Description

信道信息的配置方法及装置、反馈方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种信道信息的配置方法及装置、反馈方法及装置。
背景技术
多天通信预编码与反馈技术基础原理介绍：在无线通信系统中，发送端和接收端采取空间复用的方式使用多根天线来获取更高的速率。相对于一般的空间复用方法，一种增强的技术是接收端反馈给发送端信道信息，发送端根据获得的信道信息使用发射预编码技术，可以极大地提高传输性能。对于单用户多输入多输出(SU-MIMO，其中的MIMO表示Multi-input Multi-output，多输入多输出)中，直接使用信道特征矢量信息进行预编码；对于多用户MIMO(MU-MIMO)中，需要比较准确的信道信息。在3GPP长期演进(Long Term Evolution，简称为LTE)计划中，信道信息的反馈主要是利用较简单的单一码本的反馈方法，而MIMO的发射预编码技术的性能更依赖于其中码本反馈的准确度。
这里将基于码本的信道信息量化反馈的基本原理简要阐述如下：假设有限反馈信道容量为Bbps/Hz，那么可用的码字的个数为N＝2B个。信道矩阵的特征矢量空间经过量化构成码本空间
Figure PCTCN2016070074-appb-000001
发射端与接收端共同保存或实时产生此码本
Figure PCTCN2016070074-appb-000002
(发射端和收收端相同)。对每次信道实现H，接收端根据一定准则从码本空间
Figure PCTCN2016070074-appb-000003
中选择一个与信道实现H最匹配的码字
Figure PCTCN2016070074-appb-000004
并将该码字
Figure PCTCN2016070074-appb-000005
的序号i(码字序号)反馈回发射端。这里，码字序号称为码本中的预编码矩阵指示符(Precoding Matrix Indicator，简称为PMI)。发射端根据此序号i找到相应的预编码码字
Figure PCTCN2016070074-appb-000006
从而也获得相应的信道信息，
Figure PCTCN2016070074-appb-000007
表示了信道的特征矢量信息。这里信道信道H一般是根据信道测量导频进行信道测量获得的。
一般来说码本空间
Figure PCTCN2016070074-appb-000008
可以进一步地被划分为多个Rank对应的码本，每个Rank下会对应多个码字来量化该Rank下信道特征矢量构成的预编码矩阵。由于信道的Rank和非零特征矢量个数是相等的，因此，一般来说Rank为N时码字都会有N列。所以，码本空间
Figure PCTCN2016070074-appb-000009
可按Rank的不同分为多个子码本，表1为码本按Rank分为多个子码本示意，如表1所示，
Figure PCTCN2016070074-appb-000010
Figure PCTCN2016070074-appb-000011
表1
其中，在Rank>1时需要存储的码字都为矩阵形式，其中LTE协议中的码本就是采用的这种码本量化的反馈方法，实际上LTE中预编码码本和信道信息量化码本含义是一样的。在下文中，为了统一起见，矢量也可以看成一个维度为1的矩阵。
3GPP协议关于信道状态信息的反馈内容介绍：以下是一些LTE中与信道信息反馈相关的内容，本发明较为关注的内容是信道的秩指示符(Rank Indication，简称为RI)信息和PMI信息，信道质量指示信息(Channel quality indication，简称为CQI)可以附带PMI一起反馈。信道状态信息反馈包括：信道质量指示信息(Channel quality indication，简称为CQI)、预编码矩阵指示符(Precoding Matrix Indicator，简称为PMI)和秩指示符RI。
CQI为衡量下行信道质量好坏的一个指标。在36-213协议中CQI用0～15的整数值来表示，分别代表了不同的CQI等级，不同CQI对应着各自的调制方式和编码码率(MCS)。RI用于描述空间独立信道的个数，对应信道响应矩阵的秩。在开环空间复用和闭环空间复用模式下，需要UE反馈RI信息，其他模式下不需要反馈RI信息。信道矩阵的秩和层数对应。PMI反馈的是最佳预编码信息，基于索引反馈，指示约定的码本中最匹配当前信道的特征的码字。
3GPP还引入了信道状态信息(Channel State Information，简称为CSI)process(进程)的概念，基站可以为终端配置多个CSI process，每个CSI process相当于一个反馈进程，各个CSI process之间是独立的，可以分别进行参数配置
一个CSI process包括信道测量部分的配置和干扰测量部分以及反馈模式的配置，信道测量部分一般指定一套非零功率的CSI测量导频(Non Zero Power CSI-RS)用于信道测量，干扰测量一般指定一套IMR资源配置用于干扰测量，IMR资源一般可以是一套零功率的CSI-RS(Zero Power CSI-RS)。
相关技术中，导频一般默认是全维导频，即物理天线与测量导频端口是一对一的映射，信道测量的方法比较简单，而基于RI/PMI/CQI的隐式反馈方法的CSI量化反馈技术也比较单一。
随着MIMO技术的发展，涌现出了大量的新的技术，例如基于预编码CSI-RS导频的测量技术，新的反馈技术如水平垂直分维反馈技术等。新的一些技术虽然在部分场景下具有很好的性能，但是在有些场景下会带来性能损失，因此能够非常灵活的进行各种测量和反馈就变得非常重要，才能保障很好的性能同时保障良好的测量和反馈鲁棒性。
针对相关技术中导频的测量与反馈技术不够灵活的问题，目前尚未提出有效的解决方案。

通过本发明中描述的方式，通过多个线程实现了多种信道信息的测量，能够使得终端侧有非常好的反馈灵活性，避免了单线程时鲁棒性差，性能不佳的问题，同时，有效的控制了反馈的开销。
下面通过本可选实施例的具体实施例对本可选实施例进行详细举例说明；
首选对本信道信息反馈的配置方法进行描述，该方法的步骤包括：
步骤S301：基站为一个CSI反馈(Process)进程配置Q个CSI测量线程(thread)
这里一个CSI测量线程对应完成CSI测量所需要的一套CSI测量配置，至少包括信道测量部分的配置，反馈测量部分的配置，以及反馈模式等其他配置。
相关技术中的CSI进程定义如下：CSI进程(基于进程分配反馈资源只包含1个CSI测量线程)包括：信道测量部分、干扰测量部分以及其他配置。
而本可选实施例提供的CSI进程的定义如下：CSI进程(基于进程分配反馈资源)包括：Q个CSI测量线程，每个CSI测量线程都包括信道测量部分、干扰测量部分以及其他配置。
与相关技术中的CSI进程定义不同，相关技术中的CSI进程可以理解只包含一个线程。本可选实施例提供的的CSI进程中包括多个线程，每个线程都需要配置或约定与之对应的信道测量与干扰测量及反馈模式等相关的配置。
步骤S302：终端从Q个CSI测量线程中选出Y个线程，并按照Y个线程对应配置进行CSI测量及CSI反馈，其中，Y<Q；
由于反馈资源是基于进程分配的，各线程不一定均对应于反馈资源；部分线程的CSI测量后得到的量化结果需要反馈，但部分线程对应的CSI测量结果并不需要反馈；
基站为终端配置Q个CSI测量线程，这里的Q个CSI测量线程一般是对应于Q种不同的量化和/或反馈方法。Q为大于1的整数，这样就可以支持多种CSI测量和反馈之间的动态选择，但为了避免过高的复杂度，Q可选为2、3或4，Q的取值可以通过基站与终端预先约定或基站通过信令配置给基站。这里，不同的CSI Process对应的Q的取值可以独立配置。
其中，上述不同可以体现在以下方面之一：Q个CSI测量线程信道测量方面的不同；Q个CSI测量线程干扰测量方面的不同；Q个CSI测量线程CSI量化方法的不同；Q个CSI测量线程CSI反馈方法的不同；Q个CSI测量线程对应的RANK或LAYER组不同。
基于上述本可选实施例的信道信息的配置方法，下面通过不同的应用场景具体的实施例进行说明；
可选实施例1：各线程信道测量方面的不同；
比如配置的测量导频不同，这里的测量导频不同包括：不同的导频端口数、不同的导频功率、不同的导频周期、不同的导频密度、不同的导频频域位置、不同的导频类型等等。
对于上述的测量导频不同进行举例说明：如2个CSI测量线程，其中：
A)线程1配置端口数为N1，线程2配置端口数为N2；其中N1,N2为不相等的正整数。
B)线程1配置发送功率为Power1，线程2配置发送功率为Power2；其中Power1和Power2为不相等的正数。
C)线程1配置导频周期为T1，线程2配置导频周期为T2；其中T1和T2为不相等的正整数。
D)线程1在一个资源块里的导频RE个数配置N1个，线程2在一个资源块里的导频RE个数配置N2个；其中N1,N2为不相等的正整数。
E)线程1配置的导频类型为波束导频，线程2配置的导频类型为非波束导频。
F)线程1配置的波束导频的波束半功率宽度为W1，线程2配置的波束导频的波束半功率宽度为W2，其中，W1和W2为不同的正数。
G)线程1发送导频所用的天线集合为W1，线程2发送导频所用的天线集合为W2，其中，W1和W2集合里至少有一个元素不同。
H)线程1配置的形成波束导频的波束的个数N1个，线程2配置的形成波束导频的波束的个数为N2个，其中，N1,N2为不相等的正整数。
基站可以将Q个CSI测量线程配置为全部独立的信道测量，即Q个CSI测量线程配置了Q套信道测量导频。或者，
基站可以将Q个CSI测量线程配置为部分独立的信道测量，即Q个CSI测量线程配置了少于Q套信道测量导频。即至少有2个进程配置了相同的信道测量导频。
最后需要说明的是，完全相同的信道测量也是可以的，但此时其他方面需要有不 同。
可选实施例2：各线程干扰测量方面的不同；
本可选实施例2涉及的干扰测量资源不同包括：不同的干扰测量RE个数：不同的干扰测量位置：不同的干扰测量资源的周期等。
对于该干扰测量资源的不同进行举例说明：如2个CSI测量线程；
A)线程1配置端口数为N1，线程2配置端口数为N2；其中N1,N2为不相等的正整数。
B)线程1配置发送功率为Power1，线程2配置发送功率为Power2；其中Power1和Power2为不相等的正数。
C)线程1配置导频周期为T1，线程2配置导频周期为T2，；其中T1和T2为不相等的正整数。
D)线程1在一个资源块里的导频RE个数配置N1个，线程2在一个资源块里的导频RE个数配置N2个；其中N1,N2为不相等的正整数。
E)线程1配置的导频类型为波束导频，线程2配置的导频类型为非波束导频。
F)线程1配置的波束导频的波束半功率宽度为W1，线程2配置的波束导频的波束半功率宽度为W2，其中，W1和W2为不同的正数。
G)线程1发送导频所用的天线集合为W1，线程2发送导频所用的天线集合为W2，其中，W1和W2集合里至少有一个元素不同。
H)线程1配置的形成波束导频的波束的个数N1个，线程2配置的形成波束导频的波束的个数为N2个，其中，N1,N2为不相等的正整数。
基站可以将Q个CSI测量线程配置为全部独立的干扰测量，即Q个CSI测量线程配置了Q套干扰测量导频；或者，
基站可以将Q个CSI测量线程配置为部分独立的干扰测量，即Q个CSI测量线程配置了少于Q套干扰测量导频。即至少有2个进程配置了相同的干扰测量导频。
最后需要说明的是，在本可选实施例中完全相同的干扰测量也是可以的，但此时其他方面需要有不同。
可选实施例3：各线程CSI的量化方法的不同；
基站为Q个CSI测量线程配置不同的CQI的计算方法；
比如：线程i的信道测量导频为一个4端口的CSI-RS，终端基于4端口的测量导频假设4个端口按照传输分集技术进行传输，进而得到线程i的一个传输分集CQI，线程j的信道测量导频为一个2端口的CSI-RS，终端基于2个端口的测量导频假设2个端口按照2层预编码技术进行传输，进而得到与之对应的2个CQI。
还可以是，线程i的信道测量导频为一个4端口的CSI-RS，终端基于4端口的测量导频假设4个端口按照传输分集技术进行传输，进而得到线程i的一个传输分集CQI，线程j的信道测量导频为一个4端口的CSI-RS，终端基于4个端口的测量导频假设4个端口按照4层预编码技术进行传输，进而得到与之对应的2个CQI。
还可以是，线程i的信道测量导频为一个4端口的CSI-RS，终端基于4端口的测量导频假设4个端口按照传输分集技术进行传输，进而得到线程i的一个传输分集CQI，线程j的信道测量导频为一个4端口的CSI-RS，终端基于4个端口进行端口选择，进而得到最佳的端口并上报该端口对应的CQI。
基站为Q个CSI测量线程配置不同的RANK或LAYER的计算方法；
比如：基站为终端配置线程i的RANK或LAYER由其对应的CSI-RS导频中端口个数或DMRS(数据专有解调导频)导频端口个数计算确定，线程j的RANK或LAYER由基站根据当前信道矩阵H最适合的传输层数确定，一般是假设闭环预编码传输，由终端遍历各种层数的假设，比较不同传输层时的性能，并选取最佳的传输层数。
基站为Q个CSI测量线程配置不同的码本模型；
比如：线程i的信道测量导频为一个16端口的CSI-RS，线程j的信道测量导频也为相同的CSI-RS，线程k的信道测量导频也为相同的CSI-RS。基站为终端配置对于线程i，j，k分别使用如下的码字模型1、2、3进行量化反馈；其中模型1为线程i，模型2为线程j，模型3为线程k。

线程i，4bit的码本，每个RANK或LAYER下的码本包含16个码字；
