Description

一种信道状态信息的测量与反馈方法、用户设备及基站 技术领域
本发明涉及通信领域,具体涉及一种信道状态信息的测量与反馈方法。
背景技术
多天线(Multiple-Input Multiple-Output,MIMO)技术已经被广泛地应用在无线通信系统中来提高系统容量和保证小区的覆盖,如长期演进系统(Long Term Evolution,LTE)的下行采用了基于多天线的发送分集,开环/闭环的空分复用和基于DM-RS的多流传输,其中基于解调参考信号(Demodulation Reference Signal,DM-RS)的多流传输是LTE-A系统以及后续系统的主要传输模式。基于DM-RS的多流传输的流程是:UE首先根据演进型基站(evolved Node B,eNB)配置的信道状态指示参考信号(Channel Status Indicator Reference Signal,CSI-RS)进行信道测量,测量结果包括传输秩(Rank Indication,RI),传输秩所对应的预编码矩阵以及所述传输秩和预编码矩阵对应的信道质量指示(Channel Quality Indication,CQI);然后UE把测量结果反馈给eNB;eNB再根据UE反馈的测量结果进行下行调度,并根据调度结果把物理下行共享信道(Physical Downlink Shared Channel,PDSCH)通过DM-RS发送给UE。目前,基于DM-RS的多流传输都是二维的波束赋形,即发送天线都是水平放置,只能产生水平方向的波束。
为了进一步提高多天线系统的性能,LTE Rel-12标准中正在研究二维的天线配置,即天线同时放在水平和垂直方向上,从而可以同时进行水平和垂直方向上的波束赋形,被称为三维波束赋形。这样,相对于目前的二维波束赋形,增加了一个垂直方向上的自由度,那么在同样的时频资源上可以复用更多的用户,不同的用户通过垂直或水平方向上的波束来区分,提高资源的利用率或谱效率。
针对这种3D MIMO,现有技术中用户设备(User Equipment,UE)在物理上行控制信道(Physical Uplink Control Channel,PUCCH)上反馈CQI或是信道质量指示(Channel Quality Indicator,CQI)和预编码矩阵指示(Precoding  Matrix Indicator,PMI),具体的反馈模式为PUCCH X1-X2,其中X1值为1时,反馈的CQI为带宽CQI,X1值为2时,反馈的CQI为子带CQI;X2值为0时,不反馈PMI,X2值为1时,反馈PMI,PMI指示预设的码本中的预编码矩阵。
然而,对于LTE的Rel-13的基于波速赋型Beamformed CSI-RS机制,Rel-13即Release-13,现有技术的反馈模式中并没有考虑对新增波束选择指示(Beamforming Indication,BI)的上报,因此现有的PUCCH反馈模式无法应用于Rel-13的Beamformed CSI-RS机制中,另外,对于Rel-13的基于不带预编码的Non-precoded CSI-RS机制,由于天线配置变为二维的,会采用新的2D码本。现有的反馈模式无法应用,从而需要适用于最新2D码本的新的PUCCH的反馈方式。
发明内容
本发明实施例提供了一种信道状态信息的测量与反馈方法,一方面能够提供新的PUCCH反馈模式来适应Rel-13的Beamformed CSI-RS机制,还能够提供新的PUCCH反馈模式来适应Rel-13的Non-precoded CSI-RS机制,另一方面两种机制在设计时尽可能复用,从而减少两种不同机制下反馈类型和反馈模式的设计复杂度。
有鉴于此,本发明实施例第一方面提供信道状态信息的测量与反馈方法,可包括:
用户设备UE接收基站配置的第一信道状态信息报告类型以及基站下发的K个CSI-RS资源,K为大于等于1的整数;
UE根据信道状态信息报告类型在传输K个CSI-RS资源的宽带的S个子带上确定出一个RI和/或一个BI,S为大于等于1的整数;
UE在S个子带上计算得到CQI;
UE在物理上行控制信道PUCCH上通过报告上报RI、BI和CQI。
需要说明的是,该第一信道状态信息报告类型对应Beamformed CSI-RS机制。
可以理解的是,UE在接收基站下发的K个CSI-RS资源以及由基站配置的第一信道状态信息报告类型后,会确定上报的机制采用Beamformed  CSI-RS,而后UE会在传输K个CSI-RS资源的带宽的S个子带上确定出一个RI和/或一个BI,之后会在S个子带上计算出CQI,针对上报时刻的不同,会上报不同的内容,如单独上报RI,单独上报BI或是联合上报RI和BI,而后还会上报CQI,具体的上报可根据PUCCH反馈模式来确定,由于在PUCCH反馈模式中重新设计了反馈方式,使得BI也能够顺利上报。
结合第一方面,在第一方面的第一种可能的实现方式中,BI的上报周期大于等于RI的上报周期,报告的格式包括格式一、格式二和格式三,格式一的报告为BI的单独上报,格式二的报告为RI的上报,格式三的报告为BI和RI的联合上报,格式一的报告或格式三的报告的上报周期均为格式二的报告的上报周期的整数倍。
可以理解的是,BI的上报周期是大于RI的上报周期的,即相同时间段内,RI的上报次数大于等于BI的上报次数的,此外,报告的格式可包括三种,分别为格式一、格式二和格式三,格式一的报告为BI的单独上报,格式二的报告为RI的上报,格式三的报告为BI和RI的联合上报,能够针对不同的PUCCH反馈模式按照不同的格式或者格式组合进行上报。
结合第一方面的第一种可能的实现方式,在第一方面的第二种可能的实现方式中,PUCCH反馈模式为PUCCH 1-1或PUCCH 2-1,PUCCH 1-1或PUCCH 2-1中均分别包含反馈子模式一和反馈子模式二,反馈子模式一和反馈子模式采用不同的格式的报告的上报BI,反馈子模式一中采用格式一或格式三的报告的上报BI,反馈子模式二中采用格式三或格式一的报告的上报BI。
可以理解的是,在PUCCH 1-1或者PUCCH 2-1的反馈模式中,对于这两种反馈模式来说,每种反馈模式均可包括两种不同的反馈子模式,即子反馈子模式一和反馈子模式二,其中反馈反馈子模式一中采用格式一或格式三的报告的上报BI,反馈子模式二采用述格式三或格式一的报告的上报BI,可以灵活的配置报告的上报格式,从而增加本发明实施例方案的可扩展性。
结合第一方面的一种可能的实现方式,在第一方面的第三种可能的实现方式中,PUCCH反馈模式为PUCCH 1-1或PUCCH 2-1,PUCCH 1-1或PUCCH 2-1中均分别包含格式二的报告的上报和格式三的报告的上报,且格式三的报告的上报周期为格式二的报告的上报周期的整数倍。
可以理解的是,在PUCCH 1-1或PUCCH 2-1的反馈模式中,均包含格式二的报告的上报和格式三的报告的上报,即都包含RI的上报,以及RI和BI的联合上报,从而本发明实施例方案的可实现性。
结合第一方面的第一种可能的实现方式,在第一方面的第四种可能的实现方式中,PUCCH反馈模式为PUCCH 1-1或PUCCH 2-1,格式二的报告还包括PMI,PMI指示预设的码本中的预编码矩阵,包含PMI的格式二的报告为RI和PMI联合上报。
可以理解的是,PUCCH反馈模式为PUCCH 1-1或PUCCH 2-1时,格式二的报告中还可添加PMI,并且PMI的上报为与RI联合上报,从而本发明实施例方案的可实现性。
结合第一方面的第四种可能的实现方式,在第一方面的第五种可能的实现方式中,方法还包括:
BI的上报周期为RI的上报周期的M倍,不同天线端口数下有不同的M配置,M为大于等于1的整数。
可以理解的是,在格式二的报告为RI和PMI的联合上报的情形下,BI的上报周期为RI的上报周期的M倍。
结合第一方面的第一种可能的实现方式,在第一方面的第六种可能的实现方式中,UE在传输K个CSI-RS资源的宽带的S个子带上确定出一个预编码类型指示(Precoder type indicator,PTI),PTI指示预编码的类型;
格式一的报告还包括PMI或PTI,包含PMI的格式一的报告为BI联合PMI上报,包含PTI的格式一的报告为BI与PTI联合上报;格式三的报告还包括PTI,包含PTI的格式三的报告为BI,RI与PTI联合上报。
可以理解的是,UE在确定RI和BI时,还会确定出PTI,而PMI一般在基站配置给UE信道状态信息报告类型时,UE就可以确定出PMI了,PMI或者PTI均可被包含在格式一或者格式三的报告中,从而通过灵活的上报配置提高本发明实施例方案的可实现性。
结合第一方面的第六种可能的实现方式,在第一方面的第七种可能的实现方式中,PUCCH的上报格式包括格式3a、格式6a和格式7,根据CSI-RS资源的数量和空间复用的层数之中的至少一个确定报告的反馈比特数。
可以理解是,PUCCH的上报格式可以包括格式3a、格式6a和格式7,在这些格式中,具体的报告的反馈比特数由CSI-RS资源的数量和空间复用的层数之中的至少一个确定。
结合第一方面的第七种可能的实现方式,在第一方面的第八种可能的实现方式中,包含PMI的格式一的报告中的PMI为双码本结构中的第一预编码i1或单码本结构中的预编码i,方法还包括:
对预编码i或第一预编码i1下采样;
包含PMI的格式一的报告为BI和预编码i或第一预编码i1的联合上报。
可以理解是,PMI可以是双码本结构中的第一预编码i1或者是单码本结构中的预编码i,对预编码i或第一预编码i1下采样,下采样即对于一个样值序列间隔几个样值取样一次,得到新序列就是原序列的下采样,此处的样值为i或者i1均可进行下采样处理,而后可被包含在包含PMI的格式一的报告中,即将BI和i进行联合上报,或者将BI和i1进行联合上报。

本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”“第四”等(如果存在)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。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或模块的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或模块,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或模块。
本发明实施例应用于无线通信系统,例如LTE系统,WCDMA系统等,以LTE系统为例,请参阅图1,图1是LTE系统的结构示意图,包括基站101和用户设备102,其中基站对用户设备传输为下行传输,用户设备对基站为上行传输,一个基站可同时与多个用户设备进行通信。
在这些无线通信系统中可采用多天线MIMO技术,举例来说,请参阅图2,图2是现有技术中基于DM-RS的多流传输的通信系统的示意图,包括eNB201与多个UE202,其中,传输的都是二维的波束赋形,即发送天线都是水平放置,只能产生水平方向的波束,为了进一步提高多天线系统的性能,将天线同时放在水平和垂直方向上,从而可以同时进行水平和垂直方向上的波束赋形,被称为三维波束赋形,即3D MIMO的通信系统。
3D MIMO有不同的应用场景,如3D UMi场景,此场景下基站高度10米, 而用户可分布在1到8层的高楼内,因此用户在垂直向的分布相对较为分散,从而需要更多的垂直向基本向量。而另一种典型应用场景3D UMa下,基站高度为25米,用户同样分布在1到8层的高楼内但用户全部分布于基站的下面,因此此场景对垂直基本向量的需求相对UMi场景要小。一般2D情形下,2D天线配置下的码本结构主要由下面的直积形式组成:
Figure PCTCN2015094036-appb-000001
其中,X1和X2分别代表了某个极化方向下的水平矩阵或垂直矩阵,典型的其可以为DFT形式的向量或矩阵。而X′1和X′2为另一个极化方向下的水平矩阵或垂直矩阵。
Figure PCTCN2015094036-appb-000002
代表了克罗内克积或直积。W2定义同当前标准双码本结构中的W2,用于对W1进行列选择和两个极化方向间的同相操作。而W1的构成部分有上述水平矩阵(向量)和垂直矩阵(向量),2D码本结构中W1码本的候选基本矩阵(向量)个数P由基本水平矩阵(向量)个数M和基本垂直矩阵(向量)个数N联合决定。其中,P=M*N。
不论是Rel-13的Beamformed CSI-RS机制还是Non-precoded CSI-RS机制中,UE的PUCCH反馈模式均包含反馈模式为PUCCH X1-X2,其中X1值为1时,反馈的CQI为带宽CQI,X1值为2时,反馈的CQI为子带CQI;X2值为0时,不反馈PMI,X2值为1时,反馈PMI,PMI指示预设的码本中的预编码矩阵。具体反馈模式如下表所示:
表1
Figure PCTCN2015094036-appb-000003
具体的,现有技术中PUCCH 1-0的反馈模式中,RI和CQI按照如下方式进行上报:
1、在RI的上报时刻(仅适用于传输模式3):
UE在固定的S个子带上确定一个RI值;UE上报一个类型3的报告,此类型3的报告由一个RI组成。
2、在CQI的上报时刻:
UE上报一个类型4的报告,此类型4的报告由一个宽带CQI值组成,宽带CQI值为在固定S个子带上计算得到的值;其代表了RI=1或RI>1时第一个码字的信道质量。
其中,对于传输模式3来说,CQI基于最近上报的周期RI进行计算。对于其他传输模式,CQI基于秩1进行计算。
需要说明的是,现有技术中PUCCH 1-1反馈方式与上述类似,PMI可在RI的上报时刻或是CQI的上报时刻进行上报,此处不再赘述。
现有技术中PUCCH 2-0的反馈模式中,RI和CQI按照如下方式进行上报:
1、在RI的上报时刻(仅适用于传输模式3):
UE在固定的S个子带上确定一个RI值;之后UE上报一个类型3的报告,此类型3的报告由一个RI组成。
2、在宽带CQI的上报时刻:
UE在每个上报时刻上报一个类型4的报告,此类型4的报告由一个宽带CQI值组成,宽带CQI值为在固定S个子带上计算得到的值;其代表了RI=1或RI>1时第一个码字的信道质量。
其中,对于传输模式3来说,CQI基于最近上报的周期RI进行计算。对于其他传输模式,CQI基于秩1进行计算。
3、在UE选择子带上的CQI上报时刻:
UE在J个BP中的每个BP的个子带的集合中选择偏爱的子带。
UE上报类型1的报告,此类型1的报告由一个CQI值组成,CQI值仅反映了在一个BP的选择子带上的信道传输,伴随着偏爱子带的L-bit标示。每BP的类型1报告在接下来的上报时刻被轮流上报。其代表了RI=1或RI>1时第一个码字的信道质量。
需要说明的是,现有技术中PUCCH 2-1反馈方式与上述类似,PMI可在RI的上报时刻或是宽带CQI的上报时刻或是子带CQI的上报时刻进行上报, 此处不再赘述。
可以看出,对于Rel-13的基于波速赋型Beamformed CSI-RS机制来说,上述反馈模式中并未涉及BI的反馈布局,因此无法应用于该机制下;对于Rel-13的基于不带预编码Non-precoded CSI-RS机制下,由于采用的2D新码本,在反馈时需要考虑该码本的PMI11、PMI12和PMI2反馈布局,其中PMI11和PMI12是该码本的PMI1的一个维度的PMI。
实施例1
针对Beamformed CSI-RS机制,本发明实施例提供了一种信道状态信息的测量与反馈方法,请参阅图3,图3是本发明实施例的测量与反馈方法的一个实施例图,其中,该方法可包括:
101、UE接收基站配置的第一信道状态信息报告类型以及基站下发的K个CSI-RS资源。
其中,K为大于等于1的整数。
需要说明的是,第一信道状态信息报告类型在本发明实施例中为Beamformed CSI-RS机制下UE反馈的信道状态信息的类型,即信道状态信息类型报告B,即CSI report class B。
可以理解是,UE首先会根据基站配置的第一信道状态信息报告类型获知需要进行的道状态信息的反馈类型,此处为按照Beamformed CSI-RS机制进行反馈,在此机制下,UE会接收到基站下发的K个CSI-RS资源,以使得UE能够从根据CSI-RS资源上报一个最优的波束,即确定出一个最优的BI。
102、UE根据信道状态信息报告类型在传输K个CSI-RS资源的宽带的S个子带上确定出一个RI和/或一个BI。
其中,S为大于等于1的整数;
需要说明的是,UE可根据K个CSI-RS资源在一个上报时刻之前确定出三种类型的指示信息,一种是RI、一种是BI、一种是RI和BI,具体可根据后续上报时刻需要上报的是RI或BI或RI和BI的不同而不同。
103、UE在S个子带上计算得到CQI;
可以理解的是,在确定出一个RI和/或一个BI之后,UE会在S个子带上 计算得到CQI,该CQI的值反应了所选择信道的质量。
104、UE在PUCCH上通过报告上报RI、BI和CQI。
其中,在确定出RI、BI和CQI后,会在PUCCH上通过报告上报。
举例来说,基于Rel-13的Beamformed CSI-RS机制下的新传输模式的PUCCH反馈模式可以是PUCCH模式x-0,该反馈模式PUCCH模式x-0可以是现有的PUCCH模式1-0,或PUCCH模式2-0,可选地,也可以为一种反馈模式(如PUCCH模式x-0),该反馈模式的反馈内容包括:RI与BI中的至少一个,及对应的CQI。
其中,CQI可以为宽带CQI,也可以为宽带CQI+子带CQI,这里不做限定。
其中,PUCCH x-0的反馈模式的具体描述如下:
秩指示RI和或波束指示BI和信道质量指示CQI按照如下方式进行上报。
在BI/RI的上报时刻(仅适用于FD-MIMO传输模式,如TM11,或适用于用户设备被配置了信道状态信息类型报告B时):
用户在固定的S个子带上确定一个RI和/或BI值;
用户上报一个Type x的报告,此类型x的报告由一个RI和/或BI组成。
在CQI的上报时刻:
用户上报一个Type 4的报告,此类型4的报告由一个宽带CQI值组成,宽带CQI值为在固定S个子带上计算得到的值;其代表了RI=1或RI>1时第一个码字的信道质量。
作为可选的,UE在物理上行控制信道PUCCH上通过报告上报RI、BI和CQI之前还包括:
UE确定CSI-RS资源的数量;
UE根据空间复用的层数和/或CS-RS资源的数量确定RI和/或BI的大小。
该上报模式适用于下面的情形:
用户被配置了K(K>1)个CSI-RS资源,且同时被配置了信道状态信息报告类型一,如CSI report class B,所述K个CSI-RS资源中的每一个对应的天线端口数为1.此时用户的CSI上报可采用如上所述的反馈模式。
举例来说,对于此FD-MIMO的传输模式,可选地,可以是基于传统传输模式(Transmission Mode,TM)8,TM9和TM10的传输模式,或新传输模式TM11,CQI基于最近上报的周期RI和/或BI进行计算。对于其他传输模式,CQI基于秩1和默认的BI值进行计算。
其中,新定义的PUCCH上报类型x和上报类型4可表示如下表2至表4:
表2
Figure PCTCN2015094036-appb-000004
从表2中可以看出,RI的反馈比特数与空间复用层数相关,空间复用层数越大,反馈的比特数越多。
作为可选的,UE根据CSI-RS资源的数量确定RI和/或BI的大小包括:
当CSI-RS资源的数量为1时,RI和/或BI的大小与CSI-RS资源的端口数相对应;
当CSI-RS资源的数量大于1时,RI和/或BI的大小与CSI-RS资源的数量,空间复用的层数,和或CSI-RS资源的端口数相对应。
举例来说,表3中给出了在不同端口的情况下的BI的反馈比特数,表4给出了K的值不同时,BI的反馈比特数。其中,这里的BI是端口选择指示的意思,即对于CSI-RS资源的数量为1时,即对应K=1的情况,BI表示对所述CSI-RS资源内的端口的选择。
表3
Figure PCTCN2015094036-appb-000005
从表3中可以看出,当K=1时,BI的反馈或上报比特数与此CSI-RS资 源对应的天线端口数有关。
表4
Figure PCTCN2015094036-appb-000006
从表4可以看出,当K>1时,BI的反馈或上报bit数与此CSI-RS资源的个数K有关。
此外,在此反馈模式和其他PUCCH上报模式,如PUCCH 1-1或PUCCH 2-1的反馈模式中,不排除BI可以和RI进行联合上报。
作为可选的,UE在传输K个CSI-RS资源的宽带的S个子带上确定出一个预编码类型指示PTI;
UE确定CSI-RS资源的数量;
UE根据空间复用的层数和/或CS-RS资源的数量确定RI,BI和或PTI的大小。
即当上报的报告中还包括PTI时,也可按照根据空间复用的层数和/或CS-RS资源的数量确定PTI的大小,与前述确定BI的大小类似,此处不再赘述。
可选的,BI的上报周期大于等于RI的上报周期,报告的格式包括格式一、格式二和格式三,格式一的报告为BI的单独上报,格式二的报告为RI的上报,格式三的报告为BI和RI的联合上报,格式一的报告或格式三的报告的上报周期均为格式二的报告的上报周期的整数倍,格式一、格式二和格式三的报告合理搭配即可形成一个完整的上报周期。
又举例来说,对于PUCCH模式1-0和2-0之外的其他上报模式,如PUCCH 1-1或PUCCH 2-1的反馈模式中均分别包含反馈子模式一和反馈子模式二,反馈子模式一和反馈子模式采用不同的格式的报告上报BI,反馈子模式一中采用格式一或格式三的报告的上报BI,反馈子模式二中采用格式三或格式一的报告上报BI。
可以理解是,PUCCH 1-1或PUCCH 2-1的反馈模式,对于这两种反馈模 式来说,每种反馈模式均可包括两种不同的反馈子模式,即子反馈子模式一和反馈子模式二,其中反馈反馈子模式一中采用格式一或格式三的报告上报BI,反馈子模式二采用述格式三或格式一的报告上报BI,灵活的配置报告的上报格式,虽然上报的时序是相同的,但是在每一个上报时刻上报的报告的格式可以是不相同的,从而可根据每一个上报时刻的报告格式的不同将例如PUCCH 1-1或PUCCH 2-1的反馈模式均划分出反馈子模式一和反馈子模式二,从而可以更为灵活的对PUCCH反馈模式进行配置,提高用户反馈的自由度和灵活性,以及本发明实施例方案的可扩展性。
可选的,PUCCH反馈模式为PUCCH 1-1或PUCCH 2-1,PUCCH 1-1或PUCCH 2-1中均分别包含格式二的报告的上报和格式三的报告的上报,且格式三的报告的上报周期为格式二的报告的上报周期的整数倍。
举例来说,PUCCH 2-1的反馈模式中采用单码本结构的PMI上报情形,此时BI的上报方式的两种反馈子模式可采用如下表5所示:
反馈子模式一 BI RI CQI+PMI CQI+PMI
反馈子模式二 RI+BI   CQI+PMI CQI+PMI
从表5中可以看出,在反馈子模式一中采用BI单独上报的方式,即采用格式一的报告的上报方式,而在反馈子模式二中,采用该BI和该RI联合上报,在上报BI、RI或是BI和RI之后,会上报CQI和单码本中的PMI。
可选的,PUCCH反馈模式为PUCCH 1-1或PUCCH 2-1,格式二的报告还包括PMI,PMI指示预设的码本中的预编码矩阵,包含PMI的格式二的报告为RI和PMI联合上报。
又举例来说,采用PUCCH 2-1的反馈模式,码本为双码本结构,其中PMI与RI进行联合上报,具体的两种反馈子模式参见下表6:
表6
反馈子模式一 BI RI+PMI12 CQI+PMI11+PMI2 CQI+PMI11+PMI2
反馈子模式二 BI RI+PMI11 CQI+PMI12+PMI2 CQI+PMI12+PMI2
从表6中可以看出,在反馈子模式一中采用BI单独上报的方式,RI与双码本结构够一个PMI的一个维度上的PMI即PMI12联合上报,采用的上报格式为格式二,而在反馈子模式二中,RI与双码本结构中一个PMI的另一个维度上的PMI即PMI11联合上报,在上报BI、RI、PMI11或PMI12之后,会上 报CQI、PMI11和PMI2。
其中,可根据PMI11和PMI12在不同码本配置下的反馈比特数的差异进行PMI11与RI联合上报或者是PMI12与RI联合上报的上报方式的自由配置,如当PMI11的反馈比特数小于等于PMI12的反馈比特数时,将RI与PMI11进行联合编码,而当PMI12的反馈bit数小于等于PMI11的反馈bit数时,将RI与PMI12进行联合编码。
上述例子中,BI的上报周期为RI的上报周期的M倍,不同天线端口数下有不同的M配置,M为大于等于1的整数。
作为可选的,UE在传输K个CSI-RS资源的宽带的S个子带上确定出一个预编码类型指示PTI,PTI指示预编码的类型;
格式一的报告还包括PMI或PTI,包含PMI的格式一的报告为BI联合PMI上报,包含PTI的格式一的报告为BI与PTI联合上报;格式三的报告还包括PTI,包含PTI的格式三的报告为BI,RI与PTI联合上报。
举例来说,格式一的报告还包括PMI或PTI在各种PUCCH反馈模式下的上报格式和比特数如表7所示:
表7
Figure PCTCN2015094036-appb-000007
从表7中可以看出,包含PTI或者PMI的格式一的报告的反馈比特数与天线端口数,空间复用的层数以及CSI-RS资源的数量中的至少一个相关。
可以理解的是,当格式一的报告包括PMI或PTI,BI与PMI或PTI联合上报,当格式三的报告包括PTI,格式三的报告为BI,RI与PTI联合上报。
可选的,PUCCH的上报格式包括格式3a、格式6a和格式7,根据CSI-RS资源的数量和空间复用的层数之中的至少一个确定报告的反馈比特数。
举例来说,上报格式包括格式3a、格式6a和格式7的情形如下表8所示:
表8
Figure PCTCN2015094036-appb-000008
从表8中可以看出,每种上报类型下的反馈比特数与基站配置的每CSI-RS资源数目K,空间复用的层数L中的至少一个有关。
上报格式包括格式3a、格式6a和格式7的情形也可以为如下表9所示:
表9
Figure PCTCN2015094036-appb-000009
表9中,每种上报类型下的反馈比特数最大被限制到5(同现有技术中RI与其他CSI联合上报时的最大反馈比特数为5),从而可保证RI传输的可靠性。BI和RI联合上报的UCI域,BI和RI,PTI联合上报的UCI域及具体的反馈比特数详见下表10-1和下表10-2。
表10-1
Figure PCTCN2015094036-appb-000010
上表10-1为CSI class B类型下,且K>1时,BI和RI联合上报的UCI域及具体的反馈比特数。
表10-2
Figure PCTCN2015094036-appb-000011
上表10-2为CSI class B类型下,且K>1时,BI和RI,PTI联合上报的UCI域及具体的反馈比特数。
可选的,包含PMI的格式一的报告中的PMI为双码本结构中的第一预编码i1或单码本结构中的预编码i,方法还包括:
对预编码i或第一预编码i1下采样;
包含PMI的格式一的报告为BI和预编码i或第一预编码i1的联合上报。
举例来说,如下表11所示,表11是BI和i1联合编码为4bit的实例:
表11
Figure PCTCN2015094036-appb-000012
可以理解是,PMI可以是双码本结构中的第一预编码i1或者是单码本结构中的预编码i,对预编码i或第一预编码i1下采样,下采样即对于一个样值序 列间隔几个样值取样一次,得到新序列就是原序列的下采样,此处的样值为i或者i1均可进行下采样处理,而后可被包含在包含PMI的格式一的报告中,即将BI和i进行联合上报,或者将BI和i1进行联合上报。
可选的,PUCCH反馈模式为PUCCH 1-1,报告的格式包括格式一、格式二和格式三,格式一的报告为BI和RI联合上报,格式二的报告为RI上报,格式三的报告为宽带CQI和宽带PMI上报或格式三的报告为宽带CQI、宽带PMI1和宽带PMI2联合上报,格式一的报告的上报周期为格式二报告的上报周期的整数倍,格式二的报告的上报周期大于等于格式三的报告的上报周期,PMI、PMI1和PMI2均指示预设的码本中的预编码矩阵或预编码矩阵的组成部分。
举例来说,请参阅图4,图4是本发明实施例的测量与反馈方法的另一个实施例图,可以看出,在上述PUCCH 1-1中,天线端口数为2或4,格式三的报告为宽带CQI和宽带PMI上报。可以理解的是,在天线端口数为2或4的情形下,格式三的报告为宽带CQI和宽带PMI上报。具体的,上报顺序按照1、BI和RI联合上报,2、宽带PMI和宽带CQI上报,3、宽带CQI和宽带PMI上报,4、RI单独上报、5、宽带PMI和宽带CQI上报,6、宽带PMI和宽带CQI上报,7、BI和RI联合上报,按照1至6顺序依次完成一个完整周期的上报,其中2和3之间,5和6之间还可包括多次报告上报过程。
又举例来说,请参阅图5,图5是本发明实施例的测量与反馈方法的另一个实施例图,可以看出,在上述PUCCH 1-1中,天线端口数为4或8,格式三的报告为宽带CQI、宽带PMI1和宽带PMI2联合上报。可以理解的是,在天线端口数为4或8的情形下,格式三的报告为宽带CQI、宽带PMI1和宽带PMI2联合上报。具体的,上报顺序按照1、BI和RI联合上报,2、宽带PMI1、宽带PMI2和宽带CQI联合上报,3、宽带PMI1、宽带W2和CQI联合上报,4、宽带PMI1、宽带PMI2和宽带CQI联合上报,5、RI单独上报,6、宽带PMI1、宽带PMI2和CQI联合上报,7、宽带PMI1、宽带PMI2和宽带CQI联合上报。即按照1至7的顺序依次完成一个完整周期的上报,其中,6和7之间还可包括多次报告上报过程。
作为可选的,请参阅图6,图6是本发明实施例的测量与反馈方法的另一 个实施例图,可以看出,在上述PUCCH 2-1中,天线端口数为2或4,报告的格式包括格式一、格式二和格式三,格式一的报告为BI和RI联合上报,格式二的报告为宽带PMI和宽带CQI的上报,格式三的报告为RI的上报,格式一的报告的上报周期为格式二报告的上报周期的整数倍。具体的,上报顺序按照1、BI和RI联合上报,2、宽带PMI和宽带CQI联合上报,3、宽带PMI和宽带CQI联合上报,4、宽带PMI和宽带CQI联合上报,5、RI单独上报,6、宽带PMI和宽带CQI联合上报,7、宽带PMI和宽带CQI联合上报。即按照1至7的顺序依次完成一个完整周期的上报,其中,4和5之间,以及7与下一个周期之间还可包括多次报告上报过程。
作为可选的,请参阅图7,图7是本发明实施例的测量与反馈方法的另一个实施例图,可以看出,在上述PUCCH 2-1中,天线端口数为4或8,报告的格式包括格式一、格式二、格式三和格式四,格式一的报告为BI、RI和PTI联合上报,格式二的报告为RI和PTI上报,格式三的报告为宽带PMI1的上报,或格式三的报告为宽带CQI和宽带PMI2的上报,格式四的报告为宽带CQI和宽带PMI2的上报,或格式四的报告为子带CQI及子带PMI2的上报,格式一的报告的上报周期为格式二报告的上报周期的整数倍。具体的,上报顺序按照1、BI、RI和PTI联合上报,2、宽带PMI1上报,3、宽带PMI2和CQI联合上报,4、宽带PMI1上报,5、宽带PMI2和CQI联合上报,6、RI和PTI联合上报,7、宽带PMI1上报,8、宽带PMI2和CQI联合上报,其中,PTI=0。即按照1至8的顺序依次完成一个完整周期的上报。
或者,上报顺序按照1、BI、RI和PTI联合上报,2、宽带PMI2和CQI联合上报,3、子带PMI2和子带CQI联合上报,4、子带PMI2和子带CQI联合上报,5、RI和PTI联合上报,6、宽带PMI2和CQI联合上报,7、子带PMI2和子带CQI联合上报,其中,PTI=1。即按照1至7的顺序依次完成一个完整的周期的上报。
假定宽带CQI和PMI的上报周期为Npd,则上报宽带CQI/PMI的时刻为满足下述条件的子帧,其中nf和ns分别为帧号和时隙号,NOFFSET,CQI为CQI/PMI上报的初始时刻偏移量。
Figure PCTCN2015094036-appb-000013
假定RI的上报周期为Npd的整数倍,上报RI的时刻为满足下述条件的子帧,其中nf和ns分别为帧号和时隙号,NOFFSET,CQI为CQI/PMI上报的初始时刻偏移量,而NOFFSET,RI为RI上报的初始时刻偏移量。MRI(MRI>=1)为CQI和PMI上报周期的整数倍值。
Figure PCTCN2015094036-appb-000014
假定BI+RI或BI的上报周期为RI上报周期的整数倍,则上报BI+RI或BI的时刻为满足下述条件的子帧,其中nf和ns分别为帧号和时隙号,NOFFSET,CQI,NOFFSET,RI和MRI的含义同上,MBI(MBI>=1)为BI+RI或BI的上报周期除以RI上报周期的整数倍值,NOFFSET,BI为BI+RI或BI上报的初始时刻偏移量。

具体可见表10所示的对应关系:
表12
Figure PCTCN2015094036-appb-000016
其中,为保持IBI和IRI的域大小相同,也可将Npd或MRI的取值进行限制。如,将Npd的最大取值限制为40,或将MRI的最大值限制为8等,或MBI为整数倍的MRI值。
实施例2
针对Non-precoded CSI-RS机制,本发明实施例提供了一种信道状态信息的测量与反馈方法,请参阅图8,图8是本发明实施例的测量与反馈方法的一个实施例图,该方法可包括:
801、UE接收基站配置的第二信道状态信息报告类型以及基站下发的CSI-RS资源。
需要说明的是,第二信道状态信息报告类型在本发明实施例中为Non-precoded CSI-RS机制下UE反馈的信道状态信息的类型,即信道状态信息类型A,即CSI report class A。
可以理解是,UE首先会根据基站配置的第一信道状态信息报告类型获知需要进行的道状态信息的反馈类型,此处为按照Non-precoded CSI-RS机制进行反馈,在此机制下,UE会接收到基站下发的CSI-RS资源,用于后续确定RI和PMI。
802、UE在传输CSI-RS资源的宽带的S个子带上确定出一个秩指示RI、PMI11、PMI12和PMI2。
其中,S为大于等于1的整数,PMI11和PMI12分别为双码本结构中的第一个PMI的一个维度的PMI,PMI2为双码本结构之中的第二个PMI;
可以理解的是,在Non-precoded CSI-RS机制下,码本为新的2D码本,因此PMI包括双码本结构中的第一PMI和第二PMI,第一PMI由于是二维的,因此具有两个维度上的两个分量PMI11和PMI12,UE在确定PMI时,需要同时确定出三个PMI,即PMI11、PMI12和PMI2,最终的PMI指示的矩阵需要先由PMI11和PMI12各自指示的预编码矩阵结合形成PMI1指示的预编码矩阵,之后PMI指示的预编码矩阵再与PMI2指示的预编码矩阵结合,形成最终PMI指示的矩阵。
803、UE在S个子带上计算得到信道质量指示CQI。
可以理解的是,在确定出RI、PMI11、PMI12和PMI2之后,UE会在S个子带上计算得到CQI,该CQI的值反应了所选择信道的质量。
804、UE在PUCCH上通过报告上报RI、PMI11、PMI12、PMI2和CQI。
其中,在确定出RI、PMI11、PMI12、PMI2和CQI后,会在PUCCH上通过报告上报。
需要说明的是,此机制下主要针对PUCCH 1-1和PUCCH 2-1的反馈模式。
作为可选的,PUCCH反馈模式为PUCCH 1-1或PUCCH 2-1,上报PMI11和/或PMI12的报告的格式包括格式一、格式二和格式三,格式一的报告为单独上报PMI11或PMI12,格式二的报告为联合上报PMI11和RI,或格式二的报告为联合上报PMI12和RI,格式三的报告为联合上报PMI11、宽带PMI2 和宽带CQI,或格式三的报告为联合上报PMI12、宽带PMI2和宽带CQI。
可以看出,PUCCH 1-1的反馈模式还是PUCCH 2-1的反馈模式,均可具有三种上报的格式,即格式一的报告为单独上报PMI11或PMI12,格式二的报告为联合上报PMI11和RI,或格式二的报告为联合上报PMI12和RI,以及格式三的报告为联合上报PMI11、宽带PMI2和宽带CQI,或格式三的报告为联合上报PMI12、宽带PMI2和宽带CQI。格式二和格式三的报告均分别包括两种,对应于PUCCH 1-1和PUCCH 2-1的反馈模式的两种不同的反馈子模式。即反馈子模式一和反馈子模式二。
