具体实施方式
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发明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、本发明的一些方面相一致的装置和方法的例子。
在本公开使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也 旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开可能采用术语第一、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。例如，在不脱离本公开范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
图1是根据一示例性实施例示出的一种带宽部分切换方法的流程图，图2是根据一示例性实施例示出的一种带宽部分切换方法的应用场景图；该带宽部分切换方法可以应用在终端上，基站为该终端配置了至少一个BWP，如图1所示，该带宽部分切换方法可以包括以下步骤110-120：
在步骤110中，接收基站发送的省电信号，该省电信号为唤醒信号(Wake Up Signaling，WUS)。
本公开实施例中，基站在确定需要指示终端进行BWP切换时，可以向该终端发送省电信号，该省电信号可以为WUS；终端接收到用于指示BWP切换的省电信号后，可以根据该省电信号进行BWP切换。
其中，WUS是在新空口(New Radio，NR)通信系统中引入的一种类型的省电信号。其中，WUS是一种低功耗的检测信号，当终端检测到该WUS，则意味着后续继续监听PDCCH，否则无需监听后续的PDCCH。
在步骤120中，根据该省电信号进行BWP切换。
本公开实施例中，在根据省电信号进行BWP切换时，可以从当前激活的BWP切换至另一BWP。至于该另一BWP具体是哪个BWP，终端可以根据实际情况来决定。
在一实例性场景中，如图2所示，包括基站和终端。基站在确定需要指示终端进行BWP切换时，可以为该终端配置省电信号(例如，WUS)，并将配置的省电信号(例如，WUS)发送至终端；终端接收到省电信号(例如，WUS)后，可以根据该省电信号(例如，WUS)进行BWP切换。
由上述实施例可见，通过接收基站发送的省电信号，该省电信号为WUS，并根据该省电信号进行BWP切换，从而实现了根据基站配置的省电信号进行BWP切换 这一功能，提高了BWP切换的速率，还减少了BWP切换的功率消耗。
图3是根据一示例性实施例示出的另一种带宽部分切换方法的流程图，该带宽部分切换方法可以用于终端，并建立图1所示方法的基础上，所述省电信号为WUS；所述WUS中包括用于表征第一指定BWP的第一信息，所述第一指定BWP是所述基站为所述终端配置的用于切换的目标BWP；在执行步骤120时，如图3所示，可以包括以下步骤310-330：
在步骤310中，根据第一信息确定用于切换的第一指定BWP。
本公开实施例中，由于第一信息是用于表征第一指定BWP的信息，所以终端获知第一信息后，可以根据该第一信息确定基站配置的用于切换的目标BWP具体为哪个BWP。
在步骤320中，从当前激活的BWP切换至第一指定BWP。
本公开实施例中，终端可以按照基站的配置，从当前激活的BWP切换至基站指定的BWP。比如：当前激活的BWP为BWP1，第一指定BWP为BWP2，终端可以根据基站的指示从BWP1切换至BWP2。
在步骤330中，在第一指定BWP上进行物理下行控制信道(Physical Downlink Control CHannel，PDCCH)监听和/或物理下行共享信道(Physical Downlink Shared Channel，PDSCH)监听。
本公开实施例中，由于WUS为一种低功耗的检测信号，当终端检测到WUS，则意味着后续需要继续进行PDCCH监听，所以终端进行BWP切换后，可以在切换后的BWP上进行继续进行PDCCH监听和/或PDSCH监听。
由上述实施例可见，在省电信号为WUS，且WUS中包括用于表征第一指定BWP的第一信息时，可以根据第一信息确定用于切换的第一指定BWP，并从当前激活的BWP切换至第一指定BWP，以及在第一指定BWP上进行PDCCH监听和/或PDSCH监听，从而实现了按照基站的配置从当前激活的BWP切换至基站指定的BWP这一功能，提高了BWP切换的准确性。
图4是根据一示例性实施例示出的另一种带宽部分切换方法的流程图，该带宽部分切换方法可以用于终端，并建立图1所示方法的基础上，所述省电信号为WUS；在执行步骤120时，如图4所示，可以包括以下步骤410-430：
在步骤410中，按照第一设定规则确定用于切换的第一目标BWP。
本公开实施例中，在省电信号为WUS时，若WUS中包括用于表征第一指定BWP的第一信息，该第一指定BWP是基站为终端配置的用于切换的目标BWP，则优先根据第一信息确定用于切换的第一指定BWP；若WUS中不包括所述第一信息时，此时终端可以按照第一设定规则确定用于切换的第一目标BWP。其中，第一设定规则可以是基站通过系统消息或专用信令通知终端的，或基于通信协议规定的、且以固件形式写在终端中的。
在步骤420中，从当前激活的BWP切换至第一目标BWP。
本公开实施例中，终端可以从当前激活的BWP切换至按照第一设定规则确定的第一目标BWP。比如：当前激活的BWP为BWP1，第一目标BWP为BWP3，终端可以从BWP1切换至BWP3。
在步骤430中，在第一目标BWP上进行PDCCH监听和/或PDSCH监听。
由上述实施例可见，在省电信号为WUS，且WUS中不包括用于表征第一指定BWP的第一信息时，可以按照第一设定规则确定用于切换的第一目标BWP，并从当前激活的BWP切换至第一目标BWP，以及在第一目标BWP上进行PDCCH监听和/或PDSCH监听，从而提高了BWP切换的可靠性。
图5是根据一示例性实施例示出的一种带宽部分切换方法的流程图，该带宽部分切换方法可以应用在终端上，基站为该终端配置了至少一个BWP，如图5所示，该带宽部分切换方法可以包括以下步骤510-520：
在步骤510中，接收基站发送的省电信号，该省电信号为休眠信号(Go To Sleep，GTS)。
本公开实施例中，基站在确定需要指示终端进行BWP切换时，可以向该终端发送省电信号，该省电信号可以为GTS；终端接收到用于指示BWP切换的省电信号后，可以根据该省电信号进行BWP切换。
其中，GTS是在NR通信系统中引入的一种类型的省电信号。该GTS的含义是让终端快速进入休眠状态。
在步骤520中，根据该省电信号进行BWP切换。
本公开实施例中，在根据省电信号进行BWP切换时，可以从当前激活的BWP切换至另一BWP。至于该另一BWP具体是哪个BWP，终端可以根据实际情况来决定。
由上述实施例可见，通过接收基站发送的省电信号，该省电信号为GTS，并根据该省电信号进行BWP切换，从而实现了根据基站配置的省电信号进行BWP切换这一功能，提高了BWP切换的速率，还减少了BWP切换的功率消耗。
图6是根据一示例性实施例示出的另一种带宽部分切换方法的流程图，该带宽部分切换方法可以用于终端，并建立图5所示方法的基础上，所述省电信号为GTS；且用于终端配置有BWP不活动计时器的场景下，在执行步骤520时，如图6所示，可以包括以下步骤610-630：
在步骤610中，当配置有BWP不活动计时器(inactivity timer)时，则判断BWP不活动计时器是否处于运行状态。若是，则执行步骤620；若否，则执行步骤630。
本公开实施例中，在终端配置有BWP不活动计时器的场景下，该终端接收到GTS后，会先判断BWP不活动计时器是否处于运行状态，若是，则等待该BWP不活动计时器超时后，再进行BWP切换；若否，则直接进行BWP切换。
另外，若终端配置有BWP不活动计时器，则意味着开启了自动回退到默认BWP或初始BWP的功能。若终端未配置BWP不活动计时器，则意味着不开启从当前激活BWP自动回退到默认BWP或者初始BWP的功能。
其中，自动回退到默认BWP或初始BWP的功能具体为：若当前激活的BWP在一段时间内处于不活跃状态，则会导致BWP不活动计时器的开启，直至开启后的BWP不活动计时器超时后，终端才会从当前激活的BWP自动回退到默认BWP，如果没有配置默认BWP，则自动回退到初始BWP。其中，默认BWP可以是基站基于省电考虑而为终端专门设置的一个小BWP。
在步骤620中，不重启该BWP不活动计时器，直至BWP不活动计时器超时后，再从当前激活的BWP回退至默认BWP或初始BWP。
在步骤630中，从当前激活的BWP回退至默认BWP或初始BWP。
上述步骤620和步骤630中，在从当前激活的BWP回退至默认BWP或初始BWP时，可以首选回退到默认BWP，若没有配置默认BWP，再自动回退到初始BWP。
由上述实施例可见，在省电信号为GTS，且配置有BWP不活动计时器时，可 以先判断BWP不活动计时器是否处于运行状态，若是，则不重启该BWP不活动计时器，直至BWP不活动计时器超时后，再从当前激活的BWP回退至默认BWP或初始BWP；若否，则从当前激活的BWP回退至默认BWP或初始BWP，从而实现了配置有BWP不活动计时器的场景下的BWP切换，提高了BWP切换的实用性。
图7是根据一示例性实施例示出的另一种带宽部分切换方法的流程图，该带宽部分切换方法可以用于终端，并建立图5所示方法的基础上，所述省电信号为GTS；且用于终端配置有BWP不活动计时器的场景下，在执行步骤520时，如图7所示，可以包括以下步骤710-730：
在步骤710中，当配置有BWP不活动计时器(inactivity timer)时，则判断BWP不活动计时器是否处于运行状态。若是，则执行步骤720；若否，则执行步骤730。
在步骤720中，终止BWP不活动计时器，即视为该BWP不活动计时器超时，并从当前激活的BWP切换至默认BWP或初始BWP。
在步骤730中，从当前激活的BWP回退至默认BWP或初始BWP。
上述步骤720和步骤730中，在从当前激活的BWP回退至默认BWP或初始BWP时，可以首选回退到默认BWP，若没有配置默认BWP，再自动回退到初始BWP。
由上述实施例可见，在省电信号为GTS，且配置有BWP不活动计时器时，可以先判断BWP不活动计时器是否处于运行状态，若是，则终止BWP不活动计时器，并从当前激活的BWP切换至默认BWP或初始BWP；若否，则从当前激活的BWP回退至默认BWP或初始BWP，从而扩展了BWP切换的实现方式，还满足了针对BWP切换的不同个性需求。
图8是根据一示例性实施例示出的另一种带宽部分切换方法的流程图，该带宽部分切换方法可以用于终端，并建立图5所示方法的基础上，所述省电信号为GTS；且用于终端未配置BWP不活动计时器的场景下，所述GTS中包括用于表征第二指定BWP的第二信息，所述第二指定BWP是所述基站为所述终端配置的用于回退的目标BWP；在执行步骤520时，如图8所示，可以包括以下步骤810-820：
在步骤810中，根据第二信息确定用于回退的第二指定BWP。
本公开实施例中，由于第二信息是用于表征第二指定BWP的信息，所以终端获知第二信息后，可以根据该第二信息确定基站配置的用于回退的目标BWP具体为 哪个BWP。
在一实施例中，终端配置有BWP不活动计时器，若终端接收到基站发送的GTS中包括用于表征第二指定BWP的第二信息，所述第二指定BWP是所述基站为所述终端配置的用于回退的目标BWP，该终端仍旧会根据该GTS指示的目标BWP进行回退。
在一实施例中，终端未配置BWP不活动计时器，若终端接收到基站发送的GTS中包括用于表征第二指定BWP的第二信息，所述第二指定BWP是所述基站为所述终端配置的用于回退的目标BWP，该终端会根据该GTS指示的目标BWP进行回退。
在步骤820中，从当前激活的BWP回退至第二指定BWP。
本公开实施例中，终端可以按照基站的配置，从当前激活的BWP回退至基站指定的BWP。比如：当前激活的BWP为BWP1，第二指定BWP为默认BWP，终端可以根据基站的指示从BWP1回退至默认BWP。其中，默认BWP可以是基站基于省电考虑而为终端专门设置的一个小BWP。
由上述实施例可见，在省电信号为GTS，且GTS中包括用于表征第二指定BWP的第二信息时，可以根据第二信息确定用于回退的第二指定BWP，并从当前激活的BWP回退至第二指定BWP，从而实现了按照基站的配置从当前激活的BWP回退至基站指定的BWP这一功能，提高了BWP切换的可靠性。
图9是根据一示例性实施例示出的另一种带宽部分切换方法的流程图，该带宽部分切换方法可以用于终端，并建立图5所示方法的基础上，所述省电信号为GTS；且用于终端未配置BWP不活动计时器的场景下，在执行步骤520时，如图9所示，可以包括以下步骤910-920：
在步骤910中，当未配置BWP不活动计时器时，则按照第二设定规则确定用于回退的第二目标BWP。
本公开实施例中，在终端未配置BWP不活动计时器、且GTS中不包括用于表征第二指定BWP的第二信息，所述第二指定BWP是所述基站为所述终端配置的用于回退的目标BWP时，终端可以按照第二设定规则来确定用于回退的第二目标BWP。其中，第二设定规则可以是所述基站通过系统消息或专用信令通知所述终端的，或基于通信协议规定的、且以固件形式写在所述终端中的。
在一实施例中，所述按照第二设定规则可以包括以下至少一项：
所述第二目标BWP为默认BWP；
所述第二目标BWP为初始BWP；
在所述默认BWP未配置时，所述第二目标BWP为所述初始BWP；
在所述默认BWP已配置时，所述第二目标BWP为所述默认BWP。
在步骤920中，从当前激活的BWP回退至第二目标BWP。
由上述实施例可见，当未配置BWP不活动计时器时，可以按照第二设定规则确定用于回退的第二目标BWP，比如：该第二设定规则可以是基站通过系统消息或专用信令通知终端的，或基于通信协议规定的、且以固件形式写在终端中的，并从当前激活的BWP回退至第二目标BWP，从而实现了未配置有BWP不活动计时器的场景下的BWP切换，提高了BWP切换的应用范围。
图10是根据一示例性实施例示出的一种带宽部分切换方法的流程图，该带宽部分切换方法可以应用在基站上，该基站为终端配置了至少一个BWP，如图10所示，该带宽部分切换方法可以包括以下步骤1010-1020：
在步骤1010中，当确定需要指示终端进行BWP切换时，为该终端配置省电信号，该省电信号为唤醒信号WUS。
本公开实施例中，基站在确定需要指示终端进行BWP切换时，可以向该终端发送为省电信号，该省电信号为WUS；终端接收到省电信号后，可以根据该省电信号进行BWP切换。
