技术领域
本申请涉及通信技术领域，具体而言，本申请涉及SPS PDSCH的确定方法、终端、电子设备及存储介质。
背景技术
半静态持续调度(Semi-Persistent Scheduling，SPS)是一种新的调度技术。简单地说，基站在某个时隙内为终端配置多个SPS PDSCH(半静态持续调度物理下行共享信道)以供终端使用。由于SPS具有“一次分配，多次使用”的特点，不需要基站在每个时隙都为终端下发下行控制信息(Downlink Control Information，DCI)，从而能够降低对应的物理下行控制信道(Physical Downlink Control Channel，PDCCH)开销。
终端在接收到基站配置的多个SPS PDSCH时，需要确定使用哪个或者哪些SPS PDSCH来进行数据的收发。目前，对于采用时分复用(Time Division Multiplexing，TDM)方式的5G网络，可以支持终端在一个时隙中接收2个或者多个SPS PDSCH；但是，对于采用频分复用(Frequency-division multiplexing，FDM)方式的5G网络，可能不支持终端在一个时隙中接收2个或者多个SPS PDSCH，进而可能影响空口资源，使得用户体验较差。
发明内容

第二方面，提供了一种终端，包括：激活资源确定模块，用于确定基站在一个时隙中激活的SPS PDSCH，其中，SPS PDSCH中包括用于承载单播业务的SPS PDSCH的第一SPS PDSCH集合和/或用于承载广播/组播业务的SPS PDSCH的第二SPS PDSCH集合；接收资源确定模块，用于根据激活的SPS PDSCH承载的业务的类型，以及终端所支持的接收PDSCH的能力，确定用于收发数据的SPS PDSCH；其中，终端所支持的接收PDSCH的能力包括所述终端确定支持的频分多路复用FDM复用方式的能力。
第三方面，提供一种静态持续调度物理下行共享信道SPS PDSCH确定装置，包括存储器，收发机，处理器。存储器用于存储计算机程序。收发机用于在处理器的控制下收发数据。处理器用于读取存储器中的计算机程序并执行如第一方面SPS PDSCH的确定方法的步骤。

具体实施方式
下面详细描述本申请的实施例，实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能解释为对本申请的限制。
本技术领域技术人员可以理解，除非特意声明，这里使用的单数形式“一”、“一个”和“该”也可以包括复数形式。应该进一步理解的是，本申请的说明书中使用的措辞“包括”是指存在特征、整数、步骤、操作、元件和/或组件，但是并不排除存在或添加一个或多个其他特征、整数、步骤、操作、元件、组件和/或它们的组。应该理解，当我们称元件被“连接”或“耦接”到另一元件时，它可以直接连接或耦接到其他元件，或者也可以存在中间元件。此外，这里使用的“连接”或“耦接”可以包括无线连接或无线耦接。这里使用的措辞“和/或”包括一个或更多个相关联的列出项的全部或任一单元和全部组合。
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
首先对本申请涉及的几个名词进行介绍和解释：
1)单播(Unicast)业务，是指数据报文的接收和发送只在两个网络节点之间进行。
2)组播(Multicast)业务，顾名思义，同组成员才能收到数据报文，也就是说，当数据报文的发送节点发送一个数据目的地址是这个组的组播地址的时候，所有在这个组的节点都会收到这个发送的内容。本申请实施例中的组播可以是组播业务，也可以是广播业务，或者系统广播消息。
3)广播/组播业务(也被称作BCAST业务)，提供空波广播(sky wave broadcast)或辅助信息给移动终端。该广播/组播业务包括广播业务和组播业务。由服务提供商提供的广播业务发送可用信息给已经预订了服务提供商的业务的每个用户。另外，由服务提供商提供的组播业务只发送信息给预订了特定主题或内容的确定的用户组。
对于5G R17的广播/组播业务，标准讨论了支持单播PDSCH和广播/组播PDSCH的FDM方式。由于基站可以给广播/组播和单播配置多个SPS PDSCH，由于各个SPS PDSCH的配置周期可能不同，这就有可能在某些时隙中“聚集N个“SPS PDSCH，这些SPS PDSCH超过了用户设备(User Equipment，UE)的接收能力。比如：在一个时隙中，可能出现FDM的PDSCH个数超过UE的接收能力或者PDSCH总数超过UE的接收能力的情况。这就需要终端和基站使用相同的方法，确定终端需要接收哪些PDSCH。
现有5G R16中，标准针对单播的TDM的复用场景，给出一个时隙中有多个SPS PDSCH(没有PDCCH调度的PDSCH)，UE确定接收哪些PDSCH的方法，该方法可以包括如下Step 0至Step 3。
需要说明的是，在该方法中，假设：集合Q是在一个时隙中激活的SPS PDSCH的集合；在集合Q中，每个SPS PDSCH都被配置有彼此不同的配置索引sps-ConfigIndex；在该方法中，按照SPS PDSCH配置索引sps-ConfigIndex的数值从小到大的顺序，开始对集合Q中的SPS PDSCH进行遍历，其中，开始遍历之前，可以设置遍历参数j(即，UE已经选择并进行解调的PDSCH的个数，该遍历参数也可以被称为迭代次数)为0；UE在一个时隙中支持的接收PDSCH的最大个数为M。
-Step 0：设置j＝0，j是UE已经选择并进行解调SPS PDSCH的个数。
-Step 1：UE选择集合Q中SPS PDSCH配置索引sps-ConfigIndex的数值最小的一个SPS PDSCH，设置j＝j+1，并且将选择的SPS PDSCH记为存活PDSCH。存活PDSCH是指UE确定的要通过其进行收发数据的PDSCH。
-Step 2：从集合Q中删除在Step 1中确定的存活PDSCH以及和确定的存活PDSCH有交叠(例如，时域交叠或频域交叠)的所有PDSCH(标注：不支持FDM)。
-Step 3：重复执行Step 1和Step 2，直到集合Q为空，或者直到j等于M。
现有技术方案仅仅支持TDM复用的多SPS PDSCH场景，不支持FDM复用的多SPS PDSCH情况。
本申请提供的SPS PDSCH确定方法、装置、电子设备和计算机可读存储介质，至少解决现有技术的如上技术问题。
本申请实施例的核心构思可以在于：
-以现有SPS PDSCH配置索引sps-ConfigIndex的数值作为判断接收优先级的依据(或者以组播高优先级，然后以SPS PDSCH配置索引sps-ConfigIndex的数值进行优先级判断)；
-在确定存活PDSCH时，增加支持FDM复用方式的判断条件和FDM复用个数判断。
需要说明的是，对于支持FDM的复用方式，以及一个时隙中支持PDSCH的个数，依赖于终端能力以及基站配置情况，为了便于进行技术方案实施，以不同的UE能力进行区别，分别对应不同实施例。
需要说明的是，为了使UE更好地判断存活SPS PDSCH，在技术方案上，还可以补充如下内容1和2。
1.在一个时隙中被激活的多个SPS PDSCH当中，相对于单播SPS PDSCH，组播SPS PDSCH高优先级被确定为存活PDSCH。
实现方法可以包括如下两个方法，即，方法A和方法B。
方法A：使所有的单播SPS PDSCH的配置索引sps-ConfigIndex增加一个偏移量，然后按照所设置的优先级顺序从高到低进行存活PDSCH的判断。
例如，若终端设置配置索引的数值越小对应的优先级越高，则根据偏移量，终端可以调整用于承载单播业务的第一SPS PDSCH集合中各SPS PDSCH的SPS PDSCH 配置索引的数值，使得调整后的第一SPS PDSCH集合中各SPS PDSCH的SPS PDSCH配置索引的数值大于用于承载广播/组播业务的第二SPS PDSCH集合中SPS PDSCH配置索引对应的最大数值。
相应的调整SPS PDSCH配置索引的方法可以用以下计算公式表示：
SPS PDSCH_ID’＝SPS PDSCH_ID+offset
SPS PDSCH_ID’表示调整后的SPS PDSCH配置索引的数值大小；SPS PDSCH_ID表示调整前的SPS PDSCH配置索引的数值大小；offset表示偏移量，为正整数，例如可以是终端所支持的接收SPS PDSCH的最大个数。
举例来说，若激活的SPS PDSCH包括u-1、u-2、m-3、m-4、u-5，共5个SPS PDSCH，其中u表示第一SPS PDSCH集合中的SPS PDSCH，m表示第二SPS PDSCH集合中的SPS PDSCH，u或m后面的阿拉伯数值表示原始的SPS PDSCH配置索引，若终端所支持的接收SPS PDSCH的最大个数为2，并且终端以配置索引的数值越小对应的优先级越高为原则来确定用于收发数据的SPS PDSCH，那么，可以将偏移量设置为4，使得u-1调整后的SPS PDSCH配置索引为u-5，大于m-4的配置索引，优先从第二SPS PDSCH集合中的SPS PDSCH确定出用于收发的SPS PDSCH(即，m-3)。应当理解的是，当u-1被调整配置索引时，u-2和u-5也会基于偏移量分别被调整为u-6和u-9。
又例如，若终端设置配置索引的数值越大对应的优先级越高，则根据偏移量，终端可以调整用于承载单播业务的第一SPS PDSCH集合中各SPS PDSCH的SPS PDSCH配置索引的数值，使得调整后的第一SPS PDSCH集合中各SPS PDSCH的SPS PDSCH配置索引的数值小于用于承载广播/组播业务的第二SPS PDSCH集合中SPS PDSCH配置索引对应的最小数值。
相应的调整SPS PDSCH配置索引的方法可以用以下计算公式表示：
SPS PDSCH_ID’＝SPS PDSCH_ID-offset
SPS PDSCH_ID’表示调整后的SPS PDSCH配置索引的数值大小；SPS PDSCH_ID表示调整前的SPS PDSCH配置索引的数值大小；offset表示偏移量，为正整数，例如可以是终端所支持的接收SPS PDSCH的最大个数。
举例来说，若激活的SPS PDSCH包括u-1、u-2、m-3、m-4、u-5，共5个SPS PDSCH，其中u表示为第一SPS PDSCH集合中的SPS PDSCH，m表示第二SPS PDSCH集合中的SPS PDSCH，u或m后面的阿拉伯数值表示原始的SPS PDSCH配置索引，若终端所支持的接收SPS PDSCH的最大个数为2，并且终端以配置索引的数值越大对应的优先级越高为原则来确定用于收发数据的SPS PDSCH，那么可以将偏移量设置为3，使得u-5调整后的SPS PDSCH配置索引为u-2，小于m-3的配置索引，优先从第二SPS PDSCH集合中的SPS PDSCH确定出用于收发的SPS PDSCH(即，m-4)。应当理解的是，当u-5被调整配置索引时，u-1和u-2也会基于偏移量分别被调整为u-(-2) 和u-(-1)。
方法B：优先对组播SPS PDSCH进行存活SPS PDSCH的判断，再对单播SPS PDSCH进行存活SPS PDSCH的判断。
2.基站还配置和激活虚拟组播SPS PDSCH配置给终端，虚拟组播SPS PDSCH只参与存活PDSCH的判断，但不被UE接收，进而不被统计在接收PDSCH个数中。
下面以具体实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本申请的实施例进行描述。
图1示例性地示出了本申请实施例的系统的示意性架构图。参见图1，系统可以包括基站和用户设备。图1中仅示例性的示出了一个基站和一个用户设备，但不限于此。例如，在本申请实施例中，系统可以包括两个或更多个用户设备。
本申请实施例提供的基站可以为通用移动通信系统(Universal Mobile Telecommunications System，UMTS)下的基站(Node B，NB)、长期演进技术(Long Term Evolution，LTE)下的演进型基站(eNodeB，eNB)或者第五代移动通信系统下的基站或控制器。
本申请实施例涉及的用户设备(也称终端设备)，可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的系统中，终端设备的名称可能也不相同，例如在5G系统中，终端设备可以称为用户设备(User Equipment，UE)。无线终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网(Core Network，CN)进行通信，无线终端设备可以是移动终端设备，如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol，SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device)，本申请实施例中并不限定。
此外，本申请实施例提供的技术方案可以适用于多种系统，尤其是5G系统。例如适用的系统可以是全球移动通讯(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)通用分组无线业务(general packet radio  service，GPRS)系统、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)系统、高级长期演进(long term evolution advanced，LTE-A)系统、通用移动系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)系统、5G新空口(New Radio，NR)系统等。这多种系统中均包括终端设备和网络设备。系统中还可以包括核心网部分，例如演进的分组系统(Evolved Packet System，EPS)、5G系统(5GS)等。
图2示例性地示出了本申请实施例的SPS PDSCH的确定方法的流程示意图。在本申请实施例中，SPS PDSCH的确定方法可以由终端执行，例如，可以由图1的用户设备执行。如图2所示，SPS PDSCH的方法可以包括步骤S101和步骤S102。
在步骤S101中，可以确定基站在一个时隙中激活的SPS PDSCH，其中，SPS PDSCH中包括用于承载单播业务的SPS PDSCH的第一SPS PDSCH集合和/或用于承载广播/组播业务的SPS PDSCH的第二SPS PDSCH集合。
在本申请实施例中，第一SPS PDSCH集合可以包括至少一个用于承载单播业务的单播SPS PDSCH，第二SPS PDSCH集合可以包括至少一个用于承载广播/组播业务的组播SPS PDSCH。
需要说明的是，本申请实施例中的一个时隙可以指包含14个符号的时间单元，或者包含12个符号的时间单元。一个时隙也可以表示其它特定的时间单元，比如，包含整数倍个14个符号或者整数倍个12个符号的时间单元，在此不做限定。
在本申请实施例中，可以根据激活的SPS PDSCH的加扰DCI来区分单播SPS PDSCH和组播SPS PDSCH。例如，使用CS-RNTI做DCI加扰的为单播SPS PDSCH，以GCS-RNTI做DCI加扰的为组播SPS PDSCH。
在本申请实施例中，组播可以用多播、多播组播、广播组播、广播/组播等来替代。
区别于现有技术中基站激活的SPS PDSCH均是承载同一类业务(例如，单播或组播)的SPS PDSCH，在本申请实施例中，激活的SPS PDSCH既包括单播SPS PDSCH，也包括组播SPS PDSCH，其中单播SPS PDSCH均归类于第一SPS PDSCH集合中，组播SPS PDSCH均归类于第二SPS PDSCH集合中，为UE获取多个类型的SPS PDSCH奠定了基础。应当理解的是，激活的SPS PDSCH即基站向UE发送的SPS PDSCH，UE需要进一步从激活的SPS PDSCH中筛选出用于收发数据的SPS PDSCH，也即存活SPS PDSCH。
在步骤S102中，根据激活的SPS PDSCH承载的业务的类型，以及终端所支持的接收PDSCH的能力，确定用于收发数据的SPS PDSCH。
在本申请实施例中，终端所支持的接收PDSCH的能力包括终端确定支持的频分多路复用FDM复用方式的能力以及一个时隙中支持接收的PDSCH的个数。
在本申请实施例中，终端确定支持的FDM复用方式的能力是指当存在具有FDM复用关系的一组SPS PDSCH时，该组SPS PDSCH中允许被终端复用的单播SPS PDSCH和组播SPS PDSCH的数量。基于该能力，终端最终确定的用于收发数据的SPS PDSCH如果存在时域交叠，那么需要满足终端确定支持的FMD复用方式的能力。例如，如果终端确定支持的FDM复用方式的能力为允许复用一个单播SPS PDSCH和2个组播SPS PDSCH，那么在最终确定的用于收发数据的SPS PDSCH中，如果存在一个单播SPS PDSCH并且该单播SPS PDSCH还与其他SPS PDSCH具有FDM复用关系，那么该其他SPS PDSCH必须为组播SPS PDSCH，并且数量不能超过2个。
本申请实施例的SPS PDSCH的确定方法，通过确定基站在一个时隙中激活的SPS PDSCH，其中，SPS PDSCH中包括用于承载单播业务的第一SPS PDSCH集合和/或用于承载广播/组播业务的第二SPS PDSCH集合；支持实现确定用于收发数据的多类型的SPS PDSCH，根据激活的SPS PDSCH承载的业务的类型，以及终端所支持的接收PDSCH的能力(例如，终端确定支持的频分多路复用FDM复用方式的能力)，确定用于收发数据的SPS PDSCH，给出了PDSCH支持FDM复用方式时，确定存活PDSCH的方法，可以确保终端能够正确有效地接收SPS PDSCH，从而节约空口资源，提升用户体验。
在上述各实施例的基础上，作为一种可选实施例，终端确定支持的FDM复用方式的能力可以为：在存在FDM复用关系的SPS PDSCH中，支持确定用于收发数据的SPS PDSCH所承载的业务的类型以及对应各类型的SPS PDSCH的数量。
表1示例性地示出了本申请实施例的FDM复用能力表。如表1所示，在本申请实施例中，终端确定支持的FDM复用方式的能力可以包括两种，即可以具有两种FDM复用能力，表中分别表示为能力A和能力B。
能力A是指在一个时隙中，仅仅支持单播PDSCH和组播PDSCH的FDM复用方式，能力B是指在一个时隙中，支持单播PDSCH和组播PDSCH或者支持组播PDSCH和组播PDSCH的FDM复用方式。当然，UE终端可以上报(例如，向基站上报)支持能力A或者能力B，也可以上报即不支持能力A也不支持能力B。这里不做限定。
Figure PCTCN2022122328-appb-000001
表1 FDM复用能力表
需要说明是，表1中，N表示在一个时隙中对于存在频域交叠和/或时域交叠的一 组SPS PDSCH中终端所支持的最大复用数量；在M＝{2,4,5,7,8,10}当中，数字2、4、5、7、8、10分别表示激活的SPS PDSCH所对应的配置索引。能力A和能力B，以及参数N和M的数值大小，可以根据终端上报给基站，或者通过基站和终端进行协商确定。后续实施例描述中，均假设N＝2，M＝M为例子进行说明。
在上述各实施例的基础上，作为一种可选实施例，FDM复用方式的能力(能力A)具体为：对于存在FDM复用关系的SPS PDSCH，支持将1个承载单播业务的SPS PDSCH和最多n-1个承载广播/组播业务的SPS PDSCH确定为用于收发数据的SPS PDSCH。n为在一个时隙中对于存在FDM复用关系的一组SPS PDSCH中，终端用于收发数据的SPS PDSCH的最大复用数量。
也就是说，在本申请实施例中，FDM复用能力可以指支持存在FDM关系的1个单播SPS PDSCH与一个或多个组播SPS PDSCH进行FDM复用。也即，本申请实施例不支持存在资源单元(Resource Element，RE)交叠的SPS PDSCH同时作为存活SPS PDSCH，也不支持一个单播SPS PDSCH与超过n-1个数的组播SPS PDSCH同时作为存活SPS PDSCH。
图3为本申请实施例的支持FDM复用能力A的场景的示意图。如图3所示，本申请实施例适用于激活多个单播SPS PDSCH和一个组播SPS PDSCH的场景、激活多个单播SPS PDSCH和多个组播SPS PDSCH的场景、激活一个单播SPS PDSCH和多个组播SPS PDSCH的场景。图3中的u-1表示针对单播(unicast)的SPS PDSCH配置，其配置索引(也被称为配置ID)sps-ConfigIndex数值为1；m-3表示针对组播(multicast)的SPS PDSCH配置，其配置ID(sps-ConfigIndex)数值为3。
在上述各实施例的基础上，作为一种可选实施例，根据激活的SPS PDSCH承载的业务的类型，以及终端所支持的接收PDSCH的能力，确定用于收发数据的SPS PDSCH，可以包括步骤S201和步骤S202。
在步骤S201中，确定激活的SPS PDSCH的优先级。
在现有技术方案中，确定SPS PDSCH(没有PDCCH调度的PDSCH)的优先级，是根据SPS PDSCH配置索引(sps-ConfigIndex)来确定的。在本申请实施例中，为了充分利用现有过程，减少对协议的修改，可以依然以SPS PDSCH配置索引的数值大小来确定优先级，同时也不排除其他的确定优先级的方法，比如：组播SPS PDSCH的优先级高于单播SPS PDSCH的优先级，或者能够形成FDM的SPS PDSCH的优先级高于能够形成TDM的PDSCH的优先级。
应当理解的是，在以SPS PDSCH配置索引的数值大小来确定优先级时，既可以是配置索引的数值越小，对应的优先级越高，也可以是配置索引的数值越大，对应的优先级越高。
在本申请实施例中，组播PDSCH的优先级高于单播PDSCH的优先级，可以指先从组播SPS PDSCH集合(也即第二SPS PDSCH集合)中确定用于收发数据的SPS  PDSCH，若从第二SPS PDSCH集合中确定的用于收发数据的SPS PDSCH的数量不满足终端支持的接收PDSCH的能力，则继续从第一SPS PDSCH集合中确定用于收发数据的SPS PDSCH，直至满足终端所支持的接收SPS PDSCH的能力。
在步骤S202中，根据激活的SPS PDSCH的优先级从高到低的顺序，结合激活的SPS PDSCH承载的业务的类型以及终端所支持的接收PDSCH的能力，确定用于收发数据的SPS PDSCH。
可以理解的是，在本申请实施例中，可以根据优先级从高到低的顺序，对激活的SPS PDSCH进行遍历；当将当前遍历到的SPS PDSCH确定为用于收发数据的SPS PDSCH时，根据当前遍历到的SPS PDSCH承载的业务的类型(也即该SPS PDSCH是单播SPS PDSCH还是组播SPS PDSCH)，从激活的SPS PDSCH中删除不满足终端所支持的接收PDSCH的能力的SPS PDSCH，从而避免在后续遍历到影响之前已经确定的用于收发数据的SPS PDSCH。
在上述各实施例的基础上，作为一种可选实施例，根据激活的SPS PDSCH的优先级从高到低的顺序，结合激活的SPS PDSCH承载的业务的类型以及终端所支持的接收PDSCH的能力，确定用于收发数据的SPS PDSCH，可以包括：根据激活的SPS PDSCH的优先级从高到低的顺序，结合激活的SPS PDSCH承载的业务的类型以及终端所支持的FDM复用方式的能力，从激活的SPS PDSCH中确定用于收发数据的SPS PDSCH，直至确定用户收发数据的SPS PDSCH满足终端所支持的接收SPS PDSCH的最大个数。
具体的，在本申请实施例中，假设：在一个时隙中激活的SPS PDSCH集合可以表示为集合Q；在集合Q中，组播SPS PDSCH和单播SPS PDSCH的SPS PDSCH配置索引的数值可以彼此不同；优先级根据SPS PDSCH配置索引(sps-ConfigIndex)的数值大小来确定，数值小的优先级高。
UE确定用于收发数据的PDSCH的方法可以包括：按照SPS PDSCH配置索引(sps-ConfigIndex)的数值从小到大的顺序，开始对集合Q中的SPS PDSCH进行遍历，其中，开始遍历之前，可以设置遍历参数j(即，UE已经选择并进行解调的PDSCH的个数，该遍历参数也可以被称为迭代次数)为0；当当前遍历的SPS PDSCH被UE选择并且被确定为用于收发数据的SPS PDSCH(即，存活PDSCH)时，设置遍历参数j＝j+1，并且从集合Q中删除不满足终端所支持的FDM复用方式的能力的SPS PDSCH，从而避免在后续遍历到影响之前已经确定的用于收发数据的SPS PDSCH。
例如，该方法可以通过如下Step 10至Step 13实现。
-Step 10：设置j＝0，j是UE选择并进行解调PDSCH的个数。
-Step 11：UE选择集合Q中配置索引sps-ConfigIndex的数值最小的一个PDSCH，设置j＝j+1，并且将选择的PDSCH记为存活PDSCH。
-Step 12：如果UE支持复用能力A(即，unicast+multicast的FDM复用)，则 执行如下Step 2_1至Step 2_3。
Step 12_1：标记在Step 11中确定的存活PDSCH的类型(如：单播类型，或者组播类型)。
Step 12_2：从集合Q中删除和在Step 11中确定的存活PDSCH相同类型且有时域交叠的所有PDSCH(相同类型的PDSCH之间，不支持FDM)。
Step 12_3：从集合Q中删除在Step 11中确定的存活PDSCH以及和确定的存活PDSCH有RE资源交叠的所有PDSCH(PDSCH之间，时域资源和频域资源不能相互冲突，无论是相同类型还是不同类型)。
-Step 13：重复执行Step 11和Step 12，直到集合Q为空，或者直到j等于M(M为UE在一个时隙中支持接收最大PDSCH的个数)。
上述存活PDSCH可以作为终端需要接收的PDSCH，即终端确定的用于收发数据的SPS PDSCH。
需要说明的是：
1、在本申请实施例中，SPS PDSCH可以是激活且不和半静态TDD配置冲突的SPS PDSCH。
2、对于SPS PDSCH的集合Q，考虑到SPS PDSCH需要在下行符号上传输，需要先删除和上行符号有时域交叠的SPS PDSCH。
3、在Step 11中每选出一个存活PDSCH，就需要从相应的集合Q中移除。
下面结合一个具体的例子进行说明。图4示例性地示出了本申请另一个实施例中的一个时隙中激活的SPS PDSCH在时域和频域上的关系示意图。需要说明的是，该图4中横向表示时域，纵向表示频域，若两个SPS PDSCH在纵向上存在交叠，表示两个SPS PDSCH存在资源单元(Resource Element，RE)交叠，若两个SPS PDSCH在横向上存在交叠但在纵向上不存在交叠，表示两个SPS PDSCH存在FDM关系。
图4所示的时隙一共激活了10个SPS PDSCH，其中第一SPS PDSCH集合包括u-1、u-2、u-5、u-6和u-8，第二SPS PDSCH集合包括m-3、m-4、m-7、m-9和m-10，u和m后面的阿拉伯数字表示相应SPS PDSCH对应的配置索引，其中，u-1与m-4和u-8存在FDM关系(即，u-1、m-4和u-8为存在FDM复用关系的一组SPS PDSCH)，u-1与m-10存在RE交叠，u-2与m-4、u-6以及m-7存在FDM关系(即，u-2、m-4、u-6以及m-7为存在FDM复用关系的一组SPS PDSCH)，u-5和m-9存在FDM关系(即，u-5和m-9为存在FDM复用关系的一组SPS PDSCH)，等等。
假设UE上报的接收能力N＝2，M＝5。也就是说，假设：在存在FDM复用关系的一组SPS PDSCH中，终端用于收发数据的SPS PDSCH的最大复用数量为2，且在一个时隙中，终端支持接收的PDSCH的最大个数为5。例如，在存在FDM复用关系的一组SPS PDSCH中，例如在u-2、m-4、u-6以及m-7中，支持将1个承载单播业务的SPS PDSCH(例如，u-2)和最多n-1＝1个承载广播/组播业务的SPS PDSCH(例 如，m-4)确定为用于收发数据的SPS PDSCH。
第一次遍历循环(loop-1)时：选择配置索引sps-ConfigIndex最小的PDSCH(即，u-1)作为第1个存活PDSCH，删除和该存活PDSCH具有相同数据类型且有时域交叠的u-8，删除和该存活PDSCH有RE交叠(频域交叠)的m-10。
第二次遍历循环(loop-2)时：选择配置索引sps-ConfigIndex最小的PDSCH(即，u-2)作为第2个存活PDSCH，删除和该存活PDSH具有相同数据类型且有时域交叠的u-6。
第三次遍历循环(loop-3)时：选择配置索引sps-ConfigIndex最小的PDSCH(即，m-3)作为第3个存活PDSCH，删除和该存活PDSCH具有相同数据类型且有FDM关系的m-9。
第四次遍历循环(loop-4)时：选择配置索引sps-ConfigIndex最小的PDSCH(即，m-4)作为第4个存活PDSCH，删除和该存活PDSCH具有相同数据类型且有FDM关系的m-7。
第五次遍历循环(loop-5)时：选择配置索引sps-ConfigIndex最小的PDSCH(即，u-5)作为第5个存活PDSCH。
在上述各实施例的基础上，在本申请实施例中，还可以分别按照单播和组播维度各进行M个存活PDSCH的确定，然后按照单播和多播存活的PDSCH，以配置索引sps-ConfigIndex的数值从小到大，依次取M个PDSCH作为存活及接收的PDSCH。具体的，根据激活的SPS PDSCH承载的业务的类型，以及终端所支持的接收PDSCH的能力，确定用于收发数据的SPS PDSCH可以包括步骤S301～S304。
在步骤S301中，分别确定第一SPS PDSCH集合中各SPS PDSCH的优先级以及第二SPS PDSCH集合中各SPS PDSCH的优先级。
由上述实施例可知，本申请实施例可以根据各SPS PDSCH的配置索引的数值作为确定优先级的依据。
在步骤S302中，根据第一SPS PDSCH集合中各SPS PDSCH的优先级，结合终端所支持的接收PDSCH的能力，从第一SPS PDSCH集合中确定用于收发数据的第一候选SPS PDSCH。
在步骤S303中，根据第二SPS PDSCH集合中各SPS PDSCH的优先级，结合终端所支持的接收PDSCH的能力，从第二SPS PDSCH集合中确定用于收发数据的第二候选SPS PDSCH。
在步骤S304中，从用于收发数据的第一候选SPS PDSCH和第二候选SPS PDSCH中确定用于收发数据的SPS PDSCH。
在上述各实施例的基础上，作为一种可选实施例，从用于收发数据的第一候选SPS PDSCH和第二候选SPS PDSCH中确定用于收发数据的SPS PDSCH可以包括：确定第一候选SPS PDSCH和第二候选SPS PDSCH的各SPS PDSCH的优先级；根据 第一候选SPS PDSCH和第二候选SPS PDSCH的各SPS PDSCH的优先级从高到低的顺序，确定不超过最大个数的用于收发数据的SPS PDSCH。
在本申请实施例中，可以根据第一候选SPS PDSCH和第二候选SPS PDSCH的各SPS PDSCH的配置索引的数值作为判断优先级的依据，从而可以对第一候选SPS PDSCH和第二SPS PDSCH中的各SPS PDSCH，按照优先级从高到低的顺序，再次判断两个候选SPS PDSCH中是否存在不满足终端所支持的接收PDSCH的能力的SPS PDSCH，从而获得最终的用户收发数据的SPS PDSCH。
上述步骤S301～S303具体可以通过如下包括Step 20至Step 23的STEP A循环来实现。
STEP A循环中的Step 20至Step 23与上述Step 10至Step 13类似，且涉及到的参数也与Step 10至Step 13中涉及到的参数类似，在此不再重复描述。
-Step 20：设置j＝0，j是UE选择并进行解调PDSCH的个数。集合R是在一个时隙中激活的同一类型的SPS PDSCH集合(例如，集合R可以表示第一SPS PDSCH集合或者第二SPS PDSCH集合)。
-Step 21：UE选择集合R中配置索引sps-ConfigIndex的数值最小的一个PDSCH，设置j＝j+1，并且将选择的PDSCH记为存活PDSCH。
-Step 22：从集合R中删除在Step 21中确定的存活PDSCH以及和确定的存活PDSCH有时域交叠或频域交叠的所有PDSCH(不支持FDM)。
-Step 23：重复执行Step 21和Step 22，直到集合R为空，或者直到j等于M(M为UE在一个时隙中支持接收最大PDSCH的个数)。
如果UE支持复用能力A(unicast+multicast的FDM复用)，则上述步骤S304可以通过如下包括Step 30至Step 33的STEP B循环来实现。
-Step 30：设置j＝0，j是UE选择并进行解调PDSCH的个数。集合P是在STEP A循环中确定的存活PDSCH集合(包括单播和多播的存活PDSCH)。
-Step 31：UE选择集合P中配置索引sps-ConfigIndex数值最小的一个PDSCH，设置j＝j+1，并且将选择的PDSCH记为存活PDSCH。
-Step 32：从集合P中删除在Step 31中确定的存活PDSCH以及和确定的存活PDSCH有RE交叠的所有PDSCH(Unicast和multicast的PDSCH时域资源或频域资源不能冲突)。
-Step 33：重复执行Step 31和Step 32，直到集合P为空，或者直到j等于M(M为UE在一个时隙中支持接收最大PDSCH的个数)。
需要说明的是：
1、对于SPS PDSCH的集合Q，考虑到SPS PDSCH需要在下行符号上传输，需要先删除和上行符号有时域交叠的SPS PDSCH。
2、对于Step 21和Step 31中选出的存活PDSCH，需要从相应的集合R和P中移 除。
下面，以图4所示的实施例为例，进行详细描述。
对于第一SPS PDSCH集合的STEP A循环：存活的PDSCH有u-1、u-2、u-5。
对于第二SPS PDSCH集合的STEP A循环：存活的PDSCH有m-3、m-4、m-10。
对于STEP B循环，最终确定的存活的PDSCH有u-1、u-2、m-3、m-4、u-5(因为m-10与u-1存在RE交叠，所以被排除)。
在上述各实施例的基础上，作为一种可选实施例，确定的用于收发数据的SPS PDSCH之间不存在频域交叠。
若确定的用于接收数据的SPS PDSCH中存在至少一个时域交叠的SPS PDSCH组，则时域交叠的SPS PDSCH组中包括的1个承载单播业务的SPS PDSCH和最多n-1个承载广播/组播业务的SPS PDSCH被确定为用于收发数据的SPS PDSCH。
在上述各实施例的基础上，作为一种可选实施例，支持的FDM复用方式的能力(能力B)具体可以为：对于存在FDM复用关系的SPS PDSCH，支持将1个承载单播业务的SPS PDSCH和最多n-1个承载广播/组播业务的SPS PDSCH确定为用于收发数据的SPS PDSCH，或支持将最多n个承载广播/组播业务的SPS PDSCH确定为用于收发数据的SPS PDSCH。n为对于在一个时隙中存在频域交叠和/或时域交叠的一组SPS PDSCH中终端支持的最大复用数量。
图5为本申请实施例的支持FDM复用能力B的场景的示意图。如图5所示，本申请实施例适用于激活多个单播SPS PDSCH和一个组播SPS PDSCH的场景、激活多个单播SPS PDSCH和多个组播SPS PDSCH的场景、只激活多个组播SPS PDSCH的场景。图5中的u-1表示针对单播(unicast)的SPS PDSCH配置，配置ID(sps-ConfigIndex)数值为1。m-3表示针对组播(multicast)的SPS PDSCH配置，配置ID(sps-ConfigIndex)数值为3。
在上述各实施例的基础上，作为一种可选实施例，根据激活的SPS PDSCH承载的业务的类型，以及终端所支持的接收PDSCH的能力，确定用于收发数据的SPS PDSCH，可以包括：确定激活的SPS PDSCH的优先级；根据激活的SPS PDSCH的优先级从高到低的顺序，结合激活的SPS PDSCH的承载的业务的类型以及终端所支持的接收PDSCH的能力，确定用于收发数据的SPS PDSCH。
在能力B的复用场景下，确定存活PDSCH方案要点可以如下：
1、配置ID(sps-ConfigIndex)以数值为优先级进行判断(例如，数值小的优先级高，或者反之)。
2、不同业务类型PDSCH的FDM复用的判断：当两个PDSCH的业务类型不同(如：一个为单播，另外一个为组播)，时域上有交叠，但资源单元(RE，resource element)上没有交叠时，将该两个PDSCH称为不同业务类型PDSCH的FDM复用。
3、组播业务PDSCH的FDM复用的判断：当两个PDSCH的业务类型都是组播 类型，时域上有交叠，但RE上没有交叠时，将该两个PDSCH称为组播业务PDSCH的FDM复用。
4、限制FDM的PDSCH的个数，不超过相应的UE能力。
在上述各实施例的基础上，作为一种可选实施例，根据激活的SPS PDSCH的优先级从高到低的顺序，结合激活的SPS PDSCH的承载的业务的类型以及终端所支持的接收PDSCH的能力，确定用于收发数据的SPS PDSCH，可以包括：若根据顺序确定的当前遍历的SPS PDSCH为单播SPS PDSCH，则在激活的SPS PDSCH集合中删除与当前遍历的SPS PDSCH时域交叠的SPS PDSCH；若根据顺序确定的当前遍历的SPS PDSCH为组播SPS PDSCH，且当前遍历的SPS PDSCH与已确定的用于收发数据的SPS PDSCH中与当前遍历的SPS PDSCH存在FDM关系的SPS PDSCH之和超过UE能力的最大个数，则不将当前遍历的SPS PDSCH确定为用于收发数据的SPS PDSCH，在激活的SPS PDSCH集合中删除当前遍历的SPS PDSCH。
在一个时隙中，FDM复用最多2个(N＝2)PDSCH,但接收PDSCH总数为M个(M>2)。
假设：组播SPS PDSCH和单播SPS PDSCH的配置索引sps-ConfigIndex的数值彼此不同，优先级根据SPS PDSCH配置ID(sps-ConfigIndex)的数值来确定，数值小的优先级高。UE确定接收PDSCH的方法过程可以包括如下Step 40至Step 43。
-Step 40：设置j＝0，j是UE选择并进行解调PDSCH的个数。集合Q是在一个时隙中激活的且不和半静态TDD配置冲突的SPS PDSCH集合。
-Step 41：UE选择集合Q中配置索引sps-ConfigIndex的数值最小的一个PDSCH，设置j＝j+1，并且将选择的PDSCH记为存活PDSCH。
-Step 42：如果UE支持复用能力B(unicast/multicast+multicast的FDM复用)，则执行如下Step 42_1至42_4。
Step 42_1：标记在Step 41中确定的存活PDSCH的类型(如：单播类型，或者组播类型)。
Step 42_2：如果Step 42_1中标记的类型是单播，则从集合Q中删除和在Step 41中确定的存活PDSCH的有相同类型且有FDM关系的所有PDSCH(单播类型的PDSCH，不支持FDM)。
Step 42_3：从集合Q中删除在Step 41中确定的存活PDSCH以及和确定的存活PDSCH的有RE资源交叠的所有PDSCH(标注：两个PDSCH之间时域资源和频域资源不能相互冲突，但组播PDSCH之间支持FDM)。
Step 42_4：如果在Step 41中确定的存活PDSCH和之前记录的存活PDSCH当中，超过N个PDSCH有至少1个时域符号交叠，则从集合Q中删除存在时域交叠的该超过N个PDSCH当中的优先级最低的PDSCH，直到可能的FDM复用个数到达UE的FDM复用能力N(N＝2)为止(标注：当N等于2时，不支持超过2个PDSCH的 FDM)。
-Step 43：重复执行Step 41和Step 42，直到集合Q为空，或者直到j等于M(M为UE在一个时隙中支持接收最大PDSCH的个数)。
上述存活的PDSCH可以作为终端需要接收的PDSCH。
需要说明的是，在Step 42_4中，由于FDM PDSCH个数的能力为2，需要删除大于FDM PDSCH个数为2的其它PDSCH，配置ID数值大的为低优先级。删除方法除了实施例中描述的步骤外(缺点是可能造成误删除PDSCH)，也可以描述为如下方法：
方法1：在Step 42_4中，如果在Step 41中确定的存活PDSCH和之前记录的存活PDSCH当中超过2个PDSCH有至少1个时域符号交叠，则删除在Step 41中确定的存活PDSCH，设置j＝j-1(恢复存活PDSCH的计数)，同时恢复Step 42_2和Step42_3删除掉的PDSCH。
方法2：删除Step 42-4，在Step 42_1和Step 42_2之间插入一个步骤Step 42_1a，如下。
Step 42_1a：如果在Step 41中确定的存活PDSCH和之前记录的存活PDSCH当中超过2个PDSCH有至少1个时域符号交叠，则删除Step 41中确定的存活PDSCH，然后跳转执行Step 41。
下面结合一个具体的例子进行说明。图6示例性地示出了本申请另一个实施例在一个时隙中激活的SPS PDSCH在时域和频域上的关系示意图。需要说明的是，图6中横向表示时域，纵向表示频域，若两个SPS PDSCH在纵向上存在交叠，表示两个SPS PDSCH存在资源单元(Resource Element，RE)交叠，若两个SPS PDSCH在横向上存在交叠，表示两个SPS PDSCH存在FDM关系。
图6所示的时隙一共激活了10个SPS PDSCH，其中第一SPS PDSCH集合包括u-1、u-2、u-6、u-8和u-9，第二SPS PDSCH集合包括m-3、m-4、m-5、m-7和m-10，u和m后面的阿拉伯数字表示该SPS PDSCH对应的配置索引(sps-ConfigIndex)，其中，u-1、m-10和u-8存在FDM关系，u-2、u-6与m-7存在FDM关系，u-9和m-4存在FDM关系，等等。
假设UE上报的接收能力N＝2，M＝5。
第一次遍历循环(loop-1)时：选择配置索引sps-ConfigIndex最小的PDSCH(即，u-1)作为第1个存活PDSCH，记录该存活PDSCH类型为单播，删除和该存活PDSCH具有相同数据类型且有FDM关系的u-8，删除和该存活PDSCH有RE交叠的m-10。
第二次遍历循环(loop-2)时：选择配置索引sps-ConfigIndex最小的PDSCH(即，u-2)作为第2个存活PDSCH，记录该存活PDSCH类型为单播，删除和该存活PDSH具有相同数据类型且有FDM关系的u-6。
第三次遍历循环(loop-3)时：选择配置索引sps-ConfigIndex最小的PDSCH(即， m-3)作为第3个存活PDSCH，记录该存活PDSCH类型为多播，删除和该存活PDSCH能够形成超过2个FDM的PDSCH(即，m-5)(注：m-3，m-4，m-5三个PDSCH至少有1个频域符号交叠，删除优先级最低的m-5)。
第四次遍历循环(loop-4)时：选择配置索引sps-ConfigIndex最小的PDSCH(即，m-4)作为第4个存活PDSCH，记录该存活PDSCH类型为组播。
第五次遍历循环(loop-5)时：选择配置索引sps-ConfigIndex最小的PDSCH(即，m-7)作为第5个存活PDSCH，记录该存活PDSCH类型为组播。
在上述各实施例的基础上，作为一种可选实施例，本申请实施例的终端所支持的接收PDSCH的能力还包括：终端确定支持的时分多路复用TDM复用方式的能力以及终端在TDM复用方式下所支持的接收SPS PDSCH的第二最大个数。
需要说明的是，前述的实施例涉及的均为支持的FDM复用方式的能力，相应的，终端在FDM复用方式下所支持的接收SPS PDSCH的最大个数也称为第一最大个数。
当终端同时支持FDM复用方式的能力以及TDM复用方式的能力时，本申请进一步根据两种能力下确定的收发数据的SPS PDSCH更多的一组SPS PDSCH作为最终的用于收发数据的SPS PDSCH。
具体的，确定用于收发数据的SPS PDSCH，还可以包括：若第一最大个数与第二最大个数不同，则获取终端在TDM复用方式下确定的用于收发数据的SPS PDSCH；基于终端在TDM复用方式下确定的用于收发数据的SPS PDSCH的数量和终端在FDM复用方式下确定的用于收发数据的SPS PDSCH数量，将确定的数量更多的一复用方式下的SPS PDSCH作为用于收发数据的SPS PDSCH。
本申请首先会确定终端在两种能力下支持的接收SPS PDSCH的最大个数是否相同，如果相同，则仅基于前述实施例的FDM复用方式下的能力，确定用于收发数据的SPS PDSCH，若不同，则还需要获取终端在TDM复用方式下确定用户收发数据的SPS PDSCH，具体的获取方式可以参照5G R16标准中针对单播的TDM的复用场景UE确定收发数据的SPS PDSCH的方法，在此不再详细描述。
若UE在TDM复用方式下确定的用于收发数据的SPS PDSCH，多于在FDM复用方式下确定的用于收发数据的SPS PDSCH，则将UE在TDM复用方式下确定的用于收发数据的SPS PDSCH，作为最终的用于收发数据的SPS PDSCH。
若UE在TDM复用方式下确定的用于收发数据的SPS PDSCH，少于在FDM复用方式下确定的用于收发数据的SPS PDSCH，则将UE在FDM复用方式下确定的用于收发数据的SPS PDSCH，作为最终的用于收发数据的SPS PDSCH。
本申请实施例提供了一种终端，如图7所示，该终端可以包括：激活资源确定模块101和接收资源确定模块102。
激活资源确定模块101用于确定基站在一个时隙中激活的SPS PDSCH，其中，SPS PDSCH中包括用于承载单播业务的第一SPS PDSCH集合和/或用于承载广播/组 播业务的第二SPS PDSCH集合。

具体地，终端确定支持的频分多路复用FDM复用方式的能力可以包括：在激活的SPS PDSCH当中的、存在FDM复用关系的SPS PDSCH中，支持确定为用于收发数据的SPS PDSCH所承载的业务的类型以及对应各类型的SPS PDSCH的数量。
例如，终端确定支持的FDM复用方式的能力可以包括：对于激活的SPS PDSCH当中的、存在FDM复用关系的SPS PDSCH，支持将1个承载单播业务的SPS PDSCH和最多n-1个承载广播/组播业务的SPS PDSCH确定为用于收发数据的SPS PDSCH；其中，n为在存在FDM复用关系的一组SPS PDSCH中，终端用于收发数据的SPS PDSCH的最大复用数量。
接收资源确定模块102可以包括优先级确定模块和信道确定模块。
在本申请实施例中，优先级确定模块可以用于确定激活的SPS PDSCH的优先级。信道确定模块可以根据激活的SPS PDSCH的优先级从高到低的顺序，结合激活的SPS PDSCH承载的业务的类型以及终端所支持的接收PDSCH的能力，确定用于收发数据的SPS PDSCH。
在本申请另一实施例中，优先级确定模块可以用于分别确定第一SPS PDSCH集合中各SPS PDSCH的优先级以及第二SPS PDSCH集合中各SPS PDSCH的优先级。信道确定模块可以用于根据第一SPS PDSCH集合中各SPS PDSCH的优先级，结合终端所支持的接收PDSCH的能力，从第一SPS PDSCH集合中确定用于收发数据的第一候选SPS PDSCH；根据第二SPS PDSCH集合中各SPS PDSCH的优先级，结合终端所支持的接收PDSCH的能力，从第二SPS PDSCH集合中确定用于收发数据的第二候选SPS PDSCH；从用于收发数据的第一候选SPS PDSCH和用于收发数据的第二候选SPS PDSCH中确定用于收发数据的SPS PDSCH。
在本申请实施例中，终端不仅可以支持FDM复用，还可以支持TDM复用。
例如，终端在FDM复用方式下所支持的接收SPS PDSCH的最大个数可以被称为第一最大个数。
信道确定模块可以用于根据激活的SPS PDSCH的优先级从高到低的顺序，结合激活的SPS PDSCH承载的业务的类型以及终端确定支持的FDM复用方式的能力，从激活的SPS PDSCH中确定用于收发数据的SPS PDSCH，直至确定用户收发数据的SPS PDSCH满足终端所支持的接收SPS PDSCH的第一最大个数。
具体地，优先级确定模块还可以用于确定第一候选SPS PDSCH和第二候选SPS PDSCH中的各SPS PDSCH的优先级。信道确定模块还可以用于根据第一候选SPS PDSCH和第二候选SPS PDSCH中的各SPS PDSCH的优先级从高到低的顺序，确定不超过第一最大个数的用于收发数据的SPS PDSCH。
在本申请的实施例中，确定的用于收发数据的SPS PDSCH之间不存在频域交叠。当确定的用于接收数据的SPS PDSCH中存在至少一个时域交叠的SPS PDSCH组时，可以将时域交叠的SPS PDSCH组中包括的1个承载单播业务的SPS PDSCH和最多n-1个承载广播/组播业务的SPS PDSCH确定为用于收发数据的SPS PDSCH。
终端确定支持的FDM复用方式的能力具体还可以包括：对于激活的SPS PDSCH当中的、存在FDM复用关系的SPS PDSCH，支持将1个承载单播业务的SPS PDSCH和最多n-1个承载广播/组播业务的SPS PDSCH确定为用于收发数据的SPS PDSCH，或者支持将最多n个承载广播/组播业务的SPS PDSCH确定为用于收发数据的SPS PDSCH；其中，n为在存在频域交叠和/或时域交叠的一组SPS PDSCH中，终端确定支持的最大复用数量。
接收资源确定模块102可以用于：确定激活的SPS PDSCH的优先级；根据激活的SPS PDSCH的优先级从高到低的顺序，结合激活的SPS PDSCH承载的业务的类型以及终端所支持的接收PDSCH的能力，确定用于收发数据的SPS PDSCH。
具体地，接收资源确定模块102可以用于：当根据所述顺序确定的当前遍历的SPS PDSCH为单播SPS PDSCH时，从激活的SPS PDSCH的集合中删除与当前遍历的SPS PDSCH时域交叠的SPS PDSCH；当根据所述顺序确定的当前遍历的SPS PDSCH为组播SPS PDSCH，且当前遍历的SPS PDSCH与已确定的用于收发数据的SPS PDSCH中与当前遍历的SPS PDSCH存在FDM关系的SPS PDSCH之和超过第一最大个数时，不将当前遍历的SPS PDSCH确定为用于收发数据的SPS PDSCH，并且从激活的SPS PDSCH的集合中删除当前遍历的SPS PDSCH。
终端所支持的接收PDSCH的能力还可以包括：终端确定支持的时分多路复用TDM复用方式的能力以及终端在TDM复用方式下所支持的接收SPS PDSCH的第二最大个数。
接收资源确定模块102可以用于：当第一最大个数与第二最大个数不同时，获取终端在TDM复用方式下确定的用于收发数据的SPS PDSCH；基于终端在TDM复用方式下确定的用于收发数据的SPS PDSCH的数量和终端在FDM复用方式下确定的用于收发数据的SPS PDSCH数量，将确定的数量更多的复用方式下的SPS PDSCH作为用于收发数据的SPS PDSCH。
本申请实施例提供的终端，通过确定基站在一个时隙中激活的SPS PDSCH，其中，SPS PDSCH中包括用于承载单播业务的第一SPS PDSCH集合和/或用于承载广播/组播业务的第二SPS PDSCH集合；支持实现确定用于收发数据的多类型的SPS  PDSCH，根据激活的SPS PDSCH承载的业务的类型，以及终端所支持的接收PDSCH的能力(例如，终端确定支持的频分多路复用FDM复用方式的能力)，确定用于收发数据的SPS PDSCH，给出了PDSCH支持FDM复用方式时，确定存活PDSCH的方法，可以确保终端能够正确有效地接收SPS PDSCH，从而节约空口资源，提升用户体验。
如图8所示，本申请的实施例还提供了一种SPS PDSCH的确定装置，包括存储器1020、收发机1040、处理器1010。
