为了更好地描述本申请实施例的原理和具体实施方式，以下对本申请实施例的相关技术内容进行描述。
下行控制信息(downlink control information，DCI)：对于有下行业务的终端设备，网络设备可以通过下行授权DCI为终端设备调度物理下行共享信道(physical downlink shared channel，PDSCH)的传输。下行授权DCI中包括物理上行控制信道(physical uplink control channel，PUCCH)资源的指示信息，终端设备在收到PDSCH后，终端设备可以确定该PDSCH的译码结果(ACK或NACK信息)，并通过该PUCCH资源将译码结果反馈给网络设备。在NR系统中，PDSCH调度的DCI格式包括DCI格式1_0，DCI格式1_1，DCI格式1_2。下面，分别结合表1、表2和表3介绍每种DCI格式的DCI中包括的信息域以及比特大小。
表1
Figure PCTCN2020077279-appb-000001
在表1中，下行链路分配索引、预定PUCCH的TPC命令、PUCCH资源指示、PDSCH到HARQ反馈定时指示信息域用于反馈PDSCH传输对应的HARQ-ACK信息。
表2

Figure PCTCN2020077279-appb-000003
在表2中，下行链路分配索引、预定PUCCH的TPC命令、PUCCH资源指示、PDSCH到HARQ反馈定时指示、单次HARQ-ACK请求、PDSCH群索引、新反馈指示、请求的PDSCH组数信息域用于反馈PDSCH传输对应的HARQ-ACK信息。
表3
Figure PCTCN2020077279-appb-000004
Figure PCTCN2020077279-appb-000005
在表3中，下行链路分配索引、预定PUCCH的TPC命令、PUCCH资源指示、PDSCH-to-HARQ_反馈定时指示信息域用于反馈PDSCH传输对应的HARQ-ACK信息。
在上述表2-表3中，对于DCI格式1_1和DCI格式1_2，DCI中包括的多数信息域的大小可以是网络设备通过高层参数(例如无线资源控制(radio resource control，RRC)信令)配置的。例如，DCI格式中的信息域对应的比特数为0时，表示该DCI格式中可以不包括该信息域。
在上述表1-表3中，若网络设备和终端设备之间的通信传输是发生在共享频谱上(例如，非授权频谱上)，或者终端设备通过非授权频谱上的资源发送PUCCH时，上述DCI中可以包括信道接入指示(ChannelAccess-CPext)信息域；若网络设备和终端设备之间的通信传输是发生在授权频谱上时，上述DCI中不包括信道接入指示(ChannelAccess-CPext)信息域。
对于有上行业务的终端设备，网络设备可以通过上行授权DCI为终端设备调度物理上行共享信道(physical uplink shared channel，PUSCH)的传输。上行授权DCI中可以包括确定PUSCH资源的指示信息，终端设备可以根据上行授权DCI在该确定的PUSCH资源上传输PUSCH。在NR系统中，调度PUSCH传输的DCI格式包括DCI格式0_0，DCI格式0_1，或DCI格式0_2。
混合自动重传请求(hybrid automatic repeat request，HARQ)机制：HARQ机制为媒体接入控制(medium access control，MAC)层的重传机制，通过HARQ机制可以对传输丢失或者传输出错的数据进行重传。HARQ进程包括上行HARQ进程和下行HARQ进程，上行HARQ进程和下行HARQ进程相互独立。
在相关技术中(例如NR系统中)，通常采用停等协议(stop-and-wait protocol)进行HARQ重传。在采用等停协议进行HARQ重传时，发送端通过一个HARQ进程发送传输块(transport block，TB)以后，就停下来等待接收端发送的确认信息(确认信息用于指示接收端是否正确接收传输块TB)，在该等待的过程中，发送端无法通过该HARQ进程向终端设备发送其它TB。在接收端接收到一个HARQ进程对应的TB以后，接收端对TB进行译码，若译码成功，则接收端向发送端发送肯定应答确认信息(ACK)，若译码失败，则接收端向发送端发送否定应答确认信息(NACK)。若发送端接收到HARQ进程对应的ACK信息，则发送端可以通过该HARQ进程向接收端发送其它TB。若发送端接收到HARQ进程对应的NACK，或者发送端长时间内未接收到任何响应，则发送端可以通过该HARQ进程重传TB。在上述过程中，当发送端为网络设备时，接收端可以为终端设备。当发送端为终端设备时，接收端可 以为网络设备或另一终端设备。
在相关技术中，网络设备可以通过例如无线资源控制(Radio Resource Control，RRC)信令半静态配置等方式向终端设备指示上下行最大的HARQ进程数。如果网络设备未提供相应的配置参数，则下行的HARQ进程数可以为缺省值例如为8。上行每个载波支持的最大HARQ进程数可以为16。其中，每个HARQ进程对应一个HARQ进程号(HARQ process number，HPN)，HARQ进程号也称为HARQ ID(Identity，标识)。
图1以下行传输为例，对HARQ进程数和往返传输时间RTT如何影响数据传输的吞吐量进行说明。如图1所示，终端设备被配置的最大HARQ进程数为16，16个HARQ进程包括HARQ0至HARQ15，16个HARQ进程可在16ms内被连续调度。其中，对于一个HARQ进程例如HARQ0，其被调度后，在数据往返过程中该HARQ进程HARQ0处于停等状态，不能用于传输其他数据，因此，在图1所示的终端设备最大HARQ进程数为16的场景中，可能存在以下几种情况：
如果RTT小于16ms，在HARQ0被调度后的RTT范围内，在有业务数据要传输时，该终端设备总是可以有并行的HARQ进程(HARQ1至HARQ15中的一个或多个)来进行数据传输；在HARQ0被调度后的时间超过RTT时，HARQ0可再次用于传输数据。因此，数据可以在由HARQ0至HARQ15构成的HARQ实体上连续传输，不影响该终端设备的最大吞吐量。另外，如果RTT等于16ms，且终端设备被配置的最大HARQ进程数为16，同理可知，总是有HARQ进程可传输业务数据；但是，如果终端设备被配置的最大HARQ进程数小于16，则在有业务数据要传输时，有可能所有HARQ进程都处于等待网络设备反馈的状态，则此时没有HARQ进程可用，影响终端设备数据传输的吞吐量。
如果RTT远大于16ms，例如NTN系统中的RTT可达600ms，实际中可能的情况是：终端设备的所有HARQ进程都处于未收到网络设备反馈的状态，则终端设备在有业务数据待传输时，将在很长时间内没有HARQ进程可用，严重影响终端设备数据传输的吞吐量。
也就是说，在NTN系统的应用场景或类似的其他场景中，由于RTT大幅增大，导致终端设备配置的HARQ进程数与系统RTT不匹配，最终导致系统性能下降。
为了解决上述技术问题，本申请实施例提出一种数据传输方法，为了便于理解本申请所示的数据传输方法，首先，结合图2A-图2B，对本申请中的通信系统的架构进行说明。
图2A为本申请实施例提供的一种通信系统的架构示意图。请参见图2A，包括终端设备201和卫星202，终端设备201和卫星202之间可以进行无线通信。终端设备201和卫星202之间所形成的网络还可以称为NTN。在图1所示的通信系统的架构中，卫星202具有基站的功能，终端设备201和卫星202之间可以直接通信。在系统架构下，可以将卫星202称为网络设备。
图2B为本申请实施例提供的另一种通信系统的架构示意图。请参见图2B，包括终端设备301、卫星302和基站303，终端设备301和卫星302之间可以进行无线通信，卫星302与基站303之间可以通信。终端设备301、卫星302和基站303之间所形成的网络还可以称为NTN。在图2所示的通信系统的架构中，卫星302不具有基站的功能，终端设备101和基站303之间的通信需要通过卫星302的中转。在该种系统架构下，可以将基站103称为网络设备。
需要说明的是，图2A-图2B只是以示例的形式示意本申请所适用的系统，当然，本申请实施例所示的方法还可以适用于其它系统，例如，5G通信系统、LTE通信系统等，本申请实施例对此不作具体限定。本申请实施例可以包括下述内容中的至少部分内容。
在本申请中，在RTT较大的场景(例如NTN)下，为了提高终端设备和网络设备之间的数据传输效率，针对终端设备的下行HARQ进程，网络设备可以向终端设备配置或指示该下行HARQ进程对应的HARQ反馈功能状态。例如，将下行HARQ进程对应的HARQ反馈功能状态配置为非使能态。相应的，若终端设备确定该下行HARQ进程对应的HARQ反馈功能状态为非使能态，则终端设备被下行授权调度在该下行HARQ进程上接收到数据后，不根据该下行授权对该HARQ进程进行HARQ-ACK信息反馈。网络设备也无须等待该HARQ进程对应的HARQ-ACK信息反馈，即可通过该HARQ进程继续向终端设备调度其他数据，使得网络设备无需等待，提高了终端设备和网络设备之间的数据传输效率。
或者，针对终端设备的上行HARQ进程，网络设备可以向终端设备配置或指示该上行HARQ进程对应的HARQ反馈功能状态。例如，将上行HARQ进程对应的HARQ反馈功能状态配置为非使能态。相应的，若终端设备确定该上行HARQ进程对应的HARQ反馈功能状态为非使能态，则终端设备被上行授权调度在该上行HARQ进程上发送TB后，无需等待网络设备的反馈针对该TB的反馈，即可根据网络设备的指示再次使用该上行HARQ进程传输另一TB，提高了终端设备和网络设备之间的数据传输效率。
在本申请中，终端设备的下行HARQ进程或上行HARQ进程对应的HARQ反馈功能状态可以为非使能态。例如，网络设备可以将终端设备的部分或全部HARQ进程对应的HARQ反馈功能状态配置为使能态或者非使能态。其中，非使能态也称为去使能态(disabled)。
可选地，对于下行HARQ进程，若一个HARQ进程对应的HARQ反馈功能状态为使能态，那么终端设备通过该HARQ进程接收到传输块TB后，需要向网络设备发送该TB对应的HARQ-ACK信息；或，终端设备需要收到网络设备对该TB的反馈才能再次使用该HARQ进程；或，终端设备需要根据调度该TB的DCI进行对应的HARQ-ACK信息反馈；或，终端设备根据调度通过该HARQ进程传输第一物理信道的DCI向网络设备发送该HARQ进程中传输的第一物理信道对应的HARQ-ACK信息。
可选地，对于下行HARQ进程，若一个HARQ进程对应的HARQ反馈功能状态为非使能态，那么终端设备通过该HARQ进程接收到TB后，不需要向网络设备发送该TB对应的HARQ-ACK信息；或，终端设备不需要收到网络设备对该TB的反馈就可以再次使用该HARQ进程；或，终 端设备不需要根据调度该TB的DCI进行对应的HARQ-ACK信息反馈；或，终端设备不根据调度通过该HARQ进程传输第一物理信道的DCI，向网络设备发送该HARQ进程中传输的第一物理信道对应的HARQ-ACK信息。
可选地，在本申请中，HARQ-ACK信息包括TB的译码结果对应的ACK信息或NACK信息。
可选地，对于上行HARQ进程，若一个HARQ进程对应的HARQ反馈功能状态为使能态，那么终端设备通过该HARQ进程发送传输块TB后，需要收到网络设备对该TB的反馈才能再次使用该HARQ进程(例如使用该HARQ进程发送新的TB或再次发送该TB)；或，终端设备等待网络设备对该HARQ进程中传输的第一物理信道的反馈。
可选地，对于上行HARQ进程，若一个HARQ进程对应的HARQ反馈功能状态为非使能态，则说明终端设备通过该HARQ进程发送TB后，不需要收到网络设备对该TB的反馈就可以再次使用该HARQ进程(例如使用该HARQ进程发送新的TB或再次发送该TB)；或，终端设备不等待网络设备对该HARQ进程中传输的第一物理信道的反馈。
可选地，同一个HARQ进程两次被使用之间的时间间隔大于或等于第一时间长度，和/或，同一个HARQ进程两次被使用之间的时间间隔可以小于第二时间长度。其中，第一时间长度是根据接收设备的译码时间确定的，第二时间长度是根据RTT确定的。其中，第一时间长度小于第二时间长度。
可选地，对于下行传输，反馈包括终端设备向网络设备发送HARQ-ACK信息。
可选地，对于上行传输，反馈包括网络设备向终端设备发送HARQ-ACK信息，或网络设备向终端设备发送上行授权DCI。
可选地，HARQ进程的类型可以包括第一类型或者第二类型。其中，第一类型的HARQ进程可以包括HARQ反馈功能状态为非使能态的HARQ进程，第二类型的HARQ进程可以包括HARQ反馈功能状态为使能态的HARQ进程。
可选地，针对下行过程：
第一类型的HARQ进程还可以称为反馈去使能(disabled)的HARQ进程，或者上行HARQ反馈去使能的HARQ进程。终端设备不对第一类型的HARQ进程进行反馈(还可以理解为终端设备不响应第一类型的HARQ进程的一次调度)。即，网络设备通过HARQ进程向终端设备发送TB之后，终端设备无需向网络设备发送该HARQ进程该次传输对应的反馈消息(ACK或者NACK)，网络设备即可通过该HARQ进程发送TB，例如通过该HARQ进程传输新的TB。其中，反馈消息可以包括HARQ-ACK信息，HARQ-ACK可以为ACK或者NACK。
下面，结合图3，对第一类型的HARQ进程进行说明。
图3为本申请实施例提供的对第一类型的HARQ进程进行处理的示意图。请参见图3，假设终端设备中包括多个HARQ进程，该多个HARQ进程中的HARQ进程7为第一类型的HARQ进程。网络设备通过HARQ进程7向终端设备发送PDSCH 0对应的下行数据，且NDI为0。由于HARQ进程7为第一类型的HARQ进程，因此，终端设备接收到HARQ进程7对应的下行数据之后，终端设备无需向网络设备发送HARQ进程7的反馈消息，网络设备也无需等待终端设备发送的HARQ进程7的反馈消息，即可通过HARQ进程7向终端设备发送其它数据。例如，网络设备可以通过HARQ进程7向终端设备发送PSDCH 1对应的下行数据，且将NDI翻转为1，其中，对NDI进行翻转说明通过该HARQ进程7传输的下行数据为新的下行数据包。在网络设备向终端设备发送PDSCH 1对应的下行数据之后，网络设备可以继续向终端设备发送PDSCH 2对应的新的下行数据包，且将NDI翻转为0。
第二类型的HARQ进程还可以称为反馈使能(enable)的HARQ进程，或者上行HARQ反馈使能的HARQ进程。终端设备对第二类型的HARQ进程进行反馈(还可以理解为终端设备响应第二类型的HARQ进程)。即，网络设备通过HARQ进程向终端设备发送TB之后，终端设备需要向网络设备发送该HARQ进程对应的HARQ反馈(ACK或者NACK)，网络设备接收到HARQ-ACK之后，网络设备才可以通过该HARQ进程发送其它TB。
可选地，针对上行过程：
第一类型的HARQ进程还可以可以称为反馈去使能(disabled)的HARQ进程，或者下行HARQ反馈去使能的HARQ进程。在终端设备通过第一类型的HARQ进程向网络设备发送上行数据之后的预设时长之内例如在RTT时长之内，若网络设备再次调度终端设备通过该HARQ进程进行上行数据传输时，则终端设备可以通过该HARQ进程进行上行数据传输。
第二类型的HARQ进程还可以称为反馈使能(ensble)的HARQ进程，或者下行HARQ反馈使能的HARQ进程。在终端设备通过第一类型的HARQ进程向网络设备发送上行数据之后的预设时长之内，若网络设备再次调度终端设备通过该HARQ进程进行上行数据传输时，则终端设备可以忽略对该HARQ进程的调度。或者说，终端设备在该预设时长内不期待网络设备对该HARQ进程进行再次调度。
在本申请中，网络设备可以将终端设备中的部分HARQ进程配置为第一类型或非使能态，网络设备还可以通过DCI指示终端设备中HARQ进程的类型。如前所述，在终端设备中的至少部分HARQ进程为第一类型时，可以提高了终端设备和网络设备之间的数据传输效率。
下面，通过具体实施例对本申请所示的技术方案进行详细说明。需要说明的是，下面几个实施例可以独立存在，也可以相互结合，对于相同或相似的内容，在不同的实施例中不再重复说明。

可选地，网络设备确定DCI，并通过DCI调度终端设备进行下行接收例如调度终端设备进行PDSCH接收，其中，该DCI中包括该下行传输对应的HARQ进程号的指示信息。
可选地，网络设备确定DCI，并通过DCI调度终端设备进行上行发送例如调度终端设备进行PUSCH发送，其中，该DCI中包括该上行传输对应的HARQ进程号的指示信息。
可选的，网络设备在确定DCI的时候，可以根据该DCI要调度的HARQ进程(DCI中包括的HARQ进程号指示的HARQ进程)的类型，确定该类型的HARQ进程对应的DCI。例如，网络设备确定DCI要调度的HARQ进程为非使能态的HARQ进程，因此网络设备根据该确定的HARQ进程的类型，可以确定DCI。该HARQ进程的类型可以为网络设备配置的。HARQ进程的类型可以为第一类型或者第二类型。
网络设备可以预先配置终端设备中的HARQ进程的类型，也可以不预先配置终端设备中的HARQ进程的类型。若网络设备预先配置HARQ进程的类型，则网络设备可以根据预先配置确定HARQ进程的类型。网络设备预先配置终端设备中的HARQ进程的类型之后，网络设备还可以向终端设备发送该配置，例如，网络设备可以通过RRC信令、媒介接入控制(medium access control，MAC)控制单元(control element，CE)或者DCI向终端设备发送该配置。当然，网络设备也可以不向终端设备发送该配置。若网络设备不预先配置HARQ进程的类型，则网络设备可以在向终端设备发送DCI时才确定该DCI对应的HARQ进程的类型。
可选地，网络设备或终端设备可以根据配置的HARQ进程的类型确定调度该类型的HARQ进程的DCI的第一信息。第一信息包括如下信息中的至少一种：DCI的长度；或，DCI对应的无线网络设备临时标识(radio network temporary identifier，RNTI)；或，DCI对应的搜索空间；或，DCI对应的聚合等级。

可选地，终端设备可以通过如下方式确定是否对DCI调度的HARQ进程进行反馈：终端设备根据DCI确定HARQ进程的类型，并根据HARQ进程的类型，确定是否根据该DCI对该DCI调度的HARQ进程进行反馈。
可选地，终端设备可以通过如下方式确定是否对DCI调度的HARQ进程进行反馈：终端设备可以根据DCI的第一信息，确定是否对DCI指示的HARQ进程进行反馈。可选的，第一信息包括如下信息中的至少一种：DCI的长度；或，DCI对应的RNTI；或，DCI对应的搜索空间；或，DCI对应的聚合等级。可选的，终端设备可以根据DCI的第一信息确定HARQ进程的类型，并根据HARQ进程的类型确定是否对HARQ进程进行反馈。
在上述实现方式中，HARQ进程的类型为第一类型或第二类型。若HARQ进程的类型为第一类型，则终端设备确定不对HARQ进程进行反馈；或者，若HARQ进程的类型为第二类型，则终端设备确定对HARQ进程进行反馈。
可选地，对于上行传输，终端设备根据该DCI确定该DCI调度的HARQ进程对应的HARQ反馈功能状态。可选地，终端设备可以根据DCI的第一信息，确定该DCI调度的HARQ进程对应的HARQ反馈功能状态。可选的，第一信息包括如下信息中的至少一种：DCI的长度；或，DCI对应的RNTI；或，DCI对应的搜索空间；或，DCI对应的聚合等级。可选的，终端设备可以根据DCI的第一信息确定HARQ进程的类型，并根据HARQ进程的类型确定HARQ进程对应的HARQ反馈功能状态。
需要说明的是，当第一信息不同时，终端设备根据第一信息确定的HARQ进程对应的HARQ反馈功能状态也不同，或者，当第一信息不同时，终端设备根据第一信息确定HARQ进程的类型的方式不同，在图5-图8所示的实施例中进行说明，此处不再进行赘述。
在一种可能的实施例中，终端设备可以根据DCI确定DCI指示的HARQ进程的类型，HARQ进程的类型为第一类型或者第二类型。终端设备确定得到HARQ进程的类型之后，可以根据HARQ进程的类型进行其它处理，本申请实施例对终端设备根据和HARQ进程进行的处理事项不做具体限定。
本申请实施例提供的数据传输方法，在终端设备根据DCI确定不对DCI指示的HARQ进程进行反馈时，则终端设备无需对该HARQ进程进行反馈，网络设备也无需等待终端设备的反馈即可通过该HARQ进程传输其它数据，提高了数据传输效率。进一步的，终端设备通过DCI即可确定得到是否需要对HARQ进程进行反馈，网络设备无需向终端设备发送额外的信令，节省了信令开销。
在上述任意一个实施例的基础上，下面，结合图5-图8所示的实施例，对终端设备根据不同的第一信息确定是否对HARQ进程进行反馈的过程进行说明。
图5为本申请实施例提供的另一种数据传输方法的流程示意图。在图5所示的实施例中，第一信息为DCI的长度。请参见图5，该方法可以包括：
S501、网络设备确定DCI的长度，并根据DCI的长度确定DCI。

可选地，当DCI的长度为第一DCI长度时，DCI不包括如下信息域中的至少一种：物理上行控制信道PUCCH的TPC命令、下行分配指示(downlink assignment index，DAI)、PUCCH资源指示、PDSCH 到HARQ反馈的定时指示、单次HARQ-ACK反馈请求、PDSCH分组指示、新反馈指示NFI、触发反馈组指示。
可选地，当DCI的长度为第二DCI长度时，DCI包括如下信息域中的至少一种：PUCCH的TPC命令、下行分配指示DAI、PUCCH资源指示、PDSCH到HARQ反馈的定时指示、单次HARQ-ACK反馈请求、PDSCH分组指示、新反馈指示NFI、触发反馈组指示。
当DCI调度不同类型的HARQ进程时，对应的DCI的长度不同，例如为第一DCI长度或第二DCI长度。其中，第一DCI长度的DCI中包括的信息域与第二DCI长度的DCI中包括的信息域至少部分不同。下面，以下行调度为例，结合表4-表6进行说明。
例如，当DCI格式为DCI格式1_0时，第一DCI长度和第二DCI长度对应的DCI中各DCI域(还可以称为信息域)的比特数如表4所示：
表4

请参见表6，若网络设备确定DCI的长度为第一DCI长度，则该DCI中如下四个DCI域(还可以称为信息域)的长度为0：下行链路分配索引、预定PUCCH的TPC命令、PUCCH资源指示、PDSCH-to-HARQ_反馈定时指示。换句话说，若网络设备确定DCI的长度为第一DCI长度，则该DCI中不包括如下四个信息域：下行链路分配索引、预定PUCCH的TPC命令、PUCCH资源指示、PDSCH-to-HARQ_反馈定时指示。
S502、网络设备向终端设备发送DCI。
S503、终端设备根据DCI的长度，确定该DCI调度的HARQ进程对应的HARQ反馈功能状态。
可选的，终端设备可以先确定DCI的长度，再根据DCI的长度确定是否对DCI指示的HARQ进程进行反馈。DCI的长度可以为第一DCI长度或第二DCI长度，若DCI的长度为第一DCI长度，则终端设备确定不对HARQ进程进行反馈；或，若DCI的长度为第二DCI长度，则终端设备确定对HARQ进程进行反馈。
终端设备可以通过不同的DCI长度进行DCI检测(还可以称为PDCCH检测)，将检测到DCI时所使用的DCI长度确定为该DCI的长度。例如，若终端设备根据第一DCI长度检测到该DCI，则可以确定DCI的长度为第一DCI长度；或者，若终端设备根据第二DCI长度检测到该DCI，则可以确定 DCI的长度为第二DCI长度。在终端设备进行PDCCH检测的过程，当DCI的长度为第一DCI长度时，DCI中包括的信息比特较少，使用相同的PDCCH传输资源时可以增加PDCCH检测的可靠性。
可选的，上述检测可以为盲检测。为了便于描述，在下文中，以该检测为盲检测为例进行说明。下文所涉及的盲检测还可以称为DCI盲检测或者PDCCH盲检测。
在实际应用过程中，若终端设备使用第一DCI长度和第二DCI长度进行盲检测，则可能会使得终端设备进行盲检测的次数较多。为了减少终端设备进行盲检测的次数，终端设备可以根据网络设备对其HARQ进程的配置，确定盲检测所使用的DCI长度。
例如，若终端设备中的HARQ进程均被配置为第一类型，终端设备进行PDCCH盲检测所使用的DCI长度包括第一DCI长度。在该种情况下，终端设备可以不使用第二DCI长度进行盲检测，使得终端设备进行盲检测的次数较少。
例如，若终端设备中的HARQ进程均被配置为第二类型，终端设备进行PDCCH盲检测所使用的DCI长度包括第二DCI长度。在该种情况下，终端设备可以不使用第一DCI长度进行盲检测，使得终端设备进行盲检测的次数较少。
例如，若终端设备中的部分HARQ进程被配置为第一类型，部分HARQ进程被配置为第二类型，终端设备进行PDCCH检测所使用的DCI长度包括第一DCI长度和第二DCI长度。
在实际应用过程中，终端设备除了接收用于调度数据传输的DCI之外，终端设备可能还接收其它类型的DCI，在终端设备接收其它类型的DCI时，终端设备可以通过其它DCI长度进行其它类型的DCI的盲检测。换句话说，终端设备进行盲检测所使用的DCI长度还可以为其它DCI长度(除第一DCI长度和第二DCI长度之外的DCI长度)。
在终端设备使用第一DCI长度和第二DCI长度进行PDCCH盲检测时，为了减少终端设备进行盲检测的次数，可以为不同的DCI长度配置不同的聚合等级。例如，配置第一DCI长度对应第一聚合等级，配置第二DCI长度对应第二聚合等级，第一聚合等级小于或等于第二聚合等级。由于第一DCI长度小于第二DCI长度，在保证相同PDCCH传输的可靠性的情况下，传输第一DCI长度对应的DCI需要的资源少于传输第二DCI长度对应的DCI所需的资源，从而减少终端设备的PDCCH盲检测次数。
为了减少DCI盲检测的虚警，在终端设备通过一种DCI长度检测到DCI之后，终端设备还可以进一步确定DCI对应的HARQ进程的类型与该DCI长度对应的HARQ进程的类型是否一致，若一致，再确定是否对HARQ进程进行反馈，若不一致，则终端设备丢弃DCI或者不接收DCI对应的PDSCH。
例如，若终端设备根据第一DCI长度检测到DCI，终端设备根据该第一DCI长度可以确定该DCI指示的HARQ进程的类型为第一类型。终端设备可以再根据其它方式进一步确认该HARQ进程的类型是否为第一类型。若终端设备根据其它方式确认该HARQ进程的类型也为第一类型，则终端设备可以确定不对该HARQ进程进行反馈，这样，可以减少DCI盲检测的虚警。若终端设备根据其它方式确定该HARQ进程的类型为第二类型，则终端设备可以忽略该DCI的调度，或者终端设备可以不接收该DCI调度的PDSCH。
例如，若终端设备根据第二DCI长度检测到DCI，终端设备根据该第二DCI长度可以确定该DCI指示的HARQ进程的类型为第二类型。终端设备可以再根据其它方式进一步确认该HARQ进程的类型是否为第二类型。若终端设备根据其它方式确认该HARQ进程的类型也为第二类型，则终端设备可以确定对该HARQ进程进行反馈，这样，可以减少DCI盲检测的虚警。若终端设备根据其它方式确定该HARQ进程的类型为第一类型，则终端设备可以忽略该DCI的调度，或者终端设备可以不接收该DCI调度的PDSCH。
在上述两个示例中，其它方式可以为：终端设备通过网络设备预先配置的HARQ进程的类型，确定HARQ进程的类型；或者，终端设备可以通过图6-图8实施例中的任意方式确定HARQ进程的类型。
在图5所示的实施例中，在终端设备根据DCI的长度即可确定是否对DCI指示的HARQ进程进行反馈。若终端设备确定不对DCI指示的HARQ进程进行反馈时，则终端设备无需对该HARQ进程进行反馈，网络设备也无需等待终端设备的反馈即可通过该HARQ进程传输其它数据，提高了数据传输效率。进一步的，通过DCI的长度即可隐式的指示出HARQ进程的类型，无需在DCI中增加额外的信令，节省了信令开销。

需要说明的是，若HARQ进程的类型为第一类型，则网络设备生成的DCI的长度可以为第一长度。 若HARQ进程的类型为第二类型，则网络设备生成的DCI的长度可以为第二长度。该过程可以参见S501，此处不再进行赘述。

可选的，上述检测可以为盲检测。为了便于描述，在下文中，以该检测为盲检测为例进行说明。
在实际应用过程中，若终端设备使用第一RNTI和第二RNTI进行盲检测，则可能会使得终端设备进行盲检测的次数较多。为了减少终端设备进行盲检测的次数，终端设备可以根据网络设备对其HARQ进程的配置，确定盲检测所使用的RNTI。

可选的，在网络设备调度终端设备通过第一HARQ进程进行上行传输时，终端设备可以先判断在当前时刻之前的预设时长之内，终端设备是否通过第一HARQ进程传输上行数据。若终端设备在当前时刻之前的预设时长之内未通过第一HARQ进程传输上行数据，则终端设备通过第一HARQ进程向网络设备发送上行数据。若终端设备在当前时刻之前的预设时长之内通过第一HARQ进程传输上行数据，则终端设备根据第一HARQ进程的类型确定是否通过第一HARQ进程向网络设备传输上行数据。可选的，若第一HARQ进程的类型为第一类型，则终端设备通过第一HARQ进程向网络设备传输上行数据；若第一HARQ进程的类型为第二类型，则终端设备可以忽略网络设备的调度，即，终端设备不通过第一HARQ进程向网络设备发送上行数据。
在上述过程中，当网络设备调度终端设备通过第一类型的HARQ进程传输上行数据时，网络设备可以连续的调度终端设备通过第一类型的HARQ进程传输上行数据，在终端设备通过第一类型的HARQ进程传输上行数据之后，终端设备无需等待预设时长，终端设备即可通过第一类型的HARQ进程再进行上行数据传输，提高了终端设备和网络设备之间的数据传输效率。
