Description

传输配置指示的发送、接收方法及装置、存储介质、基站、终端
本申请要求于2018年06月07日提交中国专利局、申请号为201810580903.X、发明名称为“传输配置指示的发送、接收方法及装置、存储介质、基站、终端”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
本发明涉及无线通信技术领域，具体地涉及一种传输配置指示的发送、接收方法及装置、存储介质、基站、终端。
背景技术
无线通信系统中，两个参考信号(Reference Signal，简称RS)占据的资源对应的天线端口(简称端口)关于部分大尺度参数准共站址(Quasi-Co-Location，简称QCL，也称为拟共站址)，则表明这两个端口的信道的这部分大尺度参数是相同的。其中，大尺度参数可以包括平均增益(average gain)、平均时延(Average delay)、时延扩展(Delay spread)、多普勒偏移(Doppler shift)、多普勒扩展(Doppler spread)、空间接收参数(Spatial receiving parameter)。
第五代移动通信(The Fifth-Generation mobile communications，简称5G)新无线(New Radio，简称NR，也称为新空口)技术引入传输配置指示(Transmission Configuration Indicator，简称TCI)概念指示准共站址。TCI是包含多个元素的列表，列表中的元素可以称为TCI状态。不同TCI状态采用不同TCI状态格式表示。当前，TCI状态格式包括单个RS和单个QCL类型(例如，{RS1|QCL-Type1})以 及两个RS和两个QCL类型的组合(例如，{RS1|QCL-Type1,RS2|QCL-Type2})。其中，RS1、RS2表示QCL的源RS，QCL-Type1、QCL-Type2表示QCL类型。
现有利用TCI状态进行TCI配置的方案只能服务于以下通信场景：(1)、单个目标RS与单个源RS关于QCL类型包含的大尺度参数准共站址；(2)、单个目标RS与第一个源RS关于第一QCL类型(例如，QCL-Type1)包含的大尺度参数准共站址，并与第二个源RS关于第二QCL类型(例如，QCL-Type2)包含的大尺度参数准共站址。其中，第一QCL类型与第二QCL类型包含的大尺度参数没有重叠。然而，如果TCI配置的通信场景发生改变，则现有的TCI配置方案可能无法提供与目标RS匹配的大尺度参数。

具体实施方式
本领域技术人员理解，如背景技术所言，现有的TCI状态配置方式仅适用于部分通信场景。
5G协议定义的QCL类型如下：(1)QCL-TypeA包括的大尺度参数组合为平均时延(Average delay)、时延扩展(Delay spread)、多普勒偏移(Doppler shift)、多普勒扩展(Doppler spread)；(2)QCL-TypeB包括的大尺度参数组合为多普勒偏移、多普勒扩展；(3)QCL-TypeC包括的大尺度参数组合为平均时延、多普勒偏移；(4)QCL-TypeD包括的大尺度参数组合为空间接收参数(Spatial receiving parameter)。
如果将TCI状态与目标RS关联，则表示源RS与目标RS关于QCL类型中的大尺度参数准共站址。例如，5G协议支持TCI状态{TRS#2|QCL-TypeB}，且与目标信道状态信息参考信号(Channel State Information Reference Signal，简称CSI-RS)关联，此时，源RS TRS#2与该CSI-RS关于QCL-TypeB包含的大尺度参数QCL。
再例如，5G协议支持TCI状态{TRS#2|QCL-TypeA,CSI-RS#5|QCL-TypeD}，且与物理下行共享信道(Physical Downlink Shared CHannel，简称PDSCH)DMRS关联。此时，TRS#2与该DMRS关于QCL-TypeA包含的大尺度参数QCL，且CSI-RS#5与该DMRS关于QCL-TypeD包含的大尺度参数QCL。
本申请发明人经仔细研究发现，目标RS配置的端口信道的大尺度特性可以通过源RS配置的端口信道的大尺度特性推算确定。例如，UE可以根据基站发送的准共站址配置信息，确定源CSI-RS配置的端口和目标DM RS配置的一个的端口是准共站址的。又例如，UE还可以根据基站发送的准共站址配置信息，确定源CSI-RS配置的天线端口和目标CRS配置的端口是准共站址的。
目前，尽管基于传输配置指示的准共站址信息是基于参考信号资源级别进行配置的，但实际配置的是RS资源内的端口。例如，两个参考信号关于准共站址类型QCL指的是两个RS资源内的任意两个端口之间都是关于该QCL-Type准共站址的。
当存在多面板(Multi-panel)、多传输参考点(Transmission Reference Point，简称TRP)或多波束(Multi-beam)时，每个RS资源内可能会分成多个端口组，每个端口组可以包括一个或多个端口。以两个端口组为例，此时，端口组1(简称为组1)可以与源RS关于一部分大尺度参数准共站址，组2可以与另外的源RS关于另外一部分大尺度参数准共站址。但是，现有TCI状态的配置机制无法支持部分端口与TCI状态关联。
本发明实施例提供一种传输配置指示的发送方法，包括：确定目标参考信号，并确定所述目标参考信号占据的资源对应的端口组，不同端口组中端口的大尺度参数不同；对于所述目标参考信号的每一端口组，确定与其准共站址的源参考信号，以及所述目标参考信号的各个端口组与所述源参考信号准共站址的准共站址类型，以得到扩展传输配置指示状态；向用户设备发送所述扩展传输配置指示状态和所述目标参考信号，以使所述用户设备确定所述目标参考信号中各个端口的大尺度参数。本发明实施例提供的技术方案可以支持部分端口与TCI状态关联。即使目标参考信号占据的资源对应的各个端口的大尺度参数不相同，仍然可以使用户设备得知所述目标参考信号各个端口的大尺度参数，解决了现有技术无法支持多面板、多传输参考点和多波束通信的TCI配置问题。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明实施的一种传输配置指示的发送方法的流程示意图。参考图1，所述传输配置指示的发送方法可以应用于网络侧，例如由网络侧的基站执行。具体而言，所述传输配置指示的发送方法可 以包括以下步骤：
步骤S101：确定目标参考信号，并确定所述目标参考信号占据的资源对应的端口组，不同端口组中端口的大尺度参数不同；
步骤S102：对于所述目标参考信号的每一端口组，确定与其准共站址的源参考信号，以及所述目标参考信号的各个端口组与所述源参考信号准共站址的准共站址类型，以得到扩展传输配置指示状态；
步骤S103：向用户设备发送所述扩展传输配置指示状态和所述目标参考信号，以使所述用户设备确定所述目标参考信号中各个端口的大尺度参数。
更具体而言，在步骤S101中，网络侧基站可以为源参考信号占据的资源对应的端口(以下简称为源参考信号的端口)和目标参考信号(Reference Signal，简称RS)占据的资源对应的端口(以下简称为目标RS的端口)确定关于哪些大尺度参数准共站址。
具体实施时，基站可以确定目标参考信号。所述目标参考信号可以得知该目标参考信号占据的资源对应的端口。如果所述目标参考信号的端口大尺度参数存在差异，则在确定所述目标参考信号之后，基站可以确定所述目标参考信号占据的资源对应的端口组(以下简称为目标RS的端口组)，不同端口组中端口的大尺度参数不同。例如，在多面板、多传输参考点和多波束通信场景中，所述目标参考信号占据的资源对应的端口可以分为多个端口组，不同端口组中的端口的大尺度参数可以不同。
作为一个非限制性实施例，所述端口组可以分为两个端口组，两个端口组分别称为组1和组2。
进一步，可以将同一发送链路的各个端口确定为同一端口组。例如，基站可以采用两个发送波束为一个UE同时发送同一物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)，两个发送波束对应两个不同的发送链路。两个发送波束可以分别通过不同参 考信号承载，此时，可以将同一发送链路的各个端口加入同一端口组中，该端口组中的各个端口的大尺度参数是相同的。反之，不同端口组中的各个端口的大尺度参数是不同的。
在步骤S102中，在确定所述目标参考信号的各个端口组之后，基站可以确定扩展传输配置指示状态，以使每一端口组与确定的TCI状态关联。也即，基站可以为每一端口组确定与其准共站址的源RS，以及该端口组中各个端口与该源RS的各个端口准共站址的准共站址类型。
进一步，所述扩展传输配置指示状态可以包括单个状态。其中，所述扩展TCI状态可以包括至少两个源参考信号和至少一个准共站址类型。
作为一个非限制性的实施例，所述扩展TCI状态可以包括：两个源参考信号和一个准共站址类型，每个源参考信号分别与该准共站址类型一一对应。例如，所述扩展TCI状态中单个状态的格式为{RS1，RS2|QCL-Type1}。其中，RS1、RS2均表示源参考信号，RS1、RS2可以是解调参考信号(Demodulation Reference Signal，简称DMRS)、CSI-RS等。QCL-Type1表示准共站址类型，可以是QCL-TypeA、QCL-TypeB、QCL-TypeC、QCL-TypeD中的一种。本领域技术人员理解，所述扩展TCI状态中单个状态的格式也可以为{RS1 RS2，QCL-Type1}或{RS1 RS2；QCL-Type1}或{RS1；RS2|QCL-Type1}或其他可以表明每个源参考信号分别与一个准共站址类型一一对应的格式。
以所述目标参考信号的端口组包括组1和组2为例，如果所述扩展TCI状态的格式为{RS1，RS2|QCL-Type1}，则表示组1与RS1关于QCL-Type1准共站址，组2与RS2关于QCL-Type1准共站址。也即，所述扩展TCI状态关联到所述目标RS时，如果该扩展TCI状态的格式为{RS1，RS2|QCL-Type1}，则表示组1中的各个端口与RS1中的各个端口关于QCL-Type1中的大尺度参数QCL，组2中的各个 端口与RS2中的各个端口关于QCL-Type1中的大尺度参数QCL。
图2是本发明实施例的一种TCI状态与目标RS的关联示意图。参考图2，TCI状态格式为{CSI-RS#1，CSI-RS#2|QCL-TypeA}。目标RS为CSI-RS#5。端口数为4，分为2组。其中，组1包含端口0和端口1；组2包含端口2和端口3。当CSI-RS#5与该TCI状态关联时，CSI-RS#5的端口0和端口1与CSI-RS#1关于QCL-TypeA QCL；端口2和端口3与CSI-RS#2关于QCL-TypeA QCL。
作为又一个非限制性的实施例，所述扩展传输配置指示状态可以包括两个源参考信号和两个准共站址类型，单个源参考信号分别与单个准共站址类型一一对应，所述两个准共站址类型包含的大尺度参数至少部分重叠。例如，所述扩展传输配置指示状态中单个状态的格式为{RS1|QCL-Type1，RS2|QCL-Type2}，其中，RS1、RS2表示源参考信号，RS1、RS2可以是DMRS、CSI-RS等。QCL-Type1、QCL-Type2表示准共站址类型，QCL-Type1和QCL-Type2可以有至少一部分相同的大尺度参数。且QCL-Type1、QCL-Type2均可以是QCL-TypeA、QCL-TypeB、QCL-TypeC、QCL-TypeD中的一种。本领域技术人员理解，所述扩展TCI状态中单个状态的格式也可以为{RS1 RS2，QCL-Type1 QCL-Type2}或{RS1 RS2；QCL-Type1 QCL-Type2}或{RS1；RS2|QCL-Type1；QCL-Type2}或{RS1|QCL-Type1；RS2|QCL-Type2}或其他可以表明单个源参考信号与单个准共站址类型一一对应的格式。
仍以所述目标参考信号的端口组包括组1和组2为例，如果所述扩展传输配置指示状态的格式为{RS1|QCL-Type1，RS2|QCL-Type2}，则表示组1与RS1关于QCL-Type1准共站址，组2与RS2关于QCL-Type2准共站址。也即，所述扩展传输配置指示状态关联到所述目标RS时，如果该扩展传输配置指示状态的格式为{RS1|QCL-Type1，RS2|QCL-Type2}，则表示组1中的各个端口与RS1中的各个端口关于QCL-Type1中的大尺度参数QCL，组2中的各个 端口与RS2中的各个端口关于QCL-Type2中的大尺度参数QCL。
作为另一个非限制性的实施例，所述扩展传输配置指示状态可以包括四个源参考信号和两个准共站址类型，每两个源参考信号对应一个准共站址类型，且两个准共站址类型中包含的大尺度参数不重叠。例如，所述扩展传输配置指示状态中单个状态的格式为{RS1，RS3|QCL-Type1，RS2，RS4|QCL-Type2}，其中，RS1、RS2、RS3、RS4均表示源参考信号，其中，RS1、RS2、RS3、RS4表示源参考信号，RS1、RS2、RS3、RS4可以是DMRS、CSI-RS等。QCL-Type1、QCL-Type2表示准共站址类型，QCL-Type1和QCL-Type2中包含的大尺度参数是完全不同的。QCL-Type1、QCL-Type2可以分别是QCL-TypeA、QCL-TypeB、QCL-TypeC、QCL-TypeD中的一种。本领域技术人员理解，所述扩展TCI状态中单个状态的格式为{RS1，RS3|QCL-Type1；RS2，RS4|QCL-Type2}或{RS1，RS3，QCL-Type1，RS2，RS4，QCL-Type2}或{RS1 RS3|QCL-Type1，RS2 RS4|QCL-Type2}或{RS1，RS3，QCL-Type1；RS2，RS4，QCL-Type2}或其他可以表明每两个源参考信号对应一个准共站址类型的格式。
仍以所述目标参考信号占据的资源对应的端口组包括组1和组2为例，如果所述扩展传输配置指示状态的格式为{RS1，RS3|QCL-Type1，RS2，RS4|QCL-Type2}，则表示组1与RS1关于QCL-Type1准共站址且与RS2关于QCL-Type2准共站址，组2与RS3关于QCL-Type1准共站址且与RS4关于QCL-Type2准共站址。也即，所述扩展传输配置指示状态关联到所述目标RS时，如果该扩展传输配置指示状态的格式为{RS1，RS3|QCL-Type1，RS2，RS4|QCL-Type2}，则表示组1中的各个端口与RS1中的各个端口关于QCL-Type1中的大尺度参数QCL，且与RS2中的各个端口关于QCL-Type2中的大尺度参数QCL；组2中的各个端口与RS3中的各个端口关于QCL-Type1中的大尺度参数QCL，且与RS4中的各个端口关于QCL-Type2中的大尺度参数QCL。
作为再一个非限制性的实施例，所述扩展传输配置指示状态可以包括四个源参考信号和四个准共站址类型，每个源参考信号对应一个准共站址类型，且对于所述四个准共站址类型，前两个准共站址类型中包含的大尺度参数不重叠，后两个准共站址类型包含的大尺度参数不重叠。也即，所述扩展传输配置指示状态关联到所述目标RS时，如果该扩展传输配置指示状态的格式为{RS1|QCL-Type1，RS2|QCL-Type2，RS3|QCL-Type3，RS4|QCL-Type4}，其中，RS1、RS2、RS3、RS4均表示源参考信号，QCL-Type1、QCL-Type2、QCL-Type3、QCL-Type4均表示准共站址类型；QCL-Type1和QCL-Type2中包含的大尺度参数是完全不同的，QCL-Type3、QCL-Type4中包含的大尺度参数是完全不同的。QCL-Type1、QCL-Type2、QCL-Type3、QCL-Type4可以是QCL-TypeA、QCL-TypeB、QCL-TypeC、QCL-TypeD中的一种。本领域技术人员理解，所述扩展TCI状态中单个状态的格式为{RS1，QCL-Type1，RS2，QCL-Type2，RS3，QCL-Type3，RS4，QCL-Type4}或{RS1|QCL-Type1；RS2|QCL-Type2；RS3|QCL-Type3；RS4|QCL-Type4}或{RS1 QCL-Type1，RS2 QCL-Type2，RS3 QCL-Type3，RS4 QCL-Type4}或{RS1 QCL-Type1；RS2 QCL-Type2；RS3 QCL-Type3；RS4 QCL-Type4}或其他可以表明四个源参考信号分别与四个准共站址类型一一对应的格式。
仍以所述目标参考信号占据的资源对应的端口组包括组1和组2为例，如果所述扩展传输配置指示状态的格式为{RS1|QCL-Type1，RS2|QCL-Type2，RS3|QCL-Type3，RS4|QCL-Type4}，则表示组1中的各个端口与RS1中的各个端口关于QCL-Type1中包含的大尺度参数是相同的，且与RS2中的各个端口关于QCL-Type2中包含的大尺度参数是相同的；组2中的各个端口与RS3中的各个端口关于QCL-Type3中包含的大尺度参数是相同的，且与RS4中的各个端口关于QCL-Type4中包含的大尺度参数是相同的。
图3是本发明实施例的又一种TCI状态与目标RS的关联示意图。 参考图3，TCI状态格式为{CSI-RS#7|QCL-TypeA,CSI-RS#1|QCL-TypeD,CSI#8|QCL-TypeA,CSI-RS#2|QCL-TypeD}。目标RS为CSI-RS#15，端口数为4，分为2组。其中，组1包含端口0和端口1；组2包含端口2和端口3。当CSI-RS#15与该TCI状态关联时，CSI-RS#15的端口0和端口1与CSI-RS#7关于QCL-TypeA QCL，且与CSI-RS#1关于QCL-TypeD QCL；端口2和端口3与CSI-RS#8关于QCL-TypeA QCL，且与CSI-RS#2关于QCL-TypeD QCL。
作为一个变化例，所述扩展传输配置指示状态可以包括两个状态或更多个状态，所述状态的数量可以与所述目标参考信号资源对应的所述端口组的数量相同。其中，每个状态可以包括源参考信号和准共站址类型。
进一步，每个状态格式可以为{RS1|QCL-Type1}或{RS2|QCL-Type2，RS3|QCL-Type3}，其中，RS1、RS2、RS3均表示源参考信号，RS1、RS2、RS3、RS4可以是DMRS、CSI-RS等。QCL-Type1、QCL-Type2、QCL-Type3表示准共站址类型，QCL-Type2和QCL-Type3中包含的大尺度参数是完全不同的。QCL-Type1、QCL-Type2和QCL-Type3可以分别是QCL-TypeA、QCL-TypeB、QCL-TypeC、QCL-TypeD中的一种。
进一步，如果所述目标参考信号的端口可以分为M个端口组，那么，对于第i个端口组，当第i个端口组对应的TCI状态格式为{RS1|QCL-Type1}时，第i个端口组与RS1关于QCL-Type1准共站址；当第i个端口组对应的TCI状态格式为{RS2|QCL-Type2，RS3|QCL-Type3}时，第i个端口组与RS2关于QCL-Type2准共站址且与RS3关于QCL-Type3准共站址。其中，M为大于等于2的正整数，i大于等于1，且小于等于M。
仍以所述目标参考信号的端口组包括组1和组2为例，如果所述扩展TCI状态的格式为{RS1|QCL-Type1}、{RS2|QCL-Type2， RS3|QCL-Type3}，则表示组1中的各个端口与RS1中的各个端口关于QCL-Type1中包含的大尺度参数是相同的；组2中的各个端口与RS2关于QCL-Type2中包含的大尺度参数是相同的，且与RS3中的各个端口关于QCL-Type3中包含的大尺度参数是相同的。
图4是本发明实施例的另一种TCI状态与目标RS的关联示意图。参考图4，TCI状态包括2个状态TCI#1和状态TCI#2。其中，状态TCI#1格式为{CSI-RS#7|QCL-TypeA,CSI-RS#1|QCL-TypeD}；状态TCI#2格式为{CSI-RS#8|QCL-TypeA,CSI-RS#2|QCL-TypeD}。目标RS为CSI-RS#15，端口数为4，且分为2组。其中，组1包含端口0和端口1；组2包含端口2和端口3。当CSI-RS#15与状态TCI#1和状态TCI#2关联时，CSI-RS#15的端口0和端口1与CSI-RS#7关于QCL-TypeA QCL，与CSI-RS#1关于QCL-TypeD QCL；端口2和端口3与CSI-RS#8关于QCL-TypeA QCL，与CSI-RS#2关于QCL-TypeD QCL。
图5是本发明实施例的再一种TCI状态格式与目标RS的关联示意图。参考图5，TCI状态包括2个状态TCI#1和状态TCI#2。其中，状态TCI#1为{CSI-RS#1|QCL-TypeA,CSI-RS#1|QCL-TypeD}，状态TCI#2状态为{CSI-RS#2|QCL-TypeA,CSI-RS#2|QCL-TypeD}。目标RS为PDCCH DMRS，端口数为1，此时，尽管目标RS仅有单个端口，但可以同时出现在组1和组2中，组1与CSI-RS#1关于QCL-TypeA中包含的大尺度参数QCL，且与CSI-RS#1关于QCL-TypeD中包含的大尺度参数QCL。
在步骤S103中，基站可以向UE显示发送所述扩展传输配置指示状态和所述目标参考信号。基站也可以向用户设备隐式发送所述扩展传输配置指示状态和所述目标参考信号。UE在接收到所述扩展传输配置指示状态和所述目标参考信号之后，可以根据所述扩展TCI状态包含的源参考信号和准共站址类型，得知所述目标参考信号中各个端口的大尺度参数。
作为一个非限制性实施例，参考图5，当基站采用两个发送链路(例如，两个发送波束)同时发送一个PDCCH时，由于存在空间接收参数配置信息(也即存在QCL-TypeD)，因而这两个发送波束可以分别通过CSI-RS#1和CSI-RS#2承载。相应地，UE可以采用两个面板接收该PDCCH。两个面板可以分别形成两个独立的接收波束，对应不同下行接收链路。例如，第一接收链路接收CSI-RS#1承载的发送波束，表示接收到的PDCCH DMRS与CSI-RS#1关于QCL-TypeA QCL；第二接收链路接收CSI-RS#2承载的发送波束，表示接收到的PDCCH DMRS与CSI-RS#2关于QCL-TypeA QCL。由此，UE可以得知两个接收链路对应的端口的大尺度参数。
图6是本发明实施的一种传输配置指示的接收方法的流程示意图。参考图6，所述传输配置指示的接收方法可应用于用户设备侧。具体地，所述接收方法可以包括以下步骤：
步骤S601：接收网络发送的扩展传输配置指示状态和目标参考信号；

在步骤S601中，UE可以显示或隐式地从网络接收到所述扩展传输配置指示状态和目标参考信号。
在步骤S602中，根据所述目标参考信号，UE可以确定所述目标参考信号占据的资源对应的端口组。作为一个非限制性的例子，对于所述目标参考信号占据的资源对应的端口，UE可以将属于同一接收 链路的各个端口确定为同一端口组。其中，不同端口组中的各个端口的准共站址类型不同，例如，不同端口组中端口的大尺度参数不同。
在步骤S603中，UE可以基于所述扩展传输配置指示状态，确定所述目标参考信号中各个端口的大尺度参数。其中，所述扩展传输配置指示状态包括所述目标参考信号的每一端口组与其准共站址的源参考信号，以及所述目标参考信号的各个端口组与所述源参考信号准共站址的准共站址类型。所述准共站址类型可以是以下一种：QCL-TypeA、QCL-TypeB、QCL-TypeC、QCL-TypeD。需要说明的是，每一端口组可以与单个源RS关于某些大尺度参数准共站址，也可以与多个源RS关于某些大尺度参数准共站址。当有多个端口组时，各个端口组与之共站址的源RS一般是不同的。
进一步，所述扩展传输配置指示状态可以包括单个状态，所述单个状态记录有至少两个源参考信号和至少一个准共站址类型。

例如，所述端口组包括组1和组2，所述扩展传输配置指示状态格式可以为{RS1|QCL-Type1，RS2|QCL-Type2}，其中，RS1、RS2均表示源参考信号，QCL-Type1、QCL-Type2均表示准共站址类型，QCL-Type1、QCL-Type2中包含的大尺度参数至少部分重叠，组1与RS1关于QCL-Type1准共站址，组2与RS2关于QCL-Type2准共站 址。
作为再一个非限制性的实施例，所述扩展传输配置指示状态可以包括：四个源参考信号和两个准共站址类型，且两个准共站址类型中包含的大尺度参数不重叠。
例如，所述端口组可以包括组1和组2，所述扩展传输配置指示状态格式为{RS1，RS3|QCL-Type1，RS2，RS4|QCL-Type2}，其中，RS1、RS2、RS3、RS4均表示源参考信号，QCL-Type1、QCL-Type2均表示准共站址类型，QCL-Type1、QCL-Type2中包含的大尺度参数不重叠，组1与RS1关于QCL-Type1准共站址且与RS2关于QCL-Type2准共站址，组2与RS3关于QCL-Type1准共站址且与RS4关于QCL-Type2准共站址。
