Description

传输信号的方法和装置
本申请要求于2019年1月11日提交的申请号为201910028826.1、发明名称为“传输信号的方法和装置”的中国专利申请以及于2019年12月2日提交的申请号为201911215742.5、发明名称为“传输信号的方法和装置”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
本申请涉及通信领域，并且更具体而言，涉及一种传输信号的方法和装置。
背景技术
在波束训练中，用户设备(user equipment，UE)通过对网络设备发送的多个发射波束进行测量，在多个发射波束中选出较优的N个波束，将该N个波束作为UE确定的接收波束，并通过波束测量信息(beam state information，BSI)将较优的N个波束上报给网络设备。
由于UE向网络设备上报的接收波束可能包括多个波束，网络设备可以通过向UE发送波束指示信息来向UE指示可用的接收波束。
已知一种波束指示方法，该方法仅考虑了在某一时刻仅有一个网络设备使用一个波束与UE通信的传输方式。然而，新无线(new radio，NR)系统可以支持网络设备同时使用不同的波束与一个UE通信。
此时，若UE仅有一个可用的接收波束，对于没有承载在该接收波束上的数据，可能会使得UE接收承载在其他接收波束上的数据的性能较差或者无法接收到承载在其他接收波束上的数据。
发明内容
本申请提供一种传输信号的方法，当在一段时间内存在至少两个参考信号资源上的数据需要接收时，该方法能够提高终端设备成功接收数据的概率。
第一方面，提供了一种传输信号的方法。该方法可以由终端设备执行，或者也可以由配置于终端设备中的芯片执行，本申请对此不作限定。
具体地，该方法包括：确定至少两个第一参考信号资源；当调度偏移值小于或等于预设的阈值和/或下行控制信息(downlink control information，DCI)中不存在空间相关参数信息指示字域时，根据所述至少两个第一参考信号资源，接收第一信道，解调所述第一信道。
基于上述技术方案，当调取偏移值小于或等于预设的阈值和/或下行控制信息DCI中不存在空间相关参数信息指示字域时，通过使终端设备确定至少两个参考信号资源(例如，至少两个第一参考信号资源)，在该至少两个第一参考信号资源上接收第一信道，从而当 在一段时间内存在至少两个参考信号资源上的数据需要接收时，通过使终端设备根据至少两个第一参考信号资源接收第一信道，从而提高终端设备成功接收数据的概率。
需要说明的是，上述调度偏移值是指用于调度第一信道的DCI的接收时刻与第一信道的接收时刻的偏移值，例如，用于调度第一信道的DCI的接收时刻为n+k，第一信道的接收时刻为n，则用于调度第一信道的DCI的接收时刻与第一信道的接收时刻的偏移值为k。
在一种可能的实现方式中，至少两个第一参考资源可以是终端设备最近一次上报的参考信号资源，所述至少两个第一参考信号资源上承载的至少两个参考信号是能够同时被接收的参考信号。
应理解，本申请实施例中，同时是指，在同一个时刻接收，或者重叠的时刻接收，或者在同一个时间单元接收，或者在至少一个重叠的时间单元接收，多个参考信号至少在一个时间单元重叠。所述时间单元可以是LTE或者5G NR系统中定义的一个或多个无线帧，一个或多个子帧，一个或多个时隙，一个或多个微时隙(mini slot)，一个或多个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，也可以是多个帧或子帧构成的时间窗口，例如系统信息(system information，SI)窗口。下述实施例以同时接收的参考信号为在一个或多个OFDM符号上接收到的参考信号为例进行说明，本申请对此不进行限定。

例如，第一空间相关参数信息中包括至少两个信道状态信息参考信号(channel state information reference signal，CSI-RS)资源，此外，第一空间相关参数信息中还包括与该至少两个CSI-RS资源相关联的空间相关参数的类型。例如，当第一空间相关参数信息中包括的与该至少两个CSI-RS资源相关联的空间相关参数的类型为准共址(quasi-collocation，QCL)类型D时，终端设备将该至少两个CSI-RS资源确定为至少两个第一参考信号资源。
在一种可能的实现方式中，终端设备可以通过无线资源控制(radio resource control，RRC)信令或媒体接入控制(media access control，MAC)控制元素(control element，CE)信令接收网络设备发送的配置信息，根据该配置信息，获取第一空间相关参数信息，该配置信息用于指示第一空间相关参数信息。相应地，网络设备可以通过RRC信令或MAC CE信令向终端设备发送配置信息。
例如，配置信息中可以包括一个或至少两个传输配置指示状态(transmission configuration indicator state，TCI-state)ID，TCI-state ID指示的TCI-state中可以包括至少一个参考信号资源的标识以及与至少一个参考资源相关联的空间相关参数的类型，其中标识可以为参考信号资源的索引值。当配置信息中包括一个TCI-state ID时，该TCI-state ID指示的TCI-state中可以包括至少两个参考信号资源的索引值以及与至少两个参考资源相关联的空间相关参数的类型；当配置信息中包括至少两个TCI-state ID时，每个TCI-state ID指示的TCI-state中可以包括至少一个参考信号资源的标识以及与至少一个参考信号资源相关联的空间相关参数的类型，本申请对此不作限定。

还需要说明的是，在本申请中，第一空间相关参数信息与第二空间相关参数信息可以通过相同的一个TCI-state或相同的两个TCI-state来指示，例如，一个TCI-state中可以包括至少两个第一参考信号资源与至少两个第二参考信号资源，与该至少两个第一参考信号资源相关联的空间相关参数的类型可以为QCL类型D，与该至少两个第二参考信号资源相关联的空间相关参数的类型可以为QCL类型A、QCL类型B与QCL类型C中的任意一种类型。再例如，一个TCI-state中可以包括至少两个第一参考信号资源中的至少一个第一参考信号资源与至少两个第二参考信号资源中的至少一个第二参考信号资源，与该至少一个第一参考信号资源相关联的空间相关参数的类型可以为QCL类型D，与该至少一个第二参考信号资源相关联的空间相关参数的类型可以为QCL类型A、QCL类型B与QCL类型C中的任意一种类型。另一个TCI state中包括至少两个第一至少两个第一参考信号资源中的另外的至少一个第一参考信号资源与至少两个第二参考信号资源中的另外的至少一个第二参考信号资源，与该另外的至少一个第一参考信号资源相关联的空间相关参数的类型可以为QCL类型D，与该另外的至少一个第二参考信号资源相关联的空间相 关参数的类型可以为QCL类型A、QCL类型B与QCL类型C中的任意一种类型。在一种可能的实现方式中，所述解调所述第一信道，包括：在所述至少两个第一参考信号资源中确定至少一个参考信号资源为目标参考信号资源；根据所述目标参考信号资源，解调所述第一信道。
在一种可能的实现方式中，所述在所述至少两个第二参考信号资源中确定至少一个第二参考信号资源为目标参考信号资源，包括：根据第一信息，在所述至少两个第二参考信号资源中确定至少一个第二参考信号资源为目标参考信号资源，所述第一信息是调度所述第一信道的DCI的相关信息。

可选地，在multi-TRP场景下，一个DCI调度的一份PDSCH可能来自一个TRP或多个TRP。一种可能的实现方式中，该PDSCH可以是来自一个TRP还是两个TRP是由该DCI中的TCI field确定的。
应理解，根据调度所述第一信道的DCI中携带的传输配置指示字域，在所述至少两个第一参考信号资源中确定至少一个参考信号资源为目标参考信号资源。一种可能的实施方式为，根据调度所述第一信道的DCI中携带的传输配置指示字域指示的TCI状态的个数(或者根据DCI传输配置指示字域的所有候选码点中每个码点指示的TCI状态的最大个数)，在所述至少两个第一参考信号资源中确定至少一个参考信号资源为目标参考信号资源。另一种可能的实施方式为，根据调度所述第一信道的DCI中携带的传输配置指示字域指示的TCI状态的个数以及TCI状态是否相同，在所述至少两个第一参考信号资源中确定至少一个参考信号资源为目标参考信号资源。
或者根据调度所述第一信道的DCI中携带的传输配置指示字域，在所述至少两个第二参考信号资源中确定至少一个参考信号资源为目标参考信号资源。一种可能的实施方式为，根据调度所述第一信道的DCI中携带的传输配置指示字域指示的TCI状态的个数(或 者根据DCI传输配置指示字域的所有候选码点中每个码点指示的TCI状态的最大个数)，在所述至少两个第二参考信号资源中确定至少一个参考信号资源为目标参考信号资源。另一种可能的实施方式为，根据调度所述第一信道的DCI中携带的传输配置指示字域指示的TCI状态的个数以及TCI状态是否相同，在所述至少两个第二参考信号资源中确定至少一个参考信号资源为目标参考信号资源。

本申请实施例中可以定义默认的两个TCI state，该两个TCI state指示的type D QCL信息(可以指示前文中的至少两个第一参考信号资源)缓存数据。当DCI解码完成后，可以使用该两个TCI state指示的type A/B/C QCL信息(可以指示前文中的至少两个第二参考信号资源)中的至少一种解调PDSCH。
可选地，PDSCH DMRS port的type D QCL信息可以是默认的两个TCI state中指示的type D QCL信息，PDSCH DMRS port的tyep A/B/C QCL信息可以是根据调度PDSCH的DCI中包含的TCI field的指示值确定的。
应理解，上述两个default TCI state可以是：第一个TCI state和第二个TCI state。第一个TCI state和第二个TCI state的实现方式有多种。
例如，第一个TCI state可以是最近的时隙中标识最小的CORESET的TCI state，第二个TCI state可以是激活的TCI state中的type D QCL RS与在最近的时隙中标识最小的CORESET的TCI state中的type D QCL RS。这两个参考信号资源(两个TCI state对应的type D QCL RS)是可以是一起分组上报，分组上报的这两个参考信号资源是可以被终端设备同时接收的参考信号资源。

又如，DCI的传输配置指示字域的所有码点中，指示两个TCI state的码点中的码点值最小的码点所指示的两个TCI state作为默认的两个TCI state。
应理解，确定两个TCI state还可以有其他方式，本申请对此不做限定。

当所述传输配置指示字域指示的传输配置指示状态(TCI state)个数为1时，确定所述至少两个第二参考信号资源中的第一个第二参考信号资源作为目标参考信号资源；
当所述传输配置指示字域指示的传输配置指示状态(TCI state)个数为2个时，确定所述至少两个第二参考信号资源中的两个第二参考信号资源作为目标参考信号资源。
一种可能的实现方式中，当调度偏移值小于或等于预设的阈值时，终端设备可以确定两个TCI state。并假设第一信道或第一信道的DMRS port的type D QCL与该两个TCI state中指示的type D QCL信息相同。并根据调度所述第一信道的DCI中携带的TCI字域的 取值，或，所述第一信道的DCI中携带的TCI字域指示的TCI state的个数，在所述两个TCI state中确定第一信道的type A、type B、type C QCL信息的一种。
可选地，当一个DCI用于调度多TRP，且TCI字域存在，且scheduling offset<K时，根据调度PDSCH的DCI中的TCI字域确定解调PDSCH的type A/B/C的QCL信息。下面对该过程进行详细描述。
1.确定两个default TCI state中的两个type D QCL用于接收scheduling offset<K的PDSCH。
2.根据调度PDSCH的DCI中的TCI field信息确定两个default TCI state中的至少一个TCI state指示的type A/B/C QCL用于解调该PDSCH。
应理解，当TCI field信息指示TCI state个数为1个时，可以根据default TCI state中的第一个TCI state指示的type A/B/C QCL解调该PDSCH。当TCI field信息指示TCI state个数为2个时，可以根据default TCI state中的两个TCI state指示的type A/B/C QCL解调该PDSCH。
例如，UE确定default TCI state是TCI n1{type A RS a1，type D RS b1}+TCI m1{type A RS c1，type D RS d1}。调度PDSCH的DCI指示的TCI field值为001，也即DCI指示TCI n2(type A RS a2，type D RS b2}。那么UE根据TCI n1指示的{type A RS a1)解调PDSCH。
在另一种可能的实现方式中，根据调度所述第一信道的DCI中携带的天线端口字域，在所述至少两个第二参考信号资源中确定至少一个参考信号资源为目标参考信号资源，包括：

在另一种可能的实现方式中，根据调度所述第一信道的DCI中携带的天线端口字域和传输配置指示字域，在所述至少两个第二参考信号资源中确定至少一个参考信号资源为目标参考信号资源，包括：
当所述天线端口字域指示的DMRS port所属的CDM group个数为1，且传输配置指示字域指示的传输配置指示状态(TCI state)个数为1时，确定所述至少两个二参考信号资源中的第一个第二参考信号资源作为目标参考信号资源；
当所述天线端口字域指示的DMRS port所属的CDM group个数为1，且传输配置指示字域指示的传输配置指示状态(TCI state)个数为2时，确定所述至少两个第二参考信号资源中的两个第二参考信号资源作为目标参考信号资源。
在另一种可能的实现方式中，根据所述重复次数指示信息指示的所述第一信道的重复次数，确定所述目标参考信号资源。例如，重复次数指示信息指示的重复次数为N，则当前调度包括N个第一信道，或者是N个时频资源，每个第一信道或者每个时频资源用于承载相同的传输块(Transmission Block，TB)。
在另一种可能的实现方式中，根据调度所述第一信道的DCI中携带的重复次数指示信息和传输配置指示字域，在所述至少两个第二参考信号资源中确定至少一个参考信号资源 为目标参考信号资源，包括：
当所述重复次数指示信息指示的重复次数为1或者为缺省状态，且传输配置指示字域指示的传输配置指示状态(TCI state)个数为1时，确定所述至少两个第二参考信号资源中的第一个第二参考信号资源作为目标参考信号资源；
当所述重复次数指示信息指示的重复次数为1或者为缺省状态，且传输配置指示字域指示的传输配置指示状态(TCI state)个数为2时，确定所述至少两个第二参考信号资源中的两个第二参考信号资源作为目标参考信号资源；
当所述重复次数指示信息指示的重复次数大于等于2，且传输配置指示字域指示的传输配置指示状态(TCI state)个数为2时，确定所述至少两个第二参考信号资源中的两个第二参考信号资源作为目标参考信号资源。
在另一种可能的实现方式中，根据传输机制指示信息和调度所述第一信道的DCI中携带传输配置指示字域，在所述至少两个第二参考信号资源中确定至少二个参考信号资源为目标参考信号资源，包括：
当所述传输机制指示信息指示为重复传输，且传输配置指示字域指示的传输配置指示状态(TCI state)个数为2时，确定第二信道中的参考信号资源作为目标参考信号资源；
当所述传输机制指示信息不指示为重复传输，且传输配置指示字域指示的传输配置指示状态(TCI state)个数为2时，确定第二信道中的参考信号资源作为目标参考信号资源。
可选的，所述传输机制指示信息中指示的重复传输是指，由调度所述第一信道的DCI指示的两个频域资源块分别对应不同的TCI状态；
可选的，两个频域资源块承载相同的TB；
可选的，不同的TCI状态为上述默认的两个TCI状态；
可选的，所述传输机制指示信息中指示的重复传输是指，两个TCI状态分别对应由调度所述第一信道的DCI指示的两个时域资源块；
可选的，两个时域资源块承载相同的TB；

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。
本申请的技术方案可以应用于各种通信系统，例如：全球移动通信(global system for mobile communications，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)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、未来的第五代(5th generation，5G)系统或新无线(new radio，NR)等。
为便于理解本申请，首先结合图1详细说明适用于本申请的通信系统。
图1示出了适用于本申请实施例的发送和接收信号的方法和装置的通信系统100的另一示意图。如图所示，该通信系统100可以包括至少两个网络设备，例如图1中所示的网络设备110和120；该通信系统100还可以包括至少一个终端设备，例如图1中所示的终端设备130。该终端设备130可以通过双连接(dual connectivity，DC)技术或者多连接技术与网络设备110和网络设备120建立无线链路。其中，网络设备110例如可以为主基站，网络设备110例如可以为辅基站。此情况下，网络设备110为终端设备130初始接入时的网络设备，负责与终端设备130之间的无线资源控制(radio resource control，RRC)通信，网络设备120可以是RRC重配置时添加的，用于提供额外的无线资源。
当然，网络设备120也可以为主基站，网络设备110也可以为辅基站，本申请对此不做限定。另外，图中仅为便于理解，示出了两个网络设备与终端设备之间无线连接的情形，但这不应对本申请所适用的场景构成任何限定。终端设备还可以与更多的网络设备建立无线链路。
各通信设备，如图1中的网络设备110、网络设备120或终端设备130，可以配置多个天线。该多个天线可以包括至少一个用于发送信号的发射天线和至少一个用于接收信号的接收天线。另外，各通信设备还附加地包括发射机链和接收机链，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。因此，网络设备与终端设备之间可通过多天线技术通信。
应理解，该无线通信系统中的网络设备可以是任意一种具有无线收发功能的设备。该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(Radio Network Controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station，BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)，无线保真(Wireless Fidelity，WIFI)系统中的接入点(Access Point，AP)、无线中继节点、无线回传节点等，还可以为5G，如，NR，系统中的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，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+CU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
还应理解，该无线通信系统中的终端设备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。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。
为便于理解本申请实施例，下面首先对本申请中涉及的几个术语做简单介绍。
1、波束：波束在NR协议中的体现可以是空域滤波器(spatial filter)，或者称空间滤波器(spatial filter)或空间参数(spatial parameters)。用于发送信号的波束可以称为发射波束(transmission beam，Tx beam)，可以称为空间发送滤波器(spatial domain transmit filter)或空间发射参数(spatial domain transmit parameter)；用于接收信号的波束可以称为接收波束(reception beam，Rx beam)，可以称为空间接收滤波器(spatial domain receive filter)或空间接收参数(spatial domain receive parameter)。
可选的，波束还可以与空域滤波器(spatial filter/spatial domain filter)，空域传输滤波器(spatial domain transmission filter)、空间滤波器、空间传输滤波器对应。其中，接收波束等价于空间传输滤波器，空域传输滤波器，空域接收滤波器，空间接收滤波器；发送波束可以等价于空域滤波器，空域传输滤波器，空域发送滤波器，空间发送滤波器。空间相关参数的信息等价于空间滤波器(spatial domain transmission/receive filter)。
进一步地，空间滤波器一般包括：空间发送滤波器，和/或，空间接收滤波器。该空间滤波器还可以称之为空域发送滤波器，空域接收滤波器，空间传输滤波器，空域传输滤波器等。可选的，终端侧的接收波束和网络设备侧的发送波束可以作为下行空间滤波器，终端侧的发送波束和网络设备侧的接收波束可以作为上行空间滤波器。
发射波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布， 接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。
应理解，上文列举的NR协议中对于波束的体现仅为示例，不应对本申请构成任何限定。本申请并不排除在未来的协议中定义其他的术语来表示相同或相似的含义的可能。
此外，波束可以是宽波束，或者窄波束，或者其他类型波束。形成波束的技术可以是波束赋形技术或者其他技术。波束赋形技术具体可以为数字波束赋形技术、模拟波束赋形技术或者混合数字/模拟波束赋形技术等。不同的波束可以认为是不同的资源。通过不同的波束可以发送相同的信息或者不同的信息。
可选地，将具有相同或者类似的通信特征的多个波束视为是一个波束。一个波束内可以包括一个或多个天线端口，用于传输数据信道、控制信道和探测信号等。形成一个波束的一个或多个天线端口也可以看作是一个天线端口集。
2、波束配对关系：即，发射波束与接收波束之间的配对关系，也就是空间发射滤波器与空间接收滤波器之间的配对关系。在具有波束配对关系的发射波束和接收波束之间传输信号可以获得较大的波束赋形增益。
在一种实现方式中，发送端和接收端可以通过波束训练来获得波束配对关系。具体地，发送端可通过波束扫描的方式发送参考信号，接收端也可通过波束扫描的方式接收参考信号。具体地，发送端可通过波束赋形的方式在空间形成不同指向性的波束，并可以在多个具有不同指向性的波束上轮询，以通过不同指向性的波束将参考信号发射出去，使得参考信号在发射波束所指向的方向上发射参考信号的功率可以达到最大。接收端也可通过波束赋形的方式在空间形成不同指向性的波束，并可以在多个具有不同指向性的波束上轮询，以通过不同指向性的波束接收参考信号，使得该接收端接收参考信号的功率在接收波束所指向的方向上可以达到最大。
通过遍历各发射波束和接收波束，接收端可基于接收到的参考信号进行信道测量，并将测量得到的结果通过CSI上报发送端。例如，接收端可以将参考信号接收功率(reference signal receiving power，RSRP)较大的部分参考信号资源上报给发送端，如上报参考信号资源的标识，以便发送端在传输数据或信令时采用信道质量较好的波束配对关系来收发信号。
3、参考信号与参考信号资源：参考信号可用于信道测量或者信道估计等。参考信号资源可用于配置参考信号的传输属性，例如，时频资源位置、端口映射关系、功率因子以及扰码等，具体可参考现有技术。发送端设备可基于参考信号资源发送参考信号，接收端设备可基于参考信号资源接收参考信号。
本申请中涉及的信道测量也包括波束测量，即通过测量参考信号获得波束质量信息，用于衡量波束质量的参数包括RSRP，但不限于此。例如，波束质量也可以通过参考信号接收质量(reference signal receiving quality，RSRQ)，信噪比(signal-noise ratio，SNR)，信号与干扰噪声比(signal to interference plus noise ratio，SINR，简称信干噪比)，信道质量指示(channel quality indicator，CQI)等参数衡量。本申请实施例中，为方便说明，在未作出特别说明的情况下，所涉及的信道测量可以视为波束测量。
其中，参考信号例如可以包括信道状态信息参考信号(channel state information reference signal，CSI-RS)、同步信号块(synchronization signal block，SSB)以及探测参考信号(sounding reference signal，SRS)。与此对应地，参考信号资源可以包括CSI-RS 资源(CSI-RS resource)、SSB资源、SRS资源(SRS resource)。
需要说明的是，上述SSB也可以称为同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH block)，所对应的SSB资源也可以称为同步信号/物理广播信道块资源(SS/PBCH block resource)，可简称为SSB resource。
为了区分不同的参考信号资源，每个参考信号资源可对应于一个参考信号资源的标识，例如，CSI-RS资源标识(CSI-RS resource indicator，CRI)、SSB资源标识(SSB resource indicator，SSBRI)、SRS资源索引(SRS resource index，SRI)。
其中，SSB资源标识也可以称为SSB标识(SSB index)。
应理解，上文中列举的参考信号以及相应的参考信号资源仅为示例性说明，不应对本申请构成任何限定，本申请并不排除在未来的协议中定义其他参考信号来实现相同或相似功能的可能。
4、天线端口(antenna port)：简称端口。被接收端设备所识别的发射天线，或者在空间上可以区分的发射天线。针对每个虚拟天线可以配置一个天线端口，每个虚拟天线可以为多个物理天线的加权组合，每个天线端口可以与一个参考信号端口对应。
5、准共址(quasi-co-location，QCL)：或者称准同位。具有QCL关系的天线端口对应的信号中具有相同的参数，或者，一个天线端口的参数可用于确定与该天线端口具有QCL关系的另一个天线端口的参数，或者，两个天线端口具有相同的参数，或者，两个天线端口间的参数差小于某阈值。其中，所述参数可以包括以下一项或多项：时延扩展(delay spread)，多普勒扩展(Doppler spread)，多普勒频移(Doppler shift)，平均时延(average delay)，平均增益，空间接收参数(spatial Rx parameters)。其中，空间接收参数可以包括以下的一项或多项：到达角(angle of arrival，AOA)、平均AOA、AOA扩展、离开角(angle of departure，AOD)、平均离开角AOD、AOD扩展、接收天线空间相关性参数、发送天线空间相关性参数、发射波束、接收波束以及资源标识。
其中，上述角度可以为不同维度的分解值，或不同维度分解值的组合。天线端口为具有不同天线端口编号的天线端口，和/或，具有相同天线端口号在不同时间和/或频率和/或码域资源内进行信息发送或接收的天线端口，和/或，具有不同天线端口号在不同时间和/或频率和/或码域资源内进行信息发送或接收的天线端口。资源标识可以包括：CSI-RS资源标识，或SRS资源标识，或SSB资源标识，或物理随机接入信道(physical random access channel，PRACH)上传输的前导序列的资源标识，或解调参考信号(demodulation reference signal，DMRS)的资源标识，用于指示资源上的波束。
在NR协议中，QCL关系可以基于不同的参数分为以下四种类型：
类型A(type A)：多普勒频移、多普勒扩展、平均时延、时延扩展；
类型B(type B)：多普勒频移、多普勒扩展；
类型C(type C)：多普勒频移、平均时延；以及
类型D(type D)：空间接收参数。
当QCL关系指类型D的QCL关系时，可以认为是空域QCL。当天线端口满足空域QCL关系时，下行信号的端口和下行信号的端口之间，或上行信号的端口和上行信号的端口之间的QCL关系，可以是两个信号具有相同的AOA或AOD，用于表示具有相同的接收波束或发射波束。又例如对于下行信号和上行信号间或上行信号与下行信号的端口间 的QCL关系，可以是两个信号的AOA和AOD具有对应关系，或两个信号的AOD和AOA具有对应关系，即可以利用波束互易性，根据下行接收波束确定上行发射波束，或根据上行发射波束确定下行接收波束。
从发送端来看，如果说两个天线端口是空域QCL的，则可以是指这两个天线端口的对应的波束方向在空间上是一致的。从接收端来看，如果说两个天线端口是空域QCL的，则可以是指接收端能够在同一波束方向上接收到这两个天线端口发送的信号。
具有空域QCL关系的端口上传输的信号还可以具有对应的波束，对应的波束包括以下至少之一：相同的接收波束、相同的发射波束、与接收波束对应的发射波束(对应于有互易的场景)、与发射波束对应的接收波束(对应于有互易的场景)。
具有空域QCL关系的端口上传输的信号还可以理解为使用相同的空间滤波器(spatial filter)接收或发送信号。空间滤波器可以为以下至少之一：预编码，天线端口的权值，天线端口的相位偏转，天线端口的幅度增益。
具有空域QCL关系的端口上传输的信号还可以理解为具有对应的波束对连接(beam pair link，BPL)，对应的BPL包括以下至少之一：相同的下行BPL，相同的上行BPL，与下行BPL对应的上行BPL，与上行BPL对应的下行BPL。
因此，空间接收参数(即，类型D的QCL)可以理解为用于指示接收波束的方向信息的参数。
6、传输配置指示(transmission configuration indicator，TCI)状态：可用于指示两种参考信号之间的QCL关系。每个TCI状态中可以包括服务小区的索引(ServeCellIndex)、带宽部分(band width part，BWP)标识(identifier，ID)和参考信号资源标识，其中，参考信号资源标识例如可以为以下至少一项：非零功率(non-zero power，NZP)CSI-RS参考信号资源标识(NZP-CSI-RS-ResourceId)、非零功率CSI-RS参考信号资源集标识(NZP-CSI-RS-ResourceSetId)、SSB索引(SSB-Index)、追踪参考信号(Tracking Reference Signal，TRS)索引、或相位追踪参考信号索引(Phase Tracking Reference Signal，PTRS)。
其中，服务小区的索引、BWP ID以及参考信号资源标识指的是在波束训练过程中所使用的参考信号资源以及所对应的服务小区和BWP。由于在波束训练过程中，网络设备基于不同的参考信号资源通过不同的发射波束发送参考信号，因此通过不同的发射波束发送的参考信号可以关联不同的参考信号资源；终端设备基于不同的参考信号资源通过不同的接收波束接收参考信号，因此通过不同的接收波束接收的参考信号也可以关联不同的参考信号资源。因此，在波束训练过程中，终端设备可以维护服务小区的索引、BWP ID以及参考信号资源标识与接收波束的对应关系，网络设备可以维护服务小区的索引、BWP ID以及参考信号资源标识与发射波束的对应关系。通过参考信号资源标识，便可以建立接收波束和发射波束之间的配对关系。
在此后的通信过程中，终端设备可以基于网络设备所指示的TCI状态确定接收波束，网络设备可以基于同一TCI状态确定发射波束。
此外，TCI状态可以是全局配置的。在为不同的小区、不同的BWP配置的TCI状态中，若TCI状态的索引相同，则所对应的TCI状态的配置也相同。例如下文中示出的表1和表2中的TCI状态0可以是相同的配置。
7、TCI：可用于指示TCI状态。
在一种实现方式中，网络设备可通过高层信令(如第一RRC信令)为终端设备配置TCI状态(TCI state)列表，该TCI状态列表为用于接收PDSCH的候选TCI状态。例如，网络设备可以通过RRC消息中的TCI状态增加模式列表(tci-States To AddModList)来为终端设备配置TCI状态列表。该TCI状态列表中可以包括多个TCI状态，例如，网络设备可以为每个小区中的每个BWP配置最多128个候选TCI状态，该最多128个候选TCI状态为用于接收PDSCH的候选波束。
此后，在一种可选地实现方式中，网络设备可以通过高层信令(如第一MAC CE信令)激活上述PDSCH的候选TCI状态中的一个或多个TCI状态用于PDSCH的接收。被激活的TCI状态为上述RRC信令(也即第一RRC信令)所配置的TCI状态列表的一个子集。例如，网络设备可以为每个小区中的每个BWP激活最多8个TCI状态。可选地，该一个或多个TCI状态映射至DCI的TCI字域的码点(codepoint)。
在一种可选地实现方式中，网络设备可以通过高层信令(如第二RRC信令)为终端设备配置TCI状态(TCI state)列表，该TCI状态列表为用于接收PDCCH的(候选)TCI状态。该第二RRC信令指示上述PDSCH的TCI状态列表中的一个或多个TCI状态用于PDCCH的接收。该第二RRC信令指示的一个或多个TCI状态为上述第一RRC信令所配置的TCI状态列表的一个子集。例如，网络设备可以为每个小区中的每个BWP指示最多64个TCI状态。可选地，该TCI状态用于接收PDCCH。
在一种可选地实现方式中，网络设备可以通过高层信令(如第二MAC-CE信令)指示上述PDCCH的TCI状态列表中的一个或多个TCI状态用于PDCCH的接收。该第二MAC-CE信令指示的一个或多个TCI状态为上述第二RRC信令所配置的TCI状态列表的一个子集。

图2是从设备交互的角度示出的传输信号的方法200的示意性流程图。如图所示，图2中示出的方法200可以包括步骤201至步骤203。下面结合图2详细说明方法200中的各个步骤。
在步骤201中，终端设备确定至少两个第一参考信号资源。
具体而言，终端设备确定至少两个参考信号资源(例如，至少两个第一参考信号资源)，该至少两个第一参考信号资源可以用于终端设备接收网络设备下发的物理下行共享信道(physical downlink shared channel，PDSCH)。

假设DMRS-type的取值为1，此时协议中预定义的DMRS port所属的CDM group的分组情况为：CDM group#0中包括的DMRS port为DMRS port#0、DMRS port#1、DMRS port#4、DMRS port#5，CDM group#1中包括的DMRS port为DMRS port#2、DMRS port#3、DMRS port#6、DMRS port#7。
终端设备在确定解调第一信道的目标参考信号资源时，可以将索引值较小的CDM group与索引值较小的第二参考信号资源对应，将索引值较大的CDM group与索引值较大的第二参考信号资源对应，例如，终端设备将CDM group#0与索引值为#3的第二参考信号资源对应，即将索引值为#3的第二参考信号资源确定为解调DMRS port#0、DMRS port#1时使用的目标参考信号资源，终端设备将CDM group#1与索引值为#5的第二参考信号资源对应，即将索引值为#5的第二参考信号资源确定为解调DMRS port#6～DMRS port#7时使用的目标参考信号资源，最终完成对第一信道的解调。
此外，终端设备在对第一信道进行解调时，可以根据关联关系，将与所述第一信息存在关联关系的至少一个参考信号资源确定为所述目标参考信号资源，所述关联关系用于指示多个参考信号资源与多个第二信息之间的关联关系，所述第二信息包括以下至少一种信息：天线端口的索引号、天线端口所属的码分复用天线端口组的索引号、承载DCI的资源所属的控制资源集合CORESET的索引号与承载DCI的资源所属的搜索空间集合的索引号，所述第一信息为所述多个第二信息中的一种。
例如，该关联关系中指示了多个参考信号资源与多个第二信息(例如，CDM group的索引值)之间的关联关系，该关联关系指示CDM group#0与索引值为#4的参考信号资源对应，CDM group#1与索引值为#6的参考信号资源对应。
例如，终端设备接收到的DCI#1中携带的DMRS port字域的取值为1，DMRS port字域的取值1所指示的DMRS port包括DMRS port#4～DMRS port#5，终端设备接收到的DCI#2中携带的DMRS port字域的取值为2，DMRS port字域的取值2所指示的DMRS port包括DMRS port#2～DMRS port#3。
假设DMRS-type的取值为1，此时协议中预定义的DMRS port所属的CDM group的分组情况为：CDM group#0中包括的DMRS port为DMRS port#0、DMRS port#1、DMRS port#4、DMRS port#5，CDM group#1中包括的DMRS port为DMRS port#2、DMRS port#3、DMRS port#6、DMRS port#7。
终端设备在确定解调第一信道的目标参考信号资源时，可以将CDM group#0与索引值为#4的第二参考信号资源对应，即将索引值为#4的第二参考信号资源确定为解调DMRS  port#4～DMRS port#5时使用的目标参考信号资源，将CDM group#1与索引值为#6的第二参考信号资源对应，即将索引值为#6的第二参考信号资源确定为解调DMRS port#2～DMRS port#3时使用的目标参考信号资源，最终完成对第一信道的解调。
此外，该关联关系中指示了多个参考信号资源与多个第二信息(例如，调度第一信道的DCI所在的搜索空间集合的索引号)之间的关联关系，该关联关系指示搜索空间集合#1与索引值为#5的参考信号资源对应，搜索空间集合#2与索引值为#7的参考信号资源对应。
例如，终端设备接收到的DCI#1所在的搜索空间集合的索引号为#1，终端设备接收到的DCI#2中携带的所在的搜索空间集合的索引号为#2。
终端设备在确定解调第一信道的目标参考信号资源时，可以将搜索空间集合#1与索引值为#5的第二参考信号资源对应，即将索引值为#5的第二参考信号资源确定为解调数据#1对应的DMRS port时使用的目标参考信号资源，将搜索空间集合#2与索引值为#7的第二参考信号资源对应，即将索引值为#7的第二参考信号资源确定为解调数据#2对应的DMRS port时使用的目标参考信号资源，最终完成对第一信道的解调。
此外，终端设备还可以根据DCI调度的第一信道所在的时域资源位置确定解调第一信道的目标参考信号资源。
例如，第一信道所在的时域资源位置为时隙(slot)#1，终端设备可以确定slot#1中是否存在CORESET，若slot#1中存在CORESET，则终端设备可以将slot#1中包括的索引值最小的CORESET对应的参考信号资源确定为目标参考信号资源。例如，slot#1中包括的CORESET为CORESET#0～CORESET#3，则终端设备可以将CORESET#0对应的参考信号资源确定为目标参考信号资源。
若slot#1中不存在CORESET，则终端设备可以将距离slot#1最近的slot中包括的索引值最小的CORESET对应的参考信号资源确定为目标参考信号资源。例如，终端设备将距离slot#1最近的slot#0中的索引值最小的CORESET对应的参考信号资源确定为目标参考信号资源。例如，终端设备将slot#0包括的CORESET为CORESET#1～CORESET#3，则终端设备可以将CORESET#1对应的参考信号资源确定为目标参考信号资源。
其中，上述的CORESET对应的参考信号资源可以是与该CORESET存在关联关系的CORESET，或者，可以是默认的CORESET，本申请对此不作限定。
需要说明的是，针对场景2，该多个数据可以是多个TRP同时发送的，或者，该多个数据可以是多个TRP依次分时发送的。当多个数据可以是多个TRP同时发送的时，即承载该多个数据的时域资源是至少部分重叠的，此时，终端设备在确定解调第一信道的目标参考信号资源时，需要保证与不同DCI对应的目标参考信号资源是能够被终端设备同时接收到的参考资源。
作为另一种实现方式，终端设备在对第一信道进行解调时，可以根据第一信息，在至少两个第一参考信号资源中确定至少一个参考信号资源为目标参考信号资源，第一信息是调度第一信道的DCI的相关信息；根据所述目标参考信号资源，解调所述第一信道。
终端设备可以从至少两个第一参考信号资源中确定目标参考信号资源，根据该目标参考信号资源，解调所述第一信道。关于终端设备根据从至少两个第一参考信号资源中确定的目标参考信号资源解调第一信道的方法，请参考场景2中的终端设备根据从至少两个第二参考信号资源中确定的目标参考信号资源解调第一信道中的相关描述，为了简洁，此处 不再赘述。
场景3，DPS场景。
所谓DPS，例如可以是指在第一时刻DCI#1调度的数据来自TRP#1，在第二时刻DCI#2调度的数据来自TRP#2。
更具体地，例如，可以是在第一时刻，该数据是TRP#1发送的，在第二时刻，该数据是TRP#2发送的。。

假设DMRS-type的取值为1，此时协议中预定义的DMRS port所属的CDM group的分组情况为：CDM group#0中包括的DMRS port为DMRS port#0、DMRS port#1、DMRS port#4、DMRS port#5，CDM group#1中包括的DMRS port为DMRS port#2、DMRS port#3、DMRS port#6、DMRS port#7。
终端设备在确定解调第一信道的目标参考信号资源时，可以将索引值较小的CDM group与索引值较小的第二参考信号资源对应，将索引值较大的CDM group与索引值较大的第二参考信号资源对应，例如，终端设备将CDM group#0与索引值为#4的第二参考信号资源对应，即将索引值为#4的第二参考信号资源确定为解调DMRS port#4、DMRS port#5时使用的目标参考信号资源，终端设备将CDM group#1与索引值为#6的第二参考信号资源对应，即将索引值为#6的第二参考信号资源确定为解调DMRS port#6～DMRS port#7时使用的目标参考信号资源，最终完成对第一信道的解调。

假设DMRS-type的取值为1，此时协议中预定义的DMRS port所属的CDM group的分组情况为：CDM group#0中包括的DMRS port为DMRS port#0、DMRS port#1、DMRS port#4、DMRS port#5，CDM group#1中包括的DMRS port为DMRS port#2、DMRS port#3、DMRS port#6、DMRS port#7。

此外，该关联关系中指示了多个参考信号资源与多个第二信息(例如，调度第一信道的DCI所在的搜索空间集合的索引号)之间的关联关系，该关联关系指示搜索空间集合#1与索引值为#5的参考信号资源对应，搜索空间集合#2与索引值为#7的参考信号资源对应。
例如，终端设备接收到的DCI#1所在的搜索空间集合的索引号为#1，终端设备接收到的DCI#2中携带的所在的搜索空间集合的索引号为#2。
终端设备在确定解调第一信道的目标参考信号资源时，可以将搜索空间集合#1与索引值为#5的第二参考信号资源对应，即将索引值为#5的第二参考信号资源确定为解调数据#1对应的DMRS port时使用的目标参考信号资源，将搜索空间集合#2与索引值为#7的第二参考信号资源对应，即将索引值为#7的第二参考信号资源确定为解调数据#2对应的DMRS port时使用的目标参考信号资源，最终完成对第一信道的解调。
作为另一种实现方式，终端设备在对第一信道进行解调时，可以根据第一信息，在至少两个第一参考信号资源中确定至少一个参考信号资源为目标参考信号资源，第一信息是调度第一信道的DCI的相关信息；根据所述目标参考信号资源，解调所述第一信道。
终端设备可以从至少两个第一参考信号资源中确定目标参考信号资源，根据该目标参考信号资源，解调所述第一信道。关于终端设备根据从至少两个第一参考信号资源中确定的目标参考信号资源解调第一信道的方法，请参考场景2中的终端设备根据从至少两个第二参考信号资源中确定的目标参考信号资源解调第一信道中的相关描述，为了简洁，此处不再赘述。
还需要说明的是，本申请中的技术方案还可以应用在单TRP的场景，网络设备使用不同的参考信号资源对应的空间相关参数同时发送多个数据的场景中，具体实现请参考前面相关描述，为了简洁，此处不再赘述。
还需要说明的是，本申请中的关联关系可以是TRP配置的，还可以是协议预定义的。该关联关系可以是直接的关联关系，也可以是间接的关联关系。其中，间接的关联关系可以是指通过其他的一个或多个中间量获得用于解调的目标参考信号资源与DMRS port的关联关系。该中间量例如可以是TRP ID或小区(cell)ID。
应理解，本发明中的上述方法，也可以用至上行PUSCH的波束指示方法或空间相关信息的指示方法。相应的，此时TCI字域替换为SRI字域，TCI state/QCL替换为SpatialRelationInfo/SpatialRelationInfo，TCI state/QCL指示的参考信号替换为SpatialRelationInfo/SpatialRelationInfo指示的参考信号。
可选地，在multi-TRP场景下，一个DCI调度的一份PDSCH可能来自一个TRP或多个TRP。一种可能的实现方式中，该PDSCH是来自一个TRP还是两个TRP是由该DCI中的TCI field确定的。
应理解，根据调度所述第一信道的DCI中携带的传输配置指示字域，在所述至少两个第一参考信号资源中确定至少一个参考信号资源为目标参考信号资源。一种可能的实施方式为，根据调度所述第一信道的DCI中携带的传输配置指示字域指示的TCI状态的个数(或者根据DCI传输配置指示字域的所有候选码点中每个码点指示的TCI状态的最大个数)，在所述至少两个第一参考信号资源中确定至少一个参考信号资源为目标参考信号资源。另一种可能的实施方式为，根据调度所述第一信道的DCI中携带的传输配置指示字域指示的TCI状态的个数以及TCI状态是否相同，在所述至少两个第一参考信号资源中确定至少一个参考信号资源为目标参考信号资源。
应理解，或者根据调度所述第一信道的DCI中携带的传输配置指示字域，在所述至少两个第二参考信号资源中确定至少一个参考信号资源为目标参考信号资源。一种可能的实施方式为，根据调度所述第一信道的DCI中携带的传输配置指示字域指示的TCI状态的个数(或者根据DCI传输配置指示字域的所有候选码点中每个码点指示的TCI状态的最大个数)，在所述至少两个第二参考信号资源中确定至少一个参考信号资源为目标参考信号资源。另一种可能的实施方式为，根据调度所述第一信道的DCI中携带的传输配置指示字域指示的TCI状态的个数以及TCI状态是否相同，在所述至少两个第二参考信号资源中确定至少一个参考信号资源为目标参考信号资源。
应理解，下面的实施例或实现方式中，“在所述至少两个第二参考信号资源中确定至少一个参考信号资源为目标参考信号资源”，也可以是“在默认的两个传输配置指示状态中确定至少一个传输配置指示状态指示的参考信号资源为目标参考信号资源”，或者还可以是“在所述至少两个第一参考信号资源中确定至少一个参考信号资源为目标参考信号资源”。
本申请实施例中可以定义默认的两个TCI state，该两个TCI state指示的type D QCL信息(可以指示前文中的至少两个第一参考信号资源)缓存数据。当DCI解码完成后，可以使用该两个TCI state指示的type A/B/C QCL信息(可以指示前文中的至少两个第二参考信号资源)中的至少一种解调PDSCH。
也就是说PDSCH DMRS port的type D QCL信息可以是默认的两个TCI state中指示的type D QCL信息，PDSCH DMRS port的tyep A/B/C QCL信息可以是根据调度PDSCH的DCI中包含的TCI field的指示值确定的。
应理解，上述两个default TCI state可以是：第一个TCI state和第二个TCI state。第一个TCI state和第二个TCI state的实现方式有多种。
例如，第一个TCI state可以是最近的时隙中标识最小的CORESET的TCI state，第二个TCI state可以是激活的TCI state中的type D QCL RS与在最近的时隙中标识最小的CORESET的TCI state中的type D QCL RS。这两个参考信号资源(两个TCI state对应的type D QCL RS)是可以是一起分组上报，分组上报的这两个参考信号资源是可以被终端设备同时接收的参考信号资源。
又如，第一个TCI state是最近的时隙中标识最小的CORESET的TCI state；第二个TCI state是由MAC CE激活并与第一个TCI state配对的TCI state。
又如，DCI的传输配置指示字域的所有码点中，指示两个TCI state的码点中的码点值最小的码点所指示的两个TCI状态。
应理解，确定两个TCI state还可以有其他方式，本申请对此不做限定。
在一种可能的实现方式中，根据调度所述第一信道的DCI中携带的传输配置指示字域，在所述至少两个第二参考信号资源中确定至少一个参考信号资源为目标参考信号资源，包括：
当所述传输配置指示字域指示的传输配置指示状态(TCI state)个数为1时，确定所述至少两个第二参考信号资源中的第一个第二参考信号资源作为目标参考信号资源；
当所述传输配置指示字域指示的传输配置指示状态(TCI state)个数为2个时，确定所述至少两个第二参考信号资源中的两个第二参考信号资源作为目标参考信号资源。
一种可能的实现方式中，当调度偏移值小于或等于预设的阈值时，终端设备可以确定两个TCI state。并假设第一信道或第一信道的DMRS port的type D QCL与该两个TCI state中指示的type D QCL信息相同。并根据调度所述第一信道的DCI中携带的TCI字域的取值，或，所述第一信道的DCI中携带的TCI字域指示的TCI state的个数，在所述两个TCI state中确定第一信道的type A、type B、type C QCL信息的一种。
可选地，当一个DCI用于调度多TRP，且TCI字域存在，且scheduling offset<K时，根据根据调度PDSCH的DCI中的TCI字域确定解调PDSCH的type A/B/C的QCL信息。下面对该过程进行详细描述。
1.确定两个default TCI state中的两个type D QCL用于接收scheduling offset<K的PDSCH。
2.根据调度PDSCH的DCI中的TCI field信息确定两个default TCI state中的至少一个TCI state指示的type A/B/C QCL用于解调该PDSCH。
应理解，当TCI field信息指示TCI state个数为1个时，可以根据default TCI state中的第一个TCI state指示的type A/B/C QCL解调该PDSCH。当TCI field信息指示TCI state个数为2个时，可以根据default TCI state中的两个TCI state指示的type A/B/C QCL解调该PDSCH。
例如，UE确定default TCI state是TCI n1{type A RS a1，type D RS b1}+TCI m1{type A RS c1，type D RS d1}。调度PDSCH的DCI指示的TCI field值为001，也即DCI指示TCI n2(type A RS a2，type D RS b2}。那么UE根据TCI n1指示的{type A RS a1)解调PDSCH。
在另一种可能的实现方式中，根据调度所述第一信道的DCI中携带的天线端口字域，在所述至少两个第二参考信号资源中确定至少一个参考信号资源为目标参考信号资源，包括：
当所述天线端口字域指示的DMRS port所属的CDM group个数为1时，确定所述至少两个第二参考信号资源中的第一个第二参考信号资源作为目标参考信号资源；
当所述天线端口字域指示的DMRS port所属的CDM group个数为2(或3)时，确定所述至少两个第二参考信号资源中的两个第二参考信号资源作为目标参考信号资源。
在另一种可能的实现方式中，根据调度所述第一信道的DCI中携带的天线端口字域和传输配置指示字域，在所述至少两个第二参考信号资源中确定至少一个参考信号资源为目标参考信号资源，包括：
当所述天线端口字域指示的DMRS port所属的CDM group个数为1，且传输配置指示字域指示的传输配置指示状态(TCI state)个数为1时，确定所述至少两个二参考信号资源中的第一个第二参考信号资源作为目标参考信号资源；
当所述天线端口字域指示的DMRS port所属的CDM group个数为1，且传输配置指示字域指示的传输配置指示状态(TCI state)个数为2时，确定所述至少两个第二参考信号资源中的两个第二参考信号资源作为目标参考信号资源。
在另一种可能的实现方式中，根据所述重复次数指示信息指示的所述第一信道的重复次数，确定所述目标参考信号资源。例如，重复次数指示信息指示的重复次数为N，则当前调度包括N个第一信道，或者是N个时频资源，每个第一信道或者每个时频资源用于承载相同的传输块(Transmission Block，TB)。
在另一种可能的实现方式中，根据调度所述第一信道的DCI中携带的重复次数指示信息和传输配置指示字域，在所述至少两个第二参考信号资源中确定至少一个参考信号资源为目标参考信号资源，包括：
当所述重复次数指示信息指示的重复次数为1或者为缺省状态，且传输配置指示字域指示的传输配置指示状态(TCI state)个数为1时，确定所述至少两个第二参考信号资源中的第一个第二参考信号资源作为目标参考信号资源；
当所述重复次数指示信息指示的重复次数为1或者为缺省状态，且传输配置指示字域指示的传输配置指示状态(TCI state)个数为2时，确定所述至少两个第二参考信号资源中的两个第二参考信号资源作为目标参考信号资源；
当所述重复次数指示信息指示的重复次数大于等于2，且传输配置指示字域指示的传输配置指示状态(TCI state)个数为2时，确定所述至少两个第二参考信号资源中的两个第二参考信号资源作为目标参考信号资源。
在另一种可能的实现方式中，根据传输机制指示信息和调度所述第一信道的DCI中携带传输配置指示字域，在所述至少两个第二参考信号资源中确定至少二个参考信号资源为目标参考信号资源，包括：
当所述传输机制指示信息指示为重复传输，且传输配置指示字域指示的传输配置指示状态(TCI state)个数为2时，确定第二信道中的参考信号资源作为目标参考信号资源；
当所述传输机制指示信息不指示为重复传输，且传输配置指示字域指示的传输配置指示状态(TCI state)个数为2时，确定第二信道中的参考信号资源作为目标参考信号资源。
可选的，所述传输机制指示信息中指示的重复传输是指，由调度所述第一信道的DCI指示的两个频域资源块分别对应不同的TCI状态；
可选的，两个频域资源块承载相同的TB；
可选的，不同的TCI状态为上述默认的两个TCI状态；
可选的，所述传输机制指示信息中指示的重复传输是指，两个TCI状态分别对应由调度所述第一信道的DCI指示的两个时域资源块；
可选的，两个时域资源块承载相同的TB；
可选的，两个时域资源块位于同一个时隙slot内。
上述技术方案中，可以应用在multi-TRP场景下，当scheduling offset小于预设门限时，终端设备解码出DCI，可以获知该份PDSCH是单TRP传输还是多TRP传输的数据，从而可以确定PDSCH的DMRS端口与TCI state或QCL信息之间的对应关系。
应理解，本申请各实施例，还可以应用在其他场景。例如，多个DCI可能在不同时刻或同一时刻调度来自不同TRP的PDSCH。当scheduling offset小于预设门限时，终端设备可以根据当前DCI所在的CORESET的索引号确定该DCI调度的PDSCH的TCI state或QCL信息。例如：确定与该CORESET关联的CORESET中索引最小的CORESET的TCI state，作为该PDSCH的TCI state；或者确定与该CORESET关联的CORESET中的，离该DCI最近的时隙中的，CORESET索引最小的CORESET的TCI state，作为该PDSCH的TCI state。
