Description

参考信号的发送方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种参考信号(Reference Signal，简称为RS)的发送方法及装置。
背景技术
随着通信技术的发展，数据业务需求量不断增加，可用的低频载波也已经非常稀缺，由此，基于还未充分利用的高频(30～300GHz)载波通信成为解决未来高速数据通信的重要通信手段之一。高频载波通信的可用带宽很大，可以提供有效的高速数据通信。但是，高频载波通信面临的一个很大的技术挑战就是：相对低频信号，高频信号在空间的衰落非常大，虽然会导致高频信号在室外的通信出现了空间的衰落损耗问题，但是由于其波长的减小，通常可以使用更多的天线，从而可以基于波束进行通信以补偿在空间的衰落损耗。
但是，当天线数增多时，由于此时需要每个天线都有一套射频链路，基于数字波束成型也带来了增加成本和功率损耗的问题。因此，目前的研究中比较倾向于混合波束赋形，即射频波束和数字波束共同形成最终的波束。
高频通信中，除了要经历信道衰落以外，还要受到射频器件非线性因素的影响，使得接收端系统性能降低。相位噪声主要产生于收发两端的本地振荡器和锁相环，相位噪声作为一种乘性噪声会带来振荡器输出的频谱拓展，从而导致系统性能下降，尤其是在高频通信中，其影响更为突出。在现有相关技术研究中，一般会通过在数据信道插入导频来跟踪相噪的变化，接收端接收导频信号并处理和弥补相位噪声所带来影响。但如何在时频资源上合理地放置参考信号以及进行相应的信令触发，目前尚未存在有效的解决方案。
