具体实施方式
现结合附图和具体实施方式对本公开实施例进一步说明。
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
需要说明的是，本公开的一个实施例中可以包括多个步骤；为了便于描述，这些个步骤被进行了编号；但是这些编号并非是对步骤之间执行时隙、执行顺序的限定；这些步骤可以以任意的顺序被实施，本公开实施例并不对此作出限定。
尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。
同LTE中的物联网设备类似，基于5G NR-lite的终端通常需要满足如下要求：低造价，低复杂度；具有一定程度的覆盖增强；功率节省。
由于目前的NR新空口是针对高速率低时延等高端终端设计的，因此当前的设计无法满足NR-lite的上述要求。因此需要对目前的NR系统进行改造用以满足NR-lite的要求。比如，为了满足低造价，低复杂度等要求，可以限制NR-IoT的RF带宽，比如限制到5M Hz或者10M Hz，或者限制NR-lite的buffer的大小，进而限制每次接收传输块的大小等等。针对功率节省，可能的优化方向是简化通信流程，减少NR-lite用户检测下行控制信道的次数等。
在NR系统中，一个服务小区可以配置带宽部分(Bandwidth part，BWP)非激活定时器(InactivityTimer)，在该定时器规定的时间范围内，用户设备在在激活BWP上没有接收到调度下行控制信息(Downlink Control Information，DCI)，则用户设备需要切换到默认BWP上。该默认BWP可以由网络配置，如果网络没有为用户设备配置默认BWP，那 么用户设备则切换到初始下行BWP上。在一种可能的实现方式中，用户设备可以根据网络侧设备的配置或是通信协议，被配置有一个或多个初始下行BWP。在本公开实施例中，“多个”是指两个或两个以上。
本公开提供的方案可用于NR-lite终端，当然也可以用于其它类型的终端。
本公开实施例提供了一种带宽部分配置方法，该方法被用户设备执行。图1是根据一示例性实施例示出的一种带宽部分配置方法的流程图，如图1所示，该方法包括：
步骤101，响应于所述用户设备配置有多个初始下行带宽部分BWP，确定所述多个初始下行BWP中之一为默认BWP；
其中，所述默认BWP为所述用户设备响应于第一定时器超时将切换到的目标BWP。
在本公开实施例中，该用户设备典型的可以为NR-lite设备。
目标BWP是指用户设备在第一定时器超时时切换到的BWP，也可以称为切换BWP。
在一实施方式中，在用户设备配置有多个初始下行BWP的场景下，用户设备确定该多个初始下行BWP中的一个初始下行BWP为默认BWP。该默认BWP为用户设备在第一定时器超时的场景下将要切换到的目标BWP。
在一实施方式中，在基于NR-lite的用户设备配置有多个初始下行BWP的场景下，用户设备确定该多个初始下行BWP中的一个初始下行BWP为默认BWP。该默认BWP为用户设备在第一定时器超时的场景下将要切换到的目标BWP。
在一实施方式中，第一定时器用于对所述用户设备在激活BWP上没有接收到调度下行控制信息的持续时间进行计时。在一实施方式中，第一定时器为BWP-InactivityTimer。当用户设备在Active BWP上接收到DCI后，第一定时器开始计时。响应于在第一定时器超时之前接收到新的DCI，该第一定时器重新开始计时。响应于第一定时器超时时依然没有接收到新的DCI，该用户设备进行BWP切换。或，用户设备在Active BWP上后第一定时器开始计时；响应于第一定时器超时时依然没有接收到DCI，则该用户设备进行BWP切换。即，所述第一定时器用于记录用户设备未接收到DCI的时间长度。其中，该第一定时器的计时时长可以为网络设备配置或根据通信协议确定。
在一实施方式中，用户设备在激活BWP上没有接收到调度下行控制信息DCI的持续时间达到规定的时间范围，例如计时器BWP-InactivityTimer超时的情况下，用户设备需要切换到默认BWP上，如果网络没有为该用户设备配置默认BWP，且该用户设备配置有多 个初始下行BWP，则用户设备确定该多个初始下行BWP中的一个初始下行BWP为默认BWP，并切换到该确定的默认BWP上。
在上述实施方式中，用户设备长时间没有接收到调度DCI时，切换到带宽较窄的初始下行BWP上，能够降低用户设备的功耗，从而更加适用于5G NR-lite系统。其中，带宽较窄是指，初始下行BWP的带宽小于激活下行BWP的带宽。或，带宽较窄是指，初始下行BWP的带宽小于阈值。
本公开实施例提供了一种带宽部分配置方法，该方法被用户设备执行。图2是根据一示例性实施例示出的一种带宽部分配置方法的流程图，如图2所示，该方法包括：
步骤201，响应于所述用户设备配置有多个初始下行带宽部分BWP，基于所述用户设备的上行BWP的配置情况，确定所述多个初始下行BWP中之一为所述默认BWP；
其中，所述默认BWP为所述用户设备响应于第一定时器超时将切换到的目标BWP。
在一实施方式中，在用户设备配置有多个初始下行BWP的场景下，用户设备基于其上行BWP的配置情况，确定该多个初始下行BWP中的一个初始下行BWP为默认BWP。该默认BWP为用户设备在第一定时器超时的场景下将要切换到的目标BWP。
在一实施方式中，通信系统为基于时分双工(Time Division Duplex，TDD)的系统，用户设备在进行BWP切换时，上行BWP和下行BWP都需要切换。因此，在用户设备配置有多个初始下行BWP的场景下，用户设备基于其上行BWP的配置情况，确定该多个初始下行BWP中的一个初始下行BWP为默认BWP。该默认BWP为用户设备在第一定时器超时的场景下将要切换到的目标BWP。在该场景下，该默认BWP和目标BWP都是指用户设备切换到的下行BWP。
在上述实施方式中，用户设备长时间没有接收到调度DCI时，切换到带宽较窄的初始下行BWP上，能够降低用户设备的功耗，从而更加适用于5G NR-lite系统。并且在用户设备配置有多个初始下行BWP的场景下，基于其上行BWP的配置情况，来确定将要切换到的默认BWP。

其中，所述第一初始下行BWP为所述多个初始下行BWP中之一；所述默认BWP为所述用户设备响应于第一定时器超时将切换到的目标BWP。
在一些可能的实现方式中，用户设备可以根据初始上行BWP与初始下行BWP之间的对应关系，确定默认BWP。例如，可以根据网络侧配置的对应关系，或根据对应的对应关系，或根据通信协议确定的对应关系；所述用户设备能够根据该对应关系确定第一初始下行BWP，并将该第一初始下行BWP作为默认BWP。
在一实施方式中，在用户设备配置有多个初始下行BWP的场景下，且在用户设备配置有一个初始上行BWP时，确定与该初始上行BWP存在对应关系的第一初始下行BWP为默认BWP。该默认BWP为用户设备在第一定时器超时的场景下将要切换到的目标BWP。这里的第一初始下行BWP为所述多个初始下行BWP中之一，第一初始下行BWP并不表示其在多个初始下行BWP中的排序。
在一实施方式中，在用户设备配置有多个初始下行BWP的场景下，且在用户设备配置有一个初始上行BWP时，确定在多个初始下行BWP中与该初始上行BWP具有相同的中心频点的一个初始下行BWP为默认BWP。该默认BWP为用户设备在第一定时器超时的场景下将要切换到的目标BWP。

步骤1101，响应于所述用户设备配置有多个初始下行带宽部分BWP，且所述多个初始下行BWP包含所述网络设备通过主系统信息块MIB配置的初始下行BWP并且所述用户设备配置有与所述通过MIB配置的初始下行BWP存在对应关系的上行BWP，确定所述通过MIB配置的初始下行BWP为所述默认BWP；
其中，所述默认BWP为所述用户设备响应于第一定时器超时将切换到的目标BWP。
其中，该对应关系可以如本公开其他实施例所述的，在此不再赘述。
在一实施方式中，在用户设备配置有多个初始下行BWP的场景下，且该多个初始下行BWP包含网络设备通过主系统信息块MIB配置的初始下行BWP，当用户设备配置有与该通过MIB配置的初始下行BWP存在对应关系的上行BWP时，网络设备确定通过MIB配置的初始下行BWP为默认BWP。该默认BWP为用户设备在第一定时器超时的场景下将要切换到的目标BWP。
在一实施方式中，通信系统为基于FDD的系统，在用户设备配置有多个初始下行BWP的场景下，且多个初始下行BWP包含所述网络设备通过主系统信息块MIB配置的初始下行BWP，当用户设备配置有与该通过MIB配置的初始下行BWP存在对应关系的上行BWP时，网络设备确定通过MIB配置的初始下行BWP为默认BWP。该对应关系为：通过MIB配置的初始下行BWP与该上行BWP具有相同的中心频点。该默认BWP为用户设备在第一定时器超时的场景下将要切换到的目标BWP。
在一实施方式中，通信系统为基于FDD的系统，在用户设备配置有多个初始下行BWP的场景下，且多个初始下行BWP包含所述网络设备通过主系统信息块MIB配置的初始下行BWP，当用户设备配置有与该通过MIB配置的初始下行BWP存在对应关系的上行BWP时，网络设备确定通过MIB配置的初始下行BWP为默认BWP。该对应关系为：该初始上行BWP包含为该用户设备配置的用于发送随机接入信息的随机接入信道，且该通过MIB配置的初始下行BWP包含为该用户设备配置的物理层信道和随机接入搜索空间；其中，所述物理层信道用于承载对应于所述随机接入信息的随机接入响应。
在上述实施方式中，用户设备长时间没有接收到调度DCI时，切换到带宽较窄的初始下行BWP上，能够降低用户设备的功耗，从而更加适用于5G NR-lite系统。在用户设备配置有多个初始下行BWP的场景下，网络设备基于用户设备的上行BWP的配置情况，来确定将要切换到的默认BWP。网络设备通过上述方法来确定用户设备将切换的到默认BWP，从而实现与BWP切换后的用户设备的通信。
本公开实施例提供了一种带宽部分配置方法，该方法被网络设备执行。图12是根据一示例性实施例示出的一种带宽部分配置方法的流程图，如图12所示，该方法包括：
步骤1201，响应于所述用户设备配置有多个初始下行带宽部分BWP，且所述多个初始下行BWP包含所述网络设备通过MIB配置的初始下行BWP，确定所述通过MIB配置的初始下行BWP为所述默认BWP；
其中，所述默认BWP为所述用户设备响应于第一定时器超时将切换到的目标BWP。
在一实施方式中，在用户设备配置有多个初始下行BWP的场景下，且该多个初始下行BWP包含网络设备通过主系统信息块MIB配置的初始下行BWP，网络设备确定通过MIB配置的初始下行BWP为默认BWP。该默认BWP为用户设备在第一定时器超时的场景下将要切换到的目标BWP。
在一实施方式中，通信系统为基于频分双工(Frequency Division Duplex，FDD)的系统，用户设备在进行BWP切换时，可以不切换上行BWP。因此，在用户设备配置有多个初始下行BWP的场景下，且该多个初始下行BWP包含网络设备通过主系统信息块MIB配置的初始下行BWP，网络设备确定通过MIB配置的初始下行BWP为默认BWP。该默认BWP为用户设备在第一定时器超时的场景下将要切换到的目标BWP。在这种场景下，不需要基于用户设备的上行BWP的配置情况来确定默认BWP。
在上述实施方式中，用户设备长时间没有接收到调度DCI时，切换到带宽较窄的初始下行BWP上，能够降低用户设备的功耗，从而更加适用于5G NR-lite系统。网络设备通过上述方法来确定用户设备将切换的到默认BWP，从而实现与BWP切换后的用户设备的通信。
本公开实施例提供了一种带宽部分配置方法，该方法被网络设备执行。该方法包括：
响应于所述用户设备配置有多个初始下行带宽部分BWP，确定所述多个初始下行BWP中之一为默认BWP；
其中，所述默认BWP为所述用户设备响应于第一定时器超时将切换到的目标BWP；所述第一定时器用于对所述用户设备在激活BWP上没有接收到调度下行控制信息的持续时间进行计时。
在一实施方式中，用户设备在激活BWP上没有接收到调度下行控制信息DCI的持续时间达到规定的时间范围的情况下，响应于该用户设备配置有多个初始下行BWP，则网络设备确定该多个初始下行BWP中的一个初始下行BWP为默认BWP，并切换到该确定的默认BWP上。
在一实施方式中，第一定时器为BWP-InactivityTimer。第一定时器的功能可以参考本公开其他实施例的描述，在此不再赘述。
在上述实施方式中，用户设备长时间没有接收到调度DCI时，切换到带宽较窄的初始 下行BWP上，能够降低用户设备的功耗，从而更加适用于5G NR-lite系统。网络设备通过上述方法来确定用户设备将切换的到默认BWP，从而实现与BWP切换后的用户设备的通信。
