Description

一种数据传输、BWP切换方法及设备
本申请要求在2018年9月28日提交中国专利局、申请号为201811139719.8、申请名称为“一种数据传输、BWP切换方法及设备”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
本申请涉及通信技术领域，尤其涉及一种数据传输、BWP切换方法及设备。
背景技术
在第三代合作伙伴计划(3 rd generation partnership project，3GPP)完成的第五代移动通信技术(the 5 th generation，5G)新无线(new radio，NR)系统中，引入了带宽部分(bandwidth part，BWP)的概念。BWP的引入，有引于控制终端设备的成本和功耗，是5G中的关键技术。在终端设备的性能、成本和灵活性之间，通过BWP的概念可以进行灵活的配置和处理，使得5G系统在带宽的配置上非常灵活。
现有技术中，对于一个终端设备，在用于蜂窝链路的每个载波上可以配置最多4个BWP，同一时刻，在一个载波上只能激活一个BWP。如果终端设备从当前工作的BWP切换到另一个BWP，因为需要进行射频(radio frequency，RF)参数的重配置，因此会产生一定的RF中断时间，无法保证通信的质量和可靠性。
发明内容
本申请实施例提供一种数据传输、BWP切换方法及设备，用于减少甚至消除RF中断时间，提高通信质量。
第一方面，提供第一种数据传输方法，该方法包括：发送第一BWP和第二BWP的配置信息，所述第一BWP的中心频率与所述第二BWP的中心频率相同，所述第一BWP的带宽与所述第二BWP的带宽相同；在所述第一BWP上传输数据。
该方法可由第一通信装置执行，第一通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置，例如第一通信装置为网络设备，当然还可以是其他通信装置，例如芯片系统。
例如，一种实现方式为，第一BWP占用的频域资源和第二BWP占用的频域资源相同，这样，第一BWP和第二BWP的中心频率就会相同，带宽也相同。在本申请实施例中，配置的第一BWP和第二BWP的中心频率相同，而且带宽相同，那么如果要从第一BWP切换到第二BWP，是无需进行RF切换的，因此可以减少甚至消除RF中断时间，使得通信过程可以连续，提高了通信的质量和可靠性。
结合第一方面，在第一方面的一种可能的实现方式中，所述方法还包括：确定终端设备需要切换BWP传输时，从所述第一BWP切换到所述第二BWP上传输数据。终端设备从第一BWP切换到第二BWP时，由于无需临时再对第二BWP进行RF参数重配置，因此可以减少甚至消除RF中断时间，使得通信过程可以连续，可以提高通信的质量和可靠性。
结合第一方面，在第一方面的一种可能的实现方式中，所述第一BWP和/或所述第二BWP为激活的BWP。
第一BWP可以是激活的BWP，或者第二BWP是激活的BWP，或者第一BWP和第二BWP均为激活的BWP。也就是本申请实施例中，在一个载波上可以同时激活一个BWP，也可以同时激活两个BWP，如果同时激活两个BWP，则终端设备无需在这两个BWP之间切换就能实现在这两个BWP上传输数据，消除了RF中断时间，提高了通信过程的连续性。
结合第一方面，在第一方面的一种可能的实现方式中，所述第一BWP的子载波间隔与所述第二BWP的子载波间隔相同或不同。
如果第一BWP的子载波间隔和第二BWP的子载波间隔相同，则可以认为第一BWP和第二BWP是同一个BWP，例如第一BWP用于sidelink，第二BWP用于蜂窝链路，也就是同一个BWP既可以用于sidelink也可以用于蜂窝链路，从而终端设备无需在第一BWP和第二BWP之间切换，消除了因切换带来的时延。或者，如果第一BWP和第二BWP的子载波间隔不同，而第一BWP和第二BWP从终端设备的RF模块来看，中心频率一样，带宽大小一样，因此即使重新配置第一BWP和/或第二BWP的除了中心频率和带宽之外的其它参数，终端设备在第一BWP和第二BWP之间进行切换时，也并不会因BWP的切换导致终端设备的RF模块的重调，从而产生中断。因此终端设备如果要从第一BWP切换到对应的第二BWP，或者从第二BWP切换到对应的第一BWP，基本可以实现零时延的切换，也就是终端设备基本可以在没有任何中断的条件下在2个BWP之间实现无缝的切换，从而达成了无中断高质量通信的目标，同时也获得了BWP的低成本、低功率消耗的优点。
结合第一方面，在第一方面的一种可能的实现方式中，所述方法还包括：接收终端设备的能力信息，所述终端设备的能力信息用于指示所述终端设备是否支持同时激活至少两个BWP。
终端设备可以事先将终端设备的能力信息发送给网络设备，从而网络设备就可以明确终端设备是否支持同时激活至少两个BWP，使得最终激活的BWP的数量符合终端设备的实际能力。
结合第一方面，在第一方面的一种可能的实现方式中，若所述终端设备具有第一类能力，则同时激活所述第一BWP和所述第二BWP；或，若所述终端设备具有第二类能力，则在所述第一BWP和所述第二BWP中只激活一个BWP。
如果终端设备具有第一类能力，表明终端设备是支持同时激活至少两个BWP的，那么可以同时激活第一BWP和第二BWP，或者可以同时激活第一BWP或第二BWP，也就是，如果终端设备支持同时激活至少两个BWP，则可以同时激活一个BWP、两个BWP或更多个BWP。而如果终端设备具有第二类能力，表明终端设备不支持同时激活至少两个BWP，则只能同时激活一个BWP。
结合第一方面，在第一方面的一种可能的实现方式中，所述方法还包括：所述配置信息用于配置所述第一BWP和所述第二BWP，其中，所述第一BWP与所述第二BWP的频域资源相同，所述配置信息包括：用于所述第一BWP和所述第二BWP的公共配置信息；用于所述第一BWP上进行数据传输的配置信息；用于所述第二BWP上进行数据传输的配置信息。
配置信息是用于配置第一BWP和第二BWP的，因此配置信息中可以包括公共配置信息，公共配置信息包括的信息既能用于第一BWP，也能用于第二BWP，通过公共配置信 息的方式来实现，有助于减少配置信息的信息量。例如公共配置信息可以包括如下信息中的至少一种：子载波间隔，CP类型，BWP的带宽，或BWP的标识。当然公共配置信息包括的信息不限于此。另外配置信息中还包括对应于第一BWP的配置信息和对应于第二BWP的配置信息。
结合第一方面，在第一方面的一种可能的实现方式中，所述方法还包括：所述配置信息用于配置所述第一BWP和所述第二BWP，其中，所述第一BWP与所述第二BWP为同一个BWP，所述配置信息包括：用于侧行链路和蜂窝链路的公共配置信息；用于所述侧行链路上进行数据传输的配置信息；用于所述蜂窝链路上进行数据传输的配置信息。
如果第一BWP和第二BWP是同一个BWP，那么该BWP可以用于传输侧行链路，也可以用于传输蜂窝链路，因此配置信息中可以包括公共配置信息，公共配置信息包括的信息既能用于蜂窝链路，也能用于侧行链路，通过公共配置信息的方式来实现，有助于减少配置信息的信息量。例如公共配置信息可以包括如下信息中的至少一种：子载波间隔，CP类型，BWP的带宽，或BWP的标识。当然公共配置信息包括的信息不限于此。另外配置信息中还包括对应于蜂窝链路的配置信息和对应于侧行链路的配置信息。
结合第一方面，在第一方面的一种可能的实现方式中，所述公共配置信息包括以下至少一项：子载波间隔，循环前缀CP类型，BWP带宽，或BWP的标识。
结合第一方面，在第一方面的一种可能的实现方式中，所述第一BWP用于侧行链路，所述第二链路用于蜂窝链路，所述侧行链路在所述第一BWP上的传输资源与所述蜂窝链路在第二BWP上的传输资源是时分复用和/或频分复用。
如果第一BWP和第二BWP是同一个BWP，例如第一BWP用于侧行链路，第二BWP用于蜂窝链路，也就是同一个BWP既可以用于侧行链路也可以用于蜂窝链路，那么可以使得侧行链路在第一BWP上的传输资源与蜂窝链路在第二BWP上的传输资源是时分复用，或者使得侧行链路在第一BWP上的传输资源与蜂窝链路在第二BWP上的传输资源是频分复用，或者使得侧行链路在第一BWP上的传输资源与蜂窝链路在第二BWP上的传输资源是时分复用和频分复用，这样可以减少链路之间的干扰。
结合第一方面，在第一方面的一种可能的实现方式中，所述第一BWP和所述第二BWP均属于BWP集合，所述BWP集合是为蜂窝链路配置的BWP的集合。
第一BWP和第二BWP均可以属于BWP集合，BWP集合可以是为蜂窝链路所配置的BWP集合，从而无需再为侧行链路单独配置BWP集合。例如BWP集合中包括了一个载波上的4个BWP，也就是在该载波上为蜂窝链路配置了4个BWP集合，那么这4个BWP可以理解为4个第二BWP，例如可以为这4个第二BWP中的至少一个BWP再配置对应的第一BWP，例如可以为这4个第二BWP中的1个、2个、3个或4个BWP再分别配置对应的第一BWP，那么对于该载波而言，配置的第一BWP的数量可以是1、2、3或4。这些第一BWP和第二BWP都属于该BWP集合。
结合第一方面，在第一方面的一种可能的实现方式中，所述方法还包括：发送第一消息，所述第一消息用于配置所述第一BWP，所述第一消息包括以下至少一项：所述第一BWP的标识，所述第一BWP的子载波间隔，与所述第一BWP对应的所述第二BWP的标识，或，所述第一BWP的带宽。
如果认为第一BWP和第二BWP是具有对应关系的一对BWP，那么，如果第一BWP和第二BWP不是同一个BWP，例如网络设备通过一条消息为终端设备配置第一BWP， 该消息例如称为第一消息，网络设备将第一消息发送给终端设备，则终端设备接收来自网络设备的第一消息。第一消息可以包括如下的至少一种：第一BWP的标识，第一BWP的子载波间隔，与第一BWP对应的第二BWP的标识，或第一BWP的带宽。例如第一消息可以包括与第一BWP对应的第二BWP的标识，也就是，第一消息虽然是配置第一BWP，但是第一消息中也可以包括对应的第二BWP的标识，从而通过第一消息就可以指示与第一BWP对应的第二BWP。或者，第一消息中也可以不包括与第一BWP对应的第二BWP的标识，则第一消息可以认为是专用于配置第一BWP，而第一BWP和第二BWP之间的对应关系，或者说与第一BWP对应的第二BWP的信息，可以通过其他方式指示，例如再通过另外的消息包括与第一BWP对应的第二BWP的标识。
结合第一方面，在第一方面的一种可能的实现方式中，所述方法还包括：在所述第一BWP上发送第一调度信息，所述第一调度信息用于调度所述第二BWP上的第一链路的数据传输。
结合第一方面，在第一方面的一种可能的实现方式中，所述方法还包括：在所述第二BWP上发送第二调度信息，所述第二调度信息指示第一BWP上的第二链路和/或第三链路的数据传输。
在一个BWP上既可以调度本BWP上的链路的数据传输，也可以调度对应的另一个BWP上的链路的数据传输，较为灵活。
结合第一方面，在第一方面的一种可能的实现方式中，所述第一调度信息指示所述第二BWP的标识；所述第二调度信息指示所述第一BWP的标识。
在跨BWP调度时，可以指示所调度的BWP的标识，以明确究竟调度的是哪个BWP，提高调度的准确性。

第二方面，提供第二种数据传输方法，该方法包括：确定配置的第一BWP和第二BWP，所述第一BWP的中心频率与所述第二BWP的中心频率相同，所述第一BWP的带宽与所述第二BWP的带宽相同；在所述第一BWP上传输数据。
该方法可由第二通信装置执行，第二通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置，例如第二通信装置为终端设备，当然还可以是其他通信装置，例如芯片系统。
结合第二方面，在第二方面的一种可能的实现方式中，所述方法还包括：确定需要切换BWP传输时，从所述第一BWP切换到所述第二BWP上传输数据。

结合第二方面，在第二方面的一种可能的实现方式中，所述方法还包括：向所述网络设备发送终端设备的能力信息，所述终端设备的能力信息用于指示所述终端设备是否支持 同时激活至少两个BWP。
结合第二方面，在第二方面的一种可能的实现方式中，所述方法还包括：接收配置信息，所述配置信息用于配置所述第一BWP和所述第二BWP，其中，所述第一BWP与所述第二BWP的频域资源相同，所述配置信息包括：用于所述第一BWP和所述第二BWP的公共配置信息；用于所述第一BWP上进行数据传输的配置信息；用于所述第二BWP上进行数据传输的配置信息。
结合第二方面，在第二方面的一种可能的实现方式中，所述方法还包括：接收配置信息，所述配置信息用于配置所述第一BWP和所述第二BWP，其中，所述第一BWP与所述第二BWP为同一个BWP，所述配置信息包括：用于侧行链路和蜂窝链路的公共配置信息；用于所述侧行链路上进行数据传输的配置信息；用于所述蜂窝链路上进行数据传输的配置信息。

结合第二方面，在第二方面的一种可能的实现方式中，所述方法还包括：在所述第二BWP上接收第二调度信息，所述第二调度信息指示第一BWP上的第二链路和/或第三链路的数据传输。

关于第二方面或第二方面的各种可能的实现方式所带来的技术效果，可参考对于第一方面或第一方面的各种可能的实现方式的技术效果的介绍，不多赘述。
第三方面，提供第一种BWP切换方法，该方法包括：在第一BWP上发送第一切换指示信息，所述第一切换指示信息用于指示终端设备切换到第三BWP；确定所述第一BWP的优先级和/或第二BWP的优先级；若所述第二BWP的优先级低于所述第一BWP的优先级，确定所述终端设备从所述第一BWP切换到所述第三BWP。
该方法可由第三通信装置执行，第三通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置，例如第三通信装置为网络设备，当然还可以是其他通信 装置，例如芯片系统。
终端设备在切换BWP时，可能会对其他的BWP造成影响，因此终端设备在切换时可以判断BWP的优先级，如果其他BWP的优先级低于待切换的BWP的优先级，则终端设备可以进行切换，因为切换过程虽然可能对第二BWP造成影响，但鉴于第二BWP或第二BWP上传输的业务不是特别重要，所以可以接受这种影响。
结合第三方面，在第三方面的一种可能的实现方式中，所述第一BWP的优先级包括所述第一BWP的优先级和/或所述第一BWP上传输的数据的优先级，所述第二BWP的优先级包括所述第二BWP的优先级和/或所述第二BWP上传输的数据的优先级。
对于第一BWP来说，第一BWP的优先级可以是第一BWP本身的优先级，也就是BWP的优先级，或者也可以是第一BWP上传输的数据的优先级，或者可以是第一BWP的优先级和第一BWP上传输的数据的优先级，对于第二BWP来说也是同样的。
结合第三方面，在第三方面的一种可能的实现方式中，若所述第二BWP的优先级高于第一门限，则确定所述终端设备不将所述第一BWP切换到第三BWP，或者确定所述终端设备延迟将所述第一BWP切换到所述第三BWP。
如果第二BWP的优先级较高，则终端设备可以不进行切换，或者可以延迟进行切换，以尽量减小因切换造成的对优先级较高的BWP的影响。
结合第三方面，在第三方面的一种可能的实现方式中，在指示所述终端设备将所述第二BWP切换到所述第三BWP之后，所述方法还包括：指示所述终端设备重传在将所述第一BWP切换到所述第三BWP的过程中，在所述第二BWP上传输的至少一个数据包；或，向所述终端设备重传在将所述第一BWP切换到所述第三BWP的过程中，在所述第二BWP上传输的至少一个数据包。
结合第三方面，在第三方面的一种可能的实现方式中，所述在第一BWP上传输的至少一个数据包为受第二BWP切换中断影响的数据包。
如果终端设备进行了切换，那么在切换过程中可能导致了第二BWP上的传输的中断，因此在终端设备切换到第三BWP后，可以指示终端设备重传在切换过程中在第二BWP上传输的数据包，以尽量降低对于第二BWP的影响，减小丢包率。
结合第三方面，在第三方面的一种可能的实现方式中，所述方法还包括：
在所述第二BWP上发送第二切换指示消息，所述第二切换指示信息用于指示切换到第四BWP；

所述终端设备为第二能力，确定所述终端设备同时将所述第一BWP切换到所述第三BWP，以及将所述第二BWP切换到所述第四BWP。
如果终端设备分别要进行两个BWP的切换，那么终端设备可以按照优先级，先切换高优先级的BWP再切换低优先级的BWP，或者终端设备也可以根据终端设备的实际能力来切换，如果终端设备为第一能力，表明终端设备只支持一个BWP的切换，则终端设备可以选择其中的一个切换过程，而如果终端设备为第二能力，表明终端设备可以支持两个BWP的切换，则终端设备可以完成两个切换过程。
结合第三方面，在第三方面的一种可能的实现方式中，所述方法还包括：接收所述终端设备的能力信息，所述终端设备的能力信息用于指示所述终端设备是否支持同时将至少两个BWP分别切换到其他的BWP，和/或，所述终端设备在将一个BWP切换到另一个BWP时是否会影响所述终端设备其他BWP的工作。
终端设备可以先向网络设备发送终端设备的能力信息，从而网络设备可以根据终端设备的能力信息来指示终端设备的工作。
结合第三方面，在第三方面的一种可能的实现方式中，所述第一BWP用于侧行链路，所述第二链路用于蜂窝链路；或者所述第一BWP用于蜂窝链路，所述第二BWP用于侧行链路。

结合第四方面，在第四方面的一种可能的实现方式中，在将所述第二BWP切换到所述第三BWP之后，所述方法还包括：重传在将所述第一BWP切换到所述第三BWP的过程中，在所述第二BWP上传输的至少一个数据包。
结合第四方面，在第四方面的一种可能的实现方式中，所述在第一BWP上传输的至少一个数据包为受第二BWP切换中断影响的数据包。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。

作为示例而非限定，在本申请实施例中，该终端设备还可以是车载终端设备，或者可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如： 智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能头盔、智能首饰等。
2)网络设备，例如包括接入网(access network，AN)设备，例如基站(例如，接入点)，可以是指接入网中在空口通过一个或多个小区与无线终端设备通信的设备。网络设备可用于将收到的空中帧与网际协议(IP)分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。网络设备还可协调对空口的属性管理。例如，网络设备可以包括长期演进(long term evolution，LTE)系统或演进的LTE系统(LTE-Advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括5G NR系统中的下一代节点B(next generation node B，gNB)或者也可以包括云接入网(cloud radio access network，CloudRAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，本申请实施例并不限定。
3)载波带宽部分(carrier bandwidth part)，可以是频域上一段连续的资源，载波带宽部分还可以称为也可称为带宽部分(bandwidth part，BWP或BP)、子带、子带(subband)带宽、窄带或窄带(narrowband)带宽，或者还可以有其他的名称，本申请实施例对载波带宽部分的名称不做限定，在本文中，为了简便，以名称是BWP为例。例如，一个BWP包含连续的K(K>0)个子载波；或者，一个BWP为N个不重叠的连续的资源块(resource block，RB)所在的频域资源，该RB的子载波间隔可以为15KHz、30KHz、60KHz、120KHz、240KHz、480KHz或其他值；或者，一个BWP为M个不重叠的连续的资源块组(resource block group，RBG)所在的频域资源，一个RBG包括P(P>0)个连续的RB，该RB的子载波间隔(subcarrier spacing，SCS)可以为15KHz、30KHz、60KHz、120KHz、240KHz、480KHz或其他值，例如为2的整数倍。一个BWP与一个特定的系统参数(numerology)相关，所述系统参数包括子载波间隔、循环前缀(cyclic prefix，CP)、或子载波间隔和CP。进一步地，载波带宽部分还可以是频域上非连续的多段资源。

载波带宽部分是一个自包含的结构，例如，终端设备不期望在下行载波带宽部分之外的其他带宽进行下行接收，不期望在上行载波带宽部分之外的其他上行带宽进行上行发送。
4)本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上，鉴于此，本申请实施例中也可以将“多个”理解为“至少两个”。“至少一个”，可理解为一个或多个，例如理解为一个、两个或更多个。例如，包括至少一个，是指包括一个、两个或更多个，而且不限制包括的是哪几个。例如，包括A、B和C中的至少一个，那么包括的可以是A、B、C，A和B，A和C，B和C，或A和B和C。或者例如，配置至少一个，是指配置一个、两个、或更多个，例如配置至少一个BWP，可以理解为配置一个BWP、配置两个BWP或者配置更多个BWP。同理，对于“至少一种”等描述的理解，也是类似的。“和/或”，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。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。
除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词用于对多个对象进 行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如第一BWP和第二BWP，只是为了区分不同的BWP，并不是限制这两个BWP的优先级或重要程度等。
首先，介绍本申请实施例中涉及的技术特征。
在3GPP完成的5G NR系统中，引入了BWP的概念。BWP的引入，有引于控制终端设备的成本和功耗，是5G中的关键技术。在终端设备的性能、成本和灵活性之间，通过BWP的概念可以进行灵活的配置和处理，使得5G系统在带宽的配置上非常灵活。
然而凡事有利必有弊，BWP也不特外。对于一个终端设备，在用于蜂窝链路的每个载波上可以配置最多4个BWP，同一时刻，在一个载波上只能激活一个BWP。如果终端设备从当前工作的BWP切换到另一个BWP，因为需要进行RF参数的重配置，因此会产生一定的RF中断时间，无法保证通信的质量和可靠性。
如图1所示，BWP的切换大概包括几种场景，例如场景1为，变换BWP的中心频点，场景2为，变换BWP的带宽，但不变换BWP的中心频点，场景3为，同时变换BWP的中心频点和带宽。在这几种场景下，都需要进行RF参数的重配置，因此都会产生一定的RF中断时间。
另外，目前刚刚开始研究的5G车联网系统，正在讨论如何将BWP的概念和方法引入到车联网所在的侧行链路(sidelink)上。从而提高终端设备之间通信的效率和性能。然而，目前在进行BWP切换时会导致RF中断，如果将现有技术直接应用于sidelink的传输，则也会导致sidelink通信的中断，不能保证通信的质量和可靠性。sidelink有时也被称为设备到设备(device to device，D2D)链路，或者被称为边链路等，本申请实施例对于sidelink的名称不做限定。
鉴于此，提供本申请实施例的技术方案。在本申请实施例中，配置的第一BWP和第二BWP的中心频率相同，而且带宽相同，那么如果要从第一BWP切换到第二BWP，是无需进行RF切换的，因此可以减少甚至消除RF中断时间，使得通信过程可以连续，提高了通信的质量和可靠性。
本申请实施例提供的技术方案可以应用于5G系统，或者应用于未来的通信系统或其他类似的通信系统。另外，本申请实施例提供的技术方案可以应用于蜂窝链路，也可以应用于设备间的链路，例如设备到设备(device to device，D2D)链路。

下面结合附图介绍本申请实施例提供的技术方案。
本申请实施例提供一种数据传输方法，请参见图3A或图3B，为该方法的流程图。在下文的介绍过程中，以该方法应用于图2A或图2B所示的网络架构为例。另外，该方法可由两个通信装置执行，这两个通信装置例如为第一通信装置和第二通信装置，其中，第一通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置，或者第一通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片系统。对于第二通信装置也是同样，第二通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置，或者第二通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片系统。且对于第一通信装置和第二通信装置的实现方式均不做限制，例如第一通信装置可以是网络设备，第二通信装置是终端设备，或者第一通信装置和第二通信装置都是网络设备，或者第一通信装置和第二通信装置都是终端设备，或者第一通信装置是网络设备，第二通信装置是能够支持终端设备实现该方法所需的功能的通信装置，等等。其中，网络设备例如为基站。
为了便于介绍，在下文中，以该方法由网络设备和终端设备执行为例，也就是，以第一通信装置是网络设备、第二通信装置是终端设备为例。因为本实施例是以应用在图2A或图2B所示的网络架构为例，因此，如果将本实施例应用在图2A所示的网络架构，则下文中所述的网络设备可以是图2A所示的网络架构中的网络设备，下文中所述的终端设备可以是图2A所示的网络架构中的终端设备，或者，如果将本实施例应用在图2B所示的网络架构，则下文中所述的网络设备可以是图2B所示的网络架构中的网络设备，下文中所述的终端设备可以是图2B所示的网络架构中的第一终端设备或第二终端设备。
S31、网络设备向终端设备发送第一BWP和第二BWP的配置信息，终端设备接收来自网络设备的第一BWP和第二BWP的配置信息。第一BWP的中心频率与第二BWP的中心频率相同，第一BWP的带宽与第二BWP的带宽相同。
例如网络设备可以通过一条消息为终端设备一并配置第一BWP和第二BWP，或者网络设备也可以通过两条不同的消息为终端设备分别配置第一BWP和第二BWP，如果网络设备通过两条消息为终端设备分别配置第一BWP和第二BWP，则网络设备可以同时发送用于配置第一BWP的消息和用于配置第二BWP的消息，也就是同时配置第一BWP和第二BWP，或者网络设备可以先发送用于配置第一BWP的消息，后发送用于配置第二BWP的消息，也就是先配置第一BWP，再配置第二BWP，或者网络设备可以先发送用于配置第二BWP的消息，后发送用于配置第一BWP的消息，也就是先配置第二BWP，再配置第一BWP，具体的不做限制。
如果第一BWP和第二BWP不是同一个BWP，例如网络设备通过一条消息为终端设备配置第一BWP和第二BWP，该消息例如称为第一消息，第一消息包含配置信息，配置信息可以配置第一BWP和第二BWP。网络设备发送配置信息，终端设备接收来自网络设备的配置信息，则终端设备就可以确定网络设备所配置的第一BWP和第二BWP。那么该 配置信息可以包括三部分的内容，分别为第一部分、第二部分和第三部分，其中的第一部分包括用于第一BWP和第二BWP的公共配置信息，第二部分包括用于第一BWP上进行数据传输的配置信息，第三部分包括用于第二BWP上进行数据传输的配置信息。如果网络设备通过两条不同的消息分别为终端设备配置第一BWP和第二BWP，则用于配置第一BWP的消息中可以包括第一部分和第二部分，用于配置第二BWP的消息中可以包括第一部分和第三部分。
所谓的第一BWP和第二BWP的公共配置信息，例如公共配置信息包括的信息既能用于第一BWP，也能用于第二BWP。例如第一部分可以包括如下信息中的至少一种：子载波间隔，循环前缀(cyclic prefix，CP)类型，BWP的带宽，或BWP的标识。当然第一部分包括的信息不限于此。例如，如果第一BWP和第二BWP不是同一个BWP，则第一部分可以不包括BWP的标识，因为两个BWP不能共用同一个BWP的标识。另外，如果第一BWP和第二BWP的子载波间隔不同，那么第一部分还可以不包括子载波间隔，因为两个BWP并不是共用同一个BWP。第二部分包括的用于第一BWP上进行数据传输的配置信息，例如包括以下的至少一种：用于第一BWP上的数据信道的配置信息，用于第一BWP上的控制信道的配置信息，用于第一BWP上的参考信号(reference signal，RS)的配置信息，用于第一BWP上的波束管理的配置信息，或用于第一BWP上的功率控制信息的配置信息。当然用于第一BWP上进行数据传输的配置信息不限于此。第三部分包括的用于第二BWP上进行数据传输的配置信息，例如包括以下的至少一种：用于第二BWP上的数据信道的配置信息，用于第二BWP上的控制信道的配置信息，用于第二BWP上的RS的配置信息，用于第二BWP上的波束管理的配置信息，或用于第二BWP上的功率控制信息的配置信息。当然用于第二BWP上进行数据传输的配置信息不限于此。
或者，如果第一BWP和第二BWP是同一个BWP。例如网络设备通过一条消息为终端设备配置第一BWP和第二BWP，该消息例如称为第二消息，第二消息包含配置信息，配置信息可以配置第一BWP和第二BWP。网络设备发送配置信息，终端设备接收来自网络设备的配置信息，则终端设备就可以确定网络设备所配置的第一BWP和第二BWP。该配置信息也可以包括三部分的内容，分别为第一部分、第二部分和第三部分，这里的第一部分与上文中所述的第一部分是不同的，这里的第二部分与上文中所述的第二部分是不同的，这里的第三部分与上文中所述的第三部分是不同的。以第一BWP是用于sidelink的BWP、第二BWP是用于蜂窝链路的BWP为例，那么，这里的第一部分可以包括用于第一BWP上的侧行链路和用于第二BWP上的蜂窝链路的公共配置信息，第二部分包括用于第一BWP上的侧行链路上进行数据传输的配置信息，第三部分包括用于第二BWP上的蜂窝链路上进行数据传输的配置信息。如果网络设备通过两条不同的消息分别为终端设备配置第一BWP和第二BWP，则用于配置第一BWP的消息中可以包括第一部分和第二部分，用于配置第二BWP的消息中可以包括第一部分和第三部分。
所谓的侧行链路和蜂窝链路的公共配置信息，例如公共配置信息包括的信息既能用于第一BWP上的侧行链路，也能用于第二BWP上的蜂窝链路。例如第一部分可以包括如下信息中的至少一种：子载波间隔，CP类型，BWP的带宽，或BWP的标识。当然第一部分包括的信息不限于此。第二部分包括的用于第一BWP上的侧行链路上进行数据传输的配置信息，例如包括以下的至少一种：用于第一BWP上的侧行链路上的数据信道的配置信息，用于第一BWP上的侧行链路上的控制信道的配置信息，用于第一BWP上的侧行链 路上的参考信号(reference signal，RS)的配置信息，用于第一BWP上的侧行链路上的波束管理的配置信息，或用于第一BWP上的侧行链路上的功率控制信息的配置信息。当然用于第一BWP上的侧行链路上的进行数据传输的配置信息不限于此。第三部分包括的用于第二BWP上进行数据传输的配置信息，例如包括以下的至少一种：用于第二BWP上的蜂窝链路上的数据信道的配置信息，用于第二BWP上的蜂窝链路上的控制信道的配置信息，用于第二BWP上的蜂窝链路上的RS的配置信息，用于第二BWP上的蜂窝链路上的波束管理的配置信息，或用于第二BWP上的蜂窝链路上的功率控制信息的配置信息。当然用于第二BWP上的蜂窝链路上的进行数据传输的配置信息不限于此。
或者，如果认为第一BWP和第二BWP是具有对应关系的一对BWP，那么，如果第一BWP和第二BWP不是同一个BWP，例如网络设备通过一条消息为终端设备配置第一BWP，该消息例如称为第一消息，网络设备将第一消息发送给终端设备，则终端设备接收来自网络设备的第一消息。第一消息可以包括如下的至少一种：第一BWP的标识，第一BWP的子载波间隔，与第一BWP对应的第二BWP的标识，或第一BWP的带宽。例如第一消息可以包括与第一BWP对应的第二BWP的标识，也就是，第一消息虽然是配置第一BWP，但是第一消息中也可以包括对应的第二BWP的标识，从而通过第一消息就可以指示与第一BWP对应的第二BWP。或者，第一消息中也可以不包括与第一BWP对应的第二BWP的标识，则第一消息可以认为是专用于配置第一BWP，而第一BWP和第二BWP之间的对应关系，或者说与第一BWP对应的第二BWP的信息，可以通过其他方式指示，例如再通过另外的消息包括与第一BWP对应的第二BWP的标识。
S32、终端设备确定配置的第一BWP和第二BWP，第一BWP的中心频率与第二BWP的中心频率相同，第一BWP的带宽与第二BWP的带宽相同。其中，第一BWP的中心频率与第二BWP的中心频率相同，第一BWP的带宽与第二BWP的带宽相同，也可以理解为第一BWP和第二BWP的频域资源相同。
终端设备接收来自网络设备的第一BWP和第二BWP的配置信息后，就可以确定配置的第一BWP和第二BWP。
在本申请实施例中，第一BWP可以用于sidelink，第二BWP可以用于蜂窝链路，也就是，第一BWP是为sidelink配置的BWP，第二BWP是为蜂窝链路配置的BWP；或者第一BWP和第二BWP均用于蜂窝链路，也就是，第一BWP和第二BWP都是为蜂窝链路配置的BWP。例如蜂窝链路可以理解为Uu链路。例如，第一BWP和第二BWP均可以属于BWP集合，BWP集合可以是为蜂窝链路所配置的BWP集合。例如BWP集合中包括了一个载波上的4个BWP，也就是在该载波上为蜂窝链路配置了4个BWP集合，那么这4个BWP可以理解为4个第二BWP，例如可以为这4个第二BWP中的至少一个BWP再配置对应的第一BWP，例如可以为这4个第二BWP中的1个、2个、3个或4个BWP再分别配置对应的第一BWP，那么对于该载波而言，配置的第一BWP的数量可以是1、2、3或4。这些第一BWP和第二BWP都属于该BWP集合。
其中，为一个第二BWP所配置的对应的第一BWP，可以是同一个BWP，或者也可以是不同的BWP，也就是说，第一BWP和第二BWP可以是同一个BWP，或者也可以是不同的BWP。如果第一BWP和第二BWP是不同的BWP，也就是，第一BWP的中心频率和第二BWP的中心频率相同，第一BWP的带宽和第二BWP的带宽相同，但是第一BWP和第二BWP至少有一个参数的取值是不同的，例如第一BWP的子载波间隔(subcarrier  spacing，SCS)和第二BWP的子载波间隔不同。例如，第二BWP的带宽为20MHz，子载波间隔为15kHz，则配置的对应的用于sidelink的第二BWP的带宽也为20MHz，第二BWP的中心频率与第一BWP的中心频率也相同，第二BWP的子载波间隔例如为15kHz、30kHz或60kHz等。如果第二BWP的子载波间隔也为15kHz，则在第一BWP和第二BWP的除了带宽、中心频率和子载波间隔之外的其他参数的取值也都相同的情况下，第一BWP和第二BWP是同一个BWP，而如果第二BWP的子载波间隔不是15kHz，例如为30kHz或60kHz等，则第一BWP和第二BWP是不同的BWP。
本申请实施例中，第一BWP的带宽与第二BWP的带宽相同。其中，带宽可以是指：传输带宽、RF带宽、或信道带宽。相同包括：严格相等或近似相等。本申请实施例中的第一BWP与第二BWP的带宽相同，包括：第一BWP的传输带宽与第二BWP的传输带宽的大小相等或近似相等；第一BWP的RF带宽与第二BWP的RF带宽的大小相等或近似相等；第一BWP的信道带宽与第二BWP的信道带宽的大小相等或近似相等。
具体可选地，本申请实施例中的第一BWP与第二BWP的带宽相同，包括：第一BWP的传输带宽与第二BWP的传输带宽相同或近似相同；或者，第一BWP的RF带宽与第二BWP的RF带宽相同；或者第一BWP占用的信道带宽与第二BWP占用的信道带宽相同。传输带宽相同是指第一BWP和第二BWP上配置的最大可用于进行数据传输的资源块(resource block，RB)数相同。
具体可选地，当第一BWP的子载波间隔与第二BWP的子载波间隔不相同时，第一BWP的传输带宽和第二BWP的传输带宽相同，是指这两个BWP占用的RB所占用的频带带宽相同。例如：当第一BWP的SCS为15kHz，第二BWP的SCS为30kHz时，如果第一BWP可用于传输的RB数为22，第二BWP可用于传输的RB数为11，则可以认为这两者的传输带宽的大小完全相等，即15*22与30*11的大小完全相同。简而言之，如果第一BWP的传输带宽与第二BWP的传输带宽的比与它们的SCS的比值相反，即是指它们的传输带宽相同。上例中，它们的传输带宽的比值为2，它们的SCS的比值为1/2，所以它们的传输带宽相同。第一BWP与第二BWP的传输带宽近似相同是指不同的SCS配置时的可用的RB数与SCS的比值是一个近似的反比例关系。10MHz带宽为例，15kHz，30kHz和60kHz的SCS对应的可用RB数分别为52，24，11。它们的比值为近似的反比例关系。即15*52与30*24以及60*11近似相等。15kHz与30kHz的SCS之比为1/2，而它们可用的传输RB数的比为：52/24＝2.17。同样地，30kHz与60kHz的SCS之比为1/2，而它们可用的传输RB数的比为：24/11＝2.18。是一个近似成反比例的关系。
具体可选地，第一BWP的RF带宽与第二BWP的RF带宽相同是指，这两个BWP在频域上占用的带宽相同，或者说，发射机在频域上在发送这两个BWP时，它们占用的RF带宽相同。RF带宽包括两部分，即保护带和传输带宽。例如，对于一个RF带宽为10MHz的BWP而言，当一个BWP的子载波间隔更大时它需要有更大的保护带宽来达到带外指的要求，如对于15kHz的子载波间隔，需要312.5kHz的保护带，对于30kHz的子载波间隔，需要665kHz的带护带，对于60kHz的子载波间隔，需要1010kHz的带护带。在RF带宽一定的条件下，保护带越大，可用于数据传输的RB数占用的带宽就越小。在RF带宽相同时，因为保护带的问题，会导致在同样的RF带宽下，不同的子载波间隔配置时的可用的RB数与子载波间隔的比值不是严格的反比例关系。仍以10MHz带宽为例，15kHz，30kHz和60kHz的子载波间隔对应的可用RB数分别为52，24，11。它们的比值为近似的反比例 关系，即15*52与30*24以及60*11近似相等。
具体可选地，信道带宽是指支持一个小区的单个RF载波传输的RF带宽。当用于BWP时，是指这个BWP占用的带宽的上，也可以使用相同的带宽大小来作为一个载波进行传输。第一BWP占用的信道带宽与第二BWP占用的信道带宽相同是指，这两个BWP在频域上占用的带宽作为一个载波来传输时，它所占用的带宽相同。或者说，发射机在频域上在发送这两个BWP时，它们占用的RF带宽相同。RF带宽包括两部分，即保护带和传输带宽。例如，对于一个RF带宽为10MHz的BWP而言，当一个BWP的子载波间隔更大时它需要有更大的保护带宽来达到带外指的要求，如对于15kHz的子载波间隔，需要312.5kHz的保护带，对于30kHz的子载波间隔，需要665kHz的带护带，对于60kHz的子载波间隔，需要1010kHz的带护带。在RF带宽一定的条件下，保护带越大，可用于数据传输的RB数占用的带宽就越小。在RF带宽相同时，因为保护带的问题，会导致在同样的RF带宽下，不同的子载波间隔配置时的可用的RB数与子载波间隔的比值不是严格的反比例关系。仍以10MHz带宽为例，15kHz，30kHz和60kHz的子载波间隔对应的可用RB数分别为52，24，11。它们的比值为近似的反比例关系，即15*52与30*24以及60*11近似相等。
为了保证第一BWP的带宽和第二BWP的带宽相同，当第一BWP的子载波间隔是第二BWP的子载波间隔的M倍时，第二BWP的带宽占用的物理资源块(physical resource block，PRB)数可以与M整除。或者，如果考虑到第一BWP的带宽和第二BWP的带宽可能无法实现完全相同，而只能近似相同，那么当第一BWP的子载波间隔是第二BWP的子载波间隔的M倍时，第二BWP的带宽占用的PRB数也可能不能与M整除。例如，表1是一种可能的成对的BWP的带宽大小配置的取值，不同子载波间隔的BWP的带宽的大小只是近似整数倍。表1中，各种不同的SCS取值下占用的信道带宽或射频带宽相同。
表1
Figure PCTCN2019094925-appb-000001
表1中，N RB表示PRB的数量，第一行表示BWP的带宽。例如BWP的带宽为5MHz，如果子载波间隔为15kHz，例如为第二BWP，对应的PRB的数量为25个，如果子载波间隔为30kHz，例如为第一BWP，对应的PRB的数量为11个。可以看到，如果按照第一BWP和第二BWP的带宽完全相同的标准来看，那么，如果第一BWP的子载波间隔是第二BWP的子载波间隔的2倍，第二BWP的带宽占用的PRB数应该可以与2整除，也就是，例如BWP的带宽为5MHz，如果子载波间隔为15kHz，对应的PRB的数量为25个，如果子载波间隔为30kHz，则对应的PRB的数量应该为12个才对。由于保护带宽大小的差异，但是由于第一BWP的带宽和第二BWP的带宽可能无法实现完全相同，而只能认为 是近似相同，因此，如果第一BWP的子载波间隔是第二BWP的子载波间隔的M倍，则第二BWP的带宽占用的PRB数可以等于

或者等于

其中N为第一BWP占用的PRB的数量，

表示对X进行向上取整，
Figure PCTCN2019094925-appb-000005
表示对X进行向下取整。
或者，也可以较为严格地使得当第一BWP的子载波间隔是第二BWP的子载波间隔的M倍时，第二BWP的带宽占用的PRB数可以与M整除。例如，表2是一种可能的成对的BWP的带宽大小配置的取值，不同子载波间隔的BWP的带宽的大小是严格整数倍。
表2
Figure PCTCN2019094925-appb-000006
表2中，N RB表示PRB的数量，第一行表示BWP的带宽。例如BWP的带宽为5MHz，如果子载波间隔为15kHz，例如为第二BWP，对应的PRB的数量为20个，如果子载波间隔为30kHz，例如为第一BWP，对应的PRB的数量为10个。
具体的，当第一BWP的子载波间隔是第二BWP的子载波间隔的M倍时，第二BWP的带宽占用的PRB数是否可以与M整除，与第一BWP的带宽和第二BWP的带宽是严格相同还是近似相同有关，具体的不做限制。
其中，如果第一BWP和第二BWP是同一个BWP，例如第一BWP用于sidelink，第二BWP用于蜂窝链路，也就是同一个BWP既可以用于sidelink也可以用于蜂窝链路，为了尽量避免相互之间的干扰，可以使得sidelink在第一BWP上的传输资源与蜂窝链路在第二BWP上的传输资源时分复用(time division multiplexing，TDM)和/或频分复用(frequency division multiplexing，FDM)，也就是，使得sidelink在第一BWP上的传输资源与蜂窝链路在第二BWP上的传输资源TDM，或使得sidelink在第一BWP上的传输资源与蜂窝链路在第二BWP上的传输资源FDM，或使得sidelink在第一BWP上的传输资源与蜂窝链路在第二BWP上的传输资源TDM以及FDM。TDM的复用方式是指，在sidelink传输的时域资源(例如包括时隙(slot)或符号等)上，不会有蜂窝链路的传输。FDM的复用方式是指，在sidelink传输的时域资源上，同地可能有蜂窝链路的传输，但是在sidelink传输的频域资源(例如子载波、子载波或RB形成的资源集合等)上，不会有蜂窝链路的传输。
另外，按照目前的技术，对于一个终端设备来说，在一个载波上，一个时刻只能激活一个BWP。但是如果按照本申请实施例提供的方案为终端设备配置了第一BWP和对应的第二BWP，终端设备在第一BWP和第二BWP之间切换时可以无需重新配置RF参数，那么本申请实施例提出，对于一些能力比较强的终端设备来说，在一个载波上，一个时刻可以激活至少两个BWP，例如至少两个BWP可以包括第一BWP和对应的第二BWP。那么为了使得网络设备明确为终端设备激活多少个BWP，终端设备可以先向网络设备发送终端设备的能力信息，则网络设备接收来自终端设备的终端设备的能力信息，终端设备的能力 信息可以用于指示终端设备是否支持同时激活至少两个BWP，或者终端设备的能力信息可以用于指示终端设备支持激活的BWP的数量，或者终端设备的能力信息也可以用于指示终端设备的能力所属的类型。
例如不同类型的能力可以对应不同的激活的BWP的数量，而能力的类型和支持激活的BWP的数量之间的对应关系是终端设备和网络设备都明确的，因此终端设备只需通过能力信息指示终端设备的能力所属的类型，网络设备就可以确定终端设备支持激活的BWP的数量，或者能力的类型和是否支持激活至少两个BWP，这之间的对应关系是终端设备和网络设备都明确的，因此终端设备只需通过能力信息指示终端设备的能力所属的类型，网络设备就可以确定终端设备是否支持激活至少两个BWP。例如，如果终端设备具有第一类能力，则表明终端设备支持激活至少两个BWP，终端设备的能力信息可以指示终端设备的能力的类型为第一类，或终端设备的能力信息可以指示终端设备支持激活至少两个BWP，或终端设备的能力信息可以指示终端设备支持激活的BWP的数量大于或等于2，则网络设备可以为终端设备激活第一BWP和/或第二BWP，也就是网络设备可以为终端设备激活第一BWP或第二BWP，或为终端设备激活第一BWP和第二BWP，那么可以理解为第一BWP和第二BWP中至少有一个是激活的BWP，其中，如果第一BWP和第二BWP均为激活的BWP，也就是终端设备在一个时刻在一个载波上可以支持激活两个BWP。也可以反过来理解，如果第一BWP和第二BWP能够同时被激活，表明终端设备具有第一类能力。或者，如果终端设备具有第二类能力，表明终端设备不支持激活至少两个BWP，终端设备的能力信息可以指示终端设备的能力的类型为第二类，或终端设备的能力信息可以指示终端设备不支持激活至少两个BWP，或终端设备的能力信息可以指示终端设备支持激活的BWP的数量小于2，则网络设备可以为终端设备激活第一BWP或第二BWP，那么可以理解为第一BWP和第二BWP中只有一个是激活的BWP。也可以反过来理解，如果第一BWP和第二BWP在一个时刻只有其中一个能够被激活，表明终端设备具有第二类能力。
S33A、终端设备在第一BWP上传输数据，网络设备同样在第一BWP上传输数据。这里的数据可以终端设备发送、网络设备接收的上行数据，或者是终端设备接收、网络设备发送的下行数据。
其中，上述的S33A是图3A中的，以第一BWP是用于终端设备和网络设备之间通信的BWP为例的，如果第一BWP是用于终端设备和终端设备之间通信的BWP，那么S33A可以改为图3B中的S33B：终端设备在第一BWP上传输数据，另一终端设备同样在第一BWP上传输数据。这里的数据可以终端设备发送、另一终端设备接收的数据，或者是另一终端设备发送、该终端设备接收的数据。其中，如果将图3B所示的实施例应用在图2B所示的应用场景下，则终端设备可以是图2B中的终端设备1，另一终端设备可以是图2B中的终端设备2。其中，图3A和图3B中都包括S31和S32，只是S33A和S33B是不同的。当然，图3B中的S31中，网络设备需要向终端设备和另一终端设备均发送第一BWP和第二BWP的配置信息，终端设备要接收来自网络设备的第一BWP和第二BWP的配置信息，另一终端设备也要接收来自网络设备的第一BWP和第二BWP的配置信息。另外图3B的S32中，终端设备和另一终端设备都要确定配置的第一BWP和第二BWP，第一BWP的中心频率与第二BWP的中心频率相同，第一BWP的带宽与第二BWP的带宽相同。其中，第一BWP的中心频率与第二BWP的中心频率相同，第一BWP的带宽与第二BWP的带宽相同，也可以理解为第一BWP和第二BWP的频域资源相同。
在下文的描述过程中，均以S33A为例，也就是，以第一BWP是用于终端设备和网络设备之间通信的BWP为例。
例如第一BWP是激活的，则终端设备可以在第一BWP上发送数据。或者，如果第二BWP是激活的，则终端设备可以在第二BWP上发送数据。或者，如果第一BWP和第二BWP均是激活的，则终端设备可以在第一BWP上发送数据，或者在第二BWP上发送数据，或者在第一BWP和第二BWP上均发送数据。
作为一种可选的实施方式，为了支持系统的灵活性，可以在第一BWP上调度在第二BWP上的通信，和/或，可以在第二BWP上调度在第一BWP上的通信。具体的，可以在第一BWP上调度在第二BWP上的通信，或，在第二BWP上调度在第一BWP上的通信，或，在第一BWP上调度在第二BWP上的通信，以及在第二BWP上调度在第一BWP上的通信。
例如，第二BWP可以支持第一链路的传输，第一BWP可以支持第二链路和/或第三链路的传输。以第一BWP是用于sidelink的BWP、第二BWP是用于蜂窝链路的BWP为例，那么第一BWP可以支持sidelink和蜂窝链路的传输，例如第一链路为sidelink，第二链路为蜂窝链路，鉴于sidelink对于时延的要求可能是较高的，而用于蜂窝链路的第二BWP，可能很难满足时延的要求，因此第二BWP可能不支持sidelink，而只是支持蜂窝链路，例如第三链路为蜂窝链路。例如，终端设备在第一BWP的第二链路发送数据，则其他终端设备在第一BWP的第二链路接收来自该终端设备的数据，而如果终端设备在第一BWP的第三链路发送数据，则网络设备在第一BWP的第三链路接收来自该终端设备的数据。
例如，网络设备可以在第一BWP上发送第一调度信息，则终端设备在第一BWP上接收第一调度信息，第一调度信息可以用于调度第二BWP上的第一链路的数据传输。如果该终端设备在一个载波上在一个时刻只激活了一个BWP，那么终端设备接收第一调度信息时是激活了第一BWP，则终端设备在接收第一调度信息后，需要从第一BWP切换到第二BWP，也就是激活第二BWP，并去激活第一BWP，以根据第一调度信息的调度在第二BWP上传输信息，而BWP的切换几乎是零时延的；而如果该终端设备在一个载波上在一个时刻激活了至少两个BWP，例如激活了第一BWP和第二BWP，则终端设备在接收第一调度信息后无需切换BWP，只需根据第一调度信息的调度在第二BWP上传输数据即可，过程更为简单。可选的，第一调度信息还可以指示第二BWP，例如第一调度信息携带第二BWP的标识，则终端设备可以明确所调度的BWP是第二BWP。
再例如，网络设备还可以在第二BWP上发送第二调度信息，则终端设备在第二BWP上接收第二调度信息，第二调度信息可以用于调度第一BWP上的第二链路和/或第三链路的数据传输，也就是，第二调度信息可以用于调度第一BWP上的第二链路或第三链路的数据传输，或第二调度信息可以用于调度第一BWP上的第二链路和第三链路的数据传输。如果该终端设备在一个载波上在一个时刻只激活了一个BWP，那么终端设备接收第二调度信息时是激活了第二BWP，则终端设备在接收第二调度信息后，需要从第二BWP切换到第一BWP，也就是激活第一BWP，并去激活第二BWP，以根据第二调度信息的调度在第一BWP上传输信息，而BWP的切换几乎是零时延的；而如果该终端设备在一个载波上在一个时刻激活了至少两个BWP，例如激活了第一BWP和第二BWP，则终端设备在接收第二调度信息后无需切换BWP，只需根据第二调度信息的调度在第一BWP上传输数据即可，过程更为简单。可选的，第二调度信息还可以指示第一BWP，例如第二调度信息携带 第一BWP的标识，则终端设备可以明确所调度的BWP是第一BWP。
当然，在第一BWP上除了可以调度第二BWP的数据传输之外，也可以调度第一BWP上的第二链路和/或第三链路的数据传输。例如网络设备可以在第一BWP上发送第三调度信息，则终端设备在第一BWP上接收第三调度信息，第三调度信息可以用于调度第一BWP上的第一链路和/或第二链路的数据传输，也就是，第三调度信息可以用于调度第一BWP上的第二链路或第三链路的数据传输，或第三调度信息可以用于调度第一BWP上的第二链路和第三链路的数据传输。鉴于第一BWP上还可以调度其他的BWP(例如第二BWP)的数据传输，那么为了更好地区分在第一BWP上传输的调度信息究竟是调度哪个BWP的数据传输，网络设备可以在第一BWP上传输的调度信息中添加指示，来指示究竟调度的是哪个BWP的数据传输，例如网络设备可以通过第一调度信息指示第二BWP，那么同理，网络设备也可以通过第三调度信息指示第一BWP，例如第三调度信息中可以携带第一BWP的标识，从而终端设备就可以明确第三调度信息所调度的是第一BWP的数据传输。
同理，在第二BWP上除了可以调度第一BWP的数据传输之外，也可以调度第二BWP上的第三链路的数据传输。例如网络设备可以在第二BWP上发送第四调度信息，则终端设备在第二BWP上接收第四调度信息，第四调度信息可以用于调度第二BWP上的第三链路的数据传输。鉴于第二BWP上还可以调度其他的BWP(例如第一BWP)的数据传输，那么为了更好地区分在第一BWP上传输的调度信息究竟是调度哪个BWP的数据传输，网络设备可以在第二BWP上传输的调度信息中添加指示，来指示究竟调度的是哪个BWP的数据传输，例如网络设备可以通过第二调度信息指示第一BWP，那么同理，网络设备也可以通过第四调度信息指示第二BWP，例如第四调度信息中可以携带第二BWP的标识，从而终端设备就可以明确第四调度信息所调度的是第二BWP的数据传输。
作为一种可选的实施方式，在跨BWP进行调度时，是在当前的BWP的占用的PRB上进行指示，但被调度的BWP占用的PRB的数量与当前的BWP占用的PRB的数量可能是不同的，因此需要明确被调度的BWP所占用的PRB的数量。例如第二BWP的子载波间隔为15kHz，占用的PRB的数量为48，第一BWP的子载波间隔为30kHz，占用的PRB的数量为24。如果在第二BWP上指示第一BWP上的数据传输，是使用48个PRB来做频域资源的指示，但是第一BWP实际使用的PRB的数量为24，例如，可以令第二BWP占用的PRB的数量除以第一BWP的子载波间隔和第二BWP的子载波间隔相除后的值，对得到的数值向上取整或向下取整，得到第一BWP上的PRB的数量。也就是，第一BWP上的PRB的数量等于
Figure PCTCN2019094925-appb-000007
或者等于
Figure PCTCN2019094925-appb-000008
其中N为第二BWP占用的PRB的数量。而如果在第一BWP上指示第二BWP上的数据传输，是使用24个PRB来做频域资源的指示，但是第一BWP实际使用的PRB的数量为48，例如，可以令第二BWP占用的PRB的数量乘以第一BWP的子载波间隔和第二BWP的子载波间隔相除后的值，对得到的数值向上取整或向下取整，得到第一BWP上的PRB的数量。也就是，第二BWP上的PRB的数量等于
Figure PCTCN2019094925-appb-000009
或者等于
Figure PCTCN2019094925-appb-000010
其中K为第一BWP占用的PRB的数量。
例如，如果终端设备需要在第二BWP上的链路上传输数据，则终端设备可以从第一BWP切换到第二BWP。当然，如果第一BWP和第二BWP是同一个BWP，则终端设备可以无需切换，而可以直接在第二BWP的链路上传输数据，从而完全消除了切换时延；如果第一BWP和第二BWP是不同的BWP，则终端设备可以从第一BWP切换到第二BWP，从而在第二BWP的链路上传输数据。
在本申请实施例中，第一BWP和第二BWP从终端设备的RF模块来看，中心频率一样，带宽大小一样，因此即使重新配置第一BWP和/或第二BWP的除了中心频率和带宽之外的其它参数，终端设备在第一BWP和第二BWP之间进行切换时，也并不会因BWP的切换导致终端设备的RF模块的重调，从而产生中断。其中，重新配置第一BWP和/或第二BWP的参数，可以包括重新配置第一BWP的参数，或重新配置第二BWP的参数，或重新配置第一BWP的参数和第二BWP的参数。因此终端设备如果要从第一BWP切换到对应的第二BWP，或者从第二BWP切换到对应的第一BWP，基本可以实现零时延的切换，也就是终端设备基本可以在没有任何中断的条件下在2个BWP之间实现无缝的切换，从而达成了无中断高质量通信的目标，同时也获得了BWP的低成本、低功率消耗的优点。
图3A或图3B所示的实施例主要解决了减小在不同的BWP之间切换时带来的时延的问题，而终端设备在两个BWP之间进行切换时，可能还会对其他的BWP的工作产生影响。例如请参考图4A，为终端设备在一个载波上的用于蜂窝链路的BWP1和用于蜂窝链路的BWP2之间进行切换的示意，该切换会影响另一个载波上的用于sidelink的BWP3的工作，可能使得用于sidelink的BWP3的通信产生中断。或请参考图4B，也是终端设备在一个载波上的用于蜂窝链路的BWP1和用于蜂窝链路的BWP2之间进行切换的示意，该切换会影响同一个载波上的用于sidelink的BWP3的工作，可能使得用于sidelink的BWP3的通信产生中断。或请参考图4C，是终端设备在一个载波上的用于sidelink的BWP4和用于sidelink的BWP5之间进行切换的示意，该切换会影响另一个载波上的用于蜂窝链路的BWP6的工作，可能使得用于蜂窝链路的BWP6的通信产生中断。或请参考图4D，是终端设备在一个载波上的用于sidelink的BWP4和用于sidelink的BWP5之间进行切换的示意，该切换会影响同一个载波上的用于蜂窝链路的BWP6的工作，可能使得用于蜂窝链路的BWP6的通信产生中断。也就是说，当两个链路在相同或不同的载波上传输时，一个链路上的BWP发生切换时，会对另一个链路的传输产生影响，可能导致另一个链路中断，链路中断的根源在于：当进行BWP切换时，RF的频率需要调整，调整频率会对另一个载波或链路上的信号的频率产生波动；或者，当进行BWP切换时，会对终端设备的电源模块产生一定的冲击，该冲击也会影响到整个终端设备的稳定，从而使得另一个链路的通信产生中断。
为了解决该技术问题，本申请实施例还提供一种BWP切换方法，通过该方法能够尽量减小BWP的切换对其他BWP产生的影响。请参见图5，为该方法的流程图。在下文的介绍过程中，以该方法应用于图2A或图2B所示的网络架构为例。另外，该方法可由两个通信装置执行，这两个通信装置例如为第一通信装置和第二通信装置，其中，第一通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置，或者第一通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片系统。对于第二通信装置也是同样，第二通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置，或者第二通信装置可以是终 端设备或能够支持终端设备实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片系统。且对于第一通信装置和第二通信装置的实现方式均不做限制，例如第一通信装置可以是网络设备，第二通信装置是终端设备，或者第一通信装置和第二通信装置都是网络设备，或者第一通信装置和第二通信装置都是终端设备，或者第一通信装置是网络设备，第二通信装置是能够支持终端设备实现该方法所需的功能的通信装置，等等。其中，网络设备例如为基站。
为了便于介绍，在下文中，以该方法由网络设备和终端设备执行为例，也就是，以第一通信装置是网络设备、第二通信装置是终端设备为例。因为本实施例是以应用在图2A或图2B所示的网络架构为例，因此，如果将本实施例应用在图2A所示的网络架构，则下文中所述的网络设备可以是图2A所示的网络架构中的网络设备，下文中所述的终端设备可以是图2A所示的网络架构中的终端设备，或者，如果将本实施例应用在图2B所示的网络架构，则下文中所述的网络设备可以是图2B所示的网络架构中的网络设备，下文中所述的终端设备可以是图2B所示的网络架构中的第一终端设备或第二终端设备。
S51、网络设备在第一BWP上发送第一切换指示信息，终端设备在第一BWP上接收第一切换指示信息，第一切换指示信息用于指示切换到第三BWP。可以理解为，第一切换指示信息用于指示将第一BWP切换到第三BWP。其中，第一BWP和第三BWP可以属于一个载波，也可以属于不同的载波。
例如，第一BWP和第三BWP都是用于蜂窝链路的BWP，或者第一BWP和第三BWP都是用于sidelink的BWP。
S52、终端设备确定第一BWP的优先级和/或第二BWP的优先级。
也就是，终端设备确定第一BWP的优先级或第二BWP的优先级，或终端设备确定第一BWP的优先级和第二BWP的优先级。其中，第一BWP的优先级可以包括第一BWP本身的优先级或第一BWP上传输的业务(或描述为，传输的数据)的优先级中的至少一种，第二BWP的优先级可以包括第二BWP本身的优先级或第二BWP上传输的业务(或描述为，传输的数据)的优先级中的至少一种。
第一BWP和第二BWP可以属于一个载波，也可以属于不同的载波。第一BWP例如为用于蜂窝链路的BWP，第二BWP例如为用于sidelink的BWP，或者，第一BWP例如为用于sidelink的BWP，第二BWP例如为用于蜂窝链路的BWP。
S53、若第二BWP的优先级低于第一BWP的优先级，则终端设备将第一BWP切换到第三BWP，另外，若第二BWP的优先级低于第一BWP的优先级，则网络设备也确定终端设备将第一BWP切换到第三BWP。
终端设备在比较优先级时，可以将第二BWP的优先级和第一BWP的优先级直接进行比较，如果第二BWP的优先级低于第一BWP的优先级，表明第二BWP的重要性(或第二BWP上传输的业务的重要性)相较于第一BWP的重要性(或第一BWP上传输的业务的重要性)来说较低，则可以将第一BWP切换到第三BWP，切换过程虽然可能对第二BWP造成影响，但鉴于第二BWP或第二BWP上传输的业务不是特别重要，所以可以接受这种影响。
或者，终端设备在比较优先级时，也可以将第二BWP的优先级与门限值进行比较。例如，如果第二BWP的优先级低于第二门限，则从第一BWP切换到第三BWP。如果第二BWP的优先级低于第二门限，表明第二BWP的重要性(或第二BWP上传输的业务的 重要性)较低，则可以将第一BWP切换到第三BWP，切换过程虽然可能对第二BWP造成影响，但鉴于第二BWP或第二BWP上传输的业务不是特别重要，所以可以接受这种影响。
另外，如果第二BWP的优先级高于第一BWP的优先级，或者，如果第二BWP的优先级高于第一门限，则终端设备不将第一BWP切换到第三BWP，或者延迟将第一BWP切换到第三BWP，例如可以在第二BWP上的业务传输完毕后再将第一BWP切换到第三BWP，以在第二BWP或第二BWP上传输的业务较为重要时，可以尽量避免第二BWP上的通信的中断。
或者，如果第二BWP的优先级高于第一BWP的优先级，或者，如果第二BWP的优先级高于第一门限，终端设备可以继续将第一BWP切换到第三BWP，但在将第一BWP切换到第三BWP之后，终端设备可以重传在将第一BWP切换到第三BWP的过程中，在第二BWP上传输的至少一个数据包，其中，重传的在第二BWP上传输的至少一个数据包，就是受到第一BWP的切换影响的数据包。从而，通过重传的方式尽量减小切换所带来的第二BWP的通信中断的影响。
如果终端设备要将第一BWP切换到第三BWP，那么在切换之前，终端设备可以在第一BWP上发送第一信息，以供接收第一信息的设备确定第二BWP的中断时长，例如第一信息可以通过广播形式发送。另外，第一信息也可以认为是终端设备的发射机发送给终端设备的接收机的，以供终端设备的接收机确定第二BWP的中断时长。第一信息可以包括以下的至少一种信息：中断指示信息，中断的开始时间，中断时长指示信息，或中断时长的类型。其中，中断指示信息可以用于指示第二BWP的传输即将中断，或是指示要将第一BWP切换到第三BWP；中断的开始时间用于指示第二BWP的传输中断的开始时间，也可以理解为，是用于指示开始将第一BWP切换到第三BWP的时间；中断时长指示信息，可以用于指示第二BWP的传输中断的时长，或者理解为，是用于指示将第一BWP切换到第三BWP的切换过程的时长；根据中断时长的不同，可以将其分为不同的类型，那么中断时长的类型和中断时长之间可以认为具有对应关系，知道了中断时长的类型也就知道了中断时长，因此第一信息如果包括中断时长的类型，则接收第一信息的设备根据中断时长的类型就可以确定具体的中断时长。
如果第二BWP上的通信要中断，且如果第二BWP为用于蜂窝链路的BWP，则，如果在第二BWP上待传输的数据为下行数据，终端设备可以放弃在第二BWP上接收这部分下行数据，或者说终端设备可以丢弃这部分下行数据。如果终端设备放弃了在第二BWP上接收这部分下行数据，那么按照前文所介绍的技术方案，在终端设备将第一BWP切换到第三BWP之后，网络设备可以重传丢弃的这部分下行数据，终端设备可以重新接收这部分下行数据，以减小信息丢失的几率。或者，如果在第二BWP上待传输的数据为上行数据，终端设备丢弃在第二BWP上待传输的上行数据，或终端设备延迟发送在第二BWP上待传输的上行数据，例如终端设备可以在将第一BWP切换到第三BWP之后，再在第二BWP上发送这部分上行数据，以减小BWP的切换对数据传输带来的影响。如果终端设备丢弃了在第二BWP上待传输的上行数据，那么按照前文所介绍的技术方案，在终端设备将第一BWP切换到第三BWP之后，终端设备可以重传丢弃的这部分上行数据，以减小信息丢失的几率。
另外，例如终端设备还被配置了第四BWP，第二BWP和第四BWP可以属于一个载 波，也可以属于不同的载波。例如网络设备除了在第一BWP上向终端设备发送第一切换指示信息之外，还在第二BWP上向终端设备发送第二切换指示信息，第二切换指示信息用于指示将第二BWP切换到第四BWP。在这种情况下，第一BWP和第二BWP例如属于不同的载波。网络设备可以先发送第一切换指示信息再发送第二切换指示信息，或可以先发送第二切换指示信息再发送第一切换指示信息，或同时发送第二切换指示信息再发送第一切换指示信息。终端设备接收第一切换指示信息和第二切换指示信息后，就面临着两个切换过程。对此，终端设备包括但不限于如下几种不同的处理方式：
处理方式一，如果第二BWP的优先级低于第一BWP的优先级，或第二BWP的优先级低于第二门限，则表明第二BWP的重要性相较于第一BWP来说较低，或者表明第二BWP的重要性较低，则终端设备可以先将第一BWP切换到第三BWP，再将第二BWP切换到第四BWP，以优先完成优先级较高的BWP的切换。
处理方式二，如果终端设备的能力为第一能力，则终端设备只将第一BWP切换到第三BWP，而不将第二BWP切换到第四BWP，或者，终端设备只将第二BWP切换到第四BWP，而不将第一BWP切换到第三BWP。第一能力可以认为是较低的能力，如果终端设备的能力为第一能力，可以表明终端设备的能力不足以支撑两个切换过程，因此终端设备可以只进行一个切换过程。至于究竟是选择将第一BWP切换到第三BWP，还是选择将第二BWP切换到第四BWP，终端设备可以随机选择；或者可以按照切换指示信息的接收先后顺序来确定，例如先接收第一切换指示信息，则终端设备选择将第一BWP切换到第三BWP，或者先接收第二切换指示信息，则终端设备选择将第二BWP切换到第四BWP；或者也可以根据第一BWP的优先级和/或第二BWP的优先级来确定，例如第二BWP的优先级低于第一BWP的优先级，或第二BWP的优先级低于第二门限，则终端设备选择将第一BWP切换到第三BWP，否则，终端设备选择将第二BWP切换到第四BWP，等等。
处理方式三，如果终端设备的能力为第二能力，则终端设备同时将第一BWP切换到第三BWP，以及将第二BWP切换到第四BWP。第二能力可以认为是较高的能力，如果终端设备的能力为第二能力，可以表明终端设备的能力足以支持终端设备同时支持两个切换过程，因此终端设备可以同时将第一BWP切换到第三BWP，以及将第二BWP切换到第四BWP，这样可以加速切换过程，提高切换效率。
当然，在面临两个或更多的切换过程时，除了以上三种处理方式之外，终端设备还可能有其他的处理方式，本申请实施例并不限制。
如上的几种处理方式中，处理方式二和处理方式三都涉及到了终端设备的能力信息，因此，终端设备可以先向网络设备发送终端设备的能力信息，则网络设备接收来自终端设备的终端设备的能力信息，终端设备的能力信息可以用于指示终端设备是否支持同时将至少两个BWP分别切换到其他的BWP，和/或，终端设备在将一个BWP切换到另一个BWP时是否会影响终端设备的其他的BWP的工作。也就是，终端设备的能力信息可以用于指示终端设备是否支持同时将至少两个BWP分别切换到其他的BWP，或，指示终端设备在将一个BWP切换到另一个BWP时是否会影响终端设备的其他的BWP的工作，或，指示终端设备是否支持同时将至少两个BWP分别切换到其他的BWP，以及指示终端设备在将一个BWP切换到另一个BWP时是否会影响终端设备的其他的BWP的工作。其中，指示终端设备是否支持同时将至少两个BWP分别切换到其他的BWP，也就是指示终端设备是否支持至少两个切换过程。终端设备向网络设备发送了终端设备的能力信息，则网络设备 在指示终端设备进行BWP的切换时也就会根据终端设备的能力信息来指示，使得网络设备的指示更符合终端设备的实际能力。
