基于上行信道冲激响应的辅载波预测

Uplink Channel Impulse Response Based Secondary Carrier Prediction

Prayag Gowgi, Vijaya Yajnanarayana

摘要:

典型的切换问题需要UE、服务基站和目标基站之间的复杂信令序列。在许多切换问题中,将基于下行链路的测量从用户设备传送到服务基站,并且基于这些测量做出关于切换的决定。这些测量连同用户设备与服务基站之间的信令在计算上是昂贵的,并且可能潜在地耗尽用户设备电池。与此相结合,未来的网络密集地部署有多个频率层,使得当前的切换机制次优,需要可以提高能量效率的更新方法。在这项研究中,我们将调查一个ML为基础的方法对次载波预测频率间切换使用的上行链路参考信号。

英文摘要:

A typical handover problem requires sequence of complex signaling between a UE, the serving, and target base station. In many handover problems the down link based measurements are transferred from a user equipment to a serving base station and the decision on handover is made on these measurements. These measurements together with the signaling between the user equipment and the serving base station is computationally expensive and can potentially drain user equipment battery. Coupled with this, the future networks are densely deployed with multiple frequency layers, rendering current handover mechanisms sub-optimal, necessitating newer methods that can improve energy efficiency. In this study, we will investigate a ML based approach towards secondary carrier prediction for inter-frequency handover using the up-link reference signals.
