Description

本申请要求于2019年2月14日提交国家知识产权局、申请号为201910115218.4、申请名称为“一种上行传输方法及通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉通信领域，尤其涉及一种上行传输方法及通信装置。
背景技术
长期演进(long term evolution，LTE)系统中为了提高数据发送效率，支持自动上行传输(autonomous uplink，AUL)。不需要基站的调度，终端可以直接在AUL资源上发送上行数据。基站可以为终端配置一些用于AUL的子帧以及用于AUL的混合自动重传请求(hybrid automatic repeat request，HARQ)进程。
终端在服务小区配置AUL资源的子帧上，可以从基站预配置的HARQ进程中随机选择一个HARQ进程进行上行传输。但是，终端选择的HARQ进程可能无法进入新传，对通信系统的传输性能造成影响。
发明内容
本申请实施例提供一种上行传输方法及通信装置，保证终端正常进入新传。
为达到上述目的，本申请实施例采用如下技术方案：
第一方面，公开了一种上行传输方法，包括：
终端在配置了自动上行传输资源的子帧上使用第一HARQ进程传输上行数据时，认为第一HARQ进程的新传标识(new data indicator，NDI)是翻转的，其中，第一HARQ进程是可用于自动上行传输的HARQ进程，且在子帧之前，递交到HARQ实体的上行授权中不存在第一HARQ进程的上行授权。终端还可以使用第一HARQ进程在所述子帧上进行上行数据新传。
本申请实施例提供的上行传输方法中，终端在服务小区配置AUL资源的子帧上使用第一HARQ进程发数据时，如果第一HARQ进程在这个子帧之前没有进行过传输，终端则认为所述第一HARQ进程的NDI是翻转的。进而，终端在所述子帧上可以进入新传，利用所述第一HARQ进程进行上行数据传输。本申请实施例提供的方法解决了某些预配置的可用于自动上行传输的HARQ进程在初始传输时不能进入新传流程，无法利用自动上行传输资源进行上行传输的问题，避免由此造成的资源浪费。

本申请实施例中，如果某个HARQ满足第一条件，终端可以将HARQ进程的HARQ反馈值设置为肯定应答。根据现有协议，HARQ反馈值设置为肯定应答的HARQ进程的NDI认为是翻转的，因此，终端可以认为HARQ进程的NDI是翻转的，从而在某个配置了上行自动传输资源的子帧上，使用满足第一条件的HARQ进程可以进入上行数据新传。

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。
图1给出了本申请提供的技术方案所适用的一种通信系统的示意图，该通信系统可以包括一个或多个网络设备100(仅示出了1个)以及与每一网络设备100连接的一个或多个终端200。图1仅为示意图，并不构成对本申请提供的技术方案的适用场景的限定。
网络设备100可以是传输接收节点(transmission reception point，TRP)、基站、中继站或接入点等。网络设备100可以是5G通信系统中的网络设备或未来演进网络中的网络设备；还可以是可穿戴设备或车载设备等。另外还可以是：全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)网络中的基站收发信台(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的NB(NodeB)，还可以是长期演进(long term evolution，LTE)中的eNB或eNodeB(evolutional NodeB)。网络设备100还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器。本申请下文将以基站为例进行说明。
终端200可以是用户设备(user equipment，UE)、接入终端、UE单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端、无线通信设备、UE代理或UE装置等。接入终端可以是蜂窝电话、无绳电话、会话发起协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5G网络中的终端或未来演进的公共陆地移动网络(public land mobile network，PLMN)网络中的终端等。
图1所示通信系统中，网络设备100、终端200上可以部署多根天线，利用MIMO进行通信，显著提高无线通信系统的性能。在一些实现方式中，网络设备100为发射端设备、终端200为接收端设备；在另一种可能的实现方式中，终端200为发射端设备、网络设备100为接收端设备。
为了充分利用非授权频谱，基站可以通过非授权频谱给UE发送下行数据，UE可以通过非授权频谱给基站发送上行数据。发送端在发送数据之前都需要做先听后发(listen before talk，LBT)，也就是只有监听到信道空闲才可以发送数据。为了提高数据发送效率，减少做LBT的次数，LTE系统支持AUL，终端可以不需要基站的调度直接在AUL资源上发送上行数据。
以下首先对本申请实施例涉及的术语进行解释说明，具体如下：
(1)HARQ进程
通常，终端可以通过上行授权(uplink grant，UL grant)指示的资源进行上行传输。上行授权可以是基站动态调度的，也可以是预配置的。具体地，终端可以使用HARQ进程(process)在上行授权指示的资源上进行上行传输。例如，将HARQ进程的上行授权递交到HARQ实体，使得数据能够在HARQ进程的上行授权指示的资源上被发送。
需要说明的是，一个HARQ实体可以维护多个并行的HARQ进程，每个HARQ进程都有一个HARQ ID，通过HARQ ID可以区分不同的HARQ进程。
另外，有些HARQ进程需要维护一个状态变量——HARQ反馈(HARQ_FEEDBACK)， 终端可以根据HARQ进程所接收到的HARQ反馈值，将HARQ进程的HARQ反馈值置为肯定应答(acknowledgement，ACK)或否定应答(negative acknowledgement，NACK)。
(2)NDI
每个HARQ进程会维护一个NDI。在一种可能的实现方式中，NDI为1比特，通过这个比特的取值来指示终端使用HARQ进程进行新传还是重传。如果HARQ进程的NDI的值较上一次发生了翻转，则表示终端可以使用HARQ进程传输新的数据，如果NDI的值没有发生翻转，则表示终端可以使用HARQ进程重传数据。
示例的，如果HARQ进程的NDI从“0”翻转为了“1”，则表示终端可以使用该HARQ进程进行新传。
(3)AUL
AUL是利用非授权频谱资源进行的上行传输，无需基站的调度，终端也可以在AUL资源上进行上行传输。通常，基站可以通过无线资源控制(radio resource control，RRC)信令向终端下发AUL配置，AUL配置是服务小区级的配置。具体地，基站通过RRC信令为终端配置了某个服务小区用于AUL的HARQ进程，以及用于AUL的子帧等。本申请实施例中，上述RRC信令可以认为是自动上行传输配置消息；用于AUL的子帧，可以认为是配置AUL资源的子帧；用于AUL的HARQ进程可以认为是预配置的可用于自动上行传输的HARQ进程。另外，基站还可以向终端发送自动上行传输激活消息，终端接收自动上行传输激活消息时，在上述用于AUL的HARQ进程中随机选择一个HARQ进程，并认为该HARQ进程的NDI是翻转的。可以将终端收到自动上行传输激活消息时选择的HARQ进程称为初始选择HARQ进程。
目前，支持终端在AUL资源上进行新传，也支持终端在AUL资源上进行重传。对于某个HARQ进程来说，终端可以判断该HARQ进程的NDI是否翻转，以确定使用该HARQ进程在服务小区配置AUL资源的子帧上进行新传还是重传。具体地，如果某个子帧配置了AUL资源，并且终端为该子帧选择的HARQ进程为上述初始选择HARQ进程，由于初始选择HARQ进程的NDI是翻转的，终端在这个子帧上可以进入新传，利用AUL资源向基站新传数据。如果终端为该子帧选择了基站预配置的可用于AUL的HARQ进程中，除上述初始选择HARQ进程外的其他HARQ进程，根据现有协议规定，这些HARQ进程的NDI可能不能认为是翻转的，终端在当前子帧不能进入新传流程。
本申请实施例提供的上行传输方法中，终端在服务小区配置AUL资源的子帧上使用第一HARQ进程发数据时，如果第一HARQ进程是预配置的可用于自动上行传输的HARQ进程，且在所述子帧之前，递交到HARQ实体的上行授权中不存在所述第一HARQ进程的上行授权，即所述第一HARQ进程在所述子帧之前没有进行过传输，在所述子帧上进行的传输对于所述第一HARQ进程来说是初始传输，终端则认为所述第一HARQ进程的NDI是翻转的。进而，终端在所述子帧上可以进入新传，利用所述第一HARQ进程进行上行数据传输。本申请实施例提供的方法解决了某些预配置的可用于自动上行传输的HARQ进程在初始传输时不能进入新传流程，无法利用AUL资源进行上行传输的问题，避免由此造成的资源浪费。
在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次 序进行限定。

其中，处理器201可以通过运行或执行存储在存储器202内的软件程序，以及调用存储在存储器202内的数据，执行通信装置的各种功能。
在具体的实现中，在一些实施例中，处理器201可以包括一个或多个CPU，例如图2中所示的CPU0和CPU1。
在具体实现中，在一些实施例中，通信装置可以包括多个处理器，例如图2中所示的处理器201和处理器205。这些处理器中的每一个可以是一个单核处理器(single-CPU)，也可以是一个多核处理器(multi-CPU)。这里的处理器可以指一个或多个通信装置、电路、和/或用于处理数据(例如计算机程序指令)的处理核。
存储器202可以是只读存储器(read-only memory，ROM)或可存储静态信息和指令的其他类型的静态存储通信装置，随机存取存储器(random access memory，RAM)或者可存储信息和指令的其他类型的动态存储通信装置，也可以是电可擦可编程只读存储器(electrically erasable programmable read-Only memory，EEPROM)、只读光盘(compact disc read-only memory，CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其他磁存储通信装置、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质，但不限于此。存储器202可以是独立存在，通过通信总线204与处理器201相连接。存储器202也可以和处理器201集成在一起。

需要说明的是，配置了自动上行传输资源的子帧可以终端的服务小区配置了自动上行传输资源的子帧，自动上行传输资源可以是本申请实施例所述的AUL。终端接收来自基站的自动上行传输配置消息，可以根据自动上行传输配置消息确定服务小区配置AUL资源的子帧以及可用于自动上行传输的HARQ进程。其中，自动上行传输配置消息可以是RRC信令。
另外，本申请实施例中AUL资源还可以是其他可用于上行传输的预配置授权资源，即无需基站的动态调度终端就可以在上述可用于上行传输的预配置授权资源上发送上行数据，例如，包括但不限于5G(5th generation)系统中的configured grant type1和configured grant type2，以及NR-U(new radio-unlicensed)系统中配置的上行资源。服务小区配置AUL资源的子帧可以认为是可用于自动上行传输的子帧。另外，可用于上行传输的免授权资源(例如，AUL资源的)在时域上的配置粒度不仅仅局限于子帧，还可以是其他长度的时间长度或者时域资源单位，例如，物理上行共享信道(physical uplink shared channel，PUSCH)持续时间(PUSCH duration)、符号(symbol)、时隙(slot)、迷你时隙(mini-slot)、调度时间间隔(TTI)、sTTI等。
需要说明的是，网络设备可以通过以下两种方式配置上述预配置授权资源(也可以称为预配置UL grant)：
第一种、网络设备可以通过半静态资源分配的方式预配置终端上行传输所需的资源，即预配置UL grant(也可以称为预配置授权资源)。应理解的是，所述预配置UL grant可以按周期出现，不需要终端每次发送上行传输前都先获得上行授权。例如，网络设备可以通过RRC信令配置上行传输的UL grant。RRC信令还可以包括预配置UL grant的周期，从而终端可以在预配置UL grant上传输。
第一种配置方式可以称为配置授权方式1(configured grant type 1)。
第二种、网络设备可以通过RRC信令配置上行传输的部分信息，例如，预配置UL grant的周期等。另外，网络设备通过物理层信令携带预配置UL grant，该物理层信令还用于激活预配置UL grant，从而终端可以在预配置UL grant上传输。
第二种配置方式可以称为配置授权方式2(configured grant type 2)。
需要说明的是，上述第一种配置方式的命名不仅仅局限于配置授权方式1，还可以有其他命名，本申请实施例对此不作限制。同样，第二种配置方式的命名也不仅仅局限于配置授权方式2，还可以有其他命名。本申请实施例对第一种配置方式、第二种配置方式适用的通信系统也不做限制，可以是LTE通信系统，也可以是5G通信系统，也可以是其他通信系统。
另外，在本申请实施例中，“上行授权”可理解为用于调度物理上行资源的信令，例如， 用于上行授权的下行控制信息，或者，用于半静态配置的RRC信令，或者，在半静态配置方式中用于激活上行授权资源的下行控制信息等。在LTE或NR协议中，“上行授权”都可对应为UL grant，本领域的技术人员可理解其含义。
具体实现中，终端可以根据基站下发的自动上行传输配置消息(例如RRC信令)中的aul-HARQ-Processes参数确定服务小区可用于自动上行传输的HARQ进程，根据自动上行传输配置消息中的aul-Subframes参数确定服务小区配置AUL资源的子帧。示例的，aul-HARQ-Processes参数指示的HARQ ID为0、1、3、4、6、7，即HARQ ID为0、1、3、4、6、7的六个HARQ进程可用于自动上行传输。
其中，aul-Subframes参数用于指示服务小区配置AUL资源的子帧满足的条件。具体地，aul-Subframes参数可以是长度为40比特的序列，根据aul-Subframes参数可以确定哪些子帧配置了AUL资源。该序列的每个比特对应一个子帧。其中，比特取值为1表示该子帧上配置了AUL资源，比特取值为0表示该子帧上未配置AUL资源。aul-Subframes参数最左侧的比特位指示的是满足“SFN mod 4＝0”的无线帧中的子帧0上是否配置了AUL资源，其中，“SFN mod 4＝0”，即无线帧的帧号除以4余数为0，如帧0、4、8、12等。以此类推，aul-Subframes参数可以指示连续的40个子帧上AUL资源的配置情况。以SFN＝0的无线帧为例，aul-Subframes参数最左侧的比特指示无线帧0的子帧0是否配置了AUL资源，aul-Subframes参数可以指示从无线帧0的子帧0开始的连续40个子帧是否配置了AUL资源，即无线帧0～无线帧3包括的40个子帧的配置情况。示例的，参考图4，aul-Subframes参数的前十个比特为1001111100，即无线帧0的子帧0、3、4、5、6、7上配置了AUL资源。
又如，aul-Subframes参数最左侧的比特也可以是指示无线帧4的子帧0是否配置了AUL资源，进而aul-Subframes参数可以指示从无线帧4的子帧0开始的连续40个子帧是否配置了AUL资源，即无线帧4～无线帧7包括的40个子帧的配置情况。
需要说明的是，自动上行传输配置消息中并没有携带用于自动上行传输的上行资源的时频资源的信息，可于自动上行传输的上行资源的时频资源的信息是通过物理下行控制信道(physical downlink control channel，PDCCH)发送给终端的。具体地，这个PDCCH可以用于承载自动上行传输激活消息，包括用于自动上行传输的上行资源的时频资源的信息。终端接收自动上行传输激活消息时保存PDCCH中的用于自动上行传输的上行资源时频资源的信息，在自动上行传输配置消息指示的可用于自动上行传输的子帧上可以使用上述用于自动上行传输的时频资源的信息指示的时频资源，如：UL grant。
在某个服务小区收到自动上行传输激活消息后，终端在每一个子帧查看该服务小区在该子帧上是否配置有AUL资源。如果子帧配置了AUL资源，终端则在预配置的可用于自动上行传输的HARQ进程中选择一个，并根据选择的HARQ进程的NDI是否翻转来判断能否进入新传。本申请实施例中，配置AUL资源的子帧与HARQ进程没有绑定关系，终端可以在基站预配置的可用于自动上行传输的HARQ进程中，随机选择一个HARQ进程。具体地，终端为某个配置AUL资源的子帧(以下简称第一子帧)选择的HARQ进程主要分为以下三类：
第一类、初始选择HARQ进程。
AUL是先配置后激活的，终端根据来自基站的自动上行传输配置消息确定可用于自动 上行传输的HARQ进程，终端接收自动上行传输激活消息后，可以使用这些HARQ进程通过AUL资源进行上行传输。
另外，终端接收自动上行传输激活消息时，可以随机翻转一个HARQ进程的NDI，这个HARQ进程即为初始选择HARQ进程。示例的，终端接收自动上行传输激活消息时，翻转第二HARQ进程的NDI；第二HARQ进程为终端根据自动上行传输配置确定的可用于自动上行传输的HARQ进程。
由于初始选择HARQ进程的NDI是翻转的，因此终端在第一子帧上使用该HARQ进程能进入新传，利用AUL资源向基站发送数据。
第二类、使用过的HARQ进程。
所谓使用过的HARQ进程，即在第一子帧之前，这些HARQ进程进行过传输，或者这些HARQ进程在第一子帧上正在进行传输。其中，HARQ进程进行的传输可以是动态grant调度的上行传输；或者，利用AUL资源进行的上行传输。对于这类HARQ进程，在第一子帧对应的时刻，它们的HARQ反馈值可以为ACK或NACK。
如果终端为第一子帧选择的HARQ进程的HARQ反馈值为ACK，则认为该HARQ进程的NDI是翻转的，因此终端能够在第一子帧上进入新传，利用AUL资源进行新传，向基站发送新的数据。
如果为第一子帧选择的HARQ进程的HARQ反馈值为NACK，终端在该子帧上使用这个HARQ进程向基站重传数据。
第三类、未使用过的HARQ进程。
所谓未使用过的HARQ进程，即终端为第一子帧所选的HARQ进程，在第一子帧之前未进行过传输。例如，HARQ进程未被用于动态grant调度的上行传输，也没有被用于AUL资源的上行传输。对于这类HARQ进程，在第一子帧之前，由于HARQ进程没有进行过传输，所以HARQ进程没有HARQ反馈值。
具体实现中，终端可以在要使用第一子帧的时候为第一子帧选择HARQ进程，也可以在使用第一子帧之前的其他时机为第一子帧选择HARQ进程，本申请实施例对此不做限制。
根据现有技术，如果终端为第一子帧选择的HARQ进程属于第三类HARQ进程，由于该HARQ进程的HARQ反馈值不是ACK，所以终端不能认为该HARQ进程的NDI翻转了，因此终端在第一子帧上不能进入新传。
本申请实施例提供的方法主要用于解决终端选择第三类HARQ进程，不能进入新传流程的问题。也就是说终端在服务小区配置AUL资源的子帧上使用上述第三类HARQ进程(如本申请实施例所述的第一HARQ进程)发送数据时，终端认为HARQ进程的NDI是翻转的，终端在所述子帧上可以进入新传。
需要说明的是，终端在使用HARQ进程进行上行传输时，终端的物理层首先将上行授权(如：基站动态调度的UL grant或配置的AUL grant)递交给HARQ实体，然后HARQ实体将上行授权递交给相应的HARQ进程，并指示HARQ进程做新传或者重传。因此，终端可以通过如下方式判断为某个配置AUL资源的子帧选择的HARQ进程是否被使用过(即选择的HARQ进程是否为上述第三类HARQ进程)：如果为服务小区配置AUL资源的子帧选择了第一HARQ进程，并且在该子帧之前，递交到HARQ实体的上行授权中不存在第一HARQ进程的上行授权，也就是说HARQ实体中没有递交给第一HARQ进程上 行授权，因此可以判断在该子帧之前，第一HARQ进程没有做过上行传输，即为未使用过的HARQ进程。也就是说，在该子帧上进行的传输是第一HARQ进程的初始传输。
具体实现中，终端为某个服务小区配置AUL资源的子帧选择了一个HARQ进程，一旦判断这个HARQ进程为上述第三类HARQ进程，即在这个子帧之前递交到HARQ实体的上行授权中不存在这个HARQ进程的上行授权，终端则认为这个HARQ进程的NDI是翻转的，因此终端可以在这个子帧上使用这个HARQ进程进行新传。另外，终端认为HARQ进程的NDI是翻转的，可以是终端将HARQ进程的NDI翻转。示例的，将HARQ进程的NDI从“0”翻转为“1”。
另一种可能的实现方式中，终端为某个服务小区配置AUL资源的子帧选择一个HARQ进程，一旦判断这个子帧之前递交到HARQ实体的上行授权中不存在这个HARQ进程的上行授权，则将这个HARQ进程的HARQ反馈值设置为ACK。进而，根据现有协议的规定，由于HARQ进程的HARQ反馈值为ACK，终端认为这个HARQ进程的NDI是翻转的，可以在这个子帧上使用这个HARQ进程进行新传。
示例的，参考图5，预配置的可用于自动上行传输的HARQ进程为HARQ进程0、HARQ进程1、HARQ进程3、HARQ进程5以及HARQ进程7。终端还可以确定服务小区配置AUL资源的子帧为0、2、3、5。终端接收到自动上行传输激活消息时，AUL配置生效，另外，终端翻转了HARQ进程0的NDI。如果终端要发送上行数据，最早可用的子帧就是子帧0，假如终端选择HARQ进程0进行上行传输，由于HARQ进程0的NDI是翻转的，因此可以正常进入新传。如果终端选择了其他HARQ进程，比如HARQ进程1、3、5、7，也能正常进入新传流程。
假设终端选择了HARQ进程3，且在子帧0之前HARQ进程3被使用过，且HARQ进程3的HARQ反馈值为ACK，终端使用HARQ进程3可以正常进入新传。假设终端选择了HARQ进程4，且在子帧0之前HARQ进程4未被使用过，终端则认为HARQ进程4的NDI是翻转的，或者，将HARQ进程4的HARQ反馈值设置为ACK，终端使用HARQ进程4也可以正常进入新传。
302、终端使用第一HARQ进程在所述子帧上进行上行数据新传。
本申请实施例中，虽然第一HARQ进程在步骤301所述的子帧之前未进行过传输，但是终端认为第一HARQ进程的NDI是翻转的，因此终端可以使用第一HARQ进程，在这个子帧上利用AUL资源进行新传。
需要说明的是，终端使用第一HARQ进程在所述子帧上进行上行数据新传，即终端使用第一HARQ进程在所述子帧上传输的数据是这些数据的首次传输。
可选的，终端在接收自动上行传输激活消息时，可以不翻转某个HARQ进程的NDI，进而终端在某个配置AUL资源的子帧选择的HARQ进程包括两类：使用过的HARQ进程以及未使用过的HARQ进程，即上述第二类HARQ进程和第三类HARQ进程。对于使用过的HARQ进程，如果HARQ反馈值是ACK，终端可以使用这些HARQ进程在这个子帧上进行新传，对于未使用过的HARQ进程，终端无法使用这些HARQ进程在这个子帧上进行新传。本申请实施例中，如果终端在某个配置AUL资源的子帧选择的HARQ进程，在这个子帧之前没有被使用过，终端则认为这个HARQ进程的NDI是翻转的，或者，将这个HARQ进程的HARQ反馈值设置为ACK，进而终端可以使用这个HARQ进程在这个 子帧上进行新传，避免无法进入新传造成的资源浪费。
本申请实施例还提供一种上行传输方法，可以应用于图1所示的通信系统，如图6所示，所述方法包括以下步骤：
601、终端在第一时刻，认为满足第一条件的HARQ进程的NDI是翻转的。第一时刻为接收自动上行传输配置消息的时刻或接收自动上行传输激活消息的时刻，第一条件可以为所述HARQ进程为预配置的可用于自动上行传输的HARQ进程。
需要说明的是，终端接收基站发送的自动上行传输配置消息，可以根据自动上行传输配置消息确定服务小区配置AUL资源的子帧以及可用于自动上行传输的HARQ进程。自动上行传输配置消息用于配置自动上行传输资源，自动上行传输激活消息用于激活自动上行传输资源。
一种可能的实现方式中，终端在接收自动上行传输配置消息时，只要HARQ进程是预配置的可用于自动上行传输的HARQ进程，终端就认为该HARQ进程的NDI是翻转的。因此，接收自动上行传输配置消息时，可以认为预配置的所有可用于自动上行传输的HARQ进程的NDI均为翻转的。
另一种可能的实现方式中，终端在接收自动上行传输激活消息时，只要HARQ进程是预配置的可用于自动上行传输的HARQ进程，终端就认为该HARQ进程的NDI是翻转的。因此，在接收自动上行传输激活消息时，终端可以认为预配置的所有可用于自动上行传输的HARQ进程的NDI均为翻转的。
具体实现中，终端在第一时刻一旦判断某个HARQ进程满足第一条件，就认为该HARQ进程的NDI是翻转的。或者，终端在第一时刻，将满足所述第一条件的HARQ进程的HARQ反馈值设置为肯定应答，根据所述肯定应答认为满足所述第一条件的HARQ进程的NDI是翻转的。
602、终端在配置了自动上行传输资源的子帧上，使用满足所述第一条件的HARQ进程进行新传。
需要说明的是，配置了自动上行传输资源的子帧可以终端的服务小区配置了自动上行传输资源的子帧，自动上行传输资源可以是本申请实施例所述的AUL。
可选的，所述第一条件还包括：在第一时刻，递交到HARQ实体的上行授权中不存在所述HARQ进程的上行授权，且在第一时刻之前，递交到HARQ实体的上行授权中不存在所述HARQ进程的上行授权。
也就是说，终端在第一时刻，认为在第一时刻之前没有被使用过的HARQ进程的NDI是翻转的，以及没有正在被使用的HARQ进程的NDI是翻转的。示例的，假设一个帧包括的10个子帧从0开始编号，分别为子帧0、子帧1……子帧9。终端在子帧2接收自动上行传输配置消息或在子帧2接收自动上行传输激活消息，即第一时刻为子帧2。自动上行传输配置消息指示的可用于自动上行传输的HARQ进程为0、1、3、5，假设HARQ进程1在子帧0被使用过，HARQ进程3在子帧2正在被使用，终端则确定HARQ进程为0、5为满足第一条件的HARQ进程，认为HARQ进程为0、5的NDI是翻转的。
可选的，所述第一条件还包括：在第一时刻，递交到HARQ实体的上行授权中不存在所述HARQ进程的上行授权。
也就是说，终端在第一时刻，认为没有正在被使用的HARQ进程的NDI是翻转的。 示例的，终端在子帧2接收自动上行传输配置消息或在子帧2接收自动上行传输激活消息，即第一时刻为子帧2。自动上行传输配置消息指示的可用于自动上行传输的HARQ进程为0、1、3、5，假设HARQ进程3在子帧2正在被使用，终端则确定HARQ进程为0、1、5为满足第一条件的HARQ进程，认为HARQ进程为0、1、5的NDI是翻转的。
可选的，所述第一条件还包括：在第一时刻之前，递交到HARQ实体的上行授权中不存在所述HARQ进程的上行授权。
也就是说，终端在第一时刻，认为在第一时刻之前没有被使用的HARQ进程的NDI是翻转的。示例的，终端在子帧2接收自动上行传输配置消息或在子帧2接收自动上行传输激活消息，即第一时刻为子帧2。自动上行传输配置消息指示的可用于自动上行传输的HARQ进程为0、1、3、5，假设在子帧2之前，只有HARQ进程0被使用过。具体地，HARQ进程0在子帧0被使用过，终端则确定HARQ进程为1、3、5为满足第一条件的HARQ进程，认为HARQ进程为1、3、5的NDI是翻转的。
需要说明的是，第一时刻还可以是从终端接收自动上行传输配置消息的时刻T 1到终端开始使用AUL资源的时刻T 2之间的任意一个时刻。终端开始使用AUL资源的时刻T 2是终端接收自动上行传输激活消息后第一个配置AUL资源的子帧的起始时刻。示例的，参考图7，无线帧0中配置AUL资源的子帧为0、3、5，无线帧1中配置AUL资源的子帧为1、3、5、7。终端在无线帧0的子帧2(记为时刻T1)接收到自动上行传输配置消息，在无线帧1的子帧2(记为时刻T 3)接收到自动上行传输激活消息，无线帧1的子帧2之后第一个配置AUL资源的子帧为无线帧1的子帧3，因此终端开始使用AUL资源的时刻T 2为无线帧1的子帧3的起始时刻。
本申请实施例中，第一时刻可以是T 1到T 2之间的任意一个时刻，例如，第一时刻为T 1，或者第一时刻为T 3。
需要说明的是，本申请实施例图3所示的方法和本申请实施例图6所示的方法可以独立应用也可以结合使用，本申请实施例对此不作限制。另外，本申请实施例中所述的“认为”，可以是终端具体实施了翻转行为，将HARQ进程的NDI进行翻转，例如，HARQ进程的NDI由0翻转为1，则终端认为HARQ进程的NDI是翻转的。或者，终端也可以不实施翻转行为，认为HARQ进程当前的NDI就是翻转的，也可以进入上行数据新传。
以下结合示例详细介绍本申请实施例提供的方法。示例的，基站通过RRC信令为终端配置的某个服务小区可用于自动上行传输的HARQ进程为HARQ进程0、HARQ进程1、HARQ进程3、HARQ进程4、HARQ进程6以及HARQ进程7。其中，0、1、3、4、6、7指的是HARQ进程的ID。
另外，假设RRC信令的aul-Subframes参数最左侧的比特指示无线帧0的子帧0是否配置了AUL资源，aul-Subframes参数可以指示无线帧0、1、2、3中这个服务小区配置AUL资源的子帧。仅以帧0为例，假设帧0内的子帧0、3、4、5、6、7为这个服务小区配置AUL资源的子帧。
第一种可能的实现方式中，当某个子帧配置了AUL资源，终端可以在这个子帧上利用AUL资源发送上行数据。终端可以在预配置的可用于自动上行传输的HARQ进程里选一个HARQ进程进行上行传输。如果终端确定在该子帧之前，递交到HARQ实体的上行授权中不存在该HARQ进程的上行授权，终端则认为该HARQ进程的NDI是翻转的。
以子帧0为例，如果终端在子帧0选择HARQ进程4进行上行传输。当终端确定在子帧0之前，递交到HARQ实体的上行授权中不存在HARQ进程4的上行授权，则认为在子帧0上进行的传输是HARQ进程4的初始传输，进而认为HARQ进程4的NDI是翻转的。因此，终端在子帧0上可以使用HARQ进程4向基站新传数据。
第二种可能的实现方式中，终端在接收到基站发送的自动上行传输配置消息时，或在接收自动上行传输激活消息时，就将基站预配置的所有可用于自动上行传输的HARQ进程的NDI翻转。
在自动上行传输被激活后，当终端确定某个子帧配置了AUL资源，可以在预配置的可用于自动上行传输的HARQ进程里选一个HARQ进程进行上行传输。由于在接收到自动上行传输配置消息或者自动上行传输激活消息时终端将所有可用于自动上行传输的HARQ进程的NDI翻转了，因此，终端可以正常进入新传。
示例的，终端接收到自动上行传输配置消息时或在接收自动上行传输激活消息时，将基站预配置的HARQ进程0、HARQ进程1、HARQ进程3、HARQ进程4、HARQ进程6以及HARQ进程7的NDI均进行翻转。在子帧0、3、4、5、6、7中的任意一个子帧上，终端从基站预配置的HARQ进程中随机选择一个，HARQ进程的NDI都是翻转的，终端均可以正常进入新传。
第三种可能的实现方式中，终端接收到基站发送的自动上行传输配置消息或者自动上行传输激活消息时，就将基站预配置的所有可用于自动上行传输的HARQ进程中，在此之前未被使用过的、且没有正在被使用的HARQ进程的NDI翻转。
其中，在此之前未使用过的HARQ进程指的是终端接收到自动上行传输配置消息或者自动上行传输激活消息的时刻之前，未被使用过的HARQ进程，即递交到HARQ实体的上行授权中不存在所述HARQ进程的上行授权，如：在此之前未被调度过的HARQ进程。当前正在被使用的HARQ进程可以是，终端接收到自动上行传输配置消息或者自动上行传输激活消息时，正在被上行授权调度使用的HARQ进程，即此刻递交到HARQ实体的上行授权中存在所述HARQ进程的上行授权。
示例的，基站预配置的可用于自动上行传输的HARQ进程为0、1、3、4、6、7，假如终端接收到自动上行传输配置消息或者自动上行传输激活消息时，HARQ进程1和HARQ进程3已经被之前的上行授权使用过了，并且此时没有正在被上行授权使用的HARQ进程，那么终端只需要将HARQ进程0、4、6以及7的NDI翻转即可。
第四种可能的实现方式中，终端接收到自动上行传输配置消息或者自动上行传输激活消息时，将基站预配置的可用于自动上行传输的HARQ进程中，当前没有正在被使用的HARQ进程的NDI翻转。其中，当前正在被使用的HARQ进程可以是，终端接收到自动上行传输配置消息或者自动上行传输激活消息时，正在被上行授权调度使用的HARQ进程，即此刻递交到HARQ实体的上行授权中存在所述HARQ进程的上行授权。
示例的，基站预配置的可用于自动上行传输的HARQ进程为0、1、3、4、6、7，假如终端接收到自动上行传输配置消息或者自动上行传输激活消息时，上行授权正在调度使用HARQ进程0，那么终端就只需要将HARQ进程1、3、4、6和7对应的NDI翻转即可。
需要说明的是，如果HARQ进程1和HARQ进程3在终端接收到自动上行传输配置消息或者自动上行传输激活消息的时刻之前，已经被之前的上行授权使用过了并且HARQ 进程1和HARQ进程3的HARQ反馈值为ACK，即使不翻转HARQ进程1和HARQ进程3的NDI，当终端在配置AUL资源的子帧选择HARQ进程1或HARQ进程3，终端也可以正常进入新传。
第五种可能的实现方式中，终端接收到自动上行传输配置消息或者自动上行传输激活消息时，将基站预配置的可用于自动上行传输的HARQ进程中，在此之前未被使用过的HARQ进程的NDI翻转。
其中，在此之前未被使用过的HARQ进程指的是终端接收到自动上行传输配置消息或者自动上行传输激活消息的时刻之前，未被使用过的HARQ进程，即递交到HARQ实体的上行授权中不存在所述HARQ进程的上行授权，如：在此之前未被调度过的HARQ进程。
示例的，基站预配置的可用于自动上行传输的HARQ进程为0、1、3、4、6、7，假如终端接收到自动上行传输配置消息或者自动上行传输激活消息时，HARQ进程1和HARQ进程3已经被之前的上行授权使用过了，那么终端只需要将HARQ进程0、4、6以及7的NDI翻转即可。
需要说明的是，在上述第一至第五种可能的实现方式中，终端也可以将满足所述条件的HARQ进程的HARQ反馈值置为肯定应答，根据所述肯定应答认为满足所述条件的HARQ进程的NDI是翻转的。
