Description

一种带宽部分的配置方法及装置
本申请要求于2018年10月26日提交国家知识产权局、申请号为201811256581.X、申请名称为“一种带宽部分的配置方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请的实施例涉及通信技术领域，尤其涉及一种带宽部分的配置方法及装置。
背景技术
下一代接入网新空口(new radio，NR)中为了能够更精确的适配数据所用带宽并且节省终端设备耗电，引入了带宽部分(bandwidth part，BWP)。在NR R15(版本15)中，BWP有两种状态，active(激活态)和deactivated(去激活态)。BWP在2种状态间切换，会使功能电路频繁全开、全关。例如，UE在激活态的BWP上，需要开启全部功能电路实现接收下行信道，如：物理下行共享信道(physical downlink shared channel，PDSCH)、物理下行控制信道(physical downlink control channel，PDCCH)，并且测量、上报信道质量指示(channel quality indication，CQI)；UE在去激活态的BWP上需要关闭全部功能电路，不接收下行信道PDSCH、PDCCH，也不会测量、上报CQI。这样，BWP在2种状态间切换，会使功能电路全开转换为全关，或者功能电路全关转换为全开。而BWP在状态由去激活态切换至激活态时功能电路全关转换为全开，或者BWP在状态由激活态切换至去激活态时功能电路全开转换为全关，这种功能电路的开关转换会存在较高的时延，同时对终端设备来说也比较耗电。

具体实施方式
下面将结合本申请实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
在本申请的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。并且，在本申请的描述中，除非另有说明，“多个”是指两个或多于两个。
另外，为了便于清楚描述本申请实施例的技术方案，本申请实施例中所述的“第一”和“第二”等是用于区别不同的对象，或者用于区别对同一对象的不同处理，而不是用于描述对象的特定顺序。例如，在本申请中，第一状态和第二状态是不同状态，例如，终端设备在第一状态的第一带宽部分上开启部分功能时，第一状态可以叫做休眠态；终端设备在第一状态的第一带宽部分上开启全部功能时，第一状态可以叫做激活态；终端设备在第一状态的第一带宽部分上关闭全部功能时，第一状态可以叫做去激活态；类似的，终端设备在第二状态的第一带宽部分上开启部分功能时，第二状态可以叫做休眠态；终端设备在第二状态的第一带宽部分上开启全部功能时，第二状态可以叫做激活态；终端设备在第二状态的第一带宽部分上关闭全部功能时，第二状态可以叫做去激活态。当然以上激活态(active)、休眠态(dormant)以及去激活态(deactivated/inactive)只是一种示例性的说明。在一些方案中还可以有其他的叫法，例如，激活态在一些实施例中也可以称作唤醒态，休眠态在一些实施例中也可以叫做待机态，去激活态在一些实施例中也可以称作闲置态等等，以上各个状态的名称只是为了区别其对应的带宽部分处于不同的状态，其具体含义可以参考对各个状态的功能的定义。其中在各状态中开启或者关闭的功能可以包括但不限于：监听下行信道、接收下行信道、发送上行信道、测量、上报测量结果、接收下行信号(如导频)、发送上行信号(如导频)等等。其中，下行信道包括：物理下行共享信道(physical downlink shared channel，PDSCH)、物理下行控制信道(physical downlink control channel，PDCCH)、PHICH(Physical hybrid ARQ indicator channel，物理混合自动重传指示信道)，PCFICH(physical control format indicator channel，物理控制格式指示信道)、物理多播信道(physical multicast channel，PMCH)、物理广播信道(physical broadcast channel，PBCH)等等。其中，上行信道包括：物理上行共享信道(physical uplink shared channel，PUSCH)、理上行控制信道(physical uplink control channel，PUCCH)、物理随机接入信道(physical random access channel，PRACH)等等。测量包括：层1(lay1，物理层)测量，如，信道状态信息(channel state information，CSI)、信道质量指示(channel quality indication，CQI)测量；层2(lay2，数据链路层)测量，如无线资源管理(radio resource management，RRM)测量；层3(lay3，网络层)测量， 如RRM测量等等。上报测量结果包括：层1测量结果上报，如CSI、CQI上报；层2或层3测量结果上报，如参考信号接收功率(reference signal received power，RSRP)、参考信号接收质量(reference signal receiving quality，RSRQ)上报等等。下行信号包括：解调参考信号(demodulation reference signal，DMRS)，相位跟踪参考信号(phase-tracking reference signal，PTRS)，信道状态信息参考信号(channel-state information reference signal，CSI-RS)，小区参考信号(cell specific reference signal，CRS)等等。上行信号包括：DMRS，探测参考信号(sounding reference signal，SRS)等等。示例性的，终端设备在激活态的带宽部分上开启全部功能，例如：终端设备在激活态的带宽部分开启全部功能电路实现接收下行信道，如：PDSCH、PDCCH，并且测量、上报CQI；终端设备在去激活的带宽部分上关闭全部功能，例如：终端设备在去激活态的带宽部分上需要关闭全部功能电路，不接收下行信道PDSCH、PDCCH，也不会测量、上报CQI；终端设备在休眠态的带宽部分上开启部分功能，例如：终端设备在休眠态的带宽部分上开启部分功能电路，不接收下行信道PDSCH、PDCCH，但是会测量、上报CQI。以上仅是一种示例，终端设备在带宽部分开启的功能用于处理该带宽部分上传输的信号，这些信号可以是数据或控制信令，当然以节省终端设备的能耗为目的可以在带宽部分上关闭部分功能，这样相对于在带宽部分上开启全部功能，可以降低终端设备的功耗，据此原理将终端设备在带宽部分上所处的状态分为上述的三个状态，其中本申请的实施例中不对带宽部分开启部分功能时，具体应该开启的部分功能做限定。
其中，本申请的实施例提供的带宽部分指终端设备使用链路的一部分带宽传输数据。一种可能的方式中，这一部分带宽可以自适应变化，因此也可以用带宽自适应变化(bandwidth adaptation)指代带宽部分BWP技术，以下实施例中将带宽部分简称为BWP。
在LTE中，终端设备的带宽跟系统的带宽保持一致，解码主信息块(master information blocks，MIB)信息配置带宽后便保持不变。在NR中，终端设备的带宽可以动态的变化。例如，在第一时刻，终端的业务量较大，接入网设备给终端设备配置一个大带宽(BWP1)；第二时刻，终端设备的业务量较小，接入网设备给终端设备配置了一个小带宽(BWP2)，满足基本的通信需求即可；第三时刻，接入网设备发现BWP1所在带宽内有大范围频率选择性衰落，或者BWP1所在频率范围内资源较为紧缺，还可以给终端设备配置了一个新的带宽(BWP3)。
一种可能的方式中，每个BWP频点和带宽不同，可选的，每个BWP还可以对应不同的配置。比如，每个BWP的子载波间隔，循环前缀(cyclic prefix，CP)类型，同步信号块(synchronisation signal block，SSB；其中SSB包括：主同步信号块(primary synchronization signal block，PSS block)、辅同步信号块(secondary synchronization signal block，SSS block)以及物理广播信道块(physical broadcast channel block，PBCH block)周期等都可以差异化配置，以适应不同的业务。
本申请的实施例应用于图1所示的通信系统。该通信系统包括终端设备12(12-1～12-n)和接入网设备11，其中接入网设备可以为收发节点、移动管理节点(mobility management entity，MME)或者基站(gNB)。本申请的的通信系统可以 应用于5G(NR)独立(standalone，SA)组网的架构，或者LTE/5GC非独立(non-standalone，NSA)组网的架构，或者后续演进的其他系统架构。在该通信系统中，接入网设备可以为终端设备配置至少一个带宽部分用于信号的传输。
目前的现有技术中，BWP有两种状态，active(激活态)和deactivated(去激活态)。在NR中，支持一个BWP在2种状态间的切换，即，一个BWP可以从激活态切换为去激活态，也可以从去激活态切换为激活态；还支持了一个UE在不同的BWP之间切换的机制。比如，一个UE在一个BWP上收发数据，这个BWP是激活态，UE处于这个BWP上时，就会开启一个计时器(timer)，这个timer的值bwp-InactivityTimer(BWP的去激活时间)是网络侧配置的。当这个timer到期时，UE会回到一个默认BWP上，而不会再位于这个BWP上，默认BWP是网络侧配置的。如果网络侧没有配置，那么UE会回到初始BWP上(初始BWP也是网络侧配置的)。NR中还支持基于网络侧信令配置而UE在不同的BWP之间切换的机制。比如，一个UE在一个BWP上收发数据，这个BWP是激活态。UE在这个BWP上接收了网络侧下发的下行资源控制信令DCI，该DCI中指示出了BWP的标识，那么UE会切换到DCI中指示的BWP上。比如，UE在BWP1上收发数据，UE在BWP1上收到了DCI，该DCI中指示了BWP ID＝2，那么UE就会切换到BWP2上。然而，BWP在2种状态间切换，会使功能电路频繁全开、全关。这样，BWP在2种状态间切换，会使功能电路全开转换为全关，或者功能电路全关转换为全开，对UE来说比较耗电，而且时延较长。
针对上述问题，本申请实施例提供一种带宽部分的配置方法，包括：从接入网设备接收第一信息；根据第一信息确定是否将第一带宽部分从第一状态切换至第二状态，其中，第一状态和第二状态中的一种状态为第一带宽部分开启部分功能的状态，另一种状态为第一带宽部分开启全部功能或者关闭全部功能的状态。在本申请的实施例中，增加了一种第一带宽部分所处的状态，在该状态下，第一带宽部分开启部分功能；则，当终端设备在从其他状态转换到该状态，或者从该状态转换到其他状态时，无需关闭或者开启第一带宽部分的全部功能，因此能够降低时延，并节省终端设备的耗电。
本申请实施例中的终端设备可以是指能够与基站实现信息交互的UE，例如：手机(如图2所示的手机200)、平板电脑、个人计算机PC、个人数字助理PDA、智能手表、上网本、可穿戴电子设备等，本申请实施例对该设备的具体形式不做特殊限制。接入网设备可以为：收发节点、移动管理节点或者基站(如图3所示的基站)。
如图2所示，以手机200作为上述终端设备举例，手机200具体可以包括：处理器201、射频RF电路202、存储器203、触摸屏204、蓝牙装置205、一个或多个传感器206、无线保真Wi-Fi装置207、定位装置208、音频电路209、外设接口210以及电源装置211等部件。这些部件可通过一根或多根通信总线或信号线(图2中未示出)进行通信。本领域技术人员可以理解，图2中示出的硬件结构并不构成对手机的限定，手机200可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
下面结合图2对手机200的各个部件进行具体的介绍：
处理器201是手机200的控制中心，利用各种接口和线路连接手机200的各个部分，通过运行或执行存储在存储器203内的应用程序，以及调用存储在存储器203内 的数据，执行手机200的各种功能和处理数据。在一些实施例中，处理器201可包括一个或多个处理单元。在本申请实施例一些实施例中，上述处理器201还可以包括指纹验证芯片，用于对采集到的指纹进行验证。

存储器203用于存储应用程序以及数据，处理器201通过运行存储在存储器203的应用程序以及数据，执行手机200的各种功能以及数据处理。存储器203主要包括存储程序区以及存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像处理功能等)；存储数据区可以存储根据使用手机200时所创建的数据(比如音频数据、电话本等)。此外，存储器203可以包括高速随机存取存储器(RAM)，还可以包括非易失存储器，例如磁盘存储器件、闪存器件或其他易失性固态存储器件等。存储器203可以存储各种操作系统，例如，iOS操作系统，Android操作系统等。上述存储器203可以是独立的，通过上述通信总线与处理器201相连接；存储器203也可以和处理器201集成在一起。
触摸屏204具体可以包括触控板204-1和显示器204-2。
其中，触控板204-1可采集手机200的用户在其上或附近的触摸事件(比如用户使用手指、触控笔等任何适合的物体在触控板204-1上或在触控板204-1附近的操作)，并将采集到的触摸信息发送至其他器件(例如处理器201)。其中，用户在触控板204-1附近的触摸事件可以称之为悬浮触控；悬浮触控可以是指，用户无需为了选择、移动或拖动目标(例如图标等)而直接接触触控板，而只需用户位于设备附近以便执行所想要的功能。此外，可以采用电阻式、电容式、红外线以及表面声波等多种类型来实现触控板204-1。
显示器(也称为显示屏)204-2可用于显示由用户输入的信息或提供给用户的信息以及手机200的各种菜单。可以采用液晶显示器、有机发光二极管等形式来配置显示器204-2。触控板204-1可以覆盖在显示器204-2之上，当触控板204-1检测到在其上或附近的触摸事件后，传送给处理器201以确定触摸事件的类型，随后处理器201可以根据触摸事件的类型在显示器204-2上提供相应的视觉输出。虽然在图2中，触控板204-1与显示屏204-2是作为两个独立的部件来实现手机200的输入和输出功能，但是在某些实施例中，可以将触控板204-1与显示屏204-2集成而实现手机200的输入和输出功能。可以理解的是，触摸屏204是由多层的材料堆叠而成，本申请实施例中只展示出了触控板(层)和显示屏(层)，其他层在本申请实施例中不予记载。另外，触控板204-1可以以全面板的形式配置在手机200的正面，显示屏204-2也可以以全面板的形式配置在手机200的正面，这样在手机的正面就能够实现无边框的结构。
另外，手机200还可以具有指纹识别功能。例如，可以在手机200的背面(例如 后置摄像头的下方)配置指纹识别器212，或者在手机200的正面(例如触摸屏204的下方)配置指纹识别器212。又例如，可以在触摸屏204中配置指纹采集器件212来实现指纹识别功能，即指纹采集器件212可以与触摸屏204集成在一起来实现手机200的指纹识别功能。在这种情况下，该指纹采集器件212配置在触摸屏204中，可以是触摸屏204的一部分，也可以以其他方式配置在触摸屏204中。本申请实施例中的指纹采集器件222的主要部件是指纹传感器，该指纹传感器可以采用任何类型的感测技术，包括但不限于光学式、电容式、压电式或超声波传感技术等。

Wi-Fi装置207，用于为手机200提供遵循Wi-Fi相关标准协议的网络接入，手机200可以通过Wi-Fi装置207接入到Wi-Fi接入点，进而帮助用户收发电子邮件、浏览网页和访问流媒体等，它为用户提供了无线的宽带互联网访问。在其他一些实施例中，该Wi-Fi装置207也可以作为Wi-Fi无线接入点，可以为其他设备提供Wi-Fi网络接入。
定位装置208，用于为手机200提供地理位置。可以理解的是，该定位装置208具体可以是全球定位系统(global positioning system，GPS)或北斗卫星导航系统、俄罗斯GLONASS等定位系统的接收器。定位装置208在接收到上述定位系统发送的地理位置后，将该信息发送至处理器201进行处理，或者发送至存储器203进行保存。在另外的一些实施例中，该定位装置208还可以是辅助全球卫星定位系统AGPS的接收器，AGPS系统通过作为辅助服务器来协助定位装置208完成测距和定位服务，在这种情况下，辅助定位服务器通过无线通信网络与设备例如手机200的定位装置208(即GPS接收器)通信而提供定位协助。在另外的一些实施例中，该定位装置208也可以是基于Wi-Fi接入点的定位技术。由于每一个Wi-Fi接入点都有一个全球唯一的MAC地址，设备在开启Wi-Fi的情况下即可扫描并收集周围的Wi-Fi接入点的广播信号，因此可以获取到Wi-Fi接入点广播出来的MAC地址；设备将这些能够标示Wi-Fi接入点的数据(例如MAC地址)通过无线通信网络发送至位置服务器，由位置服务器检索出每一个Wi-Fi接入点的地理位置，并结合Wi-Fi广播信号的强弱程度，计算出该设备的地理位置并发送到该设备的定位装置208中。
音频电路209、扬声器213、麦克风214可提供用户与手机200之间的音频接口。音频电路209可将接收到的音频数据转换后的电信号，传输到扬声器213，由扬声器 213转换为声音信号输出；另一方面，麦克风214将收集的声音信号转换为电信号，由音频电路209接收后转换为音频数据，再将音频数据输出至RF电路202以发送至比如另一手机，或者将音频数据输出至存储器203以便进一步处理。
外设接口210，用于为外部的输入/输出设备(例如键盘、鼠标、外接显示器、外部存储器、用户识别模块卡等)提供各种接口。例如通过通用串行总线USB接口与鼠标连接，通过用户识别模块卡卡槽上的金属触点与电信运营商提供的用户识别模块卡SIM卡进行连接。外设接口210可以被用来将上述外部的输入/输出外围设备耦接到处理器201和存储器203。
在本申请实施例中，手机200可通过外设接口210与设备组内的其他设备进行通信，例如，通过外设接口210可接收其他设备发送的显示数据进行显示等，本申请实施例对此不作任何限制。
手机200还可以包括给各个部件供电的电源装置211(比如电池和电源管理芯片)，电池可以通过电源管理芯片与处理器201逻辑相连，从而通过电源装置211实现管理充电、放电、以及功耗管理等功能。
尽管图2未示出，手机200还可以包括摄像头(前置摄像头和/或后置摄像头)、闪光灯、微型投影装置、近场通信NFC装置等，在此不再赘述。

其中，第一状态和第二状态中的一种状态为第一带宽部分开启部分功能的状态，另一种状态为第一带宽部分开启全部功能或者关闭全部功能的状态。
在本申请的实施例中，存在一种不同于激活态和去激活态的一种状态，在该状态下，第一带宽部分开启部分功能；则，当终端设备在从其他状态转换到该状态，或者从该状态转换到其他状态时，无需关闭或者开启第一带宽部分的全部功能，因此能够降低时延，并节省终端设备的耗电。
另外，在一些实施例中，第一带宽部分的状态切换是与带宽部分切换相结合的，例如，当第一带宽部分切换至第二带宽部分时，第一带宽部分发生状态的切换和/或第二带宽部分发生状态的切换。
在一些实施例中，第一信息可以同时控制带宽部分的切换以及带宽部分的状态切换，比如：第一状态为第一带宽部分开启全部功能的状态，第二状态为第一带宽部分开启部分功能的状态时，还包括：根据第一信息确定从第一带宽部分切换至第二带宽部分。又比如：第一状态为第一带宽部分开启部分功能的状态，第二状态为第一带宽部分开启全部功能的状态时，还包括：根据第一信息确定从第二带宽部分切换至第一带宽部分。
在一些实施例中，还可以通过第一信息控制带宽部分的状态切换，通过第二信息或第三信息控制带宽部分的切换，比如：第一状态为第一带宽部分开启全部功能的状态，第二状态为第一带宽部分开启部分功能的状态时，还包括：从接入网设备接收第二信息；根据第二信息确定从第一带宽部分切换至第二带宽部分，其中第二带宽部分 为开启全部功能的状态。又比如：第一状态为第一带宽部分开启部分功能的状态，第二状态为第一带宽部分开启全部功能的状态时，还包括：从接入网设备接收第三信息；根据第三信息确定从第二带宽部分切换至第一带宽部分。
下面结合第一信息、第二信息以及第三信息的具体形式对本申请的带宽部分的配置方法进行举例说明。
在一些实施例中，第一信息可以仅用于控制带宽部分的状态切换。可选的，第一信息可以为控制带宽部分的状态切换的信息，其具有二象性，例如：第一信息是个1bit的信息，第一信息指示出的是：是或否的含义。是或否的含义可以根据第一信息的比特明确指示出来，比如，1表示是，0表示否。是或否的含义还可以根据第一信息的指示形式而确定出来，比如，这个第一信息是可选的信元(optional information element，optional IE)，那么这个第一信息配置给了终端设备并且有指示的内容则表示“是”，如果这个指示信息没有被配置给终端设备则表示“否”。
可以理解的，带宽部分可以包括三种状态：开启部分功能的状态、开启全部功能的状态、以及关闭全部功能的状态。以下实施例中将开启部分功能的状态称作休眠态，将开启全部功能的状态称作激活态，将关闭全部功能的状态称作去激活态。
本申请实施例中，可以定义三种状态按照固定顺序切换，例如：激活态->休眠态->去激活态->激活态，比如，对于一个休眠态的BWP，终端设备根据第一信息确定需要进行状态切换，那么终端设备将这个BWP的状态一定是从休眠态切换到去激活态。如果未定义三种状态的切换顺序，即三种状态可以随机切换的话，那么第一信息中可以包含状态的标识，例如：00表示:激活态，01表示:休眠态，10表示:去激活态，11表示:预留，那么第一信息中可以包含2个bit(比特)，用来指示BWP要切换到哪个状态去，比如，当前BWP上终端设备接收到了一个MAC-CE信令，该信令指示了01，则表示该BWP的状态切换为休眠。当然，采用2个bit作为状态的标识仅是一种示例，并不构成对本申请的限制，在一些实施例中还可以采用其他方式例如更多或者更少的bit作为状态的标识。需要说明的是，在未定义三种状态的切换顺序时，第一信息中可以包含“需要切换状态”的指示以及将切换至的状态的标识，或者，第一信息可以仅包含将切换至的状态的标识，即“需要切换状态”的指示可以采用缺省的方式，当收到切换至的状态的标识时，即表示默认需要切换状态。
一种可能的方式中，第一信息可以是在一个激活态的BWP上传输至终端设备的。如果当前BWP处于激活态时，可以通过当前BWP传输第一信息，第一信息可以仅包含指示状态切换的信息，其默认为对当前BWP的状态的切换指示。可选的，第一信息也可以是通过任一处于激活态的BWP传输，此时第一信息还可以包含指示状态切换的BWP的标识。因此，第一信息中还可以包含BWP的标识，以及指示状态切换的标识。即，通过第一信息指示：哪个BWP需要切换状态。比如，第一信息可以为在DCI信令中配置的3个bit的字段，前2个bit指示哪个BWP(即，指示BWP的ID)，后1个bit指示BWP需要切换状态需或不需要切换状态。示例性的：BWP1的状态已处于休眠态，终端设备在BWP0上传输数据。终端设备在BWP0上接收到了接入网设备发送的第一信息，例如，DCI信令，该DCI信令里指示了BWP ID＝1及需要切换的状态(共3个bit指示：011)，则该DCI表示了BWP1需要切换状态，相当于BWP1 的状态从休眠态切换为去激活态。一种可能的方式中，第一信息中可以包含BWP的标识以及状态的标识，例如，当三种状态按照可以随机切换时，第一信令中可以包括4个bit，协议中可以规定前2个bit指示了BWP的标识，后2个bit指示了状态的标识，那么0110则表示了ID＝1的BWP的状态切换为去激活态。当然，以上采用3个bit同时指示BWP的标识以及状态切换的指示，采用4个bit同时指示BWP的指示以及切换的状态的标识仅是一种示例，并不构成对本申请的限制，在一些实施例中，还可以用分开的bit分别指示BWP的标识以及状态切换的指示或者切换的状态的标识，当然也可以采用其他的划分方式，例如在连续的多个bit中，采用前边的若干bit指示状态切换的指示或者切换的状态的标识，后边的若干bit指示BWP的标识等等。
又一种可能的方式中，第一信息可以包含定时器的超时时间，则在定时器超时时，确定将第一带宽部分从第一状态切换至第二状态。可以理解的是，可以是直接通过定时器配置带宽部分的状态切换，也可以是将定时器和前面所描述的指示信息、状态标识进行结合控制带宽部分的状态切换。例如：
第一、可以通过定时器控制带宽部分在激活态到休眠态的切换，比如，如图5所示，接入网设备通过配置信息配置第一定时器的超时时间为第一时长，例如，该配置信息可以为预定义的，或者通过广播下发的，则第一计时器超时时，终端设备控制BWP的状态从激活态切换为休眠态。其中，BWP的状态是从哪个状态切换到哪个状态，可以是约定的，例如协议规定好的。例如，终端设备本来在BWP上传输数据，即BWP为激活态，当确定BWP上无数据传输时或者持续预定时长无数据传输时，终端设备启动第一定时器，当第一定时器超时时，终端设备将BWP的状态从激活态切换为休眠态。又比如，BWP进入激活态时，启动第一定时器，当第一定时器超时时，这个BWP从激活态切换为休眠态。其中第一信息可以是接入网设备由广播消息或者RRC信令发送给UE的。又比如，可以是终端设备收到用于指示进行状态切换的第一信息(当然该第一信息可以为上述实施例中的包含“需要切换状态”的指示和/或将切换至的状态的标识的第一信息)后启动该第一定时器，在第一定时器超时时，对BWP进行状态切换。
第二，可以通过定时器控制带宽部分在休眠态到去激活态的切换，比如，如图6所示，接入网设备通过配置信息配置第二定时器的第二时长，例如，该配置信息可以为预定义的，或者通过广播下发的，则第二定时器超时时，终端设备控制BWP的状态从休眠态切换为激活态。其中，BWP进入休眠态时，启动第二定时器。又比如，可以是终端设备收到用于指示进行状态切换的第一信息(当然该第一信息可以为上述实施例中的包含“需要切换状态”的指示和/或将切换至的状态的标识的第一信息)后启动该第二定时器，在第二定时器超时时，对BWP进行状态切换。
通常，在一些实施例中，BWP的状态切换伴随BWP的切换，则控制BWP切换的指令可以采用第一信息，或者采用与第一信息区别的其他信息。
在一种实施例中，可以通过第一信息同时控制带宽部分的切换以及带宽部分的状态切换。如果当前BWP处于激活态时，可以通过当前BWP传输第一信息，第一信息可以包含指示带宽部分切换的信息，其默认为将当前BWP切换为其他BWP例如回退到默认BWP或者初始BWP；可以理解的，第一信息也可以是通过任一处于激活态的 BWP传输，此时第一信息还可以包含BWP的标识，则终端设备在接收到该第一信息后从当前BWP切换至第一信息中的BWP的标识对应的BWP。比如：如图7所示，终端设备在BWP1上接收到了接入网设备发送的第一信息，如，RRC信令，或者，MAC-CE信令，或者DCI信令，在配置的第一信息中包括了一个BWP的标识，比如，通过BWP ID表示BWP的标识，比如BWP ID＝2，那么终端设备将从BWP1切换到BWP2，意味着，终端设备将在BWP2上传输数据。则接入网设备发送的第一信息也同时指示了，BWP1的状态需要转换，例如从激活态变为休眠态。另外，由于需要在BWP2上传输数据，则需要将BWP2的状态切换为激活态。BWP2可以处于休眠态，也可以处于去激活态或者激活态，那么BWP2的状态将切换为激活态。当然，若BWP2本身处于激活态，则保持其处于激活态。又比如：接入网设备通过配置信息配置了第一定时器的时长，例如，该配置信息可以为预定义的，或者通过广播下发的，则第一定时器超时时，终端设备将第一带宽部分切换至第二带宽部分，同时终端设备将第一带宽部分的状态从激活态切换到休眠态。示例性的，终端设备UE本来在BWP1上传输数据，当确定BWP1上无数据传输时，终端设备开启第一定时器，当第一定时器超时时，终端设备回退到BWP0(BWP0是接入网设备配置的默认BWP；如果接入网设备没有配置默认BWP，那么BWP0指接入网设备配置的初始BWP)。BWP1的状态从激活态切换为休眠态，BWP0的状态切换为激活态。
或者，可以是终端设备收到用于指示带宽部分切换的第一信息(当然该第一信息可以包含指示带宽部分切换的信息)后启动该第一定时器，在第一定时器超时时，对BWP切换。
在另一种实施例中，通过第一信息同时控制带宽部分的切换以及带宽部分的状态切换时，可以根据第一信息确定从第二带宽部分切换至第一带宽部分。比如：如图8所示，终端设备在BWP2上接收到了接入网设备发送的第一信息，如，RRC信令，或者，MAC-CE信令，或者DCI信令，在配置的第一信息中包括了一个BWP的标识，比如BWP ID＝1，那么终端设备将从BWP2切换到BWP1，意味着，终端设备将在BWP1上传输数据。则接入网设备发送的第一信息也同时指示了，BWP1的状态切换为激活态，当然，可以为无论BWP1当前处于何种状态(例如可以是休眠态或者去激活态或者激活态)，则需要将BWP1的状态切换为激活态，当然，若BWP1本身处于激活态，则保持其处于激活态。
在一些实施例中，可以采用与第一信息区别的其他信息控制带宽部分之间的切换。示例性的，第一状态为第一带宽部分开启全部功能的状态，第二状态为第一带宽部分开启部分功能的状态时，终端设备从接入网设备接收第二信息；根据第二信息确定从第一带宽部分切换至第二带宽部分。比如，终端设备在BWP1上接收到了接入网设备发送的第二信息，如，RRC信令，或者，MAC-CE信令，或者DCI信令，在配置的第一信息中包括了一个BWP的标识，比如BWP ID＝2，那么终端设备将从BWP1切换到BWP2，意味着，终端设备将在BWP2上传输数据。此时，通常会结合BWP1的状态切换，则终端设备在BWP1上接收到了接入网设备发送的第一信息，如，RRC信令，或者，MAC-CE信令，或者DCI信令，在配置的第一信息中包括了一个BWP的标识，比如BWP ID＝2，则意味着，终端设备将在BWP2上传输数据，则接入网设备发送的 第一信息指示了BWP1的状态从激活态变为休眠态。另外，由于需要在BWP2上传输数据，则无论BWP2当前处于何种状态(例如可以是休眠态或者去激活态或者激活态)，则需要将BWP2的状态切换为激活态，当然，若BWP2本身处于激活态，则保持其处于激活态。其中第一信息和第二信息可以分别发送或携带在同一个信息中发送。又比如，第二信息可以包含第三定时器的超时时间，接入网设备通过第二信息配置第三定时器的超时时间为第三时长，则第三定时器计时器超时时，终端设备将第一带宽部分切换至第二带宽部分。示例性的，终端设备UE本来在BWP1上传输数据，当确定BWP1上无数据传输或者持续预定时长无数据传输时，终端设备开启第三定时器，当第三定时器超时时，终端设备回退到BWP0(BWP0是接入网设备配置的默认BWP；如果接入网设备没有配置默认BWP，那么BWP0指接入网设备配置的初始BWP)。BWP状态切换和BWP切换往往是结合的，示例性，终端设备在BWP1上根据第三定时器超时，判断终端设备要从BWP1切换到BWP0，终端设备在BWP1上还要接收控制BWP状态切换的第一信息，如WUS，判断BWP1的状态如何切换。具体的，终端设备在BWP1上传输数据时BWP1处于激活态，当BWP1上无数据传输时，终端设备开启第三定时器，当第三定时器超时时，终端设备将会回退到BWP0。当第三定时器超时时，或者，在第三定时器超时之前，终端设备在BWP1上检测到WUS，如果WUS检测结果表示BWP1的状态需要切换，那么BWP1的状态从激活态切换为休眠态，并且，终端设备从BWP1切换到BWP0。当第三定时器超时时，或者，在第三定时器超时之前，终端设备在BWP1上检测WUS，如果WUS检测结果表示BWP1的状态不需要切换，那么BWP1的状态保持为激活态，并且，终端设备从BWP1切换到BWP0。再比如，第一信息包含第一定时器的超时时间，第二定时器包含第三定时器的超时时间，如第一信息包含第一定时器的超时时间timer1(第一时长)，第二信息包含第三定时器的超时时间timer3(第三时长)；则，终端设备根据第三定时器超时，从BWP1切换到BWP0。终端设备根据第一定时器超时，将BWP1从激活态切换至休眠态。其中，第一定时器和第三定时器均从BWP1进入激活态启动，或者第一定时器和第三定时器均从BWP1上确定无数据传输或者持续预定时长无数据传输时启动。另外，timer1可以大于timer3，这样，当第三定时器超时后，从BWP1切换到BWP0，BWP1仍然保持一段时间为激活态，之后第一定时器超时后，BWP1从激活态切换至休眠态。Timer1的值可以和timer3的值有关联关系，例如，Timer1的值等于Timer3的值，那么终端在切换BWP的同时将BWP的状态进行了转换。或者，可以是终端设备收到用于指示带宽部分切换的第二信息(当然该第二信息可以包含指示带宽部分切换的信息)后启动该第三定时器，在第三定时器超时时，对BWP切换。
示例性的，第一状态为第一带宽部分开启部分功能的状态，第二状态为第一带宽部分开启全部功能的状态时，终端设备从接入网设备接收第三信息；根据第三信息确定从第二带宽部分切换至第一带宽部分。
比如，终端设备在BWP2上接收到了接入网设备发送的第三信息，如，RRC信令，或者，MAC-CE信令，或者DCI信令，在配置的第三信息中包括了一个BWP的标识，比如BWP ID＝1，那么终端设备将从BWP2切换到BWP1，意味着，终端设备将在BWP1上传输数据。此时，通常会结合BWP1的状态切换，则终端设备在BWP1上接收到了 接入网设备发送的第一信息，如，RRC信令，或者，MAC-CE信令，或者DCI信令，在配置的第一信息中包括了一个BWP的标识，比如BWP ID＝1，则意味着，终端设备将在BWP1上传输数据，则接入网设备发送的第一信息指示了BWP1的状态切换为激活态，则无论BWP1当前处于何种状态(例如可以是休眠态或者去激活态或者激活态)，都需要将BWP1的状态切换为激活态，当然，若BWP1本身处于激活态，则保持其处于激活态。另外，将BWP2从激活态切换至休眠态，其中第一信息和第三信息可以分别发送或携带在同一个信息中发送。
一种可能的方式中，上述第一信息的形式可以为唤醒指示(wake up signal，WUS)，示例性的：WUS的形式可以是信令，如DCI信令，介质访问控制信元(medium access control-CE，MAC-CE)信令或无线资源控制(radio resource control，RRC)信令。
比如，DCI中的信息指示了BWP需要切换状态或不需要切换状态，例如，可以是1bit的信息，也可以是多于1个bit的信息，本申请中对信息的形式不作限定；可选的，参照上述的示例DCI中还可以通过若干bit指示BWP的标识。又比如，MAC-CE中有1个bit指示了BWP需要切换状态或不需要切换状态，或者MAC-CE中有若干个bit指示了BWP的状态；可选的，参照上述的示例MAC-CE中还可以通过若干bit指示BWP的标识。再比如，RRC中有1个bit指示了BWP需要切换状态或不需要切换状态，或者RRC中有若干个bit指示了BWP的状态；可选的，参照上述的示例RRC中还可以通过若干bit指示BWP的标识。
此外，第一信息还可以是其他的形式，例如可以是序列或者导频。
比如，第一信息可以是序列形式的WUS，而序列可以是如ZC(Zadoff-chu)序列，或者，最长线性移位寄存器序列(简称，m序列)。
比如，根据ZC序列的掩码监测结果，指示BWP是否需要切换状态。具体来说，终端设备通过检测ZC序列，可以检测出来具体的掩码结果，协议可以定义掩码1对应的是BWP需要切换状态，掩码2对应的是BWP不需要切换状态。那么，如果终端设备通过ZC序列检测到了掩码1，则BWP的状态需要切换。
或者比如，可以是导频形式的WUS，而导频比如可以是如CSI-RS、跟踪参考信号(tracking reference signals，TRS)、或者DMRS等。
比如，根据CSI-RS是否存在，指示BWP是否需要切换状态。一种可能的方式中，接入网设备通过RRC信令(或者，RRC信令再结合DCI信令，或者，RRC信令再结合MAC-CE信令，等等)为终端设备配置了至少一种CSI-RS配置信息。CSI-RS配置信息中至少包括以下一种：CSI-RS的图样信息，CSI-RS的时域信息，CSI-RS的频域信息，CSI-RS的功率信息等等。终端设备根据CSI-RS配置信息检测CSI-RS，如果检测到了CSI-RS(比如，可以根据检测CSI-RS的电平判断检测到了CSI-RS，或者，根据检测的CSI-RS的自相关性判断检测到了CSI-RS)，那么意味着BWP需要切换状态。如果没有检测到CSI-RS，那么意味着BWP不需要切换状态。又比如，WUS是在一个激活态的BWP上被终端设备接收到的，因此，这个WUS需要指示出：哪个BWP、是否需要切换状态。比如，CSI-RS的图样编号可以和BWP ID有关联关系，再根据是否可以检测出来CSI-RS，来确定该BWP是否需要切换状态。示例性的，BWP1的状态已处于休眠态，终端设备在BWP0上传输数据。终端设备在BWP0上接收到了接入 网设备发送的第一信息，例如，形式为CSI-RS的WUS。接入网设备为终端设备配置了多种CSI-RS图样，比如图样1、2、3，每种图样代表了一种特定的时频资源，终端设备分别在图样1、2、3所指示的时频资源上检测CSI-RS。如果终端设备在图样1所指示的时频资源上检测到了CSI-RS，那么终端设备根据图样1确定BWP ID。图样标识和BWP标识的对应关系可以是协议预定义的，例如，图样标识等于BWP标识。UE在图样1上检测到了CSI-RS意味着BWP1的状态需要切换，相当于BWP1的状态从休眠态切换为去激活态。此外，第二信息以及第三信息的形式也可以为WUS，具体功能可以参照上述第一信息的描述不再赘述。
此外，上述实施例提供的方案适用于下行BWP、上行BWP，还可以适用于边链路BWP(sidelink BWP)，本申请的实施例不做限定。对上行BWP或下行BWP或边链路BWP，终端设备可能在不同的载波上各支持一个激活的BWP，也可以在所有载波上只支持一个激活的BWP。例如，对上行BWP，终端设备可能在不同的上行载波上各支持一个激活的上行BWP，也可以在所有上行载波上只支持一个激活的上行BWP，对于下行BWP、边链路BWP的情况与上行BWP类似。
对于支持补充上行链路(supplementary uplink，SUL)的终端设备来说，在普通上行链路(normal UL，简称为UL)载波上可以包含了该载波上的1个或多个上行BWP，在SUL载波上，可以包含了该载波上的1个或多个上行BWP。假如一个终端设备只能支持一个激活的上行BWP，那么UE可以在UL上的激活上行BWP上发送上行数据，而SUL上的上行BWP需要被切换为休眠态，休眠态的上行BWP上终端设备可以发送SRS或者进行测量。该休眠态的BWP可以是根据控制BWP切换的信息而切换了状态，例如，终端设备根据切换BWP的信息(可以为定时器的时长或者具体的指示BWP切换的信息)从SUL上的上行BWP切换到UL上的上行BWP上，那么SUL上的上行BWP的状态切换到休眠态，UL上的上行BWP的状态切换为激活态。该休眠态的BWP也可以是根据指示状态切换的信息切换了状态，例如，终端设备根据DCI信令或者MAC-CE信令或者RRC信令或者WUS，将SUL上的上行BWP的状态切换为休眠态。以上仅是一种示例，切换上行BWP的的具体方法和上文所述的切换BWP的方法一致，不再赘述。切换上行BWP的状态的具体方法和上文所述的切换BWP的状态的方法一致，不再赘述。以上仅以上行BWP为例进行说明，下行BWP以及边链路BWP也是类似的。在一些实施例中，控制切换BWP的信息可以是控制切换上行BWP的信息(例如定时器时长)，也可以是控制切换下行BWP的信息；控制切换上行BWP的状态的信息可以是控制切换上行BWP的状态的信息，即上行BWP及下行BWP采用同一个信息控制BWP的切换，上行BWP及下行BWP采用同一个信息控制BWP的状态的切换。
在一些实施例中，为了降低终端设备的功耗，可以为终端设备只保留一个处于休眠态的带宽部分或者只保留一个处于激活态的带宽部分。例如：当第一带宽部分进入休眠态时，可以将该UE的其他带宽部分切换至去激活态；或者，当第一带宽部分进入激活态时，将该UE的其他带宽部分切换至去激活态。
一种可能的方式中，在同一个小区或者同一中心频点下至少存在两个不同的带宽部分的场景下：当第一带宽部分进入休眠态时，可以将与第一带宽部分同一个小区或 者同一个中心频点下的其他处于休眠态的带宽部分切换至去激活态；或者，当第一带宽部分进入激活态时，可以将与第一带宽部分同一个小区或者同一个中心频点下的其他处于激活态的带宽部分切换至去激活态。
示例性的，终端设备在3个BWP上依次切换，例如：当终端设备从BWP1切换到BWP2时，BWP1切换至休眠态，BWP2切换至激活态，BWP3为去激活态。然后，当终端设备从BWP2切换到BWP3时，可能造成的场景是：BWP1仍为休眠态，BWP2的状态切换为休眠态，BWP3切换为激活态。这时，BWP1和BWP2均为休眠态。则，当同一个小区或同一个频点上有多于1个BWP处于休眠态时，将除最新切换为休眠态的BWP之外的其他休眠态BWP切换为去激活态。这意味着，BWP1的状态需要从休眠切换为去激活，这样，3个BWP的状态分别为：去激活态、休眠态、激活态。当然，由于BWP1-3都是同一个终端设备的，并且终端设备可以判断并决定每个BWP的状态。
在另一个示例中，如果BWP是根据第二定时器超时从休眠态切换为去激活态，那么在将其他休眠态的BWP切换为去激活态时，需要停止处于休眠态的BWP对应的第二定时器，并重置第二定时器。相当于，只保留1个休眠态的BWP。例如：BWP从休眠态切换为去激活态是根据上述的第二定时器超时而确定的。这个第二定时器是per BWP(即针对每个BWP单独配置第二定时器)配置的，即每个BWP对应的第二定时器的超时时长可以相同或者不同。如图9所示，在终端设备从BWP1切换至BWP2时，BWP1从激活态切换至休眠态，并启动BWP1的第二定时器；BWP2从休眠态或者去激活态切换至激活态；然后终端设备从BWP2切换至BWP3，则BWP2从激活态切换至休眠态，并启动BWP2的第二定时器；BWP3从休眠态或者去激活态切换至激活态；此时，若BWP1的第二定时器还未超时，则BWP1、2、3分别为：休眠态、休眠态、激活态，BWP1的第二定时器仍在计时，BWP2的第二定时器仍在计时。那么，终端将BWP1的状态从休眠态切换为去激活态时，还要将BWP1的第二定时器停止，或者，停止并重置。这样的话，BWP1的状态为去激活。BWP2的第二定时器还在计时，所以BWP2的状态为休眠态，BWP3的状态为激活态，从而降低了终端设备的功耗。
在另外一个示例中，如果BWP是根据第一定时器从激活态切换为休眠态，那么终端设备在将其他激活态的BWP切换为去激活态时，需要停止处于激活态的BWP对应的第一定时器，并重置第一定时器。相当于，禁止其他BWP进入休眠态，也相当于只保留1个休眠态的BWP。
BWP从激活态切换为休眠态是根据上述的第一定时器超时而确定的。这个第一定时器是per BWP(即针对每个BWP单独配置第一定时器)配置的，即每个BWP对应的第一定时器的超市时长可以相同或者不同。例如，如图10所示，BWP可以根据第一定时器的控制而离开激活态，那么终端设备离开BWP1时(例如终端设备从BWP1切换到BWP2)，BWP1的状态可能还会为激活态直至BWP1的第一定时器超时。这可能会造成：终端设备在将BWP1的状态切换至激活态时，启动BWP1的第一定时器，终端设备将切换BWP从BWP2切换至BWP3，BWP3的状态切换至激活态，则BWP2的状态也需要根据BWP2的第一定时器是否超时来判断合适离开激活态，例如，切换 至休眠态。则当BWP1的第一定时器以及BWP2的第一定时器均未超时时，BWP1、2、3分别为：激活态、激活态、激活态，BWP1的第一定时器在计时，BWP2的第一定时器也在计时，终端设备在BWP3上传输数据。那么，终端设备将BWP1和BWP2的状态从激活态直接切换为去激活态，并且，终端设备将BWP1和BWP2的第一定时器停止，或者，停止并重置。这样的话，相当于禁止多余1个BWP(BWP1、2)处于激活态，也相当于，禁止BWP1、2进入休眠态，直接将BWP1、2切换为去激活态，所以BWP1、2的状态为去激活态，BWP3的状态为激活态，从而降低了终端设备的功耗。
又比如：如图11所示，BWP可以根据第一定时器的控制而离开激活态，那么终端设备离开BWP1时(例如终端设备从BWP1切换到BWP2)，BWP1的状态可能还会为激活态直至BWP1的第一定时器超时。终端设备在将BWP1的状态切换至激活态时，启动BWP1的第一定时器，终端设备将切换BWP从BWP2切换至BWP3时，BWP3的状态切换至激活态，则BWP2的状态也需要根据BWP2的第一定时器是否超时来判断合适离开激活态，例如，切换至休眠态。则当BWP1的第一定时器以及BWP2的第一定时器均未超时时，若BWP2的第一定时器先超时，则BWP2进入休眠态，并且启动BWP2的第二定时器，此时BWP1、2、3分别为：激活态、休眠态、激活态，BWP1的第一定时器在计时，BWP2的第二定时器也在计时，终端设备在BWP3上传输数据。那么，终端设备将BWP1的状态从激活态直接切换为去激活态，并且，终端设备将BWP1的第一定时器停止，或者，停止并重置。这样的话，相当于禁止多余1个BWP(BWP1)处于激活态，也相当于，禁止BWP1进入休眠态，直接将BWP1切换为去激活态，所以BWP2的状态为休眠态，BWP3的状态为激活态，从而降低了终端设备的功耗。
