Description

一种数据传输的方法以及通信设备 技术领域
本申请实施例涉及通信技术领域，具体涉及一种数据传输的方法以及通信设备。
背景技术
随机接入过程是指从终端设备发送随机接入前导码开始尝试接入网络设备到与网络设备间建立起基本的信令连接之前的过程。
随机接入过程分四步完成，每一步称为一条消息(message，Msg)，相关通信标准中将这四个消息称为Msg1、Msg2、Msg3和Msg4。
其中，Msg1为终端设备向网络设备发送的随机接入消息。Msg2为网络设备向终端设备发送的随机接入响应(random access response，RAR)消息。Msg3为终端设备在接收到Msg2后，在网络设备分配的上行传输资源中传输的消息。Msg3支持混合自动重传(hybrid automatic repeat request，HARQ)。
在随机接入过程中也支持用户数据提前传输，可以通过Msg3来提前传输上行数据，即终端设备在向网络设备发送Msg3时一并带上用户数据。
HARQ机制中，终端设备会按照网络设备配置的HARQ最大传输次数和网络设备配置的重复次数传输Msg3，例如：HARQ最大传输次数为8，重复次数为64，终端设备每重复传输64次之后，网络设备向终端设配反馈确认信息，即使网络设备在第1次重复传输就接收到了Msg3，终端设备还是会继续重复传输传该Msg3，直到完成64次传输，这无疑造会浪费大量的传输资源。
发明内容
为了提高网络中传输资源的利用率，本申请实施例提供了一种数据传输的方法，以及相应的通信设备。
本申请实施例第一方面提供一种数据传输的方法，包括：终端设备从网络设备接收第一下行控制信息(downlink control information,DCI)，第一DCI用于指示终端设备在第一DCI指示的第一物理上行共享信道(physical uplinkshared channel，PUSCH)上传输第一Msg3，或者传输第二Msg3，其中，第一Msg3是随机接入过程中由随机接入响应消息调度的、且不携带用户数据的上行消息，第二Msg3是随机接入过程中由随机接入响应消息调度的、且携带用户数据的上行消息；终端设备根据第一DCI，在第一PUSCH上传输第一Msg3，或者传输第二Msg3；终端设备从网络设备接收第二DCI，第二DCI用于指示终端设备停止传输第一Msg3，或者停止传输第二Msg3；终端设备根据第二DCI，停止传输第一Msg3，或者停止传输第二Msg3。本申请实施例中的用户数据为用户面数据(user data)或非接入层(non-access stratum，NAS)消息。由该第一方面可见，终端设备在传输第一Msg3或第二Msg3的过程中，在没达到重复次数时，可以依据网络设备下发的DCI中的指示，停止传输第一Msg3或第二Msg3。从而避免了传输资源的浪费，提高了传输资源的利用率。
结合本申请第一方面，在第一种可能的实现方式中，第一DCI中用于指示传输第一Msg3 或第二Msg3的字段，以及第二DCI中用于指示停止传输第一Msg3或第二Msg3的字段为：第一DCI和第二DCI中标准已设置的、用于指示(new data indicator，NDI)的字段，或第一DCI和第二DCI中标准已设置的、用于指示HARQ进程号(HARQ process number)信息的字段，或所述第一DCI和所述第二DCI中新增的字段。对于标准已设置用于指示NDI的字段或用于指示HARQ进程号的字段来说，本申请实施例中的该标准可以是第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)标准36.212协议中R13及之后的版本。由该第一方面第二种可能的实现方式可见，因为在重传过程中使用不到HARQ进程号信息的字段和新数据指示NDI的字段，所以利用标准中已设置的HARQ进程号信息的字段或新数据指示NDI的字段来指示传输第一Msg3或第二Msg3，或者停止传输第一Msg3或第二Msg3，都可以在不额外增加指示字段的情况下实现数据传输的提前停止。
结合本申请第一方面或第一方面第一种，在第二种可能的实现方式中，该方法还包括：终端设备从网络设备接收第三DCI，第三DCI用于指示终端设备在第三DCI指示的第二PUSCH上传输第三Msg3，第三Msg3是随机接入过程中由随机接入响应消息调度的、且携带用户数据的上行消息；终端设备根据第三DCI，在第二PUSCH上传输第三Msg3；终端设备从网络设备接收第四DCI，第四DCI用于指示终端设备由传输第三Msg3回退为传输第四Msg3，其中，第四Msg3是随机接入过程中由随机接入响应消息调度的、且不携带用户数据的上行消息；终端设备根据第四DCI，在第四DCI所指示的PUSCH上传输第四Msg3。由第一方面第一种可能的实现方式可见，还可以在信道传输条件不好时，由传输带用户数据的第三Msg3回退到不带用户数据的第四Msg3，从而可以提高不带用户数据的第四Msg3的传输成功率。
结合本申请第一方面第二种可能的实现方式，在第三种可能的实现方式中，第三DCI中用于指示传输第三Msg3的字段，以及第四DCI中用于指示终端设备由传输第三Msg3回退为传输第四Msg3的字段为：第三DCI和第四DCI中标准已设置的、用于指示NDI的字段，或第三DCI和第四DCI中标准已设置的、用于指示HARQ进程号信息的字段，或所述第一DCI和所述第二DCI中新增的字段。由该第一方面第三种可能的实现方式可见，因为在重传过程中使用不到HARQ进程号信息的字段和新数据指示NDI的字段，所以利用标准中已设置的HARQ进程号信息的字段或新数据指示NDI的字段来指示传输第三Msg3或由传输第三Msg3回退到传输四Msg3，都可以在不额外增加指示字段的情况下实现回退。
结合上述第一方面，在第四种可能的实现方式中，该方法还包括：终端设备从网络设备接收第五DCI，第五DCI用于指示终端设备在第五DCI指示的第三PUSCH上传输第五Msg3，第五Msg3是随机接入过程中由随机接入响应消息调度的、且携带用户数据的上行消息；终端设备根据第五DCI中指示传输块大小信息的字段，在第三PUSCH上传输第五Msg3，第五DCI中指示传输块大小信息的字段所指示的传输块大小等于一个参数值，该参数值是随机接入响应RAR中指示的第五Msg3占用的传输块的大小；其中，RAR中指示的是第五Msg3，该参数值是第五Msg3占用的传输块的大小；终端设备从网络设备接收第六DCI；终端设备根据第六DCI中指示传输块大小信息的字段，由传输第五Msg3回退为在第六DCI所指示的PUSCH上传输第六Msg3，第六DCI中指示传输块大小信息的字段所指示的传输块大小小于 该参数值，第六Msg3是随机接入过程中由随机接入响应消息调度的、且不携带用户数据的上行消息。由该第一方面第四种可能的实现方式可见，在信道传输条件不好时，还可以通过传输块大小信息的字段来指示由传输带用户数据的第五Msg3回退到不带用户数据的第六Msg3，从而可以提高不带用户数据的第六Msg3的传输成功率。
结合上述第一方面，在第五种可能的实现方式中，该方法还包括：终端设备接收网络设备发送的无线资源控制RRC信令，RRC信令用于指示确定第二Msg3的混合自动重传HARQ最大传输次数；终端设备根据RRC信令确定第二Msg3的HARQ最大传输次数；终端设备根据第二Msg3的HARQ最大传输次数传输第二Msg3。该实现方式中只是以第二Msg3进行的说明，实际上其他携带用户数据的Msg3，如：第三Msg3和第五Msg3都可以采用该实现方式中的方案确定该Msg3的HARQ最大传输次数进行传输。由该第一方面第五种可能的实现方式可见，因为带用户数据的Msg3的传输块变大，所以需要提高带有用户数据的Msg3的HARQ最大传输次数，以避免丢包的情况频繁发生。
结合第一方面、第一方面第一种至第五种中任一可能的实现方式，在第六种可能的实现方式中，终端设备根据RRC信令确定第二Msg3的混合自动重传HARQ最大传输次数，包括：终端设备根据第一信息元素和第二信息元素确定第二Msg3的HARQ最大传输次数；或者，终端设备根据第三信息元素确定第二Msg3的HARQ最大传输次数；其中，第一信息元素是RRC信令中用于确定第二Msg3的HARQ最大传输次数的信息元素，第一信息元素用于指示第一集合中的一个值，第二信息元素是RRC信令中用于确定第一Msg3的HARQ最大传输次数的信息元素，第二信息元素用于指示第二集合中的一个值，第一集合与第二集合不同，第三信息元素是RRC信令中用于确定第二Msg3的HARQ最大传输次数的信息元素，所述第三信息元素用于指示第三集合中的一个值。其中第一集合可以为{1,2,4}，第二集合可以为{1,2,3,4,5,6,7,8}，第三集合比第二集合所包含的信息元素更多，例如：第三集合为{1,2,3,4,5,6,7,8,10,12,16,20,24,28}，或者第三集合为{1,2,3,4,5,6,7,8,10,12,16,20,24,28，spare1，spare2}，spare1和spare2为正整数，且spare1不等于spare2。。根据第一信息元素和第二信息元素确定第二Msg3的HARQ最大传输次数可以是从第一集合中选择数值4作为第一信息元素，从第二集合中选择数值8作为第二信息元素，然后将4与8的乘积作为第二Msg3的HARQ最大传输次数。由第一集合可见，只需要2个比特位就可以指示第一集合中的三个数值，通过第一集合中的数值与第二集合中的数值的乘积方式还可以确保第二Msg3的HARQ最大传输次数可达到32次。根据第三信息元素确定第二Msg3的HARQ最大传输次数例如可以是根据第三集合中的数值16确定第二Msg3的HARQ最大传输次数为16。当然，也可以是根据第三集合中的其他数值确定第二Msg3的HARQ最大传输次数。由该第六种可能的实现方式可见，第三集合大于第二集合不光是第三集合中所包含的信息元素多于第二集合中所包含的信息元素，而且第三集合中所包含的信息元素的最大值大于第二集合中所包含的信息元素的最大值。这种方式不需要乘积，只用一个集合就可以确保第二Msg3的HARQ最大传输次数可以取到较大值。所以该第一方面第六种可能的实现方式可以提升带数据的Msg3传输过程中的成功概率。
结合第一方面第六种可能的实现方式，在第七种可能的实现方式中，终端设备根据第 一信息元素和第二信息元素确定第二Msg3的HARQ最大传输次数，包括：终端设备根据第一信息元素确定第一值，根据第二信息元素确定第二值；终端设备将第一值和第二值的乘积作为第二Msg3的HARQ最大传输次数。由该第一方面第七种可能的实现方式可见，通过两个数值乘积的方式确定第二Msg3的HARQ最大传输次数，可以有效提高带数据的Msg3的HARQ最大传输次数，从而提高带数据的Msg3传输过程中的成功概率。
本申请第二方面提供一种数据传输的方法，包括：终端设备从网络设备接收第三DCI，第三DCI用于指示终端设备在第三DCI指示的第二PUSCH上传输第三Msg3，第三Msg3是随机接入过程中由随机接入响应消息调度的、且携带用户数据的上行消息；终端设备根据第三DCI，在第二PUSCH上传输第三Msg3；终端设备从网络设备接收第四DCI，第四DCI用于指示终端设备由传输第三Msg3回退为传输第四Msg3，其中，第四Msg3是随机接入过程中由随机接入响应消息调度的、且不携带用户数据的上行消息；终端设备根据第四DCI，在第四DCI所指示的PUSCH上传输第四Msg3。由该第二方面可见，还可以在信道传输条件不好时，由传输带用户数据的第三Msg3回退到不带用户数据的第四Msg3，从而可以提高不带用户数据的第四Msg3的传输成功率。
结合本申请第二方面，在第一种可能的实现方式中，第三DCI中用于指示传输第三Msg3的字段，以及第四DCI中用于指示终端设备由传输第三Msg3回退为传输第四Msg3的字段为：第三DCI和第四DCI中标准已设置的、用于指示NDI的字段，或第三DCI和第四DCI中标准已设置的、用于指示HARQ进程号信息的字段，或所述第一DCI和所述第二DCI中新增的字段。由该第二方面第一种可能的实现方式可见，因为在重传过程中使用不到HARQ进程号信息的字段和新数据指示NDI的字段，所以利用标准中已设置的HARQ进程号信息的字段或新数据指示NDI的字段来指示传输第三Msg3或由传输第三Msg3回退到传输四Msg3，都可以在不额外增加指示字段的情况下实现回退。
本申请第三方面提供一种数据传输的方法，包括：终端设备从网络设备接收第五DCI，第五DCI用于指示终端设备在第五DCI指示的第三PUSCH上传输第五Msg3，第五Msg3是随机接入过程中由随机接入响应消息调度的、且携带用户数据的上行消息；终端设备根据第五DCI中指示传输块大小信息的字段，在第三PUSCH上传输第五Msg3，第五DCI中指示传输块大小信息的字段所指示的传输块大小等于一个参数值，该参数值是随机接入响应RAR中指示的第五Msg3占用的传输块的大小；其中，RAR中指示的是第五Msg3，该参数值是第五Msg3占用的传输块的大小；终端设备从网络设备接收第六DCI；终端设备根据第六DCI中指示传输块大小信息的字段，由传输第五Msg3回退为在第六DCI所指示的PUSCH上传输第六Msg3，第六DCI中指示传输块大小信息的字段所指示的传输块大小小于该参数值，第六Msg3是随机接入过程中由随机接入响应消息调度的、且不携带用户数据的上行消息。由该第三方面可见，在信道传输条件不好时，还可以通过传输块大小信息的字段来指示由传输带用户数据的第五Msg3回退到不带用户数据的第六Msg3，从而可以提高不带用户数据的第六Msg3的传输成功率。
本申请第四方面提供一种数据传输的方法，包括：网络设备向终端设备发送第一下行控制信息DCI，第一DCI用于指示终端设备在第一DCI指示的第一物理上行共享信道PUSCH 上传输第一Msg3，或者传输第二Msg3，其中，第一Msg3是随机接入过程中由随机接入响应消息调度的、且不携带用户数据的上行消息，第二Msg3是随机接入过程中由随机接入响应消息调度的、且携带用户数据的上行消息；网络设备在第一PUSCH上接收终端设备传输的第一Msg3，或者第二Msg3；网络设备向终端设备发送第二DCI，第二DCI用于指示终端设备停止传输第一Msg3，或者停止传输第二Msg3。由该第四方面可见，终端设备在传输第一Msg3或第二Msg3的过程中，在没达到重复次数时，网络设备就已正确接收该第一Msg3或第二Msg3，则可以向终端设备下发的DCI，指示终端设备停止传输第一Msg3或第二Msg3。从而避免了传输资源的浪费，提高了传输资源的利用率。
结合第四方面，在第一种可能的实现方式中，第一DCI中用于指示传输第一Msg3或第二Msg3的字段，以及第二DCI中用于指示停止传输第一Msg3或第二Msg3的字段为：第一DCI和第二DCI中标准已设置的、用于指示NDI的字段，或第一DCI和第二DCI中标准已设置的、用于指示混合自动重传请求HARQ进程号信息的字段，或所述第一DCI和所述第二DCI中新增的字段。由该第四方面第二种可能的实现方式可见，因为在重传过程中使用不到HARQ进程号信息的字段和新数据指示NDI的字段，所以利用标准中已设置的HARQ进程号信息的字段或新数据指示NDI的字段来指示传输第一Msg3或第二Msg3，或者停止传输第一Msg3或第二Msg3，都可以在不额外增加指示字段的情况下实现数据传输的提前停止。
结合第四方面或第四方面第一种可能的实现方式，在第二种可能的实现方式中，该方法还包括：网络设备向终端设备发送第三DCI，第三DCI用于指示终端设备在第三DCI指示的第二PUSCH上传输第三Msg3，第三Msg3是随机接入过程中由随机接入响应消息调度的、且携带用户数据的上行消息；网络设备在第二PUSCH上接收终端设备传输的第三Msg3；网络设备向终端设备发送第四DCI，第四DCI用于指示终端设备由传输第三Msg3回退为传输第四Msg3，其中，第四Msg3是随机接入过程中由随机接入响应消息调度的、且不携带用户数据的上行消息。由第四方面第一种可能的实现方式可见，网络设备可以在信道传输条件不好时，指示终端设备由传输带用户数据的第三Msg3回退到不带用户数据的第四Msg3，从而可以提高不带用户数据的第四Msg3的传输成功率。

结合第五方面，在第一种可能的实现方式中，第三DCI中用于指示传输第三Msg3的字段，以及第四DCI中用于指示终端设备由传输第三Msg3回退为传输第四Msg3的字段为：第三DCI和第四DCI中标准已设置的、用于指示NDI的字段，或第三DCI和第四DCI中标准已设置的、用于指示混合自动重传请求HARQ进程号信息的字段，或所述第一DCI和所述第二DCI中新增的字段。由该第五方面第一种可能的实现方式可见，因为在重传过程中使用不到HARQ进程号信息的字段和新数据指示NDI的字段，所以利用标准中已设置的HARQ进程号信息的字段或新数据指示NDI的字段来指示传输第三Msg3或由传输第三Msg3回退到传输四Msg3，都可以在不额外增加指示字段的情况下实现回退。
本申请第六方面提供一种数据传输的方法，包括：网络设备向终端设备发送第五DCI，第五DCI用于指示终端设备在第五DCI指示的第三PUSCH上传输第五Msg3，第五Msg3是随机接入过程中由随机接入响应消息调度的、且携带用户数据的上行消息；网络设备在第三PUSCH上接收终端设备根据第五DCI中指示传输块大小信息的字段传输的第五Msg3，第五DCI中指示传输块大小信息的字段所指示的传输块大小等于一个参数值，该参数值是随机接入响应RAR中指示的第五Msg3占用的传输块的大小；网络设备向终端设备发送第六DCI；网络设备在第六DCI所指示的PUSCH上传输上接收第六Msg3，第六DCI中指示传输块大小信息的字段所指示的传输块大小小于该参数值，第六Msg3是随机接入过程中由随机接入响应消息调度的、且不携带用户数据的上行消息。由该第六方面可见，网络设备在信道传输条件不好时，还可以通过传输块大小信息的字段来指示终端设备由传输带用户数据的第五Msg3回退到不带用户数据的第六Msg3，从而可以提高不带用户数据的第六Msg3的传输成功率。

图1为本申请实施例中通信系统的一实施例示意图。
如图1所示，该通信系统包括网络设备和终端设备。
本申请实施例中，所述网络设备是一种部署在无线接入网中为终端设备提供无线通信功能的装置。所述网络设备可以包括各种形式的宏基站，微基站(也称为小站)，中继站，接入点等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如，在LTE系统中，称为演进的节点B(evolved NodeB，eNB或者eNodeB),在第三代(3rd Generation，3G)系统中，称为节点B(Node B)，在第五代(3rd Generation，5G)系统中成为无线网络接入设备等。为方便描述，本申请所有实施例中，上述为终端提供无线通信功能的装置统称为网络设备或基站或BS。
本申请实施例中所涉及到的终端设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。所述终端可以是移动站(Mobile Station，MS)、用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(Personal Digital Assistant， 简称：PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handset)、膝上型电脑(laptop computer)、机器类型通信(Machine Type Communication,MTC)终端等。
图1的通信系统包括基站(Base station)和用户设备(user equipment)UE1至UE6，在该通信系统中，Base station发送调度消息给UE1～UE6中的一个或多个。此外，UE4、UE5和UE6三个用户设备也可以组成一个通信系统，在该通信系统中，UE5可以发送调度信息给UE4和UE6中的一个或两个，这时UE5就充当基站的功能。
图1所示的通信系统还可以用另一种形式来表示，如图2所示，通信系统包括终端设备10和网络设备20，其中，终端设备10包括处理器101、存储器102和收发器103，收发器103包括发射机1031、接收机1032和天线1033。接收机1032可以用于通过天线1033接收网络设备20发送的各种DCI，发射机1031可以用于通过天线1033向网络设备20发送各种Msg3。网络设备20包括处理器201、存储器202和收发器203，收发器203包括发射机2031、接收机2032和天线2033。发射机2031可以用于通过天线2033向终端设备10发送各种DCI，接收机2032可以用于通过天线2033接收终端设备10发送的各种Msg3。
以上介绍了通信系统、终端设备以及网络设备的结构，下面介绍终端设备和网络设备之间的数据传输过程。
如图3所示，本申请实施例提供的数据传输的方法的一实施例包括：
301、网络设备向终端设备发送第一DCI。
所述第一DCI用于指示所述终端设备在所述第一DCI指示的第一物理上行共享信道PUSCH上传输第一Msg3，或者传输第二Msg3，其中，所述第一Msg3是随机接入过程中由随机接入响应消息调度的、且不携带用户数据的上行消息，所述第二Msg3是随机接入过程中由随机接入响应消息调度的、且携带用户数据的上行消息。本申请实施例中的用户数据为用户面数据(user data)或非接入层(non-access stratum，NAS)消息。
302、终端设备接收到第一DCI后，根据所述第一DCI，在第一PUSCH上传输所述第一Msg3，或者传输第二Msg3。
303、网络设备向终端设备发送第二DCI。
所述第二DCI用于指示所述终端设备停止传输第一Msg3，或者停止传输第二Msg3。
需要说明的是，若在第一PUSCH上传输的是第一Msg3，则第二DCI指示停止传输第一Msg3。若在第一PUSCH上传输的是第二Msg3，则第二DCI指示停止传输第二Msg3。
304、终端设备接收到第二DCI后，根据所述第二DCI，停止传输第一Msg3，或者停止传输第二Msg3。
若在第一PUSCH上传输的是第一Msg3，则终端设备停止传输第一Msg3。若在第一PUSCH上传输的是第二Msg3，则终端设备停止传输第二Msg3。
由以上图3所对应的数据传输的方法的实施例可见，终端设备在传输第一Msg3或第二Msg3的过程中，在没达到重复次数时，网络设备就已正确接收该第一Msg3或第二Msg3，则可以向终端设备下发的DCI，指示终端设备停止传输第一Msg3或第二Msg3。从而避免了传输资源的浪费，提高了传输资源的利用率。
可选地，其中第一DCI中用于指示传输第一Msg3或第二Msg3的字段，以及第二DCI 中用于指示停止传输第一Msg3或第二Msg3的字段为：第一DCI和第二DCI中标准已设置的、用于指示NDI的字段，或第一DCI和第二DCI中标准已设置的、用于指示HARQ进程号信息的字段，或所述第一DCI和所述第二DCI中新增的字段。
DCI有DCI Format 6-0A和DCI Format 6-0B两种格式，这两种格式中都包括HARQ进程号字段和NDI字段。在DCI Format 6-0A中，HARQ进程号字段为3bits，NDI字段为1bit。在DCI Format 6-0B中，HARQ进程号字段为1bit，NDI字段为1bit。
随机接入过程中，Msg3的传输只用1个HARQ进程，所以不需要指示HARQ进程号。
Msg3的HARQ重传和重复传输过程中不会有新的数据传输，所以该字段不用。
所以可以利用HARQ进程号字段或NDI字段来指示传输第一Msg3或第二Msg3，或者停止传输第一Msg3或第二Msg3。例如：若第一PUSCH上传输的是第一Msg3，HARQ进程号字段或NDI字段的指示为0时，可以用于指示传输第一Msg3，HARQ进程号字段或NDI字段的指示为1时，可以用于指示停止传输第一Msg3。若第一PUSCH上传输的是第二Msg3，HARQ进程号字段或NDI字段的指示为0时，可以用于指示传输第二Msg3，HARQ进程号字段或NDI字段的指示为1时，可以用于指示停止传输第二Msg3。当然，此处只是以0和1为例进行说明，不应理解为是对0/1以及对应指示功能的限定。实际上HARQ进程号字段或NDI字段的指示也可以是其他数值，也可以不是数值，例如也可以用T/F来指示，或者用其他形式来指示传输或停止传输。
由该可选实施例可见，因为在重传过程中使用不到HARQ进程号信息的字段和NDI的字段，所以利用标准中已设置的HARQ进程号信息的字段或新数据指示NDI的字段来指示传输第一Msg3或第二Msg3，或者停止传输第一Msg3或第二Msg3，都可以在不额外增加指示字段的情况下实现数据传输的提前停止。
如图4所示，本申请实施例提供的数据传输的方法的另一实施例包括：
401、网络设备向终端设备发送第三DCI。
所述第三DCI用于指示所述终端设备在所述第三DCI指示的第二PUSCH上传输第三Msg3，所述第三Msg3是随机接入过程中由随机接入响应消息调度的、且携带用户数据的上行消息。
402、终端设备接收到第三DCI后，根据所述第三DCI，在所述第二PUSCH上传输所述第三Msg3。
403、网络设备向终端设备发送第四DCI。
所述第四DCI用于指示所述终端设备由传输所述第三Msg3回退为传输第四Msg3，其中，所述第四Msg3是随机接入过程中由随机接入响应消息调度的、且不携带用户数据的上行消息。
404、终端设备接收到第四DCI后，根据所述第四DCI，在所述第四DCI所指示的PUSCH上传输所述第四Msg3。
由上述图4所对应的实施例可见，网络设备可以在信道传输条件不好时，可以指示终端设备由传输带用户数据的第三Msg3回退到不带用户数据的第四Msg3，从而可以提高不带用户数据的第四Msg3的传输成功率。而且，在回退到第四Msg3后，若终端设备接收到 停止传输该第四Msg3的DCI，终端设备即可停止对该第四Msg3的传输。
需要说明的是，图4对应的实施例可以独立于图3所对应的实施例，也可以是在图3所对应实施例基础上的进一步可选实施例。
可选地，在上述图3对应的实施例或其可选实施例，或者图4对应的实施例的基础上，进一步可选地的实施例还可以包括：
第三DCI中用于指示传输第三Msg3的字段，以及第四DCI中用于指示终端设备由传输第三Msg3回退为传输第四Msg3的字段为：第三DCI和第四DCI中标准已设置的、用于指示NDI的字段，或第三DCI和第四DCI中标准已设置的、用于指示HARQ进程号信息的字段，或所述第一DCI和所述第二DCI中新增的字段。
参阅上述对DCI格式以及HARQ进程号字段和NDI字段的介绍，所以可以利用HARQ进程号字段或NDI字段来指示由传输第三Msg3回退到传输第四Msg3。例如：若第二PUSCH上传输的是第三Msg3，HARQ进程号字段或NDI字段的指示为0时，表示不回退，继续传输第三Msg3。HARQ进程号字段或NDI字段的指示为1时，表示回退，由传输第三Msg3改成传输第四Msg3。当然，此处只是以0和1为例进行说明，不应理解为是对0/1以及对应指示功能的限定。实际上HARQ进程号字段或NDI字段的指示也可以是其他数值，也可以不是数值，例如也可以用T/F来指示，或者用其他形式来指示是否回退。
当DCI的格式为Format 6-0A时，HARQ进程号字段为3bits，还可以是用3bits中的一个比特位表示传输上述图3所对应实施例中的第一Msg3或第二Msg3，或停止传输第一Msg3或第二Msg3，用另外两个比特位中的一个比特位表示继续传输第三Msg3或者回退到第四Msg3。还可以是3bits可以表示8种不同的取值，选取其中4个取值分别表示传输、停止传输、继续传输和回退四种指示状态。例如：8种状态可以用0至7这8个数值表示，用0指示传输上述图3所对应实施例中的第一Msg3或第二Msg3，用1指示停止传输第一Msg3或第二Msg3，用2指示图4对应实施例中的继续传输第三Msg3，用3指示回退到第四Msg3。
由该可选实施例可见，因为在重传过程中使用不到HARQ进程号信息的字段和新数据指示NDI的字段，所以利用标准中已设置的HARQ进程号信息的字段或新数据指示NDI的字段来指示传输第三Msg3或由传输第三Msg3回退到传输四Msg3，都可以在不额外增加指示字段的情况下实现回退。
如图5所示，本申请实施例提供的数据传输的方法的另一实施例包括：
501、网络设备向终端设备发送第五DCI。
所述第五DCI用于指示所述终端设备在所述第五DCI指示的第三PUSCH上传输第五Msg3，所述第五Msg3是随机接入过程中由随机接入响应消息调度的、且携带用户数据的上行消息。
502、终端设备接收到第五DCI后，根据所述第五DCI中指示传输块大小信息的字段，在所述第三PUSCH上传输所述第五Msg3。
所述第五DCI中指示传输块大小信息的字段所指示的传输块大小等于一个参数值，所述参数值是随机接入响应RAR中指示的所述第五Msg3占用的传输块的大小。
503、网络设备向终端设备发送第六DCI。
504、终端设备接收到第六DCI后，根据所述第六DCI中指示传输块大小信息的字段，由传输所述第五Msg3回退为在所述第六DCI所指示的PUSCH上传输第六Msg3。
所述第六DCI中指示传输块大小信息的字段所指示的传输块大小小于所述参数值，所述第六Msg3是随机接入过程中由随机接入响应消息调度的、且不携带用户数据的上行消息。
需要说明的是，每个带用户数据的Msg3的传输块大小是固定的，其大小等于一个参数值。不带用于数据的Msg3的传输块大小小于带用户数据的Msg3的传输块大小，所以在第六DCI中指示传输块大小信息的字段所指示的传输块大小小于所述参数值，则表示需要进行回退，由带用户数据的Msg3回退带用户数据的Msg3。
由该图5对应的实施例可见，网络设备在信道传输条件不好时，还可以通过传输块大小信息的字段来指示终端设备由传输带用户数据的第五Msg3回退到不带用户数据的第六Msg3，从而可以提高不带用户数据的第六Msg3的传输成功率。
需要说明的是，本申请实施例中虽然涉及了第一Msg3、第二Msg3、第三Msg3、第四Msg3、第五Msg3和第六Msg3。但仅是为了方便上下文的表述，实际上Msg3只有两种，一种是不带用户数据的Msg3，一种是带用户数据的Msg3。
该图5对应的实施例可以独立于上述各实施例，也可以是图3及其可选实施例基础上的进一步可选实施例。
可选地，在上述任一实施例或可选实施例的基础上，本申请实施例提供的数据传输的方法的实施例还包括：
所述终端设备接收所述网络设备发送的无线资源控制RRC信令，所述RRC信令用于指示确定所述第二Msg3的混合自动重传HARQ最大传输次数；
所述终端设备根据所述RRC信令确定所述第二Msg3的HARQ最大传输次数；
所述在所述第一PUSCH上传输所述第二Msg3，可以包括：
所述终端设备根据所述第二Msg3的HARQ最大传输次数传输所述第二Msg3。
本处只是以第二Msg3进行的说明，实际上其他带用户数据的Msg3，如：第三Msg3和第五Msg3都可以采用该实现方式中的方案确定该Msg3的HARQ最大传输次数进行传输。
第一Msg3的HARQ最大传输次数可以通过一个RRC信令来通知，第二Msg3的HARQ最大传输次数可以通过另一个RRC信令来通知。
因为带用户数据的Msg3的传输块变大，所以需要提高带有用户数据的Msg3的HARQ最大传输次数，以避免丢包的情况频繁发生。
其中，可选地，所述终端设备根据RRC信令确定所述第二Msg3的混合自动重传HARQ最大传输次数，可以包括：
终端设备根据第一信息元素和第二信息元素确定第二Msg3的HARQ最大传输次数；或者，
终端设备根据第三信息元素确定第二Msg3的HARQ最大传输次数；
其中，第一信息元素是RRC信令中用于确定第二Msg3的HARQ最大传输次数的信息元 素，第一信息元素用于指示第一集合中的一个值，第二信息元素是RRC信令中用于确定第一Msg3的HARQ最大传输次数的信息元素，第二信息元素用于指示第二集合中的一个值，第一集合与第二集合不同，第三信息元素是RRC信令中用于确定第二Msg3的HARQ最大传输次数的信息元素，所述第三信息元素用于指示第三集合中的一个值。其中第一集合可以为{1,2,4}，第二集合可以为{1,2,3,4,5,6,7,8}，第三集合比第二集合所包含的信息元素更多，例如：第三集合为{1,2,3,4,5,6,7,8,10,12,16,20,24,28}，或者第三集合为{1,2,3,4,5,6,7,8,10,12,16,20,24,28，spare1，spare2}，spare1和spare2为正整数，且spare1不等于spare2。。根据第一信息元素和第二信息元素确定第二Msg3的HARQ最大传输次数可以是从第一集合中选择数值4作为第一信息元素，从第二集合中选择数值8作为第二信息元素，然后将4与8的乘积作为第二Msg3的HARQ最大传输次数。由第一集合可见，只需要2个比特位就可以指示第一集合中的三个数值，通过第一集合中的数值与第二集合中的数值的乘积方式还可以确保第二Msg3的HARQ最大传输次数可达到32次。根据第三信息元素确定第二Msg3的HARQ最大传输次数例如可以是根据第三集合中的数值16确定第二Msg3的HARQ最大传输次数为16。当然，也可以是根据第三集合中的其他数值确定第二Msg3的HARQ最大传输次数。由该第六种可能的实现方式可见，第三集合大于第二集合不光是第三集合中所包含的信息元素多于第二集合中所包含的信息元素，而且第三集合中所包含的信息元素的最大值大于第二集合中所包含的信息元素的最大值。这种方式不需要乘积，只用一个集合就可以确保第二Msg3的HARQ最大传输次数可以取到较大值。所以该实施例可以提升带数据的Msg3传输过程中的成功概率。
其中，可选地，所述终端设备根据所述第一信息元素和第二信息元素确定所述第二Msg3的HARQ最大传输次数，可以包括：
所述终端设备根据所述第一信息元素确定第一值，根据所述第二信息元素确定第二值；
所述终端设备将所述第一值和所述第二值的乘积作为所述第二Msg3的HARQ最大传输次数。
例如：参考上面示例RRC信令中调度了第一集合中的第一值为4，调度了第二集合中的第二值为8，则可以确定第二Msg3的HARQ最大传输次数为4×8＝32次。
由该实施例可见，通过两个数值乘积的方式确定第二Msg3的HARQ最大传输次数，可以有效提高带数据的Msg3的HARQ最大传输次数，从而提升带数据的Msg3传输过程中的成功概率。
以上多个数据传输的方法实施例中描述了数据提前停止，数据回退以及确定带数据的Msg3的HARQ最大传输次数的方案，下面结合附图描述本申请实施例中的通信设备。本申请实施例中的通信设备可以包括终端设备、网络设备和芯片系统，在不同角色下其功能不同。
如图6所示，本申请实施例提供的通信设备包括终端设备或芯片系统，该通信设备60包括：
接收单元601，用于从网络设备接收第一下行控制信息DCI，所述第一DCI用于指示所述终端设备在所述第一DCI指示的第一物理上行共享信道PUSCH上传输第一消息Msg3，或 者传输第二Msg3，其中，所述第一Msg3是随机接入过程中由随机接入响应消息调度的、且不携带用户数据的上行消息，所述第二Msg3是随机接入过程中由随机接入响应消息调度的、且携带用户数据的上行消息；
处理单元602，用于根据所述接收单元601接收的所述第一DCI，确定在所述第一PUSCH上传输所述第一Msg3，或者传输所述第二Msg3；
