Abstract

Description

通信方法及***
本公开要求在2017年12月08日提交中国专利局、申请号为201711299493.3的中国专利申请的优先权,该申请的全部内容通过引用结合在本公开中。
技术领域
本公开涉及通信技术领域,例如涉及一种通信方法及***。
背景技术
一般,在上行通信中,应该使用非预编码的参考信号,即:天线专有的参考信号,而对物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的用于解调的参考信号(De Modulation Reference Signal,DMRS)则进行预编码。演进型基站(e-Node-B,eNB)通过接收用户设备(User Equipment,UE)发送的非预编码的参考信号,可估计出上行的原始信道状态信息(Channel State Information,CSI),而经过了预编码的DMRS则不能使eNB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参考信号时,每个UE所需要的参考信号资源都会增加,也就造成了***内可以同时复用的UE数量下降。UE可通过高层信令(也称为通过触发方式(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参考信号,基于高层信令触发的为周期参考信号,基于下行控制信息触发的为非周期参考信号。非周期发送参考信号的方式,一定程度上改善了参考信号资源的利用率,提高资源调度的灵活性。
随着通信技术的发展,数据业务需求量不断增加,可用的低频载波已经非常稀缺,由此,基于还未充分利用的高频(30~300千兆赫兹(GHz))载波通信成为解决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。虽然高频载波通信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,但是由于高频信号的波长的减小,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,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,NR)中,高频通信***中,除了eNB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,UE同样也会配置大量的天线形成上行传输波束,此时参考信号的发送也将会采用波束的形式发送。另外,在NR***中,帧结构相比LTE/LTE-A***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,因此,LTE/LTE-A***中发送参考信号的方法不能应用于NR***,相关技术中还没有NR***中发送参考信号对应的通信方案。
发明内容
本公开实施例提供了一种通信方法及***,以至少提供一种NR***中发送参考信号的方式,实现了在NR***中有效地发送参考信号。
本公开提供了一种通信方法,应用于第一通信节点,包括:确定第二通信节点发送参考信号所使用的无线资源;接收所述第二通信节点使用所述无线资源发送的参考信号。
本公开还提供了一种通信方法,应用于第二通信节点,包括:确定发送参考信号所使用的无线资源;使用所述无线资源发送参考信号给第一通信节点。

附图说明

图2是另一实施例提供的一种通信方法的流程图;

具体实施方式
下文中将参考附图并结合实施例来说明本公开。
本公开的说明书和权利要求书及上述附图中的术语“第一”或“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。
在长期演进(Long Term Evolution,LTE)中,物理下行控制信道(Physical Downlink Control Channel,PDCCH)用于承载上行调度信息、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,DCI)格式(format)分为DCI format 0、1、1A、1B、1C、1D、2、2A、3以及3A等,在后面的演进中又增加了DCI format 2B、2C以及2D以支持多种不同的应用和传输模式。演进型基站(e-Node-B,eNB)可以通过下行控制信息配置UE,或者UE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,参考信号)是一种UE与eNB间用来测量无线CSI的信号。在长期演进***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参考信号。eNB根据接收到的参考信号判断UE上行的CSI,并根据得到的CSI进行频域选择调度以及闭环功率控制等操作。
LTE/LTE演进(LTE-Advanced,LTE-A)***中,当参考信号序列的长度小于72时,可用的参考信号根序列的数量为30;当参考信号序列的长度大于或等于72,且组跳转功能不使能时,可用的参考信号根序列的数量为60,当参考信号序列的长度大于或等于72,且组跳转功能使能时,可用的参考信号根序列的数量为30。
本公开实施例可以运行的网络架构包括:第一通信节点和第二通信节点,其中,第一通信节点和第二通信节点进行交互。
