本申请基于申请号为201711148876.0、申请日为2017年11月17日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的内容在此以引入方式并入本申请。
技术领域
本发明涉及通信领域，具体而言，涉及一种通信方法及系统、存储介质和处理器。
背景技术
在相关技术中，在长期演进(Long Term Evolution，简称为LTE)中，物理下行控制信道(Physical Downlink Control Channel，简称为PDCCH)用于承载上、下行调度信息，以及上行功率控制信息。下行控制信息(Downlink Control Information，简称为DCI)格式(format)分为DCI format 0、1、1A、1B、1C、1D、2、2A、3、及3A等，后面演进至LTE-A Release 12(LTE-A版本12)中又增加了DCI format 2B、2C、2D以支持多种不同的应用和传输模式。第一通信节点(e-Node-B，简称为eNB)可以通过下行控制信息配置第二通信节点设备(User Equipment，简称为UE)，或者第二通信节点设备接受高层(higher layers)的配置，也称为通过高层信令来配置UE。
测量参考信号(Sounding Reference Signal，简称为SRS)是一种第二通信节点设备与第一通信节点间用来测量无线信道信息(Channel State Information，简称为CSI)的信号。在长期演进系统中，UE按照eNB指示的频带、频域位置、序列循环移位、周期和子帧偏置等参数，定时在发送 子帧的最后一个数据符号上发送上行SRS。eNB根据接收到的SRS判断UE上行的CSI，并根据得到的CSI进行频域选择调度、闭环功率控制等操作。
在LTE-A Release 10(LTE-A版本10)的研究中提出：在上行通信中，应该使用非预编码的SRS，即：天线专有的SRS，而对PUSCH的用于解调的参考信号(De Modulation Reference Signal，简称为DMRS)则进行预编码。第一通信节点通过接收非预编码的SRS，可估计出上行的原始CSI，而经过了预编码的DMRS则不能使第一通信节点估计出上行原始的CSI。此时，当UE使用多天线发送非预编码的SRS时，每个UE所需要的SRS资源都会增加，也就造成了系统内可以同时复用的UE数量下降。UE可通过高层信令(也称为通过trigger type 0触发)或下行控制信息(也称为通过trigger type 1触发)这两种触发方式发送SRS，基于高层信令触发的为周期SRS，基于下行控制信息触发的为非周期SRS。在LTE-A Release 10中增加了非周期发送SRS的方式，一定程度上改善了SRS资源的利用率，提高资源调度的灵活性。
LTE/LTE-A系统中，当SRS序列的长度小于72时，则可用的SRS根序列的数量为30；当SRS序列的长度大于或等于72，且组跳转功能不使能时，则可用的SRS根序列的数量为60，否则可用的SRS根序列的数量为30。
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与低频信号相比高频信号在空间的衰落非常大，高频信号的这种特性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。
在新的无线接入技术(New Radio Access Technology，简称NR)中，高频通信系统除了第一通信节点会配置大量的天线形成下行传输波束以补偿高频通信的空间衰落，第二通信节点同样也会配置大量的天线形成上行传输波束，此时SRS的发送也将会采用波束的形式发送。随着NR系统里面用户数的增多，SRS的容量需求会增大，因此有必要进一步增加SRS的根序列数量，特别是在SRS的序列组跳转使能的情况下。另外，在NR系统中，帧结构相比演进系统(LTE/LTE-A)系统的帧结构发生了很明显的变化，而且NR在时隙间跳频的基础上增加了时隙内的跳频，但相关技术中还没有对应的通信方案。
针对相关技术中存在的上述问题，目前尚未发现有效的解决方案。
