Description

一种配置方法及通信装置
本申请要求于2021年07月23日提交于中国专利局、申请号为202110839775.8、申请名称为“一种配置方法及通信装置”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
本申请涉及通信技术领域，尤其涉及一种配置方法及通信装置。
背景技术
为了保证终端设备和网络设备之间的数据传输，在终端设备进入无线资源控制(radio resource control，RRC)的连接态(RRC connected state)或者进入RRC非激活态(RRC inactive state)之后，网络设备会通过RRC专用信令为终端设备配置与该终端设备带宽能力匹配的至少一个信道带宽，该至少一个信道带宽中的每个信道带宽均不大于该终端设备的带宽能力，且每个信道带宽对应的子载波间隔(subcarrier spacing，SCS)不同。进一步地，针对该每个信道带宽而言，网络设备在该信道带宽内为终端设备配置至少一个带宽部分(bandwidth part，BWP)，该至少一个BWP用于与终端设备之间进行数据传输，并且该信道带宽上配置的每个BWP对应的SCS与该信道带宽的SCS相同，每个BWP的频域资源范围必须位于该信道带宽内。网络设备与终端设备之间的数据传输可以在前述至少一个BWP对应的频域资源范围内，进行动态的调整(例如本BWP调度、跨BWP调度的方法)，但在任何时刻终端设备仅能确定出一个BWP(即激活BWP)用于与网络设备进行数据传输，即可以理解为终端设备每次数据传输对应的频域资源只能在一个BWP对应的频域资源范围内。
通过这样配置BWP的方式，使得终端设备用于传输数据的BWP受限于终端设备的带宽能力，影响了终端设备的频选调度增益和频率分集增益；并且当终端设备需要在更大频域资源范围内的进行数据传输时，网络设备须得通过对终端设备的信道带宽进行重新配置方式来实现BWP的切换，满足终端设备的传输需求，通过这样配置BWP的方式导致配置时延大，从而影响终端设备的数据传输性能。

一、终端设备
本申请实施例中涉及的终端设备，是用户侧的一种用于接收或发射信号的实体。终端设备可以是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。终端设备也可以是连接到无线调制解调器的其他处理设备。终端设备可以与无线接入网(radio access network，RAN)进行通信。终端设备也可以称为无线终端设备、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment，UE)等等。终端设备可以是移动终端设备，如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，终端设备还可以是个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、等设备。常见的终端设备例如包括：汽车、无人机、机械臂、手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等，但本申请实施例不限于此。
需要知晓的是，本申请所涉及的终端设备可以是新无线(new radio，NR)能力缩减(reduced  capability，REDCAP)终端设备，也可以是未降低信道带宽的正常(NR legacy)终端设备。其中，NR REDCAP终端设备相对于NR legacy终端设备之间的区别包括以下至少一项：
1、带宽能力不同。例如NR Legacy终端设备最大可以支持在一个载波上同时使用100MHz频域资源和网络设备进行数据传输，而NR REDCAP终端设备最大可以支持在一个载波上同时使用20MHz或者10MHz或者5MHz频域资源和网络设备进行数据传输。
2、收发天线个数不同。例如NR Legacy终端设备最小支持的天线配置为4发2收，即在最小天线配置下，使用4根接收天线接收下行数据，使用2根发送天线发送上行数据；而NR REDCAP终端设备最大支持的天线配置低于4发2收，例如NR REDCAP UE只支持2收1发，或者也可以支持2收2发。
3、上行最大发射功率不同。例如NR Legacy终端设备的上行最大发射功率可以为23dBm或者26dBm，而NR REDCAP终端设备的上行最大发射功率只能为4dBm～20dBm中的一个值。
4、NR REDCAP终端设备与NR Legacy终端设备对应的协议版本不同，例如NR Rel-15、NR Rel-16终端设备可以认为是NR Legacy终端设备，NR REDCAP终端设备可以认为是NR Rel-17终端设备。
5、NR REDACP终端设备与NR Legacy终端设备支持的载波聚合(carrier aggregation，CA)能力不同，例如，NR Legacy终端设备可以支持载波聚合，而NR REDCAP终端设备不支持载波聚合；又例如，NR REDCAP与NR Legacy终端设备都支持载波聚合，但是NR Legacy终端设备同时支持的载波聚合的最大个数大于NR REDCAP终端设备同时支持的载波聚合的最大个数，例如NR Legacy终端设备可以最多同时支持5个载波或者32个载波的聚合，而NR REDCAP终端设备最多同时支持2个载波的聚合。
6、NR Legacy终端设备支持全双工FDD，而NR REDCAP终端设备仅支持半双工FDD。
7、NR REDCAP终端设备和NR Legacy终端设备对数据的处理时间能力不同，例如，NR Legacy终端设备接收下行数据与发送对该下行数据的反馈之间的最小时延小于NR REDCAP终端设备接收下行数据与发送对该下行数据的反馈之间的最小时延，和/或，NR Legacy终端设备发送上行数据与接收对该上行数据的反馈之间的最小时延小于NR REDCAP终端设备发送上行数据与接收对该上行数据的反馈之间的最小时延。
8、NR Legacy终端设备与NR REDCAP终端设备的处理能力不同。

为了方便理解本方案的内容，下面再对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1、带宽部分(bandwidth part，BWP)
由于NR中有多种带宽能力的终端，为了支持不同带宽能力的终端，NR中引入带宽部分(bandwidth part，BWP)。BWP是频域上一段连续的资源，包括上行BWP和下行BWP，分别用于上行传输和下行传输。通常在终端的初始接入阶段，基站给终端配置初始上行BWP和初始下行BWP，在终端进入RRC连接态之后，基站给终端额外配置一个或者多个终端专属的上行BWP和下行BWP。其中，上行信道或者上行信号传输完全在上行BWP内进行，下行信道或者信号传输完全在下行BWP内进行。终端可以收到多个BWP配置，但在同一时间，终端只能在工作在其中一个BWP上，此BWP称之为激活BWP。
在一个实施例中，BWP的带宽不能超过终端对应的最大带宽(即不能超出终端支持的带宽能力范围)，否则终端不能成功接入网络。
2、BWP切换时延
即指两个不同BWP之间进行切换的时延，例如，终端设备在接收到触发BWP切换的物理层信令之后，可以在BWP切换时延之后，将与基站之间的数据传输从BWP A切换到BWP B，其中，BWP A是包括触发BWP切换的物理层信令的BWP，BWP B为不同于BWP A的其他BWP。需要知晓的是，两个BWP不同，可认为两个BWP对应的配置参数有以下至少一项不同：
a)两个BWP对应的中心频点位置不同。
b)两个BWP对应的BWP带宽不同。
c)两个BWP对应的数据传输所使用的子载波间隔(subcarrier spacing，SCS)不同。
d)两个BWP对应的多输入多输出(multiple input multiple output，MIMO)数据传输层数或者天线数不同。
e)两个BWP对应的物理下行控制信道(physical downlink control channel，PDCCH)配置不同，或者对应的PDSCH配置不同，或者对应的物理上行控制信道(physical uplink control channel，PUCCH)配置不同，或者对应的物理上行共享信道(physical uplink shared channel，PUSCH)配置不同。
触发BWP切换的方式包括：基于物理层信令触发的BWP切换、基于RRC信令触发的BWP切换、基于定时器触发的BWP切换或基于RRC预配置或预定义触发的BWP切换。示意性地，下面针对基于物理层信令触发的BWP切换时延，基于RRC信令触发的BWP切换时延进行详细描述。
(一)基于物理层信令触发的BWP切换时延
基于物理层信令(例如下行控制信息(downlink control information，DCI))触发的BWP切换时延如图2所示，在下行BWP切换(即图2所示DL BWP切换)中，终端在下行时间单元n(即图2中所示的DL slot n)接收到网络设备发送的BWP切换请求信息，终端需要能在下行时间单元n之后的BWP切换时延(即图2中所示的T BWP切换时延)后最近的下行时间单元(即图2中所示的DL slot m)上接收PDSCH以及其他物理下行信道或下行信号；在上行BWP切换(即图2所示UL BWP切换)中，终端设备需要能在下行时间单元n之后的BWP切换时延(即图2中所示的T BWP切换时延)后最近的上行时间单元(即图2中所示的UL slot m)上发送PUSCH以及其他物理上行信道或上行信号。需要知晓的是，在图2中仅以时间单元为时隙(slot)进行示意性举例，并不能视为对本申请技术方案的限定。
通常，终端设备对应的BWP切换时延包括两种，如表1所示为终端设备支持的BWP切换时延。
表1
Figure PCTCN2022105195-appb-000001
其中，μ对应不同的SCS，具体地μ为0对应SCS为15KHz，μ为1对应SCS为30KHz，μ为2对应SCS为60KHz，μ为3对应SCS为120KHz。BWP切换时延的Type 1与Type 2根据终端设备上报的能力决定，例如，若终端设备上报能力为仅支持BWP切换时延Type 1，则终端设备基于物理层触发的BWP切换对应的时延如表1中Type1所示，如果终端设备上报能力仅支持Type 2，则终端设备基于物理层触发的BWP切换对应的时延如表中Type2所示。
(二)基于RRC信令触发的BWP切换时延
基于RRC信令触发的BWP切换时延，是指终端在下行时间单元n接收指示BWP切换的RRC信令，则终端需要在与该下行时间单元n间隔T RRC时延后最近的下行时间单元上接收PDSCH以及其他物理下行信道或下行信号，或者终端在与该下行时间单元n间隔T RRC时延后最近的上行时间单元上接收发送PUSCH以及其他物理上行信道或上行信号，其中T RRC时延是基于RRC信令触发的BWP切换时延，该T RRC时延的计算公式可参见公式(1)所示。
T RRC时延＝T RRCprocessingDelay+T BWPswitchDelayRRC    (1)
其中，T RRC时延是基于RRC信令触发的BWP切换时延，T RRCprocessingDelay为RRC过程引入的时延，T BWPswitchDelayRRC为UE执行BWP切换所需要的时间。
通常在终端设备进入RRC连接态或终端设备进入RRC非激活态之后，网络设备根据终端设备的带宽能力，为终端设备配置至少一个信道带宽(在本申请中，信道带宽也可称为载波)，该至少一个信道带宽中的每个信道带宽均不大于该终端设备的带宽能力。进一步地，网络设备在该至少一个信道带宽的频域范围内为终端设备配置至少一个BWP，该至少一个BWP用于终端设备与网络设备之间的数据传输。可见，通过这样的方式配置的BWP受限于终端设备的带宽能力，影响了终端设备的频选调度增益和频率分集增益。并且由于任何时刻终端设备仅能在一个激活BWP的频域资源范围内与网络设备进行数据传输，当终端设备需要在更大的频域资源范围内进行数据传输时，终端设备须得根据网络设备的指示进行BWP切换，导致产生BWP切换时延，而当BWP切换时延较大时，则会影响终端设备的数据传输性能。
本申请通过提供一种配置方法，可以配置多个SCS相同的信道带宽和多个SCS相同的BWP，当终端设备需要进行BWP切换的时候，不再需要通过RRC重新配置信道带宽，而是在预配置的多个SCS相同信道带宽范围内，实现多个SCS相同的BWP之间的快速地切换，故降低了终端设备在多个相关联BWP之间进行切换时的切换时延。进而在一些应用场景中，降低了BWP的切换时延，可以实现快速负荷均衡、高优先级业务避让以及快速干扰避让等，例如当某个BWP上负载较高时，可以通过本申请中的发明方案将一些业务数据传输切换到 负载较低的BWP上进行，从而实现快速负载均衡；又例如当前BWP上高优先级的业务需要传输时，可以通过本申请中的发明方案将一些业务数据传输切换到其他的BWP上进行，从而实现高优先级业务避让；又例如当某个BWP上干扰较高时，可以通过本申请中的发明方案将一些业务数据传输切换到干扰较小的BWP上进行，从而实现快速干扰避让。并且当BWP的频域资源范围超出该BWP对应信道带宽的频域资源范围之后，本申请可以根据BWP的频域资源范围重新确定一个包含该BWP的频域范围的信道带宽的方式，使该信道带宽的频域范围可以不受限于终端设备的带宽能力，进而使得BWP的频域范围也可以不再受限于终端设备的带宽能力，提升了终端设备数据传输中的频选调度增益和/或频率分集增益。
下面结合附图对本申请提供的配置方法及通信装置进行进一步介绍：
请参见图3，图3是本申请实施例提供的一种配置方法的流程示意图。如图3所示，该配置方法包括如下301～302，图3所示的方法执行主体可以为终端设备或终端设备中的芯片，也可以为网络设备或网络设备中的芯片。图3以终端设备和网络设备为执行主体为例进行说明。其中：
301、接收来自网络设备的第一配置信息，该第一配置信息用于配置多个第一信道带宽，该多个第一信道带宽中包括至少两个SCS相同的第二信道带宽。
网络设备可以通过RRC信令向终端设备发送第一配置信息，该第一配置信息用于配置多个第一信道带宽。终端设备根据该第一配置信息，从该网络设备的系统带宽中确定多个第一信道带宽，该多个第一信道带宽中包括至少两个SCS相同的第二信道带宽。
可以理解的是，该多个第一信道带宽中包括至少两个SCS相同的第二信道带宽，存在以下两种情形：

例如，该多个第一信道带宽包括：信道带宽10、信道带宽11和信道带宽12，该信道带宽10、信道带宽11和信道带宽12对应相同的SCS，该SCS为SCS1。

方式二、该第一配置信息包括第一子配置信息，该第一子配置信息包括至少两个SCS相同的第二信道带宽对应的至少两个频域位置、至少两个频域起始位置或至少两个频域偏移值 中的一项或多项。
在这种配置方式中，通过该第一子配置信息配置该至少两个SCS相同的第二信道带宽时，一种可选的实施方式是：在某一个第二信道带宽的配置信息中添加至少两个offsetToCarrier字段，该多个offsetToCarrier字段用于指示该至少两个第二信道带宽的频域位置(或称为频域起始位置或频域偏移值)。
示例性地，该第一子配置信息包括：subcarrierSpacing字段指示第二信道带宽的SCS为SCS1，carrierBandwidth指示第二信道带宽的带宽大小为40MHz，offsetToCarrier字段1指示第二信道带宽的频域位置为Location1，offsetToCarrier字段2指示第二信道带宽的频域位置为Location2，offsetToCarrier字段3指示第二信道带宽的频域位置为Location3。则通过该第一子配置信息配置的3个第二信道带宽：信道带宽1、信道带宽2和信道带宽3。其中，信道带宽1：SCS为SCS1，带宽大小为40MHz，在系统带宽中的位置为Location1；信道带宽2：SCS为SCS1，带宽大小为40MHz，在系统带宽中的位置为Location2；信道带宽3：SCS为SCS1，带宽大小为40MHz，在系统带宽中的位置为Location3。可以理解为在如图4所示的一个第一信道带宽的配置信息中添加了至少两个offsetToCarrier字段，该至少两个offsetToCarrier字段用于指示该至少两个第二信道带宽的频域位置(或称为频域起始位置或频域偏移值)。

可见，方式二中第一子配置信息配置的多个第二信道带宽中，各个第二信道带宽的配置信息中仅有频域位置不同。方式二的配置方式相较于方式一的配置方式而言，网络设备可以通过较少的通信传输资源配置至少两个SCS相同的第二信道带宽。需要理解的是，该多个SCS相同的第二信道带宽可以认为是多个不同的信道带宽，也可以理解为同一信道带宽具有不同频域位置。在这种情况下，该多个SCS相同的信道带宽可构成一个信道带宽集合或者信道带宽组(channel bandwidth group)。
情形二：该多个第一信道带宽包括一组或多组SCS相同的第二信道带宽和其他第一信道带宽(可以理解为SCS和该组第二信道带宽的SCS不同的第一信道带宽)。
在一个示例中，该多个第一信道带宽中包括一组SCS相同的第二信道带宽，例如该多个第一信道带宽包括：信道带宽10、信道带宽11和信道带宽12和信道带宽13。其中，信道带宽10和信道带宽12对应相同的SCS为SCS1，信道带宽11对应SCS2、信道带宽13对应SCS3。
在另一个示例中，该多个第一信道带宽包括多组SCS相同的第二信道带宽，例如该多个第一信道带宽包括2组SCS相同的第二信道带宽：信道带宽10、信道带宽11、信道带宽12、 信道带宽13和信道带宽14。其中，信道带宽10、信道带宽11和信道带宽12对应相同的SCS，该SCS为SCS1；信道带宽13和信道带宽14对应相同的SCS，该SCS为SCS2。
在此种情形下，第一配置信息包括第一子配置信息和第二子配置信息，该第一子配置信息用于配置至少两个SCS相同的第二信道带宽，该第二子配置信息用于配置除该第二信道带宽之外的第三信道带宽(即前述其他第一信道带宽)。可以理解为通过第一子配置信息配置的第一信道带宽的SCS相同，通过第二子配置信息配置的第一信道带宽的SCS不同。
具体地，在这种情形下，该第一配置信息配置多个第一信道带宽的配置方式包括：
方式一、该第一配置信息包括多个第二信道带宽的配置信息，每个第二信道带宽的配置信息中有且仅包含一个频域位置(或称为频域起始位置或频域偏移值)。该第二子配置信息多个第三信道带宽的配置信息，每个第三信道带宽的配置信息中有且仅包含一个频域位置(或称为频域起始位置或频域偏移值)。
即可以理解为，在这种配置方式中，该第一配置信息包括至少两个频域位置，每个频域位置用于指示第一信道带宽的位置。
方式二、该第一子配置信息包括至少两个SCS相同的第二信道带宽对应的至少两个频域位置、至少两个频域起始位置或至少两个频域偏移值中的一项或多项。该第二子配置信息多个第三信道带宽的配置信息，每个第三信道带宽的配置信息中有且仅包含一个频域位置(或称为频域起始位置或频域偏移值)。
即可以理解为，在这种配置方式中，该第一配置信息包括第一子配置信息和第二配置信息。其中，第一子配置信息包括一组或多组第二信道带宽的配置信息，每组第二信道带宽信息中包括一个subcarrierSpacing字段、一个carrierBandwidth字段和多个offsetToCarrier字段(或一个offsetToCarrier字段中存在多个频域位置)。第二子配置信息包括多个第三信道带宽的配置信息，即多个subcarrierSpacing字段、多个carrierBandwidth字段和多个offsetToCarrier字段。
需要声明的是，在本申请中该多个SCS相同的第二信道带宽对应的频域资源之间可以有重叠也可以没有重叠，本申请对此不作具体限定。本申请的信道带宽配置既可以针对下行信道带宽和上行信道带宽分别配置，也可以仅对下行信道带宽配置，也可以仅对上行信道带宽配置，还可以针对下行信道带宽和上行信道带宽联合配置，本申请对此亦不作具体限定。
302、接收来自网络设备的第二配置信息，该第二配置信息用于配置多个第一BWP，该多个第一BWP包括至少两个SCS相同的第二BWP，该多个第二BWP的SCS与前述第二信道带宽对应的SCS相同。
网络设备向终端设备发送第二配置信息，该第二配置信息用于在多个第一信道带宽中配置多个第一BWP。其中，第二配置信息中包括一套BWP配置参数或多套BWP配置参数。需要了解的是，该BWP配置参数包括但不限于以下参数中的一种或多种：BWP的索引(或称为BWP标识或BWP ID)、BWP的频域位置、BWP的带宽大小、BWP的SCS、BWP的循环前缀(cyclic prefix)、其他公共参数(例如小区专属参数)、专用参数(用户专用参数)、BWP上的物理传输信道配置或BWP上物理信道配置。终端设备根据该一套或多套BWP配置参数，在各套BWP配置参数相对应的第一信道带宽中配置第一BWP。
需要说明的是，在本申请中BWP配置参数对应的信道带宽(或称为BWP对应的信道带宽，或是BWP相关联的信道带宽)，均可理解为该BWP的SCS与该信道带宽的SCS相同。本申请对每个第一信道带宽内配置的BWP的个数不限定，即可以在一个第一信道带宽中配置多个BWP，也可以在一个第一信道带宽中配置1个BWP。
下面针对第二配置信息包括一套BWP配置参数，或第二配置信息包括多套BWP配置参数的情况进行详细描述。
方式一、该第二配置信息包括多套BWP配置参数。
其中，该多套BWP配置参数中每套BWP配置参数的SCS可以相同，也可以不同。即在该多个第一信道带宽中各个第一信道带宽的SCS不同的情况下；或，该多个第一信道带宽中部分第一信道带宽的SCS相同，部分第一信道带宽的SCS不同的情况下；或，该多个第一信道带宽中全部第一信道带宽的SCS相同的情况下，均可适用此方式配置第一BWP。
示例性地，多个第一信道带宽包括：信道带宽10、信道带宽11和信道带宽12和信道带宽13。其中，信道带宽10和信道带宽12对应相同的SCS为SCS1，信道带宽11对应SCS2、信道带宽13对应SCS3。第二配置信息包括多套BWP配置参数，其中：BWP#0配置参数中SCS为SCS1，BWP#1的配置参数中SCS为SCS2，BWP#2的配置参数中SCS为SCS3。在这种情况下，终端设备接收该第二配置信息之后，由于BWP#0的SCS与信道带宽10和信道带宽12的SCS相同，则根据BWP#0配置参数在信道带宽10中配置第一BWP，根据BWP#0配置参数在信道带宽12中配置第一BWP；BWP#1的SCS与信道带宽11的SCS相同，则根据BWP#1配置参数在信道带宽11中配置第一BWP；BWP#2的SCS与信道带宽13的SCS相同，则根据BWP#2配置参数在信道带宽13中配置第一BWP。
通过这样的配置BWP的方式，由于多个第一信道带宽中包括至少两个SCS相同的第二信道带宽，则在相同SCS的第二信道带宽中配置的第一BWP之间相关联，即为前述第二BWP。
方式二、该第二配置信息包括一套BWP配置参数。
该第二配置信息包括一套BWP配置参数，则终端设备根据该BWP配置参数中的SCS，从多个第一信道带宽中确定出与该BWP配置参数中SCS相同的第一信道带宽。进一步地，根据该BWP配置参数在与该BWP配置参数中SCS相同的第一信道带宽中配置多个第一BWP。
示例性地，多个第一信道带宽包括：信道带宽10、信道带宽11和信道带宽12和信道带宽13。其中，信道带宽10和信道带宽12对应相同的SCS为SCS1，信道带宽11对应SCS2、信道带宽13对应SCS3。第二配置信息中包括一套BWP配置参数，该BWP配置参数的SCS为SCS1，则终端设备可以根据该第二配置信息在信道带宽10和信道带宽11中确定BWP。
在一个应用场景中，当该多个第一信道带宽中各个第一信道带宽的SCS相同时，可以通过一套BWP配置参数在该多个第一信道带宽中确定SCS相同的至少两个第二信道带宽。
可见，通过此种方式配置至少两个SCS相同的第二BWP，适用于该多个第一信道带宽中存在与该BWP配置参数中SCS相同的至少两个第二信道带宽。
需要知晓的是，前述步骤301和302的执行顺序仅作为示意性的一个讲解，并不能视为对本申请的一个具体限定。即是说，301和302的执行顺序可以是先执行301，后执行302；也可以是先执行302后执行301；还可以是301和302同时执行。
请参见图5，图5是本申请实施例提供的另一种配置方法的流程示意图。如图5所示，该配置方法包括如下501～502，图5所示的方法执行主体可以为终端设备或终端设备中的芯片，也可以为网络设备或网络设备中的芯片。图5以终端设备和网络设备为执行主体为例进行说明。其中：
501、终端设备接收来自网络设备的第三配置信息，该第三配置信息用于配置多个第一信 道带宽，该多个第一信道带宽中每个第一信道带宽的SCS不同。
网络设备可以通过RRC信令向终端设备发送第三配置信息，该第三配置信息用于配置多个第一信道带宽，该多个第一信道带宽中每个第一信道带宽的SCS不同，可以理解为第一信道带宽与SCS之间是一一对应的关系。
示例性地，网络设备通过RRC信令向终端设备发送第三配置信息，该第三配置信息包括多个如图4所示的第一信道带宽的配置信息，该第一信道带宽的配置信息包括：用于指示该第一信道带宽的SCS的subcarrierSpacing字段，用于指示该第一信道带宽的带宽大小的carrierBandwidth字段，用于指示该第一信道带宽的频域位置(或称为频域起始位置或频域偏移值)的offsetToCarrier字段。进一步地，终端设备根据多个如图4所示的第一信道带宽的配置信息确定多个第一信道带宽。例如，该多个第一信道带宽的配置信息包括：subcarrierSpacing字段指示SCS1、carrierBandwidth字段指示30MHz、offsetToCarrier字段指示Location1；subcarrierSpacing字段指示SCS2、carrierBandwidth字段指示50MHz、offsetToCarrier字段指示Location2；subcarrierSpacing字段指示SCS3、carrierBandwidth字段指示60MHz、offsetToCarrier字段指示Location3。进一步地，终端设备根据该多个第一信道带宽的配置信息，确定信道带宽1的SCS为SCS1、带宽大小为30MHz，频域位置为Location1；信道带宽2的SCS为SCS2、带宽大小为50MHz，频域位置为Location2；信道带宽3的SCS为SCS3、带宽大小为60MHz，频域位置为Location3。
502、终端设备接收来自网络设备的第四配置信息，该第四配置信息用于配置多个第一BWP，该多个第一BWP与该多个第一信道带宽相关联，该多个第一BWP包括至少两个SCS相同的第二BWP。
网络设备向终端设备发送第四配置信息，该第四配置信息用于在前述多个第一信道带宽中配置多个第一BWP。其中，该第四配置信息中包括一套BWP配置参数或多套BWP配置参数。该配置参数包括但不限于以下参数中的一种或多种：BWP的索引(或称为BWP标识或BWP ID)、BWP的频域位置、BWP的带宽大小、BWP的SCS、BWP的循环前缀(cyclic prefix)、其他公共参数(例如小区专属参数)、专用参数(用户专用参数)、BWP上的物理传输信道配置或BWP上物理信道配置。终端设备根据该一套或多套BWP配置参数，在各套BWP配置参数相对应的第一信道带宽中配置第一BWP。需要知晓的是，BWP配置参数中SCS与信道带宽中SCS相同的情况下，可根据该BWP配置参数在该信道带宽中配置一个或多个BWP。
示例性地，该多个第一信道带宽包括：信道带宽20、信道带宽21和信道带宽22，其中，信道带宽20对应SCS1、信道带宽21对应SCS2、信道带宽22对应SCS3，SCS1不同于SCS2不同于SCS3。第四配置信息中包括多套第一BWP配置参数，其中BWP#0配置参数中SCS为SCS1，BWP#1的配置参数中SCS为SCS2，BWP#2的配置参数中SCS为SCS3。进一步地，终端设备在信道带宽20中确定一个或多个BWP#0，在信道带宽21中确定一个或多个BWP#1，在信道带宽22中确定一个或多个BWP#2。
在一个应用场景中，由于该第一信道带宽中可配置多个BWP，同一个信道带宽配置的BWP的SCS相同，即为前述第二BWP。由于第一信道带宽是网络设备根据终端设备的带宽能力配置的，故该第一信道带宽受限于终端设备的带宽能力。在该第二BWP的频域资源范围超出该第二BWP对应的第一信道带宽的频域的情况下，为了避免第二BWP受限于终端设备的带宽能力。终端设备(或网络设备)确定第四信道带宽，该第四信道带宽的频域范围包括该第二BWP的频域资源范围。
需要知晓的是，本申请仅以第二BWP的频域资源范围超出该第二BWP对应的第一信道带宽的频域资源范围，对根据BWP确定信道带宽的方法进行示意性的讲解，并不应视为对本申请的一个具体限定。即可以理解为，当前述第一BWP的频域范围超出该第一BWP对应的第一信道带宽的频域资源范围，依旧可通过该根据BWP确定信道带宽的方法，确定出包括该第一BWP的频域范围的信道带宽。
例如，信道带宽20的SCS与BWP#0配置参数中SCS相同，则该信道带宽20为BWP#0对应的第一信道带宽，根据该BWP#0配置参数在信道带宽20中配置至少一个BWP#0。该至少一个BWP#0包括：BWP#0 1和BWP#0 2，当BWP#0 2的频域资源范围超出该信道带宽20的频域资源范围时，终端设备(或网络设备)确定第四信道带宽，该第四信道带宽包括该BWP#0 2的频域资源。
在一个可选的实施方式中，该第四信道带宽满足以下条件中的一项或多项：
a)该第四信道带宽的频域资源的起始位置与该第二BWP的频域资源起始位置相同。可以理解为，根据该第二BWP的频域资源起始位置确定第四信道带宽，该第四信道带宽的大小至少包括该第二BWP的频域资源。
b)第四信道带宽的SCS与第二BWP的SCS相同。可以理解为，根据第二BWP的SCS确定第四信道带宽的SCS，该第四信道带宽的大小至少包括该第二BWP的频域资源。
c)第四信道带宽的大小与第二BWP对应的第一信道带宽的大小相同。例如，根据该BWP#0配置参数在信道带宽20中配置BWP#0 2，当BWP#0 2的频域资源范围超出该信道带宽20的频域资源范围时，确定第四信道带宽，该第四信道带宽的带宽大小和信道带宽20的带宽大小相同。
d)第二BWP与第四信道带宽的相对位置与第四BWP与第二BWP对应的第一信道带宽的相对位置相同，其中第二BWP与该第四BWP的SCS相同。例如，信道带宽20的SCS与BWP#0配置参数中SCS相同，则该信道带宽20为BWP#0对应的第一信道带宽，根据该BWP#0配置参数在信道带宽20中配置至少一个BWP#0。该至少一个BWP#0包括：BWP#0 1和BWP#0 2，当BWP#0 2的频域资源范围超出该信道带宽20的频域资源范围时，终端设备(或网络设备)确定第四信道带宽，该BWP#0 2与第四信道带宽的相对位置，与BWP#0 1和信道带宽20的相对位置相同。
可见，通过此种方式配置至少两个SCS相同的第二BWP，可以在确定多个相关联的BWP的同时，通过根据BWP确定信道带宽的方式，避免BWP受限于该BWP对应信道带宽的频域范围，从而避免终端设备的BWP受限于终端设备的带宽能力，以提升终端设备的频选调度增益和/或频率分集增益。
需要知晓的时，前述步骤501和502的执行顺序仅作为示意性的讲解，并不能视为对本申请的一个具体限定。即是说，501和502的执行顺序可以是先执行501，后执行502；也可以是先执行502后执行501；还可以是501和502同时执行。
基于图3或图5所提供的配置方法，在一个可选的实施方式中，终端设备还可以接收来自网络设备的控制信息，该控制信息用于指示第一时刻激活的第五BWP。进一步地，在该第五BWP和第六BWP相关联的情况下，终端设备从第六BWP切换至第五BWP的切换时延为第一切换时延，第六BWP为第二时刻激活的BWP，该第二时刻在第一时刻之前。在第五BWP和第六BWP不相关联的情况下，终端设备从第六BWP切换至第五BWP的切换时延为第二切换时延。其中，第一切换时延小于第二切换时延，第五BWP与第六BWP不同。
例如，在当前时刻(即前述第二时刻)终端设备用于传输数据的激活BWP为BWP1(即前述第六BWP)。终端设备接收来自网络设备的控制信息，该控制信息指示了第二时刻之后的第一时刻激活的第五BWP，该控制信息中携带有第五BWP的BWP标识(或子标识)。进一步地，在该第五BWP和第六BWP相关联的情况下，终端设备从第六BWP切换至第五BWP的切换时延为第一切换时延；在该第五BWP和第六BWP不相关联的情况下，终端设备从第六BWP切换至第五BWP的切换时延为第二切换时延。其中，第一切换时延小于第二切换时延。即可以理解为，终端设备在两个相关联的BWP之间切换的切换时延，小于终端设备在两个不相关联的BWP之间切换的切换时延。
针对两个BWP相关联需要说明的是，在第五BWP和第六BWP相关联的情况下，该第五BWP和第六BWP满足以下条件中的一种或多种：
a)第五BWP的带宽大小和该第六BWP的带宽大小相同。例如，第五BWP的带宽大小为20MHz，第六BWP的带宽大小也为20MHz，则视为第五BWP和第六BWP相关联。
b)第五BWP的SCS和第六BWP的SCS相同。例如，第五BWP的SCS与第六BWP的SCS均为SCS1，则视为第五BWP和第六BWP相关联。
c)第五BWP的物理传输信道配置和第六BWP的物理传输信道配置相同。需要知晓的是，该物理传输信道配置包括但不限于PDCCH的配置、PDSCH的配置、PUCCH的配置或PUSCH的配置。例如，第五BWP中PDCCH的传输配置(传输配置包括但不限于传输速度)与第六BWP中PDCCH的传输配置相同，则视为第五BWP和第六BWP相关联。
d)第五BWP的物理信号配置和第六BWP的物理信号配置相同。需要知晓的是，该物理信号配置包括但不限于调参考信号(demodulation reference signal，DMRS)的配置、信道状态信息参考信号(channel state information reference signal，CSI-RS)的配置、跟踪参考信号(tracking reference signal，TRS)的配置、探测参考信号(sounding reference signal，SRS)的配置等。例如，第五BWP中DMRS的配置和第六BWP中DMRS的配置相同，则视为第五BWP和第六BWP相关联。
e)第五BWP在该第五BWP对应的第一信道带宽内的相对位置与第六BWP在该第六BWP对应的第一信道带宽内的相对位置相同。BWP和信道带宽的相对位置是指BWP的频域资源中心位置与该信道带宽的频域资源中心位置之间的相对位置，或者，BWP的频域资源起始位置与该信道带宽的频域资源起始位置之间的相对位置，或者，指BWP的频域资源偏移值(offset)。例如，请参见图6a所示，以第五BWP的频域资源处于该第五BWP对应的第一信道带宽的频域资源的中间位置(即第五BWP的频域资源中心位置与该第一信道带宽的频域资源中心位置重合)，第六BWP的频域资源也在该第六BWP对应的第一信道带宽的频域资源的中间位置(即第六BWP的频域资源中心位置与该第一信道带宽的频域资源中心位置重合)，则视为第五BWP和第六BWP相关联。
f)第五BWP的标识与第六BWP的标识相同，其中，第五BWP对应该标识下的子标识与第六BWP对应该标识下的子标识不同。例如，请参见图6b所示，仅有频域资源位置不同的多个BWP对应同一BWP标识，每个BWP在该BWP标识下具有子标识。在这种情况下，第五BWP的BWP标识和第六BWP的BWP标识均为BWP#0，该第五BWP的子标识为Location#0，该第六BWP的子标识为Location#1。在这种情况下，可以视为第五BWP和第六BWP不同，且第五BWP和第六BWP相关联。
针对两个相关联BWP之间的切换时延和两个不相关联BWP之间的切换时延，需要说明的是，由于基于触发BWP切换的方式不同，BWP切换时延的具体确定方式不同。示意性地， 下面针对BWP切换时延分为：基于物理层信令触发的BWP切换时延，基于RRC信令触发的BWP切换时延的情况，对第一切换时延和第二切换时延进行展开描述。
(一)基于物理层信令触发的BWP切换时延
针对基于物理层信令触发的BWP切换时延的情况，两个不相关联BWP之间的切换时延(即前述第二切换时延)可参见前述表1所示，两个相关联BWP之间的切换时延(即前述第一切换时延)可参见表2所示。
表2
Figure PCTCN2022105195-appb-000002
其中，μ对应不同的SCS，具体地μ为0对应SCS为15KHz，μ为1对应SCS为30KHz，μ为2对应SCS为60KHz，μ为3对应SCS为120KHz。BWP切换时延的Type 1与Type 2根据终端设备上报的能力决定。例如，若终端设备上报能力仅支持BWP切换时延Type 1，则基于物理层触发的BWP切换对应的时延如表1中Type1所示，如果终端设备上报能力仅支持Type 2，则基于物理层触发的BWP切换对应的时延如表中Type2所示。
在这种情况下，当终端设备上报能力为该终端设备仅支持Type1时，当μ为1时，根据表1可确定终端设备在两个不相关联BWP之间进行切换时的切换时延(即前述第二切换时延)为2个slot，而根据表2可确定终端设备在两个相关联BWP之间进行切换时的切换时延为(即前述第一切换时延)为小于2个slot。当终端设备上报能力为该终端设备仅支持Type2时，当μ为1时，根据表1可确定终端设备在两个不相关联BWP之间进行切换时的切换时延(即前述第二切换时延)为5个slot，而根据表2可确定终端设备在两个相关联BWP之间进行切换时的切换时延为(即前述第一切换时延)为小于5个slot。
(二)基于RRC信令触发的BWP切换时延
根据前述公式(1)可知，在这种情况下BWP切换时延由两部分组成：T RRCprocessingDelay为RRC过程引入的时延，T BWPswitchDelayRRC为UE执行BWP切换所需要的时间。终端设备在两个相关联BWP之间切换的第一切换时延小于终端设备在两个不相关联的BWP之间切换的第二切换时延，具体表现在：终端设备在两个相关联BWP之间切换的T RRCprocessingDelay小于在两个不相关联BWP之间切换的T RRCprocessingDelay；或者，终端设备在两个相关联BWP之间切换的T BWPswitchDelayRRC小于在两个不相关联BWP之间切换的T BWPswitchDelayRRC。
需要知晓的是，在该第五BWP和第六BWP相关联的情况下，该至少两个SCS相同的第二BWP包括该第五BWP和第六BWP。即可以理解为，该至少两个SCS相同的第二BWP之间互相关联。
在一种可能的实现中，该多个第一信道带宽中包括默认(default)信道带宽。在一个应用场景中，该默认信道带宽用于在终端设备收到多个信道带宽配置信息时，将该默认(default)信道带宽确定为初始工作的信道带宽和/或相应的BWP。在又一种应用场景，当终端设备在当前工作的BWP上长时间没有进行数据传输时，终端设备可以切换回默认的信道带宽和/或 相应的默认的BWP。
其中，该default信道带宽可以是根据通信协议预先设定的，也可以是根据网络设备的指示(例如通过信令指示等)确定的。在一种可选的实施方式中，终端设备接收来自网络设备的指示信息和第二配置信息，根据该指示信息在该至少两个SCS相同的第二信道带宽中确定default信道带宽，并根据该第二配置信息中包括的BWP配置参数在该default信道带宽中确定有效状态的BWP。在另一种可选的实施方式中，终端设备(或网络设备)通过图5所示的方式确定第四信道带宽之后，在与该第四信道带宽的SCS相同的第一信道带宽和该第四信道带宽中确定default信道带宽。
示例性地，在一个应用场景中，多个第一信道带宽包括：信道带宽10、信道带宽11和信道带宽12和信道带宽13。其中，信道带宽10和信道带宽12对应相同的SCS为SCS1，信道带宽11对应SCS2、信道带宽13对应SCS3。第二配置信息包括多套BWP配置参数，其中：BWP#0配置参数中SCS为SCS1，BWP#1的配置参数中SCS为SCS2，BWP#2的配置参数中SCS为SCS3。可见，在此应用场景中第二信道带宽包括：信道带宽10和信道带宽12。根据网络设备的指示确定default信道带宽为信道带宽10。在这种情况下，尽管BWP#0配置参数的SCS与信道带宽12的SCS相同，终端设备也不会根据BWP#0配置参数在信道带宽12中确定BWP#0。终端设备根据第二配置信息中BWP#0配置参数(该配置参数中SCS为SCS1)在仅在信道带宽10(default信道带宽)中确定BWP#0。
通过这样的方式，可以在该应用场景中减少多个信道带宽同时工作而造成的资源浪费的情况，同时也提升了确定BWP的灵活性。
在一个可选的实现中，终端设备接收来自网络设备的指示信息，该指示信息用于指示该至少两个SCS相同的第二BWP中一个第二BWP为有效状态。换而言之，终端设备通过前述第一配置信息和第二配置信息，确定了多个第一BWP，该多个第一BWP中包括至少两个SCS相同的第二BWP之后，终端设备仅能从该至少两个SCS相同的第二BWP中确定一个第二BWP可作为激活BWP的候选，其余的第二BWP处于无效状态(当该第二BWP处于无效状态时，可简单理解为未根据第二配置信息确定该第二BWP)。
综上所述，通过这样的配置方法可以为终端设备配置多个相关联的BWP，通过终端设备在两个相关联BWP之间进行切换的切换时延小于终端设备在两个不相关联BWP之间进行切换的切换时延的方式，降低终端设备的BWP切换时延。
