背景技术
无线通信系统中,发送端和接收端一般会采用采多根天线发送和接收来获取更高的速率。多天线技术的一个原理是利用信道的一些特征来形成匹配信道特征的多层传输,信号的辐射方向非常有针对性,能够有效的提升系统性能,在不增加带宽和功率的基础上就获得显著的性能提升,是一个非常有前景的技术,在目前的系统中广泛应用。多天线系统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,开销、鲁棒性成为了一个重要问题。
信道状态信息(Channel State Information,简称为CSI)的测量和反馈在早期的长期演进(Long Term Evolution,简称为LTE)系统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、天线配置都有较好的适应性,也引入了大量的新的设计。下面介绍一些与CSI测量和量化反馈相关的基本内容:
CSI测量参考信号:
信道状态信息参考信号(Channel State Information Reference Signal简称为CSI-RS)可以被用于下行信道信息的测量。CSI-RS分为两类:非预编码导频(Non-Precede CSI-RS,简称为NP CSI-RS)、预编码导频(Beam Formed CSI-RS,简称为BFed CSI-RS)。对于NP CSI-RS,基站通过在所有端口发送导频、用户接受导频并测量、反馈信道信息的方法获取信道状态信息。对于BFed CSI-RS,基站为不同端口组配置预编码矩阵,并将在K套CSI-RS资源上将CSI-RS加载在预编码矩阵上发送(K≥1),用户测量等效信道并反馈最好的CSI-RS资源上的CSI。
CSI反馈方式:
终端CSI的反馈主要存在两种方式: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,简称为PUCCH)对量化的CSI信息(Channel quality indication,简称为CQI;Rank Indicator,简称为RI;Preceding Matrix Indicator,简称为PMI)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)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。此外,终端计算反馈CSI时,要基于传输模式的半 静态配置,根据传输模式的假设进行CSI计算和反馈。
CSI两种反馈类别:
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。
在相关技术中,CSI计算和反馈需要根据RRC信令进行半静态配置,这种方式极大地限制了CSI反馈和传输方式选取的灵活性,基站不能灵活地根据CSI动态地进行传输方式的调整,对信息传输的性能提升有较大的限制。针对相关技术中的上述问题,目前尚未存在有效的解决方案。

在一实施例中可以包括干扰测量参考信号(Interference Measurement Reference Signal,简称为IMR或IM),但需要说明的是,IMR导频也可以独立配置J0个干扰测量导频集合{RRC_IMR_Set0,…,RRC_IMR_SetJ0-1},而不包含在参考信号参数集合中。需要通过另外的高层信令来配置。
在一实施例中,所述的导频参数集合中的每个集合RRC_RS_Set,至少包括以下之一的参数和参数的取值:
RS类型:比如CSI-RS,SRS,DMRS,CRS等中的一个或者多个设置为测量信道状态信息的导频。
导频的时域特性,比如周期的Periodic,非周期的Aperiodic,半持续的,Semi-Persistent,如果是Periodic和Semi-Persistent,还需要包括配置导频传输的周期,偏置等子帧配置。
导频的频域特性,比如是宽带的,子带的。
导频的图样,比如所占的时域资源,频域资源的,序列,端口数目,相当于数据载波的功率比,所使用的正交覆盖码、频域密度等。
需要说明的是,上述导频资源参数是针对每个用户独立配置的,如果每个用户都占用一套导频资源,显然会导致导频开销的增加,为了节省导频开销,可以配置K>1套的导频资源,多个用户共享所述K套导频资源从而形成导频资源池(比如CSI-RS pool),基站动态地配置将导频资源池里的一套或者多套导频资源通过信令或者约定的方式,指示给用户,便于用户根据所指示的导频资源进行CSI测量。
在一实施例中,导频资源池也可以包括多于一个导频资源池。
把导频资源参数的内容总结如表1所示。

总结起来,CSI反馈相关参数集合可以包括如下表3所示的参数。

需要说明的是,上述CSI反馈相关的参数,也是针对每个用户进行配置的,在未来的无线通信技术中,可能会涉及到多层网络,每个网络又有多个基站,每个基站包括多个波束。从而会使得反馈的内容非常多,需要较多的资源来反馈这些参数信息。为了节省上报CSI的资源,也可以将CSI反馈相关参数配置成池子,叫CSI反馈池,所述CSI反馈池包括多个CSI反馈参数的配置,多个用户共享所述的CSI反馈池,至于哪个用户使用,由基站确定或者基站和用户通过协议约定的方式确定。
(1.2)通过物理层信令,或者Media Access Control control element(MAC CE)配置导频资源参数集合的索引以指示终端需要测量的导频资源信息,和/或配置CSI反馈参数集合索引以指示终端CSI反馈相关的信息。

(2)三层信令配置方式
基站通过(2.1),(2.2),(2.3)的方式配置导频相关参数集合和/或信道状态信息反馈相关参数集合。
(2.1)通过高层信令配置导频资源参数集合:RRC_RS_Set0,…,RRC_RS_SetM0-1
通过高层信令配置N0信道状态信息反馈相关参数集合:RRC_CSI_Set0,…,RRC_CSI_SetN0-1。
其中,导频资源参数集合和CSI反馈相关参数集合的内容和(1)中的两层信令结构的类似,这里不再重述。
(2.2)通过MAC CE配置导频资源参数子集,和/或CSI反馈相关参数子集。
其中,MAC CE的导频资源参数子集,导频资源参数子集的取值由导频资源参数集合RRC_RS_Set0,…,RRC_RS_SetM0-1确定,即RRC_RS_Set0,…,RRC_RS_SetM0-1中的M1个。可以记为MAC_RS_Set0,…,MAC_RS_SetM1-1.在MAC CE里可以只配置MAC_RS_Set0,…,MAC_RS_SetM1-1在RRC_RS_Set0,…,RRC_RS_SetM0-1中的索引,可以通过索引找到MAC_RS_Set0,…,MAC_RS_SetM1-1的参数配置信息。
如果是非周期的,MAC CE还需要包括所述M1个导频相关参数子集MAC_RS_Set0,…,MAC_RS_SetM1-1.的激活时间。如果是Semi persisitent的,MACCE还包括时还包括M1个导频相关参数子集MAC_RS_Set0,…,MAC_RS_SetM1-1.的激活或去激活的参数配置。
MAC CE的CSI反馈相关参数子集,CSI反馈相关参数子集的取值由CSI反馈相关参数集合RRC_CSI_Set0,…,RRC_CSI_SetN0-1确定,即RRC_CSI_Set0,…,RRC_CSI_SetN0-1中的N1个。可以记为MAC_CSI_Set0,…,MAC_CSI_SetN1-1。MAC CE可以只配置MAC_CSI_Set0,…,MAC_CSI_SetN1-1在RRC_CSI_Set0,…,RRC_CSI_SetN0-1的索引,通过索引来确定CSI反馈相关参数的集合。
如果是非周期的,MAC CE还需要包括所述N1个CSI反馈相关参数子集MAC_CSI_Set0,…,MAC_CSI_SetN1-1.的激活时间。如果是Semi persisitent的,MAC CE还包括N1个CSI反馈相关参数子集MAC_CSI_Set0,…,MAC_CSI_SetN1-1的激活或去激活的参数配置。

实施例八
本实施例给出了实施例七中信道信息反馈参数配置的示例性实施方式。主要是码本子 集限制CSR及其反馈开销的更细节的设计。如图5A所示,在RRC配置多个比特图,并在MAC CE或者DCI信令中选择其中的一个或者多个比特图。下面将根据比特图的形式,分成二个方式来描述CSR参数的配置。
方式一:RRC信令里配置的比特图是整个码本的比特图。
比如天线配置为N1行N2列,配置的码本第一维度过采样因子为O1,第二维度过采样因子为O2,那么第一预编码矩阵W1总共有Nb=N1*N2*O1*O2个beam,对这些beam进行排列,每个beam用一个比特表示,当bit表示0时为终端不可以选择的beam,为1时表示终端可以选择的beam。这就叫W1码本的bit图每个用Nb个比特来表示Nb个beam中的beam是否可以被使用。当然,也可以有第二维度预编码矩阵W2的比特图,以及其它码本的bit图,都是为了限制哪些码本可以使用,哪些码本终端不可以使用,具体的概念可以参考LTE/LTE A的协议。
在本实施例的方式一中,比特图都是包含整个码本的比特图,比如上述W1,需要Nb比特来表示比特图。
RRC配置CSR参数集合,集合中的每个元素为一张整个码本的比特图,如图5B所示,比如分别为整个码本的比特图1,整个码本的比特图2,整个码本的比特图3,…,整个码本的比特图N。
不同的比特图中比特的取值不同,可以达到在不同角度范围的码字精度不一样的目的,比如,在方向1上需要更高的进度,那么在方向1附近的所有beam对应的bit都取值为1,否则,可以在这个方向附近的几个beam中只选择其中的一个beam的比特取值为1。
在两层信令配置方式下,基站只需要直接在DCI中指示终端所使用的RRC信令配置的CSR比特图集合中的那个元素的索引就可以。
终端接收RRC配置的CSR比特图集合,并接收DCI信令里的CSR比特图集合索引,利用CSR比特图集合索引在RRC配置的CSR比特集合里找到基站配置的属于自己的CSR比特图的取值,从而可以知道哪些beam被限制了。
在三层信令的情况下,基站在MAC层中,需要通过MAC CE进一步配置CSR参数子集,其中CSR参数子集中包括了一个或者多个RRC配置的比特图集合中的元素的索引。并在DCI中选择MAC层中配置的CSR子集中元素的索引。
终端接收RRC配置的CSR比特图集合,并接收MAC CE配置的CSR参数子集,并接收DCI信令里的子CSR参数集合索引,利用子CSR参数集合索引在MAC CE配置的子CSR参数集合索引里找到基站配置的属于自己的子CSR参数集合的取值,并根据子CSR参数集合的取值在RRC配置的获取CSR比特图的取值,从而可以知道哪些beam被限制了。
方式二:RRC信令里配置的1个整个码本的CSR比特图,并配置N个取自总比特图的CSR比特图。
如图5C所示,RRC配置一张整个码本的CSR总比特图,并配置N个取自于总比特 图的子CSR比特图:比如Nb1比特的子CSR比特图1,Nb2比特的子CSR比特图2,…,NbN比特的子CSR比特图N,其中,Nb1,Nb2,…,NbN可以是不同的值,即每个子CSR比特图包含的比特数目不同,但也可以是相同的。
可以有多种从总CSR比特图中选择子CSR比特的方法,每种方法可以实现不同的功能。
方法1:实现不同的子CSR集合指示有不同过采样因子的码本的目的。
这种可以实现不同方向的过采样因子不同的目的,总比特图对应的码字为8倍过采样,子CSR比特图1从总的CSR比特图中每隔8个bit取一个值构成的子CSR比特图,那么就实现了1倍过采样的目的,子CSR比特图2从总的CSR比特图中每隔4个bit取一个值构成的子CSR比特图,那么就实现了2倍过采样的目的,子CSR比特图3从总的CSR比特图中每隔2个bit取一个值构成的子CSR比特图,那么就实现了4倍过采样的目的。这种子CSR比特图的选择可以针对1维码本的第一预编码矩阵W1,这时只限制过采样因子O1,也可以针对2维码本的第一预编码矩阵W1,这时过采样因子包括第一维度过采样因子O1和第一维度过采样因子O2,子CSR比特图可以通过从总的CSR比特图里选择不同子CSR比特图来达到限制O1和O2的目的。
方法2:连续地取Nk比特作为子CSR比特图。
可以将总比特图分成Nb/Nk等分,每一等分包括连续的Nkbit大小的子CSR比特图。
比如,Nk=8,那么将总比特图分成8等分,每一等分包括8比特的子CSR比特图。
RRC中配CSR参数集合,每个CSR参数集合中包括包括Nk比特的子CSR比特图。
在两层信令配置方式下,基站只需要直接在DCI中指示终端所使用的RRC信令配置的CSR比特图集合中的那个元素的索引就可以。
终端接收RRC配置的CSR比特图集合,并接收DCI信令里的CSR比特图集合索引,利用CSR比特图集合索引在RRC配置的CSR比特集合里找到基站配置的属于自己的CSR比特图的取值,从而可以知道哪些beam被限制了。
并且终端可以根据自身的信道状态信息,对DCI指示的CSR集合中的子CSR比特图进行扩展或重构或重新赋值,形成新的子CSR比特图。利用新的子CSR比特图进行beam/码字的选择。终端也可以反馈新的子CSR比特图。
在三层信令的情况下,基站在MAC层中,需要通过MAC CE进一步配置CSR参数子集,其中CSR参数子集中包括了一个或者多个RRC配置的比特图集合中的元素的索引。并在DCI中选择MAC层中配置的CSR子集中元素的索引。
终端接收RRC配置的CSR比特图集合,并接收MAC CE配置的CSR参数子集,并接收DCI信令里的子CSR参数集合索引,利用子CSR参数集合索引在MAC CE配置的子CSR参数集合索引里找到基站配置的属于自己的子CSR参数集合的取值,并根据子CSR参数集合的取值在RRC配置的获取子CSR比特图的取值,从而可以知道哪些beam被限制了。
同样地,并且终端可以根据自身的信道状态信息,对DCI指示的CSR集合中的子CSR比特图进行扩展或重构或重新赋值,形成新的子CSR比特图。利用新的子CSR比特图进行beam/码字的选择。终端也可以反馈新的子CSR比特图。
这里的CSR比特图或者子CSR比特图就是CSR参数集合里的元素,而CSR参数子集表示CSR参数集合的子集合,或者指向CSR参数集合的索引,或者索引的集合。
另外,终端和基站可以根据CSR限制达到减小反馈码字开销的目的。即比如第一预编码矩阵索引i1的开销,和/或者第二预编码就很索引i2的开销。其中开销的大小和如下参数有关:
CSR参数集合指示信息,
CSR参数子集指示信息,
CSR参数指示信息。
在LTE的版本13中,设计的码本由于包括两个维度的DFT矢量,码字数量一般比较多,这会增加反馈的开销,为了减小开销,将码本根据码本子集选择配置信令(Codebook Config)分成不同的子集合,不同码本子集配置信令(CodebookConfig)对应不同的码字。其中对于同一个i11和i12下,CodebookConfig=1时,i2码本只有co-phase相位选择的4个码字,而CodebookConfig>1时,i2包括co-phase相位选择和beam选择等16个码字。其中,i11和i12分别对应第一预编码矩阵的第一维度索引和第二维度索引。i2对应第二预编码矩阵索引。
但这需要RRC信令配置CodebookConfig的值,这里可以通过构造CSR参数集合中CSR比特图的内容,从而达到对码本进行码本类型选择的目的。比如CSR参数集合里的CSR比特图i限制的终端可以用的码字和CodebookConfig=i对应的码字相同i=1,2,3,4。从而通过配置CSR参数集合达到限制i2反馈开销的目的,比如在CSR比特图1中,只需要反馈2bit的cophasing,而在i=2,3,4的时候,需要反馈4bit的i2。
实施例九
本实施例给出了信道信息反馈参数配置的一种示例性实施方式,主要涉及到CSI上报资源的配置。
在本实施例中,设置为上报CSI的资源包括CSI上报的时域资源,比如在哪几个符号或者子帧上上报,和/或CSI上报的频域资源,比如在哪些子载波或者子载波组,子载波集合上上报CSI,和/或CSI上报的波束,比如在哪个或者几个波束上上报CSI,这里的波束主要是指终端的波束。为了达到CSI上报资源多个用户共享的目的,这里,将多个CSI上报资源形成一个CSI上报资源池(pool)。在CSI资源上报池里有K个CSI上报资源配置CSI_Config1,CSI_Config2,…,CSI_ConfigK。每个CSI上报资源配置中至少包括CSI上报的时域资源、CSI上报的频域资源、CSI上报的波束中的1个或者多个组合。
所述CSI上报资源可以应用于周期CSI上报,比如根据周期和子帧偏置,周期地在 某些子帧上报CSI,但每个子帧里的符号可以使用不同的波束。也可以应用于非周期CSI上报。
基站通过如下的显示信令指示的方式,或者根据双方的约定关系,或者信道是否互易等隐含的方式指示终端使用的CSI上报的资源。方法包括但不限于以下方式:
方式一:
基站通过高层信令配置CSI上报资源集合CSI_Config1,CSI_Config2,…,CSI_ConfigK,并在某个下行子帧通过高层或者物理层信令指示终端CSI上报资源集合的索引。
终端根据基站信令确定CSI上报资源集合,并根据基站发送的CSI上报资源集合的索引信令从CSI上报资源集合中选取CSI上报资源;
方式二:
基站通过高层信令配置CSI上报资源集合;
终端根据基站信令确定CSI上报资源集合,并自行从中选取CSI上报资源集合中CSI上报资源设置为CSI上报;
方式三:
基站和终端通过约定CSI上报时域资源集合和CSI上报的波束资源的关系,从而终端可以根据所述的关系确定设置为CSI上报的第一无线资源。
终端自行确定CSI上报的波束信息,并根据约CSI上报时域资源集合和CSI上报的波束资源的关系确定设置为CSI上报的时域资源。
这里约定的关系包括比如奇数子帧的CSI上报资源用波束1上报,偶数子帧的CSI上报资源用波束2上报。
这里,CSI上报的时域资源,也可以替换成CSI上报的频域资源,CSI上报的时域资源和CSI上报的频域资源。
方式四:
基站通过高层信令配置CSI上报时域资源集合,并通过高层或者物理层信令指示终端从CSI上报时域资源集合选取CSI上报的时域资源。基站和终端约定CSI上报的时域资源集合和波束资源的关系,设置为终端确定CSI上报的波束资源。
终端根据基站信令确定CSI上报时域资源集合,并根据基站信令从CSI上报时域资源集合中选取CSI上报的CSI上报时域资源,通过约定的CSI上报时域资源集合和波束资源的关系确定设置为CSI上报的波束信息;
这里约定的关系包括比如奇数子帧的CSI上报资源用波束1上报,偶数子帧的CSI上报资源用波束2上报。
这里,CSI上报的时域资源,也可以替换成CSI上报的频域资源,CSI上报的时域资源和CSI上报的频域资源。
方式五:
基站通过高层信令配置CSI上报的时域资源集合,约定CSI上报的时域资源和波束资源的关系或者关系集合,并在高层或者物理层信令中指示终端从所述关系或者关系集合中选择CSI上报资源。
终端根据基站信令确定CSI上报时域资源集合,以及CSI上报的时域资源和波束的关系或关系集合,并根据基站信令从上述集合中选取CSI上报的时域资源;
这里约定的关系包括比如奇数子帧的CSI上报资源用波束1上报,偶数子帧的CSI上报资源用波束2上报。
这里,CSI上报的时域资源,也可以替换成CSI上报的频域资源,CSI上报的时域资源和CSI上报的频域资源。
所说的关系集合是包括一个以上的关系,需要在MAC CE里进一步配置信令指示关系集合里的一个子集或关系集合的元素索引,并通过物理层信令进一步指示关系子集合索引。
终端需要根据物理层信令获得关系子集的索引,并通过之关系的索引在MAC CE接收到的子关系集合的关系或者子关系集合里面的索引去找高层信令配置的关系集合里的关系。
方式六:
基站通过高层信令配置CSI上报的波束资源集合,并通过高层或者物理层信令指示用户从所述的波束资源集合中选择CSI上报的波束资源,并和终端约定CSI上报的时域资源和波束资源的关系。
终端根据基站信令确定CSI上报的波束资源集合,并根据基站信令从波束资源集合中选取CSI上报的波束,通过约定的CSI上报的时域资源集合和波束资源的关系确定设置为CSI上报的时域资源;
这里约定的关系包括比如奇数子帧的CSI上报资源用波束1上报,偶数子帧的CSI上报资源用波束2上报。
这里,CSI上报的时域资源,也可以替换成CSI上报的频域资源,CSI上报的时域资源和CSI上报的频域资源。
方式七:
基站通过高层信令确定CSI上报的波束资源集合,以及约定CSI上报时域资源和波束资源的关系,或者关系集合,基站通过高层或者物理层信令指示终端从上述关系或者关系集合中选择CSI上报的时域资源。
终端根据基站信令确定CSI上报波束资源集合,以及CSI上报的时域资源和波束资源的关系或关系集合,并根据基站信令从CSI上报资源集合中选取CSI上报的时域资源。并根据CSI上报的时域资源和波束资源的关系或关系集合以及CSI上报的时域资源确定CSI上报的频域资源。
这里约定的关系包括比如奇数子帧的CSI上报资源用波束1上报,偶数子帧的CSI 上报资源用波束2上报。
这里,CSI上报的时域资源,也可以替换成CSI上报的频域资源,CSI上报的时域资源和CSI上报的频域资源。
需要说明的是,本实施例的方法,如果同个终端被配置了多个CSI上报资源,比如时域上的多个TTI,频域上的多个子载波集合,或者空域上的多个波束资源,那么在这些CSI上报的资源上,终端上报的内容可以是相同的,从而可以使得基站获得更鲁棒的CSI上报资源。
实施例十
本实施例给出了导频资源配置的示例性实施方式。主要是多个导频资源池的配置问题。
为了描述的简单,这里的导频资源池以CSI-RS导频资源池CSI-RS pool为例,其它的导频比如CRS,SRS,DMRS的导频资源池的方式类似。
为了多个用户共享几套导频,基站配置一个CSI-RS pool,这个CSI-RS pool中包括M套CSI-RS导频资源,每套CSI-RS导频资源包括导频的pattern,导频的端口数目,导频的时域特性,频域特性等。基站会指定一组用户共享这套导频资源池。并且通过信令显示指示的方式或者约定的关系或者绑定的关系指示用户使用了CSI-RS pool里的哪一个或者几个CSI-RS资源用来测量信道状态信息。
可选地,基站可以配置多于1套的CSI-RS pool,实现更加灵活的CSI-RS资源的配置。这里以N套CSI-RS pool为例,比如CSIRS_POOL1,…,CSIRS_POOLN。
基站需要显示地或隐式地指示用户需要测量的CSI-RS pool。终端根据基站显示的信令通知或者隐式的绑定的或约定的关系获得CSI-RS pool的信息,在这个CSI-RS pool上根据基站显示或者隐式的信令确定1个或者多个CSI-RS资源用户CSI的测量。
CSI-RS资源指示信息CRI,每个CRI的取值对应着一个CSI-RS资源,也隐含地对应着一个波束。因为基站配置的CSI-RS可能是通过一个波束进行预编码后发送的。
对于有N个CSI-RS pool的情况,每个资源池都有一个CRI与之对应对应/相关、绑定,或者有N个CRI,每个都和一个CSI-RS pool对应/相关、绑定。
其中,CSI-RS pool参数还包括时域参数,比如子帧索引、子帧偏置、时隙slot索引、符号索引、帧索引。这里的索引也可以是编号。
当CSI-RS是非周期配置的,或者通过物理层信令触发/激活的,那么终端将忽略所述的时域参数配置。
终端和基站分别通过如下方式反馈和接收CRI和CSI-RS pool。
方式一:显示信令的方式
终端反馈N个导频资源指示信息、N个导频资源指示信息对应的导频资源集合;
基站接收终端反馈的N个CRI、接收N个CRI对应的导频资源集合;
方式二:隐式的约定关系或者绑定关系
基站和终端约定上报CRI的资源和导频资源集合。其中上报CRI的资源包括上报CRI 的时域资源、频域资源、波束中的至少一个资源。
基站根据终端上报的CRI资源,从而确定导频资源集合,并根据在上报CRI的资源上携带的值获得CRI的值。
方式三:基站配置绑定关系
基站配置上报CRI的资源和导频资源集合的关系。其中上报CRI的资源包括上报CRI的时域资源、频域资源、波束中的至少一个资源。
基站根据终端上报的CRI资源,以及自身配置的CRI的资源和导频资源集合的关系确定导频资源集合,并根据上报CRI的资源携带的值获得CRI的值。
在确定导频资源集合后,终端需要进一步确定使用的导频资源集合中的导频资源和/或导频资源子集。其中导频资源子集包括一个后者多个导频资源,但一般少于导频资源集合中的导频资源个数。基站和终端通过如下方式之一配置或者接收导频资源/导频资源子集:
方式一:信令配置
基站通过高层信令配置导频资源集合,通过高层或者物理层信令配置当前用户对应的导频资源的索引或者索引集合;
终端接收基站配置的导频资源的索引或者索引集合,并根据所述的导频资源的索引或者索引集合在导频资源集合中选择导频资源或导频资源子集。
方式二:绑定关系或者约定关系
基站和终端约定的导频资源/导频资源子集信令所占资源和导频资源集合的关系或者绑定关系。其中导频资源/导频资源子集信令所占资源包括传输导频资源/导频资源子集的时域资源、频域资源、波束中的至少一个资源。
终端通过导频资源/导频资源子集信令所占资源确定导频资源/导频资源子集。
方式三:基站配置的绑定关系或者约定关系
基站配置导频资源/导频资源子集信令所占资源和导频资源集合的关系或者绑定关系。其中导频资源/导频资源子集信令所占资源包括传输导频资源/导频资源子集的时域资源、频域资源、波束中的至少一个资源。
终端接收基站配置的导频资源/导频资源子集信令所占资源和导频资源集合的关系或者绑定关系,终端通过导频资源/导频资源子集信令所占资源以及所属的关系确定导频资源/导频资源子集。
实施例十一
速率匹配相关方式。配置参数可以是零功率CSI-RS资源,也可以是非零功率CSI-RS资源,或者是PQI。以零功率CSI-RS资源的配置为例,传统的方式是通过比特图配置零功率CSI-RS,以通知终端哪些位置不收数据。本公开的方式是通过约定的方式,例如按从前到后的顺序进行零功率CSI-RS指示,例如16个状态的ZP CSI-RS资源,原来需要 16个比特的比特图,现在可以根据基站和终端的约定前4个状态设置为配置零功率CSI-RS,这样信令就可以减小到4个比特,或者中间的连续4个状态设置为配置零功率CSI-RS,或者后面的连续的4个状态设置为配置零功率CSI-RS,或者任意其它的约定的4个连续的状态设置为配置配置零功率CSI-RS,或者不设置为配置零功率CSI-RS。缺点是实际CSI-RS的配置就会有所限制。具体的约定方式可以扩展。
本公开的实施例还提供了一种存储介质。可选地,在本实施例中,上述存储介质可以被设置为存储设置为执行以下步骤的程序代码:
S1,终端确定导频资源参数和/或信道状态信息反馈参数的取值集合;
S2,终端根据取值集合确定与终端对应的导频资源参数和/或信道状态信息反馈参数的取值。
本公开的实施例还提供了一种存储介质。可选地,在本实施例中,上述存储介质可以被设置为存储设置为执行以下步骤的程序代码:
S1,基站配置导频资源参数和/或信道状态信息反馈参数的取值集合;
