为使本申请实施例的目的、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。
图1示出了本申请一个实施例提供的通信系统的架构示意图。该通信系统可以包括：终端10和网络设备20。
终端10在网络设备20所管理的小区内，并且，接入设备所管理的小区内分布一个或多个终端10，也即终端10的数量为一个或者多个。终端10可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端10。在本申请实施例中，有些地方使用“UE”代表“终端10”。
网络设备20是用于为终端10提供无线通信服务的设备。网络设备20可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在5G无线空口技术(New Radio，NR)系统中，称为5G基站(gNodeB或者gNB)。随着通信技术的演进，“基站”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端10提供无线 通信服务的设备统称为网络设备20。
本申请实施例描述的技术方案可以适用于长期演进(Long Term Evolution，LTE)系统，也可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统或者其他通信系统，本申请实施例对此不作限定。
图2示出了本申请一个示例性实施例提供的信息重传方法的流程图。本实施例由网络设备执行。该方法包括如下步骤：
步骤201：向至少一个终端发送第一下行指示信息，第一下行指示信息用于指示至少一个终端激活或释放半静态调度SPS。
网络设备与终端之间基于SPS的模式进行数据传输；而网络设备与终端之间传输数据之前，网络设备向终端发送第一下行指示信息，第一下行指示信息用于指示终端激活SPS，进而后续基于SPS进行数据的传输。其中，第一下行指示信息携带待激活的SPS的标识。
在网络设备与终端之间基于SPS的模式进行数据传输，而网络设备退出这个传输模式时，网络设备向终端发送第一下行指示信息，第一下行指示信息用于指示终端释放SPS，第一下行指示信息中携带待释放的SPS的标识。
第一下行指示信息可以为任一能够指示终端激活SPS的信息；例如，第一下行指示信息可以为DCI或者媒体接入控制(Media Access Control，MAC)信息等，第一下行指示信息还可以为后续演进系统或者其他通信系统中的指示信息，在本申请实施例中，对第一下行指示信息的具体形式不作具体限定。
步骤202：在确定第一终端没有接收到第一下行指示信息的情况下，向第一终端发送第二下行指示信息，第二下行指示信息用于指示第一终端激活或释放SPS，第一终端为至少一个终端中的一个或多个。
第二下行指示信息携带待激活的SPS的标识或者待释放的SPS的标识，并且第二下行指示信息和第一下行指示信息携带的内容相同或者不同。
在本申请实施例中，在下行指示信息用于激活或释放SPS的场景中，网络设备在确定第一终端没有接收到下行指示信息的情况下，向第一终端重传下行指示信息，从而提升了下行指示信息的接收可靠性。
图3示出了本申请一个示例性实施例提供的信息重传方法的流程图。本实施例由网络设备执行。该方法包括如下步骤：
步骤301：按照盲重传次数，向至少一个终端发送息下行指示信息，下行指示信息用于指示至少一个终端激活或释放改变半静态调度SPS，盲重传次数为大于1的整数。
盲重传次数可以根据需要进行设置并更改，在本申请实施例中，对盲重传次数不作具体限定；例如，盲重传次数可以为2、3、4或者5等。另外，盲重传的每个下行指示信息之间的间隔也可以根据需要进行设置并更改，在本申请实施例中，对该间隔不作具体限定；例如，该间隔相同或者不相同。
需要说明的一点是，网络设备先后发送盲重传次数个下行指示信息，每次发送的下行指示信息都是独立的，不依赖于其他的下行指示信息。
在本申请实施例中，在下行指示信息用于激活或释放SPS的场景中，采用盲重传的方式来向至少一个终端发送下行指示信息，从而提升了下行指示信息的接收可靠性。
图4示出了本申请一个示例性实施例提供的信息重传方法的流程图。本实施例由终端执行。该方法包括如下步骤：
步骤401：接收网络设备发送的多个下行指示信息，下行指示信息用于指示终端激活或释放半静态调度SPS，多个下行指示信息为网络设备基于盲重传次数发送的；或多个下行指示信息为网络设备在确定终端没有接收到已发送的下行指示信息的情况下发送的。
在终端启用下行指示信息的反馈的情况下，终端接收到下行指示信息后，向网络设备发送反馈信息，网络设备基于反馈信息，确定终端是否接收到已发送的下行指示信息，进而对下行指示信息进行重传；在终端没有启用下行指示信息的反馈的情况下，终端接收网络设备按照盲重传次数发送的多个下行指示信息。
步骤402：基于目标下行指示信息，激活或释放SPS，目标下行指示信息为多个下行指示信息中的一个。
目标下行指示信息为多个下行指示信息中的第一个下行指示信息；或，
目标下行指示信息为多个下行指示信息中的最后一个下行指示信息；或，
目标下行指示信息为多个下行指示信息中的任意一个下行指示信息；或，
多个下行指示信息携带的内容相同，则目标下行指示信息为多个下行指示信息合并得到的下行指示信息。
在本申请实施例中，在下行指示信息用于激活或释放SPS的场景中，终端接收网络设备发送的多个下行指示信息，从而提升了下行控制信息的接收可靠性。
图5示出了本申请一个示例性实施例提供的信息重传方法的流程图。在本申请实施例中，以下行指示信息用于激活SPS，且终端具有反馈机制，且终端工作在多播场景、广播场景和/或组播场景下为例进行说明。该方法包括如下步骤：
步骤501：网络设备在物理下行控制信道(Physical Downlink Control Channel，PDCCH)上，向至少一个终端发送组共享的第一下行指示信息，第一下行指示信息用于指示至少一个终端激活SPS。
网络设备与终端之间基于SPS的模式进行数据传输；而网络设备与终端之间传输数据之前，网络设备向终端发送第一下行指示信息，第一下行指示信息用于指示终端激活SPS，进而后续基于SPS进行数据的传输。其中，第一下行指示信息携带待激活的SPS的标识。
第一下行指示信息可以为任一能够指示终端激活SPS的信息；例如，第一下行指示信息可以为DCI或者MAC信息等，第一下行指示信息还可以为后续演进系统或者其他通信系统中的指示信息，在本申请实施例中，对第一下行指示信息的具体形式不作具体限定。例如，参见图6，第一下行指示信息为第一DCI，第一DCI为初始激活DCI，用于指示终端激活SPS1，则第一DCI携带SPS1的标识。
组共享的第一下行指示信息是指至少一个终端共享这个第一下行指示信息；在至少一个终端工作在多播场景、组播场景和/或广播场景下的情况下，至少一个终端可以建组，则至少一个终端为同一组的终端；至少一个终端也可以不建组，也即没有组的概念。
需要说明的一点是，发送组共享的第一下行指示信息的PDCCH可以被称为组共享下行控制信道(Group-common PDCCH，GC-PDCCH)，此时网络设备采用GC-PDCCH发送组共享的第一下行指示信息，也即网络设备发送一个第一下行指示信息，第一下行指示信息的接收目标是至少一个终端。在本申请实施例中，通过向至少一个终端发送组共享的第一下行指示信息，从而能够节省下行资源和调度信令开销。
在本申请实施例中终端具有反馈机制，也即终端能够向网络设备发送反馈信息，以告知网络设备，终端对于第一下行指示信息的接收情况。因此，第一下行指示信息还用于指示终端向网络设备发送反馈信息的上行资源。其中，每个终端可以都有专有的上行资源，也可以至少一个终端共享一个上行资源集合。在每个终端都有专有的上行资源的情况下，第一下行指示信息中携带每个终端专属的上行资源的第一指示信息，该上行资源用于终端向网络设备发送反馈信息。该上行资源可以为物理上行控制信道(Physical Uplink Control Channel，PUCCH)或者物理上行共享信道(Physical Uplink Shared Channel，PUSCH)。第一指示信息用于指示该上行资源的资源位置，第一指示信息可以为信息域F1。例如，该上行资源为PUCCH，则第一下行指示信息中携带F1，F1用于指示PUCCH的资源位置，从而使得终端基于该PUCCH的资源位置，在该PUCCH上向网络设备发送反馈信息。
其中，第一下行指示信息携带P比特信息域，P比特信息域用于指示终端专有的上行资源的时域的资源位置和频域的资源位置，以便于终端基于该时域的资源位置和频域的资源位置，确定出终端专有的上行资源。或者，第一下行指示信息携带Q比特信息域，Q比特信息域用于指示终端专有的上行资源的时域的资源位置，频域的资源位置可以通过无线资源控制(Radio Resource Control，RRC)信令进行配置。或者，第一下行指示信息携带Q比特信息与和P比特信息域，分别用于指示终端专有的上行资源的时域资源位置和频域资源位置。网络设备给终端配置的专有的上行资源为上行资源集合中的一个上行资源，该上行资源集合可以被划分为多个子集合，每个子集合中包括至少一个上行资源。网络设备通过RRC信令，给每个终端配置专有的上行资源的频域的资源位置。例如，参见图7，网络设备在PDCCH1上向终端发送第一DCI，第一DCI为初始激活DCI，上行资源集合包括20个上行资源，分别为PUCCH1-PUCCH20，网络设备通过RRC信令指示终端采用20个上行资源中的哪个上行资源进行反馈信息的发送。
需要说明的一点是，发送第一下行指示信息的PDCCH所在时隙与终端专有的上行资源所在的时隙之间的时隙间隔大于预设时隙，从而保证终端有足够的时间，在终端专有的上行资源上发送反馈信息。例如，参见图8，网络设备在PDCCH1上，向终端发送第一下行指示信息，存在两个可用的上行资源，分别为UL1和UL2，由于UL1与PDCCH1之间的时隙间隔a小于预设时隙，而UL2与PDCCH1之间的时隙间隔b大于预设时隙，则网络设备给终端配置的专有的上行资源为UL2。
在至少一个终端共享一个上行资源集合的情况下，第一下行指示信息中携带上行资源集合的第二指示信息，上行资源集合用于至少一个终端向网络设备发送反馈信息。并且，上行资源集合包括M个上行资源，至少一个终端的数量为N，则M和N均为正整数，且M不大于N。在本申请实施例中，由于设置M不大于N，则可以通过设置较少的上行资源供较多的终端来使用从而能够节省上行资源。
需要说明的另一点是，第一下行指示信息还携带第一时隙偏移和/或第一混合重传请求进程标识(HARQ Process ID，HPID偏移；第一时隙偏移为第一下行指示信息所承载的PDCCH的时隙偏移，也即PDCCH与发送数据的PUSCH之间的时隙偏移。第一HPID偏移为第一下行指示信息所承载的PDCCH的HPID偏移，也即，PDCCH与发送数据的PUSCH的HPID偏移。
需要说明的另一点是，第一下行指示信息还携带用于传输数据的物理下行共享信道(Physical Downlink  Shared Channel，PDSCH)的资源位置，以便于终端基于该PDSCH的资源位置，在该PDSCH上接收数据。
对于至少一个终端中的每个终端，均执行步骤502。
步骤502：终端基于对第一下行指示信息的接收情况，向网络设备发送反馈信息。
在第一下行指示信息中携带终端专有的上行资源的第一指示信息的情况下，终端向网络设备发送反馈信息的步骤包括：终端基于第一指示信息，在终端专有的上行资源上，向网络设备发送反馈信息。在第一下行指示信息中携带上行资源集合的第二指示信息的情况下，终端向网络设备发送反馈信息的步骤包括：终端基于第二指示信息，在上行资源集合中的任一上行资源上，向网络设备发送反馈信息。
在终端未接收到第一下行指示信息的情况下，终端并不向网络设备发送反馈信息；在终端接收到第一下行指示信息，但未成功解码第一下行指示信息的情况下，终端向网络设备发送反馈信息，该反馈信息为否定消息(Negative-Acknowledgment，NACK)。在终端接收到第一下行指示信息，且成功解码第一下行指示信息的情况下，终端向网络设备发送反馈信息，该反馈信息为确认消息(Acknowledgment，ACK)。继续参见图6，在终端未接收到第一下行指示信息的情况下，终端在PUCCH1上，向网络设备发送反馈信息。
需要说明的另一点是，在终端启用第一下行指示信息的反馈的情况下，才执行基于对第一下行指示信息的接收情况，向网络设备发送反馈信息的步骤。在终端没有启用第一下行指示信息的反馈的情况下，终端并不向网络设备发送反馈信息。在本申请实施例中，网络设备可以指示终端开启第一下行指示信息的反馈，该过程为：
网络设备向终端发送第一RRC信令，第一RRC信令用于指示终端启用第一下行指示信息的反馈；终端接第一RRC信令，基于第一RRC信令启用第一下行指示信息的反馈；例如，第一RRC信令中携带配置参数MBMS-CS-PDCCH-FB-r17，该配置参数MBMS-CS-PDCCH-FB-r17用于指示终端启用第一下行指示信息的反馈。
或，第一下行指示信息携带第一目标信息域，第一目标信息域用于指示终端启用第一下行指示信息的反馈；终端基于第一目标信息域，启用第一下行指示信息的反馈。其中，第一目标信息域可以为信息域F2。
在本申请实施例中，网络设备不仅可以指示终端开启第一下行指示信息的反馈，还可以指示终端关闭第一下行指示信息的反馈，该过程为：网络设备向终端发送第二RRC信令，第二RRC指令用于指示终端关闭第一下行指示信息的反馈；终端接第二RRC信令，基于第二RRC信令，关闭第一下行指示信息的反馈；或，第一下行指示信息携带第二目标信息域，第二目标信息域用于指示终端关闭第一下行指示信息的反馈；终端基于第二目标信息域，关闭第一下行指示信息的反馈。
需要说明是一点是，网络设备也可以不区分RRC信令，而通过RRC信令携带的内容用于指示终端启用或者关闭第一下行指示信息的反馈；相应的，网络设备向终端发送RRC信令，在该RRC信令携带配置参数MBMS-CS-PDCCH-FB-r17的情况下，终端启用第一下行指示信息的反馈；在该RRC信令没有携带配置参数MBMS-CS-PDCCH-FB-r17的情况下，终端关闭第一下行指示信息反馈。
需要说明的另一点是，网络设备也可以不区分信息域，而通过第一下行指示信息是否携带目标信息域来指示终端启用或者关闭第一下行指示信息的反馈；相应的，在第一下行指示信息中携带目标信息域的情况下，终端启用第一下行指示信息的反馈；在第一下行指示信息中没有携带目标信息域的情况下，终端关闭第一下行指示信息的反馈。例如信息域F1用于指示上行资源的资源位置，信息域F2用于指示终端启用第一下行指示信息的反馈；由于在接入网指示终端启用第一下行指示信息的反馈的前提下，才会携带信息域F1；因此，在第一下行指示信息携带F2的情况下，还需要携带F1；在第一下行指示信息不携带F2的情况下，不需要携带F1。
在本申请实施例中，网络设备能够通过RRC信令或者第一下行指示信息指示终端启用或者关闭第一下行指示信息的反馈，从而能够提高灵活性。
需要说明的另一点是，在网络设备指示终端启用第一下行指示信息的反馈的情况下，网络设备还需要配置上行资源或者上行资源集合；在网络设备指示终端关闭第一下行指示信息的反馈的情况下，网络设备不需要配置上行资源或者上行资源集合。
需要说明的另一点是，在终端接收到第一下行指示信息的情况下，终端基于第一下行指示信息，激活SPS。例如，继续参见图6，在终端接收到第一DCI的情况下，终端激活SPS1。
步骤503：网络设备对反馈信息进行接收。
网络设备在上行资源上对反馈信息进行接收。在每个终端都有专用的上行资源的情况下，对于每个终端，网络设备在该终端专有的上行资源上，对终端的反馈信息进行接收。在每个终端没有专用的上行资源，而是共享上行资源集合的情况下，则网络设备在上行资源集合中的每个上行资源上，对终端的反馈信息进行接收。
需要说明的一点是，由于终端可能发送了反馈信息，终端也有可能没有发送反馈信息；则网络设备有可能能接收到反馈信息，也有可能接收不到反馈信息。网络设备基于反馈信息的接收情况执行步骤504。
步骤504：网络设备基于该反馈信息，确定终端是否接收到第一下行指示信息。
在至少一个终端共享一个上行资源集合的情况下，网络设备可以确定出第一数量，第一数量为至少一个终端中没有接收到第一上行指示信息的数量，以便于后续基于第一数量确定采用哪种方式对信息重传。其中，网络设备确定第一数量的过程为：网络设备确定第三数量，第三数量为上行资源集合中接收到反馈信息为ACK的上行资源的数量；确定N与第三数量的差值，得到第一数量，N为至少一个终端的数量。
由于M不大于N，M为上行资源集合包括的上行资源的数量；在M等于N的情况下，N与第三数量的差值，就是第一数量；在M小于N的情况下，确定N与第三数量的差值，得到第一数量之前，先确定第三数量是否等于M，在第三数量不等于M的情况下，则网络设备确定上行资源集合中的上行资源未被占满，则N与第三数量的差值就是第一数量；在第三数量等于M的情况下，则网络设备确定上行资源集合中的上行资源被占满，网络设备可以默认至少一个终端都接收到了第一下行指示信息，此时不执行步骤505中的信息重传。
在至少一个终端共享一个上行资源集合的情况下，每个终端没有专有的上行资源，网络设备还可以直接确定上行资源集合中的上行资源是否被占满，此时，网络设备不区分具体哪些终端反馈了，哪些终端没有反馈，在上行资源被占满的情况下，则默认至少一个终端都接收到了第一下行指示信息，此时不进行步骤505中的信息重传。在上行资源未被占满的情况下，则执行步骤505中的信息重传。
网络设备在基于反馈信息确定终端没有接收到第一下行指示信息的情况下，执行步骤505中的向终端发送第二下行指示信息的步骤。网络设备在基于反馈信息确定终端接收到第一下行指示信息的情况下，执行步骤506。
步骤505：网络设备在基于反馈信息确定终端没有接收到第一下行指示信息的情况下，在PDCCH上，向至少一个终端发送组共享的第二下行指示信息，第二下行指示信息用于指示终端激活SPS。
第二下行指示信息可以为第二DCI或者第二MAC。第二下行指示信息携带待激活的SPS的标识；并且，第二下行指示信息携带的待激活的SPS的标识与第一下行指示信息携带的待激活的SPS的标识相同或者不同；在第二下行指示信息携带的待激活的SPS的标识与第一下行指示信息携带的待激活的SPS的标识相同的情况下，则第二下行指示信息和第一下行指示信息用于指示终端激活同一个SPS；在第二下行指示信息携带的待激活的SPS的标识与第一下行指示信息携带的待激活的SPS的标识不同的情况下，则第二下行指示信息和第一下行指示信息用于指示终端激活不同的SPS。
同样第二下行指示信息携带第二时隙偏移，并且，第二下行指示信息携带的第二时隙偏移和第一下指示信息携带的第一时隙偏移相同或者不同。另外，第二下行指示信息还携带第二HPID偏移，并且，第二下行指示信息携带的第二HPID和第一下行指示信息携带的第一HPID相同或者不同。
在第二下行指示信息携带的第二时隙偏移和第一下行指示信息携带第一时隙偏移相同，且第二下行指示信息携带的第二HPID偏移和第一下行指示信息携带的第一HPID相同的情况下，则网络设备向终端发送第一下行指示信息的PDCCH与向终端发送数据的PDSCH之间的偏移相同。在第二下行指示信息携带的第二时隙偏移和第一下行指示信息携带第一时隙偏移不同，和/或第二下行指示信息携带的第二HPID偏移和第一下行指示信息携带的第一HPID不同的情况下，则网络设备基于第二时隙偏移和第二HPID偏移，确定发送第二下行指示信息的PDCCH，在该PDCCH上发送第二下行指示信息。
在本申请实施例中，在第一时隙偏移和第二时隙偏移不同，和/或第一HPID偏移和第二HPID偏移不同的情况下，则重传的第二下行指示信息所承载的PDCCH的时域位置可以灵活多变。
例如，参见图9，网络设备在GC-PDCCH1上，向至少一个终端发送组共享的第一DCI，第一DCI为初始激活DCI，且至少一个终端共享第一DCI，第一DCI用于指示至少一个终端激活SPS；至少一个终端在上行资源上向网络设备发送反馈信息；网络设备在GC-PDCCH2上，向至少一个终端发送组共享的第二DCI，第二DCI为补充激活DCI，且至少一个终端共享第二DCI，第二DCI用于指示至少一个终端激活SPS。
在本申请实施例中，对于第二下行指示信息的发送，网络设备同样采用组共享的方式发送，从而提高了效率以及节省了传输资源。
需要说明的一点是，网络设备可以事先配置好，是采用共享的方式，对第二下行指示信息进行发送，还是采用单独发送的方式，对第二下行指示信息进行发送。网络设备还可以根据没有接收到第一指示信息的终端的第一数量，来确定采用哪种方式对第二下行指示信息进行发送，该过程为：
在第一数量不小于预设数量的情况下，网络设备采用组共享的方式，对第二下行指示信息进行发送，也即执行在PDCCH上，向至少一个终端发送组共享的第二下行指示信息的步骤。
例如，继续参见图6，第二下行指示信息为第二DCI，则网络设备在PDCCH2上向终端发送第二DCI，第二DCI为补充激活SPS的DCI。
需要说明的一点是，第二下行指示信息用于指示终端激活SPS，以便于后续网络设备在SPS中的多个PDSCH上，向终端发送数据；因此，网络设备要在PDSCH上，向终端发送数据之前，向终端发送第二下行指示信息。例如，网络设备在PDCCU1上，向终端发送第一下行指示信息，在网络设备在终端专有的 PUCCH1上没有接收到反馈信息的情况下，网络设备在PUCCH1之后且PDSCH1之前，在PDCCH2上向终端发送第二下行指示信息，用于指示终端激活相同的SPS。
本申请实施例能够解决在广播场景、多播场景、组播场景下，由于终端没有收到/无法解码激活SPS的下行指示信息所导致的问题，大大提升了用于激活SPS的下行指示信息的发送/接收可靠性，同时也保证了终端无法接收SPS进程中前几个PDSCH上的数据的问题，提高了系统的可靠性。
步骤506：网络设备在SPS中的多个PDSCH上，向至少一个终端发送数据。
对于每个终端，由于终端已经接收到第一下行指示信息或者第二下行指示信息，则终端已经激活SPS，因此，网络设备在SPS中的多个PDSCH上，向终端发送数据。并且，终端也启用对数据的反馈，也即终端基于在PDSCH上对数据的接收情况，则PDSCH对应的上行链路(UpLink，UL)上进行反馈。
例如，继续参见图6，终端激活的SPS为SPS1，网络设备在PDSCH1上向终端发送数据1，终端在UL1上对数据1的接收情况进行反馈；网络设备在PDSCH2上向终端发送数据2，终端在UL2上对数据2的接收情况进行反馈；网络设备在PDSCHk上向终端发送数据k，终端在ULk上对数据k的接收情况进行反馈。
需要说明的一点是，终端接收网络设备在SPS中的多个PDSCH上发送的数据。终端对于数据的反馈可以采用ACK/NACK的反馈机制，也可以采用仅否定(NACK-only)的反馈机制。
在本申请实施例中，在下行指示信息用于激活SPS的场景中，增加了终端对下行指示信息的反馈机制，网络设备在首次发送下行指示信息以及后续重传下行指示信息，均采用组共享的方式进行发送，从而不仅提升了下行指示信息的接收可靠性，还能够节省传输资源。
图10示出了本申请一个示例性实施例提供的信息重传方法的流程图。在本申请实施例中，以下行指示信息用于激活SPS，且终端具有反馈机制，且终端工作在广播场景和/或多播场景、组播场景下为例进行说明。该方法包括如下步骤：
步骤1001：网络设备在PDCCH上，向至少一个终端发送组共享的第一下行指示信息，第一下行指示信息用于指示终端激活SPS。
步骤1002：终端基于对第一下行指示信息的接收情况，向网络设备发送反馈信息。
步骤1003：网络设备对反馈信息进行接收。
步骤1004：网络设备基于该反馈信息，确定终端是否接收到第一下行指示信息。
需要说明的一点是，步骤1001-1004分别与步骤501-504相似，在此不再赘述。
步骤1005：网络设备在基于反馈信息确定第一终端没有接收到第一下行指示信息的情况下，在PDCCH上，向第一终端发送第一终端专有的第二下行指示信息，第二下行指示信息用于指示第一终端激活SPS。
第一终端为至少一个终端中未接收到第一下行指示信息的终端，且第一终端为至少一个终端中的一个或多个；由于每个终端都有专用的上行资源的情况下，对于每个终端，网络设备在该上行资源上接收到反馈信息，且该反馈信息为ACK，确定该终端成功接收到了第一下行指示信息；网络设备在该上行资源上未接收到反馈信息，或者接收到NACK的反馈信息，确定该终端未成功接收到第一下行指示信息，从而能够确定出哪些终端接收到了第一下行指示信息，哪些终端没有接收到第一下行指示信息，以便于后续有针对性的进行信息重传。
在本申请实施例中，每个终端都有专用的上行资源，从而网络设备可以根据上行资源的资源位置确定每个终端对第一下行指示信息的接收情况，也即能够基于上行资源的资源位置，确定有哪些终端接收到了第一下行指示信息，哪些终端没有接收到第一下行指示信息，从而提高了精准性。
网络设备可以直接向第一终端发送第一终端专有的第二下行指示信息，也可以在第一数量小于预设数量的情况下，网络设备采用单独发送的方式，对第二下行指示信息进行发送，也即执行在PDCCH上，向第一终端发送第一终端专有的第二下行指示信息的步骤。其中，第一数量为至少一个终端中没有接收到第一下行指示信息的终端的数量。
在本步骤中，网络设备对第二下行指示信息采用单独发送的方式进行发送，也即哪个终端没有接收到第一下行指示信息，就向哪个终端发送第二下行指示信息。例如，参见图11，网络设备在GC-PDCCH1上，向至少一个终端发送组共享的第一DCI，第一DCI用于指示至少一个终端激活SPS；至少一个终端在上行资源上向网络设备发送反馈信息；网络设备在终端1专有的PDCCH上，向终端1发送专有的第二DCI，第二DCI用于指示终端1激活SPS，网络设备在终端2专有的PDCCH上，向终端2发送专有的第二DCI，第二DCI用于指示终端2激活SPS，网络设备在终端t专有的PDCCH上，向终端t发送专有的第二DCI，第二DCI用于指示终端t激活SPS。
在本申请实施例中，哪个终端没有接收到第一下行指示信息，接入网就向哪个终端发送第二下行指示信息，从而提高了针对性。
本申请实施例能够解决在广播场景下，由于终端没有收到/无法解码激活SPS的下行指示信息所导致 的问题，大大提升了用于激活SPS的下行指示信息的发送/接收可靠性，同时也保证了终端无法接收SPS进程中前几个PDSCH上的数据的问题，提高了系统的可靠性。
步骤1006：网络设备在SPS中的多个PDSCH上，向至少一个终端发送数据。
需要说明的一点是，步骤1006分别与步骤506相似，在此不再赘述。
在本申请实施例中，在下行指示信息用于激活SPS的场景中，增加了终端对下行指示信息的反馈机制，网络设备在首次发送下行指示信息采用组共享的方式进行发送，而后续重传下行指示信息时，才用单独发送的方式，也即哪个终端没有接收到下行指示信息就给哪个终端发送，从而不仅提升了下行指示信息的接收可靠性，还能够提高重发的针对性。
图12示出了本申请一个示例性实施例提供的信息重传方法的流程图。在本申请实施例中，以下行指示信息用于激活SPS，且终端具有反馈机制，且终端工作在单播场景下为例进行说明。该方法包括如下步骤：

步骤1203：网络设备对反馈信息进行接收。
步骤1204：网络设备基于该反馈信息，确定终端是否接收到第一下行指示信息。
需要说明的一点是，步骤1202-1204分别与步骤502-504相似，在此不再赘述。

第一终端为至少一个终端中的一个或多个。
步骤1206：网络设备在SPS中的多个PDSCH上，向至少一个终端发送数据。
需要说明的一点是，步骤1101-1106分别与步骤501-506相似，在此不再赘述。
在本申请实施例中，在下行指示信息用于激活SPS的场景中，增加了终端对下行指示信息的反馈机制，网络设备在首次发送下行指示信息以及后续重传下行指示信息，均采用单独的方式进行发送，也即给每个终端发送每个终端专有的下行指示信息，从而不仅提升了下行指示信息的接收可靠性，还能够提高有效性。
图13示出了本申请一个示例性实施例提供的信息重传方法的流程图。在本申请实施例中，以下行指示信息用于释放SPS，且终端具有反馈机制为例进行说明。该方法包括如下步骤：
步骤1301：网络设备在SPS中的多个PDSCH上，向至少一个终端发送数据。
本步骤和步骤506相似，在此不再赘述。例如，参见图14，网络设备在SPS1中的PDSCH1-PDSCHk上分别向终端发送数据1-数据k，终端分别在UL1-ULk上对数据1-数据k的接收情况进行反馈。
步骤1302：网络设备在PDCCH上，向每个终端发送终端专有的第一下行指示信息，第一下行指示信息用于指示终端释放SPS。

例如，继续参见图14，终端在PUCCH1上，向网络设备发送反馈信息。

例如，继续参见图14，网络设备在PDCCH2上，向第一终端发送第一终端专有的第二DCI，第二DCI用于指示第一终端释放SPS1，且第二DCI为补充释放DCI。
步骤1302-1306分别与步骤1001-1005相似，在此不再赘述。
步骤1307：在第一终端接收到第二下行指示信息的情况下，第一终端基于第二下行指示信息，释放SPS。
第一终端基于第二下行指示信息携带的待释放的SPS的标识，释放该SPS。
在本申请实施例中，在下行指示信息用于释放SPS的场景中，增加了终端对下行指示信息的反馈机制，网络设备在基于反馈信息确定终端没有接收到下行指示信息的情况下，向终端重传下行指示信息，从而提升了下行指示信息的接收可靠性。

图16示出了本申请一个示例性实施例提供的信息重传方法的流程图。在本申请实施例中，以下行指示信息用于释放SPS，且终端具有反馈机制为例进行说明。该方法包括如下步骤：
步骤1601：网络设备在SPS中的多个PDSCH上，向至少一个终端发送数据。

图17示出了本申请一个示例性实施例提供的信息重传方法的流程图。在本申请实施例中，以下行指示信息用于激活SPS，且网络设备采用盲重传的方式传输下行指示信息为例进行说明。该方法包括如下步骤：
步骤1701：网络设备按照盲重传次数，向至少一个终端发送下行指示信息，下行指示信息用于指示终端激活SPS，盲重传次数为大于1的整数。
终端工作在多播场景、组播场景和/或广播场景下，网络设备采用组共享的方式，对多个下行指示信息进行发送；则网络设备按照盲重传次数，向终端发送下行指示信息的步骤，包括：网络设备按照盲重传次数，在PDCCH上，向至少一个终端发送组共享的所述下行指示信息。终端为单播模式下的一个，网络设备按照盲重传次数，向终端发送下行指示信息的步骤，包括：网络设备按照盲重传次数，在PDCCH上，向终端发送终端专有的下行指示信息。
终端工作在多播场景、组播场景和/或广播场景下，网络设备采用组共享的方式，对第一个下行指示信息进行发送，后续采用单独发送的方式，对后续的下行指示信息进行发送；则网络设备按照盲重传次数，向终端发送下行指示信息的步骤，包括：网络设备在PDCCH上，向至少一个终端发送组共享的下行指示信息；按照P重传次数在PDCCH上，向每个终端发送每个终端专有的下行指示信息。其中，P为不小于1的整数，且P小于盲重传次数。
例如，盲重传次数为2，参见图18，网络设备先后发送两个下行指示信息，第一个下行指示信息为第一DCI，用于指示终端激活SPS1，第二个下行指示信息为第二DCI，第二DCI为补充激活DCI，用于指 示终端激活SPS1。
其中，每个下行指示信息携带的内容相同或不同；例如，每个下行指示信息携带的时隙偏移相同；或，每个下行指示信息携带的时隙偏移不同；每个下行指示信息携带的时隙偏移分别为每个下行指示信息所承载的PDCCH的时隙偏移。另外，每个下行指示信息携带的HPID偏移相同，或，每个下行指示信息携带的HPID偏移不同，每个下行指示信息携带的HPID偏移分别为每个下行指示信息所承载的PDCCH的HPID的偏移。
步骤1702：终端接收网络设备发送的多个下行指示信息，从多个下行指示信息中确定目标下行指示信息。
第一种情况，目标下行指示信息为多个下行指示信息中的第一个下行指示信息；则终端接收到第一个下行指示信息后，存储第一个下行指示信息，后续再接收到下行指示信息后，直接丢弃后续接收到的下行执行信息。例如，盲重传次数为2，且终端成功接收到第一个下行指示信息，再成功接收到第二个下行指示信息，则终端以接收到的第一个下行指示信息为准。
第二种情况，目标下行指示信息为多个下行指示信息中的最后一个下行指示信息；则终端接收到第一个下行指示信息后存储第一个下行指示信息，后续再接收到下行指示信息后，将已存储的下行指示信息更新为最新接收到的下行指示信息。例如，盲重传次数为2，且终端成功接收到第一个下行指示信息，再成功接收到第二个下行指示信息，则终端以最新接收到的第二个下行指示信息为准，更新或者覆盖之前接收到的第一个下行指示信息。
第三种情况，目标下行指示信息为多个下行指示信息中的任意一个下行指示信息；则终端随机存储一个下行指示信息。例如，盲重传次数为2，且终端成功接收到第一个下行指示信息，再成功接收到第二个下行指示信息，则终端随机选择一个下行指示信息。
第四种情况，多个下行指示信息携带的内容相同，则目标下行指示信息为多个下行指示信息合并得到的下行指示信息。例如，盲重传次数为2，且终端成功接收到第一个下行指示信息，再成功接收到第二个下行指示信息，则终端将这两个下行指示信息进行合并。将这两个下行指示信息进行合并的前提是，这两个下行指示信息携带的内容是相同的。
需要说明的一点是，这四种情况可以分开做，只做一个分支即可。
步骤1703：终端基于目标下行指示信息，激活SPS。
终端基于目标下行指示信息携带的待激活的SPS的标识，激活该SPS。
步骤1704：网络设备在SPS中的多个PDSCH上，向终端发送数据。
例如，继续参见图18，网络设备在SPS1中的PDSCH1-PDSCHk上分别向终端发送数据1-数据k，终端分别在UL1-ULk上对数据1-数据k的接收情况进行反馈。
在本申请实施例中，在下行指示信息用于激活SPS场景中，采用盲重传的方式来向终端发送下行指示信息，从而提升了下行指示信息的接收可靠性。
图19示出了本申请一个示例性实施例提供的信息重传方法的流程图。在本申请实施例中，以下行指示信息用于释放SPS，且网络设备采用盲重传的方式传输下行指示信息为例进行说明。该方法包括如下步骤：
步骤1901：网络设备在SPS中的多个PDSCH上，向至少一个终端发送数据。
例如，参见图20，网络设备在SPS1中的PDSCH1-PDSCHk上分别向终端发送数据1-数据k，终端分别在UL1-ULk上对数据1-数据k的接收情况进行反馈。
步骤1902：网络设备按照盲重传次数，向至少一个终端发送下行指示信息，下行指示信息用于指示终端释放SPS。
步骤1903：终端接收网络设备发送的多个下行指示信息，从多个下行指示信息中确定目标下行指示信息。
步骤1902-1903与步骤1701-1702相似，在此不再赘述。例如，盲重传次数为2，继续参见图20，网络设备先后发送两个下行指示信息，第一个下行指示信息为第一DCI，用于指示终端释放SPS1，第二个下行指示信息为第二DCI，第二DCI为补充激活DCI，用于指示终端释放SPS1。
其中，每个下行指示信息携带的内容相同或不同；例如，每个下行指示信息携带的时隙偏移相同；或，每个下行指示信息携带的时隙偏移不同；每个下行指示信息携带的时隙偏移分别为每个下行指示信息所承载的PDCCH的时隙偏移。另外，每个下行指示信息携带的HPID偏移相同，或，每个下行指示信息携带的HPID偏移不同，每个下行指示信息携带的HPID偏移分别为每个下行指示信息所承载的PDCCH的HPID的偏移。
例如，参见图21，网络设备在PDCCH1上向终端发送第一DCI，第一DCI用于指示终端激活SPS，且PDCCH1与PDSCH1之间的偏移为固定偏移c；假设终端接收到了第一DCI，且基于第一DCI已激活 SPS；网络设备向终端发送第二DCI，第二DCI用于指示终端释放SPS。在第一DCI和第二DCI携带相同的时隙偏移和HPID偏移的情况下，则网络设备在PDCCH2上向终端发送第二DCI，且PDCCH2与PDSCH2之间的偏移也为固定偏移c；在第一DCI和第二DCI携带不同的时隙偏移和HPID偏移的情况下，则网络设备在PDCCH3上向终端发送第二DCI，PDCCH2与PDSCH2之间的偏移不是固定偏移c，是非固定偏移d。
步骤1904：终端基于目标下行指示信息，释放SPS。
终端基于目标下行指示信息携带的待释放的SPS的标识，释放该SPS。
在本申请实施例中，在下行指示信息用于释放SPS的场景中，采用盲重传的方式来向终端发送下行指示信息，从而提升了下行指示信息的接收可靠性。
图22示出了本申请一个示例性实施例提供的信息重传方法的流程图。在本申请实施例中，终端对于SPS中的第一个PDSCH上接收到的数据，采用ACK ACK/NACK的反馈机制进行反馈，而对于第一个PDSCH之后的PDSCH上接收到的数据，采用NACK-only的反馈机制进行反馈，从而网络设备基于终端对PDSCH上的数据的反馈机制，来确定是否对下行指示信息进行重传为例进行说明。该方法包括如下步骤：
步骤2201：网络设备向至少一个终端发送第一下行指示信息，第一下行指示信息用于指示终端激活SPS。
在终端接收到第一下行指示信息的情况下，终端激活SPS，并在SPS的第一个PDSCH上接收数据。在终端没有接收到第一下行指示信息的情况下，终端不激活SPS，也不会第一个PDSCH上接收数据。另外，第一下行指示信息中携带终端的专有的上行资源的第一指示信息。
步骤2202：网络设备在SPS的多个PDSCH上向终端发送多个数据。
在终端接收到第一下行指示信息的情况下，终端会在第一个PDSCH上接收数据，在终端在第一个PDSCH上接收到数据的情况下，基于第一指示信息，在终端的专有的上行资源上向接入网发送ACK，此时接入网确定终端接收到了第一下行指示信息以及在第一个PDSCH上发送的数据；在终端在第一个PDSCH上没有接收到数据的情况下，由于终端已经接收到了第一下行指示信息，终端确定网络设备要在第一个PDSCH上发送数据，此时终端向网络设备基于第一指示信息，在终端的专有的上行资源上发送NACK，网络设备基于该NACK确定出终端没有接收到第一个PDSCH上的数据，对第一个PDSCH上的数据进行重传。而对于第一个PDSCH之后的PDSCH上接收到的数据，采用NACK-only的反馈机制进行反馈。ACK/NACK反馈机制所使用的终端专有的上行资源，由高层无线资源控制RRC信令配置给每个终端。
在终端没有接收到第一下行指示信息的情况下，终端不会在第一个PDSCH上接收数据，此时终端不进行任何反馈，此时网络设备在终端的专有的上行资源上不会接收到任何反馈信息，确定出终端未接收到第一下行指示信息。
步骤2203：在网络设备在第一终端的专有的上行资源上没有接收到反馈信息的情况下，网络设备向第一终端发送第二下行指示信息，第二下行指示信息用于指示终端激活SPS，第一终端为指示一个终端中的一个或多个。
在本申请实施例中，无论原有配置/指定的SPS的反馈机制是ACK/NACK还是NACK-only，SPS的第一个PDSCH上的数据采用ACK/NACK的反馈机制，从而网络设备能够确定出终端有没有接收到第一下行指示信息。
在本申请实施例中，在下行指示信息用于激活SPS的场景中，增加了终端对下行指示信息的反馈机制，网络设备在基于反馈信息确定终端没有接收到下行指示信息的情况下，向终端重传下行指示信息，从而提升了下行指示信息的接收可靠性。
