Description

传输信息的方法、终端设备和网络设备 技术领域
本申请涉及通信领域，并且更具体地，涉及传输信息的方法、终端设备和网络设备。
背景技术
物联网(Internet of things，IoT)是“物物相连的互联网”，它将互联网的用户端扩展到了任何物品与物品之间，进行信息交换和通信。该通信方式也称为机器间通信(machine type communications，MTC)，通信的节点称为MTC终端。典型的物联网应用包括可能的应用包括智能电网、智能农业、智能交通、智能家居以及环境检测等各个方面。由于物联网需要应用在多种场景中比如从室外到室内，从地上到地下，因而对物联网的设计提出了很多特殊的要求。
覆盖增强：许多的MTC应用在覆盖较差的环境下，比如电表水表等通常安装在室内甚至地下室等无线网络信号很差的地方，这个时候需要覆盖增强的技术来解决。
支持大量低速率设备：MTC设备的数量要远远大于人与人通信的设备数量，但是传输的数据包很小，并且对延时并不敏感。
非常低的成本：许多MTC应用要求能够以非常低的成本获得并使用MTC设备，从而能够大规模部署。
低能量消耗：在大多数情况下，MTC设备是通过电池来供电的。但是同时在很多场景下，MTC又要求能够使用十年以上而不需要更换电池。这就要求MTC设备能够以极低的电力消耗来工作。
为了满足这些特殊需求，移动通信标准化组织第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)在GERAN#62次全会上通过了一个新的研究课题来研究在蜂窝网络中支持极低复杂度和低成本的物联网的方法，并且在无线接入网络(radio access network，RAN)#69次会议上立项为NB-IOT课题。
在Rel-14窄带物联网(narrow band Internet of thing，NB-IoT)引入了两个混合自动重传请求(hybrid automatic repeat request，HARQ)进程(以下简称two HARQ)的通信技术，，并且2个HARQ进程(HARQ process)是通过两个独立的下行控制信息(downlink control information，DCI)进行调度的。下行数据传输的two HARQ典型的调度如图1所示，在图1中，DCI#1调度传输块(transport block，TB)#1，TB#1承载于窄带物理下行共享信道(narrowband physical downlink shared channel，NPDSCH)#1上，DCI#2调度TB#2，TB#2承载于NPDSCH#2上。上行数据传输的two HARQ典型的调度如图2所示，在图2中，DCI#1调度TB#1，TB#1承载于窄带物理上行共享信道(narrowband physical uplink shared channel，NPUSCH)#1上，DCI#2调度TB#2，TB#2承载于NPUSCH#2上。图1和图2中的后缀名中“#1”，“#2”分别表示两个HARQ进程，“A/N”表示确认 (acknowledgement，ACK)/否定确认(negative acknowledgement，NACK)。
在Rel-16NB-IoT引入调度增强特性，允许使用一个DCI调度多个TB，意味着可以使用一个DCI调度多个HARQ进程。以two HARQ为例，使用一个DCI调度两个HARQ进程的如图3和图4所示，一个DCI同时调度两个NPDSCH或两个NPUSCH。其中，后缀名中“#1”，“#2”分别表示两个HARQ进程，“A/N”表示ACK/NACK。相比Rel-14使用一个DCI调度一个HARQ进程，可以节省DCI资源开销。
但是对于一个DCI调度多个TB场景，目前的协议中尚未规定物理下行控制信道的发送和监听方案。
发明内容
本申请提供传输信息的方法、终端设备和网络设备，明确一个DCI调度多个TB的场景中的物理下行控制信道的发送和监听方案，能够实现物理下行控制信道有效地发送和监听。
第一方面，提供了一种传输信息的方法，所述方法包括：终端设备接收网络设备发送的第一下行控制信息DCI，所述第一DCI调度的传输块TB的数量为N，N为大于或者等于1的整数；所述终端设备在目标时间区间内不监听物理下行控制信道，所述目标时间区间是根据N与第一数值的大小关系确定的。
可选地，所述方法还包括：所述终端设备从所述网络设备接收所述第一DCI调度的N个TB，或者所述终端设备向所述网络设备发送所述第一DCI调度的N个TB。
在上述技术方案中，终端设备接收网络设备发送的第一DCI，而第一DCI调度的TB的数量N与第一数值的大小关系可以体现网络设备后续是否会继续发送DCI，因而终端设备可以根据N与第一数值的大小关系确定不需要监听物理下行控制信道的目标时间区间，能够实现一个DCI调度多个TB的场景中的物理下行控制信道的有效监听。
在一种可能的实现方式中，当N等于所述第一数值时，所述目标时间区间包括从第一时间单元到第二时间单元之间的时间单元，所述第一时间单元为用于承载所述第一DCI的物理下行控制信道传输结束的时间单元，所述第二时间单元为物理上行共享信道或者物理下行共享信道传输开始的时间单元，其中所述物理上行共享信道或所述物理下行共享信道用于承载所述第一DCI调度的第一个TB，或者，所述上行共享信道或所述下行共享信道用于承载所述DCI调度的N个TB。此时目标时间区间不包括第一时间单元和第二时间单元，而是包括第一时间单元与第二时间单元之间的一个或者多个时间单元。
可以理解地，上述的时间单元可以是超帧、帧、半帧、子帧、时隙、符号或采样点等。
在上述技术方案中，在N等于第一数值时，意味着在本次调度中网络设备不会再发送DCI，因此，从第一DCI传输结束的时刻到第一DCI调度的上行或者下行共享信道传输开始的时刻，终端设备可以不再监听物理下行控制信道，进而可以降低终端设备的功耗。
在一种可能的实现方式中，当N等于所述第一数值时，用于承载所述第一DCI调度的N个TB的物理上行共享信道的传输时长大于256毫秒。
可选地，上述传输时长为第四时间单元到第五时间单元之间的时长，所述第四时间单元为用于承载N个TB中第一个TB的物理上行共享信道传输开始的时间单元，所述第五时间单元为用于承载N个TB中最后一个TB的物理上行共享信道传输结束的时间单元， 此时，传输时长包括第四时间单元和第五时间单元。
在Rel-14NB-IoT中DCI到物理上行共享信道之间的调度时延的数值有限，调度时延最大值为64ms，为了防止DCI与物理上行共享信道之间发生传输冲突，因此限制物理上行共享信道的传输时长不能超256ms。在一个DCI调度多个TB的场景中，当N等于第一数值时，意味着在本次调度中网络设备不会再发送DCI，因此不会发生上述传输冲突的情况，因此可以取消物理上行共享信道的传输时长不能超256ms的限制，这样，对于大重复场景也采用一个DCI调度多个TB的方案，提升传输速率。
可以理解地，当N等于所述第一数值时，物理上行共享信道的传输时长可以不受256ms的限制，因此针对实际情况用于承载所述第一DCI调度的N个TB的物理上行共享信道的传输时长可以大于、等于或者小于256ms。
在一种可能的实现方式中，在N小于所述第一数值时，所述目标时间区间包括从第三时间单元到第二时间单元之间的时间单元，所述第三时间单元为物理上行共享信道或者物理下行共享信道传输开始之前的第M个时间单元，所述第二时间单元为物理上行共享信道或者物理下行共享信道传输开始的时间单元，其中，所述第三时间单元在用于承载所述第一DCI的物理下行控制信道传输结束的时间单元之后，所述物理上行共享信道或所述物理下行共享信道在用于承载所述第一DCI传输的物理下行控制信道之后传输，M为大于或者等于2的整数。此时目标时间区间不包括第三时间单元和第二时间单元，而是第三时间单元与第二时间单元之间的一个或者多个时间单元。
可以理解地，上述的时间单元可以是超帧、帧、半帧、子帧、时隙、符号或采样点等。
在上述技术方案中，在N小于第一数值时，意味着网络设备有可能会继续发送DCI，终端设备在上行或者下行共享信道传输开始之前的一段时间内不监听物理下行控制信道，也就是说，终端设备在接收到第一DCI之后的一段时间内仍监听物理下行控制信道，可以降低遗漏DCI的概率。
在一种可能的实现方式中，当N小于所述第一数值时，所述方法还包括：所述终端设备接收所述网络设备发送的第二DCI，从用于承载所述第二DCI调度的TB的物理上行共享信道传输结束的时间单元到用于承载所述第一DCI调度的TB的物理上行共享信道传输开始的时间单元的时长小于或者等于256毫秒。
可选地，上述传输时长为从第四时间单元到第五时间单元的时长，所述第四时间单元为用于承载N个TB中第一个TB的物理上行共享信道传输开始的时间单元，所述第五时间单元为用于承载N个TB中最后一个TB的物理上行共享信道传输结束的时间单元，此时，传输时长包括第四时间单元和第五时间单元。
在一个DCI调度多个TB的场景中，当N小于第一数值时，意味着网络设备有可能会继续再发送DCI。当终端设备继第一DCI之后又收到了第二DCI，那么为了防止DCI与物理上行共享信道之间发生传输冲突，物理上行共享信道的传输时长仍需小于或者等于256ms，以便正确进行数据传输。
在一种可能的实现方式中，所述第一数值为预设值；或者所述第一数值是由所述网络设备配置的。
在一种可能的实现方式中，在所述终端设备接收网络设备发送的第一DCI之前，所述方法还包括：所述终端设备接收所述网络设备发送的配置信息，所述配置信息用于激活调 度增强。
应理解，调度增强也可以表述为“多TB调度”、“一个DCI调度多个TB”、“一个DCI调度多个下行TB”或“一个DCI调度多个上行TB”等。
在上述技术方案中，网络设备通过配置信息通知终端设备是否激活调度增强，可以提高调度的灵活性。
在一种可能的实现方式中，所述第一DCI对应的搜索空间为终端设备特定的搜索空间USS。
考虑到调度增强特性会引入新的DCI格式，如果在CSS中使用，对于网络设备来说，为了传输相同的数据，网络设备需要针对支持调度增强特性的终端设备和不支持调度增强特性的终端设备发送两种格式的DCI，来调度该数据，会增加网络资源开销。对于终端设备来说，终端设备需要盲检测两种格式的DCI，会增加盲检测复杂度。如果限制在USS中使用，USS是UE特定的搜索空间，可以避免上述网络设备侧资源开销增加和终端设备侧盲检测复杂度增加的问题。
在一种可能的实现方式中，所述第一数值为一个DCI支持调度的TB的数量的最大值。
第二方面，本申请提供一种传输信息的方法，所述方法包括：网络设备向终端设备发送第一下行控制信息DCI，所述第一DCI调度的传输块TB的数量N，N为大于或者等于1的整数；所述网络设备在目标时间区间内不发送DCI，所述目标时间区间是根据N与第一数值的大小关系确定的。
可选地，所述方法还包括：所述网络设备向所述终端设备发送所述第一DCI调度的N个TB，或者所述网络设备从所述终端设备接收所述第一DCI调度的N个TB。
在上述技术方案中，网络设备向终端设备发送第一DCI，并且根据第一DCI调度的TB的数量N与第一数值的大小关系确定不需要发送DCI的目标时间区间，这样网络设备可以在该目标区间向其它终端设备发送DCI或者下行数据，能够实现一个DCI调度多个TB的场景中的物理下行控制信道的有效发送，提高资源利用效率。
在一种可能的实现方式中，当N等于所述第一数值时，所述目标时间区间包括从第一时间单元到第二时间单元之间的时间单元，所述第一时间单元为用于承载所述第一DCI的物理下行控制信道传输结束的时间单元，所述第二时间单元为物理上行共享信道或者物理下行共享信道传输开始的时间单元，其中所述物理上行共享信道或所述物理下行共享信道用于承载所述第一DCI调度的第一个TB，或者，所述上行共享信道或所述下行共享信道用于承载所述DCI调度的N个TB。此时目标时间区间不包括第一时间单元和第二时间单元，而是包括第一时间单元与第二时间单元之间的一个或者多个时间单元。
可以理解地，上述的时间单元可以是超帧、帧、半帧、子帧、时隙、符号或采样点等。
在上述技术方案中，在N等于第一数值时，从第一DCI传输结束的时刻到第一DCI调度的上行或者物理下行共享信道传输开始的时刻，网络设备不会再发送DCI，这样终端设备可以不再监听物理下行控制信道，进而可以降低终端设备的功耗，网络设备可以在该目标区间向其它终端设备发送DCI或者下行数据，提高资源利用效率。
在一种可能的实现方式中，当N等于所述第一数值时，用于承载所述第一DCI调度的N个TB的物理上行共享信道的传输时长大于256毫秒。
可选地，上述传输时长为第四时间单元到第五时间单元之间的时长，所述第四时间单 元为用于承载N个TB中第一个TB的物理上行共享信道传输开始的时间单元，所述第五时间单元为用于承载N个TB中最后一个TB的物理上行共享信道传输结束的时间单元，此时，传输时长包括第四时间单元和第五时间单元。
在Rel-14NB-IoT中DCI到物理上行共享信道之间的调度时延的数值有限，调度时延最大值为64ms，为了防止DCI与物理上行共享信道之间发生传输冲突，因此限制物理上行共享信道的传输时长不能超256ms。在一个DCI调度多个TB的场景中，当N等于第一数值时，意味着在本次调度中网络设备不会再发送DCI，因此不会发生上述传输冲突的情况，因此可以取消物理上行共享信道的传输时长不能超256ms的限制，这样，对于大重复场景也采用一个DCI调度多个TB的方案，提升传输速率。

在一种可能的实现方式中，在N小于所述第一数值时，所述目标时间区间包括从第三时间单元到第二时间单元之间的时间单元，所述第三时间单元为物理上行共享信道或者物理下行共享信道传输开始之前的第M个时间单元，所述第二时间单元为物理上行共享信道或者物理下行共享信道传输开始的时间单元，其中，所述第三时间单元在用于承载所述第一DCI的物理下行控制信道传输结束的时间单元之后，所述物理上行共享信道或所述物理下行共享信道在用于承载所述第一DCI传输的物理下行控制信道之后传输，M为大于或者等于2的整数。此时目标时间区间不包括第三时间单元和第二时间单元，而是第三时间单元与第二时间单元之间的一个或者多个时间单元。
可以理解地，上述的时间单元可以是超帧、帧、半帧、子帧、时隙、符号或采样点等。
在上述技术方案中，在N小于第一数值时，意味着网络设备有可能会继续发送DCI，网络设备在上行或者物理下行共享信道传输开始之前的一段时间内不发送DCI，网络设备可以在该时间区间内向其它终端设备发送DCI或者下行数据，提高资源利用效率，网络设备在发送第一DCI之后的一段时间内仍可能会发送DCI，对于终端设备，在接收到第一DCI之后的一段时间内继续监听物理下行控制信道，这样可以降低遗漏DCI的概率。
在一种可能的实现方式中，当N小于所述第一数值时，所述方法还包括：所述网络设备向所述终端设备发送第二DCI，从用于承载所述第二DCI调度的TB的物理上行共享信道传输结束的时间单元到用于承载所述第一DCI调度的TB的物理上行共享信道传输开始的时间单元的时长小于或者等于256毫秒。
可选地，上述传输时长为从第四时间单元到第五时间单元的时长，所述第四时间单元为用于承载N个TB中第一个TB的物理上行共享信道传输开始的时间单元，所述第五时间单元为用于承载N个TB中最后一个TB的物理上行共享信道传输结束的时间单元，此时，传输时长包括第四时间单元和第五时间单元。

在一种可能的实现方式中，所述第一数值为一个DCI支持调度的TB的数量的最大值。
第三方面，本申请提供一种传输信息的方法，所述方法包括：网络设备确定第一下行控制信息DCI；所述网络设备向所述终端设备发送所述第一DCI，所述第一DCI调度的传输块TB的数量N，所述第一DCI调度的N个物理上行共享信道的总传输时长是根据N与第一数值的大小关系确定的，所述N个物理上行共享信道用于承载所述第一DCI调度的N个TB，N为大于或者等于1的整数。
可选地，所述方法还包括：所述网络设备从所述终端设备接收所述第一DCI调度的N个TB。

在上述技术方案中，网络设备通过配置信息通知终端设备是否激活调度增强，可以提高调度的灵活性。
在一种可能的实现方式中，所述第一DCI对应的搜索空间为终端设备特定的搜索空间USS。
考虑到调度增强特性会引入新的DCI格式，如果在CSS中使用，对于网络设备来说，为了传输相同的数据，网络设备需要针对支持调度增强特性的终端设备和不支持调度增强特性的终端设备发送两种格式的DCI，来调度该数据，会增加网络资源开销。对于终端设备来说，终端设备需要盲检测两种格式的DCI，会增加盲检测复杂度。如果限制在USS中使用，USS是UE特定的搜索空间，可以避免上述网络设备侧资源开销增加和终端设备侧盲检测复杂度增加的问题。
在一种可能的实现方式中，所述第一数值为一个DCI支持调度的TB的数量的最大值。
第四方面，本申请提供一种传输信息的方法，所述方法包括：终端设备接收网络设备发送的第一下行控制信息DCI，所述第一DCI调度的传输块TB的数量为N，所述第一DCI调度的N个物理上行共享信道的总传输时长是根据N与第一数值的大小关系确定的，所述N个物理上行共享信道用于承载所述DCI调度的N个TB，N为大于或者等于1的整数；所述终端设备根据所述第一DCI，向所述网络设备发送数据。
可选地，所述方法还包括：所述终端设备向所述网络设备发送所述第一DCI调度的N个TB。
在Rel-14NB-IoT中DCI到物理上行共享信道之间的调度时延的数值有限，调度时延最大值为64ms，为了防止DCI与物理上行共享信道之间发生传输冲突，因此限制物理上行共享信道的传输时长不能超256ms。在一个DCI调度多个TB的场景中，当N等于第一数值时，意味着在本次调度中网络设备不会再发送DCI，因此不会发生上述传输冲突的情况，因此可以取消物理上行共享信道的传输时长不能超256ms的限制；当N小于第一数 值时，意味着网络设备有可能会继续再发送DCI，物理上行共享信道的传输时长仍需小于或者等于256ms，以便正确进行数据传输。因此，上述技术方案中根据N与第一数值的大小关系确定的第一DCI调度的N个物理上行共享信道的总传输时长，提供了一种一个DCI调度多个TB的场景下的物理上行共享信道的传输方案。
在一种可能的实现方式中，所述终端设备在目标时间区间内不监听物理下行控制信道，所述目标时间区间是根据所述大小关系确定的。
在上述技术方案中，终端设备接收网络设备发送的第一DCI，而第一DCI调度的TB的数量N与第一数值的大小关系可以体现网络设备后续是否会继续发送DCI，因而终端设备可以根据N与第一数值的大小关系确定不需要监听物理下行控制信道的目标时间区间，能够实现一个DCI调度多个TB的场景中的物理下行控制信道的有效法发送和监听。
在一种可能的实现方式中，当N等于所述第一数值时，所述传输时长大于256毫秒。
可选地，上述传输时长为第四时间单元到第五时间单元之间的时长，所述第四时间单元为用于承载N个TB中第一个TB的物理上行共享信道传输开始的时间单元，所述第五时间单元为用于承载N个TB中最后一个TB的物理上行共享信道传输结束的时间单元，此时，传输时长包括第四时间单元和第五时间单元。
在Rel-14中为了防止DCI与物理上行共享信道之间发生传输冲突，因此限制物理上行共享信道的传输时长不能超256ms。在一个DCI调度多个TB的场景中，当N等于第一数值时，意味着在本次调度中网络设备不会再发送DCI，因此不会发生上述传输冲突的情况，因此可以取消物理上行共享信道的传输时长不能超256ms的限制，这样，对于大重复场景也采用一个DCI调度多个TB的方案，提升传输速率。
可以理解地，当N等于所述第一数值时，物理上行共享信道的传输时长可以不受256ms的限制，因此针对实际情况用于承载所述第一DCI调度的N个TB的物理上行共享信道的传输时长可以大于、等于或者小于256ms。
在一种可能的实现方式中，当N等于所述第一数值时，所述目标时间区间包括从第一时间单元到第二时间单元之间的时间单元，所述第一时间单元为用于承载所述第一DCI的物理下行控制信道传输结束的时间单元，所述第二时间单元为物理上行共享信道或者物理下行共享信道传输开始的时间单元，其中所述物理上行共享信道或所述物理下行共享信道用于承载所述第一DCI调度的第一个TB，或者，所述上行共享信道或所述下行共享信道用于承载所述DCI调度的N个TB。此时目标时间区间不包括第一时间单元和第二时间单元，而是包括第一时间单元与第二时间单元之间的一个或者多个时间单元。
可以理解地，上述的时间单元可以是超帧、帧、半帧、子帧、时隙、符号或采样点等。
在上述技术方案中，在N等于第一数值时，意味着在本次调度中网络设备不会再发送DCI，因此，从第一DCI传输结束的时刻到第一DCI调度的上行或者物理下行共享信道传输开始的时刻，终端设备可以不再监听物理下行控制信道，进而可以降低终端设备的功耗。
在一种可能的实现方式中，当N小于所述第一数值时，所述方法还包括：所述终端设备接收所述网络设备发送的第二DCI，从用于承载所述第二DCI调度的TB的物理上行共享信道传输结束的时间单元到用于承载所述第一DCI调度的TB的物理上行共享信道传输开始的时间单元的时长小于或者等于256毫秒。
可选地，上述传输时长为第四时间单元到第五时间单元之间的时长，所述第四时间单 元为用于承载N个TB中第一个TB的物理上行共享信道传输开始的时间单元，所述第五时间单元为用于承载N个TB中最后一个TB的物理上行共享信道传输结束的时间单元，此时，传输时长包括第四时间单元和第五时间单元。
在一个DCI调度多个TB的场景中，当N小于第一数值时，意味着网络设备有可能会继续再发送DCI。当终端设备继第一DCI之后又收到了第二DCI，那么为了防止DCI与物理上行共享信道之间发生传输冲突，物理上行共享信道的传输时长仍需小于或者等于256ms，以便正确进行数据传输。
在一种可能的实现方式中，在N小于所述第一数值时，所述目标时间区间包括从第三时间单元到第二时间单元之间的时间单元，所述第三时间单元为物理上行共享信道或者物理下行共享信道传输开始之前的第M个时间单元，所述第二时间单元为物理上行共享信道或者物理下行共享信道传输开始的时间单元，其中，所述第三时间单元在用于承载所述第一DCI的物理下行控制信道传输结束的时间单元之后，所述物理上行共享信道或所述物理下行共享信道在用于承载所述第一DCI传输的物理下行控制信道之后传输，M为大于或者等于2的整数。此时目标时间区间不包括第三时间单元和第二时间单元，而是第三时间单元与第二时间单元之间的一个或者多个时间单元。
可以理解地，上述的时间单元可以是超帧、帧、半帧、子帧、时隙、符号或采样点等。
在上述技术方案中，在N小于第一数值时，意味着网络设备有可能会继续发送DCI，终端设备在上行或者下行共享信道传输开始之前的一段时间内不监听物理下行控制信道，也就是说，终端设备在接收到第一DCI之后的一段时间内仍监听物理下行控制信道，可以降低遗漏DCI的概率。在一种可能的实现方式中，所述最大值为预设值；或者所述最大值是由所述网络设备确定的。
在一种可能的实现方式中，在所述终端设备接收网络设备发送第一DCI之前，所述方法还包括：所述终端设备接收所述网络设备发送的配置信息，所述配置信息用于激活调度增强。
应理解，调度增强也可以表述为“多TB调度”、“一个DCI调度多个TB”、“一个DCI调度多个下行TB”或“一个DCI调度多个上行TB”等。
在上述技术方案中，网络设备通过配置信息通知终端设备是否激活调度增强，可以提高调度的灵活性。
在一种可能的实现方式中，所述第一DCI对应的搜索空间为终端设备特定的搜索空间USS。
考虑到调度增强特性会引入新的DCI格式，如果在CSS中使用，对于网络设备来说，为了传输相同的数据，网络设备需要针对支持调度增强特性的终端设备和不支持调度增强特性的终端设备发送两种格式的DCI，来调度该数据，会增加网络资源开销。对于终端设备来说，终端设备需要盲检测两种格式的DCI，会增加盲检测复杂度。如果限制在USS中使用，USS是UE特定的搜索空间，可以避免上述网络设备侧资源开销增加和终端设备侧盲检测复杂度增加的问题。
在一种可能的实现方式中，所述第一数值为一个DCI支持调度的TB的数量的最大值。

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。
本申请实施例的技术方案可以应用于各种通信系统，只要该通信系统中存在实体可以发送信息，该通信系统也存在其它实体可以接收信息即可。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)、NB-IoT系统、增强型机器类通信(enhanced machine type communication,eMTC)系统、长期演进机器类通信(long term evolution machine type communication,LTE-M或者LTE-MTC)系统等。可以理解地，本申请实施例的技术方案既可以应用于在授权频段使用的通信系统，例 如，LTE、5G、NR等，也可以应用于在非授权频段中使用的LTE、5G、NR等，例如，授权频谱辅助接入(licensed assisted access，LAA)或者基于NR的非授权载波接入(NR-based access to unlicensed spectrum)。
图5是可以应用本申请实施例的一种无线通信系统的示意性架构图。如图5所示，该无线通信系统500可以包括网络设备570和终端设备510-560。终端设备510-560通过无线的方式与网络设备570相连，网络设备570可以发送信息给终端设备510-560中的一个或多个终端设备。此外，终端设备540-560也组成一个通信系统，在该通信系统中，终端设备550可以发送信息给终端设备540和终端设备560中的一个或多个终端设备。终端设备可以是固定位置的，也可以是可移动的。图5只是示意图，该通信系统中还可以包括其它网络设备，如还可以包括无线中继设备和无线回传设备，在图5中未画出。本申请的实施例对该移动通信系统中包括的网络设备和终端设备的数量不做限定。
在无线通信系统500中，终端设备也可以称为终端、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。本申请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，还可以是应用于虚拟现实(virtual reality，VR)、增强现实(augmented reality，AR)、工业控制(industrial control)、无人驾驶(self driving)、远程医疗(remote medical)、智能电网(smart grid)、运输安全(transportation safety)、智慧城市(smart city)以及智慧家庭(smart home)等场景中的无线终端。本申请中将前述终端设备及可应用于前述终端设备的芯片统称为终端设备。应理解，本申请实施例对终端设备所采用的具体技术和具体设备形态不做限定。
在无线通信系统500中，网络设备可以是用于与终端设备通信的设备，该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、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G，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)等。在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，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负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、介质接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。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+AAU发送的。可 以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU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。应理解，在本申请中，网络设备可以是指网络设备本身，也可以是应用于网络设备中完成无线通信处理功能的芯片。
在NB-IoT系统中，对于配置了two HARQ的终端设备，在一个DCI调度一个TB的场景下，以终端设备进行下行传输为例，如图6所示，终端设备在从子帧n+1到子帧n+k-3监听窄带物理下行控制信道(narrowband physical downlink control channel，NPDCCH)，在子帧n+k-2和子帧n+k-1不再监听NPDCCH，以便终端设备为传输窄带物理下行共享信道(narrowband physical downlink shared channel，NPDSCH)或者窄带物理上行共享信道(narrowband physical uplink shared channel，NPUSCH)做准备，其中，子帧n为DCI的结束子帧，子帧n+k为该DCI调度的NPDSCH的起始子帧，此外终端设备进行上行传输与下行传输类似，在此不再赘述。但是对于Rel-16NB-IoT引入调度增强特性，即一个DCI调度多个TB场景，目前的协议中尚未规定物理下行控制信道的发送和监听方案。
针对上述问题，本申请提供了用于传输数据的方法，明确一个DCI调度多个TB的场景中的物理下行控制信道的发送和监听方案，能够实现物理下行控制信道有效地发送和监听。
图7是本申请实施例的信息传输的方法的示意性流程图。图7中的方法可以用于图5所示的无线通信系统中的终端设备和网络设备。在本申请的实施例中，以终端设备和网络设备作为执行主体为例进行说明，应理解，执行主体也可以是应用于终端设备的芯片和应用于网络设备的芯片，本申请实施例不作具体限定。图7中的方法包括以下内容的至少部分内容。
在710中，网络设备向终端设备发送第一DCI，终端设备接收网络设备发送的第一DCI，其中第一DCI调度的TB的数量为N，N为大于或者等于1的整数。
在720中，网络设备在目标时间区间内不发送DCI，终端设备在目标时间区间内不监听物理下行控制信道(not required to monitor NPDCCH)。可以理解地，物理下行控制信道也可以是物理下行控制信道候选，此时720可以表述为网络设备在目标时间区间内不发送DCI，终端设备在目标时间区间内不监听物理下行控制信道候选，本申请实施例对比不做限定。
终端设备和网络设备可以根据第一DCI调度的TB的数量N和第一数值的大小关系，确定目标时间区间。为了方便描述，下文中第一数值用X表示。
本申请实施例对X的具体取值不作具体限定。作为一个示例，X可以是终端设备和网络设备约定好的任意数值，例如，X＝1、2、3、4、5、6、7或8等，可选地，X为大于或者等于2的整数。作为另一个示例，X可以为一个DCI支持调度的TB的数量的最大值。作为又一个示例，X可以为网络设备为终端设备配置的HARQ进程的数量。
可选地，X可以为预设值，例如在协议中体现或者约定；X也可以为网络设备确定并配置给终端设备的，例如，网络设备可以通过RRC信令、MAC信令或DCI等指示。例如，X的取值为{1，2，4，8}中的一个值，或者X的取值为{1，2，3，4，5，6，7，8}中的一个值。
当N＝X时，即第一DCI调度的TB的数量已经达到预设的HARQ进程的数量，或者第一DCI调度的TB的数量已经达到该DCI支持调度的TB的数量的最大值，或者第一DCI调度的TB的数量已经达到第一数值，此时终端设备和网络设备之间不能再进行其他TB的传输，因此从第一DCI传输结束的时刻到第一DCI调度的NPUSCH或者NPDSCH的传输开始的时刻，网络设备可以不再向终端设备发送DCI，终端设备也可以不继续监听物理下行控制信道。
具体地，目标时间区间可以包括从第一时间单元到第二时间单元之间的时间单元，其中第一时间单元为用于承载第一DCI的物理下行控制信道传输结束的时间单元，第二时间单元为物理上行共享信道或者物理下行共享信道传输开始的时间单元，其中所述物理上行共享信道或所述物理下行共享信道用于承载所述第一DCI调度的第一个TB。此时目标时间区间不包括第一时间单元和第二时间单元，而是包括第一时间单元与第二时间单元之间的一个或者多个时间单元。例如，以终端设备进行下行传输为例，如图8所示，其中子帧n为DCI的结束子帧，子帧n+k为该DCI调度的NPDSCH的起始子帧，第一时间单元为子帧n，第二时间单元为子帧n+k，目标时间段为在子帧n和子帧n+k之间的子帧：子帧n+1到子帧n+k-1，即目标时间段包括子帧n+1、子帧n+k-1以及子帧n+1和子帧n+k-1之间的一个或者多个子帧。
或者，上述技术方案还可以表述为：当N＝X时，目标时间区间包括从第一时间单元到第二时间单元之间的时间单元，其中第一时间单元为用于承载第一DCI的物理下行控制信道传输结束的时间单元之后的第一个时间单元，第二时间单元为物理上行共享信道或者物理下行共享信道传输开始的时间单元之前的第一个时间单元，其中所述物理上行共享信道或所述物理下行共享信道用于承载所述第一DCI调度的第一个TB，或者，所述上行共享信道或所述下行共享信道用于承载所述DCI调度的N个TB。此时目标时间区间包括第一时间单元、第二时间单元以及两者之间的一个或者多个时间单元。例如，以终端设备进行下行传输为例，如图8所示，第一时间单元为子帧n+1，第二时间单元为子帧n+k-1，目标时间段为子帧n+1到子帧n+k-1，即目标时间段包括子帧n+1，子帧n+k-1以及子帧n+1和子帧n+k-1之间的一个或者多个子帧。
或者，上述技术方案又可以表述为：当N＝X时，目标时间区间的起始时刻为用于承载所述第一DCI的物理下行控制信道传输结束的时刻，所述目标时间区间的结束时刻为物理上行共享信道或者物理下行共享信道传输开始的时刻，其中所述物理上行共享信道或所述物理下行共享信道用于承载所述第一DCI调度的第一个TB，或者，所述上行共享信道或所述下行共享信道用于承载所述DCI调度的N个TB。例如，以终端设备进行下行传输为例，如图8所示，目标时间区间的起始时刻为DCI结束时间，目标时间区间的结束时刻为NPDSCH起始时间。
应理解，上述物理上行共享信道或所述物理下行共享信道除了承载第一DCI调度的第一个TB，还可以承载其他的TB，本申请实施例不作具体限定。例如，物理上行共享信道或物理下行共享信道用于承载DCI调度的N个TB。
当N<X时，即第一DCI调度的TB的数量小于预设的HARQ进程的数量，或者第一DCI调度的TB的数量小于该DCI支持调度的TB的数量的最大值，或者第一DCI调度的TB的数量小于第一数值，此时终端设备和网络设备之间有可能进行其他TB的传输，因 此第一DCI传输结束后，网络设备可能会向终端设备发送其他DCI，而终端设备也需继续监听物理下行控制信道。
具体地，目标时间区间包括从第三时间单元到第二时间单元之间的时间单元，其中第三时间单元为物理上行共享信道或者物理下行共享信道传输开始之前的第M个时间单元，第二时间单元为物理上行共享信道或者物理下行共享信道传输开始的时间单元，其中，第三时间单元在用于承载所述第一DCI的物理下行控制信道传输结束的时间单元之后，所述物理上行共享信道或所述物理下行共享信道在用于承载所述第一DCI传输的物理下行控制信道之后传输，M为大于或者等于2的整数。此时目标时间区间不包括第三时间单元和第二时间单元，而是第三时间单元与第二时间单元之间的一个或者多个时间单元。例如，以终端设备进行下行传输为例，如图8所示，M＝3，第三时间单元为子帧n+k-3，第二时间单元为子帧n+k，目标时间段为子帧n+k-2到子帧n+k-1，即目标时间段包括子帧n+k-2和子帧n+k-1。
或者，上述技术方案还可以表述为：在N<X时，目标时间区间包括从第三时间单元到第二时间单元之间的时间单元，其中第三时间单元为物理上行共享信道或者物理下行共享信道传输开始之前的第M个时间单元，第二时间单元为物理上行共享信道或者物理下行共享信道传输开始的时间单元的前一个时间单元，其中，第三时间单元在用于承载所述第一DCI的物理下行控制信道传输结束的时间单元之后，所述物理上行共享信道或所述物理下行共享信道在用于承载所述第一DCI传输的物理下行控制信道之后传输，M为大于或者等于1的整数。此时目标时间区间包括第三时间单元、第二时间单元以及两者之间的一个或者多个时间单元。例如，以终端设备进行下行传输为例，如图8所示，M＝2，第三时间单元为子帧n+k-2，第二时间单元为子帧n+k-1，目标时间段为子帧n+k-2到子帧n+k-1，即目标时间段包括子帧n+k-2和子帧n+k-1。
应理解，上述物理上行共享信道或者物理下行共享信道传输开始之前的第M个时间单元可以理解为从物理上行共享信道或者物理下行共享信道传输开始时间单元向前数第M个时间单元，在物理上行共享信道或者物理下行共享信道传输开始时间单元之前，距离物理上行共享信道或者物理下行共享信道传输开始时间单元最近的时间单元为物理上行共享信道或者物理下行共享信道传输开始时间单元之前的第一个时间单元。
还应理解，上述物理上行共享信道或者物理下行共享信道可以是第一DCI调度的，也可以是其他DCI调度的，本申请实施例不作具体限定。可选地，上述物理上行共享信道或物理下行共享信道用于承载第一DCI调度的第一个TB。
可以理解地，上述的时间单元可以是超帧、帧、半帧、子帧、时隙、符号或采样点等，本申请实施例不作具体限定。
可选地，图7所示的方法还包括730，在730中，网络设备向终端设备发送该第一DCI调度的N个TB，终端设备从网络设备接收该第一DCI调度的N个TB；或者终端设备向网络设备发送该第一DCI调度的N个TB，网络设备从终端设备接收该第一DCI调度的N个TB。具体地，对于下行传输，网络设备向终端设备发送该第一DCI调度的N个TB，相应地，步骤710中，终端设备接收到的第一DCI中包括该N个TB的调度信息，终端设备根据该调度信息接收该N个TB。对于上行传输，步骤710中，终端设备接收到的第一DCI中包括该N个TB的调度信息，终端设备根据该调度信息向网络设备发送该第一DCI 调度的N个TB，相应地，网络设备接收该终端设备发送的该N个TB。
本申请实施例对于网络设备何时确定目标时间区间不作限定，例如，网络设备可以在发送第一DCI之前、发送第一DCI之后或者在发送第一DCI的同时确定目标时间区间。
在向终端设备发送第一DCI之前，网络设备确定第一DCI，包括确定第一DCI调度的TB的数量。例如，网络设备根据需要传输的数据的数据量，确定第一DCI调度的TB的数量。
在一些实施例中，在所述终端设备接收网络设备发送的第一DCI之前，网络设备还可以向终端设备发送配置信息，通过所述配置信息指示终端设备激活调度增强，终端设备在接收到所述配置信息后，激活调度增强特性。应理解，调度增强表示一个DCI可以调度至少2个TB。在一些场合，调度增强也可以表述为“多TB调度”、“一个DCI调度多个TB”、“一个DCI调度多个下行TB”或“一个DCI调度多个上行TB”等。
考虑到调度增强特性会引入新的DCI格式，如果在公共搜索空间(common search space，CSS)中使用，对于网络设备来说，为了传输相同的数据，网络设备需要针对支持调度增强特性的终端设备和不支持调度增强特性的终端设备发送两种格式的DCI，来调度该数据，会增加网络资源开销。对于终端设备来说，终端设备需要盲检测两种格式的DCI，会增加盲检测复杂度。如果将调度增强限制在UE特定的搜索空间(UE-specific search space，USS)中使用，可以避免上述网络设备侧资源开销增加和终端设备侧盲检测复杂度增加的问题。也就是说，在调度增强场景下，DCI对应的搜索空间可以为USS。
在Rel-14NB-IoT中，对于配置了two HARQ的场景，DCI到物理上行共享信道之间的调度时延的数值有限，调度时延最大值为64ms，为了防止DCI与物理上行共享信道之间发生传输冲突，因此限制物理上行共享信道的传输时长不能超256ms。如图9所示，第二DCI调度的NPUSCH的传输的结束子帧不得晚于子帧n+k+255，也就是说，第一DCI调度的NPUSCH的传输的起始时刻到第二DCI调度的NPUSCH的传输的结束时刻之间的时长不得超过256毫秒(ms)。对于一个DCI调度多个TB的场景，由于一个DCI可以调度多个TB，调度时延可以重新设计，可以通过增加调度时延的最大值，或者改变调度时延的含义，比如调度时延指示的是DCI传输结束时间到承载该DCI调度的第一个TB的下行共享信道或者上行共享信道传输开始时间之间的时长，可避免DCI与物理上行共享信道之间发生传输冲突，所以可以采用与上述方案不同的方案。
同样，网络设备和终端设备可以根据第一DCI调度的TB的数量N与第一数值的大小关系，确定用于承载N个TB的物理上行共享信道的总传输时长。
本申请实施例对涉及的物理上行共享信道的格式不作具体限定，例如可以为NPUSCH格式1(NPUSCH format 1)、NPUSCH格式2(NPUSCH format 2)等。
图10是本申请另一实施例提供的传输信息的方法的示意性流程图。
在1010中，网络设备确定第一DCI，包括确定第一DCI调度的TB的数量N。
可选地，网络设备可以根据需要传输的数据量和/或剩余传输资源，确定第一DCI调度的TB的数量。
在1020中，网络设备向终端设备发送第一DCI，终端设备接收网络设备发送的第一DCI，所述第一DCI调度的TB的数量N，第一DCI调度的N个物理上行共享信道的总传输时长是根据N与第一数值的大小关系确定的，所述N个物理上行共享信道用于承载所 述第一DCI调度的N个TB，N为大于或者等于1的整数。
可选地，上述传输时长为从第四时间单元到第五时间单元的时长，第四时间单元为用于承载N个TB中第一个TB的物理上行共享信道传输开始的时间单元，第五时间单元为用于承载N个TB中最后一个TB的物理上行共享信道传输结束的时间单元，此时，传输时长包括第四时间单元和第五时间单元。例如，用于承载第一DCI调度的TB的物理上行共享信道传输的开始时间单元为子帧n+k，用于承载所述第二DCI调度的TB的物理上行共享信道传输的结束时间单元为子帧n+k+m，上述传输时长为(m+1)个子帧。
当N＝X时，意味着在本次调度中网络设备不会再发送DCI，因此不会发生上述传输冲突的情况，因此可以取消物理上行共享信道的传输时长不能超256ms的限制。也就是说，当N＝X时，物理上行共享信道的传输时长可以不受256ms的限制，针对实际情况用于承载所述第一DCI调度的N个TB的物理上行共享信道的传输时长可以大于、等于或者小于256ms。例如，以X＝2为例，如图11所示，当N＝2时，网络设备不会再发送第二DCI，第一DCI调度的2个NPUSCH在子帧n+k到子帧n+k+359的时长内传输，总传输时等于360ms，大于256ms。
当N<X时，意味着网络设备有可能会继续再发送DCI，物理上行共享信道的传输时长仍需小于或者等于256ms，以便正确进行数据传输。也就是说，当网络设备在目标时间段之外向终端设备发送第二DCI时，用于承载第二DCI调度的TB的物理上行共享信道传输结束的时间单元到用于承载所述第一DCI调度的TB的物理上行共享信道传输开始的时间单元的时长小于或者等于256毫秒。例如，以X＝2为例，如图11所示，当N＝1时，网络设备发送第二DCI，第一DCI调度的NPUSCH和第二DCI调度的NPUSCH的总传输时长小于或者等于256ms，即在子帧n+k到子帧n+k+255的时长内传输。
在1030中，终端设备向网络设备发送该第一DCI调度的N个TB，网络设备从终端设备接收该第一DCI调度的N个TB。具体地，在1020中，终端设备接收到的第一DCI中包括该N个TB的调度信息，终端设备根据该调度信息向网络设备发送该第一DCI调度的N个TB。相应地，网络设备接收该终端设备发送的该N个TB。
