具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
在LTE系统中，终端可支持最大20MHz的系统带宽。在新无线(NR，New Radio)系统中，一部分终端设备可能并不一定支持全部频率范围的系统带宽。因此，若假设在某一时间点，终端只支持一个激活的BWP，则需要控制终端设备进行BWP的切换。
实施例一、
本发明实施例提供了一种切换带宽部分(BWP)的方法，应用于终端设备，如图1所示，包括：
步骤101：获取定时器；
步骤102：基于所述定时器，确定是否从当前激活的第一带宽部分BWP切换到第二BWP；其中，所述第一BWP与第二BWP不同。
这里，所述BWP主要包含三个参数：Numerology：标示基础参数集，标示载波间隔SCS；中心频点；带宽：小于或者等于最大系统带宽。
由此可以看出，BWP是一个频域维度的概念。同时，现有的讨论假设在一个时间点，终端只支持一个激活的BWP。所谓激活，是指终端期望在该BWP规定的带宽上接收信号，包括数据传输(上下行)，系统消息等等。
前述步骤101中，所述获取定时器，可以为终端设备本身默认的定时器，或者，可以为用户为终端设备配置的定时器；当然，还可以包括：获取网络侧为所述终端设备配置的所述定时器。
其中，所述网络侧为终端设备配置定时器，可以为当确定终端设备仅支持部分带宽，或者确定终端设备采用BWP进行通信的时候，网络侧为终端设备配置定时器。另外，网络侧为不同终端设备所配置的定时器可以相同也可以不同；网络侧可以基于终端设备所要进行的业务类型进行确定，比如，当终端设备需要执行的业务为传输速率较快、或者业务的传输数据较多的，可以配置宽的BWP；关于业务类型的确定可以基于QoS等参数。需要理解的是，还可以存在其他的确定BWP的方式，本实施例不进行穷举。
所述定时器的作用包括用于在其开启之后，结束之时，确定执行从当前激活的第一带宽部分BWP切换到第二BWP的操作；也就是说，终端根据配置的定时器来决定是否从当前激活的带宽部分(BWP)切换到另外一个配置的带宽部分。
另外，执行步骤102之前，本实施例提供的方法还包括：判断是否开启所述定时器。
判断是否开启定时器的方法，还可以包括以下之一：
当终端设备传输物理上行共享信道(PUSCH，Physical Uplink Shared  Channel)时，开启所述定时器；
传输无线资源控制(RRC，Radio Resource Control)信令时，开启所述定时器；
当终端设备发起随机接入成功时，开启所述定时器；
当接收到下行控制信息，且通过下行控制信息调度上下行传输的时候，开启所述定时器；所述下行控制信息，可以为DCI；
当终端设备在网络侧为其配置的资源上发送或接收数据的时候，开启所述定时器。
前述步骤102中，所述基于所述定时器，确定是否从当前激活的第一带宽部分BWP切换到第二BWP，包括：当所述定时器失效时，确定从当前激活的第一BWP切换到第二BWP。其中，所述定时器失效可以为所述定时器的定时结束。第二BWP也可以为网络侧为终端设备配置的BWP；第二BWP与第一BWP可以相同也可以不同，比如，可以相同频点并且宽度相同，当然也可以为不同频点、宽度相同，或者相同频点宽度不同，或者频点以及宽度均不相同的BWP，或者还可以为相同频点相同带宽，但是BWP对应不同的基础参数集(numerology)。
也就是说，当终端设备采用BWP传输业务的时候，如果在较长的时间内没有进行业务数据的发送或接收，则可能会造成资源上的浪费，因此，通过采用本实施例提供的方案，能够增加针对BWP的定时器，使得定时器失效也就是定时器结束的时候，进行BWP的切换。比如，当第一BWP的带宽较大的时候，若长时间没有业务数据的传输，就会造成资源的浪费，可以通过定时器的控制，使得终端设备改变使用其他的BWP，从而避免通过网络侧指示终端设备切换BWP所带来的传输资源的浪费，以及避免终端长时间占用带宽资源。
此外，判断是否开启所述定时器，还可以结合DRX的状态进行后续处 理，比如，基于所述终端处于非连续接收(DRX)状态的时长、以及长DRX周期，确定是否开启定时器。
其中，所述终端的DRX状态，可以为网络侧为其进行配置，使UE在没有数据传输时不需要进入空闲模式，仍保持与基站的同步状态。
具体来说，结合DRX状态进行定时器是否开启的判断，其判断方式可以包括以下两种：
方式1、当所述终端的DRX状态处于长DRX周期的时长，大于预设时长时，确定开启定时器。
本方式，所述定时器的启动条件取决与当前配置的DRX处于long DRX cycle的时间：
比如配置一个时间x，当所述终端DRX处于long DRX cycle的时间大于等于x，则启动所述配置的定时器。
其中，时间x可以认为是预设时长，该时长可以根据实际情况进行设置，本实施例中不做限定。
方式2、当所述终端的DRX状态处于长DRX周期的数量，大于预设数量时，确定开启定时器。
其中，所述终端的DRX状态处于长DRX周期的数量，指的是，终端的DRX保持了几个长DRX周期；该数量可以取整数。
比如配置一个数量n，当所述终端DRX处于long DRX cycle的数量大于等于n，则启动所述配置的定时器。
另外，所述预设数量可以根据实际情况进行设置，本实施例中不进行穷举。
前述步骤102中，本实施例可以包含有针对不同的场景的处理，比如，当定时器失效时，确定从当前激活的第一BWP切换到第二BWP，如前文所述，这里不再进行赘述；以及另一种场景，即包含有DRX状态的一种场 景，即所述基于所述定时器，确定是否从当前激活的第一带宽部分BWP切换到第二BWP，包括：当所述定时器失效时，若所述终端处于长DRX周期，确定从当前激活的第一BWP切换到第二BWP。
其中，所述定时器失效为所述定时器的定时结束。
此时需要指出的是，当确定从当前激活的第一BWP切换到第二BWP的时候，除了进行BWP的切换之外，还可以将第一BWP对应的第一DRX配置进行去激活，并且，在激活第二BWP的时候，将第二BWP所对应的第二DRX配置进行激活。其中，所述DRX配置，可以包括有DRX的周期，包括需要监控的时间段和可能进入DRX的时间段，本实施例中不做穷举。
具体可以为，所述定时器启动之后、在失效的时候，如果终端还处于long DRX cycle，则从当前激活的第一BWP切换到第二BWP。
可以理解的是，定时器的时长可以为网络侧配置。
进一步地，在所述定时器失效之前，若终端设备不再处于长DRX周期，则停止所述定时器。也就是说，当定时器启动之后、失效之前，如果终端不再处于long DRX cycle，则停止所述定时器，直到再次启动。
其中，所述停止定时器的情况，可以有当终端设备不再处于长DRX周期的时候，将定时器停止，此时无论定时器的时长为多少均停止定时器的计时；
或者，还可以为在第一BWP上发起了RACH过程，则即便没有到定时器的时长结束的时候也停止所述定时器；
或者，当网络侧需要终端设备从一个DRX切换到新的DRX时，切换到新的DRX对应的定时器。
还需要指出的是，所述第二BWP为网络配置的默认BWP，或者，为终端设备重新激活的与第一BWP不同的BWP。也就是说，另外一个配置的带宽部分(BWP)可以是网络配置的一个默认带宽部分，也可以是一个 重新激活的另一个带宽部分。第二BWP也可以为网络侧为终端设备配置的BWP；第二BWP与第一BWP可以相同也可以不同，比如，可以相同频点并且宽度相同，当然也可以为不同频点、宽度相同，或者相同频点宽度不同，或者频点以及宽度均不相同的BWP。
还需要理解的是，终端设备可以配置两个或更多BWP；基于本实施例提供的方案，可以将当前激活的BWP均称为第一BWP，而将即将选取的BWP均作为第二BWP；如果存在更多BWP的时候，也采用上述处理方案进行处理，比如，当前将第二BWP激活，此时将第二BWP作为第一BWP执行前述步骤，当定时器失效的时候，从第一BWP切换到第二BWP的时候，此时的第二BWP可以为与前述的多个BWP均不同的第三BWP；以此类推。
第二BWP为网络配置的，网络侧可以通过调用终端设备的上行数据来确定，比如，终端设备的上行数据如果对时延敏感的，可以选取宽度较大的BWP作为第二BWP；反之，可以选取宽度较小的BWP作为第二BWP。
所述终端处于long DRX cycle的条件，可以包括以下至少之一：
通过长DRX指令MAC控制元素进行控制(也就是，Long DRX Command MAC control element控制)；
DRX短周期定时器(drxShortCycleTimer)失效；
DRX-非激活状态定时器(drx-InactivityTimer)失效；
收到一个长DRX指令MAC控制元素(DRX Command MAC control element)，同时网络没有给终端配置短DRX周期Short DRX cycle。
所述终端不处于long DRX cycle的条件，可以包括以下至少之一：
DRX-非激活状态定时器(drx-InactivityTimer)失效，同时配置了Short DRX cycle；
收到DRX Command MAC control element，同时配置了Short DRX  cycle。
可见，通过采用上述方案，就能够通过定时器，来控制是否由一个BWP切换至激活另一个BWP。从而，实现了针对BWP的切换，并且该方式能够尽可能的减少网络侧的控制信息的传输，如此保证了处理效率。
实施例二、
本发明实施例提供了一种终端设备，如图2所示，包括：
信息获取单元21，获取定时器；
处理单元22，基于所述定时器，确定是否从当前激活的第一带宽部分BWP切换到第二BWP；其中，所述第一BWP与第二BWP不同。
这里，所述BWP主要包含三个参数：Numerology：标示基础参数集，标示载波间隔SCS；中心频点；带宽：小于或者等于最大系统带宽。
由此可以看出，BWP是一个频域维度的概念。同时，现有的讨论假设在一个时间点，终端只支持一个激活的BWP。所谓激活，是指终端期望在该BWP规定的带宽上接收信号，包括数据传输(上下行)，系统消息等等。
所述信息获取单元，可以为终端设备本身默认的定时器，或者，可以为用户为终端设备配置的定时器；当然，还可以包括：获取网络侧为所述终端设备配置的所述定时器。
其中，所述网络侧为终端设备配置定时器，可以为当确定终端设备仅支持部分带宽，或者确定终端设备采用BWP进行通信的时候，网络侧为终端设备配置定时器。另外，网络侧为不同终端设备所配置的定时器可以相同也可以不同；网络侧可以基于终端设备所要进行的业务类型进行确定，比如，当终端设备需要执行的业务为传输速率较快、或者业务的传输数据较多的，可以配置宽的BWP；关于业务类型的确定可以基于QoS等参数。需要理解的是，还可以存在其他的确定BWP的方式，本实施例不进行穷举。
所述定时器的作用包括用于在其开启之后，结束之时，确定执行从当 前激活的第一带宽部分BWP切换到第二BWP的操作；也就是说，终端根据配置的定时器来决定是否从当前激活的带宽部分(BWP)切换到另外一个配置的带宽部分。
另外，所述处理单元，判断是否开启所述定时器；判断是否开启定时器的方法，还可以包括以下之一：
当终端设备传输PUSCH时，开启所述定时器；
传输无线资源控制(RRC，Radio Resource Control)信令时，开启所述定时器；
当终端设备发起随机接入成功时，开启所述定时器；
当接收到下行控制信息，且通过下行控制信息调度上下行传输的时候，开启所述定时器；所述下行控制信息，可以为DCI；
当终端设备在网络侧为其配置的资源上发送或接收数据的时候，开启所述定时器。
当所述定时器失效时，确定从当前激活的第一BWP切换到第二BWP。其中，所述定时器失效可以为所述定时器的定时结束。第二BWP也可以为网络侧为终端设备配置的BWP；第二BWP与第一BWP可以相同也可以不同，比如，可以相同频点并且宽度相同，当然也可以为不同频点、宽度相同，或者相同频点宽度不同，或者频点以及宽度均不相同的BWP，或者还可以为相同频点相同带宽，但是BWP对应不同的基础参数集(numerology)。
也就是说，当终端设备采用BWP传输业务的时候，如果在较长的时间内没有进行业务数据的发送或接收，则可能会造成资源上的浪费，因此，通过采用本实施例提供的方案，能够增加针对BWP的定时器，使得定时器失效也就是定时器结束的时候，进行BWP的切换。比如，当第一BWP的带宽较大的时候，若长时间没有业务数据的传输，就会造成资源的浪费，可以通过定时器的控制，使得终端设备改变使用其他的BWP，从而避免通 过网络侧指示终端设备切换BWP所带来的传输资源的浪费，以及避免终端长时间占用带宽资源。
此外，判断是否开启所述定时器，还可以结合DRX的状态进行后续处理，比如，具体的，基于所述终端处于非连续接收(DRX)状态的时长、以及长DRX周期，确定是否开启定时器。
其中，所述终端的DRX状态，可以为网络侧为其进行配置，使UE在没有数据传输时不需要进入空闲模式，仍保持与基站的同步状态。
进一步需要指出的是，判断方式可以包括以下两种：
方式1、所述处理单元，当所述终端的DRX状态处于长DRX周期的时长，大于预设时长时，确定开启定时器。
本方式，所述定时器的启动条件取决与当前配置的DRX处于long DRX cycle的时间：
比如配置一个时间x，当所述终端DRX处于long DRX cycle的时间大于等于x，则启动所述配置的定时器。
其中，时间x可以认为是预设时长，该时长可以根据实际情况进行设置，本实施例中不做限定。
方式2、所述处理单元，当所述终端的DRX状态处于长DRX周期的数量，大于预设数量时，确定开启定时器。
其中，所述终端的DRX状态处于长DRX周期的数量，指的是，终端的DRX保持了几个长DRX周期；该数量可以取整数。
比如配置一个数量n，当所述终端DRX处于long DRX cycle的数量大于等于n，则启动所述配置的定时器。
另外，所述预设数量可以根据实际情况进行设置，本实施例中不进行穷举。
本实施例可以包含有针对不同的场景的处理，比如，当定时器失效时， 确定从当前激活的第一BWP切换到第二BWP，如前文所述，这里不再进行赘述；以及另一种场景，即包含有DRX状态的一种场景，即所述处理单元，当所述定时器失效时，确定从当前激活的第一BWP切换到第二BWP。
其中，所述定时器失效为所述定时器的定时结束。
此时需要指出的是，当确定从当前激活的第一BWP切换到第二BWP的时候，除了进行BWP的切换之外，还可以将第一BWP对应的第一DRX配置进行去激活，并且，在激活第二BWP的时候，将第二BWP所对应的第二DRX配置进行激活。其中，所述DRX配置，可以包括有DRX的周期，包括需要监控的时间段和可能进入DRX的时间段，本实施例中不做穷举。
具体可以为，所述定时器启动之后、在失效的时候，如果终端还处于long DRX cycle，则从当前激活的第一BWP切换到第二BWP。
可以理解的是，定时器的时长可以为网络侧配置。
进一步地，在所述定时器失效之前，若终端设备不再处于长DRX周期，则停止所述定时器。也就是说，当定时器启动之后、失效之前，如果终端不再处于long DRX cycle，则停止所述定时器，直到再次启动。
其中，所述停止定时器的情况，可以有当终端设备不再处于长DRX周期的时候，将定时器停止，此时无论定时器的时长为多少均停止定时器的计时；
或者，还可以为在第一BWP上发起了RACH过程，则即便没有到定时器的时长结束的时候也停止所述定时器；
或者，当网络侧需要终端设备从一个DRX切换到新的DRX时，切换到新的DRX对应的定时器。
还需要指出的是，所述第二BWP为网络配置的默认BWP，或者，为终端设备重新激活的与第一BWP不同的BWP。也就是说，所述另外一个配置的带宽部分(BWP)可以是网络配置的一个默认带宽部分，也可以是 一个重新激活的另一个带宽部分。
