- the transmitting end and the receiving end generally use multiple antennas to transmit and receive to obtain a higher rate.
- the data transmission performance of a multi-antenna system mainly depends on the measurement and feedback of channel information. Therefore, the measurement and feedback of channel information is the core content of multi-antenna technology; how to ensure the accuracy of channel measurement and channel information feedback, the rationality and robustness of feedback overhead become an important issue.
- CSI measurements and feedback were designed in the early Long Term Evolution (LTE) system version, but with higher accuracy requirements, pilots Overhead and feedback overhead and quantization complexity are not expected to increase significantly, so CSI's measurement and feedback techniques are becoming more complex to pursue higher quantization efficiency; and because of the need to target different scenarios (eg indoors, cities) Macro, dense urban, urban micro) and transmission mode (Open Loop multiple-input-multiple-output (OL-MIMO), semi-static MIMO, closed-loop MIMO, joint transmission, etc.), antenna configuration Better adaptability has also introduced a large number of new designs.

本申请基于申请号为201710184870.2、申请日为2017年03月24日的中国专利申请提出,并要求该中国专利申请的优先权,该中国专利申请的全部内容在此以引入方式并入本申请。
本发明涉及通信领域,具体而言,涉及一种信息发送、处理方法及装置、设备、终端、存储介质。
无线通信***中,发送端和接收端一般会采用多根天线发送和接收来获取更高的速率。而多天线***的数据传输性能好坏主要取决于信道信息的测量和反馈。因此信道信息的测量和反馈是多天线技术的核心内容;如何保障信道测量和信道信息反馈的准确度,反馈开销的合理性、鲁棒性成为了一个重要问题。
信道状态信息(Channel State Information,CSI)的测量和反馈在早期的长期演进(Long Term Evolution,LTE)***版本中是设计的得比较简单的,但随着精度要求越来越高,而导频开销和反馈开销及量化复杂度不希望有显著的增长,因此CSI的测量和反馈技术变得越来越复杂,以追求更高的量化效率;另外由于需要针对各种不同场景(比如室内,城市宏,密集城区,城市微)和传输模式(开环多输入多输出(Open Loop multiple-input-multiple-output,OL-MIMO),半静态MIMO,闭环MIMO,联合传输等)、天线配置都有较好的适应性,也引入了大量的新的设计。
下面介绍一些CSI,CSI反馈,CSI测量等一些概念。
信道状态信息CSI主要包括:信道质量指示信息(Channel Quality Indication,CQI)、预编码矩阵指示符(Precoding Matrix Indicator,PMI)和秩指示符(Rank Indicator,RI)。这里,其中,表示整个***带宽的CQI叫宽带CQI(WideBand CQI,WB CQI),代表子带的CQI叫子带CQI(SubBand CQI,SB CQI)。PMI指示根据码本的不同会有不同的表示,Release 8和Release 9的码本为Single Stage的码本,CSI只需要反馈一个预编码矩阵索引i;而在Release 10的8天线码本和Release 12的4天线码本,是1维的Dual Stage的码本,包括第一预编码矩阵索引i1和第二预编码矩阵索引i2,而在Release 13中引入了2维的Dual Stage的码本,其中第一预编码矩阵索引包括第一维度第一预编码矩阵索引i11和第二维度第一预编码矩阵索引i12,以及第二预编码矩阵索引i2;其中反馈的内容包括但不限于i/i1/i2/i11/i12。
随着MIMO计算的发展,需要反馈的CSI信息也越来越多,除了CQI/PMI/RI外,还包括,信道状态信息资源指示(CSI-RS Resource Indication,CRI)。对于码本,也出现了两种CSI反馈类别:
CSI反馈类别I:CSI feedback type I,它主要是指CSI中包含的预编码矩阵索引对应的码本是传统的码本,比如LTE中Release 13以前的码本,反馈的内容包括但不限于i/i1/i2/i11/i12
CSI反馈类别II:CSI feedback type II,它主要是指CSI中包含的码本集合里的码字是除了CSI feedback type I外的码字,比如线性合并的码字,它的每个码字通常由多个beam线性组合而成。或者信道相关矩阵,信道相关矩阵对应的特征向量。或者混合的CSI反馈。
所述CSI反馈类别I的信道状态信息参数包括至少以下预编码矩阵索引之一:预编码矩阵索引i;第一预编码矩阵索引i1和第二预编码矩阵索引i2; 第一维度第一预编码矩阵索引i11和第二维度第一预编码矩阵索引i12;
所述CSI反馈类别II的信道状态信息参数包括至少以下信息之一:波束索引信息,波束索引的偏置(这里的偏置是相对于第一组波束索引信息来说的),波束线性组合的幅度信息,波束线性组合的相位信息,波束线性组合的功率信息;波束线性组合的波束个数信息;波束线性组合的幅度的偏置信息,波束线性组合的相位偏置信息;信道相关矩阵信息;信道相关矩阵的特征值信息;信道相关矩阵的特征向量信息。
终端CSI的反馈在时域上主要存在三种方式:周期反馈,非周期反馈,半持续反馈。周期反馈主要是基站配置一个周期以及偏置,终端根据基站配置的周期和偏置对应的多个子帧上进行反馈,比如LTE中,基站可以配置终端对信道信息进行测量和量化,并通过上行控制信道(Physical Uplink Control Channel,PUCCH)对量化的CSI信息进行周期性的反馈。基站还可以在需要时,非周期性的突然触发终端进行CSI信息,包括RI/PMI/CQI,其中CQI包括WB CQI和SB CQI的上报。以克服周期反馈实时性不够高,CSI量化精度受限于控制信道开销的问题。它只在基站配置或者约定的子帧上反馈。另外还包括半持续的CSI反馈,它和周期CSI反馈类似,只是占用了周期CSI反馈的连续N>=1个反馈时刻/周期/子帧。其中反馈时刻/周期/子帧的起始位置和结束位置可以通过高层信令激活或者去激活。
信道信息的测量和反馈的类别有两种:分别为Class A和Class B。两种类别利用RRC信令进行半静态配置。
Class A:基站发送CSI-RS,一般为非预编码导频,用户基于该CSI-RS导频直接进行信道测量及CSI量化,得到RI/PMI/CQI。将这些内容在PUCCH或PUSCH上进行反馈,反馈内容较多,包括了宽带的波束方向。
Class B:基站发送的CSI-RS,一般为预编码导频,用户可能需要先进行预编码导频的选择,然后再基于选择的CSI-RS导频进行信道信息的量化 反馈,包括CSI-RS resource index(CRI)选择信息,以及选择的CSI-RS测量资源子集对应的RI/PMI/CQI信息。
相关技术中,CSI的反馈内容跟很多因素有关,不同的MIMO模式(Open Loop/Semi Open Loop/CL MIMO),CSI-RS类别(Class A/Class B/Hybrid CSI),天线配置,码本配置(Single Dual Codebook,Dual Codebook),CSI反馈的时域特性(周期反馈/非周期反馈/半持续反馈)都会影响CSI反馈包含的参数个数和参数内容.传统LTE的做法是针对这些不同内容的CSI参数,分别定义相应的CSI反馈模式(比如周期反馈模式Mode 1-0,Mode1-1,非周期反馈模式:Mode 1-2,Mode 2-0,Mode 2-2,Mode 3-0,Mode 3-1,Mode 3-2)并定义这些反馈模式上的反馈内容,只要反馈内容发送变化,就需要针对这个变化在不同的反馈模式上进行修改,但这种方法不够灵活,扩展性不好,不能适应NR的灵活的反馈需求。
针对相关技术中的上述技术问题,目前尚未提出有效的解决方案。

实施例7
本发明的实施例还提供了一种存储介质,该存储介质包括存储的程序, 其中,在上述程序运行时控制存储介质所在设备执行上述任一项所述的方法。
在一实施例中,上述存储介质可以被设置为存储用于执行实施例1或实施例2中的方法的步骤的程序代码。

在一实施例中,上述程序用于执行实施例1或实施例2中的方法的步骤。
在一实施例中,本实施例中的具体示例可以参考上述实施例及可选实施方式中所描述的示例,本实施例在此不再赘述。
为了更好的理解本发明实施例,以下结合优选实施例对本发明做进一步解释。
需要说明的是,在本发明实施例中,基站包括但不限于宏基站,微基站,微微基站,家庭基站,传输节点,无线热点,家庭基站,无线拉远。
终端包括数据卡、手机、笔记本电脑、个人电脑、平板电脑、个人数字助理、蓝牙等各种接收设备。
频域资源包括子载波、子载波组(比如LTE里的物理资源块包括12个子载波,物理资源块)、子载波集合(比如LTE里的子带)中的之一,所述子载波组包括多个子载波,所述子载波集合包括多个子载波组。在对信道状态信息进行反馈时,一般会基于一定的频域粒度进行的,一般来说反馈的频域粒度越小,越能精确地表述信道的质量,但这样反馈开销也会相应地也越大。反之,反馈的频域粒度越大,对信道的量化会差些,但反馈的 开销会小些。所以在无线通信***中,比如LTE中,或者New Radio(NR)中将频域的12个子载波称为一个物理资源块(Physical Resource Block,PRB),而k个物理资源块构成一个子带(Subband,SB),其中K的大小和***带宽有关,比如LTE中,定义的subband如表1所示。
表1
当然,不同的标准可能有不同的划分方式,但总的来说,它是包括多个物理资源块的。而对于NR来说,可能***有更大的***带宽,对于不同的用户来说可能占用了不同的带宽,这里把K个Subband聚合成一个部分带宽(Partial Band)将K个Subband上的CSI聚合在一起反馈。另外,有的参数它在整个***带宽上只反馈一个值,比如信道秩。把整个***带宽成为宽带(WideBand,WB),在宽带上反馈的CSI,成为宽带反馈。WB一般包括N个PRB,且一般来说,N>K>1。
基站需要指定终端在多大的带宽上进行测量,并反馈测量后的CSI,CSI的测量是针对一定的频域粒度进行的,比如基于WB进行测量得到宽带的CSI,基于子带CSI进行测量得到子带的CSI,基于部分带宽进行测量得到部分带宽的CSI。我们把这个叫做CSI的测量的频域粒度。反馈基于WB测量的CSI叫宽带信道状态信息反馈,宽带信道状态信息反馈所反馈的信道状态信息是基于宽带测量的。反馈基于SB测量的CSI叫子带信道状态信息反馈,子带信道状态信息所反馈的信道状态信息是基于一个子带测量的,对应着一个子带,叫做子带信道状态信息所反馈对应的子带。反馈 基于部分带宽测量的CSI,叫部分带宽信道状态信息反馈,部分带宽信道状态信息反馈所反馈的信道状态信息是基于一个部分带宽测量,它对应着1个或者多个子带,叫做部分带宽信道状态信息反馈对应的部分带宽包含的子带。当然在不同的协议中有不同的称呼,但只要是含义相同都在本发明的保护范围内。

所述接收波束指示是指,发送端可以通过当前参考信号和天线端口与UE反馈报告的参考信号(或基准参考信号)和天线端口的准共址(Quasi-Co-Location Indicator,QCL)假设来进行指示。所述的接收波束是指,无需指示的接收端的波束,或者发送端可以通过当前参考信号和天线端口与UE反馈报告的参考信号(或基准参考信号)和天线端口的准共址(QCL)指示下的接收端的波束资源;
所述波束对包括一个发送波束指示和一个接收波束指示的组合。
优选实施例1
本优选实施例给出的是CSI参数和SB/WB的比特图。
本优选实施例的无线通信***中,包括至少一个基站和至少一个终端(用户)。
基站配置信道状态信息参数集合(CSI参数集合),这个CSI参数集合中包括C个CSI参数,其中C为正整数,基站可以通过高层信令或者物理层信令将CSI参数集合中的C个CSI参数的内容和C的取值通知终端,也可以通过基站和终端约定的方式,确定C个CSI参数的内容和C的取值。C个CSI参数包括的内容,比如,是信道RI,预编码矩阵所以PMI(包括,i/i1/i2/i11/i12,beam索引等),CQI,宽带CQI,子带CQI,CRI等。C的最大取值可以基站自行确定,也可以根据UE的能力确定,还可以根据传输模式确定。
基站和终端通过约定的方式,或者基站自身决定的方式,确定***的带宽包括Nrb个物理资源块,并将整个带宽划分成Nsb个子带SB,每个SB包括大于1个的物理资源块。基站配置C个CSI参数,并通过CSI参数集合指示信息指示所述的C个CSI参数是否需要反馈,是宽带反馈还是子带反馈,其中的宽带反馈是指在这个***带宽上只反馈一个宽带的CSI,比如RI,CRI等,当然PMI和CQI也可以是宽带反馈的。
所述的CSI参数集合指示信息是一个比特图,比特图的行表示CSI参数,而列表示CSI参数频域反馈的粒度(SB,WB)/子带索引,当然,也可以是行表示CSI参数反馈的粒度(SB,WB)/子带索引,而列表示CSI参数。不失一般性,这里假设Nsb=4,对于Nsb取其它值的情况,可以类似得到。下面给出一些优选的比特图实施例,需要说明的是,这里的比特图(第一个比特图)中,每个比特的取值是可以基站配置的,这里只是列出了其中的一种情况,不对本发明的权利范围构成限制。
A)表2的比特图中,包括3个CSI参数:PMI索引i,RI和WB CQI。
表2
SB1 | SB2 | SB 3 | SB 4 | WB | |
i | 1 | 0 | 1 | 0 | 1 |
RI | 0 | 0 | 0 | 0 | 1 |
WB CQI | 0 | 0 | 0 | 0 | 1 |
B)表3的比特图中,包括4个CSI参数:PMI索引i1/(i11/i12),i2,RI和WB CQI。
表3
SB1 | SB2 | SB 3 | SB 4 | WB | |
i1(i11/i12) | 0 | 0 | 0 | 0 | 1 |
i2 | 1 | 0 | 1 | 0 | 1 |
RI | 0 | 0 | 0 | 0 | 1 |
WB CQI | 0 | 0 | 0 | 0 | 1 |
C)表4的比特图中,包括5个CSI参数:PMI索引i1/(i11/i12),i2,RI和WB CQI,SBCQI。
表4
SB1 | SB2 | SB 3 | SB 4 | WB | |
i1(i11/i12) | 0 | 0 | 0 | 0 | 1 |
i2 | 1 | 0 | 1 | 0 | 1 |
RI | 0 | 0 | 0 | 0 | 1 |
WB CQI | 0 | 0 | 0 | 0 | 1 |
SB CQI | 1 | 1 | 1 | 1 | 0 |
D)表5的比特图中,包括6个CSI参数:PMI索引i1/(i11/i12),i2,RI和WB CQI,SBCQI,CRI。
表5
SB1 | SB2 | SB 3 | SB 4 | WB | |
i1(i11/i12) | 0 | 0 | 0 | 0 | 1 |
i2 | 1 | 0 | 1 | 0 | 1 |
RI | 0 | 0 | 0 | 0 | 1 |
WB CQI | 0 | 0 | 0 | 0 | 1 |
SB CQI | 1 | 1 | 1 | 1 | 0 |
CRI | 0 | 0 | 0 | 0 | 1 |
E)表6的比特图中,包括C个CSI参数,比如PMI索引i1/(i11/i12),i2,RI和WB CQI,SBCQI,CRI,波束索引,波束偏置,波束线性组合的幅度,波束线性组合的幅度,信道协方差矩阵,信道协方差矩阵的特征向量等跟CSI相关的参数,这里不一一列举。并在这些参数中取其中的C个,表示为CSI参数1,CSI参数2,…,CSI参数C。
表6
SB1 | SB2 | SB 3 | SB 4 | WB | |
CSI参数1 | 0 | 0 | 0 | 0 | 1 |
CSI参数2 | 1 | 0 | 1 | 0 | 1 |
… | … | … | … | … | … |
CSI参数C-1 | 0 | 0 | 0 | 0 | 1 |
CSI参数C | 1 | 1 | 1 | 1 | 0 |
需要说明的是,如果一个CSI参数对应的比特图中,包括连续的K个SB对应的值为1,则可以将K个SB聚合成一个部分带宽PB,并在这些PB上只反馈一个CSI,而不是针对每个SB分别反馈一个CSI,比如表6中的CSI参数C中SB1,SB2,SB3,SB4的比特图的取值都是1,所以可以将连续的K个SB上的CSI参数C进行聚合,只反馈1个CSI参数C,比如K取值为2时,SB1和SB2聚合为一个PB1,并且反馈一个CSI参数C,而SB3和SB4聚合成一个PB2,反馈一个CSI参数C,如果K的取值为4,那么SB1~SB4聚合成一个PB进行反馈一个CSI参数C。其中K的大小可以根据UE的能力,或者基站配置确定。
需要说明的是,这里表1~表6中的比特图中的比特状态为1和0,其中1表示在所述的SB上或者WB需要反馈CSI参数,而0表示在所述的SB上或者WB不需要反馈CSI参数。但这只是一种约定,在本文档中如果 不特别说明,都是以这种方式进行约定。但在其它的文档或者方法中也可以约定其它的含义,比如0表示在所述的SB上或者WB需要反馈CSI参数,而1表示在所述的SB上或者WB不需要反馈CSI参数,都在本发明的保护范围内。
终端接收终端配置的CSI参数指示信息,即一个比特图,比如表1~表6中的一个比特图。其中C个CSI参数的内容和C的取值可以是接收基站通过高层信令确定的,也可以是基站和终端约定的。
终端通过CSI参数指示信息,确定需要反馈的CSI参数,以及这个CSI参数是子带还是宽带反馈,并且在哪些子带上反馈。比如,对于每个CSI参数集合中的一个参数,比如CSI参数1(i/i1/i11+i12),它所在的行中查找取值为1的列,从而确定,它在SB1~SB4上都是0,从而,不需要在子带SB1~SB4上反馈,而只需要在WB上反馈。又比如CSI参数C(SB CQI或i2),它在SB1~SB4上的取值都是1,所以需要在SB1~SB4上分别测量和反馈CSI参数C。但为了减小反馈量,可以对连续K个SB上取值为1的SB进行聚合,比如SB1和SB2聚合成一个部分带宽PB,并在这个PB上反馈一个CSI参数C。其中K的取值可以是接收基站通过高层信令配置确定,或者基站和终端约定的方式确定,或者根据UE能力确定的。
需要说明的是,为了减小比特图的开销,可以对CSI参数集合里的参数根据参数的频域反馈粒度的特性进行分类,比如RI,CRI,i1这些反馈粒度为宽带的参数为一个宽带CSI参数子集合,而子带反馈的i2,线性码本组合的相位信息等参数可以组合成一个子带CSI参数子集合。而比特图中可以只包含子带CSI参数子集合如表7所示,在这里没有最后一列WB的比特图,或者宽带CSI参数子集合如表8所示,只有一列WB的比特图,用于表示对应的CSI参数是否需要反馈。
表7
SB1 | SB2 | SB 3 | SB 4 |
CSI参数1 | 0 | 1 | 0 | 0 |
CSI参数2 | 1 | 0 | 1 | 0 |
… | … | … | … | … |
CSI参数C-1 | 0 | 1 | 1 | 0 |
CSI参数C | 1 | 1 | 1 | 1 |
表8
WB | |
CSI参数1 | 0 |
CSI参数2 | 1 |
… | … |
CSI参数C-1 | 0 |
CSI参数C | 1 |
这样可以减小比特图的大小,其中表7中的CSI参数都是子带反馈的CSI参数,而表8中的CSI参数都是宽带反馈的CSI参数。

基站和终端通过约定的方式,或者基站自身决定的方式,确定***的带宽包括Nrb个物理资源块,并将整个带宽划分成Nsb个子带SB,每个SB包括大于1个的物理资源块。基站配置C个CSI参数,并通过CSI参数集合指示信息指示所述的C个CSI参数是否需要反馈,是部分带宽反馈还是子带反馈,其中的部分带宽反馈是指在包含K个子带的频域粒度上反馈一个部分带宽的的CSI,比如RI,CRI等,当然PMI和CQI也可以是部分带宽反馈的。而其中宽带反馈可以看成K=Nsb的特殊情况。这里不失一般性,将***带宽分成M个部分带宽PB,其中第i个PB可以包含Ki个SB,每个PB包含的SB个数可以不同,也可以相同,Ki,i=1,…,M是正整数,每个PB包含的SB也可以有相同的SB,比如将一个有Nsb=4个SB的带宽分成两个PB,其中PB1={SB1,SB2},PB2={SB3,SB4},这里K1=K2=2;也可以是PB1={SB1},PB2={SB2,SB3,SB4},这里K1=1,K2=3;还可以是PB1={SB1,SB2,SB3},PB2={SB2,SB3,SB4},这里K1=3,K2=3。PB的划分,以及大小可以基站确定,并通过高层信令配置给终端,也可以通过终端能力确定,或者基站和终端约定的方式确定。或者它的大小可以根据CSI-RS(也可以是SRS或者其它参考导频)导频的带宽确定,即小于等于CSI-RS导频的带宽。
所述的CSI参数集合指示信息是一个比特图,比特图的行表示CSI参数,而列表示CSI参数频域反馈的粒度(SB,PB)或者SB/PB的子带索引,这里的比特图的行和列可以互换。不失一般性,这里假设Nsb=4,对于Nsb取其它值的情况,可以类似得到。下面给出一些优选的比特图实施例,需要说明的是,这里的比特图中,每个比特的取值是可以基站配置的,这里只是列出了其中的一种情况,不对本发明的权利范围构成限制。
A)表9的比特图(这里称为第二比特图)中,包括C个CSI参数,比如PMI索引i1/(i11/i12),i2,RI和WB CQI,SBCQI,CRI,波束索引,波束偏置, 波束线性组合的幅度,波束线性组合的幅度,信道协方差矩阵,信道协方差矩阵的特征向量等跟CSI相关的参数,这里不一一列举。并在这些参数中取其中的C个,表示为CSI参数1,CSI参数2,…,CSI参数C,而列只有PB索引,这里以M=2个PB为例,其中PB1={SB1,SB2,SB3},PB2={SB2,SB3,SB4},这里K1=3,K2=3。对于M取其它值,以及每个PB包含的SB个数以及划分可以类似得到。为了描述方便,这里取C=4,对于其它的C的取值,以及CSI参数的内容,可以类似得到。
表9
PB1 | PB2 | |
CSI参数1 | 0 | 0 |
CSI参数2 | 1 | 0 |
CSI参数3 | 0 | 1 |
CSI参数4 | 1 | 1 |
为了进一步刻画信道状态信息,可以对表9中的比特图进一步地进行SB的指示,即进一步配置第三比特图,其中的第三比特图为每个PB中,比特图取值为1对应的参数与子带集合的比特图。比如对于PB1,CSI参数2和CSI参数4的取值为1,那么对CSI参数2和CSI参数4与子带集合1(比如PB1对应的SB1,SB2,SB3)的比特图为表10所示。
表10
SB1 | SB2 | SB3 | |
CSI参数2 | 0 | 0 | 1 |
CSI参数4 | 1 | 0 | 1 |
而对于PB2,CSI参数3和CSI参数4对应的比特图中的状态取值为1,那么对于CSI参数3和CSI参数4与子带集合2(比如PB2对应的SB2,SB3,SB4)的比特图。如表11所示。
表11
SB2 | SB3 | SB4 | |
CSI参数3 | 0 | 1 | 1 |
CSI参数4 | 1 | 1 | 1 |
其中表10和表11的比特图中的状态取值只是一个示例,可以是基站根据需要来配置。
需要说明的是,表10中子带集合可以只包含PB1的部分子带(比如SB1和SB2),也可以是,PB1只是子带集合1的一个子集合(比如,SB1,SB2,SB3,SB4)。同样的,子带集合2可以只包含PB2的子带的一个子集合,也可以是PB2只是子带集合2的一个子集合。
终端接收终端配置的CSI参数指示信息,即一个第二比特图和/或M个第三比特图,比如表9~表11中的一个比特图。其中C个CSI参数的内容和C的取值可以是接收基站通过高层信令确定的,也可以是基站和终端约定的。
终端通过CSI参数指示信息,确定需要反馈的CSI参数,以及这个CSI参数是子带还是宽带反馈,并且在哪些子带上反馈。
在没有接收到第三比特图的情况下,比如,在第二比特图中(比如表9)它所在的行中查找取值为1的行,从而确定需要反馈的CSI参数,从而计算并在这个PB上反馈取值为1对应的CSI参数,比如对于PB1,需要计算并反馈CSI参数2和CSI参数4,而PB2,需要计算并反馈CSI参数3和CSI参数4。
在有接收到第三比特图的情况下,比如,在第二比特图中(比如表9)它所在的行中查找取值为1的行,从而确定需要反馈的CSI参数,并进一步根据第三比特图确定需要计算和反馈哪些SB上的CSI参数。比如,比如查表10,获得CSI参数2需要在SB3上反馈,而CSI参数4需要在SB1和SB3上反馈。同样地,对于PB2,CSI参数3需要在SB3和SB4上反馈,而CSI参数4需要在SB2和SB3,SB4上反馈。
需要说明的是,这里WB反馈可以看出PB反馈的一种特别情况,即PB和WB包含相同的物理资源块数目。每个PB包含的子带数目可以由基站自身确定,并通过信令通知终端,也可以根据用户的能力确定,或者根据一些参考信号的带宽确定,比如探测参考信号SRS,信道状态信息参考信号CSI-RS。
优选实施例3
本优选实施例给出了CSI参数bit图,并指明每个参数的属性(SB/WB/PB)
基站发送CSI参数集合指示信息,所述的CSI参数集合指示信息是一张比特图,用于指示CSI参数集合中的参数在频域的反馈粒度,以及是否需要反馈。所述的比特图是第四比特图,它的行是CSI参数列表。对于包含C个CSI参数的第四比特图如表12所示,其中第一列表示CSI参数的名称,而第二列中的数字0表示所对应的CSI参数不需要测量和反馈,1表示所对应的CSI参数不需要测量和反馈.同样的,比特图也可以表示成行的形式,即列表示CSI参数的名称。在基站配置参数的时候,可能只有数字这列,而省去CSI参数名称这一列。
表12
CSI参数1 | 0 |
CSI参数2 | 1 |
… | … |
CSI参数C-1 | 0 |
CSI参数C | 1 |
这里的CSI参数1~CSI参数C都是CSI参数集合中的一个CSI参数,比如可以是RI,CRI,beam索引,预编码矩阵索引,相位索引,幅度索引信道相关矩阵等。
这里,C的大小以及CSI参数集合中包含的参数,可以是基站通过高 层信令配置的,也可以是基站和终端通过约定的方式确定的。
比特图中每个CSI参数的频域粒度(包括WB,PB,SB)可以由约定的方式确定,比如CRI,RI,i1,beam索引等可以是宽带的/部分带宽的,而SB CQI,i2等参数可以是子带的/部分带宽的。也可以是基站通过高层信令配置通知终端的。
终端接收CSI参数集合指示信息,比如表12所示的比特图,并通过这个比特图确定哪些CSI参数是需要测量和反馈的,比如对比特图中数字为1对应的CSI参数是进行测量和反馈的。而每个CSI参数的频域粒度特性可以是接收基站配置的高层信令确定的,也可以是基站和终端约定的方式确定的。
优选实施例4
本优选实施例给出了CSI参数与时域反馈方式的比特图。
基站发送CSI参数集合指示信息,所述的CSI参数集合指示信息是一张比特图,用于指示CSI参数集合中的参数在时域反馈方式,其中时域反馈方式包括周期反馈,非周期反馈,半持续反馈中的一种或者多种。所述的比特图是称为第四比特图,它的行是CSI参数列表,列表示CSI的时域反馈方式。对于包含C个CSI参数的第四比特图如表13所示。
表13
周期反馈 | 非周期反馈 | 半持续反馈 | |
CSI参数1 | 0 | 1 | 0 |
CSI参数2 | 0 | 0 | 1 |
… | … | … | … |
CSI参数C-1 | 1 | 0 | 0 |
CSI参数C | 0 | 0 | 1 |
本优选实施例的CSI参数1~CSI参数C都是CSI参数集合中的一个CSI参数,比如可以是RI,CRI,beam索引,预编码矩阵索引,相位索引,幅度索引信道相关矩阵等。
在本优选实施例中,C的大小以及CSI参数集合中包含的参数,可以是基站通过高层信令配置的,也可以是基站和终端通过约定的方式确定的。
比特图中的状态1表示对应的CSI参数用对应的时域反馈方式进行反馈,比如CSI参数1用非周期反馈方式进行反馈,而CSI参数2用半持续反馈的方式进行反馈等。
终端接收CSI参数集合指示信息,比如表13所示的比特图,并通过这个比特图确定哪些CSI参数是在时域上是怎么反馈的。比特图中的状态1表示对应的CSI参数用对应的时域反馈方式进行反馈,比如CSI参数1用非周期反馈方式进行反馈,而CSI参数2用半持续反馈的方式进行反馈等。
