一种信道状态信息报告方法、装置、接收方法和装置
本申请要求在2018年04月12日提交中国专利局、申请号为201810327468.X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申请中。
技术领域
本申请涉及通信传输技术领域,具体涉及一种信道状态信息报告方法、装置、接收方法和装置。
背景技术
超宽带宽的高频段(即毫米波通信),成为未来移动通信发展的重要方向,吸引了全球的学术界和产业界的目光。特别是,在当下日益拥塞的频谱资源和物理网大量接入时,毫米波的优势变得越来越有吸引力,在很多标准组织,例如IEEE(Institute of Electrical and Electronics Engineers,电气和电子工程师协会)、3GPP(3rd Generation Partnership Project,第三代合作伙伴计划)都开始展开相应的标准化工作。例如,在3GPP标准组,高频段通信凭借着其大带宽的显著优势将会成为5G New Radio Access Technology(New RAT,5G新的无线接入技术)的重要创新点。
然而,高频段通信也面临着链路衰减的挑战,具体而言,包括传播路径损失大、空气吸收(尤其是氧气)吸收更大、雨衰影响较重等。面对这些挑战,高频段通信系统可以利用高频段波长较短和易于天线集成等特点,通过多天线阵列和波束赋形方案来获取高天线增益和对抗信号传输损耗,进而以确保链路余量和提升通信鲁棒性。
在天线权重(也称为,预编码、波束)训练过程中,高频段发端发送训练导频,接端接收信道并执行信道估计。然后,高频段接收端需要向训练发端反馈信道状态信息,便于实现收发端从可选的收发端天线权重对中,找到可以用于多路数据传输所需要的多组收发端天线权重对,提升整体的频谱效率。
现有5G通信系统中,模拟波束相关的信道状态信息反馈和数字波束相关的信道状态信息的反馈是独立解耦进行的。但是,考虑模拟波束反馈仅基于接收信号强度而无法考虑自干扰和互干扰的情况,实际反馈的模拟波束难以保证在 和数字波束结合后获得一个全局最优的组合方案。现有技术中并没有给出支持多个基站(或TRP(Transmission point传输节点))和多个panel(面板)场景下的模拟域和数字域相关信道状态信息联合上报的解决方案。

具体实施方式
为使本申请的发明目的、技术方案和有益效果更加清楚明了,下面结合附图对本发明的实施例进行说明,需要说明的是,在不冲突的情况下,本申请中的实施例和实施例中的特征可以相互任意组合。
如图1所示,本发明实施例提供一种信道状态信息的报告方法,应用于UE(User Equipment用户设备)端,包括:
S101、接收基站端发送的参考信号;
S102、根据与所述参考信号关联的第一类报告配置信令,将信道状态信息报告给基站,其中,所报告的信道状态信息需要满足预定的或者是第一类报告配置信令的约束。
进一步的,基站端通过发送波束来承载参考信号,而UE端通过接收波束来接收参考信号。进一步的,所述的信道状态信息的反馈是用于实现(模拟)发送波束的选择(或者收发波束对的选择)以及数字发端预编码的联合确定。
其中,所述的参考信号至少包括如下之一:
1)信道状态信息参考信号(CSI-RS)
2)信道状态信息干扰测量信号(CSI-IM)
3)解调参考信号(DMRS)
4)下行解调参考信号(DL DMRS)
5)上行解调参考信号(UL DMRS)
6)信道探测参考信号(SRS)
7)相位追踪参考信号(PT-RS)
8)随机接入信道信号(RACH)
9)同步信号(SS)
10)同步信号块(SS block)
11)主同步信号(PSS)
12)副同步信号(SSS)
所述波束可以为一种资源(例如发送端空间滤波器,接收端空间滤波器,发送端预编码,接收端预编码、天线端口,天线权重矢量,天线权重矩阵等),波束序号可以被替换为资源索引(例如参考信号资源索引),因为波束可以与一些时频码资源进行传输上的绑定。波束也可以为一种传输(发送/接收)方式;所述的传输方式可以包括空分复用、频域/时域分集等。
此外,基站端可以对于两个参考信号进行准共址(Quasi co-location)配置,并告知UE端。所述的准共址涉及的参数至少包括,多普勒扩展,多普勒平移,时延拓展,平均时延,平均增益和空间参数;其中,空间参数,可以包括空间接收参数,例如到达角,接收波束的空间相关性,平均时延,时频信道响应的相关性(包括相位信息)。
图2为本发明实施例中面向混合预编码(混合模拟数字波束赋型)收发机结构示意图。发送端和接收端配置多天线阵列单元(即antenna panel)单元,而每个天线面板包含多个收发天线和多个射频链路(即TXRU)。每个射频链路与天线阵列单元的相互连接(不排斥部分连接场景),每个天线单元与TXRU拥有一个数字键控移相器。通过各个天线单元上的信号加载不同相移量的办法,高频段系统实现模拟端的波束赋形(Beamforming)。具体而言,在混合波束赋形收发机中,存在多条射频信号流。每条信号流通过数字键控移相器加载AWV(天线权重矢量,antenna weight vector),从多天线单元发送到高频段物理传播信道;在接收端,由多天线单元所接收到的射频信号流被加权合并成单一信号流,经过接收端射频解调,接收机最终获得多条接收信号流,并被数字基带采样和接收。因此,混合预编码(混合模拟数字波束赋型)收发机可以同时产生指向多个方向的射频波束。
同时,发送端和接收端可能有多个面板,为了更好的支持空分复用和减少 硬件实现复杂度。因此,每个面板下,有效波束的数目是和实际可以支持最大的发送beam的数目是不对称的,即每个时刻可以发送的beam数目,即TXRU数目,是远小于可选波束数目。
从基站端角度看,天线阵列单元可以产生Nmax个波束,但是在一个时刻,仅有N个波束可以产生,例如天线阵列单元可以产生16个波束,但是在一个时刻仅可以发送一个波束。但是,不同面板之间发送波束并没有受限,所以可以有kN个波束可以同时产生,其中k表示基站端panel的数目。从基站和UE端交互的角度看,信道状态信息的反馈,需要重复考虑是否目前发送的参考信号是否可以同时发送,例如,如果UE反馈了两个发送波束下联合的PMI/CQI信息,但是,如果两个发送波束却无法一起发送(例如来自相同的一个天线面板),那么这样的信道状态信息的反馈是无意义的。
图3为本发明实施例的参考信号发送和信道相关信息反馈示意图。参考信号发送端,发送参考信号资源配置和第一类报告配置信令到参考信号接收端,并将参考信号发送给参考信号接收端。其中,参考信号资源配置和报告配置信令,共同用于约束信道状态信息的上报。
进一步的,对于参考信号的而言,配置框架采用了多层的结构,如图4所示。报告配置(即Reporting setting,也称为Reporting config)与一个或者多个参考信号资源配置(即CSI Resource setting,或者多个参考信号资源配置)关联;而,每个参考信号资源配置(CSI resource setting)包括k个参考信号资源集合(CSI resource set);而,每个参考信号资源集合(CSI resource set)下包括了多个CSI-RS resource或者SS block,其中,每个参考信号资源下包括了若干个端口,或者端口组。通过这种多层结构,基站端可以将其的配置限制有效的制约在不同的层上。本发明实施例中,所述的参考信号包括N个参考信号资源配置,每个所述参考信号资源配置包括M个参考信号资源集合,每个所述参考信号资源集合包括K个参考信号资源,每个所述参考信号资源包括L个参考信号端口;其中,N,M,K,L是大于或者等于1的整数。
进一步的,信道状态信息包括第一类信道状态信息集合和第二类信道状态信息集合,其中,第一类信道状态信息集合,包括以下至少之一:参考信号资源索引(RS resource index),参考信号资源集合索引(RS resource set index),参考信号资源配置索引(RS resource setting index),报告配置索引(Report  configuration index),参考信号端口组索引(port group index),参考信号端口组集合索引(port group set index),秩指示信息(Rank indicator,RI),其中,第一类信道状态信息集合中元素,是wideband宽带参数,或者partial-band部分宽带参数(wideband宽带参数,是指对于这个反馈事件中,可以覆盖所有的相关的带宽;而partial-band部分宽带参数,是指对于整个反馈事件中,可以作用部分的带宽);第二类信道状态信息集合,包括以下至少之一:参考信号资源索引(RS resource index),参考信号端口组集合索引(port group set index),参考信号端口组索引(port group index),秩指示信息(Rank indicator,RI),预编码矩阵指示信息(Precoding matrix indicator,PMI),信道状态指示信息(Channel quality indicator,CQI),层指示信息(Layer indicator,LI),端口索引(port index),幅度系数,相位系数,参考信号接收功率。

在同一个参考信号资源配置下,仅有一个参考信号资源可以被报告,即U2=1,即参考信号资源的索引信息;
在不同参考信号资源配置下,即选择来自不同的参考信号资源配置,可以有不同的参考信号资源可以被报告。

按端口组序号,将所有的端口组分成F2个端口组集合;
其中,F1或者F2参数是通过第二通信节点,即基站端,配置。
实施例六
第一类信道状态信息,反馈了相应的TRP,panel和beam信息,而对于数字预编码的反馈需要通过第二类信道状态信息反馈。因此,需要明确,第一类信道状态信息集合中的子集与第二类信道状态信息集合中的子集的关联信息。
例如,第一类信道状态信息包括两个子集,每个子集包括一个CRI和一个resource set index,而第二类信道状态信息子集,例如两个PMI,需要分别与第一类信道状态信息的两个子集相对应。其中PMI是包含了各个layer上的预编码信息,但是CRI是需要映射到所有的预编码的。进一步的,CRI的反馈确定是基于所反馈的resource set index,而resource set index的反馈是基于所反馈的RS setting index。
进一步的,可以通过使用比特地图字段(或者称为比特字段,bitmap,或者bit string),指示第一类信道状态信息集合中的子集与第二类信道状态信息集合中的子集的关联信息,或者,
报告与第一类信道状态信息集合中子集所关联的层信息,或者,
报告与第二类信道状态信息集合中子集所关联的层信息。
进一步的,比特字段与第一类信道状态信息集合中的子集关联,而若比特位置为第一预定数值时,表示关联所述比特位置所关联的第二类信道状态信息集合中的子集;或者,
比特字段与第一类信道状态信息集合中的子集关联,并且与第二类信道状态信息集合中的子集关联,而所述比特字段的比特位置信息指示所关联的层信息;
或者,进一步的,比特地图字段与第二类信道状态信息集合中的子集关联,而若比特位置为第二预定数值时,表示关联所述比特位置所关联的第一类信道状态信息集合中的子集;
其中,所述比特字段中预定数值的数目或者预定数值的数目上限是由第二通信节点配置;
进一步的,每个第一类信道状态信息集合中的子集所关联的所述比特地图字段中特定数值的个数相同;或者,每个第二类信道状态信息集合中的子集所关联的所述比特地图字段中特定数值的个数相同;进一步的,第二类信道状态信息集合中的子集内部元素之间存在关联关系,并且与所述的比特地图中特定数值的元素依次映射。
其中,第一类信道状态信息的子集或者元素的可选数目决定所述子集或者元素的反馈比特数目。
进一步的,还包括如下至少之一:所述的关联信息,是层指示信息。
例如,考虑发送波束的限制,Nsimu_max CRI(s)可以被选择并且可以被应用到部分的层上。因此,对于么一个层上可以选择Nsimu_max+1个信息,其中第一个信息表上无CRI可以被用到该层上。
或者,例如,使用比特地图(bitmap)执行层指示的办法来进行CRI与PMI,幅度信息和相位系数的关联,如下表所示。需要说明的,如果层指示信息,也称为所关联的层信息,表示为1时,表示与该对应的层关联,而后选择对应的幅度指示信息、相位指示信息和端口指示信息,来读取,在该CRI下的端口和对应的幅度和相位预编码反馈。

Figure PCTCN2019082228-appb-000002
进一步的,在波束(L1-RSRP)报告情况下,RSRP为第二类信道状态信息),而参考信号资源集合索引和参考信号资源索引为第一类信道状态信息,如下表所示。
Figure PCTCN2019082228-appb-000003
因此,在本申请所涉及的多个基站(或TRP)和多个panel以及模拟域波束和数字域波束联合上报的问题,是通过第一类信道状态信息反馈,第二类信道状态信息反馈,以及第一类和第二类信道状态信息的关联信息,例如比特地图来实现。进一步的,多个基站(或TRP)和多个panel以及模拟域波束的信息是通过第一类信道状态信息反馈,而数字域相关信息是通过第二类信道状态信息反馈。最后,通过关联关系将两种信息相互关联进行联合上报,例如上表中的层指示信息。
实施例七
如图5所示,本发明实施例还提供了另一种参考信号配置另一示意图,其中报告配置与CSI resource setting相关联,其中CSI resource setting共包含了k个CSI resource set,其中每个CSI resource set中包含n个CSI resource,而每个CSI resource下包含m个端口组(port group),其中每个端口组中包含4个port。从基站的角度看,不同的端口(port)对应不同的数字波束(digital beam),不同的端口组(port group)对应不同的模拟波束(analog beam),而不同的CSI resource对应不同的panel或者subarray。此外,通过不同的CSI resource set来区分不同的TRP级别。
从信道状态信息报告的角度看,第一类信道状态信息集合是由“参考信号 资源索引,参考信号资源集合索引,参考信号端口组索引,秩指示信息”组成,而第二类信道状态信息是由“信道状态指示信息,幅度系数,相位系数”组成。
进一步的,从报告的准则来看,希望选择其中一个TRP,然后对于TRP下的多个panel中,每个panel下最多选择一个端口组合。进一步的,有如下报告约束:
从参考信号资源集合的角度,只报告相同的参考信号资源集合下的参考信号资源索引;不报告不同的参考信号资源集合下的参考信号资源索引;

层指示信息关联到所报告的端口组上,与第二类信道状态信息关联。
进一步的,信道状态信息报告如下表所示,其中,层指示信息和第一类信道状态信息是宽带信息,而第二类信道状态信息是子带信息。在RI=4的情况下,首先选择了一个参考信号资源集合,而在该参考信号集合下,在两个不同的resource下各选择了一个参考信号端口组。进一步的,使用层指示信息(比特地图)来是指所述的第一类信道状态信息子集-1,即{CRI-1,Port group-3},和第一类信道状态信息子集-2,即{CRI-2,Port group-1},与第二类信道状态信息的关联关系。

其中,需要说明的是,对于幅度系数和相位系数而言,需要为所对应的参考信号端口组下的各个端口和所对应的层下提供相关信息。例如,对于所选择的参考信号端口组为4个端口,而所关联的层是2层时(通过层指示信息中的非零元素个数确定),提供{P0,0,P0,1,P0,2,P0,3}—层0,{P1,0,P1,1,P1,2,P1,3}—层1,{A0,0,A0,1,A0,2,A0,3}—层0,{A1,0,A1,1,A1,2,A1,3}—层1。

从信道状态信息报告的角度看,第一类信道状态信息集合是由“参考信号资源索引,参考信号资源集合索引,参考信号端口组集合索引,参考信号端口组索引,秩指示信息”组成,而第二类信道状态信息是由“信道状态指示信息,幅度系数,相位系数”组成。
进一步的,从报告的准则来看,希望选择其中一个TRP,然后对于TRP下的多个panel中,每个panel下的波束细化组仅可以选择一个端口组合,但是不同的波束细化组可以选择不同的端口组合。进一步的,有如下报告约束:
从参考信号资源集合的角度,只报告相同的参考信号资源集合下的参考信号资源索引;不报告不同的参考信号资源集合下的参考信号资源索引;
从参考信号资源的角度,不同参考信号资源下,报告所述不同参考信号端口组集合索引;相同参考信号资源下,报告所述参考信号资源下的S1=2个参考信号端口组集合索引;

进一步的,信道状态信息报告如下表所示,其中,层指示信息和第一类信道状态信息是宽带信息,而第二类信道状态信息是子带信息。在RI=4的情况下,首先选择了一个参考信号资源集合,而在该参考信号集合下,在两个不同的resource下各选择了一个参考信号端口组集合。进一步的在每个端口组集合中选择一个参考信号端口组。进一步的,使用层指示信息(比特地图)来是指所述的第一类信道状态信息子集-1,即{CRI-1},和第一类信道状态信息子集-2,即{CRI-2},与第二类信道状态信息的关联关系。
