具体实施方式
为了便于理解，首先介绍本申请涉及的术语。
1、带宽部分(Bandwidth Part，BWP)
终端设备在进行数据收发的时候，网络设备会指定终端设备工作的频率范围，也就是BWP。
为了更好的理解本申请实施例公开的一种BWP的同步方法，下面首先对本申请实施例适用的通信系统进行描述。
请参见图1，图1为本申请实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于 一个网络设备和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本申请实施例的限定，实际应用中可以包括两个或两个以上的网络设备，两个或两个以上的终端设备。图1所示的通信系统以包括一个网络设备101和一个终端设备102为例。

下面结合附图对本申请所提供的BWP的同步方法及其装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种确定BWP的同步方法的流程示意图。如图2所示，该方法由终端设备执行，可以包括但不限于如下步骤：
S201，确定两个及两个以上的上行接入过程被配置的带宽部分BWP。
可选地，上行接入过程包括以下几种：小数据传输(Small Data Transmission，SDT)过程；随机接入(Random Access Channel，RACH)SDT过程；配置授权(Configure Grant，CG)SDT过程；非SDT上行接入过程。本申请中，两个及两个上行接入过程为上述上行接入过程中任意两个或两个以上的组合。
作为一种可能的实现方式，可以基于协议约定两个及两个以上的上行接入过程的BWP。
作为另一种可能的实现方式，可以由网络设备配置两个及两个以上的上行接入过程的BWP。可选地，网络设备向终端设备发送配置信息，该配置信息中携带两个及两个以上的上行接入过程的BWP。可选地，网络设备可以通过不同的配置信息，分别配置两个及两个以上的上行接入过程的BWP。
以配置CG SDT过程的BWP为例进行说明，网络设备通过无线资源控制释放(Radio Resource Control Release，RRCRelease)消息给终端设备配置小区1的CG SDT过程的CG资源，并给该CG资源配置了BWP1。相应地，终端设备可以从RRCRelease消息中确定出CG SDT过程的CG资源和CG资源对应的BWP1，也就是说为该CG SDT过程配置BWP1。
需要说明的是，空闲态或者去激活态下的终端设备，在网络设备配置的初始(initial)BWP上工作，例如执行连接建立或连接恢复过程；对于激活状态下的终端设备，网络设备可以为终端设备配置两个及两个以上的上行接入过程各自的BWP。
可选地，每个上行接入过程被配置有BWP，不同的上行接入过程可以配置有不同的BWP。
可选地，BWP包括上行BWP指示信息和下行BWP指示信息中的至少一项，BWP指示信息包括BWP标识和BWP类型指示中的至少一项。
可选地，网络设备为终端设备配置BWP时，可以通过协议约定BWP的初始状态，例如基于协议约定确定每个上行接入过程所被配置的BWP的初始状态。
可选地，网络设备为终端设备配置BWP时，可以通过网络设备指示该BWP的初始状态，例如网络设备向终端设备发送的状态指示信息，状态指示信息用于指示被配置的BWP的初始状态。其中，BWP的初始状态为激活态、去激活态和休眠态中的一种。
S202，确定执行第一上行接入过程，则激活第一上行接入过程对应的第一BWP，其中，第一上行接入过程为两个及两个以上的上行接入过程中的任意一个。
本申请实施例中，将终端设备执行的上行接入过程称为第一上行接入过程。
在一些实现中，确认终端设备执行的第一上行接入过程为SDT过程，则激活SDT过程对应的第一BWP。
在一些实现中，确认终端设备执行的第一上行接入过程为RACH SDT过程，则激活RACH SDT过程对应的第一BWP。
在一些实现中，确认终端设备执行的第一上行接入过程为CG SDT过程，则激活CG SDT过程对应的第一BWP。
在一些实现中，确认终端设备执行的第一上行接入过程为非SDT上行接入过程，则激活非SDT上行接入过程对应的第一BWP。
例如，网络设备给小区1的CG SDT过程的CG资源配置了BWP-1，终端设备当前在小区1驻留，终端设备驻留的BWP为initial BWP，也就是说，终端当前激活的BWP为initial BWP。响应于终端在小区1触发SDT过程，并且执行了CG SDT过程，由于BWP-1不是当前激活的BWP，则终端设备将BWP-1激活。
在一些实现中，确定终端设备处于空闲态或去激活态，在指定BWP上对终端设备驻留小区进行小区测量，其中，指定BWP包括初始BWP、当前激活BWP和协议约定BWP中的一个。
本申请实施例中，为了使网络设备和终端设备对于终端设备当前工作的BWP频域资源的理解一致，为终端设备确定两个及两个以上的上行接入过程被配置的BWP，其中两个及两个以上的上行接入过程中的任意一个可以作为第一上行接入过程，当终端设备执行第一上行接入过程的情况下，激活第一上行接入过程对应的第一BWP。通过实施本申请实施例，可以使终端设备根据执行的上行接入过程确认激活对应的BWP。通过这种方式，可以让网络设备和终端设备对于终端设备使用的BWP频域资源的理解保持一致，从而避免信号发送丢失。
本申请实施例提供的BWP的同步方法还包括以下步骤：
可选地，本申请实施例中，确定终端设备执行第一上行接入过程后，还需将执行第一上行接入过程之前处于激活状态的BWP去激活。例如，第一上行接入过程为SDT过程，终端设备在执行SDT过程之前，处于RACH SDT过程，当执行了SDT过程后，需要集合SDT过程对应的第一BWP，进一步地，将RACH SDT过程所对应的BWP去激活。本申请中可以避免同时存在两个激活的BWP的情况，避免频域资源的浪费以及信号发送容易丢失的问题。
请参见图3，图3是本申请实施例提供的一种BWP的同步方法的流程示意图。如图3所示，该方法由终端设备执行，可以包括但不限于如下步骤：
S301，确定两个及两个以上的上行接入过程被配置的带宽部分BWP。
S302，确定执行第一上行接入过程，则激活第一上行接入过程对应的第一BWP，其中，第一上行接入过程为两个及两个以上的上行接入过程中的任意一个。
步骤S301、步骤S302的相关内容可以参见上述实施例的相关介绍，此处不再赘述。
S303，接收网络设备发送的去激活指示，其中，去激活指示用于指示终端设备将当前激活的第一BWP去激活。
在一些实现中，需要将终端设备当前激活的BWP去激活时，网络设备向终端设备发送去激活指示，其中，去激活指示用于指示终端设备将当前激活的BWP去激活。
本申请实施例中，当前激活的BWP为当前终端设备所执行的上行接入过程被配置的BWP。
S304，激活网络设备配置或协议约定的第三BWP。
终端设备在对第一BWP去激活后，为了与网络设备继续进行通信还需要激活第三BWP。可选地，第三BWP可以根据协议约定，例如，第三BWP可以为initial BWP。可选地，第三BWP也可以由网络设备配置给终端设备。例如，网络设备向终端设备配置第三BWP为initial BWP。本申请中，在第三BWP为initial BWP的情况下，终端设备可以激活initial BWP。
在一些实现中，终端设备在BWP-1进行CG SDT过程，终端设备接收到网络设备发送的去激活指示，则终端设备将当前激活的BWP-1去激活。若网络设备配置或协议约定的第三BWP为initial BWP，则终端设备可以激活initial BWP。
在一些实现中，终端设备在initial BWP-2进行随机接入过程，终端设备接收到网络设备发送的去激活指示，则终端设备将当前激活的initial BWP-2去激活，并根据协议约定将initial BWP-1激活。若网络设备配置或协议约定的第三BWP为initial BWP，则终端设备可以激活initial BWP。
通过实施本申请实施例，可以使终端设备根据执行的上行接入过程确认激活对应的BWP。通过这种方式，可以让网络设备和终端设备对于终端设备使用的BWP频域资源的理解保持一致，从而避免信号发送丢失。

S403，确定终端设备从第一上行接入过程切换至第二上行接入过程，则激活第二上行接入过程对应 的第二BWP，和/或去激活第一BWP。
在一些实现中，终端设备应用的业务发生变化时，上行接入过程会发生变化，终端设备从第一上行接入过程切换至第二上行接入过程。
需要说明的是，第一上行接入过程对应的BWP称为第一BWP，第二上行接入过程的BWP称为第二BWP。
在一些实现中，第一上行接入过程切换至第二上行接入过程，则激活第二上行接入过程对应的第二BWP。
在一些实现中，第一上行接入过程切换至第二上行接入过程，则去激活第一BWP。
在一些实现中，第一上行接入过程切换至第二上行接入过程，则激活第二上行接入过程对应的第二BWP，且去激活第一BWP。
可选地，第一BWP和所述第二BWP有重叠。可选地，第一BWP包括第二BWP，例如，第二BWP的频率范围为2.4GHz-2.5GHz，则第一BWP的频率范围在2.43GHz-2.48GHz。
通过实施本申请实施例，可以使终端设备根据执行的上行接入过程确认激活对应的BWP。终端设备应用的业务发生变化时，切换上行接入过程后，也可以保持BWP的同步调整。通过这种方式，可以让网络设备和终端设备对于终端设备使用的BWP频域资源的理解保持一致，从而避免信号发送丢失。

在一些实现中，响应于监控到第一上行接入过程的测量结果不再满足选择第一上行接入过程的测量门限值，则确定监听到切换触发事件。
在一些实现中，响应于监控到第一上行接入过程的上行发送失败次数达到门限值，则确定监听到切换触发事件。
监听到切换触发事件后，终端设备进一步确定从第一上行接入过程切换至第二上行接入过程。
