to support narrowband frequency hopping for aperiodic sounding transmissions. In some embodiments, an approach is provided for extending an LTE periodic sounding reference signal methodology to include aperiodic sounding. One benefit of the proposed technique is that it enables each UE to perform aperiodic channel sounding in sounding subframes, using a frequency-hopping pattern, in which the sounding bandwidth of the UE can be narrowed appropriately to match its link capability. Additional benefits of the new approach include better resource utilization, lower signaling overhead, faster channel information update rates, and lower blocking probabilities.
摘要翻译：提供方法和装置以使得能够通过使用额外的RRC配置来进行非周期性的探测参考信号，包括跳频。这些方法可能需要很少的或没有额外的L1开销来支持非周期性发声传输的窄带跳频。在一些实施例中，提供了一种用于将LTE周期性探测参考信号方法扩展以包括非周期性探测的方法。所提出的技术的一个好处是使得每个UE能够使用跳频图案来执行在探测子帧中的非周期性信道探测，其中可以适当地缩小UE的探测带宽以匹配其链路能力。新方法的另外好处包括更好的资源利用率，较低的信令开销，更快的信道信息更新速率和更低的阻塞概率。
