我们正在研究第五代新无线电（5G NR）中条件切换（CHO）的移动性性能、中断和信令开销。我们观察到，CHO将带来移动性鲁棒性和中断增益，但如果没有适当的参数化，可能会导致信令显着增加。此外，自组织网络（SON）优化CHO和CHO触发源质量的基础上，发现显着提高性能，而不增加信令。
We are studying the mobility performance, outage and the signaling overhead of conditional handover (CHO) in Fifth Generation New Radio (5G NR). We observe that CHO will bring mobility robustness and outage gain but could lead to significant increase in signaling if not properly parametrized. Also, self-organizing networks (SON) optimization for CHO and CHO triggering based on source quality are found to improve performance significantly without increased signaling.
