Description

一种信号传输方法及装置
本申请要求在2018年6月15日提交中国专利局、申请号为201810623140.2、申请名称为“一种信号传输方法及装置”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
本申请涉及通信技术领域，尤其涉及一种信号传输方法及装置。
背景技术
在第5代移动通信技术(the 5 th generation，5G)新空口(new radio，NR)系统中，讨论并支持通过两步资源分配方式进行基站和终端设备间的数据传输，即，基站为终端设备指示载波带宽部分(carrier bandwidth part，BWP)，并在指示的载波带宽部分中为终端设备分配资源，基站和终端设备可以在该分配的资源传输数据。
其中，基站可以为终端设备配置多个载波带宽部分，如果终端设备要工作在某个载波带宽部分，则基站需要激活该载波带宽部分。目前在同一时刻，基站只为终端设备激活一个载波带宽部分，从而基站和终端设备在该激活的载波带宽部分上传输信号。那么，如果基站为终端设备配置了多个载波带宽部分，则终端设备在工作过程中，可能需要切换工作的载波带宽部分，在切换时，终端设备和基站需要对原来工作的载波带宽部分进行去激活操作，以及对待切换的目标载波带宽部分进行激活操作，显然这些操作需要一定的时间，导致时延较大。
发明内容
本申请实施例提供一种信号传输方法及装置，用于减小终端设备在切换载波带宽部分时的时延。
第一方面，提供第一种信号传输方法，包括：在激活的第一BWP接收第一消息；根据所述第一消息确定终端设备的新激活BWP为第二BWP，其中，所述第二BWP为所述终端设备的待激活BWP中的BWP，所述终端设备针对所述终端设备的待激活BWP为射频开启状态；通过所述第二BWP传输信号。
或者，第一方面所提供的信号传输方法，还可以是：在激活的第一BWP接收第一消息；根据所述第一消息确定终端设备的新激活BWP为第二BWP，其中，所述第二BWP为所述终端设备的待激活BWP中的BWP，所述终端设备针对所述终端设备的待激活BWP为射频开启状态；从所述第一BWP切换到所述第二BWP，并通过所述第二BWP传输信号。
在本申请实施例中，在同一时刻，除了有第一BWP为激活的BWP之外，还可以有第二BWP为待激活BWP，也就是说，除了第一BWP处于激活状态外，还有第二BWP处于待激活状态，而终端设备针对终端设备的待激活BWP为射频开启状态，终端设备在切换载波带宽部分时，可以切换到待激活BWP，例如，终端设备对于待激活BWP为射频开启状态，则从激活的BWP切换到待激活BWP，可以只需要将信号从激活的BWP转移到待 激活BWP传输即可，无需再进行其他的配置操作，可以认为能够实现近似零时延的切换。可见，通过本申请实施例提供的技术方案，减小了终端设备在切换载波带宽部分时的时延，提高了通信质量。
在一种可能的实施方式中，所述方法还包括：接收第二消息，根据第二消息确定所述终端设备的待激活BWP，所述终端设备的待激活BWP为所述终端设备的BWP中的下行BWP和/或上行BWP。可选的，所述终端设备的待激活BWP为所述终端设备的BWP中的至少两个下行BWP和/或至少两个上行BWP。
可以通过第二消息确定终端设备的待激活BWP，也就是确定网络设备为终端设备配置了哪些待激活BWP，从而可以明确终端设备的配置，也可以从中确定第二BWP。
在一种可能的实施方式中，对于所述终端设备的待激活BWP中的一个BWP，所述一个BWP是所述终端设备的一个BWP组中的BWP，所述一个BWP组中可以包括K 1个上行BWP和K 2个下行BWP，K 1和K 2均为正整数。
网络设备在为终端设备配置BWP时，还可以将BWP进行分组，并为终端设备配置BWP组。例如一种分组方式为，划分的BWP组中的至少一个BWP组中的每个BWP组，都包括至少一个上行BWP和至少一个下行BWP，例如网络设备可以是根据业务类型进行的分组，不同的BWP组包括的BWP可适用于不同的业务，或者网络设备也可以有其他的分组依据，具体的不限制。
在一种可能的实施方式中，对于所述终端设备的一个BWP组，所述一个BWP组中包括至少一个上行待激活BWP和至少一个下行待激活BWP，所述至少一个上行待激活BWP和所述至少一个下行待激活BWP包括于所述终端设备的待激活BWP中，所述一个BWP组中可以包括K 3个上行BWP和K 4个下行BWP，K 3和K 4均为正整数。
如果网络设备对BWP进行了分组，那么网络设备除了分组之外，还可以为终端设备配置待激活BWP，具体的，网络设备可以为其中的至少一个BWP组配置待激活BWP，例如对于一个BWP组来说，可以包括至少一个上行待激活BWP和至少一个下行待激活BWP。所谓的待激活BWP，是指处于待激活状态的BWP。本申请实施例提出“待激活状态”的概念，处于待激活状态的BWP也可以称为待激活BWP，待激活BWP是网络设备为终端设备配置的一种状态，例如，待激活的BWP可以理解为是一个终端设备可以直接在该BWP上监听下行控制信息和/或发送接收信号的BWP，终端设备从激活BWP切换到待激活BWP，可能就只需要将信号转移到待激活BWP进行传输即可，这样，因为只需要进行信号转移，不需要进行其他的配置操作，因此切换的时延很小，甚至可以实现近似零时延的切换，从而减小了终端设备在切换BWP时的时延，提高了通信质量。
在一种可能的实施方式中，对于所述终端设备的待激活BWP中的一个上行BWP，所述一个上行BWP是所述终端设备的一个上行BWP组中的BWP，所述一个上行BWP组中可以包括K 5个上行BWP，K 5为正整数；和/或，对于所述终端设备的待激活BWP中的一个下行BWP，所述一个下行BWP是所述终端设备的一个下行BWP组中的BWP，所述一个下行BWP组中可以包括K 6个下行BWP，K 6为正整数。
这是另一种分组方式，在这种分组方式下，网络设备可以将上行BWP和下行BWP分别进行分组，则划分得到的BWP组就包括上行BWP组和/或下行BWP组，上行BWP组中包括的是上行BWP，下行BWP组中包括的是下行BWP。那么网络设备为终端设备配置的待激活BWP，可能包括上行BWP和/或下行BWP，且这些待激活BWP都属于相应的 BWP组。那么，如果网络设备为终端设备配置了上行待激活BWP，该上行待激活BWP也就是网络设备为终端设备配置的一个上行BWP组中的一个上行BWP，该上行BWP组可能包括至少一个上行BWP，如果网络设备为终端设备配置了下行待激活BWP，该下行待激活BWP也就是网络设备为终端设备配置的一个下行BWP组中的一个下行BWP，该下行BWP组可能包括至少一个下行BWP。
本文提供了网络设备的两种分组方式，在具体应用中，网络设备可根据实际情况，或者根据协议的设置，采用不同的分组方式，具体的不作限制。
在一种可能的实施方式中，对于所述终端设备的一个上行BWP组，所述一个上行BWP组中包括至少一个上行待激活BWP，所述至少一个上行待激活BWP包括于所述终端设备的待激活BWP中，所述一个上行BWP组中可以包括K 7个上行BWP，K 7为正整数；和/或，对于所述终端设备的一个下行BWP组，所述一个下行BWP组中包括至少一个下行待激活BWP，所述至少一个下行待激活BWP包括于所述终端设备的待激活BWP中，所述一个下行BWP组中可以包括K 8个下行BWP，K 8为正整数。
同样的，在这种分组方式下，网络设备除了分组之外，也是可以为终端设备配置待激活BWP，具体的，网络设备可以为其中的至少一个BWP组配置待激活BWP，这至少一个BWP组，可以均为上行BWP组，或者均为下行BWP组，或者包括上行BWP组和下行BWP组。例如对于一个上行BWP组，网络设备可以为该上行BWP组配置至少一个上行待激活BWP，再例如，对于一个下行BWP组，网络设备可以为该下行BWP组配置至少一个下行待激活BWP，具体的，对于网络设备为一个BWP组配置多少个待激活BWP，本申请实施例不作限制。配置待激活BWP，终端设备在切换时可以选择从激活BWP切换到待激活BWP，而该过程可能只需要将信号转移到待激活BWP进行传输即可，这样，因为只需要进行信号转移，不需要进行其他的配置操作，因此切换的时延很小，甚至可以实现零时延的切换，从而减小了终端设备在切换BWP时的时延，提高了通信质量。
在一种可能的实施方式中，所述方法还包括：发送能力消息，所述能力消息用于指示所述终端设备能够支持的激活BWP的数量，和/或，用于指示所述终端设备能够支持的待激活BWP的数量。
如上介绍了网络设备可以为终端设备配置BWP，那么可选地，网络设备可以根据终端设备的能力信息来为终端设备配置BWP。例如可以发送能力消息，网络设备可以获得该能力消息，通过该能力消息，网络设备可以获得终端设备的能力信息，终端设备的能力信息例如包括终端设备能够支持的激活BWP的数量以及终端设备能够支持的待激活BWP的数量中的至少一种，当然还可能包含其他的能力信息。网络设备可以根据终端设备的能力信息确定为终端设备所配置的BWP、配置的BWP组、以及配置的待激活BWP中的至少一种，还可以确定为终端设备配置的其他信息。网络设备根据终端设备的能力信息来为终端设备进行配置，可以使得配置更符合终端设备的实际情况。
在一种可能的实施方式中，通过所述第二BWP传输信号时，还包括：所述第一BWP包括于所述终端设备的待激活BWP中。
也就是，在终端设备转移到第二BWP传输信号后，可以无需将第一BWP去激活，而是继续保持第一BWP处于待激活状态，这样，如果后续终端设备又要重新转移到第一BWP传输信号，第一BWP依然是待激活BWP，则终端设备从激活BWP切换到待激活BWP，切换的时延很小，甚至可以实现零时延的切换，从而减小了终端设备在切换BWP时的时 延，提高了通信质量。
在一种可能的实施方式中，所述根据所述第一消息确定终端设备的新激活BWP，包括：根据所述第一消息中的BWP指示域确定终端设备的新激活BWP为所述第二BWP，其中，所述BWP指示域的长度是根据所述终端设备的一个BWP组中所包括的BWP的个数和所述终端设备的BWP组的个数确定的；所述终端设备的一个BWP组中所包括的BWP的个数大于或等于所述终端设备的其它BWP组中所包括的BWP的个数。
也就是，第一消息中可以包括BWP指示域，BWP指示域可以用于指示终端设备的新激活BWP，根据该指示域包括的信息就可以确定终端设备的新激活BWP，指示方式较为清楚。而且该指示域的长度也是根据该终端设备的实际配置确定的，减少了第一消息中的资源浪费，也就相应提高了资源的利用率。
第二方面，提供第二种信号传输方法，包括：在激活的第一BWP发送第一消息，所述第一消息指示终端设备的新激活BWP为第二BWP，其中，所述第二BWP为所述终端设备的待激活BWP中的BWP，所述终端设备针对所述终端设备的待激活BWP为射频开启状态；通过所述第二BWP传输信号。
在一种可能的实施方式中，所述方法还包括：发送第二消息，所述第二消息用于指示所述终端设备的待激活BWP，所述终端设备的待激活BWP为所述终端设备的BWP中的至少两个下行BWP和/或至少两个上行BWP。

在一种可能的实施方式中，对于所述终端设备的一个BWP组，所述一个BWP组中包括至少一个上行待激活BWP和至少一个下行待激活BWP，所述至少一个上行待激活BWP和所述至少一个下行待激活BWP包括于所述终端设备的待激活BWP中，所述一个BWP组中可以包括K 3个上行BWP和K 4个下行BWP，K 3和K 4均为正整数。
在一种可能的实施方式中，对于所述终端设备的待激活BWP中的一个上行BWP，所述一个上行BWP是所述终端设备的一个上行BWP组中的BWP，所述一个上行BWP组中可以包括K 5个上行BWP，K 5为正整数；和/或，对于所述终端设备的待激活BWP中的一个下行BWP，所述一个下行BWP是所述终端设备的一个下行BWP组中的BWP，所述一个下行BWP组中可以包括K 6个下行BWP，K 6为正整数。

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)，或者也可以包括第五代移动通信技术(fifth generation，5G)新无线(new radio，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(CloudRAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed ynit，DU)，本申请实施例并不限定。
3)载波带宽部分，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。一个带宽部分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)本申请实施例所述的“系统参数(numerology)”，为通信系统所采用的参数，可以是指空口(air interface)中的一系列物理层参数，通信系统(例如5G系统)可以支持多种numerology。具体实现时，可选的，一个BWP可以对应一个numerology。numerology可以包括以下参数信息中的一个或多个：子载波间隔、CP的信息、时间单位的信息以及带宽等。例如，numerology可以包括子载波间隔和CP。
以子载波间隔为例，若终端设备支持子载波间隔15kHz(kilohertz，kHz)和30kHz，则基站可以为终端设备分配一个子载波间隔为15KHz的BWP，和一个子载波间隔为30KHz的BWP，终端设备根据不同的场景和业务需求，可以切换到不同的BWP上传输数据。当终端设备支持多个BWP时，其中不同的BWP对应的numerology可以相同也可以不同。
其中，子载波间隔可以为大于等于0的整数。例如可以为15KHz、30KHz、60KHz、120KHz、240KHz、480KHz等。例如，不同的子载波间隔可以为2的整数倍。可以理解，也可以设计为其他的值。子载波间隔，是正交频分复用(orthogonal frequency division multiplexing，OFDM)系统中，频域上相邻的两个子载波的中心位置或峰值位置之间的间隔值。例如，LTE系统中的子载波间隔为15KHz，NR系统的子载波间隔可以是15kHz，或30kHz，或60kHz，或120kHz等。
关于子载波间隔，可参考如下的表1：
表1
Figure PCTCN2019090165-appb-000001

5)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。
首先，介绍本申请实施例中涉及的技术特征。
在NR系统中，讨论并支持通过两步资源分配方式进行基站和终端设备间的数据传输，即，基站先为终端设备指示BWP，再在指示的载波带宽部分中为终端设备分配资源和传输数据。
示例性地，基站为终端设备分配载波带宽部分，包括但不限于应用在以下三个场景中的至少一个：
场景一：大带宽场景。
在通信系统中，随着终端设备的业务量的增加和终端设备的数量的增加，系统业务量显著增加。因此，现有的通信系统中提出了系统带宽为大带宽的设计，用于提供较多的系统资源，从而可以提供较高的数据传输速率。在系统带宽为大带宽的通信系统中，考虑到终端设备的成本以及终端设备的业务量，终端设备支持的带宽可能小于系统带宽。其中，终端设备支持的带宽越大，终端设备的处理能力越强，终端设备的数据传输速率可能越高，终端设备的设计成本也就可能越高。终端设备支持的带宽也可以称为终端设备的带宽能力，如果终端设备是UE，那么也可以称为UE的带宽能力或UE带宽能力。示例性地，在5G系统中，系统带宽最大可能为400MHz，终端设备的带宽能力可能为20MHz、50MHz或100MHz等。在无线通信系统中，不同终端设备的带宽能力可以相同也可以不同，本申请实施例不做限制。
在系统带宽为大带宽的通信系统中，由于终端设备的带宽能力小于系统带宽，基站可以从系统频率资源中为终端设备配置载波带宽部分，该载波带宽部分的带宽可以小于等于终端设备的带宽能力。例如请参考图1，可以看到，系统带宽大于终端设备的带宽能力，而基站为终端设备配置的载波带宽部分又小于终端设备的带宽能力。当终端设备和基站进 行通信时，基站可以将为终端设备配置的载波带宽部分中的部分或全部资源分配给终端设备，用于进行基站和终端设备间的通信。
场景二：多numerology场景。
在无线通信系统中，例如5G系统中，为了支持更多的业务类型和/或通信场景，提出了支持多种numerology的设计。对于不同的业务类型和/或通信场景，可以独立设置numerology，本申请实施例中网络设备的设置也可以理解为配置。
在一种可能的配置中，基站可以在系统频域资源中配置多个载波带宽部分，并为该多个载波带宽部分中的每个载波带宽部分独立配置numerology，用于在系统频率资源中支持多种业务类型和/或通信场景。其中，不同载波带宽部分的numerology可以相同，也可以不相同。例如请参考图2，在系统带宽上，基站为终端设备配置了两个载波带宽部分，分别为BWP1和BWP2，BWP1的numerology为numerology1，BWP2的numerology为numerology2。
当UE和基站进行通信时，基站可以基于该通信对应的业务类型和/或通信场景确定用于进行通信的numerology A，从而可以基于numerology A为UE配置相应的载波带宽部分。其中，该相应的载波带宽部分的numerology被配置为numerology A。当UE和基站进行通信时，基站可以将为UE配置的载波带宽部分中的部分或全部资源分配给UE，用于进行基站和UE间的通信。
场景三：带宽回退。
当终端设备和基站进行通信时，基站可以基于终端设备的业务量为终端设备配置载波带宽部分，用于节省终端设备的功耗。示例性地，如果终端设备没有业务，则可以配置终端设备只在较小的载波带宽部分接收控制信息，例如配置终端设备在图3所示的BWP1接收控制信息，以降低终端设备的射频处理的任务量和基带处理的任务量，从而可以减少终端设备的功耗。如果终端设备的业务量较少，基站可以为终端设备配置带宽较小的载波带宽部分，例如配置终端设备在图3所示的BWP1进行业务传输，可以降低终端设备的射频处理的任务量和基带处理的任务量，从而可以减少终端设备的功耗。而如果终端设备的业务量较多，基站可以为终端设备配置带宽较大的载波带宽部分，例如配置终端设备在图3所示的BWP2进行业务传输，从而可以提供更高的数据传输速率。当终端设备和基站进行通信时，基站可以将为终端设备配置的载波带宽部分中的部分或全部资源分配给终端设备，用于进行基站和终端设备间的通信。
在如上的三种场景中，基站都可以为终端设备分配载波带宽部分，下面介绍基站如何将一个载波带宽部分配置给终端设备。
载波带宽部分的配置包括配置该载波带宽部分的频率起始资源块(resource block，RB)、带宽(bandwidth，BW)和对应的系统参数(numerology)。其中，所述带宽可以是指该载波带宽部分包括的RB的数量，所述系统参数例如包括子载波间隔、CP、或子载波间隔和CP。
在NR系统中，基站可将第一偏移、第二偏移和第三偏移发送给终端设备，从而通过这三个偏移(offset)为终端设备配置一个载波带宽部分：
第一偏移(offset1)：终端设备根据基站配置的参考频率位置(reference point)，以及相对于该参考频率位置的第一偏移，确定参考点A(reference point A)，并根据参考点A确定公共资源块(resource block，RB)的索引。参考频率位置、第一偏移和参考点A的位 置可参考图4，其中，图4是以配置两种不同的子载波间隔的BWP为例，上面一行是一种子载波间隔，例如μ＝M，下面一行是另一种子载波间隔，例如μ＝M+1。其中，不同的子载波间隔＝2 μ×15kHz，对应不同的公共RB索引，且不同的子载波间隔对应的公共RB的公共RB 0的子载波0均对应或包含该参考点A，公共RB是从公共RB 0按频率增大的方向顺序编号，那么，确定参考点A后，就可以确定参考点A所在的子载波就是公共RB的公共RB 0的子载波0。
第二偏移(offset2)：终端设备根据参考点A或公共RB 0，以及相对于参考点A或公共RB 0的第二偏移，确定虚拟载波(virtual carrier)包括的最低RB的位置。第二偏移可参考图4，虚拟载波的位置为图4中画斜线的方框所示。
第三偏移(offset3)：终端设备根据配置的BWP的最低RB的位置与虚拟载波的最低RB的位置之间的偏移(即，第三偏移)、以及配置的BWP的大小，确定配置的BWP的最低RB的位置和最高RB的位置，如图4所示的BWP的位置，图4中只示出了配置的μ＝M+1的BWP的位置。其中，所配置的BWP的大小，是基站发送给终端设备的。
在一种可能的设计中，除了配置载波带宽部分之外，要通过载波带宽部分传输信号，还需要激活载波带宽部分。目前，基站可以为终端设备配置多个载波带宽部分，但是在同一时刻，基站只为终端设备激活其中的一个载波带宽部分，从而基站和终端设备在该激活的载波带宽部分上传输信号。这里的一个载波带宽部分，可以理解为是一个上行载波带宽部分和一个下行载波带宽部分，也就是说，基站在同一时刻只为终端设备激活一个上行载波带宽部分和一个下行载波带宽部分。例如，在终端设备进行随机接入的过程中，基站可以为终端设备配置一个初始接入的载波带宽部分，并激活该载波带宽部分，保持该载波带宽部分保持激活状态。在终端设备的随机接入过程完成后，基站通过无线资源控制(radio resource control，RRC)消息为终端设备配置一个或多个载波带宽部分，基站可以通过RRC消息或下行控制信息(downlink control information，DCI)来切换不同的载波带宽部分，即，激活新的载波带宽部分，以及去激活旧的载波带宽部分。切换的方法，是在RRC消息或DCI中携带目标激活载波带宽部分的索引，从而使得终端设备进行切换。终端设备在切换时，终端设备对原来工作的载波带宽部分进行去激活操作，以及对待切换的目标载波带宽部分进行激活操作，这些操作需要一定的时间，这些时间用于改变射频的中心和/或大小等，导致切换的时延较大。
鉴于此，本申请实施例提出，在同一时刻，除了有第一BWP为激活的BWP之外，还可以有第二BWP为待激活BWP，也就是说，除了第一BWP处于激活状态外，还有第二BWP处于待激活状态，从而减小了终端设备在切换载波带宽部分时的时延，提高了通信质量。
本申请实施例提供的技术方案可以用于(但不限于)多子载波间隔的通信系统中，例如NR系统，还可以用于下一代通信系统或其他类似的通信系统。
本申请实施例的技术方案，可以考虑到未来的业务需求，在未来，一个终端设备可能需要同时待激活多个BWP，并同时在其中一个或多个BWP中进行信号传输，那么基站在一个时刻只待激活一个BWP显然是无法满足需求的。例如，基站为终端设备待激活多个载波带宽部分，包括但不限于应用在以下三个场景中的至少一个，也就是说，下面的三种场景是本申请实施例的几种可能的应用场景：
场景一：在车到一切(vehicle to everything，V2X)场景中，同时传输增强移动宽带 (enhance mobile broadband，eMBB)和超高可靠低时延通信(ultra reliable&low latency communication，URLLC)业务。
V2X包括安全相关的V2X场景，例如自动驾驶，还包括非安全相关的V2X场景，例如移动高数据率的娱乐，一些终端设备需要同时进行自动驾驶业务和资讯娱乐活动，也就是同时传输URLLC业务和eMBB业务，或者需要快速从eMBB业务切换到URLLC业务。如图5所示，终端设备需要在BWP1传输eMBB业务，以及需要在BWP2传输URLLC业务。
场景二：无许可证(unlicensed)频谱中，多个BWP同时进行先听后说(listen-before-talk，LBT)的载波侦听。
在无许可证频谱中，一个发射机需要先探听传输资源是否处于空闲状态，如果不是，需要随机回退，这导致了更大的时延和更低的用户吞吐量。那么，为了提高接入的可能性和用户吞吐量，可以把一个载波划分为多个BWP，终端设备在每个BWP上独立进行LBT，从而获的更高的接入机会和更快的切换到其他BWP上进行LBT。如图6所示，一个载波中包括多个BWP，其中包括BWP1和BWP2，终端设备可以在BWP1和BWP2上独立进行LBT。
场景三：V2X中同时传输上行Uu和副链路(sidelink)。
其中，上行Uu可以理解为终端设备向基站发送上行数据，sidelink可理解为设备到设备(device-to-device，D2D)的通信。为了提升V2X的性能，上行传输和sidelink可以在频域上频分复用或时域上时分复用，例如参考图7，BWP1可以用来向基站传输终端设备1的上行(UL)的路况报告，BWP2可以用来向终端设备2传输终端设备1的sidelink的安全相关的信息。
前文介绍了目前存在的问题，以及介绍了本申请实施例的技术方案的几种可能的应用场景，下面介绍本申请实施例所应用的一种网络架构，请参考图8。
图8中包括网络设备和终端设备，终端设备与一个网络设备连接。当然图8中的终端设备的数量只是举例，在实际应用中，网络设备可以为多个终端设备提供服务，多个终端设备中的全部终端设备或者部分终端设备都可以采用本申请实施例提供的方法向网络设备发送能力信息。
图8中的网络设备例如为接入网(access network，AN)设备，例如基站。其中，接入网设备在不同的系统对应不同的设备，例如在第四代移动通信技术(4G)系统中可以对应eNB,在第五代移动通信技术(5G)系统中对应5G中的接入网设备，例如gNB。
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信号传输方法，请参见图9A，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8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。
S91、网络设备在激活的第一BWP发送第一消息，则终端设备在激活的第一BWP接收第一消息；其中对于网络设备来说，第一消息用于指示终端设备的新激活BWP，在本实施例中，以第一消息指示的新激活BWP是第二BWP为例，其中，第二BWP为终端设备的待激活BWP中的BWP，待激活BWP对应于网络设备为终端设备配置的一种状态，也就是说，第一消息是用于指示终端设备的新激活BWP，在实际应用中，第一消息指示的既可以是待激活BWP，也可以是非待激活BWP，具体不作限制，只是本实施例以第一消息指示的是待激活BWP为例；
S92、终端设备根据第一消息确定终端设备的新激活BWP为第二BWP，其中，第二BWP为所述终端设备的待激活BWP中的BWP，待激活BWP对应于网络设备为终端设备配置的一种状态；
S93、网络设备和终端设备通过第二BWP传输信号。
网络设备和终端设备利用BWP进行无线通信时，网络设备管理系统频率资源，从系统频率资源中为终端设备分配频率资源，使得网络设备和终端设备可以利用该分配的频率资源进行通信。其中，系统频率资源可以是网络设备可以管理和分配的频率资源，还可以是可以用于进行网络设备和终端设备间的通信的频率资源。在频域，系统频域资源的宽度可以称为系统频域资源的带宽，还可以称为载波带宽、系统带宽或传输带宽。
在本申请实施例中，第一BWP可以是下行BWP，而第二BWP可以是上行BWP，也可以是下行BWP。如果第二BWP是下行BWP，那么网络设备可以在第二BWP上发送下行信号，终端设备可以在第二BWP上接收下行信号，下行信号可以包括物理下行共享信道(physical downlink shared channel，PDSCH)、同步信号、下行参考信号和物理下行控制信道(physical downlink control channel，PDCCH)中的一种或多种。或者，如果第二BWP是上行BWP，那么终端设备可以在第二BWP发送上行信号，网络设备可以在第二BWP接收上行信号，上行信号可以包括物理上行共享信道(physical uplink shared channel，PDSCH)、物理随机接入信道(physical random access channel，PRACH)、物理上行控制信道(physical uplink control channel、PUCCH)、肯定应答(acknowledgement，ACK)/否定应答(negative acknowledgement，NACK)和上行参考信号中的一种或多种。
可选地，第一消息可以是用于指示终端设备切换BWP的消息，那么第一消息可以携带新激活BWP的索引，如果站在切换的角度，也可以将新激活BWP称为目标激活BWP，而切换前的BWP，也就是第一BWP，也可以称为源BWP。终端设备接收第一消息后，通过解析第一消息就可以获得新激活BWP的索引，例如第一消息携带的是第二BWP的索引，那么新激活BWP就是第二BWP。例如第一消息可以通过RRC消息、媒体接入控制(media access control，MAC)控制元素(control element，CE)或DCI实现。
本申请实施例提出“待激活状态”的概念，处于待激活状态的BWP也可以称为待激活BWP，处于激活状态的BWP也可以称为激活BWP。待激活BWP对应于网络设备为终 端设备配置的一种状态，例如，终端设备对于终端设备的待激活BWP为射频开启状态，对此可以理解为，待激活BWP与激活BWP、配置的BWP的区别，就是激活的BWP是终端设备在当前用于监听下行控制信道的BWP，和/或激活的BWP是终端设备在当前用于接收和/或接收发送信号的BWP；待激活的BWP可以理解为是一个终端设备可以直接在该BWP上监听下行控制信息的BWP，和/或终端设备可以直接在该BWP上接收和/或发送信号的BWP，如果网络设备在当前下行控制指示中指示终端设备监听下行控制信道和/或接收发送信号的BWP为待激活BWP，那么终端设备切换BWP的时延近似为零；配置的BWP需要通过信令指示终端设备进行激活操作之后才可以在该BWP上监听下行控制信道和/或发送接收信号。那么，终端设备从激活BWP切换到待激活BWP，就只需要将信号转移到待激活BWP进行传输即可，这样，待激活BWP就变成了激活BWP。而因为只需要进行信号转移，不需要进行其他的配置操作，因此切换的时延很小，甚至可以实现近似零时延的切换，从而减小了终端设备在切换BWP时的时延，提高了通信质量。
可选地，在本申请实施里中，如果认为终端设备对于该终端设备的待激活BWP为射频开启状态，可以认为待激活BWP中包括激活BWP。
可选的，如果把激活的BWP理解为终端设备可以直接用于信号传输的BWP，比如终端设备对于激活的BWP为射频开启状态，那么本申请实施例中可以理解为网络设备为终端设备同时激活了至少两个上行和/或下行的BWP，只是同一时刻终端设备只可以在至少两个激活的BWP的中一个或多个上同时进行信号传输，那么可以理解本申请实施例中上述段落中描述的待激活BWP为激活的BWP，而上述段落中描述的激活的BWP可以理解为终端设备同一时刻进行信号传输的BWP。
前文提到了，第二BWP为终端设备的待激活BWP中的BWP，那么终端设备的待激活BWP可以包括一个或多个BWP。下面介绍，终端设备如何确定将哪些BWP设置为待激活BWP。
在本申请实施例中，网络设备还可以发送第二消息，则终端设备可以接收第二消息，第二消息可以理解为配置消息，用于网络设备向终端设备配置BWP。例如第二消息可以通过RRC消息、MAC CE或DCI实现。其中，第二消息可以是通过第一BWP传输的，也可以是通过其他BWP传输的。终端设备可以根据第二消息确定终端设备的待激活BWP，也就是确定终端设备要将网络设备配置的哪些BWP设置为待激活BWP，其中，终端设备所确定的待激活BWP，可以是网络设备为终端设备配置的BWP中的至少两个上行BWP和/或至少两个下行BWP，例如，终端设备所确定的待激活BWP，是网络设备为终端设备配置的BWP中的至少两个上行BWP和至少两个下行BWP，或者，终端设备所确定的待激活BWP，是网络设备为终端设备配置的BWP中的至少两个上行BWP，或者，终端设备所确定的待激活BWP，是网络设备为终端设备配置的BWP中的至少两个下行BWP。或者，终端设备所确定的待激活BWP，也可以是网络设备为终端设备配置的BWP中的至少一个上行BWP和/或至少一个下行BWP，例如，终端设备所确定的待激活BWP，是网络设备为终端设备配置的BWP中的至少一个上行BWP和至少一个下行BWP，或者，终端设备所确定的待激活BWP，是网络设备为终端设备配置的BWP中的至少一个上行BWP，或者，终端设备所确定的待激活BWP，是网络设备为终端设备配置的BWP中的至少一个下行BWP。在这种情况下，所述的至少两个上行BWP可以包括在所述的至少一个上行BWP中，所述的至少两个下行BWP可以包括在所述的至少一个下行BWP中。
在本申请实施例中，主要以终端设备所确定的待激活BWP是网络设备为终端设备配置的BWP中的至少两个上行BWP和/或至少两个下行BWP为例来介绍。
例如，一个小区内有一个载波或多个载波，网络设备可以为终端设备在其中的至少一个载波上为终端设备配置一个或多个BWP，如图10A所示，为网络设备在一个载波上为终端设备配置了两个BWP，如图10B所示，为网络设备在两个载波中的每个载波上为终端设备配置了一个BWP。例如网络设备可以通过第二消息一并为终端设备配置BWP，或者也可以通过其他的消息为终端设备配置BWP，本文以网络设备通过第二消息为终端设备配置BWP为例。其中，网络设备配置BWP的具体方式可参考前文的介绍，不多赘述。网络设备在为终端设备配置BWP时，可以为终端设备配置上行BWP和/或下行BWP，上行BWP用于终端设备向网络设备发送信号，下行BWP用于网络设备向终端设备发送信号。
在本申请实施例中，网络设备为终端设备配置的BWP可以包括N个上行BWP和/或M个下行BWP，例如网络设备为终端设备配置的BWP包括N个上行BWP和M个下行BWP，或者，网络设备为终端设备配置的BWP包括N个上行BWP，或者，网络设备为终端设备配置的BWP包括M个下行BWP，N和M均为正整数，例如N和M均为大于或等于2的整数。其中，网络设备为终端设备配置的BWP中包括了终端设备根据第二消息所确定的待激活BWP，网络设备为终端设备配置的BWP的数量，也就是N+M的值，可以大于或等于终端设备根据第二消息所确定的待激活BWP的数量。
在本申请实施例中，网络设备在确定为终端设备配置的N个上行BWP和/或M个下行BWP后，可以直接将N个上行BWP和/或M个下行BWP配置给终端设备，或者也可以对N个上行BWP和/或M个下行BWP进行分组，得到P个BWP组，再以BWP组的形式为终端设备进行配置，其中，P为正整数。例如，网络设备可以通过第二消息为终端设备配置P个BWP组，或者也可以通过其他消息为终端设备配置P个BWP组。下面就根据网络设备对BWP进行分组或不进行分组的情况，分别进行介绍。
一、在本申请实施例中，网络设备对确定配置给终端设备的N个上行BWP和/或M个下行BWP进行分组。
其中，网络设备可以采用多种分组方式，本文介绍两种，本领域技术人员可以明确的是，本实施例不限制具体的分组方式。
1、第一种分组方式。
在第一种分组方式下，网络设备通过P个BWP组的形式为终端设备配置N+M个BWP，或者网络设备将确定为终端设备配置的N+M个BWP划分为P个BWP组，该P个BWP组中的一个BWP组可以包括至少一个上行BWP和至少一个下行BWP。其中，不同的BWP组包括的上行BWP的数量可以相同也可以不同，不同的BWP组包括的下行BWP的数量可以相同也可以不同。
作为一种实施方式，网络设备可以根据业务的类型来进行分组，例如一个BWP组包括的BWP可以适用于一种类型的业务。例如，网络设备确定为终端设备配置4个上行BWP和4个下行BWP，网络设备将这4个上行BWP和4个下行BWP分成两个BWP组，每个BWP组中包括2个上行BWP和2个下行BWP。其中第一个组包括的BWP适用于传输第一种类型的业务，例如eMBB业务，第二个组中的BWP适用于传输第二种类型的业务，例如URLLC业务。这个示例是以不同的BWP组包括的上行BWP的数量相同、以及不同的BWP组包括的下行BWP的数量也相同为例，具体的不限于此。
当然，网络设备在分组时，除了根据业务的类型来分组之外，也可以根据其他因素来分组，具体的不作限制。
作为一种实施方式，网络设备除了为终端设备配置BWP组之外，还可以为其中的至少一个BWP组中的每个BWP组配置至少一个上行待激活BWP和至少一个下行待激活BWP，至少一个上行待激活BWP和至少一个下行待激活BWP都包括在网络设备确定的终端设备的待激活BWP中。例如，网络设备可以通过第二消息为P个BWP组中的至少一个BWP组配置至少一个上行待激活BWP和至少一个下行待激活BWP，或者也可以通过其他消息为P个BWP组中的至少一个BWP组配置至少一个上行待激活BWP和至少一个下行待激活BWP。在前文介绍了，网络设备为终端设备配置了至少两个上行BWP和/或至少两个下行BWP为待激活BWP，至少两个上行BWP和至少两个下行BWP都属于网络设备为终端设备配置的BWP，那么在第一种分组方式下，至少一个BWP组所包括的所有的上行待激活BWP的总数，就等于网络设备所配置的作为待激活BWP的至少两个上行BWP的总数，至少一个BWP组所包括的所有的下行待激活BWP的总数，就等于网络设备所配置的作为待激活BWP的至少两个下行BWP的总数。
作为该实施方式的一种特例，网络设备可以为P个BWP组中的至少一个BWP组中的每个BWP组配置一个上行待激活BWP和一个下行待激活BWP。网络设备给终端设备配置了一个下行载波和一个上行载波，网络设备在该上行载波上为终端设备配置了一个或多个上行BWP，以及在下行载波上为终端设备配置了一个或多个下行BWP。网络设备还为终端设备配置BWP组，例如每个BWP组可以包括下行载波上的一个或多个下行BWP，和包括上行载波上的一个或多个上行BWP。如果对于这样的一个BWP组，则网络设备可以将其中的一个上行BWP设置为上行待激活BWP，以及将其中的一个下行BWP设置为下行待激活BWP。
或者，上行载波还有一种特例，即，增补上行(supplementary(supplemental)UL，SUL)载波。那么，作为该实施方式的另一种特例，网络设备可以为P个BWP组中的至少一个BWP组中的每个BWP组配置两个上行待激活BWP和一个下行待激活BWP。例如，网络设备给终端设备配置了一个下行载波，一个上行载波和一个SUL载波，网络设备在该上行载波上为终端设备配置了一个或多个上行BWP，在SUL载波上为终端设备配置了一个或多个上行BWP，为了相区分，将其称为上行SUL BWP，以及在下行载波上为终端设备配置了一个或多个下行BWP。网络设备还为终端设备配置BWP组，例如每个BWP组可以包括下行载波上的一个或多个下行BWP，可以包括上行载波上的一个或多个上行BWP，还可以包括SUL载波上的一个或多个上行SUL BWP。如果对于这样的一个BWP组，则网络设备可以将其中的一个上行BWP设置为上行待激活BWP，将其中的一个上行SUL BWP设置为上行待激活BWP，以及将其中的一个下行BWP设置为下行待激活BWP。也就是，两个上行待激活BWP分别是上行BWP和上行SUL BWP。
可选地，网络设备为一个BWP组配置的上行待激活BWP的数量小于或等于该BWP组包括的上行BWP的数量，网络设备为一个BWP组配置的下行待激活BWP的数量小于或等于该BWP组包括的下行BWP的数量。在一个BWP组中，除了至少一个上行待激活BWP和至少一个下行待激活BWP之外，如果还包括其他的BWP，则其他的BWP就是处于非待激活状态的BWP，或者称为非待激活BWP，终端设备针对终端设备的非待激活BWP，可以是射频关闭状态。可以理解为，终端设备如果要从激活的BWP切换到待激活BWP， 则可能只需将信号转移到待激活BWP即可，无需进行其他的设置操作，而终端设备如果要从激活的BWP切换到非待激活BWP，则需要对非待激活BWP进行激活操作，在激活操作之后才能将信号转移到被激活的非待激活BWP，显然需要的时间较长。
可选地，在一个BWP组中配置至少一个上行待激活BWP和至少一个下行待激活BWP，是为了终端设备在切换到该BWP组时，能够直接切换到至少一个上行待激活BWP中的一个上行待激活BWP，或切换到至少一个下行待激活BWP中的一个下行待激活BWP，无需再进行过多的选择BWP的操作，节省信令的开销。
终端设备在接收网络设备的配置后，可以确定P个BWP组，例如终端设备可以获知P个BWP组中的每个BWP组的信息，BWP组的信息例如为BWP组的标识或索引，终端设备还可以获知每个BWP组包括的所有的BWP的信息，BWP的信息例如包括BWP的索引或标识。
可选地，网络设备的配置过程可以是在终端设备的初始随机接入过程中进行的，也就是说，第二消息(或者还有其他的配置消息)可以是在终端设备的初始随机接入过程中传输的，或者，网络设备的配置过程也可以是在终端设备的初始随机接入过程完成之后进行的，也就是说，第二消息(或者还有其他的配置消息)可以是在终端设备的初始随机接入过程之后传输的，例如第二消息为终端设备的初始随机接入完成之后的RRC消息。
可选地，终端设备在接收网络设备的配置后，就拥有网络设备配置的N个上行BWP和M个下行BWP，这些BWP属于P个BWP组。进一步的，该P个BWP组中，还可以有至少一个BWP组中的每个BWP组中包括至少一个上行待激活BWP和至少一个下行待激活BWP，上行待激活BWP，也就是处于待激活状态的上行BWP，下行待激活BWP，也就是处于待激活状态的下行BWP。
可选地，作为一种特例，网络设备可以为P个BWP组中的至少一个BWP组中的每个BWP组配置一个上行待激活BWP和一个下行待激活BWP。例如，终端设备完成初始随机接入后，网络设备为终端设备配置了4个上行BWP，分别为上行BWP0～上行BWP3，以及配置了4个下行BWP，分别为下行BWP0～下行BWP3，并为终端设备配置了两个BWP组，BWP组0中包含上行BWP0、上行BWP1、下行BWP0和下行BWP1，BWP组1中包含上行BWP2、下行BWP3、下行BWP2和下行BWP3。其中，网络设备还配置了，上行BWP0为BWP组0中的上行待激活BWP，下行BWP0为BWP组0中的待激活的下行BWP，上行BWP3为BWP组1中的待激活上行BWP，下行BWP3为BWP组1中的激活下行BWP。那么终端设备接收网络设备的配置后，可以确定上行BWP0～上行BWP3、下行BWP0～下行BWP3、以及BWP组0和BWP组1的信息，还可以确定上行BWP0、下行BWP0、上行BWP3和下行BWP3均为待激活BWP。
可选地，作为另一种特例，网络设备可以为其中的至少一个BWP组中的每个BWP组配置两个上行待激活BWP和一个下行待激活BWP。例如，终端设备完成初始随机接入后，网络设备为终端设备配置了6个上行BWP，其中在上行载波上配置了4个BWP，分别为上行BWP0～上行BWP3，在SUL载波上配置了2个上行BWP，分别为上行BWP4～上行BWP5，以及在下行载波上配置了4个下行BWP，分别为下行BWP0～下行BWP3，并为终端设备配置了两个BWP组，BWP组0中包含上行载波上的上行BWP0、上行BWP1，SUL载波上的上行BWP4，以及下行载波上的下行BWP0和下行BWP1，BWP组1中包含上行载波上的上行BWP2、上行BWP3，SUL载波上的上行BWP5，以及下行载波上的下行BWP2 和下行BWP3。其中，网络设备还配置了，上行载波上的上行BWP0和SUL载波上的上行BWP4为BWP组0中的上行待激活BWP，下行载波上的下行BWP0为BWP组0中的待激活的下行BWP，上行载波上的上行BWP3和SUL载波上的上行BWP5为BWP组1中的待激活上行BWP，下行载波上的BWP3为BWP组1中的激活下行BWP。那么终端设备接收网络设备的配置后，可以确定上行载波上的上行BWP0～上行BWP3、SUL载波上的上行BWP4～上行BWP5、下行载波上的下行BWP0～下行BWP3、以及BWP组0和BWP组1的信息，还可以确定上行载波上的上行BWP0、SUL载波上的上行BWP4、下行载波上的BWP0、上行载波上的上行BWP3、SUL载波上的上行BWP5和下行载波上的下行BWP3均为待激活BWP。
可选地，终端设备接收第二消息后，可以根据第二消息确定终端设备的待激活BWP，而在前文也介绍了，网络设备还可以为终端设备配置P个BWP组，那么终端设备也可以确定，终端设备的待激活BWP中的每个BWP都属于相应的BWP组，例如对于终端设备的待激活BWP中的一个BWP，该BWP可以是终端设备的一个BWP组中的BWP，该BWP可以是第二BWP，也可以是其他的待激活BWP，这一个BWP组中例如包括K 1个上行BWP和K 2个下行BWP，K 1和K 2均为正整数，K 1和K 2可以相等，也可以不相等。另外，如果网络设备还为P个BWP组中的至少一个BWP组中的每个BWP组配置了至少一个上行待激活BWP和至少一个下行待激活BWP，那么终端设备可以确定，对于P个BWP组中的至少一个BWP组中的一个BWP组来说，这个BWP组中可以包括至少一个上行待激活BWP和至少一个下行待激活BWP，这至少一个上行待激活BWP和至少一个下行待激活BWP包括于终端设备的待激活BWP中，也就是说，这至少一个上行待激活BWP和至少一个下行待激活BWP都属于终端设备的待激活BWP，这个BWP组中例如包括K 3个上行BWP和K 4个下行BWP，K 3和K 4均为正整数，K 3和K 4可以相等，也可以不相等。另外，这个BWP组与前文中的包括K 1个上行BWP和K 2个下行BWP的BWP组，可以是同一个BWP组，那么K 1＝K 3，K 4＝K 2，或者，这两个BWP组也可以是不同的BWP组，那么，K 1和K 3可以相等，也可以不相等，K 4和K 2可以相等，也可以不相等。
在本申请实施例中，网络设备为终端设备配置P个BWP组时，可以指示终端设备，全部的BWP组或其中的部分BWP组被配置为待激活状态，例如网络设备可以通过第二消息或其他消息指示终端设备全部的BWP组或其中的部分BWP组为待激活状态。其中，将一个BWP组设置为待激活状态，可以是指将该BWP组包括的全部BWP或部分BWP设置为待激活状态，例如，网络设备还为P个BWP组中的至少一个BWP组中的每个BWP组配置了至少一个上行待激活BWP和至少一个下行待激活BWP，那么这至少一个BWP组就可以认为被网络设备设置为了待激活状态。对于终端设备来说也是同样，例如网络设备还为P个BWP组中的至少一个BWP组中的每个BWP组配置了至少一个上行待激活BWP和至少一个下行待激活BWP，则网络设备可以指示终端设备也设置P个BWP组中的至少一个BWP组中的每个BWP组中的至少一个上行待激活BWP和至少一个下行待激活BWP为待激活状态，也就是，对于终端设备来说，也就是将这至少一个BWP组设置为了待激活状态。
可选地，如果网络设备在至少一个BWP组中的每个BWP组中设置了一个上行待激活BWP和一个下行待激活BWP，或者设置了两个上行待激活BWP和一个下行待激活BWP，其中的两个上行待激活BWP包括一个处于待激活状态的上行BWP和一个处于待激活状态 的上行SUL BWP，那么，网络设备和终端设备可以将至少两个BWP组设置为待激活状态，而如果网络设备在至少一个BWP组中的一个或多个BWP组中设置了多个上行待激活BWP和/或多个下行待激活BWP，那么网络设备和终端设备可以将至少一个BWP组设置为待激活状态，总之可以保证，终端设备的待激活BWP为终端设备的BWP中的至少两个下行BWP和/或至少两个上行BWP。
例如网络设备在配置P个BWP组后，将全部的P个BWP组均设置为了待激活状态，则根据网络设备的指示，终端设备也将全部的P个BWP组均设置为了待激活状态，且设置为待激活状态的方式为，对于P个BWP组中不包括上行SUL BWP的BWP组，网络设备为其中的每个BWP组设置了一个上行待激活BWP和一个下行待激活BWP，对于P个BWP组中包括上行SUL BWP的BWP组，网络设备为其中的每个BWP组设置了两个上行待激活BWP和一个下行待激活BWP，这两个上行待激活BWP，包括一个设置为待激活状态的上行BWP和一个设置为待激活状态的上行SUL BWP。那么作为一种示例，网络设备所发送的第一消息，可以无需指示具体的新激活BWP的索引，而是可以指示BWP组的信息，例如BWP组的标识或索引，终端设备确定了BWP组，就可以默认直接切换到该BWP组的上行待激活BWP和下行待激活BWP，而无需再一一确定待切换的BWP，方便了终端设备的操作。其中，如果涉及到切换，那么S93也可以理解为，终端设备切换到第二BWP，网络设备和终端设备通过第二BWP传输信号，因此，图9A所示的实施例，其对应的流程图也可参考图9B，在图9B中，S93包括两个过程，一个过程是终端设备从第一BWP切换到第二BWP，另一个过程是终端设备和网络设备通过第二BWP传输信号，图9B的S91与图9A的S91可以是相同的步骤，图9B的S92与图9A的S92可以是相同的步骤。而终端设备切换到第二BWP后，第二BWP也就从待激活状态转为激活状态，也就是，第二BWP变成了激活BWP，因此也可以认为，是终端设备激活了第二BWP。
例如，终端设备完成初始随机接入后，网络设备为终端设备配置了4个上行BWP，分别为上行BWP0～上行BWP3，以及配置了4个下行BWP，分别为下行BWP0～下行BWP 3，并为终端设备配置了两个BWP组，BWP组0中包含上行BWP0、上行BWP1、下行BWP0和BWP1，BWP组1中包含上行BWP2、BWP3、下行BWP2和BWP3。且网络设备配置上行BWP0为BWP组0中的上行待激活BWP，下行BWP0为组0中的下行待激活BWP，以及配置上行BWP3为BWP组1中的上行待激活BWP，下行BWP3为BWP组1中的下行待激活BWP。例如终端设备初始工作在BWP组0，也就是工作在上行BWP0或下行BWP0，那么网络设备向终端设备发送第一消息，第一消息指示新激活BWP的方式例如是指示BWP组的信息，例如第一消息指示的是BWP组1的索引，那么终端设备就确定待切换的目标BWP位于BWP组1中，则终端设备默认切换到BWP组1中的上行BWP3或下行BWP3，可以认为无需额外从网络设备获取BWP的索引。
作为一种特例，网络设备给终端设备配置了一个下行载波，一个上行载波和一个SUL载波，网络设备在该上行载波上为终端设备配置了一个或多个上行BWP，在SUL载波上为终端设备配置了一个或多个上行SUL BWP，以及在下行载波上为终端设备配置了一个或多个下行BWP。网络设备还为终端设备配置BWP组，例如每个BWP组可以包括下行载波上的一个或多个下行BWP，可以包括上行载波上的一个或多个上行BWP，还可以包括SUL载波上的一个或多个上行SUL BWP。对于这样的一个BWP组，网络设备可以将其中的一个上行BWP设置为上行待激活BWP，将其中的一个上行SUL BWP设置为上行 待激活BWP，以及将其中的一个下行BWP设置为下行待激活BWP。也就是，两个上行待激活BWP分别是上行BWP和上行SUL BWP。那么对于这样的BWP组，网络设备在指示终端设备切换上行BWP时，可以一并指示载波的标识，例如网络设备可以通过第一消息指示BWP组的标识以及指示待切换的目标上行待激活BWP所在的载波的标识，以指示终端设备待切换的目标上行BWP在哪一个上行载波上。
例如网络设备在配置P个BWP组后，将全部的P个BWP组或部分的BWP组设置为了待激活状态，则在与终端设备通信的期间，网络设备可以一直保持这些BWP组处于待激活状态，当然网络设备也可以指示终端设备一直保持这些BWP组处于待激活状态。其中，BWP组保持待激活状态，可以是指该BWP组中有至少一个BWP保持待激活状态，即，终端设备针对这至少一个BWP为射频开启状态。
网络设备如果在配置BWP组后将其中的部分BWP组设置为了待激活状态，那么在通信过程中网络设备也可以更新设置为待激活状态的BWP组，且网络设备可以通过消息通知终端设备更新设置为待激活状态的BWP组，该消息例如为RRC消息、MAC CE或DCI。其中，更新可以包括，将之前未设置为待激活状态的BWP组设置为待激活状态，和/或将之前设置为待激活状态的BWP组设置为非待激活状态。其中，本文中所述的非待激活状态，或称为非激活状态，是指既不是激活状态也不是待激活状态，对于处于这种状态的BWP，如果要激活，那么就需要进行激活操作。
可选地，前文所述的第一种分组方式可以适用于对称频谱系统和非对称频谱系统。对于非对称频谱系统，上行待激活BWP和下行待激活BWP的频域中心位置对齐，是一个BWP对，终端设备激活其中的一个BWP，那么会同时激活另外一个BWP，例如，终端设备的下行BWP从BWP组1中的下行BWP切换到BWP组2中的下行BWP，其对应的上行BWP也需要切换到BWP组2中上行BWP配对的上行BWP。对于对称频谱系统，上行BWP和下行BWP可以独立激活和待激活，例如，终端设备的下行BWP从BWP组1中的下行BWP切换到BWP组2中的下行BWP，而终端设备的上行BWP可以切换也可以不切换，由网络设备确定，如果终端设备的上行BWP也需要切换，那么网络设备可以一并在第一消息中指示待切换的目标上行BWP。
或者，对于非对称频谱系统和对称频谱系统，都可以选择将终端设备的上行BWP和下行BWP进行配对，那么网络设备配置给终端设备的N个上行BWP和M个下行BWP中就包括了多个BWP对。例如其中的下行BWP1和上行BWP1是一对，下行BWP2和上行BWP2是一对，那么在终端设备的下行BWP从下行BWP1切换到下行BWP2后，终端设备的上行BWP也需要从上行BWP1切换到上行BWP2。那么网络设备在分组时，可以将下行BWP1和上行BWP1分到一个BWP组，以及将下行BWP2和上行BWP2分到一个BWP组，还可以将下行BWP2设置为所在的BWP组中的下行待激活BWP，以及将上行BWP2设置为所在的BWP组中的上行待激活BWP，这样终端设备就可以直接进行BWP组的切换。
在第一种分组方式下，一个BWP组既包括上行BWP也包括下行BWP，下面再介绍本申请实施提供的第二种分组方式。
2、第二种分组方式。
在本申请实施例中，在第二种分组方式下，网络设备可以通过D个BWP组的方式为终端设备配置的N+M个BWP，或者网络设备可以将确定为终端设备配置的N+M个BWP 划分为D个BWP组，该D个BWP组中的一个BWP组可以包括至少一个上行BWP，或包括至少一个下行BWP，也就是，可以认为D个BWP组包括至少一个上行BWP组和至少一个下行BWP组。其中，不同的上行BWP组包括的上行BWP的数量可以相同也可以不同，不同的下行BWP组包括的下行BWP的数量可以相同也可以不同。
作为一种实施方式，网络设备可以直接将配置给终端设备的所有的上行BWP分为一个BWP组，以及将配置给终端设备的所有的下行BWP分为一个BWP组。例如，网络设备确定为终端设备配置4个上行BWP和4个下行BWP，分别为上行BWP0～上行BWP3，下行BWP0～下行BWP3。网络设备可以将这4个上行BWP和4个下行BWP分成一个上行BWP组和一个下行BWP组，其中的BWP组0为上行BWP组，包括上行BWP0、～上行BWP3，BWP组1为下行BWP组，包括下行BWP0～下行BWP3。
作为另一种实施方式，网络设备也可以根据业务的类型来进行分组，例如一个BWP组包括的BWP可以适用于一种类型的业务。例如，网络设备确定为终端设备配置4个上行BWP和4个下行BWP，分别为上行BWP0～上行BWP3，下行BWP0～下行BWP3。网络设备将这4个上行BWP和4个下行BWP分成两个上行BWP组和两个下行BWP组，其中的BWP组0包括上行BWP0～上行BWP1，BWP组1包括上行BWP2～上行BWP3，BWP组2包括下行BWP0～下行BWP1，BWP组3包括下行BWP2～下行BWP3。其中BWP组0包括的BWP和BWP组2适用于传输第一种类型的业务，例如eMBB业务，BWP组1和BWP组3中的BWP适用于传输第二种类型的业务，例如URLLC业务。这个示例是以不同的上行BWP组包括的上行BWP的数量相同、以及不同的下行BWP组包括的下行BWP的数量也相同为例，具体的不限于此。
或者，网络设备在分组时，除了根据业务的类型来分组之外，还可以根据其他因素来分组，具体的不作限制。
在本申请实施例中，网络设备除了为终端设备配置BWP组之外，也可以为D个BWP组中的至少一个上行BWP组中的每个上行BWP组配置至少一个上行待激活BWP，和/或，可以为D个BWP组中的至少一个下行BWP组中的每个下行BWP组配置至少一个下行待激活BWP。例如，网络设备可以为D个BWP组中的至少一个上行BWP组中的每个上行BWP组配置至少一个上行待激活BWP，或，网络设备可以为D个BWP组中的至少一个下行BWP组中的每个下行BWP组配置至少一个下行待激活BWP，或，网络设备可以为D个BWP组中的至少一个上行BWP组中的每个上行BWP组配置至少一个上行待激活BWP，以及为D个BWP组中的至少一个下行BWP组中的每个下行BWP组配置至少一个下行待激活BWP。如果网络设备为D个BWP组中的至少一个上行BWP组中的每个上行BWP组配置至少一个上行待激活BWP，则至少一个上行待激活BWP包括在网络设备确定的终端设备的待激活BWP中，如果网络设备为D个BWP组中的至少一个下行BWP组中的每个下行BWP组配置至少一个下行待激活BWP，则至少一个下行待激活BWP也包括在网络设备确定的终端设备的待激活BWP中。
例如，网络设备可以通过第二消息为D个BWP组中的至少一个上行BWP组中的每个上行BWP组配置至少一个上行待激活BWP，和/或，为D个BWP组中的至少一个下行BWP组中的每个下行BWP组配置至少一个下行待激活BWP，或者也可以通过其他消息为D个BWP组中的至少一个上行BWP组中的每个上行BWP组配置至少一个上行待激活BWP，和/或，D个BWP组中的至少一个下行BWP组中的每个下行BWP组配置至少一 个下行待激活BWP。在前文介绍了，网络设备为终端设备配置了至少两个上行BWP和/或至少两个下行BWP为待激活BWP，那么在第二种分组方式下，D个BWP组中的至少一个上行BWP组所包括的所有的上行待激活BWP的总数，就等于网络设备所配置的作为待激活BWP的至少两个上行BWP的总数，D个BWP组中的至少一个BWP组中的至少一个下行BWP组所包括的所有的下行待激活BWP的总数，就等于网络设备所配置的作为待激活BWP的至少两个下行BWP的总数。
可选地，网络设备配置的待激活BWP可以都是上行BWP，那么网络设备可以只将一个上行BWP组中的至少两个上行BWP配置为上行待激活BWP，或者可以将多个上行BWP组中的每个BWP组中的一个或多个上行BWP配置为上行待激活BWP。或者，网络设备配置的待激活BWP可以都是下行BWP，那么网络设备可以只将一个下行BWP组中的至少两个下行BWP配置为下行待激活BWP，或者可以将多个下行BWP组中的每个下行BWP组中的一个或多个下行BWP配置为下行待激活BWP。或者，网络设备配置的待激活BWP可以包括上行BWP和下行BWP，那么网络设备可以将一个上行BWP组中的至少两个上行BWP配置为上行待激活BWP，以及将一个下行BWP组中的至少两个下行BWP配置为下行待激活BWP，或者可以将多个上行BWP组中的每个BWP组中的一个或多个上行BWP配置为上行待激活BWP，以及将多个下行BWP组中的每个下行BWP组中的一个或多个下行BWP配置为下行待激活BWP。
作为该实施方式的一种特例，网络设备可以为D个BWP组中的至少一个上行BWP组中的每个上行BWP组配置一个上行待激活BWP，以及为D个BWP组中的至少一个下行BWP组中的每个下行BWP组配置一个下行待激活BWP。例如，网络设备给终端设备配置了一个下行载波和一个上行载波，网络设备在该上行载波上为终端设备配置了一个或多个上行BWP，以及在下行载波上为终端设备配置了一个或多个下行BWP。网络设备还为终端设备配置BWP组，例如配置了一个或多个上行BWP组以及一个或多个下行BWP组，其中的每个上行BWP组包括至少一个上行BWP，其中的每个下行BWP组包括至少一个下行BWP。对于其中的至少一个上行BWP组，则网络设备可以将其中的每个BWP组中的一个上行BWP设置为上行待激活BWP，对于其中的至少一个下行BWP组，网络设备可以将其中的每个BWP组中的一个下行BWP设置为下行待激活BWP。
或者，上行载波还有一种特例，即，SUL载波。那么，作为该实施方式的另一种特例，网络设备可以为D个BWP组中的至少一个上行BWP组中的每个上行BWP组配置两个上行待激活BWP，以及为D个BWP组中的至少一个下行BWP组中的每个下行BWP组配置一个下行待激活BWP，这里的至少一个上行BWP组中的每个上行BWP组可以既包括上行载波上的上行BWP也包括SUL载波上的上行BWP。例如，网络设备给终端设备配置了一个下行载波、一个上行载波和一个SUL载波，网络设备在该上行载波上为终端设备配置了一个或多个上行BWP，在下行载波上为终端设备配置了一个或多个下行BWP，以及在该SUL载波上为终端设备配置了一个或多个上行SUL BWP。网络设备还为终端设备配置BWP组，例如配置了一个或多个上行BWP组以及一个或多个下行BWP组，其中可能有部分上行BWP组包括至少一个上行BWP，还可能有部分上行BWP组包括至少一个上行BWP和至少一个上行SUL BWP，其中的每个下行BWP组包括至少一个下行BWP。对于其中的包括了上行SUL BWP的上行BWP组，则网络设备可以将其中的每个BWP组中的一个上行载波上的上行BWP设置为上行待激活BWP，以及将其中的每个BWP组中的 一个上行SUL BWP设置为上行待激活BWP，则一个上行BWP组就包括两个上行待激活BWP，以及，对于其中的至少一个下行BWP组，网络设备还可以将其中的每个BWP组中的一个下行BWP设置为下行待激活BWP。
可选地，网络设备为一个上行BWP组配置的上行待激活BWP的数量小于或等于该上行BWP组包括的上行BWP的数量，网络设备为一个下行BWP组配置的下行待激活BWP的数量小于或等于该下行BWP组包括的下行BWP的数量。在一个上行BWP组中，除了至少一个上行待激活BWP之外，如果还包括其他的上行BWP，则其他的上行BWP就是处于非待激活状态的上行BWP，或者称为上行非待激活BWP，同理，在一个下行BWP组中，除了至少一个下行待激活BWP之外，如果还包括其他的下行BWP，则其他的下行BWP就是处于非待激活状态的下行BWP，或者称为下行非待激活BWP，终端设备针对终端设备的上行非待激活BWP和下行非待激活BWP，可以是射频关闭状态。
其中，在一个上行BWP组中配置至少一个上行待激活BWP，是为了终端设备在切换到该上行BWP组时，能够直接切换到至少一个上行待激活BWP中的一个上行待激活BWP，同理，在一个下行BWP组中配置至少一个下行待激活BWP，是为了终端设备在切换到该上行BWP组时，能够直接切换到至少一个下行待激活BWP中的一个下行待激活BWP，可能无需再进行过多的选择BWP的操作。
终端设备在接收网络设备的配置后，可以确定D个BWP组，例如终端设备可以确定D个BWP组中的每个BWP组的信息，BWP组的信息例如为BWP组的标识或索引，终端设备还可以获知每个BWP组包括的所有的BWP的信息，BWP的信息例如包括BWP的索引或标识。如果网络设备还为D个BWP组中的至少一个上行BWP组中的每个上行BWP组配置至少一个上行待激活BWP，那么终端设备在接收网络设备的配置后，也将确定D个BWP组中的至少一个上行BWP组中的每个上行BWP组中的至少一个上行待激活BWP的索引或标识，如果网络设备还为D个BWP组中的至少一个下行BWP组中的每个下行BWP组配置至少一个下行待激活BWP，那么终端设备在接收网络设备的配置后，也将确定D个BWP组中的至少一个下行BWP组中的每个下行BWP组中的至少一个下行待激活BWP的索引或标识。
可选地，网络设备的配置过程可以是在终端设备的初始随机接入过程中进行的，也就是说，第二消息(或者还有其他的配置消息)可以是在终端设备的初始随机接入过程中传输的，或者，网络设备的配置过程也可以是在终端设备的初始随机接入过程完成之后进行的，也就是说，第二消息(或者还有其他的配置消息)可以是在终端设备的初始随机接入过程完成之后传输的，例如第二消息为终端设备的初始随机接入过程完成之后传输的RRC消息。当然该配置过程也可以发生在终端设备的初始随机接入完成之后的其他任意时间段，具体的不作限制。
根据前文的介绍可知，终端设备在接收第二消息后，可以确定网络设备配置的N个上行BWP和M个下行BWP，这些BWP属于D个BWP组。进一步的，该D个BWP组中，还可以有至少一个上行BWP组中的每个上行BWP组包括至少一个上行待激活BWP，或者可以有至少一个下行BWP组中的每个下行BWP组包括至少一个下行待激活BWP，或者可以有至少一个上行BWP组中的每个上行BWP组包括至少一个上行待激活BWP，以及至少一个下行BWP组中的每个下行BWP组包括至少一个下行待激活BWP。
可选地，作为一种特例，网络设备可以为D个BWP组中的至少一个上行BWP组中 的每个上行BWP组配置一个上行待激活BWP，以及为D个BWP组中的至少一个下行BWP组中的每个下行BWP组配置一个下行待激活BWP。例如，终端设备完成初始随机接入后，网络设备为终端设备配置了4个上行BWP，分别为上行BWP0～上行BWP3，以及配置了4个下行BWP，分别为下行BWP0～下行BWP3，并为终端设备配置了两个上行BWP组和两个下行BWP组，两个上行BWP组为上行BWP组0和上行BWP组1，上行BWP组0中包含上行BWP0和上行BWP1，上行BWP组1中包含上行BWP2和上行BWP3，两个下行BWP组为下行BWP组0和下行BWP组1，下行BWP组0中包含下行BWP0和下行BWP1，下行BWP组1中包含下行BWP2和下行BWP3。其中，网络设备还配置了，上行BWP0为上行BWP组0中的上行待激活BWP，上行BWP3为上行BWP组1中的上行待激活BWP，下行BWP0为下行BWP组0中的下行待激活BWP，下行BWP3为下行BWP组1中的下行待激活BWP。那么终端设备接收网络设备的配置后，可以确定上行BWP0～上行BWP3、下行BWP0～下行BWP3、以及上行BWP组0、上行BWP组1、下行BWP组0和下行BWP组1的信息，还可以将上行BWP0、下行BWP0、上行BWP3和下行BWP3均设置为待激活BWP。
可选地，作为另一种特例，网络设备可以为D个BWP组中的至少一个上行BWP组中的每个上行BWP组配置两个上行待激活BWP，以及为D个BWP组中的至少一个下行BWP组中的每个下行BWP组配置一个下行待激活BWP，这里的至少一个上行BWP组中的每个上行BWP组都既包括上行载波上的上行BWP也包括SUL载波上的上行BWP。例如，终端设备完成初始随机接入后，网络设备为终端设备配置了6个上行BWP，其中在上行载波上配置了4个BWP，分别为上行BWP0～上行BWP3，在SUL载波上配置了2个上行BWP，分别为上行BWP4～上行BWP5，以及在下行载波上配置了4个下行BWP，分别为下行BWP0～下行BWP3，并为终端设备配置了两个上行BWP组和两个下行BWP组，两个上行BWP组为上行BWP组0和上行BWP组1，上行BWP组0中包含上行载波上的上行BWP0和上行BWP1，以及包括SUL载波上的上行BWP4，上行BWP组1中包含上行载波上的上行BWP2和上行BWP3，以及包括SUL载波上的上行BWP5，两个下行BWP组为下行BWP组0和下行BWP组1，下行BWP组0中包含下行载波上的下行BWP0和下行BWP1，下行BWP组1中包含下行载波上的下行BWP2和下行BWP3。其中，网络设备还配置了，上行载波上的上行BWP0和SUL载波上的上行BWP4为上行BWP组0中的上行待激活BWP，上行载波上的上行BWP3和SUL载波上的上行BWP5为上行BWP组1中的上行待激活BWP，下行载波上的下行BWP0为下行BWP组0中的下行待激活BWP，下行BWP3为下行BWP组1中的下行待激活BWP。那么终端设备接收网络设备的配置后，可以确定上行载波上的上行BWP0～上行BWP3、SUL载波上的上行BWP4～上行BWP5、下行载波上的下行BWP0～下行BWP3、以及上行BWP组0、上行BWP组1、下行BWP组0和下行BWP组1的信息，还可以确定上行载波上的上行BWP0、SUL载波上的上行BWP4、上行载波上的上行BWP3、SUL载波上的上行BWP5、下行载波上的下行BWP0和下行BWP3均为待激活BWP。
在前文介绍了，终端设备接收第二消息后，可以根据第二消息确定终端设备的待激活BWP，而在前文也介绍了，网络设备还可以为终端设备配置D个BWP组，那么终端设备也可以确定，终端设备的待激活BWP中的每个BWP都属于相应的BWP组，例如对于终端设备的待激活BWP中的一个上行BWP，该BWP可以是终端设备的一个上行BWP组中 的BWP，该BWP可以是第二BWP，也可以是其他的待激活BWP，这一个上行BWP组中例如包括K 5个上行BWP，K 5为正整数。再例如，对于终端设备的待激活BWP中的一个下行BWP，该BWP可以是终端设备的一个下行BWP组中的BWP，该BWP可以是第二BWP，也可以是其他的待激活BWP，这一个下行BWP组中例如包括K 6个下行BWP，K 6为正整数。其中，包括了K 5个上行BWP的上行BWP组和包括了K 6个下行BWP的下行BWP组可以均属于D个BWP组，或者，包括了K 5个上行BWP的上行BWP组和包括了K 6个下行BWP的下行BWP组也可以不是同时存在的，例如，D个BWP组中只有包括了K 5个上行BWP的上行BWP组，而没有包括了K 6个下行BWP的下行BWP组，或者，D个BWP组中只有包括了K 6个下行BWP的下行BWP组，而没有包括了K 5个上行BWP的上行BWP组。
另外，如果网络设备还为D个BWP组中的至少一个上行BWP组中的每个上行BWP组配置了至少一个上行待激活BWP，那么终端设备可以确定，对于D个BWP组中的至少一个上行BWP组中的一个上行BWP组来说，这个上行BWP组中可以包括至少一个上行待激活BWP，这至少一个上行待激活BWP包括于终端设备的待激活BWP中，也就是说，这至少一个上行待激活BWP都属于终端设备的待激活BWP，这个上行BWP组中例如包括K 7个上行BWP，K 7为正整数。如果网络设备还为D个BWP组中的至少一个下行BWP组中的每个下行BWP组配置了至少一个下行待激活BWP，那么终端设备可以确定，对于D个BWP组中的至少一个下行BWP组中的一个下行BWP组来说，这个下行BWP组中可以包括至少一个下行待激活BWP，这至少一个下行待激活BWP包括于终端设备的待激活BWP中，也就是说，这至少一个下行待激活BWP都属于终端设备的待激活BWP，这个下行BWP组中例如包括K 8个下行BWP，K 8为正整数。其中，包括了K 7个上行BWP的上行BWP组和包括了K 8个下行BWP的下行BWP组可以均属于D个BWP组，或者，包括了K 7个上行BWP的上行BWP组和包括了K 8个下行BWP的下行BWP组也可以不是同时存在的，例如，D个BWP组中只有包括了K 7个上行BWP的上行BWP组，而没有包括了K 8个下行BWP的下行BWP组，或者，D个BWP组中只有包括了K 8个下行BWP的下行BWP组，而没有包括了K 7个上行BWP的上行BWP组。
在本申请实施例中，例如网络设备可以通过第二消息或其他消息指示终端设备，为终端设备配置的全部的BWP组或其中的部分BWP组为待激活状态。其中，将一个上行BWP组设置为待激活状态，可以是指将该上行BWP组包括的全部上行BWP或部分上行BWP设置为待激活状态，将一个下行BWP组设置为待激活状态，可以是指将该下行BWP组包括的全部下行BWP或部分下行BWP设置为待激活状态。例如，网络设备还为D个BWP组中的至少一个上行BWP组中的每个上行BWP组配置了至少一个上行待激活BWP，那么这至少一个上行BWP组就可以认为被网络设备配置为了待激活状态，再例如，网络设备还为D个BWP组中的至少一个下行BWP组中的每个下行BWP组配置了至少一个下行待激活BWP，那么这至少一个下行BWP组就可以认为被网络设备配置为了待激活状态。对于终端设备来说也是同样，例如网络设备还为D个BWP组中的至少一个上行BWP组中的每个上行BWP组配置了至少一个上行待激活BWP，则终端设备可以确定D个BWP组中的至少一个上行BWP组中的每个上行BWP组中的至少一个上行待激活BWP，也就是，对于终端设备来说，也将确定了这至少一个上行BWP组为待激活状态。同理，例如网络设备还为D个BWP组中的至少一个下行BWP组中的每个下行BWP组配置了至少一 个下行待激活BWP，则终端设备可以确定D个BWP组中的至少一个下行BWP组中的每个下行BWP组中的至少一个下行待激活BWP，也就是，对于终端设备来说，也将确定了这至少一个下行BWP组为待激活状态。
可选地，如果网络设备在至少一个上行BWP组中的每个上行BWP组中配置一个上行待激活BWP，那么，网络设备可以将至少两个上行BWP组配置为待激活状态，而如果网络设备在至少一个上行BWP组中的每个上行BWP组中配置至少两个上行待激活BWP，那么，网络设备可以将至少一个上行BWP组设置为待激活状态，总之尽量保证，终端设备的待激活上行BWP为终端设备的BWP中的至少两个上行BWP。同理，如果网络设备在至少一个下行BWP组中的每个下行BWP组中配置一个下行待激活BWP，那么，网络设备可以将至少两个下行BWP组设置为待激活状态，而如果网络设备在至少一个下行BWP组中的每个下行BWP组中配置至少两个下行待激活BWP，那么，网络设备可以将至少一个下行BWP组设置为待激活状态，总之尽量保证，终端设备的待激活下行BWP为终端设备的BWP中的至少两个下行BWP。
例如网络设备在配置D个BWP组后，将全部的D个BWP组均设置为了待激活状态，则根据网络设备的指示，终端设备也确定了全部的D个BWP组均为待激活状态，且配置为待激活状态的方式为，对于D个BWP组中不包括SUL载波上的上行BWP的上行BWP组，网络设备为其中的每个上行BWP组配置一个上行待激活BWP，对于D个BWP组中包括了SUL载波上的上行BWP的上行BWP组，网络设备为其中的每个上行BWP组配置两个上行待激活BWP，这两个上行待激活BWP，包括一个设置为待激活状态的上行载波上的上行BWP和一个设置为待激活状态的SUL载波上的上行BWP。那么作为一种示例，网络设备所发送的第一消息，可以无需指示具体的新激活BWP的索引，而是可以指示BWP组的信息，例如BWP组的标识或索引，终端设备确定了BWP组，就可以默认直接切换到该BWP组的上行待激活BWP，而无需再一一通过额外信令从网络设备获取待切换的BWP，方便了终端设备的操作。其中，如果涉及到切换，那么S93同样可以理解为，终端设备切换到第二BWP，网络设备和终端设备通过第二BWP传输信号，因此，图9A所示的实施例，其对应的流程图同样可参考图9B。而终端设备切换到第二BWP后，第二BWP也就从待激活状态转为激活状态，也就是，第二BWP变成了激活BWP，因此也可以认为，是终端设备激活了第二BWP。
例如，终端设备完成初始随机接入后，网络设备为终端设备配置了4个上行BWP，分别为上行BWP0～上行BWP3，以及配置了4个下行BWP，分别为下行BWP0～下行BWP3，并为终端设备配置了两个上行BWP组和两个下行BWP组，两个上行BWP组为上行BWP组0和上行BWP组1，上行BWP组0中包含上行BWP0和上行BWP1，上行BWP组1中包含上行BWP2和上行BWP3，两个下行BWP组为下行BWP组0和下行BWP组1，下行BWP组2中包含下行BWP2和下行BWP3，下行BWP组2中包含下行BWP2和下行BWP3。其中，网络设备还配置了，上行BWP0为上行BWP组0中的上行待激活BWP，上行BWP3为上行BWP组1中的上行待激活BWP，下行BWP0为下行BWP组0中的下行待激活BWP，下行BWP3为下行BWP组1中的下行待激活BWP。例如终端设备初始工作在上行BWP组0，也就是工作在上行BWP0，那么网络设备向终端设备发送第一消息，第一消息指示新激活BWP的方式例如是指示BWP组的信息，例如第一消息指示的是上行BWP组1的索引，那么终端设备就确定待切换的目标BWP位于上行BWP组1中，则终 端设备默认切换到上行BWP组1中的上行BWP3，无需再确认BWP的索引。
作为一种特例，网络设备给终端设备配置了一个下行载波，一个上行载波和一个SUL载波，网络设备在该上行载波上为终端设备配置了一个或多个上行BWP，在SUL载波上为终端设备配置了一个或多个上行BWP，以及在下行载波上为终端设备配置了一个或多个下行BWP。网络设备还为终端设备配置BWP组，例如其中的部分或全部上行BWP组可以包括上行载波上的一个或多个上行BWP，还可以包括SUL载波上的一个或多个上行BWP。对于这样的一个上行BWP组，网络设备可以将其中的一个上行载波上的上行BWP设置为上行待激活BWP，以及将其中的一个SUL载波上的上行BWP也设置为上行待激活BWP。也就是，一个上行BWP组中的两个上行待激活BWP分别是上行载波上的上行BWP和SUL载波上的上行BWP。那么对于这样的上行BWP组，网络设备在指示终端设备切换上行BWP时，可以一并指示载波的标识，例如网络设备可以通过第一消息指示BWP组的标识以及指示待切换的目标上行待激活BWP所在的载波的标识，以指示终端设备待切换的目标上行BWP在哪一个上行载波上，从而区分上行载波上的上行BWP和SUL载波上的上行BWP。
例如网络设备在配置D个BWP组后，将全部的D个BWP组或部分的BWP组设置为了待激活状态，则在与终端设备通信的期间，网络设备可以一直保持这些BWP组处于待激活状态，当然网络设备也可以指示终端设备一直保持这些BWP组处于待激活状态。其中，BWP组保持待激活状态，可以是指该BWP组中有至少一个BWP保持待激活状态。
可选地，网络设备如果在配置BWP组后将其中的部分BWP组设置为了待激活状态，那么在通信过程中网络设备也可以更新设置为待激活状态的BWP组，且网络设备可以通过消息通知终端设备更新设置为待激活状态的BWP组，该消息例如为RRC消息、MAC CE或DCI。其中，更新可以包括，将之前未设置为待激活状态的BWP组设置为待激活状态、和/或将之前设置为待激活状态的BWP组设置为非待激活状态。关于非待激活状态，可参考第一种分组方式下的解释。
前文所述的第二种分组方式，可以适用于对称频谱系统和非对称频谱系统。对于非对称频谱系统，可以将BWP组索引相同的上行BWP组和下行BWP组配置成一个BWP组对，也就是，可以将上行BWP组和下行BWP组分别添加索引，例如上行BWP组的索引可以是1～n，下行BWP组的索引可以是1～m，m和n可以相等也可以不相等，那么其中就会有索引相同的上行BWP组和下行BWP组，就可以将索引相同的上行BWP组和下行BWP组配置成一个BWP组对。例如终端设备的下行BWP从下行BWP组1切换到下行BWP组2，则其对应的上行BWP也就需要切换到与下行BWP组2配对的上行BWP组2中的上行待激活BWP。对于对称频谱系统，上行BWP组和下行BWP组可以独立激活和待激活，例如，终端设备的下行BWP从BWP组1切换到BWP组2中的下行BWP，而终端设备的上行BWP可以切换也可以不切换，都由网络设备确定，如果终端设备的上行BWP也需要切换，那么网络设备可以一并在第一消息中指示待切换的目标上行BWP，或者指示待切换的目标上行BWP组。
可选的，对于非对称频谱系统和对称频谱系统，都可以选择将终端设备的上行BWP组和下行BWP组进行配对，当终端设备的下行BWP从下行BWP组1切换到下行BWP组2后，终端设备的上行BWP也需要切换到与下行BWP组2配对的上行BWP组2中的上行待激活BWP。
前面介绍了网络设备对配置给终端设备的BWP进行分组的两种分组方式，在本实施例中，网络设备也可以不对配置给终端设备的BWP进行分组，那么网络设备就是为终端设备配置了N个上行BWP和M个下行BWP，在这种情况下，网络设备就可以将其中的至少两个上行BWP设置为待激活BWP，或者将其中的至少两个下行BWP设置为待激活BWP，或者将其中的至少两个上行BWP设置为待激活BWP，及将其中的至少两个下行BWP设置为待激活BWP。例如网络设备可以通过第二消息将N个上行BWP和M个下行BWP通知终端设备，以及将至少两个上行待激活BWP的信息和/或至少两个下行待激活BWP的信息通知终端设备，或者网络设备也可以通过其他消息将N个上行BWP和M个下行BWP通知终端设备。终端设备接收网络设备的配置后，确定至少两个上行待激活BWP和/或至少两个下行待激活BWP为待激活状态。
可选地，无论网络设备是采用分组方式还是不采用分组方式，网络配置待激活BWP后，还可以更新待激活BWP，例如网络设备可以在与终端设备的通信过程中更新之前配置的待激活BWP，这里的更新，可以包括将原来配置的待激活BWP重新配置为非待激活BWP，和/或将原来配置为非待激活BWP重新配置为待激活BWP中。如果网络设备确定更新待激活BWP，则可以向终端设备发送消息，例如为RRC消息、MAC CE或DCI，指示更新的待激活BWP，则终端设备也可以根据网络设备的新配置重新设置。
为了便于理解上一段落所述的更新，这里简单解释一下待激活BWP组和待激活BWP之间的关系：
1、网络设备为终端设备配置了BWP组，并为BWP组配置待激活BWP，一个BWP组如果包含了待激活BWP，则该BWP组就是待激活的BWP组。
其中，网络设备在配置一个BWP组中的待激活BWP后，还可以更新该BWP组中的待激活BWP，例如将该BWP组中的待激活BWP由BWP1改变为BWP2，那么网络设备可以通过RRC消息指示终端设备，待激活BWP的更新。
2、例如，网络设备为每个BWP组配置一个第一待激活BWP，所谓的第一待激活BWP，是指在终端设备切换到该BWP组时，会直接切换到该第一待激活BWP。另外网络设备配置待激活的BWP组，如果一个BWP组被配置为待激活状态，那么该BWP组中的第一待激活BWP包括于该BWP组包括的待激活BWP中，也就是，网络设备通过将BWP组配置为待激活状态，来将该BWP组中配置的第一待激活BWP配置为待激活状态。
其中，网络设备在配置一个BWP组为待激活状态后，还可以更新被配置为待激活状态的BWP组，例如将被配置为待激活状态的BWP组由BWP组1改变为BWP组2，那么网络设备可以通过RRC消息指示终端设备，待激活BWP组的更新。
在本申请实施例中，为了使得网络设备的配置更符合终端设备的实际情况，终端设备还可以向网络设备发送能力消息，则网络设备接收来自终端设备的能力消息，能力消息中可以携带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为终端设备配置BWP，示例性地，终端设备发送能力消息和网络设备接收能力消息的过程，可以发生在前文介绍的网络设备为终端设备配置BWP的过程之前。其中，终端设备发送的能力消息可以指示终端设备能够支持的激活BWP的数量，和/或，终端设备能够支持的待激活BWP的数量，也就是，能力消息可以指示终端设备能够支持的激活BWP的数量，或指示终端设备能够支持的待激活BWP的数量，或者，指示终端设备能够支持的激活BWP的数量，以及指示终端设备能够支持的待激活BWP的数量。其中，能力消息指示终端设备能够支 持的激活BWP的数量，可以理解为，是能力消息中包括的能力信息指示终端设备能够支持的激活BWP的数量，同理，能力消息指示终端设备能够支持的待激活BWP的数量，也可以理解为，是能力消息中包括的能力信息指示终端设备能够支持的待激活BWP的数量。那么，如果能力消息要指示终端设备能够支持的激活BWP的数量，以及指示终端设备能够支持的待激活BWP的数量，也就是终端设备要发送的能力信息需要指示终端设备能够支持的激活BWP的数量，以及指示终端设备能够支持的待激活BWP的数量，可以理解为，终端设备需要发送两部分能力信息，其中一部分能力信息指示终端设备能够支持的激活BWP的数量，其中另一部分能力信息指示终端设备能够支持的待激活BWP的数量。在本实施例中，终端设备可以通过一条能力消息发送这两部分能力信息，也就是，一条能力消息可以指示终端设备能够支持的激活BWP的数量，以及指示终端设备能够支持的待激活BWP的数量，或者，终端设备也可以通过两条能力消息分别发送这两部分能力信息，也就是，一条能力消息可以指示终端设备能够支持的激活BWP的数量，另一条能力消息可以指示终端设备能够支持的待激活BWP的数量。
可选地，网络设备接收能力消息后，如果能力消息用于指示终端设备能够支持的激活BWP的数量，则网络设备就可以根据能力消息确定终端设备能够支持的激活BWP的数量，或者，如果能力消息用于指示终端设备能够支持的待激活BWP的数量，则网络设备就可以根据能力消息确定终端设备能够支持的待激活BWP的数量，或者，如果能力消息用于指示终端设备能够支持的激活BWP的数量，以及指示终端设备能够支持的待激活BWP的数量，则网络设备就可以根据终端设备的能力消息确定终端设备能够支持的激活BWP的数量，以及确定终端设备能够支持的待激活BWP的数量。
例如，终端设备可以通过随机接入过程中的消息1(msg1)、消息3(msg3)、RRC消息以及一些其他的上行消息中的一种或几种来发送终端设备的能力信息，也可以理解为，终端设备可以通过一条消息来发送终端设备的能力信息，例如终端设备发送一份能力信息，该能力信息可以适用于上行和下行，或者，终端设备也可以通过多条消息来发送终端设备的能力信息，例如终端设备可以通过不同的消息，分别发送终端设备的上行能力信息和下行能力信息。其中，消息1可以是在终端设备的初始随机接入过程中，终端设备给网络设备发送的前导序列(preamble)，消息3可以是在终端设备的初始随机接入过程中，终端设备用于确定网络设备的随机接入响应是发送给该终端设备而不是发送给其他终端设备，而向网络设备发送的第三条消息。
其中，终端设备能够支持的激活BWP的数量，是指终端设备最多可以同时在多少个BWP上传输信号或与网络设备进行通信，终端设备能够支持的待激活BWP的数量，是指终端设备最多可以同时保持多少个BWP处于待激活状态，终端设备针对这些BWP都是射频处于开启状态。其中，终端设备从一个激活BWP切换到一个待激活BWP，可以认为切换时延非常小，甚至可以认为是近似零时延，但终端设备从一个激活BWP切换到非待激活的BWP需要可度量地、相对较大地或者不可忽略的切换时延。
例如，终端设备发送的能力消息可以指示，终端设备能够支持的上行待激活BWP的数量为3，下行待激活BWP的能力为2，从而网络设备可以分别确定终端设备的上行能力和下行能力。或者，终端设备发送的能力消息可以指示，终端设备能够支持的待激活BWP的数量为2，这就表示终端设备支持的上行待激活BWP的数量和下行待激活BWP的数量都为2。
同理，例如，终端设备发送的能力消息可以指示，终端设备能够支持的上行激活BWP的数量为3，下行激活BWP的能力为2，从而网络设备可以分别确定终端设备的上行能力和下行能力。或者，终端设备发送的能力消息可以指示，终端设备能够支持的激活BWP的数量为2，这就表示终端设备支持的上行激活BWP的数量和下行激活BWP的数量都为2。
例如，终端设备只能支持同时在一个BWP上与网络设备进行通信，那么即使终端设备同时设置了多个待激活BWP，在一个时刻，也只可以在其中的一个BWP上传输数据(在传输数据时，该BWP是激活BWP，而不再是待激活BWP)，不同的待激活BWP之间可以时域复用地进行通信。或者，终端设备可以支持同时在多个BWP上与网络设备进行通信，那么终端设备可以对多个待激活BWP进行频分复用地进行通信。
可选地，如果网络设备采用的是将配置给终端设备的BWP进行分组的方式，则网络设备在接收终端设备发送的能力消息后，可以将配置给终端设备的N个上行BWP和M个下行BWP进行分组，或者，网络设备可以直接为终端设备配置一个或多个BWP组，在前文介绍了，配置给终端设备的所有的BWP组可能会同时激活，因此，配置的BWP组的数量可以小于或等于UE能够支持的待激活BWP的数量，以免同时处于待激活状态的BWP的数量超过终端设备的能力。如果终端设备支持的上行待激活BWP的数量和下行待激活BWP的数量不同，那么配置的BWP组的数量可以小于或等于终端设备支持的上行待激活BWP的数量和下行待激活BWP的数量中的较小值，例如终端设备支持的待激活BWP的数量为2，那么网络设备为该终端设备配置的BWP组的数量可以小于或等于2，具体可以取1或2。
另外，再介绍第一消息的一种可能的实现方式，在这种实现方式中，以第一消息通过DCI实现为例，该DCI可以是终端设备特定的无线网络临时标识加扰的下行控制指示。进一步地，这种实现方式适用于网络设备将配置给终端设备的BWP进行分组的方式，其中，既可以适用于前文介绍的第一种分组方式，也可以适用于前文介绍的第二种分组方式。
在本申请实施例中，例如，DCI中可以包括一个比特域，例如称为BWP指示域，BWP指示域可以用于指示新激活BWP。例如，预定义终端设备初始时在最低组号的BWP组中的上行待激活BWP和下行待激活BWP上工作，如果网络设备需要终端设备切换到其他BWP，可以通过DCI来指示终端设备切换BWP。其中，BWP指示域的长度，可以根据终端设备的一个BWP组中所包括的BWP的数量和终端设备的BWP组的总数量确定，用于确定BWP指示域的长度的这个BWP组，可以是包括的BWP的数量大于或等于终端设备的其它BWP组中所包括的BWP的数量的BWP组。其中，一个BWP组包括的BWP的数量，可以是一个BWP组包括的上行BWP的数量，那么用于确定BWP指示域的长度的这个BWP组，可以是包括的上行BWP的数量大于或等于终端设备的其它BWP组中所包括的上行BWP的数量的BWP组，或者，一个BWP组包括的BWP的数量，可以是一个BWP组包括的下行BWP的数量，那么用于确定BWP指示域的长度的这个BWP组，可以是包括的下行BWP的数量大于或等于终端设备的其它BWP组中所包括的下行BWP的数量的BWP组，或者，一个BWP组包括的BWP的数量，也可以是一个BWP组包括的上行BWP和下行BWP的总数量，那么用于确定BWP指示域的长度的这个BWP组，可以是包括的上行BWP和下行BWP的总数量大于或等于终端设备的其它BWP组中所包括的上行BWP和下行BWP的总数量的BWP组。
例如，一个BWP组包括的BWP的数量是指一个BWP组包括的上行BWP的数量，终端设备共有3个BWP组，分别为BWP组0～BWP组2，其中，BWP组0包括2个上行BWP，BWP组1包括4个上行BWP，BWP组2包括2个上行BWP，那么，就可以根据BWP组1包括的上行BWP的数量，以及终端设备的BWP组的总数量，确定BWP指示域的长度，也就是根据数值4和3确定上行BWP指示域的长度。
根据终端设备的一个BWP组中所包括的BWP的数量和终端设备的BWP组的总数量确定BWP指示域的长度，一种实现方式为如下公式：
DCI中的
Figure PCTCN2019090165-appb-000002
其中，
Figure PCTCN2019090165-appb-000003
表示向上取整，n BWP为一个BWP组包括的上行BWP或下行BWP的数量，可以是所有BWP组中的上行BWP的数量的最大值或下行BWP的数量的最大值，或者可以是预定义的值，或者，n BWP为一个BWP组包括的上行BWP和下行BWP的总数量，可以是所有BWP组中上行BWP和下行BWP的数量的最大值，n group是网络设备为终端设备配置的BWP组的总数量，上行DCI中的上行BWP指示域的长度可以根据BWP组中上行BWP的数量来确定，下行DCI中的下行BWP指示域的长度可以根据BWP组中下行BWP的数量来确定。
以前文介绍的第一种分组方式举例。例如终端设备完成初始随机接入后，网络设备为终端设备配置了4个上行BWP，为上行BWP0～上行BWP 3，以及配置了4个下行BWP，为下行BWP0～下行BWP3，网络设备还为终端设备配置了两个BWP组，BWP组0中包含上行BWP0、上行BWP1、下行BWP0和下行BWP1，BWP组1中包含上行BWP2、上行BWP3、下行BWP2和下行BWP3。其中，网络设备配置上行BWP0为BWP组0中的上行待激活BWP，下行BWP0为BWP组0中的下行待激活BWP，上行BWP3为BWP组1中的上行待激活BWP，下行BWP3为BWP组1中的下行待激活BWP。那么，作为第一消息的DCI中包括的BWP指示域的长度为2，假设终端设备初始是工作在下行BWP0上，网络设备通过该DCI指示终端设备切换BWP，那么可以通过DCI包括的BWP指示域的不同取值来指示不同内容。例如，如果BWP指示域的取值为00，表示不切换BWP，该DCI可以是用于调度的DCI，如果BWP指示域的取值为01，表示切换到BWP组0中的下行BWP1，可以认为，BWP指示域的取值01指示的是BWP组0的索引或标识，或者指示的是下行BWP1的索引或标识，如果BWP指示域的取值为10，表示切换到BWP组1中的下行BWP2，如果BWP指示域的取值为11，则为预留位(reserved)。而前文介绍了，在配置了一个BWP组中的待激活BWP后，还可以更新该组中的待激活BWP，例如对于BWP组1，其中的待激活BWP可能会由下行BWP2变为下行BWP3，那么，终端设备从BWP组0切换到BWP组1时，会直接切换到下行BWP3。
在本申请实施例中，终端设备在切换到第二BWP后，可以在第二BWP与网络设备进行通信。另外在本申请实施例中，终端设备在切换到第二BWP后，还可以继续保持第一BWP处于待激活状态，也就是，在通过第二BWP传输信号时，第一BWP还可以包括于终端设备的待激活BWP中，这样，如果终端设备下次又需要重新切换回第一BWP，也可以实现近似零时延的切换。
实际上在本实施例中，目标激活BWP除了可以是待激活BWP之外，也可以是非待激活BWP。那么进一步的，如果目标激活BWP是待激活BWP，则终端设备在切换到目标激活BWP后，还可以继续保持第一BWP处于待激活状态，而如果目标激活BWP是非待激活BWP，则终端设备在切换到目标激活BWP后，可以将第一BWP设置为非待激活状态，也就是将第一BWP去激活。因为目标激活BWP是非待激活BWP，如果终端设备在切换到目标激活BWP后还保持第一BWP处于待激活状态，可能会出现同时处于待激活状态的BWP大于终端设备能够支持的待激活BWP的数量，因此，如果目标激活BWP是非待激活BWP，则终端设备在切换到目标激活BWP后，可以将第一BWP去激活，从而使得终端设备始终按照终端设备的正常能力工作，尽量减小终端设备出故障的概率。
