Description

信道状态信息处理方法及其装置
本申请要求于2017年5月5日提交中国专利局、申请号为201710314139.7、申请名称为“信道状态信息处理方法及其装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信领域，尤其涉及一种信道状态信息处理方法及其装置。
背景技术
在多基站协作多点传输场景中，网络侧需要配置多个信道和干扰测量资源，终端设备侧需要测量并反馈一种或多种干扰情况下的信道状态信息(Channel State Information，CSI)，以使网络侧根据多种CSI合理确定多基站协作多点传输的传输方案，相应的链路自适应配置，以及调度策略。
图1所示为三基站协作多点传输的场景示意图，传输接收点(Transmission Reception Point，TRP)1、TRP 2和TRP 3是处于协作集合内的协作传输基站，TRP 4是处于协作集合外的干扰基站。对于TRP 1，存在如下可能的干扰组合：
干扰测量假设条件1：协作集合内TRP 2的干扰和协作集合外TRP 4的干扰；
干扰测量假设条件2：协作集合内TRP 3的干扰和协作集合外TRP 4的干扰；
干扰测量假设条件3：协作集合内TRP 2和TRP 3的干扰，以及协作集合外TRP 4的干扰；
干扰测量假设条件4：协作集合外TRP 4的干扰；
网络侧为确定多基站协作传输方案，相应的链路自适应配置以及调度策略，需要终端设备测量反馈上述一个或多个干扰测量假设条件下的CSI。
在长期演进(Long Term Evolution，LTE)中，网络侧配置CSI进程，终端设备根据配置的CSI进程测量上报。为测量不同干扰情况下的CSI，需要配置多个CSI进程。一个CSI进程与一个干扰测量假设条件相对应，在协作基站数量增加的情况下，干扰测量假设条件也会增加，从而导致测量上报所需的CSI进程增加，系统不具有可扩展性。一个CSI进程包括一个用于信道测量的非零功率信道状态信息参考信号(Non-Zero Power Channel State Information-Reference Signal，NZP CSI-RS)资源和一个用于干扰测量的零功率信道状态信息参考信号(Zero Power Channel State Information-Reference Signal，ZP CSI-RS)资源，在干扰测量假设条件增加的情况下，需要配置更多的ZP CSI-RS资源，从而导致大量的下行传输资源被占用。

本发明实施例可以应用于无线通信系统，无线通信系统通常由小区组成，每个小区包含一个基站(Base Station，BS)，基站向多个终端设备提供通信服务。其中基站包含基带单元(Baseband Unit，BBU)和远端射频单元(Remote Radio Unit，RRU)。BBU和RRU可以放置在不同的地方，例如：RRU拉远，放置于离高话务量的开阔区域，BBU放置于中心机房。BBU和RRU也可以放置在同一机房。BBU和RRU也可以为一个机架下的不同部件。
需要说明的是，本发明实施例提及的无线通信系统包括但不限于：窄带物联网系统(Narrow Band-Internet of Things，NB-IoT)、全球移动通信系统(Global System for Mobile Communications，GSM)、增强型数据速率GSM演进系统(Enhanced Data rate for GSM Evolution，EDGE)、宽带码分多址系统(Wideband Code Division Multiple Access，WCDMA)、码分多址2000系统(Code Division Multiple Access，CDMA2000)、时分同步码分多址系统(Time Division-Synchronization Code Division Multiple Access，TD-SCDMA)，长期演进系统(Long Term Evolution，LTE)、NR系统以及未来移动通信系统。
本发明实施例中，所述基站是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置。所述基站可以包括各种形式的宏基站，微基站(也称为小站)，中继站，接入点，TRP等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如，在LTE系统中，称为演进的节点B(evolved NodeB，eNB或者eNodeB),在第三代(3rd Generation，3G)系统中，称为节点B(Node B，NB)等。为方便描述，本发明所有实施例中，上述为终端设备提供无线通信功能的装置统称为网络设备。
本发明实施例中所涉及到的终端设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。所述终端设备也可以称为移动台(Mobile Station，MS)、终端(Terminal)，还可以包括用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能手机(smart phone)、无线数据卡、个人数字助理(Personal Digital Assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handset)、膝上型电脑(laptop computer)、机器类型通信(Machine Type Communication，MTC)终端等。为方便描述，本发明所有实施例中，上面提到的设备统称为终端设备。
本发明实施例可以应用于图1所示的三基站协作多点传输的场景示意图，TRP 1、TRP 2和TRP 3是处于协作集合内的协作传输基站，TRP 4是处于协作集合外的干扰基站。对于协作集合内的某个TRP，存在协作集合内的其它TRP对该TRP的干扰、协作集合外的TRP对该TRP的干扰的至少一种。例如，对于TRP 1，存在四种可能的干扰测量假设条件：第 一种，协作集合内TRP 2的干扰和协作集合外TRP 4的干扰；第二种，协作集合内TRP 3的干扰和协作集合外TRP 4的干扰；第三种，协作集合内TRP 2和TRP 3的干扰，以及协作集合外TRP 4的干扰；第四种，协作集合外TRP 4的干扰。针对存在多种干扰测量假设条件的情况，网络侧为确定多基站协作传输方案，相应的链路自适应配置以及调度策略，需要终端设备测量反馈一个或多个干扰测量假设条件下的CSI。
在LTE中，网络侧针对一个干扰测量假设条件配置一个CSI进程，在协作基站数量增加的情况下，干扰测量假设条件也会增加，从而导致所需配置的CSI进程数量增加，系统不具有可扩展性。一个CSI进程包括一个用于信道测量的非零功率信道状态信息参考信号NZP CSI-RS资源和一个用于干扰测量的ZP CSI-RS资源，在干扰测量假设条件增加的情况下，需要配置更多的ZP CSI-RS资源，从而导致大量的下行传输资源被占用。
鉴于此，本发明实施例提供一种信道状态信息处理方法及其装置，在协作基站增加的情况下，可以使系统具有可扩展性，可以避免占用过多的下行传输资源。
第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)新空口(New Radio，NR)定义了新的CSI测量上报架构，包括CSI上报配置信息(CSI Reporting Setting)，资源配置信息(Resource Setting)和测量配置信息(Measurement Setting)。针对一个终端设备，配置一个Measurement Setting，该Measurement Setting包括至少一个CSI Reporting Setting、至少一个Resource Setting和至少一个关联关系(Link)。一个Link指示一个CSI Reporting Setting与一个Resource Setting的关联，同时指示该Resource Setting用于信道测量或干扰测量。
图2为基于该CSI测量上报架构的一种测量配置指示方案的示例图，以CSI Reporting Setting 0为例，通过两个Link分别连接到Resource Setting 0和Resource Setting 1。其中，Resource Setting 0包含K个信道状态信息干扰测量(Channel State Information-Interference Measurement，CSI-IM)资源，用作干扰测量。Resource Setting 1包括1个信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)资源，用作信道测量。在该方案中，通过从K个CSI-IM资源中选取I个CSI-IM资源作为一种干扰测量假设条件，计算CSI时，以Resource Setting 1中的CSI-RS资源测得的作为信号部分，以Resource Setting 0中的CSI-IM资源测得的作为干扰部分。若需测量多种干扰测量假设条件，则网络侧需要指示多个干扰测量假设条件，需要多次指示，每次指示若干个CSI-IM资源，从而存在大量指示开销。
请参见图3，为现有的一种测量上报方法的示例图，网络侧配置了三个Resource Setting，Resource Setting 0对应信道测量，Resource Setting 1对应干扰测量1，Resource Setting 2对应干扰测量2。图3存在四种干扰测量假设条件(Hypothesis H1—H4)。终端设备根据某种准则选择一个或多个干扰测量假设条件所对应的CSI报告，以及相应的干扰测量假设条件的指示信息进行上报，干扰测量假设条件的指示信息包括一个或多个Resource Setting的序号。例如，为上报H1、H3对应的CSI报告，需要上报H1对应的Resource Setting序号1和2，上报H3对应的Resource Setting序号2。在协作基站数量增加的情况下，Resource Setting个数也会增加，干扰测量测量假设条件的数量和每个干扰测量假设条件所包括的Resource Setting个数也会增加，从而导致终端设备的上报开销增加。
鉴于在协作基站数量增加的情况下，网络侧指示干扰测量假设条件存在增加指示开销的弊端，终端侧上报存在增加上报开销的弊端，本发明实施例提供的信道状态信息处理方法及其装置，网络侧可以指示终端侧选择性测量、上报，并且测量、上报均是针对CSI-RS资源集合，进而可以节省指示开销和上报开销。
下面将结合附图4-附图9对本发明实施例提供的信道状态信息处理方法进行详细介绍。
请参见图4，图4是本发明实施例提供的一种信道状态信息处理方法的通信示意图，从网络设备与终端设备交互的角度进行介绍，该方法包括但不限于如下步骤：
步骤S201：网络设备配置至少一个CSI上报配置信息和所述至少一个CSI上报配置信息对应的资源配置信息；
具体地，网络设备针对其覆盖范围内的任意一个终端设备可以配置至少一个CSI上报配置信息(CSI Reporting Setting)和所述至少一个CSI上报配置信息对应的资源配置信息(Resource Setting)。一个所述CSI上报配置信息对应至少两个资源配置信息。其中，所述至少一个CSI上报配置信息对应的资源配置信息为一个集合，该集合包括每个CSI上报配置信息对应的至少两个资源配置信息，即所述网络设备可针对所述至少一个CSI上报配置信息中的每个CSI上报配置信息关联配置至少两个资源配置信息，即所述每个CSI上报配置信息对应至少两个资源配置信息。本发明实施例中至少两个资源配置信息以两个资源配置信息为例进行介绍，三个及三个以上的情况可类推。
一个所述CSI上报配置信息对应的所述至少两个资源配置信息中的一个所述资源配置信息用于干扰测量，包括CSI-RS资源集合(CSI-RS Resource Set)，具体包括至少一个CSI-RS资源集合；所述至少两个资源配置信息中的一个所述资源配置信息用于信道测量，包括NZP CSI-RS资源，具体包括至少一个NZP CSI-RS资源。其中，一个CSI-RS Resource Set对应至少一个干扰测量假设条件，CSI-RS Resource Set包括NZP CSI-RS资源、ZP CSI-RS资源中的至少一个。例如，一个CSI-RS Resource Set对应一个干扰测量假设条件，CSI-RS Resource Set#1包括NZP CSI-RS资源B和ZP CSI-RS资源D，那么CSI-RS Resource Set#1对应于一个干扰测量假设条件。
例如，CSI Reporting Setting 0关联配置Resource Setting 0和Resource Setting 1，Resource Setting 0用于信道测量，包括至少一个NZP CSI-RS资源；Resource Setting 1用于干扰测量，包括至少一个CSI-RS Resource Set。
一个CSI-RS资源集合对应至少一个CSI报告，一个CSI报告包括信道测量结果和干扰测量结果。在用于信道测量的资源配置信息包括一个NZP CSI-RS资源的情况下，一个CSI-RS资源集合对应一个CSI报告；在用于信道测量的资源配置信息包括两个或两个以上NZP CSI-RS资源的情况下，一个CSI-RS资源集合对应两个或两个以上CSI报告。
一个CSI上报配置信息对应至少两个资源配置信息，用于干扰测量的资源配置信息对应至少一个CSI-RS资源集合，进而可以推出一个CSI上报配置信息对应至少一个CSI-RS资源集合，进一步推出所述至少一个CSI上报配置信息对应至少一个CSI-RS资源集合。在本发明所有实施例中，令所述至少一个CSI上报配置信息对应的所有CSI-RS资源集合的数量为M，即所述至少一个CSI上报配置信息对应M个CSI-RS资源集合，M为正整数，M≥1， M的具体数值不做限定。
所述CSI上报配置信息包括CSI报告的配置信息。CSI报告的配置信息可以用于指示终端设备上报CSI报告的内容。CSI报告的内容可以包括信道质量指示(Channel Quality Indicator，CQI)、预编码矩阵指示(Precoding Matrix Indicator，PMI)、秩指示(Rank Indication，RI)、信道状态信息参考信号资源指示(Channel State Information-Reference Signal Resource Indicator，CRI)等参数中的至少一个。CSI报告的配置信息还可以指示终端设备上报时域特性、上报频域特性等。
所述网络设备可配置所述至少一个CSI上报配置信息对应的关联指示信息，一个所述CSI上报配置信息对应至少两个关联指示信息(Link)。所述至少一个CSI上报配置信息对应的关联指示信息是一个集合，该集合包括每个CSI上报配置信息对应的至少两个关联指示信息，即所述网络设备可针对所述每个CSI上报配置信息配置至少两个关联指示信息，所述至少两个关联指示信息中的一个所述关联指示信息指示一个所述CSI上报配置信息的标识和一个所述资源配置信息的标识，以及指示该资源配置信息用于信道测量；所述至少两个关联指示信息中的一个所述关联指示信息指示一个所述CSI上报配置信息的标识和一个所述资源配置信息的标识，以及指示该资源配置信息用于干扰测量。本发明实施例中至少两个关联指示信息以两个关联指示信息为例进行介绍，三个及三个以上的情况可类推。例如，针对CSI Reporting Setting 0配置Link 1和Link 2，Link 1指示CSI Reporting Setting的标识为0，Resource Setting的标识为0，并指示Resource Setting 0用于信道测量；Link 2指示CSI Reporting Setting的标识为0，Resource Setting的标识为1，并指示Resource Setting 1用于干扰测量。
所述网络设备可在无线资源控制(Radio Resource Control，RRC)信令中配置所述至少一个CSI上报配置信息和所述至少一个CSI上报配置信息对应的资源配置信息。所述网络设备可在RRC信令中配置所述至少一个CSI上报配置信息、所述至少一个CSI上报配置信息对应的资源配置信息以及所述至少一个CSI上报配置信息对应的关联指示信息。
基于图1所示的场景示意图，针对TRP 1分配NZP CSI-RS resource(A)，针对TRP 2分配NZP CSI-RS resource(B)，针对TRP 3分配NZP CSI-RS resource(C)，针对TRP 1、TRP 2、TRP 3分配ZP CSI-RS resource(D)，可参见图5所示的基于图1的CSI-RS资源分配示例表。其中，NZP CSI-RS resource可以用于干扰测量，也可以用于信道测量。ZP CSI-RS resource(D)可以用于干扰测量。根据图5所示的CSI-RS资源分配示例表，针对TRP 1可能存在的四种干扰测量假设条件可表示为：
干扰测量假设条件1：NZP CSI-RS resource(B)+ZP CSI-RS resource(D)；
干扰测量假设条件2：NZP CSI-RS resource(C)+ZP CSI-RS resource(D)；
干扰测量假设条件3：NZP CSI-RS resource(B)+NZP CSI-RS resource(C)+ZP CSI-RS resource(D)；
干扰测量假设条件3：ZP CSI-RS resource(D)。
在一个干扰测量假设条件对应于一个CSI-RS Resource Set的情况下，那么上述四种干扰测量假设条件可表示为四个CSI-RS Resource Set，这四个CSI-RS Resource Set可参见图6所示的一种CSI-RS资源集合示例图，可表示为：
CSI-RS Resource Set#1包括NZP CSI-RS resource(B)和ZP CSI-RS resource(D)；
CSI-RS Resource Set#2包括NZP CSI-RS resource(C)和ZP CSI-RS resource(D)；
CSI-RS Resource Set#3包括NZP CSI-RS resource B、NZP CSI-RS resource C和ZP CSI-RS resource(D)；
CSI-RS Resource Set#4包括ZP CSI-RS resource(D)。
由上述四个CSI-RS Resource Set可知，两个CSI-RS Resource Set可以包括相同的NZP CSI-RS resource，也可以包括相同的ZP CSI-RS resource，还可以包括相同的NZP CSI-RS resource和ZP CSI-RS resource，进而可推出，多个CSI-RS Resource Set之间可共享相同的CSI-RS resource，进而可以克服LTE中占用大量下行传输资源以及CSI进程无法共享测量资源和测量结果的弊端，进而可以节省下行传输资源，可以提高测量资源和测量结果的共享程度。
请参见图7，是本发明实施例提供的一种配置示例图，基于图1所示的场景示意图，网络设备配置CSI Reporting Setting 0，并针对CSI Reporting Setting 0关联配置Resource Setting 0和Resource Setting 1，Link 1和Link 2。Link 1指示CSI Reporting Setting 0与Resource Setting 0之间的关联，并指示Resource Setting 0用于信道测量；Link 2指示CSI Reporting Setting 0与Resource Setting 1之间的关联，并指示Resource Setting 1用于信道测量。其中，Resource Setting 0包括NZP CSI-RS resource(A)，Resource Setting 1包括上述四个CSI-RS Resource Set。
请参见图8，是本发明实施例提供的另一种配置示例图，网络设备配置CSI Reporting Setting 0，并针对CSI Reporting Setting 0关联配置Resource Setting 0和Resource Setting 1，Link 1和Link 2。Link 1指示CSI Reporting Setting 0与Resource Setting 0之间的关联，并指示Resource Setting 0用于信道测量；Link 2指示CSI Reporting Setting 0与Resource Setting 1之间的关联，并指示Resource Setting 1用于信道测量。其中，Resource Setting 0包括NZP CSI-RS resource(A)和NZP CSI-RS resource(B)，Resource Setting 1包括如下三个CSI-RS Resource Set：
CSI-RS Resource Set#1包括NZP CSI-RS resource(C)和ZP CSI-RS resource(D)；
CSI-RS Resource Set#2包括NZP CSI-RS resource(A)和ZP CSI-RS resource(D)；
CSI-RS Resource Set#3包括ZP CSI-RS resource(D)。
需要说明的是，图7、图8以一个CSI Reporting Setting为例进行介绍，对于存在两个或两个以上CSI Reporting Setting的情况，可根据图7、图8进行类推。图7是以Resource Setting 0只包括一个NZP CSI-RS resource(A)为例，图8是以Resource Setting 0只包括两个NZP CSI-RS resource为例，对于用于信道测量的资源配置信息包括两个以上的NZP CSI-RS资源的情况，可根据图8进行扩展。
在用于信道测量的资源配置信息包括的NZP CSI-RS资源的数量大于1的情况下，所述网络设备还可配置用于信道测量的NZP CSI-RS资源与用于干扰测量的CSI-RS资源集合之间的对应关系。例如，图8中，网络设备配置了如下对应关系：
对应关系1：NZP CSI-RS resource(A)与CSI-RS Resource Set#1之间；
对应关系2：NZP CSI-RS resource(A)与CSI-RS Resource Set#3之间；
对应关系3：NZP CSI-RS resource(B)与CSI-RS Resource Set#1之间；
对应关系4：NZP CSI-RS resource(B)与CSI-RS Resource Set#2之间；
对应关系5：NZP CSI-RS resource(B)与CSI-RS Resource Set#3之间。
上述对应关系1—5用于指示图8中用于信道测量的资源配置信息0与用于干扰测量的资源配置信息1之间的关系，若还存在资源配置信息0与用于干扰测量的资源配置信息2之间的关系，则可将上述五种对应关系称为第一对应关系，将资源配置信息0中的NZP CSI-RS资源与资源配置信息2中的CSI-RS资源集合之间的对应关系称为第二对应关系。
可选地，所述网络设备可在RRC信令中配置用于信道测量的NZP CSI-RS资源与用于干扰测量的CSI-RS资源集合之间的对应关系。该RRC信令可与配置所述至少一个CSI上报配置信息的RRC信令相同或不相同。
可选地，所述网络设备在动态信令中配置用于信道测量的NZP CSI-RS资源与用于干扰测量的CSI-RS资源集合之间的对应关系。所述动态信令可以是媒体接入控制控制元素(Media Access Control-Control Element，MAC-CE)，或其它层二信令。所述动态信令还可以是下行控制信息(Downlink Control Information，DCI)。
通过上述配置，在协作基站数量增加的情况下，干扰测量假设条件也会增加，此时网络设备只需增加CSI-RS Resource Set的个数，无需增加CSI Reporting Setting或Resource Setting的数量，可以使系统具有可扩展性。
可选地，所述网络设备还可以在所述至少一个CSI上报配置信息中对所述终端设备是否周期上报进行配置，例如，所述网络设备配置所述终端设备周期性(periodic)上报，或配置所述终端设备非周期(non-periodic)上报，或配置所述终端设备半持续性(semi-persistent)上报。
可选地，所述网络设备还可以在资源配置信息中配置CSI-RS资源周期性发送，或配置CSI-RS资源非周期性发送，或配置CSI-RS资源半持续性发送。CSI-RS资源可为NZP CSI-RS资源或ZP CSI-RS资源。

若所述网络设备配置了用于信道测量的NZP CSI-RS资源与用于干扰测量的CSI-RS资源集合之间的对应关系，则所述网络设备还向所述终端设备发送用于信道测量的NZP CSI-RS资源与用于干扰测量的CSI-RS资源集合之间的对应关系。可以是通过RRC信令发送，也可以是通过所述动态信令发送。
步骤S203：所述终端设备接收所述网络设备发送的所述至少一个CSI上报配置信息和所述至少一个CSI上报配置信息对应的资源配置信息；
具体地，所述终端设备可通过RRC信令来接收所述至少一个CSI上报配置信息和所述至少一个CSI上报配置信息对应的资源配置信息，也可通过RRC信令来接收所述至少一个CSI上报配置信息对应的关联指示信息。所述终端设备在接收到上述配置信息时，可对上述配置信息进行存储。
若所述网络设备发送了用于信道测量的NZP CSI-RS资源与用于干扰测量的CSI-RS资源集合之间的对应关系，则所述终端设备还接收用于信道测量的NZP CSI-RS资源与用于干扰测量的CSI-RS资源集合之间的对应关系。
步骤S204：所述终端设备根据所述至少一个CSI上报配置信息对应的资源配置信息进行测量；
具体地，所述终端设备根据所述至少一个CSI上报配置信息对应的用于信道测量的资源配置信息进行测量。例如，图7中，所述终端设备可根据NZP CSI-RS resource(A)进行测量，可以得到一个信道测量结果，该信道测量结果可以用于计算CQI、RI、PMI、CRI等参数中的至少一个。

在一种可能实现的方式中，所述终端设备可根据所述至少一个CSI上报配置信息对应的M个CSI-RS资源集合进行测量，换言之，所述终端设备根据所述网络设备配置的所有CSI-RS资源集合进行测量。
例如，图7中，CSI Reporting Setting 0对应的Resource setting 0包括1个用于信道测量的NZP CSI-RS Resource(A)，Resource Setting 1包括4个CSI-RS Resource Set，每个CSI-RS Resource Set包括2个用于干扰测量的NZP CSI-RS Resource(B,C)和1个用于干扰测量的ZP CSI-RS Resource(D)中的至少一个，所述终端设备可根据这一个用于信道测量的NZP CSI-RS Resource(A)和这4个CSI-RS Resource Set进行测量，可以得到4个CSI报告，即所述终端设备针对一个用于信道测量的NZP CSI-RS Resource和一个用于干扰测量的CSI-RS Resource Set进行测量得到一个CSI报告。
再例如，图8中，CSI Reporting Setting 0对应的Resource setting 0包括2个用于信道测量的NZP CSI-RS Resource(A，B)，Resource Setting 1包括3个CSI-RS Resource Set，每个CSI-RS Resource Set包括2个用于干扰测量的NZP CSI-RS Resource(A,C)和1个用于干扰测量的ZP CSI-RS Resource(D)中的至少一个，所述终端设备可根据用于信道测量的NZP CSI-RS Resource(A)和CSI-RS Resource Set#1、CSI-RS Resource Set#3进行测量，可以得到2个CSI报告，可根据用于信道测量的NZP CSI-RS Resource(B)和这3个CSI-RS Resource Set进行测量，可以得到3个CSI报告，即所述终端设备根据CSI-RS Resource Set #1进行测量可以得到2个CSI报告，根据CSI-RS Resource Set#2进行测量可以得到1个CSI报告，根据CSI-RS Resource Set#3进行测量可以得到2个CSI报告。
可以理解的是，该种可能实现的方式可以对应于所述网络设备配置所述终端设备周期性上报的情况，也可以对应于所述网络设备配置所述终端设备非周期性上报的情况，也可以对应于所述网络设备配置所述终端设备半持续性上报的情况。
在一种可能实现的方式中，所述终端设备可根据所述至少一个CSI上报配置信息对应的M个CSI-RS资源集合中N个CSI-RS资源集合进行测量，所述N个CSI-RS资源集合的数量可由所述网络设备进行指示，N为正整数，1≤N≤M。

在一种可能实现的方式中，所述终端设备可根据所述至少一个CSI上报配置信息对应的M个CSI-RS资源集合中N个CSI-RS资源集合进行测量，所述N个CSI-RS资源集合中每个CSI-RS资源集合的标识由所述网络设备进行指示，N为正整数，1≤N≤M。
可以理解的是，该种可能实现的方式可以对应于所述网络设备配置所述终端设备非周期上报的情况，也可以对应于所述网络设备配置所述终端设备半持续性上报的情况。
具体地，所述网络设备向所述终端设备发送测量资源指示信息，所述测量资源指示信息指示所述终端设备根据N个CSI-RS资源集合进行测量，即测量所述N个CSI-RS资源集合的干扰。所述终端设备在接收到所述测量资源指示信息的情况下，根据所述N个CSI-RS资源集合进行测量。
可选地，所述测量资源指示信息还可以指示所述N个CSI-RS资源集合中每个CSI-RS资源集合的标识。
可选地，在用于信道测量的资源配置信息包括的NZP CSI-RS资源的数量大于1的情况下，所述测量资源指示信息还可以指示与所述N个CSI-RS资源集合中每个CSI-RS资源集合具有对应关系的NZP CSI-RS资源的标识，例如，指示CSI-RS资源集合#2以及与其具有对应关系的NZP CSI-RS资源(A)。
可选地，在用于信道测量的资源配置信息包括的NZP CSI-RS资源的数量大于1的情况下，所述测量资源指示信息指示对应关系的标识，例如，指示对应关系1，即指示所述终端设备根据NZP CSI-RS resource(A)与CSI-RS Resource Set#1进行测量，那么所述终端设备根据NZP CSI-RS resource(A)、NZP CSI-RS resource(C)和ZP CSI-RS resource(D)进行测量。
所述测量资源指示信息可通过动态信令发送，所述动态信令可以是媒体接入控制控制元素(Media Access Control-Control Element，MAC-CE)，或其它层二信令。所述动态信令还可以是下行控制信息(Downlink Control Information，DCI)。
在用于信道测量的资源配置信息包括的NZP CSI-RS资源的数量等于1的情况下，所述测量资源指示信息可通过以下两种方式来指示所述N个CSI-RS资源集合、所述N个CSI-RS资源集合中每个CSI-RS资源集合的标识中的至少一种：
方式一，所述N个CSI-RS资源集合可通过S比特的位图(bit-map)进行指示。当S 比特中的某个比特位置位时，指示终端设备测量与该比特位对应的CSI-RS Resource Set，S比特中置位的数量即为N的数值。基于图7，S表示Resource Setting 1所包括的CSI-RS Resource Set的数量，通过4比特来指示所述N个CSI-RS Resource Set。例如，“0001”表示N＝1，表示所述网络设备选择激活CSI-RS Resource Set#1，指示终端设备测量CSI-RS Resource Set#1。再例如，“1010”表示N＝2，所述网络设备选择激活CSI-RS Resource Set#4和CSI-RS Resource Set#2，指示终端设备测量CSI-RS Resource Set#4和CSI-RS Resource Set#2。
方式二，所述N个CSI-RS资源集合可通过

CSI-RS resource set序号 2比特指示
1 00
2 01
3 10
4 11
例如，2比特表示N＝1，通过2比特来指示一个CSI-RS Resource Set，“11”表示所述网络设备选择激活CSI-RS Resource Set#4，指示终端设备测量CSI-RS Resource Set#4。再例如，4比特表示N＝2，通过4比特来指示两个CSI-RS Resource Set，“1101”表示所述网络设备选择激活CSI-RS Resource Set#4和CSI-RS Resource Set#2，指示终端设备测量CSI-RS Resource Set#4和CSI-RS Resource Set#2。
除上述两种方式外，所述网络设备还可以采用其它指示方式进行指示，具体采用哪种指示方式在本发明实施例中不做限定。所述网络设备所采用的指示方式，可以预先告知所述终端设备，以便所述终端设备测量的CSI-RS资源集合与所述网络设备指示的CSI-RS资源集合相同。
通过所述网络设备指示所述终端设备选择性测量，并根据CSI-RS资源集合进行干扰测量，在协作基站数量增加的情况下，可以节省测量资源指示开销。
步骤S205：所述终端设备向所述网络设备发送CSI测量结果；
具体地，所述终端设备向所述网络设备发送CSI测量结果，所述CSI测量结果包括CSI报告，一个CSI-RS资源集合对应至少一个CSI报告。
在一种可能实现的方式，所述CSI测量结果包括M’个CSI报告，即对应M个CSI-RS资源集合上报M’个CSI报告，即上报所有CSI-RS资源集合中每个CSI-RS资源集合对应的至少一个CSI报告。所述CSI测量结果还可以包括所述M’个CSI报告中每个CSI报告对应的CSI-RS资源集合的标识。该种可能实现的方式，默认所述终端设备测量了M个CSI-RS资源集合，并默认上报全部的CSI报告。其中，M’为正整数，M≤M’，在一个CSI-RS资源集合对应一个CSI报告的情况下，M＝M’。
可以理解的是，该种可能实现的方式可以对应于所述网络设备配置所述终端设备周期性上报的情况，也可以对应于所述网络设备配置所述终端设备非周期性上报的情况，也可 以对应于所述网络设备配置所述终端设备半持续性上报的情况。

方式二：所述终端设备采用

比特指示CSI-RS资源集合的标识。基于图7，假设TRP 1指示终端设备对CSI-RS Resource Set#1—CSI-RS Resource Set#4进行干扰测量，即N＝4，且TRP 1进一步指示终端设备上报一个CSI报告，即L＝1，那么终端设备上报一个CSI报告，并采用2比特指示该CSI报告对应的CSI-RS Resource Set的标识。例如，终端设备上报的该CSI报告对应于CSI-RS Resource Set#3，则终端设备在上报该CSI报告的同时，可上报2比特“10”(可参见步骤S204中的表)，指示该CSI报告对应的CSI-RS Resource Set的序号为3。
基于图7，再假设TRP 1指示终端设备对CSI-RS Resource Set#1—CSI-RS Resource Set #4进行干扰测量，即N＝4，且TRP 1进一步指示终端设备上报两个CSI报告，即L＝2，那么终端设备上报两个CSI报告，并采用4比特指示这两个CSI报告所对应的CSI-RS Resource Set的标识。例如，终端设备上报的两个CSI报告对应于CSI-RS Resource Set#1和CSI-RS Resource Set#3，则终端设备在上报这两个CSI报告的同时，可上报4比特“0010”，指示这两个CSI报告对应的CSI-RS Resource Set的序号分别为1和3。

具体地，所述网络设备接收所述终端设备发送的所述CSI测量结果，可根据所述CSI测量结果确定多基站协作传输方案，相应的链路自适应配置以及调度策略。
在图4所示的实施例中，网络设备通过配置并发送至少一个CSI上报配置信息，至少一个CSI上报配置信息对应的资源配置信息，以便终端设备根据至少一个CSI上报配置信息对应的资源配置信息进行测量，在协作基站数量增加的情况下，只需增加配置CSI-RS资源集合的个数，无需增加CSI上报配置信息或资源配置信息的数量，可以使系统具有可扩展性。并且多个CSI-RS资源集合之间可共享相同的CSI-RS资源，可以节省下行传输资源，可以提高测量资源和测量结果的共享程度。
