Description

一种信号传输的指示方法和通信装置 技术领域
本申请涉及无线通信领域，并且更具体地，涉及一种信号传输的指示方法和通信装置。
背景技术
在新无线接入技术(new radio access technology，NR)中，预编码技术(precoding)是多输入输出(multiple input multiple output，MIMO)的关键技术之一。具有相同预编码矩阵的连续资源块(Resource block，RB)称为预编码资源块组(Precoding Resource Block Group，PRG)。而PRG的大小(PRG size)是由物理资源块(physical resource block，PRB)绑定(physical resource block bundling，PRB bundling)流程确定的。PRB绑定是将连续的多个PRB绑定在一起联合处理，网络设备可以对该多个PRB采用相同预处理方式(包括波束赋形和预编码)，终端设备可以联合该多个PRB进行信道估计。终端设备基于多个PRB进行联合信道估计时，利用连续频域资源之间的信道相关性，可以提高信道估计的准确性。然而，当前协议中仅支持的PRG大小为2资源块(resource block，RB)、4RB或全带宽。
因此，亟需提出一种支持更精细化的预编码频域粒度的技术，进一步适应信道频选特性，提升下行权值准确性，进而提升基站的下行容量。
发明内容

应理解，该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或可设置于该设备的芯片，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、传输点(transmission point，TP)或者发送接收点(TRP)等，还可以为5G、6G甚至未来系统中使用的设备，如NR，系统中的gNB，或，传输点(TRP或TP)，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)，或微微基站(Picocell)，或毫微微基站(Femtocell)，或，车联网(vehicle to everything，V2X)或者智能驾驶场景中的路侧单元(road side unit，RSU)等。网络设备还可以为D2D、V2X或M2M中承载基站功能的设备等，本申请对网络设备的具体类型不作限定。可理解，在不同的无线接入技术的系统中，具备网络设备功能的设备的名称可能会有所不同。
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)层，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)层和物理层(physical layer，PHY)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层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU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RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，在此不做限制。
本申请公开的实施例中，用于实现网络设备的功能的装置可以是网络设备；也可以是能够支持网络设备实现该功能的装置，例如芯片系统，该装置可以被安装在网络设备中。
在本申请公开的实施例中，以用于实现网络设备的功能的装置是网络设备，以网络设备是基站为例，描述本申请公开的实施例提供的技术方案。
还应理解，该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、前述的V2X车联网中的无线终端或无线终端类型的RSU等等。本申请的实施例对应用场景不做限定。
作为示例而非限定，在本发明实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，为了便于理解本申请实施例，作出以下几点说明。
第一，在本申请实施例中，“指示”可以包括直接指示和间接指示，也可以包括显式指示和隐式指示。将某一信息(如下文所述的配置信息)所指示的信息称为待指示信息，则具体实现过程中，对待指示信息进行指示的方式有很多种，例如但不限于，可以直接指示待指示信息，如待指示信息本身或者该待指示信息的索引等。也可以通过指示其他信息来间接指示待指示信息，其中该其他信息与待指示信息之间存在关联关系。还可以仅仅指示待指示信息的一部分，而待指示信息的其他部分则是已知的或者提前约定的。例如，还可以借助预先约定(例如协议规定)的各个信息的排列顺序来实现对特定信息的指示，从而在一定程度上降低指示开销。
第二，在下文示出的实施例中，部分场景以无线通信网络中NR网络的场景为例进行说明，应当指出的是，本申请公开的实施例中的方案还可以应用于其他无线通信网络中，相应的名称也可以用其他无线通信网络中的对应功能的名称进行替代。
第三，在下文示出的实施例中，第一、第二以及各种数字编号仅为描述方便进行的区分。在下文示出的实施例中，对于一种技术特征，通过“第一”、“第二”、“第三”等区分该种技术特征中的技术特征，该“第一”、“第二”、“第三”描述的技术特征间无先后顺序或者大小顺序。并不用来限制本申请实施例的范围。例如，区分不同的指示信息、不同的波束、不同的面板等。
第四，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a、b和c中的至少一项(个)，可以表示：a，或b，或c，或a和b，或a和c，或b和c，或a、b和c，其中a，b，c可以是单个，也可以是多个。

第六，本申请公开的实施例中，“的(of)”，“相应的(relevant)”和“对应的(corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。
第七，在下文示出的实施例中，“预定义”可以为通过协议定义，可以通过在设备(例如，包括终端设备和网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现，本申请对于其具体的实现方式不做限定。
为便于理解本申请实施例，首先对本申请中涉及的几个术语做简单说明。
1、预编码资源块组(Precoding resource block group，PRG)
NR协议中定义的下行预编码频域粒度，一组下行预编码粒度称为预编码资源块组。当前NR协议可以指示的目标预编码粒度包括n2、n4和全带宽(wideband，WB)预编码粒度，即当前协议支持的采用相同预编码权值矩阵的频域粒度分别为2RB、4RB以及WB。终端设备可以假定预编码频域粒度为连续的x个RB，其中x可指定为{n2，n4，WB}中的一个值。示例性的，如果x被指定为WB，终端设备则只在连续的RB上被调度，且UE假定在所有被分配的频域资源上使用同样的预编码矩阵。如果x被指定为n2，终端设备则在连续的2RB上被调度，且UE假定在连续的2RB上使用同样的预编码矩阵。如果x被指定为n4，终端设备则在连续的4RB上被调度，且UE假定在连续的4RB上使用同样的预编码矩阵。
本申请实施例中，预编码资源块组的大小(Precoding resource block group size，PRG size)是由物理资源块绑定(physical resource block bundling，PRB bundling)确定的，在不同通信设备侧资源绑定的叫法可能不同，但其含义可以相同。例如，通常在发送端(例如，网络设备)侧资源绑定粒度称为PRG，且发送端在同一PRG中传输的数据采用相同的预编码；在接收端(例如，终端设备)侧资源绑定粒度称为PRG，且发送端在同一PRG中传输的数据采用相同的预编码，且接收端对同一PRG中传输的数据进行联合信道估计。
需要说明的是，例如，发送端侧和接收端侧的资源绑定粒度均可以指PRG，或者，发送端侧和接收端侧的资源绑定均可以指PRB bundling，本申请实施例并不限于此。
应理解，网络设备侧的PRG可以与终端设备侧的PRB bundling相对应。针对同一个资源绑定粒度取值，网络设备侧确定PRG的方法和终端设备侧确定PRB bundling的方法可以相同。但在同一侧，即在网络设备侧或终端设备侧，资源绑定粒度取值为第一目标值和第二目标值时对应的确定PRG的方法或PRB bundling的方法不同。
2、预编码粒度n1
预编码粒度n1为小于2RB的预编码粒度。
在本申请实施例中，为了提供更加精细化的预编码频域粒度，新增了预编码粒度集合包括小于2RB的预编码粒度，并将其定义为n1。其中，n1例如但不限于，可以为0.5RB、1RB或1.5RB的预编码粒度。本申请实施例中以n1为1RB进行示例性说明。
其中，n1/wideband(n1/WB)字段为新增的指示字段。示例性的，以n1为1RB为例，对n1/WB字段进行释义，对于支持1RB预编码粒度的终端设备，网络设备通过向终端设备发送指示信息，指示信息指示终端设备下行预编码粒度为1RB；对于不支持1RB预编码粒度的终端设备，网络设备通过指示信息指示终端设备下行预编码粒度为WB。n1-wideband，
可以理解的，n1/WB仅仅为示例，也可以表示为n1-wideband，还可以定义其它新的字段， 本申请实施例对此不作限定。例如但不限于，n1/n4，以n1为1RB为例，对于支持1RB预编码粒度的终端设备，网络设备通过向终端设备发送指示信息，指示信息指示终端设备下行预编码粒度为1RB；对于不支持1RB预编码粒度的终端设备，网络设备通过指示信息指示终端设备下行预编码粒度为4RB。n1/n2，以n1为1RB为例，对于支持1RB预编码粒度的终端设备，网络设备通过向终端设备发送指示信息，指示信息指示终端设备下行预编码粒度为1RB；对于不支持1RB预编码粒度的终端设备，网络设备通过指示信息指示终端设备下行预编码粒度为2RB。
为便于理解本申请实施例，下面以图1示出的通信系统为例详细说明适用于本申请实施例提供的信号传输的指示方法的通信系统。图1示出了适用于本申请实施例的信号传输的指示方法的通信系统100的示意图。如图1所示，该通信系统100可以包括至少一个终端设备，如图中所示的终端设备101，也可以为配置于该终端设备中的芯片；该通信系统100还可以包括至少一个网络设备，如图中所示的网络设备#1 102或网络设备#2 103，也可以为配置于该网络设备中的芯片。
可选地，该通信系统100可以包括一个或多个网络设备，如图中所示的网络设备#1 102和网络设备#2 103。该网络设备#1 102和网络设备#2 103可以是同一个小区中的网络设备，也可以是不同小区中的网络设备，本申请对此不作限定。图中仅为示例，示出了网络设备#1 102和网络设备#2 103位于同一个小区中的示例。
以下，不失一般性，以终端设备与网络设备之间的交互过程为例详细说明本申请实施例提供的信号传输方法。
目前，在新无线接入技术(new radio access technology，NR)中，预编码技术(precoding)是多输入输出(multiple input multiple output，MIMO)的关键技术之一。具有相同预编码矩阵的连续资源块(Resource block，RB)称为预编码资源块组(Precoding Resource Block Group，PRG)。而PRG的大小(PRG size)是由物理资源块捆绑(Physical Resource block bundling，PRB bundling)流程决定的，PRG越小，预编码矩阵与相应的信道矩阵匹配度越高，适应信道频选能力越强。
在NR相关协议中，物理资源块捆绑(Physical Resource block bundling，PRB bundling)流程可以被配置为静态指示方式和动态指示方式。当高层参数被配置为静态指示时，该高层参数可以是prb-BundlingType，则PRG size为通过高层参数bundleSize指示的单个值。当高层参数prb-BundlingType被配置为动态指示时，PRG size通过预编码粒度集合bundleSizeSet1和预编码粒度集合bundleSizeSet2联合指示，其中，bundleSizeSet1中PRG size的取值集合可以为{n4，wideband，n2-wideband，n4-wideband}，共计4种选择，bundleSizeSet2中PRG size的取值集合可以为{n4，wideband}，共计2种选择。在bundleSizeSet1或bundleSizeSet2的取值中确定PRG size。高层参数prb-BundlingType的协议具体定义如下：
Figure PCTCN2020119700-appb-000001
Figure PCTCN2020119700-appb-000002
上述通过bundleSizeSet1和bundleSizeSet2联合指示确定PRG size，能够动态指示的PRG size组合一共有八种情况。如表1所示，Set1和Set2分别对应协议中的bundleSizeSet1和bundleSizeSet2。示例性的，当Set1指示4RB时，Set2可以指示4RB或WB；当Set1指示WB时，Set2可以指示4RB或WB。由此可以看出，在表1前4种状态中，实际有效的PRG size指示状态只包括4RB或WB。
表1
编号 Set 1 Set 2
1 4 4
2 4 WB
3 WB 4
4 WB WB
5 n2-WB 4
6 n2-WB WB
7 n4-WB 4
8 n4-WB WB
由此可见，当前NR协议中，存在较多的冗余指示位，且支持的PRG size有限，仅为2RB、4RB或WB，不支持更精细的预编码粒度。因此，亟需提出一种支持更精细的预编码粒度的解决方案。
有鉴于此，本申请实施例提供一种信号传输的指示方法，能够支持更精细的预编码粒度，从而有利于多用户(Multi-User)多输入输出(Multi-input Multi-output，MIMO)中不同配对用户间的干扰抑制，使得用户间干扰进一步降低；同时，更精细的频域粒度能够更好地适配信道的频选特性，增加可配对的最高流数。在本申请实施例中，通过利用现有协议中存在冗余指示位，指示更为丰富的PRG size取值组合，支持更灵活的动态PRB bundling选择过程。
以下结合图2阐述本申请实施例提供的信号传输的指示方法。需要说明的是，本申请提供的通信方法可以应用于无线通信系统中，例如，图1中所示的通信系统100中。处于通信系统中的通信装置之间可具有无线通信连接关系。例如，图1中所示的终端设备101分别可以与网络设备#1 102和网络设备#2 103之间具有无线通信连接关系，本申请对此不作限定。
请参阅图2，图2是从设备交互的角度示出的本申请实施例提供的信号传输的指示方法200 的示意性流程图。如图2所示，图2中示出的方法200可以包括步骤210至步骤230。下面结合附图对方法200中的各个步骤做详细说明。
步骤210，终端设备接收第一指示信息。对应地，网络设备发送第一指示信息。
上述步骤210，也可以理解为：网络设备向终端设备发送第一指示信息，终端设备接收来自网络设备的第一指示信息。
其中，该第一指示信息用于指示至少一个目标值，该目标值对应至少一个预编码粒度，该目标值根据预编码粒度集合确定，该预编码粒度集合中包括小于2资源块RB的预编码粒度。
示例性的，第一指示信息可以为bundleSize，此时高层参数(prb-BundlingType)被配置为静态指示(staticBundling)；第一指示信息也可以为bundleSizeSet1和bundleSizeSet2，此时高层参数(prb-BundlingType)被配置为动态指示(dynamicBundling)。可以理解的，上述第一指示信息仅为示例，该第一指示信息还可以携带在，例如但不限于，无线资源控制(radio resource control，RRC)消息、媒体接入控制元素(Media access control element，MAC-CE)和下行控制信令(Downlink control information，DCI)中的一项或多项中。该第一指示信息也可以携带在新增的信令中。应理解，RRC消息、MAC-CE和DCI仅为便于理解而示例，不应对本申请构成任何限定。本申请并不排除采用其他信令来携带指示信息的可能，也不排除对上述信令定义其他名称的可能。换句话说，该第一指示信息可以携带在物理层信令和高层信令的一项或多项中。本申请对此不作限定。
可选的，预编码粒度集合包括第一集合和第二集合。
一种可能的实施方式，第一集合包括：1RB、2RB、4RB和全带宽，第二集合包括：2RB和全带宽。示例性的，第一集合记为A1，第二集合记为A2，即A1为{n4，n1/wideband，n2-wideband，n4-wideband}，A2为{n4，wideband}。
另一种可能的实施方式，第一集合包括：2RB、4RB和全带宽，第二集合包括：1RB、4RB和全带宽。示例性的，第一集合记为A1，第二集合记为A2，即A1为{n4，n2，n2-wideband，n4-wideband}，A2为{n1-n4，n1-wideband}。
另一种可能的实施方式，第一集合包括：1RB、2RB、4RB和全带宽，第二集合包括：1RB、4RB和全带宽。示例性的，第一集合记为A1，第二集合记为A2，即A1为{n4，n2-n1，n2-wideband，n4-wideband}，A2为{n1-n4，n1-wideband}。
可以理解的，上述A1为第一指示信息为bundleSizeSet1时对应的目标值集合，且bundleSizeSet1指示A1中的一个目标值；A2为第一指示信息为bundleSizeSet2时对应的目标值集合，且bundleSizeSet2指示A2中的一个目标值。且上述给出的第一集合和第二集合包含的预编码粒度仅为便于描述而给出的示例，本申请实施例对此不作限定。本申请实施例中所定义的集合，只要第一集合和第二集合任一集合中包括小于2RB的预编码粒度，或第一集合和第二集合均包括小于2RB的预编码粒度，均在本申请实施例所保护的范围。
可选的，在本申请实施例中，可以通过bundleSizeSet1和bundleSizeSet2联合指示确定目标预编码粒度PRG size。
以下以A1为{n4，n1/wideband，n2-wideband，n4-wideband}，A2为{n4，wideband}为例，对本申请实施例进行示例性说明。其中，A1为第一指示信息为bundleSizeSet1时对应的目标值集合，且bundleSizeSet1指示A1中的一个目标值；A2为第一指示信息为bundleSizeSet2 时对应的目标值集合，且bundleSizeSet2指示A2中的一个目标值；n1/wideband的释义在上述术语解释中已详细说明，此处不再赘述。这里对n2-wideband和n4-wideband进行示例性说明，n2-wideband为预编码粒度取值为n2或wideband，n4-wideband为预编码粒度取值为n4或wideband。上述Set1和Set2对应prb-Bundling Type配置参数可以定义为如下所示：
Figure PCTCN2020119700-appb-000003
可选的，当第一指示信息指示至少两个目标值时，该方法还包括：接收第二指示信息，其中，第二指示信息用于指示至少两个目标值中的第一目标值。从第一目标值对应的预编码粒度中确定目标预编码粒度。上述对第一指示信息的解释，同样也适用于第二指示信息，本申请实施例在此不再赘述。可理解，终端设备还可以在步骤220之前，接收第二指示信息。例如，终端设备可以在接收第一指示信息之后，接收该第二指示信息。
可选的，第二指示信息可以指示第一目标值关联的预编码粒度集合的索引。示例性的，将预编码粒度集合记为第一集合和第二集合，第二指示信息可以为DCI中的一个字段，当该DCI中的字段指示0时，第一目标值关联第二集合的索引，当该DCI中的字段指示1时，第一目标值关联第一集合的索引。通过预编码粒度集合的索引，确定目标预编码粒度。可见，该中实施方式中，通过DCI中的字段指示预编码粒度集合的索引，不需要增加额外的指示信息，大大节省了信令开销。
步骤220，终端设备从至少一个目标值对应的预编码粒度中确定目标预编码粒度。对应地，网络设备也从至少一个目标值对应的预编码粒度中确定目标预编码粒度。
可选的，根据终端设备的能力信息，确定目标预编码粒度。其中，该能力信息为终端设备是否支持小于2RB的信息。
可选的，终端设备向网络设备上报能力信息，该能力信息指示终端设备支持小于2RB的能力信息。一种可能的实施方式，在接收第一指示信息之前，终端设备向网络设备上报能力信息；另一种可能的实施方式，在接收第一指示信息指示之后，终端设备向网络设备上报能力信息。本申请实施例对此不作限定。
可选的，终端设备或网络设备可以通过第一指示信息确定目标预编码粒度，也可以通过第一指示信息和第二指示信息联合指示确定目标预编码粒度。示例性的，当第一指示信息指示一个目标值时，可以通过第一指示信息确定目标预编码粒度；当第一指示信息指示至少两个目标值时，可以通过第一指示信息和第二指示信息联合指示确定目标预编码粒度。
一种可能的实施方式，从至少一个目标值对应的预编码粒度中确定目标预编码粒度，包括：至少一个目标值包括第一目标值，从第一目标值对应的预编码粒度中确定目标预编码粒度。此 时，通过第一指示信息的指示确定目标预编码粒度。
示例性的，第一集合A1为{n4，n1/wideband，n2-wideband，n4-wideband}，假设第一目标值对应n4，则根据第一目标值确定的目标预编码粒度为4RB；假设第一目标值对应n1/wideband，若终端设备支持1RB的预编码粒度，则根据第一目标值确定的目标预编码粒度为1RB，若终端设备不支持1RB的预编码粒度，则根据第一目标值确定的目标预编码粒度为wideband。
在另一种可能的实施方式中，从至少一个目标值对应的预编码粒度中确定目标预编码粒度，包括：至少一个目标值包括第一目标值和第二目标值。此时，通过第一指示信息和第二指示信息联合指示确定目标预编码粒度。
示例性的，第一集合A1为{n4，n1/wideband，n2-wideband，n4-wideband}，第二集合A2为{n4，wideband}，A1为第一指示信息为bundleSizeSet1时对应的目标值集合，且bundleSizeSet1指示A1中的一个目标值；A2为第一指示信息为bundleSizeSet2时对应的目标值集合，且bundleSizeSet2指示A2中的一个目标值。例如，根据bundleSizeSet1和bundleSizeSet2对应prb-Bundling Type配置参数可以定义为如下所示：
Figure PCTCN2020119700-appb-000004
可选的，根据第一指示信息的指示，从第一集合中确定第一目标值，从第二集合中确定第二目标值。根据第二指示信息的指示，从第一目标值和第二目标值中确定目标预编码粒度。此时，包括三种不同的方案，记为方案一至方案三。
以下以第二指示信息为DCI，且DCI中字段为PRB bundling size indicator为例，对方案一至方案三进行详细阐述。
方案一
在DCI中指示字段配置为0的情况下，目标预编码粒度从第二目标值对应的预编码粒度中确定。即n4为目标预编码粒度。也就是说，目标预编码粒度为4RB。
方案二
在DCI中指示字段配置为1，且第一目标值对应的预编码粒度为n4或，n1/wideband时，目标预编码粒度从第一目标值对应的预编码粒度中确定。
一种可能的实施方式中，第一目标值对应的预编码粒度为n4，则目标预编码粒度为4RB。
另一种可能的实施方式中，第一目标值对应的预编码粒度为n1/wideband，根据终端设备支持的能力信息，确定目标预编码粒度。若终端设备支持1RB的预编码粒度，则目标预编码粒度为1RB；若终端设备不支持1RB的预编码粒度，则目标预编码粒度为wideband。
方案三
在DCI中指示字段配置为1，且第一目标值对应的预编码粒度为n2-wideband或n4-wideband时，目标预编码粒度从第一目标值对应的预编码粒度中确定。当调度的物理资源块PRB是连续的且数量大于带宽区域(Bandwidth Part，BWP)包含的RB个数的一半时，目标预编码粒度为wideband；当调度的PRB是连续的且数量小于或等于BWP包含的RB个数的一半时，目标预编码粒度为n2或n4。
示例性的，第一目标值对应n2-wideband，BWP包含的RB个数为48RB，连续的带宽为30RB，则，BWP包含的RB个数的一半为24RB，连续的带宽大于带宽BWP包含的RB个数的一半，确定的目标预编码粒度为wideband。假设BWP包含的RB个数为48RB，连续的带宽为20RB，则BWP包含的RB个数的一半为24RB，连续的带宽小于BWP包含的RB个数的一半，确定的目标预编码粒度为2RB。A1为第一指示信息为bundleSizeSet1时对应的目标值集合，且bundleSizeSet1指示A1中的一个目标值；A2为第一指示信息为bundleSizeSet2时对应的目标值集合，且bundleSizeSet2指示A2中的一个目标值；
可见，通过上述bundleSizeSet1(Set1)和bundleSizeSet2(Set2)的联合指示，可以实现不同的PRB-BundlingType动态指示组合，如表2所示。
表2
编号 Set 1 Set 2
1 n1/WB 4
2 n1/WB WB
3 WB 4
4 WB WB
5 n2-WB 4
6 n2-WB WB
7 n4-WB 4
8 n4-WB WB
表2中，n1/WB为新增的支持n1的PRB-BundlingType动态指示组合。根据表2，当终端设备支持n1的预编码粒度时，指示n1，可以实现更精细的预编码粒度；当终端设备不支持n1的预编码粒度时，依旧指示WB。
可选的，至少一个目标值包括第一目标值和第二目标值；从至少一个目标值对应的预编码粒度中确定目标预编码粒度，包括：根据第二目标值对应的预编码粒度，从第一目标值对应的预编码粒度中确定目标预编码粒度。
可选的，第一目标值对应第一目标预编码粒度和第二目标预编码粒度，根据第二目标值对应的预编码粒度，从第一目标值对应的预编码粒度中确定目标预编码粒度，包括：
一种可能的实施方式，在第二目标预编码粒度与第二目标值对应的预编码粒度相同的情况下，则第一目标预编码粒度为目标预编码粒度。
另一种可能的实施方式，在第二目标预编码粒度与第二目标值对应的预编码粒度不同的情况下，则第二目标预编码粒度为目标预编码粒度。
示例性的，第一集合A1为{n1-n4，n1-wideband}，第二集合A2为{n4，n2，n2-wideband，n4-wideband}。A1为第一指示信息为bundleSizeSet1时对应的目标值集合，且bundleSizeSet1指示A1中的一个目标值；A2为第一指示信息为bundleSizeSet2时对应的目标值集合，且bundleSizeSet2指示A2中的一个目标值。例如根据bundleSizeSet1和bundleSizeSet2对应prb-Bundling Type配置参数可以定义为如下所示：
Figure PCTCN2020119700-appb-000005
将A1划分为不同的case，如表3所示，分别记为case1和case2。其中，case1对应第一目标预编码粒度，case2对应第二目标预编码粒度。
表3
不同case Set1取值1 Set1取值2
case1 n1 n1
case2 n4 wideband
此时，通过第一集合和第二集合的不同case确定的目标预编码粒度包括以下三种不同的情况，分别记为方案四至方案六。以下以第二指示信息为DCI为例，对方案四至方案六进行详细阐述。
方案四
在DCI中指示字段配置为0的情况下，目标预编码粒度从第一目标值对应的预编码粒度中确定。
若第二目标值对应的目标预编码粒度为一个，且与第二目标预编码粒度相同，则目标预编码粒度为第一目标预编码粒度。若第二目标值对应的预编码粒度与第二目标预编码粒度不同，则目标预编码粒度为第二目标预编码粒度。
示例性的,第二目标值对应的预编码粒度为n4，第二目标预编码粒度也为n4，第二目标值对应的预编码粒度与第二目标预编码粒度相同，则第一目标预编码粒度为目标预编码粒度，即n1。
若第二目标值对应的预编码粒度为n2-wideband，第二目标预编码粒度为n4，第二目标值对应的预编码粒度与第二目标预编码粒度均不相同，则第二目标预编码粒度为目标预编码粒度， 即n4。
若第二目标值对应的预编码粒度为n4-wideband，第二目标预编码粒度为n4，在调度的物理资源块PRB是连续的且数量大于带宽区域(Bandwidth Part，BWP)包含的RB个数的一半(二分之一)时，第二目标值为wideband，wideband与n4不同，则目标预编码粒度为n4；在调度的PRB是连续的且数量小于或等于带宽区域(Bandwidth Part，BWP)包含的RB个数的一半(二分之一)时，第二目标值为n4，与第二目标预编码粒度相同，则目标预编码粒度为n1。

方案五

一种可能的实施方式中，第二目标值对应的预编码粒度为n4，则目标预编码粒度为4RB。另一种可能的实施方式中，第一目标值对应n2，则目标预编码粒度为2RB。
另一种可能的实施方式中，若终端设备支持1RB的预编码粒度，则目标预编码粒度为1RB；若终端设备不支持1RB的预编码粒度，则目标预编码粒度为wideband。
方案六
在DCI中指示字段配置为1，且第二目标值对应的预编码粒度为n2-wideband或n4-wideband时，目标预编码粒度从第二目标值对应的预编码粒度中确定。当调度的物理资源块PRB是连续的且数量大于带宽区域(Bandwidth Part，BWP)包含的RB个数的一半(二分之一)时，目标预编码粒度为wideband；当调度的PRB是连续的且数量小于或等于BWP包含的RB个数的一半(二分之一)时，目标预编码粒度为n2或n4。
示例性的，第二目标值对应n2-wideband，BWP包含的RB个数为48RB，连续的带宽为30RB，则BWP包含的RB个数的一半(二分之一)为24RB，连续的带宽大于BWP包含的RB个数的一半，确定的目标预编码粒度为wideband。假设BWP包含的RB个数为48RB，连续的带宽为20RB，则BWP包含的RB个数的一半(二分之一)为24RB，连续的带宽小于BWP包含的RB个数的一半(二分之一)，确定的目标预编码粒度为2RB。
可见，如表4所示，在上述实施例中，第一集合A1为{n1-n4，n1-wideband}，第二集合A2为{n4，n2，n2-wideband，n4-wideband}，可以实现不同的PRB-BundlingType动态指示组合。
