Description

SPS PDSCH接收方法及装置 技术领域
本申请涉及通信技术领域，具体涉及一种SPS PDSCH接收方法及装置。
背景技术
在NR的下行传输中，网络设备可通过调度半静态调度(semi-persistent scheduling，SPS)物理下行共享信道(Physical Downlink Shared Channel，SPS PDSCH)进行下行数据传输。SPS PDSCH是由无线资源控制(Radio Resource Control，RRC)配置传输周期和配置索引(configuration index),通过激活下行物理控制信息(Downlink Control Information，DCI)激活后进行周期传输。在3GPP Rel-16版本中，最多可同时配置8个SPS PDSCH。当网络设备发送的多个SPS PDSCH在时域上有重叠或者部分重叠，终端设备会保留SPS索引最小的SPS PDSCH，丢弃并删除与其重叠或部分重叠的SPS PDSCH，但是当前丢弃的部分SPS PDSCH的方案只考虑了只有单播业务的场景，没有考虑Rel-17版本中提出的多播广播业务和单播业务混合调度传输的场景。

为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参阅图2，图2为本申请实施例提供的一种SPS PDSCH接收方法流程示意图，应用于如图1所示的无线通信系统。如图2所示，该方法包括如下步骤。
S210、接收多个SPS PDSCH，所述多个SPS PDSCH承载单播业务和/或多播广播业务，所述多个SPS PDSCH中的至少两个SPS PDSCH在时域上重叠或部分重叠。
在本申请实施例中，单播业务和广播业务可共存，网络设备可为单播业务和/或广播业务分配多个SPS PDSCH来进行下行数据的传输。网络设备发送的多个SPS PDSCH占用的资源可能会存在重叠，即，即多个SPS PDSCH之间存在资源重叠，其中，资源重叠可以是时域上的全部重叠，也可以是时域上的部分重叠。
S220、从所述多个SPS PDSCH中丢弃部分所述在时域上重叠或部分重叠的SPS PDSCH。
当多个SPS PDSCH之间存在资源重叠时，多个SPS PDSCH之间会相互干扰(针对其中一组SPS PDSCH而言，该SPS PDSCH在资源重叠部分会受到其他SPS PDSCH的干扰，同时，该SPS PDSCH也会在资源重叠部分对其他SPS PDSCH产生干扰)，从而影响传输的可靠性，针对终端设备而言，终端设备将无法准确得到各SPS PDSCH，从而影响终端设备接收信息的正确性。因此，在本申请中，当终端设备同时接收到多个存在在时域上重叠或部分重叠的SPS PDSCH时，终端设备可根据自身的同时接收的能力丢弃部分在时域上重叠或部分重叠的SPS PDSCH，以避免SPS PDSCH之间的干扰。
可选的，所述从所述多个SPS PDSCH中丢弃部分所述在时域上重叠或部分重叠的SPS PDSCH，包括：
获取SPS PDSCH集合，所述SPS PDSCH集合为所述多个SPS PDSCH中在时域上重叠或部分重叠的SPS PDSCH的集合；从所述SPS PDSCH集合中选取第一SPS PDSCH和/或第二SPS PDSCH；丢弃所述SPS PDSCH集合中与所述第一SPS PDSCH和/或所述第二SPS PDSCH重叠或部分重叠的SPS PDSCH。
其中，当终端设备接收的多个SPS PDSCH中存在在时域上重叠或部分重叠的SPS PDSCH时，终端设备可先丢弃并删除与RRC配置的tdd-UL-DL-ConfigurationCommon或by tdd-UL-DL-ConfigurationDedicated配置的半静态符号重叠的SPS PDSCH。若这次丢弃后仍然存在在时域上重叠或部分重叠的SPS PDSCH，则可以从重叠或部分重叠的SPS PDSCH集合中选取需要保留的SPS PDSCH和/或需要丢弃的SPS PDSCH，从而避免SPS PDSCH之间的干扰。
进一步地，本申请中的终端设备不仅支持单播业务或多播业务的同时接收，也支持广播业务和单播业务混合传输的同时接收。例如，终端设备支持频分复用(frequency-division multiplexing，FDM)的单播业务和多播广播业务的SPS PDSCH传输的同时接收、支持FDM的多个多播广播业务的SPS PDSCH传输的同时接收、支持一个多播广播业务或一个单播业务的SPS PDSCH传输的接收等。因此在接收到存在在时域上重叠或部分重叠的多个SPS PDSCH时，终端设备可根据自身的接收能力和业务类型，丢弃部分在时域上重叠或部分重叠的SPS PDSCH，避免SPS PDSCH之间的相互干扰，从而提供SPS PDSCH传输的可靠性以及终端设备接收信息的正确性。
具体地，终端设备从接收的多个SPS PDSCH中查找出当前重叠或部分重叠的所有激活 的SPS PDSCH，并将其放入到SPS PDSCH集合中。然后终端设备从该SPS PDSCH集合中选取第一次需要保留的第一SPS PDSCH和/或第二SPS PDSCH，丢弃SPS PDSCH集合中与第一SPS PDSCH和/或第二SPS PDSCH重叠或部分重叠的SPS PDSCH。并且终端设备从SPS PDSCH集合中删除与第一SPS PDSCH和/或第二SPS PDSCH重叠或部分重叠的SPS PDSCH、以及第一SPS PDSCH和/或第二SPS PDSCH，以使其可以从该SPS PDSCH集合中选取第二次需要保留的第一SPS PDSCH和/或第二SPS PDSCH，再丢弃SPS PDSCH集合中与第一SPS PDSCH和/或第二SPS PDSCH重叠或部分重叠的SPS PDSCH。然后再从SPS PDSCH集合中删除与第一SPS PDSCH和/或第二SPS PDSCH重叠或部分重叠的SPS PDSCH、以及第一SPS PDSCH和/或第二SPS PDSCH，以从该SPS PDSCH集合中选取第三次需要保留的第一SPS PDSCH和/或第二SPS PDSCH，之后重复此操作，直至SPS PDSCH集合为空集或者操作次数达到了终端设备所支持的每个时隙最大接收的SPS PDSCH的个数。从而得到不会相互干扰的多个SPS PDSCH。
下面，分别从终端设备的不同接收能力对本申请的实现方式进行详细描述。
实施例一
对于终端设备支持FDM的单播业务和多播广播业务的SPS PDSCH传输的同时接收。
可选的，所述多个SPS PDSCH承载单播业务和多播广播业务，所述第一SPS PDSCH为SPS索引最小的承载单播业务的SPS PDSCH，所述第二SPS PDSCH为与所述第一SPS PDSCH重叠或部分重叠的SPS索引最小的承载多播广播业务的SPS PDSCH；或者所述第一SPS PDSCH为SPS索引最小的承载多播广播业务的SPS PDSCH，所述第二SPS PDSCH为与所述第一SPS PDSCH重叠或部分重叠的SPS索引最小的承载单播业务的SPS PDSCH。
其中，对于一组相互重叠的承载单播业务和承载多播广播业务的SPS PDSCH传输，终端设备可以从SPS PDSCH集合中选取SPS索引最小的承载单播业务的SPS PDSCH作为第一SPS PDSCH，然后再从SPS PDSCH集合中选取与第一SPS PDSCH重叠或部分重叠的SPS索引最小的承载多播广播业务的SPS PDSCH作为第二SPS PDSCH。
进一步地，如果能够从SPS PDSCH集合中查找到该第一SPS PDSCH和第二SPS PDSCH，则保留这两个SPS PDSCH，丢弃SPS PDSCH集合中与该两个SPS PDSCH重叠或部分重叠的SPS PDSCH，并从SPS PDSCH集合中删除保留的这两个SPS PDSCH和此次丢弃的SPS PDSCH；如果只查找到了第一SPS PDSCH而没有查找到第二SPS PDSCH，则只保留第一SPS PDSCH，丢弃SPS PDSCH集合中与第一SPS PDSCH重叠或部分重叠的SPS PDSCH，从SPS PDSCH集合中删除保留的第一SPS PDSCH和此次丢弃的SPS PDSCH。然后再重复此动作，再从SPS PDSCH集合中选取第一SPS PDSCH和/或第二SPS PDSCH，直至SPS PDSCH集合为空集或者操作次数达到了终端设备所支持的每个时隙最大接收的SPS PDSCH的个数。
示例性地，终端设备可以从SPS PDSCH集合中选取SPS索引最小的承载多播广播业务的SPS PDSCH作为第一SPS PDSCH，然后再从SPS PDSCH集合中选取与第一SPS PDSCH重叠或部分重叠的SPS索引最小的承载单播业务的SPS PDSCH作为第二SPS PDSCH。如果能够从SPS PDSCH集合中查找到该第一SPS PDSCH和第二SPS PDSCH，则保留这两个SPS PDSCH，丢弃SPS PDSCH集合中与该两个SPS PDSCH重叠或部分重叠的SPS PDSCH，并从SPS PDSCH集合中删除保留的这两个SPS PDSCH和此次丢弃的SPS PDSCH；如果只查找到了第一SPS PDSCH而没有查找到第二SPS PDSCH时，则只保留第一SPS PDSCH，丢弃SPS PDSCH集合中与第一SPS PDSCH重叠或部分重叠的SPS PDSCH，从SPS PDSCH集合中删除保留的第一SPS PDSCH和此次丢弃的SPS PDSCH。然后再重复此动作，再从SPS PDSCH集合中选取该第一SPS PDSCH和第二SPS PDSCH， 直至SPS PDSCH集合为空集或者操作次数达到了终端设备所支持的每个时隙最大接收的SPS PDSCH的个数。
举例说明，如图3a所示，终端设备接收到了SPS索引分别为SPS1、SPS3、SPS4和SPS6的四个SPS PDSCH，该四个SPS PDSCH中包括两个承载单播业务的SPS PDSCH和两个承载多播广播业务的SPS PDSCH，并且这四个SPS PDSCH在时域上存在重叠或部分重叠。按照本申请实施例的方法，终端设备先保留SPS最小的承载单播业务的SPS PDSCH，即SPS1，其次查找与SPS1重叠的SPS最小的承载组播广播业务的SPS PDSCH，即SPS4，则终端设备第一次先保留SPS1和SPS4，然后丢弃并删除与SPS1或SPS4重叠的SPS3。再重复前面的操作，从而保留SPS6。因此终端设备最终保留SPS1、SPS4和SPS6的SPS PDSCH，丢弃SPS3的SPS PDSCH。
又或者，按照本申请实施例的方法，终端设备先保留SPS最小的承载组播广播业务的SPS PDSCH，即SPS4，其次找到与SPS4重叠的SPS索引最小的承载单播业务的SPS PDSCH，即SPS1，则终端设备第一次保留SPS1和SPS4，然后丢弃并删除与SPS1或SPS4重叠的SPS3。再重复前面的操作，保留SPS6。因此终端设备最终保留SPS1、SPS4和SPS6的SPS PDSCH，丢弃SPS3的SPS PDSCH。
又如图3b所示，终端设备接收到了SPS索引分别为SPS1、SPS2、SPS3和SPS4的四个SPS PDSCH，该四个SPS PDSCH中包括三个承载单播业务的SPS PDSCH和一个承载多播广播业务的SPS PDSCH，并且这四个SPS PDSCH在时域上存在重叠或部分重叠。按照本申请实施例的方法，终端设备先保留SPS最小的承载单播业务的SPS PDSCH，即SPS1，其次查找与SPS1重叠的SPS最小的承载组播广播业务的SPS PDSCH，但没有与SPS1重叠的承载组播广播业务的SPS PDSCH，因此终端设备第一次先保留SPS1，然后丢弃并删除与SPS1重叠的SPS3。再重复前面的操作，在剩余的SPS PDSCH集合中保留SPS最小的承载单播业务的SPS PDSCH，即SPS2，其次查找与SPS2重叠的SPS最小的承载组播广播业务的SPS PDSCH，即SPS4。因此终端设备最终保留SPS1、SPS2和SPS4的SPS PDSCH，丢弃SPS3的SPS PDSCH。
在本申请实施例中，终端设备通过保留SPS索引最小的承载单播业务(或承载多播广播业务)的SPS PDSCH以及与其重叠的SPS索引最小的承载多播广播业务(或承载单播业务)的SPS PDSCH，可以在较大程度上找到重叠的并且SPS索引最小的一组或多组FDM的单播业务和多播广播业务的SPS PDSCH传输，从而能够有效地提高传输效率。
实施例二
对于终端设备支持FDM的单播业务和多播广播业务的SPS PDSCH传输的同时接收。
可选的，所述多个SPS PDSCH承载单播业务和多播广播业务，在所述SPS PDSCH集合中存在与承载单播业务的SPS PDSCH重叠或部分重叠的承载多播广播业务的SPS PDSCH时，所述第一SPS PDSCH为与承载多播广播业务的SPS PDSCH重叠或部分重叠的SPS索引最小的承载单播业务的SPS PDSCH，所述第二SPS PDSCH为与所述第一SPS PDSCH重叠或部分重叠的SPS索引最小的承载多播广播业务的SPS PDSCH；或者所述第一SPS PDSCH为与承载单播业务的SPS PDSCH重叠或部分重叠的SPS索引最小的承载多播广播业务的SPS PDSCH，所述第二SPS PDSCH为与所述第一SPS PDSCH重叠或部分重叠的SPS索引最小的承载单播业务的SPS PDSCH；在所述SPS PDSCH集合中不存在与承载单播业务的SPS PDSCH重叠或部分重叠的承载多播广播业务的SPS PDSCH时，所述第一SPS PDSCH为SPS索引最小的承载单播业务或承载多播广播业务的SPS PDSCH。
其中，对于一组相互重叠的承载单播业务和承载多播广播业务的SPS PDSCH传输，终端设备可以从SPS PDSCH集合中选取SPS索引最小的承载单播业务的SPS PDSCH作为第 一SPS PDSCH，然后再从SPS PDSCH集合中选取与第一SPS PDSCH重叠或部分重叠的SPS索引最小的承载多播广播业务的SPS PDSCH作为第二SPS PDSCH。如果从SPS PDSCH集合中查找到该第一SPS PDSCH和第二SPS PDSCH，则保留这两个SPS PDSCH，丢弃SPS PDSCH集合中与该两个SPS PDSCH重叠或部分重叠的SPS PDSCH，并从SPS PDSCH集合中删除保留的这两个SPS PDSCH和此次丢弃的SPS PDSCH。
进一步地，如果从SPS PDSCH集合中未查找到第二SPS PDSCH，则从SPS PDSCH集合中选取SPS索引第二小的承载单播业务的SPS PDSCH作为第一SPS PDSCH，再从SPS PDSCH集合中选取与第一SPS PDSCH重叠或部分重叠的SPS索引最小的承载多播广播业务的SPS PDSCH作为第二SPS PDSCH。如果从SPS PDSCH集合中仍未查找到该第二SPS PDSCH，则从SPS PDSCH集合中选取SPS索引第三小的承载单播业务的SPS PDSCH作为第一SPS PDSCH，再从SPS PDSCH集合中选取与第一SPS PDSCH重叠或部分重叠的SPS索引最小的承载多播广播业务的SPS PDSCH作为第二SPS PDSCH，依据此方法，直至找到两个重叠的或部分重叠的承载单播业务的SPS PDSCH和承载多播广播业务的SPS PDSCH。
进一步地，如果从SPS PDSCH集合中未找到两个重叠的或部分重叠的承载单播业务的SPS PDSCH和承载多播广播业务的SPS PDSCH，则选取SPS索引最小的承载单播业务的SPS PDSCH作为第一SPS PDSCH，保留该第一SPS PDSCH，丢弃SPS PDSCH集合中与该第一SPS PDSCH重叠或部分重叠的SPS PDSCH，并从SPS PDSCH集合中删除保留的这个第一SPS PDSCH和此次丢弃的SPS PDSCH。
最后，然后重复上述此操作，再从SPS PDSCH集合中选取第一SPS PDSCH和/或第二SPS PDSCH，直至SPS PDSCH集合为空集或者操作次数达到了终端设备所支持的每个时隙最大接收的SPS PDSCH的个数。
示例性地，终端设备可以从SPS PDSCH集合中选取SPS索引最小的承载多播广播业务的SPS PDSCH作为第一SPS PDSCH，然后再从SPS PDSCH集合中选取与第一SPS PDSCH重叠或部分重叠的SPS索引最小的承载单播业务的SPS PDSCH作为第二SPS PDSCH。如果从SPS PDSCH集合中查找到该第一SPS PDSCH和第二SPS PDSCH，则保留这两个SPS PDSCH，丢弃SPS PDSCH集合中与该两个SPS PDSCH重叠或部分重叠的SPS PDSCH，并从SPS PDSCH集合中删除保留的这两个SPS PDSCH和此次丢弃的SPS PDSCH。如果从SPS PDSCH集合中未查找到第二SPS PDSCH，则从SPS PDSCH集合中选取SPS索引第二小的承载多播广播业务的SPS PDSCH作为第一SPS PDSCH，再从SPS PDSCH集合中选取与第一SPS PDSCH重叠或部分重叠的SPS索引最小的承载单播业务的SPS PDSCH作为第二SPS PDSCH。如果从SPS PDSCH集合中仍未查找到该第二SPS PDSCH，则从SPS PDSCH集合中选取SPS索引第三小的承载多播广播业务的SPS PDSCH作为第一SPS PDSCH，再从SPS PDSCH集合中选取与第一SPS PDSCH重叠或部分重叠的SPS索引最小的承载单播业务的SPS PDSCH作为第二SPS PDSCH，依据此方法，直至找到两个重叠的或部分重叠的承载多播广播业务的SPS PDSCH和承载单播业务的SPS PDSCH。如果从SPS PDSCH集合中未找到两个重叠的或部分重叠的承载多播广播业务的SPS PDSCH和承载单播业务的SPS PDSCH，则选取SPS索引最小的承载多播广播业务的SPS PDSCH作为第一SPS PDSCH，保留该第一SPS PDSCH，丢弃SPS PDSCH集合中与该第一SPS PDSCH重叠或部分重叠的SPS PDSCH，并从SPS PDSCH集合中删除保留的这个第一SPS PDSCH和此次丢弃的SPS PDSCH。最后，然后重复上述此操作，再从SPS PDSCH集合中选取第一SPS PDSCH和/或第二SPS PDSCH，直至SPS PDSCH集合为空集或者操作次数达到了终端设备所支持的每个时隙最大接收的SPS PDSCH的个数。
举例说明，如图3c所示，终端设备接收到了SPS索引分别为SPS1、SPS2、SPS3、SPS4 和SPS6的五个SPS PDSCH，该五个SPS PDSCH中包括三个承载单播业务的SPS PDSCH和两个承载多播广播业务的SPS PDSCH，并且这五个SPS PDSCH在时域上存在重叠或部分重叠。按照本申请实施例的方法，终端设备先保留SPS最小的承载单播业务的SPS PDSCH，即SPS1，其次查找与SPS1重叠的SPS最小的承载组播广播业务的SPS PDSCH。但没有与SPS1重叠的承载组播广播业务的SPS PDSCH，因此终端设备继续查找SPS第二小的承载单播业务的SPS PDSCH，即SPS2，其次查找与SPS2重叠的SPS最小的承载组播广播业务的SPS PDSCH，即SPS4，则终端设备第一次先保留SPS2和SPS 4，然后丢弃并删除与SPS2和/或SPS 4重叠的SPS1。再重复前面的操作，在剩余的SPS PDSCH集合中保留SPS最小的承载单播业务的SPS PDSCH，即SPS3，其次查找与SPS2重叠的SPS最小的承载组播广播业务的SPS PDSCH，即SPS6。因此终端设备最终保留SPS2、SPS3、SPS4和SPS6的SPS PDSCH，丢弃SPS1的SPS PDSCH。

在本申请实施例中，终端设备通过保留一组重叠或部分重叠的SPS索引最小的承载单播业务(或承载多播广播业务)的SPS PDSCH以及SPS索引最小的承载多播广播业务(或承载单播业务)的SPS PDSCH，可以在最大程度上找到重叠的并且SPS索引最小的一组或多组FDM的单播业务和多播广播业务的SPS PDSCH传输，从而能够有效地提高传输效率。
实施例三
对于终端设备支持FDM的单播业务和多播广播业务的SPS PDSCH传输的同时接收。
可选的，所述多个SPS PDSCH承载单播业务和多播广播业务，在所述SPS PDSCH集合中存在与承载单播业务的SPS PDSCH重叠或部分重叠的承载多播广播业务的SPS PDSCH时，所述第一SPS PDSCH为与承载多播广播业务的SPS PDSCH重叠或部分重叠的起始符号最早或者终止符号最早的承载单播业务的SPS PDSCH，所述第二SPS PDSCH为与所述第一SPS PDSCH重叠或部分重叠的起始符号最早或者终止符号最早的承载多播广播业务的SPS PDSCH；或者所述第一SPS PDSCH为与承载单播业务的SPS PDSCH重叠或部分重叠的起始符号最早或终止符号最早的承载多播广播业务的SPS PDSCH，所述第二SPS PDSCH为与所述第一SPS PDSCH重叠或部分重叠的起始符号最早或者终止符号最早的承载单播业务的SPS PDSCH；在所述SPS PDSCH集合中不存在与承载单播业务的SPS PDSCH重叠或部分重叠的承载多播广播业务的SPS PDSCH时，所述第一SPS PDSCH为起始符号最早或者终止符号最早且承载单播业务或承载多播广播业务的SPS PDSCH。
其中，对于一组相互重叠的承载单播业务和承载多播广播业务的SPS PDSCH传输，如果SPS PDSCH集合中存在与承载单播业务的SPS PDSCH重叠或部分重叠的承载多播广播业务的SPS PDSCH时，则终端设备可以从SPS PDSCH集合中选取与承载多播广播业务的SPS PDSCH重叠或部分重叠且其起始符号最早或者终止符号最早的承载单播业务的SPS PDSCH作为第一SPS PDSCH，然后再从SPS PDSCH集合中选取与第一SPS PDSCH重叠或部分重叠的起始符号最早或者终止符号最早的承载多播广播业务的SPS PDSCH作为第 二SPS PDSCH，保留这两个SPS PDSCH，丢弃SPS PDSCH集合中与该两个SPS PDSCH重叠或部分重叠的SPS PDSCH，并从SPS PDSCH集合中删除保留的这两个SPS PDSCH和此次丢弃的SPS PDSCH。
进一步地，如果SPS PDSCH集合中不存在与承载单播业务的SPS PDSCH重叠或部分重叠的承载多播广播业务的SPS PDSCH，则只保留第一SPS PDSCH或第二SPS PDSCH，丢弃SPS PDSCH集合中与保留的这个SPS PDSCH重叠或部分重叠的SPS PDSCH，并从SPS PDSCH集合中删除保留的这个SPS PDSCH和此次丢弃的SPS PDSCH。然后再重复此动作，再从SPS PDSCH集合中选取该第一SPS PDSCH和第二SPS PDSCH，直至SPS PDSCH集合为空集或者操作次数达到了终端设备所支持的每个时隙最大接收的SPS PDSCH的个数。
举例说明，如图3e所示，终端设备接收到了SPS索引分别为SPS1、SPS2、SPS3、SPS4和SPS6的五个SPS PDSCH，该五个SPS PDSCH中包括三个承载单播业务的SPS PDSCH和两个承载多播广播业务的SPS PDSCH，并且这五个SPS PDSCH在时域上存在重叠或部分重叠。按照本申请实施例的方法，终端设备先保留两个相互重叠且起始符号最早的承载单播业务的SPS PDSCH和承载多播广播业务的SPS PDSCH，即SPS2和SPS4，然后丢弃并删除与SPS2和/或SPS 4重叠的SPS1。再重复前面的操作，在剩余的SPS PDSCH集合中保留两个相互重叠且起始符号最早的承载单播业务的SPS PDSCH和承载多播广播业务的SPS PDSCH，即SPS3和SPS6。因此终端设备最终保留SPS2、SPS3、SPS4和SPS6的SPS PDSCH，丢弃SPS1的SPS PDSCH。
又如图3f所示，终端设备接收到了SPS索引分别为SPS1、SPS2、SPS4和SPS6的四个SPS PDSCH，该四个SPS PDSCH中包括两个承载单播业务的SPS PDSCH和两个承载多播广播业务的SPS PDSCH，并且这四个SPS PDSCH在时域上存在重叠或部分重叠。按照本申请实施例的方法，由于SPS PDSCH集合中没有相互重叠的承载单播业务的SPS PDSCH和承载组播广播业务的SPS PDSCH，因此终端设备先保留起始符号最早的承载单播业务的SPS PDSCH，即SPS2，然后丢弃并删除与SPS2重叠的SPS1。再重复前面的操作，在剩余的SPS PDSCH集合中保留起始符号最早的承载组播广播业务的SPS PDSCH，即SPS6，丢弃并删除与SPS6重叠的SPS4。因此终端设备最终保留SPS2和SPS6的SPS PDSCH，丢弃SPS1和SPS4的SPS PDSCH。
在本申请实施例中，终端设备通过保留一组重叠或部分重叠的起始符号最早(或终止符号最早)的承载组播广播业务(或承载单播业务)的SPS PDSCH和起始符号最早的承载单播业务(或承载组播广播)的SPS PDSCH，能够有效地提高传输效率。并且从最早的SPS PDSCH开始选取，保留了较多的传输机会，兼顾了单播业务和多播广播业务传输的公平性。

其中，对应一组相互重叠多播广播业务的SPS PDSCH传输，终端设备可以从SPS PDSCH集合中选取SPS索引最小的SPS PDSCH作为第一SPS PDSCH，然后再从SPS PDSCH集合中选取与第一SPS PDSCH重叠或部分重叠的SPS索引最小的SPS PDSCH作为第二SPS PDSCH。如果能够从SPS PDSCH集合中查找到该第一SPS PDSCH和第二SPS PDSCH，则保留这两个SPS PDSCH，丢弃SPS PDSCH集合中与该两个SPS PDSCH重叠或部分重叠的SPS PDSCH，并从SPS PDSCH集合中删除保留的这两个SPS PDSCH和此次 丢弃的SPS PDSCH；如果从SPS PDSCH集合中只查找到了第一SPS PDSCH而没有查找到第二SPS PDSCH，则只保留第一SPS PDSCH，丢弃SPS PDSCH集合中与第一SPS PDSCH重叠或部分重叠的SPS PDSCH，从SPS PDSCH集合中删除保留的第一SPS PDSCH和此次丢弃的SPS PDSCH。然后再重复此动作，再从SPS PDSCH集合中选取第一SPS PDSCH和/或第二SPS PDSCH，直至SPS PDSCH集合为空集或者操作次数达到了终端设备所支持的每个时隙最大接收的SPS PDSCH的个数。
举例说明，如图4a所示，终端设备接收到了SPS索引分别为SPS1、SPS2、SPS3和SPS4的四个承载多播广播业务SPS PDSCH，这四个SPS PDSCH在时域上存在重叠或部分重叠。按照本申请实施例的方法，终端设备先保留SPS最小的SPS PDSCH，即SPS1，其次查找与SPS1重叠的SPS最小的SPS PDSCH，即SPS2，然后丢弃并删除与SPS1和/或SPS2重叠的SPS4，则终端设备第一次先保留SPS1和SPS4。再重复前面的操作，第二次保留SPS3。因此终端设备最终保留SPS1、SPS2和SPS3的SPS PDSCH，丢弃SPS4的SPS PDSCH。
在本申请实施例中，终端设备通过保留一组SPS索引最小的承载多播广播业务的SPS PDSCH，可以在较大程度上找到重叠的并且SPS索引最小的一组或多组FDM的多播广播业务的SPS PDSCH传输，从而能够有效地提高传输效率。
实施例五
对于支持FDM的多个多播广播业务的SPS PDSCH传输的同时接收。
可选的，所述多个SPS PDSCH承载多个多播广播业务，所述第一SPS PDSCH为起始符号最早或者终止符号最早的SPS PDSCH，所述第二SPS PDSCH为与所述第一SPS PDSCH重叠或部分重叠的起始符号最早或者终止符号最早的SPS PDSCH。
其中，对应一组相互重叠多播广播业务的SPS PDSCH传输，终端设备先从SPS PDSCH集合中选取起始符号最早或者终止符号最早的SPS PDSCH作为第一SPS PDSCH，然后再从SPS PDSCH集合中选取与第一SPS PDSCH重叠或部分重叠的起始符号最早或者终止符号最早的SPS PDSCH作为第二SPS PDSCH。如果能够从SPS PDSCH集合中查找到该第一SPS PDSCH和第二SPS PDSCH，则保留这两个SPS PDSCH，丢弃SPS PDSCH集合中与该两个SPS PDSCH重叠或部分重叠的SPS PDSCH，并从SPS PDSCH集合中删除保留的这两个SPS PDSCH和此次丢弃的SPS PDSCH；如果从SPS PDSCH集合中只查找到了第一SPS PDSCH而没有查找到第二SPS PDSCH，则只保留第一SPS PDSCH，丢弃SPS PDSCH集合中与第一SPS PDSCH重叠或部分重叠的SPS PDSCH，从SPS PDSCH集合中删除保留的第一SPS PDSCH和此次丢弃的SPS PDSCH。然后再重复此动作，再从SPS PDSCH集合中选取该第一SPS PDSCH和/或第二SPS PDSCH，直至SPS PDSCH集合为空集或者操作次数达到了终端设备所支持的每个时隙最大接收的SPS PDSCH的个数。
举例说明，如图4b所示，终端设备接收到了SPS索引分别为SPS1、SPS2、SPS3和SPS4的四个承载多播广播业务SPS PDSCH，这四个SPS PDSCH在时域上存在重叠或部分重叠。按照本申请实施例的方法，终端设备先保留起始符号最早的SPS PDSCH，即SPS4，其次查找与SPS4重叠的起始符号最早的SPS PDSCH，即SPS3，然后丢弃并删除与SPS3和/或SPS4重叠的SPS1，则终端设备第一次先保留SPS3和SPS4，再重复前面的操作，第二次保留SPS3。因此终端设备最终保留SPS2、SPS3和SPS4的SPS PDSCH，丢弃SPS1的SPS PDSCH。
在本申请实施例中，终端设备通过保留一组起始符号最早的承载多播广播业务的SPS PDSCH，能够有效地提高传输效率。并且从最早的SPS PDSCH开始选取，保留了较多的传输机会，兼顾了单播业务和多播广播业务传输的公平性。
实施例六
对于支持一个多播广播业务或一个单播业务的SPS PDSCH传输的接收。
可选的，所述多个SPS PDSCH承载单播业务或多播广播业务，所述第一SPS PDSCH为SPS索引最小的承载单播业务的SPS PDSCH，所述第二SPS PDSCH为与所述第一SPS PDSCH重叠或部分重叠的SPS索引最小的承载多播广播业务的SPS PDSCH。
其中，当在终端设备的能力不支持FDM的单播业务和广播业务的SPS PDSCH传输同时接收时，即终端设备一次只能接收1个广播业务或者单播业务的SPS PDSCH时，终端设备可以从SPS PDSCH集合中选取SPS索引最小的一个承载单播业务的SPS PDSCH作为第一SPS PDSCH，选取SPS索引最小的一个承载多播广播业务的SPS PDSCH作为第二SPS PDSCH。如果从SPS PDSCH集合中查找到的第一SPS PDSCH和第二SPS PDSCH不重叠或不部分重叠，则保留这两个SPS PDSCH，丢弃SPS PDSCH集合中与该两个SPS PDSCH重叠或部分重叠的SPS PDSCH，并从SPS PDSCH集合中删除保留的这两个SPS PDSCH和此次丢弃的SPS PDSCH。如果从SPS PDSCH集合中查找到的第一SPS PDSCH和第二SPS PDSCH重叠或部分重叠，则只保留第一SPS PDSCH或第二SPS PDSCH，或者只保留第一SPS PDSCH和第二SPS PDSCH之间SPS索引最小的那个SPS PDSCH，丢弃SPS PDSCH集合中与保留的这个SPS PDSCH重叠或部分重叠的SPS PDSCH，并从SPS PDSCH集合中删除保留的这个SPS PDSCH和此次丢弃的SPS PDSCH。然后再重复此动作，再从SPS PDSCH集合中选取该第一SPS PDSCH和/或第二SPS PDSCH，直至SPS PDSCH集合为空集或者操作次数达到了终端设备所支持的每个时隙最大接收的SPS PDSCH的个数。
举例说明，如图5a所示，终端设备接收到了SPS索引分别为SPS1、SPS2、SPS3、SPS4和SPS5的五个SPS PDSCH，该五个SPS PDSCH中包括三个承载单播业务的SPS PDSCH和两个承载多播广播业务的SPS PDSCH，并且这五个SPS PDSCH在时域上存在重叠或部分重叠。按照本申请实施例的方法，终端设备先保留SPS索引最小的一个承载单播业务的SPS PDSCH和SPS索引最小的一个承载多播广播业务的SPS PDSCH，即SPS1和SPS4，由于SPS1与SPS4相互重叠，因此至保留SPS索引最小的一个承载单播业务的SPS PDSCH，即SPS1，然后丢弃并删除与SPS1重叠的SPS2、SPS4和SPS5。再重复前面的操作，在剩余的SPS PDSCH集合中保留SPS3。因此终端设备最终保留SPS1、和SPS3的SPS PDSCH，丢弃SPS2、SPS4和SPS5的SPS PDSCH。
又例如，如图5a所示，按照本申请实施例的方法，终端设备先保留SPS索引最小的一个承载单播业务的SPS PDSCH和SPS索引最小的一个承载多播广播业务的SPS PDSCH，即SPS1和SPS4，由于SPS1与SPS4相互重叠，因此至保留SPS索引最小的一个承载多播广播业务的SPS PDSCH，即SPS4，然后丢弃并删除与SPS4重叠的SPS1和SPS2。再重复前面的操作，在剩余的SPS PDSCH集合中保留SPS索引最小的一个承载单播业务的SPS PDSCH和SPS索引最小的一个承载多播广播业务的SPS PDSCH，即SPS3和SPS5。因此终端设备最终保留SPS3、SPS4和SPS5的SPS PDSCH，丢弃SPS1和SPS2的SPS PDSCH。
在本申请实施例中，终端设备通过保留SPS索引最小的承载单播业务的SPS PDSCH和/或SPS索引最小的承载多播广播业务的SPS PDSCH，可以在较大程度上找到SPS索引最小的一组或多组FDM的单播业务和/或多播广播业务的SPS PDSCH传输，从而能够有效地提高传输效率，并且保证了单播业务和多播广播业务传输的均衡性。
实施例七

可选的，所述多个SPS PDSCH承载单播业务或多播广播业务，所述第一SPS PDSCH 或所述第二SPS PDSCH为SPS索引最小的SPS PDSCH。
其中，终端设备一次只能接收1个广播业务或者单播业务的SPS PDSCH时，终端设备可以从SPS PDSCH集合中选取SPS索引最小的一个的SPS PDSCH进行保留，然后丢弃SPS PDSCH集合中与保留的这个SPS PDSCH重叠或部分重叠的SPS PDSCH，并从SPS PDSCH集合中删除保留的这个SPS PDSCH和此次丢弃的SPS PDSCH。最后再重复此动作，再从SPS PDSCH集合中选取该第一SPS PDSCH和/或第二SPS PDSCH，直至SPS PDSCH集合为空集或者操作次数达到了终端设备所支持的每个时隙最大接收的SPS PDSCH的个数。
举例说明，如图5b所示，终端设备接收到了SPS索引分别为SPS1、SPS2、SPS3和SPS4的四个SPS PDSCH，该四个SPS PDSCH中包括两个承载单播业务的SPS PDSCH和两个承载多播广播业务的SPS PDSCH，并且这四个SPS PDSCH在时域上存在重叠或部分重叠。按照本申请实施例的方法，终端设备先保留SPS索引最小的SPS PDSCH，即SPS1；然后丢弃并删除与SPS1重叠的SPS2和SPS3。再重复前面的操作，在剩余的SPS PDSCH集合中保留SPS索引最小的SPS PDSCH，即SPS4。因此终端设备最终保留SPS1和SPS4的SPS PDSCH，丢弃SPS2和SPS3的SPS PDSCH。
在本申请实施例中，终端设备通过优先保留SPS索引最小的SPS PDSCH，可以在较大程度上找到SPS索引最小的SPS PDSCH传输，从而能够有效地提高传输效率。
可以看出，本申请提出了一种SPS PDSCH接收方法，接收多个SPS PDSCH，该多个SPS PDSCH承载单播业务和/或多播广播业务，该多个SPS PDSCH中的至少两个SPS PDSCH在时域上重叠或部分重叠；从多个SPS PDSCH中丢弃部分在时域上重叠或部分重叠的SPS PDSCH，提供了一种在终端设备同时接收到通过SPS PDSCH传输的多播广播业务和/或单播业务时，丢弃部分在时域上有重叠或者部分重叠的SPS PDSCH的技术方案。
