技术领域
本申请实施例涉及通信技术领域，尤其涉及一种CSI(Channel State Information，信道状态信息)测量方法及装置。
背景技术
随着移动通信技术朝着高速、大数据业务量等方向发展的同时，下一代移动通信系统要求大容量和高质量的数据传输，MIMO(Multiple-Input Multiple-Output，多入多出)技术被认为是可实现未来高速数据传输的关键技术之一，在第四代(4G)及第五代(5G)的移动通信系统中有着广阔的应用前景。传统的集中式MIMO系统的多根发射天线均集中于基站(BS)端。与集中式MIMO不同，分布式MIMO系统的多根发射天线分布于不同的地理位置，其各对收发链路之间更加独立，具有大容量、低功耗、更好的覆盖、对人体的低电磁损害等优势，被认为是未来无线通信系统的备选方案之一。
在分布式MIMO的情况下，CoMP(Coordinated Multipoint Transmission，协同多点传输)被认为是一种解决小区间干扰问题并提升边缘用户吞吐量的有效方法。CoMP技术中多个相邻小区可以联合处理或协调边缘用户来避免干扰并提升边缘用户吞吐量。下行CoMP技术主要包括JT(Joint Transmission，联合传输)、协同调度和CS/CB(Coordinated Scheduling and Beamforming，波束赋形)和DPS/DPB(Dynamic Point Selection/Dynamic Point Blanking，动态点选择/关闭)，其中JT分为相干JT和非相干JT。为了实现这些CoMP调度，服务基站需要知道各站点到目标用户的下行信道条件。
在LTE(Long Term Evolution，长期演进)规范中，提供了一种参考信号，即CSI-RS(Channel State Information Reference Signal，信道状态信息参考信号)。终端通过对特定的CSI-RS的测量来估计信道的干扰状态，得到CSI-IM(Channel State Information Interference Measurement，信道状态信息干扰测量)，并通过PUCCH(Physical uplink control channel，物理上行控制信道)CSI-IM信息将上报给服务基站。为了配置终端接收和处理指定的CSI-RS，并提供所需的反馈信息，基站通过配置高层RRC(Radio resource control，无线资源控制)信令来指示终端。然而，作为CoMP技术中一种，JT是将多个小区同时调度为一个用户传输数据，这将导致不同的频域位置干扰情况不同。或者在5G中，不同的频域位置传输不同的数据类型，也导致不同的频域位置干扰情况不同。由于现有技术当中，CSI-IM和CSI速率匹配一般都是全带宽配置的，无法对带宽中特定频域位置干扰情况进行测量。

具体实施方式
下面结合附图，对本申请的实施例进行描述。
相关技术在进行CSI-IM进行测量时，一般是按照现有协议，通过服务小区的基站为服务小区的终端配置CSI Process(进程)，使终端根据基站配置的CSI Process进行CSI-IM。然而，服务小区为终端配置的CSI Process一般是基于整个信道带宽的测量。这样即便终端测量到信道带宽中有干扰信息，终端也无法确定该干扰信息具体是在信道带宽中的哪个频段。另外，信道带宽中一般是有些频段有干扰信息，而有些频段没有干扰信息，如果终端对整个带宽都进行CSI-IM，那么终端按照服务小区给终端配置的CSI Process进行测量，会造成资源的浪费。
示例性的，如图1所示，通过CoMP技术，终端同时与传输点TP1、传输点TP2进行通信。这样终端与TP1之间存在通信信道，并且终端与TP2之间也有通信信道，终端需要分别对两个通信信道的信道带宽进行CSI-IM，以分别获取两个信道带宽中的最优调度子带，使得TP1和TP2分别通过相应的最优子带分别与终端进行通信。然而，由于这两个通信信道之间会存在重叠的情况，会造成二者相互干扰，使得这两个通信信道中不同的子带受到的干扰程度情况也不一样，造成相关技术中终端对CSI-IM测量的测量结果可能会不准确；另外，相关技术中通过终端对全带宽的CSI-IM，也会导致导频的开销较大，造成资源浪费。
因此，为了解决相关技术中不能准确对信道带宽进行CSI-IM及在测量过程中资源浪费的问题，本申请实施例中提供了一种CSI测量方法及装置。其中，本申请实施例在对CSI进行测量过程，可以应用到终端与终端、终端与基站以及基站与基站之间等的通信过程中，本申请实施例不限于此。为了便于理解，本申请以终端与基站之间的通信为例进行说明。
第一网络设备和第二网络设备的解释说明。
网络设备，比如基站或其他类型传输点设备，当然不也限于上述两种设备，比如第二设备也可以是能够实现对其他终端进行配置操作的终端。
其中，基站可以是LTE系统或其演进系统中的演进型基站(Evolutional Node B，简称为eNB或e-NodeB)、宏基站、微基站(也称为“小基站”)、微微基站、接入站点(Access Point，简称为AP)或传输站点(Transmission Point，简称为TP)等，也可以是未来网络中的基站，如5G网络中的基站。
在本申请实施例中，终端也可称为用户设备(User Equipment，简称为UE)，或者可称之为Terminal、移动台(Mobile Station，简称为MS)、移动终端(Mobile Terminal)等，该终端可以经无线接入网(Radio Access Network，简称为RAN)与一个或多个核心网进行通信，例如，终端可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机等，例如，终端还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语音和/或数据。本申请实施例中的终端还可以是D2D(Device to Device，设备与设备)终端或者M2M(Machine to Machine，机器与机器)终端。
如图1所示，基站100、300基站同时与终端200进行通信，在对终端200的移动性 管理和通信过程中，通过终端200进行CSI-IM，并将基站100和/基站300报告测量结果，是辅助基站进行切换判决的重要方式。实施例中，以图1中对终端200与基站100之间信道带宽的CSI测量为例进行说明，对终端200与基站300之间的信道带宽可以采用同样的方式进行CSI测量。另外，终端还可以同时对基站100和基站300的信道带宽进行CSI测量。
为了让终端200进行CSI测量，基站100还向终端发送参考信号。例如，LTE规范中，提供了一种CSI参考信号，即CSI-RS，用于终端对CSI进行测量。
在需要终端200对信道带宽进行CSI测量时，基站100会确定信道带宽中子带的哪个频域需要测量。因此，基站100会生成CSI配置信息，该CSI配置信息包括第一频域指示信息，该CSI配置信息用于指示终端测量信道带宽中与第一频域指示信息相对应频域上的参考信号。
相关技术采用的CSI配置信息如下：服务基站可以为目标用户配置多个CSI进程，在每个CSI进程中会指示终端非零功率(Non-zero power，NZP)用于测量信道信息，同时还会指示干扰测量资源(Interference measurement resource,IMR)，用于测量干扰。此外，对于每个CSI进程对应的用户上报内容和/上报方式也会相应的在配置中指定。
具体的CSI配置信息，可以包括，CSI进程信息，包括CSI进程标识csi-ProcessId，测量信道信息的配置标识csi-RS-ConfigNZPId，测量干扰信息的配置标识csi-IM-ConfigId。因此，本申请实施例中为了实现终端200对信道带宽的准确测量，在已有的CSI配置信息中加入第一频域指示信息。
为了使终端200根据基站100发送的CSI配置信息对相应频域上的参考信号进行CSI测量，需要对信道带宽进行划分。在本申请提供的实施例中，可以有两种方式对信道带宽进行划分，第一种信道带宽划分方式是基站100和终端200按照预先设定的方式进行划分，第二种划分方式中，基站100可以定义信道带宽划分的方式，将该划分方式包含在CSI配置信息中发送给终端200，终端200可以根据基站100发送的CSI配置信息进行信道划分。
在第一种信道带宽划分方式中，终端200和基站100可以根据预先确定的方式对信道带宽进行划分，将信道带宽划分为多个资源块。
需要说明的是，本申请实施例中，将信道带宽划分为多个资源块，每个资源块可以是1个RB，还可以是2个RB，或者是多个RB。每个资源块所包含的资源应当小于信道带宽。划分后的资源块之间可以有部分资源重叠，或者各个资源块的资源不重叠。资源块(Resource Block，RB)是现有LTE技术的资源单元(资源粒度)。在5G或者后续协议中，可以不按照RB定义资源单元。资源单元或者资源粒度可以按照其他的方式规定，在此不做限制。示例性的，如果信道带宽为100个RB，如果将信道带宽以2个RB为粒度进行划分，那么可以将信道带宽划分为50个资源块，每个资源块为2个RB。
其中，第一种信道带宽划分方式为终端200和基站100预先协商的，基站100可以不向终端再次确定划分规则。
在第二种信道带宽划分方式中，基站100可以将信道带宽的划分方式包含在CSI配置信息中，终端200根据基站100发送的CSI配置信息，对信道带宽进行划分。
具体的，基站100向终端发送的CSI配置信息中包含第一频域指示信息，终端200根据第一频域指示信息中的信道划分信息对信道带宽进行划分。
在将信道带宽划分为多个资源块之后，终端200根据基站100发送的CSI配置信息对参考信号进行测量。需要说明的是，该参考信号可以是基站100发送的，还可以是基站300发送的，或者是其它基站、传输点等发送的参考信号。
终端200对参考信号进行测量过程中，根据CSI配置信息，不需要对整个信道带宽进行CSI测量，可以对第一频域指示信息中对应的频域进行测量。
在终端200进行CSI测量时，可以有两种方式对划分为多个资源块的信道带宽进行测量。
在第一种测量方式中，信道带宽中划分的多个资源块中，将各个资源块分别对应一个频域测量标识，该频域测量标识可以分为第一测量标识和第二测量标识，终端200对第一测量标识对应的资源块进行测量，对第二测量标识对应的资源块不进行测量。示例性的，如果信道带宽为100个RB，如果以2个RB为粒度对信道带宽进行划分，划分为50个资源块，每个资源块为2个RB。那么CSI配置信息中可以包含50个比特，对50个资源块分别进行标识，例如，测量标识的bit信息为1或者0，终端200将测量标识为1的资源块进行测量，将测量标识为0的资源块不进行测量。这样终端200根据测量资源块的测量标识进行相应测量，可以准确的对信道带宽进行CSI测量。
示例性的，第一种测量方式可以采用bit mapping的形式，在利用上述实施例中的方式将信道带宽划分为多个资源块时，每个资源块的粒度可以是如下所示：
①在以1个RB为粒度进行信道带宽测量时，第一频域指示信息指示的bit mapping的bit个数是系统带宽的RB数，即
Figure PCTCN2017103925-appb-000001
表示信道带宽的RB数。
②在以2个RB为粒度进行信道带宽测量时，第一频域指示信息指示的bit mapping的bit个数是系统带宽的RB数的一半，即
Figure PCTCN2017103925-appb-000002
③在以现有的RBG(Resource Block Group，资源块组)的大小P个RB为粒度进行信道带宽测量时，第一频域指示信息指示的bit mapping的bit个数是
Figure PCTCN2017103925-appb-000003
其中，P大于或等于2，且为整数。如表1所示：
表1

④以现有的CSI测量的Subband Size(子带大小)大小K为粒度进行信道带宽测量时，第一频域指示信息指示的bit mapping的bit个数是
Figure PCTCN2017103925-appb-000005
其中，K为正整数。如表2所示。
表2
Figure PCTCN2017103925-appb-000006
在第二种测量方式中，CSI配置信息中的第一频域指示信息还可以包括待测量资源块的信息标识，该信息标识包括待测量资源块的频域位置。终端200可以根据待测量资源块的信息标识的指示，测量相应频域位置上的资源块。
示例性的，可以通过下述方式测量相应频域位置上的资源块：
方式1：
将所有的RBG被分为P个子集，P为RBG的大小。每个RBG子集p(0≤p＜P)包含从RBG p开始，间隔为P的所有RBG。分配给某个终端的RB资源必须来自于同一个子集。
第一个域包含

比特，用于指定所选的RBG子集，即p的值。
第二个域包含1比特(shift bit)，用于指定子集内的资源是否偏移，1表示偏移，0表示不偏移。
第三个域包含一个bitmap，bitmap的每一比特对应所选RBG子集中的一个RB(注意：不是RBG)。最高位表示子集中的第一个RB，最低位表示子集中的最后一个RB，依此类推。如果某个RB分配给了某个终端，则bitmap中对应比特置为1；否则置为0。bitmap的大小，即bitmap包含的比特数
Figure PCTCN2017103925-appb-000008
为
Figure PCTCN2017103925-appb-000009
一个选定的RBG子集中的RB起始于该子集中的最小RB号+偏移量Δshift(p)，并对应bitmap中的最高位。该偏移量以RB的数量表示，并且是发生在选定的RBG子集内的偏移。如果第二个域为0，则RBG子集p的偏移Δshift(p)＝0；如果第二个域为1，则RBG子集p的偏移

且bitmap中的最低比特位调整为对应RBG子集中的最后一个RB。

Figure PCTCN2017103925-appb-000013
对应的RB可通过如下公式计算：
Figure PCTCN2017103925-appb-000014
上述的RB可以是虚拟资源块(VRB)，也可以是物理资源块(PRB)。因此频域指示信息可以指示VRB的位置，然后VRB再映射为PRB。或者也可以直接指示PRB的位置，在此不做限制。
方式2：
在频域指示信息中，分配给终端的资源为一段连续的RB，其RB可以是集中式(localized)，也可以是分布式的(distributed)。
首先频域指示域中有一个比特用于指示是使用集中式RB(比如该比特为0)还是使用分布式RB(比如该比特为1)。
对于集中式资源分配由一个资源指示值RIV来表示。通过这个值，可以推导出分配给终端的起始RB(RBstart)以及连续分配的RB的长度(LCRBs)。计算公式如下：

终端收到一个RIV后计算RBstart和LCRBs的方式与上述类似，这里就不做介绍了。
上述的RB可以是虚拟资源块(VRB)，也可以是物理资源块(PRB)。因此频域指示信息可以指示VRB的位置，然后VRB再映射为PRB。或者也可以直接指示PRB的位置，在此不做限制。
具体的频域指示信息中待测量信息块的信息标识，可以采用现有协议中的资源指示方法，也可以采用其他的指示方法，在此不做限定。其中，该实施例中的终端可以以图1中终端200为例进行说明。
另外，终端200通过RRC或者物理层信令获取基站100发送的CSI配置信息。
具体的频域指示信息可以是针对CSI测量资源进行配置，也可以是针对CQI(Channel Quality Indicator，信道质量信息)上报进行配置。如果是针对CSI测量资源配置，则指示该参考信号所占的资源仅位于频域指示信息所指示的频域位置，UE仅需要测量该频域位置上的参考信号即可。如果是针对CQI上报进行配置，则指示UE上报的CQI是基于仅测量该频域指示信息所指示的频域位置上的参考信号得到的CSI。
具体的可以按照，如下信令域进行配置：
针对CSI Process中的干扰测量(CSI-IM)资源配置频域指示信息
基站针对CSI Process中的干扰测量(CSI-IM)资源配置频域指示信息，告知UE针对该资源测量的干扰仅适用于所指示的频域位置。当UE接收到该信令后，UE针对该资源测量的干扰仅考虑对所在频域位置的影响。
上报的时候可以是针对不同的干扰测量资源配置的频域指示信息上报该频域的CSI信息，也可以是上报整个测量带宽的平均的CSI信息。
具体的频域指示信息通过frequencyConfig域进行指示，如下：
Figure PCTCN2017103925-appb-000050
Figure PCTCN2017103925-appb-000051
针对该CSI-RS-configNZPId中的CSI-RS资源配置频域指示信息。
基站针对CSI-RS-configNZPId中的CSI-RS资源配置频域指示信息，指示UE针对该资源进行测量并且仅适用于频域指示信息所指示的频域位置。
具体的RRC信令通知(如新增frequencyConfig)，如下所示：

Figure PCTCN2017103925-appb-000053
针对CQI上报配置频域指示信息。
基站针对CQI上报配置频域指示信息，指示UE该上报的CQI是基于对频域指示信息所指示的频域位置上的参考信号进行测量得到的CSI。
具体的RRC信令通知(如新增frequencyConfig)，如下所示：
Figure PCTCN2017103925-appb-000054
终端200对第一频域指示信息对应频域上的参考信号测量，得到CSI，该CSI可以包括信道带宽中测量的各个资源块分别对应的测量结果，还可以是将测量的各个资源块中的测量结果按照预设方式进行处理，将处理后的结果作为CSI。其中，该预设方式可以是将 测量各个资源块的测量结果进行求平均或取最大值等方式，来确定CSI。终端200可以以测量报告的形式将CSI上报给基站100。
相关技术中，一般也是终端基于全带宽的速率匹配，而不能对信道带宽中特定频域位置上的信号进行速率匹配。导致相关技术中终端得到的速率匹配结果可能不准确，并且耗费资源。因此，根据需要，为了可以实现对信道带宽中特定频域位置上对应的数据进行速率匹配，在本申请提供的又一实施例中，还提供了一种速率匹配方法，用于进行速率匹配，仍旧以图1为例进行说明。其中，本申请实施例速率匹配的过程，可以应用到终端与终端、终端与基站以及基站与基站之间等的通信过程中，本申请实施例不限于此。为了便于理解，本申请以终端与基站之间的通信为例进行说明。
结合图1所示，基站100向终端发送速率配置信息，该速率匹配信息包括第二频域指示信息。其中，速率配置信息用于指示终端200进行速率匹配；第二频域指示信息，用于指示终端200对第二频域指示信息相对应的频域上的参考信号的资源位置上接收的数据进行速率匹配。
其中，这里的第二频域指示信息，与上述实施例中的第一频域指示信息可以不同，上述实施例中的第一频域指示信息主要用于指示终端200进行CSI测量的频域位置，这里的第二频域指示信息主要指示终端200进行速率匹配的频域位置，可以称为第二频域指示信息。
终端200接收基站100发送的速率配置信息，并根据该速率配置信息，对第二频域指示信息相对应的频域上的参考信号的资源位置上接收的数据进行速率匹配。其中，参考信号可以由基站100发送的，还可以由其它基站或传输点等发送。
在终端200根据速率配置信息进行速率匹配的过程中，还需要对信道带宽进行划分，将信道带宽划分为多个资源块，具体资源块的划分方式，可以采用上述实施例的信道划分方式，这里不再赘述。
速率匹配方案下的频域指示信息的具体指示方法如下：
基站100在PDSCH-RE-MappingQCL-Config域中的csi-RS-ConfigZPId-r11中的信息中配置频域指示信息。即基站100针对ZP CSI-RS资源配置频域指示信息，指示UE针对该ZP CSI-RS资源进行速率匹配时仅考虑其所在频段即可。
当UE接收到该信令后，UE根据ZP CSI-RS所在的资源位置对数据进行速率匹配时仅考虑其所在频域即可，而不需要考虑全带宽进行速率匹配。
具体RRC信令(如frequencyConfigList)如下所示：
Figure PCTCN2017103925-appb-000055
Figure PCTCN2017103925-appb-000056
上述的速率匹配既可以是数据映射到该资源后进行打孔，也可以是数据不在该资源上进行映射，包括但不限于上述情形。
针对物理层信令通知的方法：
在DCI(Downlink Control Information，下行控制信息)中增加CSI测量的频域指示信息和/或速率匹配频域信息。
CSI测量的频域指示信息举例如下所示：
-CSI frequency information field–4or 5bits
如果有多个CSI process配置需指示CSI-process ID
如果有多个CSI-IM配置需指示CSI-IM ID
如果有多个NZP CSI-RS配置需指示NZP CSI-RS ID
该域用于指示CSI测量的参考信号的频域位置信息或者用于指示CSI上报的频域位置信息。同时基站可以针对不同的测量资源标识配置频域指示信息，测量资源标识可以为CSI-process ID或者CSI-IM ID或者NZP CSI-RS ID，或者其他的测量资源，在此不做限制。
频域指示一般采用粒度相对较大的方式指示，这样可以减小信令的开销，比如subband(子带)粒度等。
速率匹配的频域指示信息举例如下所示：
-rata matching frequency information field–2or 3bits
该域用于指示速率匹配的参考信号的频域位置信息。
速率匹配的参考信号可以是ZP CSI-RS，或者其他用于指示UE进行速率匹配的参考信号，在此不做限制。
下面以速率匹配信号为ZP CSI-RS为例，基站100可以预先配置多个ZP CSI-RS ID，当给UE发送数据时的ZP CSI-RS与之前配置的RRC信令中的不一致时，可以通过物理层信令通知UE，仅通知ZP CSI-RS ID即可。即基站可以针对不同的ZP CSI-RS ID配置频域指示信息。
需要说明的是，本申请实施例中的上述配置方法包括但不限于上述方案。
速率配置信息中的第二频域指示信息，包括：信道带宽的多个资源块中每个资源块分别对应一个速率匹配标识。该速率匹配标识可以分为第一速率匹配标识和第二速率匹配标识。终端200通过获取信道带宽中多个资源块中每个资源块分别对应的速率匹配标识，来确定信道带宽中频域匹配标识为第一速率匹配标识的参考信号的资源位置。这里可以采用上述实施例中bit mapping的方式，将每个资源块分别对应一个速率匹配标识，以便终端200根据该速率匹配标识，对相应资源块上的数据进行速率匹配。
另外，第二频域指示信息还可以包括：待速率匹配资源块的信息标识，该信息标识中包括频域位置，终端200在进行速率匹配时，确定与频域位置相对应的资源块上参考信号的资源位置，并根据该资源位置对数据进行速率匹配。

在本申请提供的又一实施例中，由于信道的多径衰落和多普勒特性等，会导致不同的频域位置(或者子带)信道矩阵不同。在基站进行协作非相干JT传输时，因为不同的频域位置(或者子带)信道不同，在选择预编码矩阵传输时也会导致不同的频域位置预编码矩阵不同，因此在不同频域位置(或者子带)上的流间(或者层间或者码字间)干扰不同。
相关技术中，干扰测量是全带宽进行平均得到的干扰结果，这种情况下，干扰测量是不准确的。
针对协作传输下，为了让终端在CSI测量的时候可以得到准确的流间(或者层间或者码字间)干扰下的信道状态信息，需要考虑频域受限的干扰测量或者是子带干扰测量。
本申请实施例提供的干扰测量方法，可以包括以下几种具体实现方式：
方式一，如图10所示，在本申请提供的一实施例中，本申请该实施例提供的干扰测量方法，可以包括以下步骤：
步骤S1001，终端接收来自基站的第一信息，其中，第一信息包括CSI干扰测量的频域信息，该CSI干扰测量的频域信息与CSI信道测量的频域信息具有对应关系。
该信道测量的频域信息可以是与信道测量相关的信息的频域信息，其中，与信道测量相关的信息，可以为例如下述中的至少一种：RI(Rank Indication，秩指示)、PMI(Precoding Matrix Indicator，预编码矩阵指示)、CQI和CRI(CSI-RS Resource Indicator，信道状态信息参考信号资源指示)等信道测量信息。
该干扰测量的频域信息可以是指与干扰测量相关的信息的频域信息，其中，与干扰测量相关的信息，可以为例如下述中的至少一种：RI(Rank Indication，秩指示)、PMI(Precoding Matrix Indicator，预编码矩阵指示)、CQI和CRI(CSI-RS Resource Indicator，信道状态信息参考信号资源指示)等干扰测量的信息。
第一信息可以是CSI配置信息。例如在LTE系统中，该CSI配置信息可以包括：CSI上报配置信息、参考信号配置信息中的至少一种。在NR(5G系统)中，该CSI配置信息可以包括：参考信号集合(RS setting)配置信息、CSI上报集合(CSI reporting setting)配置信息和CSI测量集合(CSI measurement setting)配置信息中的至少一种。
基于此，作为举例，CSI干扰测量的频域信息可以由上述信息、或任何具有类似功能的信息的至少一种进行承载。
而CSI干扰测量的频域信息的具体表现形式，可以为：
CSI上报配置信息或CSI上报集合配置信息中的CSI干扰上报模式，其中，CSI干扰上报模式指示了CSI干扰测量的频域信息；参考信号配置信息中的CSI干扰测量参考信号的频域信息；参考信号集合配置信息中的CSI干扰测量参考信号的频域信息；CSI测量集合配置信息中的频域信息。
以CSI干扰上报模式为例，比如基站可以配置的CSI干扰上报模式包括：子带CSI干 扰上报模式、部分带宽CSI干扰上报模式或全带CSI干扰上报模式等。基站向终端发送配置的CSI干扰上报模式，终端在接收到该CSI干扰上报模式后，可以根据该CSI干扰上报模式，确定CSI干扰测量的频域信息，进而进行CSI干扰测量。
具体的，由于CSI干扰上报模式指示了CSI干扰测量的频域信息，所以终端可以根据该CSI干扰上报模式，确定CSI干扰测量的频域信息。
作为另外一个例子，也可以采用CSI干扰测量参考信号的频域信息，来指示干扰测量的频域信息。
具体如何指示，可以参考之前实施例的指示方法。
进一步的，CSI干扰上报模式又可以包括周期性、非周期性、半持续性等。以针对周期性的CSI干扰上报模式为例(以表3为例)，基站可以配置终端接收CQI和PMI的干扰上报类型，比如：模式1-0为全带CQI(wideband CQI)，不上报PMI；模式1-1为全带CQI,全带PMI；模式2-0为子带CQI，不上报PMI；模式2-1为子带CQI，子带PMI。其他上报类型不限。另外针对RI也可以配置上报类型，比如全带RI或者子带RI等。
终端在接收到该周期性的CSI干扰上报模式后，可以根据该CSI干扰上报模式，确定CSI干扰测量的频域信息，进而进行CSI干扰测量。
Figure PCTCN2017103925-appb-000057
表4
当然，还可以采用上述2-4的表现形式，来实现CSI干扰测量的频域信息的指示。其中，在上述实施方式中，CSI干扰测量的频域信息与CSI信道测量的频域信息可以具有对应关系。上述对应关系，可以是1种或多种信道测量的频域信息对应1种或多种干扰测量的频域信息，在多种频域信息的情况下，可以取其频域带宽的集合或者取其最大/最小者。其中，信道测量的对象可以是RI、PMI、CQI和CRI等，干扰测量的对象可以是上述信道测量对象中的一种或多种。
从基站配置的角度，基站可以通过一定的对应关系，对CSI干扰测量的频域信息与CSI信道测量的频域信息进行配置。比如，信道测量可以为子带上报的信息或者全带上报的信息，如果信道测量的频域信息为子带上报的信息，干扰测量也采用子带上报的信息进行测量。如果信息测量采用全带上报的信息进行测量，那么干扰测量也采用全带上报的信息进行干扰测量。在这种方式中，干扰测量的频域信息与信道测量的频域信息相同。值得说明的是，频域信息可以指代频域(对应一定的带宽)。
当然，干扰测量的频域信息与信道测量的频域信息也可以不相同。可以有以下几种情况：
1)干扰测量的频域大于信道测量的频域；2)干扰测量的频域与信道测量的频域部分 重叠。这种情况的干扰测量的频域与信道测量的频域有部分相同，有部分不相同。
3)干扰测量的频域与信道测量的频域完全不重叠。这种情况的干扰测量的频域与信道测量的频域完全不相同。
另外，在第一信息为CSI配置信息时，CSI配置信息可以包括CSI干扰测量的频域信息和/或CSI信道测量的频域信息，CSI信道测量的频域信息和/或CSI干扰测量的频域信息为全带宽的子集。
其中，全带宽的子集包括N个资源单位，其中，N大于或者等于1，且小于全带宽的总资源单位数量。该资源单位可以是资源块(Resource Block，RB)。资源块(Resource Block，RB)是现有LTE技术的资源单元(资源粒度)。在5G或者后续协议中，可以不按照RB定义资源单元。资源单元或者资源粒度可以按照其他的方式规定，比如与帧结构的参数有关(比如子载波间隔或者循环移位的长度等)在此不做限制。
全带宽的子集还可以表现为子带，或者说全带宽的子集包括M个子带，其中，M大于或者等于1，且小于全带宽的总的子带数量。
具体的子带可以有如下所示几种方式：

步骤S1002，终端根据CSI干扰测量的频域信息，对该CSI干扰测量的频域信息对应频域上的CSI干扰测量资源进行测量。
具体的，参考信号可以包括：信道测量参考信号和/或干扰测量参考信号。其中，信道测量参考信号用于终端的信道测量，干扰测量参考信号用于终端的干扰测量。在CSI测量过程中，终端可以根据信道测量的频域信息进行信道测量，根据干扰测量的频域信息进行干扰测量。
在本申请实施例中，终端对对应频域上的CSI干扰测量资源进行测量指的是，在该频域上对干扰测量参考信号进行测量。
据此，终端可以得到CSI干扰测量的结果。进一步的，终端还可以根据信道测量的频域信息进行信道测量，以得到CSI信道测量的结果，并根据上述CSI信道测量和CSI干扰测量的测量结果，综合得到CSI。
进一步的，干扰测量参考信号可以包括：NZP CSI-RS(Non-Zero Power Channel State Information-Reference Signal，非零功率信道状态信息参考信号)和ZP CSI-RS(Zero Power Channel State Information-Reference Signal，零功率信道状态信息参考信号)。
从基站配置的角度，CSI干扰测量的频域信息与CSI信道测量的频域信息具有对应关系，该对应关系可以预先定义或配置，该定义或配置对于基站和终端两侧均需要知悉。针对不同的CSI-RS资源，关于上述对应关系，本申请实施例又提供了多种可选的实现方式，比如：
1)在有NZP CSI-RS资源和ZP CSI-RS资源时，仅确定NZP CSI-RS资源进行干扰测量时的频域信息，根据ZP CSI-RS资源进行干扰测量时仍然采用全带宽测量的方式。即，对NZP CSI-RS资源进行干扰测量时，采用上述对应关系。
由于在通过ZP CSI-RS资源进行干扰测量时仅进行干扰功率的测量，会造成测量结果不是很准确，并且由于不同的频域可能差别不会很大，所以可以通过全带宽平均的方式提高准确性。而通过NZP CSI-RS资源进行干扰测量时，可以具体得到信道矩阵信息或者进一步可以得到预编码矩阵信息，因此可以进行准确的测量。而且不同的频域可能会使得到的测量结果差别比较大，因此全带宽平均的方式会导致干扰测量不准确，进而针对NZP CSI-RS资源测量干扰的频域信息可以按照信道测量的频域信息确定，这样不但降低信令开销，又可以提高CSI测量的准确性。
2)在没有NZP CSI-RS资源而有ZP CSI-RS资源时，确定根据ZP CSI-RS资源进行干扰测量时的频域信息。即，对ZP CSI-RS资源进行干扰测量时，采用上述对应关系。
示例性的，比如干扰测量资源中仅包含ZP CSI-RS资源。
在CS/CB场景中，在具体的数据调度时，邻区可能会在不同的频段会采用不同的预编码/波束进行数据传输，因为邻区不同的数据传输的预编码/波束，对终端造成的干扰情况不同，例如不同的预编码/波束会使得信号能量在不同的位置强度不同，进而不同的频域信息上的干扰程度不同。因此可以在用ZP CSI-RS资源进行干扰测量时的频域信息可以按照信道测量的频域信息确定，对应的得到该频域信息上的信道状态信息，提高信道状态信息测量的准确性。
3)在有NZP CSI-RS资源和ZP CSI-RS资源时，不但确定根据NZP CSI-RS资源进行 干扰测量时的频域信息，还确定根据ZP CSI-RS资源进行干扰测量时的频域信息。即，对NZP CSI-RS资源和ZP CSI-RS资源进行干扰测量时，都采用上述对应关系。
当NZP CSI-RS资源上不同频域信息对应不同干扰情况，而且ZP CSI-RS资源上不同频域信息也会对应不同干扰情况时，可以考虑在用NZP CSI-RS资源进行干扰测量时的频域信息可以按照信道测量的频域信息确定，用ZP CSI-RS资源进行干扰测量时的频域信息也可以按照信道测量的频域信息确定，对应的得到该频域信息上的信道状态信息，提高信道状态信息测量的准确性。
4)在有NZP CSI-RS资源和ZP CSI-RS资源时，仅确定根据ZP CSI-RS资源进行干扰测量时的频域信息，根据NZP CSI-RS资源进行干扰测量时仍然采用全带宽测量的方式。
再进一步的，其中NZP CSI-RS资源可以是Class A的CSI-RS资源或者Class B的CSI-RS资源。
方式二，如图11所示，作为基站侧的执行流程，在本申请提供的又一实施例中，本申请该实施例提供的干扰测量方法，可以包括以下步骤：
步骤S2001，基站确定CSI干扰测量的频域信息，CSI干扰测量的频域信息与CSI信道测量的频域信息具有对应关系。
其中，在上述实施方式中，CSI干扰测量的频域信息与CSI信道测量的频域信息可以具有对应关系。上述对应关系，可以是1种或多种信道测量的频域信息对应1种或多种干扰测量的频域信息，在多种频域信息的情况下，可以取其频域带宽的集合或者取其最大/最小者。其中，信道测量的对象可以是RI、PMI、CQI和CRI等，干扰测量的对象可以是上述信道测量对象中的一种或多种。
从基站配置的角度，基站可以通过一定的对应关系，对CSI干扰测量的频域信息与CSI信道测量的频域信息进行配置。比如，信道测量可以为子带上报的信息或者全带上报的信息，如果信道测量的频域信息为子带上报的信息，干扰测量也采用子带上报的信息进行测量。如果信息测量采用全带上报的信息进行测量，那么干扰测量也采用全带上报的信息进行干扰测量。在这种方式中，干扰测量的频域信息与信道测量的频域信息相同。值得说明的是，频域信息可以指代频域(对应一定的带宽)。
当然，干扰测量的频域信息与信道测量的频域信息也可以不相同。可以有以下几种情况：
1)干扰测量的频域大于信道测量的频域；2)干扰测量的频域与信道测量的频域部分重叠。这种情况的干扰测量的频域与信道测量的频域有部分相同，有部分不相同。
3)干扰测量的频域与信道测量的频域完全不重叠。这种情况的干扰测量的频域与信道测量的频域完全不相同。
步骤S2002，基站向终端发送第一信息，所述CSI干扰测量的频域信息与CSI信道测量的频域信息具有对应关系。
另外，在第一信息为CSI配置信息时，CSI配置信息可以包括CSI干扰测量的频域信息和/或CSI信道测量的频域信息，CSI信道测量的频域信息和/或CSI干扰测量的频域信息为全带宽的子集。
其中，全带宽的子集包括N个资源单位，其中，N大于或者等于1，且小于全带宽的总资源单位数量。该资源单位可以是资源块(Resource Block，RB)。资源块(Resource Block， RB)是现有LTE技术的资源单元(资源粒度)。在5G或者后续协议中，可以不按照RB定义资源单元。资源单元或者资源粒度可以按照其他的方式规定，比如与帧结构的参数有关(比如子载波间隔或者循环移位的长度等)在此不做限制。
全带宽的子集还可以表现为子带，或者说全带宽的子集包括M个子带，其中，M大于或者等于1，且小于全带宽的总的子带数量。
具体的子带可以有如下所示几种方式：

具体的，参考信号可以包括：信道测量参考信号和/或干扰测量参考信号。其中，信道测量参考信号用于终端的信道测量，干扰测量参考信号用于终端的干扰测量。在CSI测量过程中，终端可以根据信道测量的频域信息进行信道测量，根据干扰测量的频域信息进行干扰测量。
进一步的，干扰测量参考信号可以包括：NZP CSI-RS(Non-Zero Power Channel State Information-Reference Signal，非零功率信道状态信息参考信号)和ZP CSI-RS(Zero Power Channel State Information-Reference Signal，零功率信道状态信息参考信号)。
从基站配置的角度，CSI干扰测量的频域信息与CSI信道测量的频域信息具有对应关系，该对应关系可以预先定义或配置，该定义或配置对于基站和终端两侧均需要知悉。针对不同的CSI-RS资源，关于上述对应关系，本申请实施例又提供了多种可选的实现方式，比如：

由于在通过ZP CSI-RS资源进行干扰测量时仅进行干扰功率的测量，会造成测量结果不是很准确，并且由于不同的频域可能差别不会很大，所以可以通过全带宽平均的方式提高准确性。而通过NZP CSI-RS资源进行干扰测量时，可以具体得到信道矩阵信息或者进一步可以得到预编码矩阵信息，因此可以进行准确的测量。而且不同的频域可能会使得到的测量结果差别比较大，因此全带宽平均的方式会导致干扰测量不准确，进而针对NZP CSI-RS资源测量干扰的频域信息可以按照信道测量的频域信息确定，这样不但降低信令开销，又可以提高CSI测量的准确性。

当NZP CSI-RS资源上不同频域信息对应不同干扰情况，而且ZP CSI-RS资源上不同频域信息也会对应不同干扰情况时，可以考虑在用NZP CSI-RS资源进行干扰测量时的频域信息可以按照信道测量的频域信息确定，用ZP CSI-RS资源进行干扰测量时的频域信息也可以按照信道测量的频域信息确定，对应的得到该频域信息上的信道状态信息，提高信道状态信息测量的准确性。
4)在有NZP CSI-RS资源和ZP CSI-RS资源时，仅确定根据ZP CSI-RS资源进行干扰测量时的频域信息，根据NZP CSI-RS资源进行干扰测量时仍然采用全带宽测量的方式。
再进一步的，其中NZP CSI-RS资源可以是Class A的CSI-RS资源或者Class B的CSI-RS资源。
需要说明的是，本申请实施例中，基站可以根据信道测量的频域信息确定干扰测量的频域信息，还可以同时确定信道测量的频域信息和干扰测量的频域信息，本申请实施例不限于此。
方式三，如图12所示，在本申请提供的又一实施例中，该实施例提供的干扰测量方 法，可以包括以下步骤：
步骤S3001，终端接收来自基站的第二信息，第二信息包括CSI信道测量的频域信息，CSI干扰测量的频域信息CSI信道测量的频域信息具有对应关系。
步骤S3002，终端根据CSI信道测量的频域信息，确定CSI干扰测量的频域信息，并对CSI干扰测量的频域信息对应频域上的CSI干扰测量资源进行干扰测量。
该信道测量的频域信息可以是与信道测量相关的信息的频域信息，其中，与信道测量相关的信息，可以为例如下述中的至少一种：RI(Rank Indication，秩指示)、PMI(Precoding Matrix Indicator，预编码矩阵指示)、CQI和CRI(CSI-RS Resource Indicator，信道状态信息参考信号资源指示)等信道测量信息。
该干扰测量的频域信息可以是指与干扰测量相关的信息的频域信息，其中，与干扰测量相关的信息，可以为例如下述中的至少一种：RI(Rank Indication，秩指示)、PMI(Precoding Matrix Indicator，预编码矩阵指示)、CQI和CRI(CSI-RS Resource Indicator，信道状态信息参考信号资源指示)等干扰测量的信息。
其中，在上述实施方式中，CSI干扰测量的频域信息与CSI信道测量的频域信息可以具有对应关系。上述对应关系，可以是1种或多种信道测量的频域信息对应1种或多种干扰测量的频域信息，在多种频域信息的情况下，可以取其频域带宽的集合或者取其最大/最小者。其中，信道测量的对象可以是RI、PMI、CQI和CRI等，干扰测量的对象可以是上述信道测量对象中的一种或多种。
从基站配置的角度，基站可以通过一定的对应关系，对CSI干扰测量的频域信息与CSI信道测量的频域信息进行配置。比如，信道测量可以为子带上报的信息或者全带上报的信息，如果信道测量的频域信息为子带上报的信息，干扰测量也采用子带上报的信息进行测量。如果信息测量采用全带上报的信息进行测量，那么干扰测量也采用全带上报的信息进行干扰测量。在这种方式中，干扰测量的频域信息与信道测量的频域信息相同。值得说明的是，频域信息可以指代频域(对应一定的带宽)。
当然，干扰测量的频域信息与信道测量的频域信息也可以不相同。可以有以下几种情况：

具体的，由于CSI上报模式指示了CSI信道测量的频域信息，终端可以根据CSI干扰测量信息的频域信息与CSI信道测量的频域信息具有对应关系，因此终端可以确定干扰测量的频域信息。
作为另外一个例子，也可以采用CSI信道测量参考信号的频域信息，具体如何指示，可以参考之前实施例的指示方法。
进一步的，CSI上报模式又可以包括周期性、非周期性、半持续性等。以针对周期性的CSI上报模式为例(以表9为例)，基站可以配置终端接收CQI和PMI的上报类型，比如：模式1-0为全带CQI(wideband CQI)，不上报PMI；模式1-1为全带CQI,全带PMI；模式2-0为子带CQI，不上报PMI；模式2-1为子带CQI，子带PMI。其他上报类型不限。另外针对RI也可以配置上报类型，比如全带RI或者子带RI等。
终端在接收到该周期性的CSI干扰上报模式后，可以根据该CSI上报模式，确定CSI信道测量的频域信息，进而进行CSI干扰测量。

需要说明的是，在本申请提供的实施例中，一个CSI测量集合可以有一个或者多个CSI 上报集合；一个或者多个CSI上报集合是从至少一个参考信号集合中选择产生的。一个或者多个CSI资源是从至少一个CSI-RS资源集合中选择产生的。具体的与频域信息相关的指示信息可以放在上述3个配置信息中的至少一项中。
本申请上述实施例提供的干扰测量方法，可以适用于协作场景，比如下行CoMP主要包括JT(Joint Transmission，联合传输)、协同调度和CS/CB(Coordinated Scheduling and Beamforming，波束赋形)和DPS/DPB(Dynamic Point Selection/Dynamic Point Blanking，动态点选择/关闭)，其中JT分为相干JT和非相干JT。
如图14所示，在JT场景下基站400与基站500在进行联合传输时，基站400与基站500之间的资源有三种情况，即二者资源完全重叠、部分重叠和不重叠。如果二者资源有重叠，则会导致流间(或者层间或者码字间)比如为了测量两个基站资源完成重叠的情况下的CSI，则可以配置子带的CSI上报模式，终端在进行信道测量的时候确定子带的频域信息，同时在进行干扰测量的时候也采用信道测量相同的子带的频域信息，这样可以测得重叠情况下的流间(或者层间或者码字间)干扰情况。此时干扰测量资源与信道测量资源完全相同，具体的，在干扰测量资源分为NZP CSI-RS和ZP CSI-RS时，本申请实施例采用NZP CSI-RS测量流间(或者层间或者码字间)干扰，ZP CSI-RS测量基站400和基站500之外的基站带来的干扰，而且可以让NZP CSI-RS测量干扰时的资源信息与信道测量的资源信息相同，而ZP CSI-RS测量干扰时可以是全带宽的测量。
在两个基站资源部分重叠的情况下，因为重叠的部分是有流间干扰，而不重叠的地方是没有流间(或者层间或者码字间)干扰的。因此为了测量准确的CSI，可以配置终端在非重叠的部分的信道测量时不考虑流间(或者层间或者码字间)干扰，在重叠的部分的信道测量时考虑流间(或者层间或者码字间)干扰，具体的可以在测量基站1的数据传输时的CSI可以配置终端在信道测量子带1，不考虑流间(或者层间或者码字间)干扰测量；在信道测量子带2上，考虑基站2在测量子带2上的流间(或者层间或者码字间)干扰测量。(此时干扰测量资源与信道测量资源的部分资源相同)具体的，干扰测量资源分为NZP CSI-RS和ZP CSI-RS时，此时可以考虑用NZP CSI-RS测量流间(或者层间或者码字间)干扰，ZP CSI-RS测量基站1和基站2之外的基站带来的干扰，而且可以让NZP CSI-RS测量干扰时的资源信息与信道测量的资源信息相同，而ZP CSI-RS测量干扰时可以是全带宽的测量。比如在测量子带1时，仅配置ZP CSI-RS测量干扰，而且是全带宽测量。在测量子带2时，可以配置NZP CSI-RS测量子带2上的流间(或者层间或者码字间)干扰,配置ZP CSI-RS测量干扰时可以是全带宽的测量。
在两个基站资源完全不重叠的情况下，因为不重叠的地方是没有流间干扰的。因此为了测量准确的CSI，可以配置终端在非重叠的部分的信道测量时不考虑流间干扰，具体的可以在测量基站1的数据传输时的CSI可以配置终端在信道测量子带1进行信道测量，而干扰测量可以是全带宽测量。(此时干扰测量资源与信道测量资源的部分资源相同)具体的，配置信道测量的频域信息为子带1，而配置ZP CSI-RS测量干扰时可以是全带宽的测量。
其中NZP CSI-RS资源可以是Class A的CSI-RS资源或者Class B的CSI-RS资源。
本申请上述实施例提供的干扰测量方法，可以适用于CS/CB场景中，在本申请提供的实施例中，如图15所示，基站1与基站2在进行CS/CB传输时，因为邻基站在进行不同 的波束方向传输时会导致不同的干扰情况，比如图中波束2的干扰大于波束3的干扰大于波束4的干扰。而邻基站在数据调度是在不同的频域资源调度不同的用户是会采用不同的预编码或波束进行传输。因此为了测量准确的CSI信息，可以配置子带的CSI上报模式，终端在进行信道测量的时候确定子带的频域信息，同时在进行干扰测量的时候也采用信道测量相同的子带的频域信息，这样可以测得对应频段下的干扰情况。(此时干扰测量资源与信道测量资源完全相同)具体的，干扰测量资源分为NZP CSI-RS和ZP CSI-RS时，此时可以考虑用NZP CSI-RS测量同频段定向波束的干扰，ZP CSI-RS测量基站1和基站2之外的基站带来的干扰，而且可以让NZP CSI-RS测量干扰时的资源信息与信道测量的资源信息相同，而ZP CSI-RS测量干扰时可以是全带宽的测量。另外也如果基站确定给终端传输数据时邻区的波束方向信息，可以配置干扰测量的频域信息为该波束方向的数据或者信号的频域信息。比如TP2用频段1进行波束2的传输，用频段2进行波束3的传输，用频段3进行波束4的传输。基站配置终端进行信道测量的频段为频段X，而如果干扰波束为波束2，则可以配置干扰测量的频段为频段1；如果干扰波束为波束3，则可以配置干扰测量的频段为频段2；如果干扰波束为波束4，则可以配置干扰测量的频段为频段3。而信道测量的频段X可以与干扰测量的频段相同或者不同。不同时可以通过配置频域偏移信息实现，比如如果信道测量为频段1，干扰测量为频段1，则可以配置干扰测量的频域偏移信息为0；如果信道测量为频段1，干扰测量为频段2，则可以配置干扰测量的频域偏移信息为1；如果信道测量为频段1，干扰测量为频段3，则可以配置干扰测量的频域偏移信息为2。终端可以通过信道测量的频域信息以及频域偏移信息确定干扰测量的频域信息。(新增)此时的干扰测量资源可以是NZP CSI-RS资源也可以是ZP CSI-RS资源，其中NZP CSI-RS资源可以是Class A的CSI-RS资源或者Class B的CSI-RS资源。
