具体实施方式
为了便于理解，首先，对本申请所涉及的概念进行说明。
终端设备：通常具有无线收发功能，终端设备可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述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、虚拟现实(virtual reality，简称VR)终端设备、增强现实(augmented reality，简称AR)终端设备、工业控制(industrial control)中的无线终端、车载终端设备、无人驾驶(selfdriving)中的无线终端、远程医疗(remote medical)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备、可穿戴终端设备等。本申请实施例所涉及的终端设备还可以称为终端、用户设备(user equipment，UE)、接入终端设备、车载终端、工业控制终端、UE单元、UE站、移动站、移动台、远方站、远程终端设备、移动设备、UE终端设备、无线通信设备、UE代理或UE装置等。终端设备也可以是固定的或者移动的。
网络设备：通常具有无线收发功能，网络设备可以具有移动特性，例如，网络设备可以为移动的设备。可选的，网络设备可以为通信卫星、气球站。例如，通信卫星可以按照轨道高度的不同分为低地球轨道(low earth orbit，LEO)卫星、中地球轨道(medium earth orbit，MEO)卫星、地球同步轨道(geostationary earth orbit，GEO)卫星、高椭圆轨道(High Elliptical Orbit，HEO)卫星等。例如，LEO卫星的轨道高度范围通常为500km～1500km，轨道周期(围绕地球旋转的周期)约为1.5小时～2小时。用户间单跳通信的信号传播延迟约为20ms，用户间单跳通信时延是指终端设备到网络设备之间的传输时延，或者网络设备到传输设备之间的时延。最大卫星可视时间约为20分钟，最大可视时间是指卫星的波束覆盖地面某一片区域的最长时间，LEO卫星相对地面是移动的，随着卫星的移动，其覆盖到的地面区域也是变化的。LEO卫星的信号传播距离短，链路损耗少，对终端设备的发射功率要求不高。GEO卫星的轨道高度通常为35786km，轨道周期为24小时。用户间单跳通信的信号传播延迟约为250ms。为了保证卫星的覆盖以及提升通信网络的系统容量，卫星可以采用多波束覆盖地面，例如，一颗卫星可以形成几十或者几百个波束来覆盖地面，一个波束可以覆盖直径几十至几百公里的地面区域。当然，网络设备还可以为设置在陆地、水域等位置的基站，例如，网络设备可以是下一代基站(next generation NodeB，gNB)或者下一代演进型基站(next generation-evolved NodeB，ng-eNB)。其中，gNB为UE提供新空口(new radio,NR)的用户面功能和控制面功能,ng-eNB为UE提供演进型通用陆地无线接入(evolved universal terrestrial radio access,E-UTRA)的用户面功能和控制面功能，需要说明的是，gNB和ng-eNB仅是一种名称，用于表示支持5G网络系统的基站，并不具有限制意义。网络设备还可以为GSM系统或CDMA系统中的基站(base transceiver station，BTS)，也可以是WCDMA系统中的基站(nodeB，NB)，还可以是LTE系统中的演进型基站(evolutional node B，eNB或eNodeB)。或者，网络设备还可以为中继站、接入点、车载设备、可穿戴设备以及5G之后的网络中的网络侧设备或未来演进的PLMN网络中的网络设备、路边站点单元(road site unit，RSU)等。
非地面通信往网络：非地面通信网络NTN技术一般采用卫星通信的方式向地面的终端设备提供通信服务。相比于地面蜂窝网通信，卫星通信具有很多独特的优点。首先，卫星通信不受地域的限制，例如一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而 不做通信覆盖的区域，而对于卫星通信来说，由于一颗卫星即可以覆盖较大的地面，加之卫星可以围绕地球做轨道运动，因此理论上地球上每一个角落都可以被卫星通信覆盖。其次，卫星通信有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到，从而使这些地区的用户享受到先进的语音通信和移动互联网技术，有利于缩小与发达地区的数字鸿沟，促进这些地区的发展。再次，卫星通信距离远，且通信距离增大通讯的成本没有明显增加；最后，卫星通信的稳定性高，不受自然灾害的限制。
为了保证卫星的覆盖以及提升整个卫星通信系统的系统容量，卫星采用多波束覆盖地面，一颗卫星可以形成几十甚至数百个波束来覆盖地面；一个卫星波束可以覆盖直径几十至上百公里的地面区域。
自动重传请求：自动重传请求(automatic repeat request，ARQ)是一种错误纠正协议，在接收方接收到来自发送方的数据之后，根据前向错误更正技术判断接收到的数据是否发生损坏，如果没有损坏，则向发送方反馈确认信息(acknowledgement，ACK)，其中ACK用于告知发送方数据已经正确接收，发送方在接收到ACK之后可以继续发送新的数据；如果数据损坏，则接收方丢弃该损坏的数据，并且向发送方反馈否认信息(non-acknowledgement，NACK)，发送方在接收到NACK之后，可以向接收方重新发送原来的数据。
混合自动重传请求：混合自动重传请求(hybrid automatic repeat request，HARQ)是一种将前向纠错编码(forward error correction，FEC)和ARQ相结合而形成的技术，在上述介绍的ARQ的基础上，将之前传输有误的数据缓存起来，与现有的损坏数据做分集合并，从而提高信息正确解码的概率，这种结合了分集合并和ARQ的技术就称为HARQ，HARA与ARQ的区别之处在于：1)HARQ中会将损坏的数据进行缓存，而ARQ中则将损坏的数据直接丢弃；2)HARQ中会将缓存数据与当前数据软合并解码，以提高正确检测率。
传输块：从媒质接入控制(medium access cntrol，MAC)层发往物理层的数据是以传输块(TransportBlock，TB)的形式组织的，其中一个TB对应包含一个MAC协议数据单元(protocol data unit，PDU)的数据块，这个数据块会在一个传输时间间隔(transmission time interval，TTI)内发送，同时也是HARQ重传的单位。
在对本申请所涉及的相关概念进行解释之后，下面结合图1-图2，对本申请中的通信系统的架构进行说明。
图1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1，包括终端设备101和卫星102，终端设备101和卫星102之间可以进行无线通信。终端设备101和卫星102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102具有基站的功能，终端设备101和卫星102之间可以直接通信。在系统架构下，可以将卫星102称为网络设备。
图2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2，包括终端设备201、卫星202和基站203，终端设备201和卫星202之间可以进行无线通信，卫星202与基站203之间可以通信。终端设备201、卫星202和基站203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202不具有基站的功能，终端设备201和基站203之间的通信需要通过卫星202的中转。在该种系统架构下，可以将基站203称为网络设备。
在上述实施例的基础上，下面对本申请所涉及的背景技术进行进一步的详细介绍：
首先对NR中的下行HARQ机制进行说明：
在NR中有两级重传机制，分别是媒质接入控制(medium access cntrol，MAC)层的HARQ机制和无线链路控制(radio link control，RLC)层的ARQ机制，MAC层的HARQ机制能够提供快速重传，RLC层的ARQ机制能够提供可靠的数据传输，在数据传输过程中，丢失或出错的数据的重传主要是由MAC层的HARQ机制处理的，并由RLC层的重传功能进行补充。
HARQ使用停等协议(Stop-and-Wait Protocol)来发送数据。在停等协议中，发送方发送一个TB后，就停下来等待确认信息ACK，这样一来，每次传输后发送方都会停下来等待ACK，则会导致用户吞吐量很低。
因此，NR中可以使用多个并行的HARQ进程，当一个HARQ进程在等待ACK时，发送方可以使用另一个HARQ进程来继续发送数据，这些HARQ进程共同组成了一个HARQ实体，这个实体结合了停等协议，允许数据连续传输。
在HARQ中有上行HARQ和下行HARQ之分，其中，上行HARQ针对上行数据传输，下行HARQ针对下行数据传输。两者相互独立。
基于目前NR协议的规定，终端设备对应每个服务小区都有各自的HARQ实体，每个HARQ实体维护一组并行的下行HARQ进程，目前每个下行载波最大支持16个HARQ进程。
在一种可能的实现方式中，网络设备可以根据网络部署情况，通过无线资源控制(Radio Resource Control，RRC)信令向终端设备半静态配置的指示最大的下行HARQ进程数；在另一种可能的实现方式中，如果网络设备没有提供相应的配置参数，则缺省的下行HARQ进程数可以为8。
其中，每个下行HARQ进程对应一个HARQ进程身份标识(identity document，ID)，广播控制信道(broadcast control channel，BCCH)使用一个专用的广播HARQ进程。
对于不支持下行空分复用的终端设备，每个下行HARQ进程只能同时处理1个TB；对于支 持下行空分复用的终端设备，每个下行HARQ进程可以同时处理1个或者2个TB。
HARQ在时域上分为同步和异步两类，在频域上分为非自适应和自适应两类，NR中下行所使用的是异步自适应HARQ机制，异步HARQ即重传可以发生在任意时刻，同一个TB的重传与上一次传输的时间间隔是不固定的，自适应HARQ即可以改变重传所使用的频域资源和调制编码方式(modulation and coding scheme，MCS)。
接着对NR中的下行数据传输进行介绍：
在网络设备在给终端设备传输下行数据之前，网络设备需要为给终端设备的下行传输分配合适的时频域资源，并通过承载调度信令的物理下行控制信道(physical downlink control channel，PDCCH)将分配的时频域资源告知终端设备，其中PDCCH例如可以包括：分配的时频域资源位置、MCS、使用的下行HARQ进程ID、初传重传指示等信息。
终端设备根据接收到的PDCCH，可以在对应的资源上使用指示的HARQ进程接收下行数据，下面结合图3-图5进行说明，图3为本申请实施例提供的数据块传输的示意图一，图4为本申请实施例提供的数据块传输的示意图二，图5为本申请实施例提供的数据块传输的示意图三。
在一种可能的实现方式中，终端设备接收下行数据的过程例如可以包括如下方式：
a)如果终端设备接收到数据的是初传数据，并且该初传数据对应的HARQ进程的缓存中当前没有其他数据，则终端设备将接收到的下行数据存入对应的HARQ进程的缓存中，并对该数据进行解码。
参见图3，网络设备例如可以为发送方，终端设备作为接收方，接收到的数据1是第一次接收到，也就是上述介绍的初传数据，则终端设备将数据1存入对应的HARQ进程的缓存中。
b)如果终端设备接收到的数据是初传数据，并且该初传数据对应的HARQ进程的缓存中已有其他数据，则终端设备采用本次接收的下行数据替换该HARQ进程的缓存中的已有数据，从而将本次接收的下行数据存入该HARQ进程的缓存中，并对该数据进行解码。
参见图4，网络设备例如可以为发送方，终端设备作为接收方，接收到的数据1是第一次接收到，也就是上述介绍的初传数据，以及当前HARQ进程的缓存中已有数据1，则终端设备可以采用本次接收的数据2替换该HARQ进程的缓存中的已有数据1，从而将本次接收的数据2存入该HARQ进程的缓存中.
c)如果终端设备接收到的是重传数据，则终端设备将本次接收的下行数据与对应HARQ进程的缓存中的已有数据进行软合并，并对合并后的数据进行解码。
参见图5，网络设备例如可以为发送方，终端设备作为接收方，假设终端设备第二次接收到的数据3是重传数据，也就是说当前数据3并非第一次传输，而是重复传输的数据，从图3可以看出，两次接收到的数据3均不完整，则终端设备可以将本次接收到的不完整的数据3与对应HARQ进程的缓存中的已有的不完整的数据3进行软合并，假设恰好可以得到完整的数据3，则此时终端设备对合并后的数据进行解码，就可以得到ACK的解码结果。
在一种可能的实现方式中，终端设备如果解码成功，则向网络设备发送ACK反馈，网络设备在收到ACK后，就可以使用该HARQ进程继续调度新传数据，例如参加图4，网络设备接收到针对数据1的ACK，则可以使用该HARQ进程继续调度新传数据2。
在另一种可能的实现方式中，终端设备如果解码失败，则向网络设备发送NACK反馈，网络设备在收到NACK后，由网络设备决定是使用该HARQ继续调度该数据块的重传还是放弃该数据块调度新传数据，例如参加图5，网络设备接收到针对数据3的NACK，则可以使用该HARQ进程继续调度该数据块3的重传。
在网络设备收到来自终端设备的针对某个HARQ进程的ACK/NACK反馈之前，不能使用该HARQ进程进行数据传输。
为了增强覆盖，NR还支持下行捆绑(bundling)传输，也就是说对于同一个下行TB，网络设备在相同的频域资源上连续地重复发送多次，终端设备在完成一个bundling的接收后，对接收到的数据一并进行解码，其中，下行bundling包含的重复传输次数可以由网络RRC配置。
值得说明的是，上述介绍的NR中的下行HARQ机制和下行数据传输，其可以很好的适用于传统的陆地NR系统，然而与传统陆地NR系统采用的蜂窝网络相比，NTN中终端设备与卫星之间的信号传播时延大幅增加，如果在NTN系统中直接沿用目前陆地NR系统的下行HARQ机制，则目前NR协议所支持的最大HARQ进程数目16，不足以支持NTN中下行数据的连续传输。另一方面，如果增大下行HARQ进程数目，无疑会增加终端设备的处理复杂度。
基于此，为了在不增加HARQ进程数目的情况下保证数据传输连续性，目前NTN标准化过程中已同意引入开启/关闭HARQ的方案，并形成了以下明确的结论：
1、网络设备可以配置是否开启HARQ功能。
2、如果HARQ功能关闭，则终端设备不需要向网络设备发送针对物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的HARQ反馈。
3、在关闭HARQ反馈的情况下，为了保证数据传输可靠性，仍然支持HARQ重传。
4、可以基于终端设备、或者基于HARQ进程、或者基于PDCCH进行HARQ功能开启或关闭的配置。
其中，对于基于终端设备进行配置的方式，即配置终端设备的所有HARQ进程的HARQ功能 同时处于开启或关闭状态；
对于基于HARQ进程进行的配置方式，即对于一个终端设备的多个HARQ进程，可以配置其中一部分HARQ进程的HARQ功能为开启状态，另一个部分HARQ进程的HARQ功能为关闭状态。
对于基于PDCCH进行的配置方式，即通过PDCCH指示本次传输使用的HARQ进程的HARQ反馈功能为开启状态或者关闭状态。
基于上述结论，对于关闭HARQ反馈功能的下行传输，网络设备可以配置重复(repetition)传输或者盲调度重传，通过增加重传次数来提升数据传输可靠性。
但由于网络设备不能获得终端设备的ACK/NACK反馈，因此网络设备并不知道终端设备下行接收的实际情况，如果网络设备选择的MCS过高或者重传次数过少，则可能导致终端设备下行接收失败；如果网络设备选择的MCS过低或者重传次数过多，则会影响数据传输效率。
基于上述介绍的内容可以确定的是，目前现有技术的方案中，因为HARQ反馈功能的关闭，网络设备的调度策略可能无法匹配终端设备的真实信道环境，从而会对通信质量造成影响。
针对现有技术中的问题，本申请提出了如下技术构思：终端设备针对关闭HARQ反馈的下行传输的解码结果进行统计，并向网络设备上报该统计结果，从而可以辅助网络设备调整调度参数，例如调整MCS等级、重传次数等，以使得网络设备的调度策略能更好地匹配终端设备的真实信道环境，提升调度性能和通信质量。
下面结合具体的实施例对本申请提供的通信方法进行详细介绍，首先结合图6进行说明，图6为本申请其中一实施例提供的通信方法的流程图。
如图6所示，该方法包括：
S601、终端设备获取网络设备的配置信息。
在本实施例中，配置信息可以用于确定统计信息，或者配置信息还可以用于向网络设备发送统计信息，其中，终端设备获取配置信息的实现方式例如可以为：终端设备作为接收方，获取接收来自于网络设备的配置信息；或者，终端设备还可以预先存储网络设备的配置信息，从而从本地获取网络设备的配置信息。
在一种可能的实现方式中，配置信息可以包括向网络设备发送统计信息的条件，例如可以设置针对某些值的次数门限，当这些值满足次数门限时，从而可以向网络设备发送统计信息；或者，配置信息可以包括向网络设备发送统计信息的周期，或者配置信息还可以包括向网络设备发送统计信息的时域资源、频域资源等，本实施例对配置信息的具体实现方式不做特别限制，凡是用于指示终端设备向网络设备发送统计信息的，均可以作为本实施例中的配置信息。
在另一种可能的实现方式中，配置信息还例如可以包括至少一个计数器，其中，各个计数器用于实现确定统计信息。
或者，在可能的实现方式中，配置信息还可以包括额外的指示信息，例如可以包括统计信息的发送次数等，本实施例对此不做限定。
S602、终端设备根据配置信息确定统计信息，其中，统计信息用于统计针对下行传输的解码结果。
在本实施例中，统计信息是用于统计针对下行传输的解码结果的，结合上述介绍的内容，本领域技术人员可以确定的是，终端设备针对下行传输进行解码，当解码成功时，更新解码结果ACK的次数，当解码失败时，更新解码结果为NACK的次数。
则在一种可能的实现方式中，统计信息包括如下中的至少一种：初传解码对应的HARQ结果为ACK的次数、初传解码对应的HARQ结果为NACK的次数、最后一次传输的解码对应的HARQ结果为NACK的次数、初传解码的次数。
其中，最后一次传输是指在此次传输结束之后，就传输其余的第二数据块，不传输此次传输的第一数据块了。
具体的，若某一个数据重复传输多次，则最后一次传输的解码对应的HARQ结果为NACK也就是最后一次重传的解码对应的HARQ结果为NACK；若某一个数据仅传输一次，则最后一次传输的解码对应的HARQ结果为NACK也就是初传的解码对应的HARQ结果为NACK。
可以理解的是，初传解码结果为ACK的次数和初传解码结果为NACK的次数之和，即为初传解码的次数。
在本实施例中，确定统计信息的一种可能的实现方式可以为，终端设备接收至少一个PDSCH，其中，各PDSCH对应的HARQ进程关闭了HARQ反馈功能，此时终端设备在接收到数据之后，不会向网络设备发送HARQ反馈。
则终端设备可以对至少一个PDSCH进行解码，得到解码结果，解码结果可以为ACK或者NACK，接着终端设备根据解码结果更新配置信息，从而确定统计信息。
其中，配置信息例如可以包括第一计数器(inital_ACK_count)、第二计数器(inital_NACK_count)和第三计数器(residual_NACK_count)，其中，第一计数器用于指示初传解码结果为ACK的次数，第二计数器用于指示初传解码结果为NACK的次数，第三计数器用于指示最后一次传输的解码结果为NACK的次数。
则根据解码结果更新配置信息的一种可能的实现方式可以为：根据解码结果更新计数器，从 而确定统计信息。
例如上述介绍的各PDSCH为初传，则针对任一个PDSCH，PDSCH解码成功，则将第一计数器加1；
针对任一个PDSCH，PDSCH解码失败，则将第二计数器加1；
针对任一个PDSCH，与PDSCH的HARQ进程相同的前一次PDSCH的解码失败，则将第三计数器加1。
其中，若PDSCH为初传，并且与PDSCH的HARQ进程相同的前一次PDSCH的解码失败，无论前一次PDSCH是重传还是初传，其均表明前一次的PDSCH解码失败了，也就是说终端设备针对该HARQ进程的上一个TB解码失败，则将用于表示最后一次传输的解码结果为NACK的次数的第三计数器加1。
通过采用计数器对解码结果进行统计，能够有序高效的实现对解码结果的统计，从而提升统计结果的处理效率。
或者，在另一种可能的实现方式中，也可以不采用计数器，而是直接对解码结果进行统计，从而得到统计信息，
以及在本实施例中，在终端设备发送统计信息之后，还可以初始化第一计数器、第二计数器和第三计数器，其中初始化例如可以将计数器置为0，或者是置为其余的初始化数值，本实施例对此不做限定，以为下一次统计信息做好准备，保证统计信息的正确性。
S603、终端设备发送统计信息。
在一种可能的实现方式，终端设备例如可以根据配置信息，通过上行链路中的资源向网络设备发送统计信息，其中配置信息例如可以为次数门限值，则可以在次数达到对应的次数门限值时，通过PUCCH发送统计信息，或者还可以通过PUSCH发送统计信息。
或者，终端设备例如还可以根据配置信息，通过辅链路中的资源向其余的终端设备发送统计信息，本实施例对终端设备发送统计信息的实现方式不做限制。
本申请实施例提供的通信方法，包括：终端设备获取网络设备的配置信息。终端设备根据配置信息确定统计信息，其中，统计信息用于统计针对下行传输的解码结果。终端设备发送统计信息。通过根据配置信息确定针对下行传输的解码结果的统计信息，并发送统计信息，以使得在HARQ进程关闭了HARQ反馈功能的情况下，网络设备仍然可以确定终端设备的真实信道环境，从而提升调度性能，以提升通信质量。
在上述实施例的基础上，本申请实施例提供的通信方法，在终端设备发送统计信息时，可以根据配置信息发送统计信息，其可以存在以下几种可能的实现方式：
在一种可能的实现方式中，可以采用终端设备触发上报的方式，也就是说当终端设备记录的ACK次数/NACK次数和/或误码率(BLER)达到网络设备配置的计数次数门限时，终端设备发送针对下行传输解码结果的统计信息。
在另一种可能的实现方式中，可以采用周期性上报的方式，也就是说终端设备基于网络设备的配置，周期性地发送针对下行传输解码结果的统计信息。
在又一种可能的实现方式中，可以采用网络设备触发上报的方式，也就是说终端设备基于网络设备的上报请求，向网络设备上报针对下行传输解码结果的统计信息。
下面结合具体的实施例和附图对这几种实现方式进行详细介绍：
首先结合图7-图11对终端设备触发上报的实现方式进行介绍，图7为本申请实施例提供的终端设备触发上报统计信息的示意图一，图8为本申请实施例提供的终端设备触发上报统计信息的示意图二，图9为本申请实施例提供的终端设备触发上报统计信息的示意图三，图10为本申请实施例提供的终端设备触发上报统计信息的示意图四，图11为本申请实施例提供的终端设备触发上报统计信息的示意图五。
在终端设备触发上报的一种可能的实现方式中，配置信息可以包括第一次数门限，其中，第一次数门限为针对下行初传解码结果为ACK的次数的门限。
则终端设备发送统计信息，可以包括：
若第一计数器大于或等于第一次数门限，则终端设备发送统计信息。
参见图7，假设在初始化各个计数器之后，终端设备对接收到的PDSCH进行解码依次得到了7个ACK、1个NACK和2个ACK，以及假设这些PDSCH均为初传，本实施例中第一计数器用于指示初传解码结果为ACK的次数，则根据上述依次得到的解码结果，可以确定第一计数器为9，以及假设配置信息中指示第一次数门限为9，此时第一计数器等于第一次数门限，则终端设备向网络设备发送统计信息，参见图7，终端设备可以通过PUSCH或者PUCCH向网络设备发送统计信息。
同时，终端设备初始化计数器，并持续对计数器进行更新，并与第一次数门限进行比较，以在第一计数器大于或等于第一次数门限时，再次向网络设备发送统计信息。
在终端设备触发上报的另一种可能的实现方式中，配置信息可以包括第二次数门限，其中，第二次数门限为针对下行初传解码结果为NACK的次数的门限。

若第二计数器大于或等于第二次数门限，则终端设备发送统计信息。
参见图8，假设在初始化各个计数器之后，终端设备对接收到的PDSCH进行解码依次得到了3个ACK和2个NACK，以及假设这些PDSCH均为初传，本实施例中第二计数器用于指示初传解码结果为NACK的次数，则根据上述依次得到的解码结果，可以确定第二计数器为2，以及假设配置信息中指示第二次数门限为2，此时第二计数器等于第二次数门限，则终端设备向网络设备发送统计信息，参见图8，终端设备可以通过PUSCH或者PUCCH向网络设备发送统计信息。
同时，终端设备初始化计数器，并持续对计数器进行更新，并与第二次数门限进行比较，以在第二计数器大于或等于第二次数门限时，再次向网络设备发送统计信息。
在终端设备触发上报的又一种可能的实现方式中，配置信息可以包括第三次数门限，其中，第三次数门限为针对最后一次传输的解码结果为NACK的次数的门限。
则终端设备发送统计信息，可以包括：
若第三计数器大于或等于第三次数门限，则终端设备发送统计信息。
参见图9，假设在初始化各个计数器之后，终端设备对接收到的PDSCH进行解码依次得到了4个NACK、1个ACK和1个NACK，其中，前4个NACK例如为数据1的4次重复传输的解码结果，可以看出数据1最后一次传输的解码结果为NACK，以及假设最后一个NACK为数据2的一次传输的解码结果，则可以看出数据2的最后一次传输的解码结果为NACK，本实施例中第三计数器用于指示最后一次传输的解码结果为NACK的次数，则根据上述依次得到的解码结果，可以确定第三计数器为2，以及假设配置信息中指示第三次数门限为2，此时第三计数器等于第三次数门限，则终端设备向网络设备发送统计信息，参见图9，终端设备可以通过PUSCH或者PUCCH向网络设备发送统计信息。
同时，终端设备初始化计数器，并持续对计数器进行更新，并与第三次数门限进行比较，以在第三计数器大于或等于第三次数门限时，再次向网络设备发送统计信息。
在终端设备触发上报的再一种可能的实现方式中，配置信息可以包括第四次数门限，其中，第四次数门限为针对下行初传解码次数的门限。
则终端设备发送统计信息，可以包括：

参见图10，假设在初始化各个计数器之后，终端设备对接收到的PDSCH进行解码依次得到了3个ACK、2个NACK和5个NACK，以及假设这些PDSCH均为初传，本实施例中第一计数器用于指示初传解码结果为ACK的次数，第二计数器用于指示初传解码结果为NACK的次数，则第一计数器和第二计数器之和就是初传解码的次数，则根据上述依次得到的解码结果，可以确定第一计数器和第二计数器之和为10，以及假设配置信息中指示第四次数门限为10，此时第一计数器和第二计数器之和等于第四次数门限，则终端设备向网络设备发送统计信息，参见图10，终端设备可以通过物理上行共享信道(physical uplink shared channel，PUSCH)或者物理上行控制信道(physical downlink control channel，PUCCH)向网络设备发送统计信息。
以及，之后终端设备对接收到的PDSCH继续进行解码，依次得到了2个ACK、1个NACK和7个NACK，则可以确定第一计数器和第二计数器之和为10，此时第一计数器和第二计数器之和等于第四次数门限，则终端设备可以继续向网络设备发送统计信息。
同时，终端设备初始化计数器，并持续对计数器进行更新，并与第四次数门限进行比较，以在第一计数器和第二计数器之和大于或等于第四次数门限时，再次向网络设备发送统计信息。
上述介绍的是单独根据第一次数门限、或者第二次数门限、或者第三次数门限、或者第四次数门限，向网络设备发送统计信息的实现方式，在本实施例中，各个次数门限之间还可以相互结合，以确定终端设备向网络设备发送统计信息。
以第一次数门限和第二次数门限为例，终端设备例如可以根据第一次数门限和第二次数门限，在第一计数器大于或等于第一次数门限，或者，在第二计数器大于或等于第二次数门限时，发送统计信息，则配置信息同时包括第一次数门限和第二次数门限。
参见图11，假设在初始化各个计数器之后，终端设备对接收到的PDSCH进行解码依次得到了3个ACK、2个NACK，以及假设这些PDSCH均为初传，则可以确定第二计数器为2，以及假设配置信息中指示第二次数门限为2，此时第二计数器等于第二次数门限，则终端设备向网络设备发送统计信息，参见图10，终端设备可以通过PUSCH或者PUCCH向网络设备发送统计信息。
以及，之后终端设备对接收到的PDSCH继续进行解码，依次得到了7个ACK、1个NACK和2个NACK，则可以确定第一计数器为9，此时第一计数器等于第一次数门限，则终端设备可以继续向网络设备发送统计信息。
同时，终端设备初始化计数器，并持续对计数器进行更新，并与第一次数门限和第一次数门限进行比较，以在第一计数器或第二计数器满足门限值时，再次向网络设备发送统计信息。
或者，终端设备还例如可以根据第一次数门限和第二次数门限，在第一计数器大于或等于第一次数门限，并且，在第二计数器大于或等于第二次数门限时，发送统计信息，则配置信息同时包括第一次数门限和第二次数门限。
其实现方式与上述介绍类似，只是第一计数器满足门限值和第二计数器满足门限值之间是“和”的关系，此处不再赘述。
本领域技术人员可以理解的是，上述介绍的第一次数门限、第二次数门限、第三次数门限和 第四次数门限的实现方式中，各个次数门限可以单独实现本实施例的方案，或者还可以互相结合以实现本实施例的方案，其中，互相结合的实现方式中，各个次数门限的限定条件之间可以是“和”的关系，还可以是“或”的关系，本实施例对此不做限定，对其详细的实现方式也不再赘述，具体的实现方式可以参照上述实施例中的实现方式得到。
在上述介绍的终端设备触发上报的实现方式的基础上，本实施例还可以在终端触发上报的实现方式中，增加第一定时器的限定，其中，第一定时器用于指示更新计数器的最长时间间隔。
下面结合图12-图10对增加第一定时器的限定的情况下，终端设备触发上报的实现方式进行介绍，图12为本申请实施例提供的结合第一定时器上报统计信息的示意图一，图13为本申请实施例提供的结合第一定时器上报统计信息的示意图二。
在本实施例中，配置信息在上述介绍的各个次数门限的基础上，还包括第一定时器的时长信息，第一定时器用于限定更新计数器的最长时间间隔，在终端设备接收PDSCH之后，终端设备可以启动第一定时器或者重启第一定时器，可以理解的是，终端设备接收到PDSCH之后，就会对计数器进行更新，因此可以启动或者重启第一定时器。
以及在本实施例中，若第一定时器超时，则表明在第一定时器的时间范围内，各个计数器没有发生更新，因为第一定时器是用于限制更新计数器的最长时间间隔的，因此可以重置第一计数器、第二计数器和第三计数器，例如可以重置为0，或者任意预设的数值，
通过设置第一定时器对计数器进行重置，能够保证发送的统计信息的实时性，从而能够使得根据统计信息确定终端设备的真实信道环境的准确性和及时性。
下面结合图12以第四次数门限为例，对第一定时器进行介绍，参见图12，假设配置信息包括第一定时器T1，在初始化各个计数器之后，终端设备对接收到的PDSCH进行解码依次得到了若干个ACK和NACK，参见图12可以确定的是，终端设备每接收到一次PDSCH，均会启动或者重启T1。
参见图12中的第4个PDSCH，在接收到该PDSCH之后，在一段时间内没有接收到PDSCH，没有接收到PDSCH，则第一定时器T1就不会启动或者重启，从而导致第一定时器T1超时，此时重置第一计数器、第二计数器和第三计数器。
在重置计数器之后接收到了一个PDSCH，则此时启动第一定时器T1，之后又一段时间没有接收到PDSCH，导致第一定时器T1超时，则再次重置第一计数器、第二计数器和第三计数器。
之后，终端设备接收到5个PDSCH，其解码结果依次为1个ACK、1个NACK和3个ACK，可以确定第一计数器和第二计数器之和为5，以及假设配置信息中指示第四计数门限为5，此时第一计数器和第二计数器之和等于第四次数门限，则终端设备发送统计信息，参见图12，终端设备例如可以通过PUSCH或者PUCCH向网络设备发送统计信息，在本实施例中，发送统计信息之后，还可以停止第一定时器。
同时，终端设备初始化计数器，并持续对计数器进行更新，并与第四次数门限进行比较，以在第一计数器和第二计数器之和大于或等于第四次数门限时，再次向网络设备发送统计信息。
下面结合再图13以第一次数门限和第二次数门限为例，对第一定时器进行介绍，图13中第一定时器超时的两次实现过程与图12中的相同，此处不再赘述。
在第一定时器第二次超时之后，终端设备接收到5个PDSCH，其解码结果依次为1个ACK、1个NACK和3个ACK，可以确定第一计数器为4，第二计数器为1，以及假设配置信息中指示第一次数门限为4，以及第二次数门限为2，此时第一计数器和等于第一数门限，则终端设备发送统计信息，参见图13，终端设备可以通过PUSCH或者PUCCH向网络设备发送统计信息。
同时，终端设备初始化计数器，并持续对计数器进行更新。
可以理解的是，图12和图13的实现方式是以次数门限值的两种可能的实现方式为例，对第一定时器进行了介绍，在实际实现过程，第一定时器可以应用于任一种次数门限值的情况下，其实现方式可以参照上述的介绍进行相应的扩展，此处不再赘述。
在上述实施例介绍的终端设备触发上报的实现方式的基础上，本实施例还可以在终端触发上报的实现方式中，结合误码率触发终端设备发送统计信息。
其中，当终端设备的ACK/NACK的次数已经满足配置信息所指示的次数门限的同时(可以是以上的任一种实现方式)，还可以统计误块率(block error rate，BLER)是否满足配置信息指示的BLER门限，若满足，则触发终端设备上报统计信息，对于BLER门限的配置和实现方式，可以包括以下几种实现方式：
在一种可能的实现方式中，配置信息可以包括第一误块率门限和第二误块率门限，其中，第一误块率门限和第二误块率门限用于限定初传误块率的统计结果，并且第一误块率门限大于第二误块率门限。
在本实施例中，终端设备可以获取初传误块率，其中，初传误块率是指针对初传解码结果为NACK的次数在针对初传解码的总次数所占的比例，若初传误块率大于或等于第一误块率门限，则终端设备向网络设备发送统计信息；或者，若初传误块率小于或等于第二误块率门限，则终端设备向网络设备发送统计信息。
在另一种可能的实现方式中，配置信息可以包括第三误块率门限和第四块率门限，其中，第三误块率门限和第四误块率门限用于限定残留误块率的统计结果，并且第三误块率门限大于第四 误块率门限。
在本实施例中，终端设备可以获取残留误块率，其中，残留误块率是指经过重传后解码结果仍为NACK的数据块个数在所有初传的数据块个数中所占的比例；若残留误块率大于或等于第三误块率门限，则终端设备发送统计信息；或者，若残留误块率小于或等于第四误块率门限，则终端设备发送统计信息。
在再一种可能的实现方式中，配置信息可以同时包括第一误块率门限、第二误块率门限、第三误块率门限和第四块率门限，其中，第一误块率门限大于第二误块率门限，第三误块率门限大于第四误块率门限。
在本实施例中，终端设备可以获取初始误块率和/或残留误块率，若初传误块率大于或等于第一误块率门限，则终端设备发送统计信息；或者，若初传误块率小于或等于第二误块率门限，则终端设备发送统计信息；或者，若残留误块率大于或等于第三误块率门限，则终端设备发送统计信息；或者，若残留误块率小于或等于第四误块率门限，则终端设备发送统计信息。
也就是说，当初始误块率和残留误块率满足任意一个误块率门限时，终端设备均发送统计信息。
上述介绍的是在终端设备的ACK/NACK的次数已经满足配置信息所指示的次数门限的同时，根据误块率和误块率门限，触发终端设备发送统计信息，在另一种可能的实现方式中，还可以单独根据误块率和误块率门限，触发终端设备发送统计信息，其实现方式与上述介绍的类似，只是不再考虑终端设备的ACK/NACK的次数。
通过增加误块率和误块率门限的实现方式，能够有效提升发送统计信息的灵活性。
在上述实施例的基础上，下面对周期性上报的实现方式进行介绍，结合图14进行介绍，图14为本申请实施例提供的周期性上报统计信息的示意图。
在周期性上报的一种可能的实现方式中，配置信息可以包括时域资源配置和频域资源配置，其中，时域资源配置包括第一周期和时间偏移信息，时间偏移信息是指在一个周期内的上报时间偏移，频域资源配置包括发送统计信息的PUCCH资源或者PUSCH资源。
则终端设备根据配置信息向网络设备发送统计信息，可以包括：
终端设备在第一周期结束时，通过频域资源配置指示的PUCCH资源或者PUSCH资源发送统计信息。
参见图14，假设在初始化各个计数器之后，终端设备对接收到的PDSCH进行解码，得到了若干个ACK和若干个NACK，在本实施例中，配置信息指示了第一周期，则每在第一周期结束时，终端设备就发送统计信息，以及本实施例中的配置信息还包括PUCCH资源或者PUSCH资源，则参见图7，终端设备可以通过配置信息指示的PUSCH或者PUCCH发送统计信息。
在上述实施例的基础上，下面对网络设备触发上报的实现方式进行介绍，结合图15进行介绍，图15为本申请实施例提供的网络设备触发上报统计信息的示意图。
在网络设备触发上报的一种可能的实现方式中，配置信息可以包括上报请求，其中，上报请求用于请求终端设备发送统计信息。
则终端设备根据配置信息向网络设备发送统计信息，可以包括：
终端设备在接收到上报请求时，通过网络设备配置的资源发送统计信息。
参见图15，假设在初始化各个计数器之后，终端设备对接收到的PDSCH进行解码，得到了若干个ACK和若干个NACK，在本实施例中，配置信息包括上报请求，参见图15，终端设备可以接收来自于网络设备的上报请求，在接收到上报请求时，终端设备可以通过网络设备配置的资源发送统计信息，参见图7，终端设备可以通过PUSCH或者PUCCH向网络设备发送统计信息。
在上述实施例的基础上，终端设备发送统计信息的一种可能的实现方式可以为：终端设备分别发送初传解码结果为ACK的次数、初传解码结果为NACK的次数、以及最后一次传输的解码结果为NACK的次数。
也就是说将三个参数分别进行发送。
或者，终端设备发送统计信息的另一种可能的实现方式可以为：终端设备分别发送第一比值和第二比值，其中，第一比值为初传解码结果为NACK的次数和初传解码的次数的比值，第二比值为最后一次传输的解码结果为NACK的次数和初传解码的次数的比值。
也就是说将各个参数通过比值的方式进行发送。
参照上述实施例的介绍，可以确定的是，终端设备可以通过PUCCH向网络设备发送统计信息，其中例如可以与信道状态信息(channel state information，CSI)一起上报统计信息，或者使用网络设备专门配置的上报资源上报统计信息。
以及，终端设备还可以通过PUSCH向网络设备发送统计信息，其中例如可以与MAC控制元素(Control Element，CE)一起上报统计信息。
综上所述，本实施例提供的通信方法，通过终端设备根据配置信息向网络设备发送统计信息，从而可以辅助网络设备调整MCS等级，以使得初传BLER更接近于目标BLER，并且还可以辅助网络设备调整重传次数，使经历MAC重传后的残余BLER更能匹配业务的传输可靠性要求，提升通信质量。
在上述实施例的基础上，网络设备可以向终端设备侧发送配置信息，从而根据配置信息接收 来自于终端设备的统计信息，下面结合图16对网络设备侧的通信方法进行介绍。
图16为本申请其中另一实施例提供的通信方法的流程图。
如图16所示，该方法包括：
S1601、网络设备向终端设备发送配置信息，其中，配置信息用于确定统计信息，统计信息用于统计针对下行传输的解码结果。
S1602、网络设备接收来自于终端设备的统计信息。
其中，配置信息和统计信息与上述实施例介绍的相同，此处对根据配置信息接收来自于终端设备的统计信息的实现方式不再赘述，具体的实现方式可以参照上述实施例中的内容。
本申请实施例提供的通信方法，包括：网络设备向终端设备发送配置信息，其中，配置信息用于确定统计信息，统计信息用于统计针对下行传输的解码结果。网络设备接收来自于终端设备的统计信息。通过根据配置信息接收来自于终端设备的统计信息，以使得在HARQ进程关闭了HARQ反馈功能的情况下，网络设备仍然可以确定终端设备的真实信道环境，从而提升调度性能，以提升通信质量。
