Description

确定天线端口的QCL的方法和设备
本申请要求于2017年05月05日提交中国专利局、申请号为201710311761.2、申请名称为“确定天线端口的QCL的方法和设备”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
本申请涉及通信领域，并且更具体地，涉及一种确定天线端口的QCL的方法和设备。
背景技术
现有的LTE系统中，TM10支持多点协作传输(Coordination multiple point,CoMP)。协议中定义了天线准共址(Quasi-co-located，QCL)，“从QCL的天线端口发送出的信号会经过相同的大尺度衰落，大尺度衰落包括时延扩展、多普勒扩展、多普勒频移、平均信道增益和平均时延。”
在非相干联合传输(non-coherent Joint Transmission，NCJT)情况下，由于不同的传输点(Transmission point,TP，或者transmission reception point，TRP)例如，网络设备，可以在同一载波内相同的时频资源上传不同的多输入多输出(Multiple-Input Multiple-Output，MIMO)数据流(MIMO layers)给同一终端设备，因此，第一传输点上的解调参考信号(Demodulation Reference Signal，DMRS)天线端口(DMRS ports)与信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)天线端口(CSI-RS ports)为QCL的，第二传输点上的DMRS天线端口与CSI-RS天线端口为QCL的，而第一传输点和第二传输点之间的天线端口为非QCL的。
为了使得终端设备能够正确接收和解调信号，终端设备需要知道上述天线端口的QCL关系，以便根据该QCL关系对数据进行解调处理。
然而，现有技术中，网络设备没有对终端设备配置上述端口的QCL关系，导致终端设备无法获取上述QCL关系，影响网络性能。
因此，终端设备如何确定各导频天线端口之间的QCL关系，成为亟待解决的问题。
发明内容
本申请提供一种确定天线端口的QCL的方法和设备，能够使得终端设备确定各导频天线端口之间的QCL关系。
第一方面，提供了一种确定天线端口的QCL的方法，该方法包括
网络设备生成下行控制信息DCI，该DCI包括QCL指示信息，该QCL指示信息用于终端设备从多种组合信息中确定与该QCL指示信息对应的组合信息，其中，该多种组合信息中的第一组合信息用于指示至少一组第一天线端口信息与第二天线端口信息的QCL关系；
该网络设备向该终端设备发送该DCI。
换句话说，网络设备生成下行控制信息DCI，所述DCI包括QCL指示信息，所述QCL指示信息用于指示多种组合信息中的一种组合信息，其中，所述多种组合信息中的一个或多个第一组合信息用于指示至少两组第一天线端口信息与第二天线端口信息的QCL关系；
所述网络设备向所述终端设备发送所述DCI。
应理解，该QCL指示信息所指示的上述一种组合信息可以为上述第一组合信息。
应理解，该第一天线端口例如可以为DMRS天线端口，该第二天线端口例如可以为CSI-RS天线端口。第一天线端口和第二天线端口还可以为其他的天线端口，本申请实施例并不限于此。
因此，本申请实施例中通过DCI能够指示第一天线端口和第二天线端口(例如，DMRS天线端口和CSI-RS天线端口)的QCL关系，使得终端设备根据该DCI能够确定该第一天线端口和第二天线端口的QCL关系，解决了现有技术的问题，能够提升网络性能。
本申请实施例中该多种组合信息可以与多个QCL指示信息具有一一对应关系，该多种组合信息与多个QCL指示信的一一对应关系可以是协议规定的，也可以是预先配置的，也就是说网络设备和终端设备可以预先获取该多种组合信息，以及该多种组合信息与多个QCL指示信息的一一对应关系。
该DCI中包括一个QCL指示信息，该一个QCL指示信息可以为2个比特的PQI。其中PQI的不同取值可以对应不同的组合信息。该一个QCL指示信息是上述多个QCL指示信息中的一个，这样终端设备可以通过该一个QCL指示信息(例如，PQI域)从多种组合信息中确定与该一个QCL指示信息对应的一种组合信息。
该第一组合信息可以指示一组第一天线端口信息第二天线端口信息的QCL关系。也可以指示两组或多组第一天线端口信息与第二天线端口信息的QCL关系，例如，指示三组、四组等第一天线端口信息与第二天线端口信息的QCL关系，本申请实施例并不限于此。
可选地，作为第一方面的一种实现方式，该第一组合信息用于指示第一组第一天线端口信息和第一组第二天线端口信息的QCL关系，第二组第一天线端口信息和第二组第二天线端口信息的QCL关系。
应理解，本申请实施例中组合信息具有多种形式，下面将详细描述各个情况下的组合信息，并分情况描述本申请实施例中该多个组合信息与多个QCL指示信息的一一对应关系。
可选地，作为第一方面的一种实现方式，该第一组合信息包括第一码字和第一参数集合的对应关系，以及第二码字和第二参数集合的对应关系；
其中，该第一码字对应该第一组第一天线端口信息，该第二码字对应该第二组第一天线端口信息，该第一参数集合对应该第一组第二天线端口信息，该第二参数集合对应该第二组第二天线端口信息。
也就是说，该第一组合信息指示了两个码字与两个参数集合的一一对应关系。其中，由于一个码字可以对应一组第一天线端口信息，一个参数集合可以对应一组第二天线端口信息，因此，该第一组合信息最终指示了两组第一天线端口与第二天线端口的QCL关系。
因此，本申请实施例通过DCI能够指示第一天线端口和第二天线端口(例如，DMRS天线端口和CSI-RS天线端口)的QCL关系，使得终端设备根据该DCI能够确定该第一天线端口和第二天线端口的QCL关系，解决了现有技术的问题，能够提升网络性能。
可选地，作为第一方面的一种实现方式，第一参数集合包括以下参数：
小区参考信号CRS的天线端口，CRS的频率偏移，多播/组播单频网络的子帧配置，零功率信道状态信息参考信号CSI-RS配置，下行共享数据信PDSCH的起始位置，和共址非零功率CSI-RS配置；
第二参数集合包括以下参数：
小区参考信号CRS的天线端口，CRS的频率偏移，多播/组播单频网络的子帧配置，零功率信道状态信息参考信号CSI-RS配置，下行共享数据信PDSCH的起始位置，和共址非零功率CSI-RS配置。
可选地，作为第一方面的一种实现方式，该第一组合信息包括第一个天线端口组标识和第一参数集合的对应关系，以及第二个天线端口组标识和第二参数集合的对应关系；
其中，该第一个天线端口组标识对应该第一组第一天线端口信息，该第二个天线端口组标识对应该第二组第一天线端口信息，该第一参数集合对应该第一组第二天线端口信息，该第二参数对应该第二组第二天线端口信息。
其中，该第一码字对应该第一组第一天线端口信息，该第二码字对应该第二组第一天线端口信息，该第一参数集合对应该第一组第二天线端口信息，该第二参数对应该第二组第二天线端口信息。
也就是说，该第一组合信息指示了第一天线的天线端口组标识(例如，DMRS天线端口组标识)与参数集合的一一对应关系。其中，由于第一天线的天线端口组标识对应一组第一天线端口，一个参数集合对应一组第二天线端口信息，因此，该第一组合信息最终指示第一天线端口与第二天线端口的QCL关系。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例可应用于各种通信系统，因此，下面的描述不限制于特定通信系统。例如，本申请实施例可以应用于全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)，以及下一代通信系统，即第五代(5th Generation，5G)通信系统，例如，新空口(New Radio，NR)系统。
图1示出了适用于本申请实施例的无线通信系统100示意性框图。该无线通信系统100可以包括第一网络设备110、第二网络设备120，以及位于第一网络设备110和第二网络设备120覆盖范围内的一个或多个终端设备130。该终端设备130可以是移动的或固定的。第一网络设备110和第二网络设备120均可以与终端设备130通过无线空口进行通信。第一网络设备110和第二网络设备120可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。
应理解，本申请实施例中“第一”、“第二”等仅仅是为了区分，第一、第二并不作为对本申请实施例的限定。
该第一网络设备110或第二网络设备120可以是全球移动通讯(Global System of Mobile communication，GSM)或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)中的基站(NodeB，NB)，还可以是长期演进(Long Term Evolution，LTE)中的演进型基站(Evolutional Node B，eNB/eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及未来5G网络中的网络侧设备，例如，NR系统中传输点(TRP或TP)、NR系统中的基站(gNB)、5G系统中的基站的一个或一组(包括多个天线面板)天线面板等。本申请实施例对此并未特别限定。
终端设备130也可以称为用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、无人机设备以及未来5G网络中的终端设备。
该无线通信系统100可以支持CoMP传输，即至少两个网络设备(传输点)采用协同多点传输方式向终端设备传输下行数据，换句话说，该终端设备130可以也可以在相同载波上与第一网络设备110通信，也可以与第二网络设备120通信，其中，协同多点传输方式可以采用空间分集和/或空间复用等技术实现，本申请对此不做限定。
本申请中的“协作多点传输”包括但不限于联合传输JT。JT包括相干JT和非相干JT(NCJT)，两者的区别在于NCJT对来自多个协作TP的不同的MIMO数据流分别做波束赋形，相干JT对来自多个协作TP的所有MIMO数据流做联合做波束赋形。本申请主 要涉及NCJT场景下确定天线端口的QCL的方法。
在本申请实施例中，第一网络设备可以作为服务网络设备，该第二网络设备可以为协作网络设备；或者，第一网络设备可以为协作网络设备，第二网络设备为服务网络设备。
在应用协同多点传输的场景中，该服务网络设备可以向终端设备发送控制信令，该协作网络设备可以向终端设备发送数据；或者，该服务网络设备可以向终端设备发送控制信令，该服务网络设备和该协作网络设备可以同时向该终端设备发送数据，或者，该服务网络设备和该协作网络设备可以同时向终端设备发送控制信令，并且该服务网络设备和该协作网络设备可以同时向该终端设备发送数据。本申请实施例对此并未特别限定。所述服务网络设备和协作网络设备之间以及多个协作网络设备之间可以进行通信，例如进行控制消息的传递。
以第一网络设备为服务网络设备，第二网络设备为协作网络设备为例，该第二网络设备的数量可以是一个或多个，且与第一网络设备为满足不同准共址(Quasi-Co-Location，QCL)的网络设备。应理解，第一网络设备和第二网络设备也可以都为服务网络设备本申请实施例并不限于此。
网络侧设备可通过满足准共址的天线端口，根据现有技术中码字到层、层到天线端口的映射关系，向用户设备传输数据。但是，当终端设备在没有获取到该QCL关系时，则会影响信道估计的精度以及数据解调的性能。
在现有的LTE协议中，定义了两种类型(类型A(Type-A)和类型B(Type-B))的QCL配置。其中，Type-A定义了一个TP的QCL配置，即，该TP的天线端口(包括CRS、DMRS以及CSI-RS)是满足QCL的；Type-B定义了多个TP间的QCL配置，多个TP间的QCL配置可以通过DCI中的PDSCH资源映射和准共址指示(PDSCH RE mapping and Quasi-Co-Location indicator，PQI)(2bits)来指示。PQI具体用来指示满足QCL的信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)的准共址关系。在本申请实施例中，Type-A可以对应于NR中同一网络设备同一天线面板的情形，Type-B可以对应于NR中同一网络设备不同天线面板的情形，以及NR中不同网络设备的情形。
已有的方案中，例如，上述LTE定义的Type-B中，由于所有的DMRS天线端口均为QCL,因此通过DCI中的PQI仅指示CSI-RS天线端口的准共址关系即可，网络设备没有对终端设备配置DMRS天线端口与CSI-RS天线端口的QCL关系，导致终端设备无法获取DMRS天线端口与CSI-RS天线端口的关系，影响终端设备信道估计的精度以及数据解调的性能，影响网络性能。
本申请实施例题提出了一种确定天线端口的QCL的方法，能够使得终端设备获取DMRS与CSI-RS天线端口的QCL关系，能够解决现有技术的问题，提升网络性能。
应理解，本申请实施例中QCL的定义可以参考LTE中的定义，即从QCL的天线端口发送出的信号会经过相同的大尺度衰落，大尺度衰落包括时延扩展、多普勒扩展、多普勒频移、平均信道增益和平均时延。但本申请实施例并不限于此，例如，大尺度衰落还可以包括空域信息，例如发射角(AOA)、到达角(AOD)、信道相关矩阵和功率扩展谱等，该QCL的定义还可以参考未来5G中的相关定义。
以下，为了便于理解和说明，作为示例而非限定，对本申请中的确定天线端口的QCL 的方法在通信系统中的执行过程和动作进行说明。
图2是根据本申请一个实施例的确定天线端口的QCL的方法200的示意性流程图。图2所示的方法可以应用于如图1所示支持CoMP的通信系统中。如图2所示的方法200包括：
210，网络设备生成下行控制信息DCI。
具体地，该DCI包括QCL指示信息，该QCL指示信息用于终端设备从多种组合信息中确定与该QCL指示信息对应的组合信息，其中，该多种组合信息中的第一组合信息用于指示至少一组第一天线端口信息与第二天线端口信息的QCL关系；
应理解，该第一天线端口例如可以为DMRS天线端口，该第二天线端口例如可以为CSI-RS天线端口。第一天线端口和第二天线端口还可以为其他的天线端口，本申请实施例并不限于此。
应理解，该网络设备可以是上述图1中的第一网络设备或第二网络设备，该网络设备还可以是第一网络设备和第二网络设备之外的其他网络设备，例如，在第一网络设备和第二网络设备均为协作网络设备时，该网络设备可以为服务网络设备，本申请实施例并不限于此。
应理解，本申请实施例的DCI格式，例如可以是DCI格式(format)2D，还可以是其它DCI格式或者未来5G定义的其它DCI格式。本申请实施例对此不作具体限定。
本申请实施例中该多种组合信息可以与多个QCL指示信息具有一一对应关系，该多种组合信息与多个QCL指示信的一一对应关系可以是协议规定的，也可以是预先配置的，也就是说网络设备和终端设备可以预先获取该多种组合信息，以及该多种组合信息与多个QCL指示信息的一一对应关系。
该DCI中包括一个QCL指示信息，该一个QCL指示信息可以为2个比特的PQI。其中PQI的不同取值可以对应不同的组合信息。该一个QCL指示信息是上述多个QCL指示信息中的一个，这样终端设备可以通过该一个QCL指示信息(例如，PQI域)从多种组合信息中确定与该一个QCL指示信息对应的一种组合信息。
具体而言，在PDSCH传输时，网络设备可以通过高层信令，例如RRC信令配置上述多种组合信息，或者，网络设备和终端设备可以预先协商保存上述多种组合信息。在PDCCH传输时，网络设备可以在PDSCH上发送DCI，DCI可以通过信息比特(即，QCL指示信息，例如，PQI域)来指示所对应的一种组合信息。该终端设备基于该组合信息确定第一天线端口信息与第二天线端口信息的QCL关系，进而终端设备根据该QCL关系参数进行速率匹配等处理。
例如，该多种组合信息与QCL指示信息的对应关系(也可以称为映射关系)如表1所示。具体的，如表1所示，当该DCI中的QCL指示信息即PQI域的值为“10”时表示与该“10”对应的组合信息3为终端设备当前数据传输所采用的，这样终端设备可以根据该组合信息3确定第一天线端口和第二天线端口的QCL关系。
因此，本申请实施例通过DCI能够指示第一天线端口和第二天线端口(例如，DMRS天线端口和CSI-RS天线端口)的QCL关系，使得终端设备根据该DCI能够确定该第一天线端口和第二天线端口的QCL关系，解决了现有技术的问题，能够提升网络性能。
表1
PQI域的值 与PQI域的值对应的组合信息
00 组合信息1
01 组合信息2
10 组合信息3
11 组合信息4
应理解，该组合信息的个数可以与PQI域的比特个数对应，例如，该组合信息的个数为2 n，n为PQI域的比特个数，该PQI域的比特取值为2 n种，n为大于1的正整数。
还应理解，本申请实施例中该组合信息的个数还可以小于2 n，例如，该组合信息的个数为2 n-k个，1≤k<2 n，该2n-k个组合信息与2n-k种PQI域的比特取值一一对应，其中，该2n种PQI域的比特取值中剩余的k种比特取值可以为保留比特位(reversed)，本申请实施例并不限于此。
还应理解，本文中以PQI域的值为2个比特为例进行举例说明，但本申请实施例并不限于此，在实际应用中该PQI域的值可以为1个比特、2个比特、3个比特或4个比特等。在PQI域的值的比特个数为其他值的情形，可以参照本文中PQI域的值为2个比特的例子，本文不再详述。
还应理解，本文中以QCL指示信息为PQI域的值为例进行说明，但本申请实施例并不限于此，该QCL指示信息还可以为其他名称，例如，未来5G中定义的相应名称。
应理解，本申请实施例中为了描述简便，仅以QCL指示信息为PQI域的取值为例进行描述，但本申请实施例并不限于此，该QCL指示信息还可以为其他的可行的信息，
还应理解，本文中以QCL指示信息与组合信息具有一一对应的关系为例进行描述，即一个QCL指示信息对应一个组合信息，但本发明实施例并不限于此，例如，预设的QCL指示信息的个数可以少于组合信息的个数，也就是说，一个QCL指示信息可以对应多个组合信息，或者，预设的QCL指示信息的个数多与组合信息的个数，也就是说，多个QCL指示信可以对应同一个组合信息等。
应理解，本申请实施例中，该第一组合信息可以为该多个组合信息中的任意一个，本申请实施例并不对此做限定。
该第一组合信息可以指示一组第一天线端口信息第二天线端口信息的QCL关系。也可以指示两组或多组第一天线端口信息与第二天线端口信息的QCL关系，例如，指示三组、四组等第一天线端口信息与第二天线端口信息的QCL关系，本申请实施例并不限于此。
可选地，作为另一实施例，该第一组合信息用于指示两组第一天线端口与第二天线端口的QCL关系，即该第一组合信息用于指示第一组第一天线端口信息和第一组第二天线端口信息的QCL关系，第二组第一天线端口信息和第二组第二天线端口信息的QCL关系。
例如，当终端设备处于非相干联合传输的场景下，该第一组合信息可以指示两组第一天线端口信息与第二天线端口信息的QCL关系。例如，该第一组合信息指示DMRS天线端口7与CSI-RS天线端口15的QCL关系(例如，DMRS天线端口7与CSI-RS天线端口15为图1中第一网络设备使用的天线端口)，以及，DMRS天线端口8与CSI-RS天 线端口16的QCL关系(例如，DMRS天线端口8与CSI-RS天线端口16为图1中第二网络设备使用的天线端口)。
应理解，本申请实施例中天线端口信息可以包括天线端口号、导频位置等，本申请实施例并不限于此。其中，第一天线端口信息可以对应至少一个第一天线端口，第二天线端口信息可以对应至少一个第二天线端口。
可选地，作为另一实施例，该多种组合信息中的第二组合信息用于指示一组第二天线端口信息。
具体而言，应用于动态点选择(Dynamic Point Selection，DPS)/动态点静默(Dynamic Point Blanking，DPB)场景下，即在单点传输场景下，该第二组合信息可以指示一组第二天线端口信息，例如，指示指少一个CSI-RS天线端口满足QCL关系。
应理解，该多个组合信息中的每个组合信息可以均与第一组合信息类似，可选地，该多个组合信息也可以既包括第一组合信息又包括第二组合信息，本申请实施例并不限于此。
因此，本申请实施例通过DCI能够指示第二天线端口(例如，CSI-RS天线端口)的QCL关系，可以兼容现有的单点传输的场景，且在非相干联合传输场景中能够通过DCI指示第一天线端口和第二天线端口(例如，DMRS天线端口和CSI-RS天线端口)的QCL关系，能够解决现有技术的问题，能够提升网络性能。
应理解，本申请实施例中组合信息具有多种形式，下面将详细描述各个情况下的组合信息，并分情况描述本申请实施例中该多个组合信息与多个QCL指示信息的一一对应关系。
情况一：
多种组合信息中的第一组合信息包括第一码字和第一参数集合的对应关系，以及第二码字和第二参数集合的对应关系；
该第一组合信息用于指示第一组第一天线端口信息和第一组第二天线端口信息的QCL关系，第二组第一天线端口信息和第二组第二天线端口信息的QCL关系，其中，该第一码字对应该第一组第一天线端口信息，该第二码字对应该第二组第一天线端口信息，该第一参数集合对应该第一组第二天线端口信息，该第二参数集合对应该第二组第二天线端口信息。
也就是说，该第一组合信息指示了两个码字与两个参数集合的一一对应关系。其中，由于一个码字可以对应一组第一天线端口信息，一个参数集合可以对应一组第二天线端口信息，因此，该第一组合信息最终指示了两组第一天线端口与第二天线端口的QCL关系。
应理解，用户面数据以及信令消息在到物理层由空口发送出去之前，需经分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)/无线链路控制(Radio Link Control，RLC)/媒体接入控制(Media Access Control，MAC)层的处理。在物理层处理的数据即MAC层的协议数据单元(Protocol Data Unit，PDU)，即，数据流。来自上层的数据流进行信道编码之后即为码字。不同的码字区分不同的数据流。由于码字的数量与发送天线数量不一致，可以将码字映射到不同的发射天线上，因此需要进行层映射和预编码。其中，层映射可以理解为，按一定的规则将码字重新映射到多个层；预编码可以理解为，将映射 到多个层的数据映射到不同的天线端口(为便于区分和说明，将码字映射至的天线端口记作数据天线端口)上。
网络设备将数据进行编码获得码字，将码字映射到层，再映射到数据天线端口，通过相应的数据天线端口向终端设备发送，并通过相应的数据天线端口发送DMRS，以便于终端设备根据DMRS对接收到的数据进行解调处理，获得原始数据。
因此，根据上述描述可以得到，码字与DMRS端口具有对应关系。以下结合图3详细说明码字与DMRS端口的对应关系。
具体地，如图3所示，一个码字(CW1)经过层映射，可以映射到一个层(层1)，然后映射到数据天线端口(例如，DMRS天线端口1，简称为天线端口1)，该数据天线端口属于第一网络设备。即，CW1对应的数据由该第一网络设备通过天线端口1发送给终端设备。相似地，另一个码字(CW2)经过层映射，可以映射到一个层(层2)，然后映射到数据天线端口(例如，DMRS天线端口1，简称为天线端口2)，该数据天线端口属于第二网络设备。即，CW2对应的数据由该TP2通过天线端口2发送给终端设备。也就是说，不同的网络设备可以传输不同的码字。此情况下，码字与层是对应的，层与数据天线端口是对应的，数据天线端口与网络设备也是对应的。
如表2所示，该多个组合信息中的第一组合信息包括第一码字(CW1)和第一参数集合(例如，高层配置的参数集合)的对应关系，以及第二码字(CW2)和第二参数集合(例如，高层配置的参数集合)的对应关系；
表2
Figure PCTCN2018085704-appb-000001
还应理解，第一参数集合和第二参数集合均可以为高层配置的参数集合。高层配置的参数集合可以理解为预配置或通过高层配置并通过RRC信令所下发的参数。该高层配置的参数集合可以包括以下内容：
1、CRS的天线端口(crs-PortsCount-r11)
2、CRS的频率偏移(crs-FreqShift-r11)
3、多播/组播单频网络(Multimedia Broadcast Multicast Service Single Frequency Network，MBSFN)的子帧配置(mbsfn-SubframeConfigList-r11)
4、零功率CSI-RS配置(csi-RS-ConfigZPId-r11)
5、PDSCH的起始位置(pdsch-Start-r11)
6、准共址非零功率CSI-RS配置(qcl-CSI-RS-ConfigNZPId-r11)
其中，不同的高层配置的参数集合中的各个参数的取值不完全相同。
应理解，本申请实施例中高层配置的参数集合还可以包括其他参数，并不限于上述列举的参数。
高层配置的参数集合中的准共址非零功率CSI-RS配置可用于确定CSI-RS天线端口(即第二天线端口)。因此，本申请实施例中由表2可知每组参数集合对应的CSI-RS天线端口与码字(例如CW1或CW2)对应的DMRS天线端口为QCL关系。
因此，根据表2终端设备可以根据该DCI中的指示信息确定一种组合信息，例如，在PQI域的值为11时，可以确定与11对应的组合信息，即“CW1，高层配置的参数集5；CW2，高层配置的参数集合6”，根据该组合信息终端设备即可确定DMRS天线端口与CSI-RS天线端口的QCL关系。
因此，本申请实施例通过DCI能够指示第一天线端口和第二天线端口(例如，DMRS天线端口和CSI-RS天线端口)的QCL关系，使得终端设备根据该DCI能够确定该第一天线端口和第二天线端口的QCL关系，解决了现有技术的问题，能够提升网络性能。
应理解，本申请实施例中第一码字和第二码字对应的参数集合可以相同，例如在PQI为00或01时，CW1和CW2对应的参数集合相同。这种情况下，对应动态点选择(Dynamic Point Select ion，DPS)/动态点静默(Dynamic Point Blanking，DPB)场景。
可选地，第一码字和第二码字对应的参数集合不同，例如在PQI为10或11时，CW1和CW2对应的参数集合不相同。这种情况下，对应NCJT场景。
可选地，在多个组合信息中的每个组合信息中的第一码字和第二码字对应的参数集合不同，即第一参数集合和第二参数集合不同时，本申请实施例中的表2可以替换成如下表2-1的形式，本申请实施例并不限于此。
表2-1

也就是说，该第一组合信息指示了第一天线的天线端口组标识(例如，DMRS天线端口组标识)与参数集合的一一对应关系。其中，由于第一天线的天线端口组标识对应一组第一天线端口，一个参数集合对应一组第二天线端口信息，因此，该第一组合信息最终指示第一天线端口与第二天线端口的QCL关系。
因此，本申请实施例通过DCI能够指示第一天线端口和第二天线端口(例如，DMRS天线端口和CSI-RS天线端口)的QCL关系，使得终端设备根据该DCI能够确定该第一天线端口和第二天线端口的QCL关系，解决了现有技术的问题，能够提升网络性能。

也就是说，该第一组合信息指示了两个CBG与两个参数集合的一一对应关系。其中，由于一个CBG可以对应一组第一天线端口信息，一个参数集合可以对应一组第二天线端口信息，因此，该第一组合信息最终指示了两组第一天线端口与第二天线端口的QCL关系。
因此，本申请实施例通过DCI能够指示第一天线端口和第二天线端口(例如，DMRS天线端口和CSI-RS天线端口)的QCL关系，使得终端设备根据该DCI能够确定该第一天线端口和第二天线端口的QCL关系，解决了现有技术的问题，能够提升网络性能。

情况四：
综上描述可知，在上述情况一至情况三中，高层预先配置的参数集合中包括第二天线端口相关集合的信息，不包括第一天线端口相关的信息，其中，在情况一至情况三中，第一天线端口与第二天线端口的对应关系是预配置的，不是通过高层信令配置的，网络设备通过高层仅配置对应第二天线端口信息的参数集合。

表8

还应理解，在情况四中，高层配置的参数集合可以理解为预配置或通过高层配置并通过RRC信令所下发的参数。该高层配置的参数集合例如可以包括以下内容：
1、CRS的天线端口(crs-PortsCount-r11)
2、CRS的频率偏移(crs-FreqShift-r11)
3、多播/组播单频网络(Multimedia Broadcast Multicast Service Single Frequency Network，MBSFN)的子帧配置(mbsfn-SubframeConfigList-r11)

8、DMRS的天线端口的第一指示信息
9、DMRS的天线端口的第二指示信息

可选地的，上述参数6至10可以使用以下参数11和12替换，本申请实施例并不限于此。
11、第一参数(例如，准共址非零功率CSI-RS配置(qcl-CSI-RS-ConfigNZPId-r11))，DMRS的天线端口的第一指示信息
12、第二参数(例如，准共址非零功率CSI-RS配置(qcl-CSI-RS-ConfigNZPId-r11))，DMRS的天线端口的第二指示信息
应理解，本申请实施例中高层配置的参数集合还可以包括其他参数，并不限于上述列举的参数。
其中，第一参数和第二参数的取值不同，第一参数和第二参数分别指示一组第二天线 端口信息，第一指示信息和第二指示信息不同，第一指示信息和第二指示信息分别指示一组第一天线端口信息。因此，在情况四中，每种组合信息(高层配置的新参数集合)通过第一参数与第一指示信息的对应关系，第二参数与第二指示信息的对应关系可以指示第一天线端口信息与第二天线端口信息的QCL关系。
因此，本申请实施例通过DCI能够指示第一天线端口和第二天线端口(例如，DMRS天线端口和CSI-RS天线端口)的QCL关系，使得终端设备根据该DCI能够确定该第一天线端口和第二天线端口的QCL关系，解决了现有技术的问题，能够提升网络性能。
应理解，为了与情况一至情况三中高层配置的参数集合区分，可以将情况四种如上述高层配置的参数集合，称为高层配置的新参数集合(以下称为新参数集合)，将情况一至情况三中高层配置的参数集合称为高层配置的旧参数集合(以下称为旧参数集合)。
还应理解，在情况四中，多种组合信息均可以为新参数集合，相应地，表8变为表9所示的形式。
表9
Figure PCTCN2018085704-appb-000009
可替代地，在情况四种，多种组合信息可以既包括新参数集合，又包括旧参数集合，例如，如表10所示，该多个组合信息可以包括第一组合信息即新参数集合(如表10中PQI为10或11时对应的组合信息)和第二组合信息即旧参数集合(如表10中PQI为00或01时对应的组合信息)。
应理解，在情况四中，在组合信息为旧参数集合时，可以对应DPS/DPB场景，在组合信息为新参数集合时，可以对应NCJT场景。
可以理解，在多种组合信息即包括新参数集合，又包括旧参数集合时，网络设备配置的DCI或者DCI中的QCL指示信息可以显示或者隐式的指示当前传输为DPS/DPB还是NCJT传输，本申请实施例并不对此做限定。
因此，本申请实施例通过DCI能够指示第二天线端口(例如，CSI-RS天线端口)的QCL关系，可以兼容现有的单点传输的场景，且在联合传输场景中能够通过DCI指示第一天线端口和第二天线端口(例如，DMRS天线端口和CSI-RS天线端口)的QCL关系，能够解决现有技术的问题，能够提升网络性能。
应注意，本申请实施例中通过表格的形式描述了该多个组合信息与多个QCL指示信息的一一对应关系(映射关系)，但本申请实施例并不限于此，本文中通过表格的形式仅是为了能够方便形象地描述该对应关系，在实际应用中，该对应关系可以为表格的形式，也可以为一串字符，或者为一段代码，本申请实施例并不限于此。

220，网络设备向终端设备发送该DCI。
相应地，终端设备接收该DCI。
230，终端设备根据该DCI确定天线端口的QCL关系。
具体的，终端设备根据该DCI中的QCL指示信息(例如，PQI域的取值)可以从上述四种情况中预配置的多组信息中确定与该QCL指示信息对应的组合信息，进而，终端设备可以根据该组合信息确定第一天线端口信息与第二天线端口信息的QCL关系，例如，确定DMRS天线端口与CSI-RS天线端口的QCL关系。
例如，在预配置的多种组合信息与QCL指示信息的对应关系为表2所示时，在QCL指示信息为PQI域的值为10时，终端设备可以确定CW1对应的DMRS天线端口与高层配置的参数集合3对应的CSI-RS天线端口为QCL关系，CW2对应的DMRS天线端口与高层配置的参数集合4对应的CSI-RS天线端口为QCL关系。
类似地，在预配置的多种组合信息与QCL指示信息的对应关系为表5所示时，在QCL指示信息为PQI域的值为10时，终端设备可以确定DMRS天线端口组标识3对应的DMRS天线端口与高层配置的参数集合3对应的CSI-RS天线端口为QCL关系，DMRS天线端口组标识4对应的DMRS与高层配置的参数集合4对应的CSI-RS天线端口为QCL关系。
在预配置的多种组合信息与QCL指示信息的对应关系为请他情况时，终端设备按照类似地方式，根据组合信息确定该QCL关系。此处为了避免重复，不再一一赘述。
在终端设备确定该QCL关系后，终端设备可以根据该QCL关系对数据进行解调处理等处理。应理解，在确定天线端口QCL关系后，终端设备可以按照已有标准中的规定进行相应的处理，本申请实施例并不对终端设备在确定天线端口QCL关系后的具体动作做限定。
因此，本申请实施例通过DCI能够指示第二天线端口(例如，CSI-RS天线端口)的QCL关系，可以兼容现有的单点传输的场景，且在联合传输场景中能够通过DCI指示第一天线端口和第二天线端口(例如，DMRS天线端口和CSI-RS天线端口)的QCL关系，能够解决现有技术的问题，能够提升网络性能。
应注意，上述情况一至情况四种的表2至表10中的高层配置的参数集合中还可以包括类似CRS的相关参数(即参数1至3)的另一套关于CRS的参数，即参数1’、参数2’和参数3’。其中参数1至3可以对应一个传输点，参数1’-参数3’可以对应另一个传输点。
例如，高层配置的参数集合可以包括：
1、CRS的天线端口(crs-PortsCount-r11)
2、CRS的频率偏移(crs-FreqShift-r11)
3、多播/组播单频网络(Multimedia Broadcast Multicast Service Single Frequency Network，MBSFN)的子帧配置(mbsfn-SubframeConfigList-r11)
1’、CRS的天线端口(crs-PortsCount-r11)
2’、CRS的频率偏移(crs-FreqShift-r11)
3’、多播/组播单频网络(Multimedia Broadcast Multicast Service Single Frequency Network，MBSFN)的子帧配置(mbsfn-SubframeConfigList-r11)
4…
其中其余参数可以与上述四种情况关于表2至表10中的高层配置的参数的相关描述，为了避免重复，此处不再赘述。
具体而言，网络设备在映射数据的时候，可以绕开该两套参数对应的CRS的RE位置，即在其他RE位置上发送业务数据，在这种情况下，网络设备可以通过DCI中PQI的值可以指示该两套CRS参数，进而终端设备根据该两套CRS参数确定上述CRS的RE位置，进而终端设备可以避开这些RE位置，即在其他RE位置上进行数据检测等处理，从而提升了数据解调的正确率，提升网络性能。
以上描述了在NCJT场景，或者支持DPS/DPB场景和NCJT场景下的高层配置的参数的情况。
在上述情况中，该DCI即可以指示QCL指示信息，也可以指示至少两套CRS参数，进而终端设备可以根据该QCL指示信息确定QCL关系，且可以根据该两套CRS参数进行速率匹配，提升网络性能。
下面描述在现有的PQI的基础上，例如，DPS/DPB场景下或者相干联合传输场景下，或者上述Type-B场景下，本申请实施例改进的高层配置的参数集合的情况。具体的如表11所示，PQI域的值可以与高层配置的参数集合对应。
例如，高层配置的参数集合可以包括：
1、CRS的天线端口(crs-PortsCount-r11)
2、CRS的频率偏移(crs-FreqShift-r11)
3、多播/组播单频网络(Multimedia Broadcast Multicast Service Single Frequency Network，MBSFN)的子帧配置(mbsfn-SubframeConfigList-r11)
1’、CRS的天线端口(crs-PortsCount-r11)
2’、CRS的频率偏移(crs-FreqShift-r11)
3’、多播/组播单频网络(Multimedia Broadcast Multicast Service Single Frequency Network，MBSFN)的子帧配置(mbsfn-SubframeConfigList-r11)
4、零功率CSI-RS配置(csi-RS-ConfigZPId-r11)
5、PDSCH的起始位置(pdsch-Start-r11)
6、准共址非零功率CSI-RS配置(qcl-CSI-RS-ConfigNZPId-r11)
其中，不同的高层配置的参见集合中的各个参数的取值不完全相同。
应理解，本申请实施例中高层配置的参数集合还可以包括其他参数，并不限于上述列举的参数。
具体而言，网络设备在映射数据的时候，可以绕开该两套参数对应的CRS的RE位置， 即在其他RE位置上发送业务数据，在这种情况下，网络设备可以通过DCI中PQI的值可以指示该两套CRS参数，进而终端设备根据该两套CRS参数确定上述CRS的RE位置，进而终端设备可以避开这些RE位置，即在其他RE位置上进行数据检测等处理，从而提升了数据解调的正确率，提升网络性能。
