网络设备和终端设备可以部署在陆地上，包括室内或室外、手持或车载；可以部署在水面上；或者，可以部署在空中的飞机、气球或人造卫星上。本申请的实施例对网络设备和终端设备的应用场景不做限定。
通信系统中，终端设备可以接入网络设备，并和网络设备进行通信。示例性地，一个网络设备可以管理一个或多个(例如3个或6个等)小区，终端设备可以在该一个或多个小区中的至少一个小区中接入网络设备，并在该终端设备所在的小区中和网络设备进行通信。在本申请实施例中，至少一个可以是1个、2个、3个或者更多个，本申请实施例不做限制。
在如图1所示的移动通信系统中，终端设备可以通过上行传输资源向网络设备传输数据，以实现终端设备与网络设备之间的上行通信。在传输数据之前，终端设备需要通过上行授权获取上行传输资源，以通过该上行传输资源传输数据，上行授权包括：配置授权(configured grant，CG)和动态授权(dynamic grant，DG)。动态授权是指终端设备每次传输数据之前，均需要向网络设备请求分配上行传输资源，网络设备动态为终端设备分配本次传输所需的上行传输资源，通过动态授权获取的资源可以称为动态授权资源；而配置授权是指网络设备预先将分配的上行传输资源发送给终端设备，终端设备要发送上行数据时，从预先分配的上行传输资源中选择本次传输的上行传输资源即可，不需要向网络设备请求上行传输资源，通过配置授权获取到的资源可以称为配置授权资源。
网络设备和终端设备之间可以通过授权频谱进行通信，可以通过非授权频谱
(unlicensed spectrum)进行通信。对于非授权频谱，由于是共享的频谱资源，从而其存在很多不同空口技术，例如，Wi-Fi，长期演进(long term evolution，LTE)授权频谱辅助接入(License Assisted Access，LAA)等。为了保证不同空口技术在非授权频谱上共存，需要通过先听后说(listen before talk，LBT)机制避免冲突。LBT可以理解的是一个信道接入过程，终端设备在进行数据传输之前需要进行信道接入过程，如果信道接入过程通过，则可以进行数据传输；如果信道接入过程未通过，则不可以进行数据传输。
上述信道接入过程可以包括两类：第一类是基于固定时长的能量检测，终端设备可以检测非授权频谱上的信号强度，如果信号强度大于预设门限，则认为信道非空闲，否则就认为信道空闲。第二类是基于回退机制的能量检测，终端设备从预设窗口中随机选取数值A，在检测到至少A个空闲的能量检测的时隙之后，认为信道空闲，否则，认为信道忙碌。
当终端设备在非授权频谱上与网络设备进行数据传输时，终端设备可以通过自动重传方法避免配置授权丢包，主要步骤可以包括：首先，在一个配置授权资源CG1到达时，终端设备从网络设备预先分配的多个混合自动重传请求(hybrid automatic repeat request，HARQ)进程中，选取该配置授权资源CG1关联的HARQ进程；然后，终端设备将待传输数据组成数据包，以保存到该关联的HARQ进程的缓存中，以使该HARQ进程将该数据包在配置授权资源CG1上传输出去；当该HARQ进程未将该数据包在配置授权资源CG1上传输出去时，终端设备可以等待后续到达的配置授权资源CG2，从而将配置授权资源CG2与该HARQ进程关联，使得该HARQ进程将该数据包在配置授权资源CG2上传输出去。在这种实现方式中，终端设备需要等待后续到达的配置授权，进而在该配置授权上发送未传输成功的数据包，增加了数据传输的时延。
为了解决上述技术问题，本申请实施例提供了一种通信方法，当配置授权关联的第一HARQ进程中缓存的第一数据未传输时，终端设备将该第一HARQ进程的信息发送网络设备，以使终端设备根据该第一HARQ进程的信息为该第一HARQ进程分配上行授权，终端设备可以通过该上行授权传输该第一数据。如此，不需要通过后续到达的配置授权对该第一数据进行传输，从而降低了数据传输的时延。
下面通过一些实施例对本申请的技术方案进行详细说明。图2为本申请实施例提 供的一种通信方法的流程示意图，本实施例涉及的是网络设备和终端设备之间进行数据传输的具体过程。如图2所示，该方法可以包括：S201、S202和S203。
S201、当第一授权关联的第一混合自动重传请求HARQ进程的缓存中存在未传输的第一数据时，终端设备向网络设备发送第一HARQ进程的信息，该第一授权为第一配置授权。对应的，网络设备接收来自终端设备的第一混合自动重传请求HARQ进程的信息。
其中，第一配置授权可以分为以下两种类型。
第一类：网络设备通过RRC消息中的参数(例如ConfiguredGrantConfig)为终端设备配置CG的传输参数，例如配置以下参数中的一种或多种：周期、开环功控相关参数、波形、冗余版本、冗余版本序列、重复次数、跳频模式、资源分配类型、HARQ进程数、解调参考信号(demodulation reference signal，DMRS)相关参数、调制编码方案(modulation and coding scheme，MCS)表格、资源块组(resource block group，RBG)大小、时域资源位置、频域资源位置。
第二类：网络设备通过无线资源控制(Radio Resource Control，RRC)消息向终端设备配置部分或全部传输参数，例如配置以下参数中的一种或多种：时域资源的周期、开环功控相关参数、波形、冗余版本、冗余版本序列、重复次数、跳频模式、资源分配类型、MCS表格、DMRS相关参数、和HARQ进程数；并且，网络设备向终端设备发送物理层信令，例如下行控制信息(downlink control information，DCI)，来激活该第二类CG。可选地，该DCI还可以用于配置部分传输参数，例如配置以下参数中的一种或多种：时域资源位置、频域资源位置、DMRS相关参数、和MCS。该DCI可以是通过物理下行控制信道(physical downlink control channel，PDCCH)携带的。
当终端设备使用上述两类CG进行上行传输时，终端设备可以直接使用网络设备预先配置的CG向网络设备发送上行数据，而不需要向网络设备发送调度请求(Scheduling Request，SR)并等待网络设备的动态授权。需要说明的是，该第二类CG需要被物理层信令激活后才能被终端设备使用。
第一HARQ进程是该第一配置授权关联的HARQ进程，当该第一HARQ进程的缓存中存在未传输的数据时，终端设备向网络设备发送该第一HARQ进程的信息。在本申请实施例中，第一HARQ进程的信息可以包括第一HARQ进程的标识。
可选地，当存在多个上述第一HARQ进程时，终端设备向网络设备发送多个第一HARQ进程的信息。
在本申请实施例中，将已经存储到HARQ进程的缓存中的数据但未传输的数据称为第一数据，其中，该第一数据可以是以媒介控制协议(Medium Access Control，MAC)协议控制单元(Protocol Data Unit，PDU)的形式存在。配置授权是周期性的，当第一授权到达时，可以理解为该第一授权在当前时间可以被使用，此时终端设备会将待发送数据组成MAC PDU，并将MAC PDU存储至HARQ进程的缓存中，但在如下情况1和情况2下，该MAC PDU未被发送。
情况1、第一授权和第三授权在时域上有重叠，且，第一授权的优先级低于第三授权的优先级。其中，该第三授权可以为动态授权或配置授权。
可以理解的是，第一授权和第三授权在时域上有重叠也可以理解为第一授权和第三授权在时域上冲突，当第一授权满足上述情况1时，终端设备优先将第三授权上的待传输数据进行传输，其中，第三授权上的待传输数据为存储到第三授权关联的HARQ进程的缓存中的MAC PDU。
上述第一授权的优先级可以通过第一授权关联的第一HARQ进程的缓存中的MAC PDU中的数据确定，具体优先级由如下其中一种信息确定：承载该数据的逻辑信道(logical channel，LCH)的优先级、该数据包括的MAC控制单元的优先级和该数据的服务质量(quality of service，QoS)信息。
上述服务质量信息可以包括但不限于：时延、丢包率、误码率、可靠性。由于服务质量信息的取值通常是连续的，优先级通常是非连续的，从而可以将服务质量信息按照取值范围与优先级映射，例如，对于正向参数的服务质量信息，可以参照如下公式将服务质量信息映射为优先级：
Figure PCTCN2020122516-appb-000001
其中，P为优先级，优先级分为三个P1、P2和P3，并且P1低于P2，P2低于P3，QOS为服务质量信息，QOS1、QOS2为两个固定的服务质量信息取值，并且QOS1<QOS2。
可以理解的是，上述公式中的优先级个数为3个，在实际应用中，公式可以根据优先级个数灵活调整，本申请实施例对其不加限制。
情况2、第一授权对应的信道非空闲。
信道是否空闲可以通过前述LBT机制检测，本申请实施例在此不再赘述。
在上述两种情况下，终端可以将第一HARQ进程的信息发送给网络设备。具体地，终端设备通过第二授权向网络设备发送第一HARQ进程的信息。
可选地，第二授权可以为动态授权或配置授权。可选地，第二授权可以与第三授权相同或不同。
可选地，第二授权和第一授权位于相同或不同的小区。当第二授权和第一授权位于不同的小区时，第一HARQ进程的信息还包括第一授权所在小区的小区标识。此时，网络设备可以根据该小区标识在第一授权所在小区上为终端设备动态调度上行授权，并将该上行授权与第一HARQ进程关联。当第一HARQ进程消息没有携带小区标识时，网络设备在接收到终端设备通过第二授权发送的第一HARQ进程的信息时，可以默认在第二授权所在小区上调度上行授权，并将该上行授权与第一HARQ进程关联。
通过上述第二授权向网络设备发送第一HARQ进程的信息的过程中，可以根据第二授权的类型确定承载第一HARQ进程的信息的数据，其中，第二授权的类型包括：配置授权和动态授权两种。
在本申请实施例的一种示例中，当第二授权为配置授权时，第一HARQ进程的信息承载在上行控制信息中；或者，当第二授权为配置授权时，第一HARQ进程的信息承载在第二数据中，该第二数据是新传的数据，第二数据与第一数据不同。
在本申请实施例的另一种示例中，当第二授权为动态授权时，第一HARQ进程的信息承载在第二数据中，该第二数据是新传的数据，第二数据与第一数据不同。
此外，无论第二授权为动态授权还是配置授权，第二授权均可以传输用户数据，从而可以将第一HARQ进程的信息可以承载在该用户数据中，该用户数据可以称为第二数据。第二数据是第二授权上新传的数据。可以理解的是，第一HARQ进程的信息可以位于MAC控制单元(control element，CE)或MAC业务数据单元(service data unit，SDU)中。
可以理解的是，在上述情况1中，第二授权和第三授权可以是同一个上行授权，从而实现了在优先级较低的第一授权和优先级较高的第三授权在时域上冲突的情况下，将第三授权关联的HARQ进程缓存的MAC PDU(第二数据)发送给网络设备，并且在第三授权发送的MAC PDU关联的上行控制信息或第三授权发送的MAC PDU中携带第一HARQ进程的信息。
在上述情况2中，当第一授权对应的信道非空闲时，可以将第二小区的上行授权作为传输第一HARQ进程的信息的第二授权，第二小区可以是第一授权所在的小区，也可以是第一授权所在的小区的相邻小区。当第二授权为配置授权时，将第二授权关联的HARQ进程缓存的MAC PDU发送给网络设备，并且在第二授权的上行控制信息或第二授权发送的MAC PDU中携带第一HARQ进程的信息；当第二授权为动态授权时，将第二授权关联的HARQ进程缓存的MAC PDU发送给网络设备，并且在第二授权发送的MAC PDU中携带第一HARQ进程的信息。
在上述UCI或第二数据中，第一HARQ进程的信息可以是如下形式1和形式2：
形式1、第一HARQ进程的信息包括第一HARQ进程的标识。
形式2、第一HARQ进程的信息为位图，该位图中与第一HARQ进程对应的比特位用于指示第一HARQ进程存在未传输的数据。
可以理解的是，第一HARQ进程的信息可以作为UCI或MAC CE或MAC SDU的一个字段，该字段可以对应固定比特数或不固定比特数。
当第一HARQ进程的信息包括第一HARQ进程的标识时，可以采用第一固定比特数表示第一HARQ进程的标识。例如，若HARQ进程的总数目为16，则第一固定比特数可以为4，以用0000-1111共16种取值代表16个HARQ进程。如此，在存在一个第一HARQ进程时，可以发送第一固定比特数的比特，以代表该第一HARQ进程的标识。
此外，还可以固定传输N个第一固定比特数的比特，用于一次传输N个第一HARQ进程的标识，N为正整数。若实际上第一HARQ进程的数目小于N，则可以将N个第一固定比特数的比特中的剩余比特填充为无效取值。例如，当N为2，第一固定比特数为4，从而可以传输8个比特用于表示两个第一HARQ进程的信息，当N＝2时，如图3所示，需要发送两个字段：HARQID0和HARQID1，分别表示两个第一HARQ进程的信息，并且两者连续用2*第一固定比特数个比特。
需要说明的是，MAC CE或MAC SDU传输N*第一固定比特数个比特，而UCI可以传输N*第一固定比特数个比特，还可以传输不固定数目的比特。
在本申请实施例的一种示例中，当采用UCI承载第一HARQ进程的标识时，终端设备可以在存在缓存中有未传输的第一数据的第一HARQ进程时传输第一HARQ进程的标识，在不存在缓存中有未传输的第一数据的第一HARQ进程时不传输第一HARQ 进程的标识，从而网络设备可以根据接收到的UCI的长度确定UCI中是否存在第一HARQ进程的信息，若UCI的长度为第一预设长度，则确定UCI中不存在第一HARQ进程的标识，若UCI的长度为第二预设长度，则确定UCI中存在第一HARQ进程的标识，并且(第二预设长度-第一预设长度)/第一固定比特数的值，为第一HARQ进程的标识的数目，从而可以根据该数目从第一预设位置中获取第一HARQ进程的标识，其中第一预设长度小于第二预设长度，第一预设长度可以是UCI不包含第一HARQ进程时的固定长度，第二预设长度是UCI包含第一HARQ进程的可变长度。
在本申请实施例的一种示例中，当采用UCI承载第一HARQ进程的标识时，终端设备可以在存在或不存在第一HARQ进程时均在UCI中携带一个或多个第三固定比特数的字段，此外，UCI还会携带其余信息，例如，UCI中还携带共享信息信道占用时间、新数据指示、冗余版本等。每个第三固定比特数＝第一固定比特数+1，多出来的一个比特用于表示该第三固定比特数对应的字段是否为第一HARQ进程的标识，该比特可以称为指示比特，从而网络设备可以根据该比特判断是否存在第一HARQ进程。例如，当第一固定比特数为4时，第三固定比特数为5，若第三固定比特数的字段中第一个比特为指示比特，1代表第三固定比特数对应的字段中包括第一HARQ进程的标识，0代表第三固定比特数对应的字段中不包括第一HARQ进程的标识，则根据第三固定比特数的字段:“10001”中的第一个比特“1”确定比特“0001”为第一HARQ进程的标识；根据第三固定比特数的字段“00001”中的第一个比特“0”确定比特“0001”不为第一HARQ进程的标识，该第三固定比特数的字段中不存在第一HARQ进程的标识。
当第一HARQ进程的信息为位图时，UCI或MAC CE或MAC SDU均可以携带该位图，该位图中存在第二固定比特数的比特，第二固定比特数可以是HARQ进程的总数，当比特位为1时，表示该比特位对应的HARQ进程存在未传输的数据，也就是该比特位对应的HARQ进程为第一HARQ进程；当比特位为0时，表示该比特位对应的HARQ进程不存在未传输的数据，也就是该比特位对应的HARQ进程不为第一HARQ进程，如此，当不存在第一HARQ进程时位图的各比特位均为0，当所有进程均为第一HARQ进程时位图的各比特位均为1。例如，若HARQ进程的总数为16，则第二固定比特数为16，如图4所示的位图格式，一种可能的方式，但不做限定，HARQ进程的比特位按照如下顺序排列：HARQ15、HARQ14、HARQ13、…、HARQ0，当HARQ15和HARQ13为第一HARQ进程时，可以得到位图的具体取值为：1010000000000000。当然，还可以将比特位为0设定为表示该比特位对应的HARQ进程存在未传输的数据，将比特位为1设定为表示该比特位对应的HARQ进程不存在未传输的数据。可以预先设定位图中的每个比特位与HARQ进程的映射关系，从而网络设备可以根据位图中的比特位确定第一HARQ进程的标识。
可以看出，采用位图表示第一HARQ进程的信息时，UCI或MAC CE或MAC SDU中会多出第二固定比特数个比特，在第一HARQ进程较少时，采用第一HARQ进程的标识作为第一HARQ进程的信息占用较少字节数；在第一HARQ进程较多时，采用位图作为第一HARQ进程的信息占用较少字节数。在实际应用中，可以在不同场景下灵活选取第一HARQ进程的信息形式，本申请实施例对其不加以限制。例如，在重传 HARQ频发的场景下，可以采用位图作为第一HARQ进程的信息；在重传HARQ较少的场景下，可以采用第一HARQ进程的标识作为第一HARQ进程的信息。
S202、网络设备向终端设备发送上行授权，该上行授权关联第一HARQ进程。对应的，终端设备接收来自网络设备的上行授权。
网络设备根据第一HARQ进程的信息为该第一HARQ进程分配一个上行授权，由于该上行授权是根据终端设备发送的第一HARQ进程的信息动态分配的，从而该上行授权也可以称为动态授权。
网络设备在分配上行授权之后，可以将上行授权的时域位置发送给终端设备，以使终端设备根据该时域位置使用该上行授权。此外，还可以将MCS等参数也一同发送给终端设备，以使终端设备可以采用该上行授权预设的MCS进行数据传输。
在本申请实施例的一种示例中，网络设备可以将上行授权的时域位置、MCS等参数通过一个独立的消息发送给终端设备；还可以将上行授权的时域位置、MCS等参数添加到DCI中，并将DCI发送给终端设备。
S203、终端设备通过上行授权传输第一数据。对应的，网络设备接收来自终端设备的第一数据。
具体地，终端设备将第一HARQ进程的缓存中的第一数据通过S202中网络设备分配的上行授权传输给网络设备。
