具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
应理解，本公开实施例的技术方案可以应用于各种通信系统，例如：长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)或全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、5G系统，或者说新无线(New Radio，NR)系统，或者为后续演进通信系统。
在本公开实施例中，终端设备可以包括但不限于移动台(Mobile Station，MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、用户设备(User Equipment，UE)、手机(handset)及便携设备(portable equipment)、车辆(vehicle)等，该终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，终端设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
如图1所示，本公开的一个实施例提供一种数据传输方法100，该方法可 以由终端设备执行，包括如下步骤：
S102：若在通过第一上行授权(UL grant)对应的混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)进程传输第一数据之前，接收到第二上行授权，则通过目标上行授权所对应的HARQ进程传输目标数据。
其中，上述目标上行授权为第一上行授权和第二上行授权中的一个；上述目标数据为第一数据和第二数据中的一个。
本公开实施例中，第一上行授权用于调度所述第一数据的传输，第一数据包括随机接入过程中的数据。如前所述，随机接入包括4-step RACH和2-step RACH，可选地，第一数据具体可以是4-step RACH中的Msg3；或者是2-step RACH中的MsgA中的上行数据。
本公开各个实施例中提到的MsgA，具体可以是2-step RACH中终端设备向网络设备发送的随机接入消息；本公开后续各个实施例中提到的MsgB，具体可以是2-step RACH中网络设备向终端设备发送的随机接入响应消息。
本公开实施例中，第二上行授权是终端设备在上述随机接入过程中接收到，第二上行授权用于调度第一数据之外的数据传输，第一数据之外的数据包括上述第二数据。具体地，第二上行授权可以用于调度第二数据传输，上述第二数据可以是高优先级的数据、也可以是低优先级的数据等等。
可选地，上述第一上行授权对应的HARQ进程和所述第二上行授权对应的HARQ进程相同。
在一个例子中，上述目标上行授权为第一上行授权，目标数据是第一数据，这样，S102可以是通过第一上行授权对应的HARQ进程传输第一数据，该例子中，第二上行授权的优先级低于第一上行授权的优先级，或者是，第二上行授权调度的数据的优先级低于第一数据，第一数据是由第一上行授权调度。在该例子中，由于第一数据包括随机接入过程中的数据，S102通过第一上行授权对应的HARQ进程传输第一数据，通过忽略第二上行授权，不会影响到随机接入过程的顺利执行。
在另一个例子中，上述目标上行授权为第二上行授权，目标数据是第二数据，这样，S102可以是通过第二上行授权对应的HARQ进程传输第二数据。该例子中，具体可以是第二上行授权的优先级高于第一上行授权的优先 级。
本公开实施例提供的数据传输方法，终端设备在随机接入过程中，若在通过第一上行授权对应的HARQ进程传输第一数据之前，接收到第二上行授权，则通过第一上行授权对应的HARQ进程传输第一数据，或通过第二上行授权对应的HARQ进程传输第二数据，解决了终端设备无法确定该如何处理接收到的上行授权的问题，同时解决了因第一上行授权和第二上行授权对应的HARQ进程相同而造成不必要的HARQ缓存数据丢失的问题，从而保证数据传输的可靠性和有效性。
可选地，作为一个实施例，在上述实施例100的S102之前还可以包括如下步骤：接收上述第一上行授权，将第一上行授权和第一上行授权对应的HARQ信息递交给HARQ实体。具体应用中，若在接收到第一上行授权之后，且在发送第一数据之前，接收到第二上行授权，则通过目标上行授权所对应的HARQ进行传输目标数据。

可选地，该实施例中，在不满足上述第一预设条件的情况下，目标上行授权是第二上行授权，终端设备即可通过第二上行授权对应的HARQ进程传输第二数据。

2)第二上行授权对应的下行控制信息(Downlink Control Information，DCI)中包括指示信息，所述指示信息指示所述第二上行授权的优先级低于所述第一上行授权的优先级。
可选地，作为一个实施例，在实施例100的S102中通过目标上行授权所对应的HARQ进程传输目标数据之前，还可以包括如下步骤：在满足第二预设条件的情况下，启动或重启动与所述第一上行授权对应的HARQ进程相关联的定时器。
该实施例能够在第一上行授权对应的HARQ进程相关联的定时器运行期间，确定出目标UL grant是第一UL grant或第二UL grant，因增加了定时器这一限制条件，提高了该实施例执行操作的可靠性。
其中，第二预设条件包括以下至少一种：
1)接收到所述第一上行授权；
2)从复用和组装实体中得到所述第一数据；
3)所述第一数据被存放在Msg3缓存中；

1)在该定时器运行期间，若满足第一预设条件，则目标上行授权是第一上行授权；其中，该实施例还可以忽略所述第二上行授权。上述第一预设条件包括：所述第二上行授权的优先级低于所述第一上行授权的优先级。
可选地，该实施例中，终端设备通过第一上行授权对应的HARQ进程传输第一数据之前，还可以停止上述目标定时器。
