这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
在本申请使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也是旨在包括多数形式，除非上下文清楚地表示其它含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本申请可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本申请范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，例如，在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
需要说明的是，本申请所涉及的信息(包括但不限于用户设备信息、用户个人信息等)、数据(包括但不限于用于分析的数据、存储的数据、展示的数据等)以及信号，均为经用户授权或者经过各方充分授权的，且相关数据的收集、使用和处理需要遵守相关国家和地区的相关法律法规和标准。
首先，对本申请所涉及的名词进行说明。
频段(band)：band是指频率范围。该频段可以具有标识，不同标识的频段对应的频率范围不同。例如，频段包括band1、band22、band72等，每个band对应一个频率范围。
频段组：该频段组包括至少两个频段，并且至少两个频段支持至少单方向的切换。并且，该频段组包括至少一个频段子组，每个频段子组包括至少两个频段，该频段子组内包括的至少两个频段支持至少单方向的切换。
频段切换：终端支持至少两个上行天线，并且支持至少一个频段，每个上行天线能够指向一个频段，而一个频段最多被两个上行天线指向。其中指向是指终端可以通过上行天线向被指向的频段发送上行数据。而频段切换是指终端使用的一个上行天线由指向一个波段切换为另一个波段。
其中，单方向的切换是指终端可以由第一个频段切换为第二个频段，而无法由第二个频段切换为第一个频段。
其次，对本申请的应用场景进行说明：
图1示出了本申请一个示例性实施例提供的通信系统的框图，该通信系统可以包括：终端10和网络设备20。
终端10的数量通常为多个，每一个网络设备20所管理的小区内可以分布一个或多个终端10。终端10可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)、移动台(Mobile Station，MS)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端。
网络设备20是一种部署在接入网中用以为终端10提供无线通信功能的装置。为方便描述，本申请实施例中，上述为终端10提供无线通信功能的装置统称为网络设备。网络设备20与终端10之间可以通过空口建立连接，从而通过该连接进行通信，包括信令和数据的交互。网络设备20的数量可以有多个，两个邻近的网络设备20之间也可以通过有线或者无线的方式进行通信。终端10可以在不同的网络设备20之间进行波束报告发送，也即与不同的网络设备20建立连接。
该网络设备20可以包括各种形式的宏基站、微基站、中继站、接入点等等。在采用不同的无线接入技术的系统中，具备网络设备功能的设备的名称可能会 有所不同，例如在5G NR(New Radio，新空口)系统中，称为gNodeB或者gNB。随着通信技术的演进，“网络设备”这一名称可能会变化。
本申请实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本申请实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
图2示出了本申请一个示例性实施例提供的频段配置方法的流程图，示例性的可以应用于如图1所示的终端和网络设备中，该方法包括以下内容中的至少部分内容：
步骤201：网络设备向终端发送频段配置信令，频段配置信令用于指示至少一个频段组，频段组包括至少两个频段，且频段组内至少两个频段支持至少单方向的切换。
步骤202：终端接收网络设备发送的频段配置信令。
在本申请实施例中，终端会获知自身支持的至少一个频段，并且网络设备还会为终端配置频段组，以便于终端可以基于频段组中包括的至少一个频段进行频段切换。
其中，单方向的切换是指终端支持由第一个频段切换为第二个频段，而无法由第二个频段切换为第一个频段。至少支持单方向的切换是指终端至少支持由第一个频段切换为第二个频段，而无法由第二个频段切换为第一个频段。该终端还可以支持至少两个频段的相互切换。
该频段配置指令用于指示至少一个频段组，且每个频段组包括至少两个频段，并且频段组内至少两个频段支持至少单方向的切换，也就是说网络设备可以通过向终端发送频段配置信令，以便于通过该频段配置信令为终端配置频段组，并且终端接收到该频段配置信令后，即可确定网络设备配置的至少一个频段组。
在一些实施例中，该频段组包括至少一个频段子组，并且每个频段子组包括至少两个频段，每个频段子组包括的至少两个频段支持至少单方向的切换。
例如，一个频段组包括一个频段子组，该频段子组包括2个频段，则说明终端支持2个频段支持至少单方向的切换。或者，一个频段组包括3个频段子组，每个频段子组包括2个频段，则每个频段子组包括的2个频段支持至少单方向的切换。
在一些实施例中，该频段配置信令的形式包括以下至少之一：RRC(Radio Resource Control，无线资源控制)信令、MAC CE(Media Access Control Control Element，媒体访问控制控制单元)、DCI(Downlink Control Information，下行控制信息)信令。
也就是说频段配置信令的形式为RRC信令，或者该频段配置信令的形式为MAC CE，或者该频段配置信令的形式为DCI信令。
本申请提供了一种基于对频段分组以便于区分频段是否可以切换的方案，根据每个频段组是否生效即可进行频段切换，实现了终端的动态切换，降低了终端进行频段切换的能耗。
图2所示实施例对网络设备可以通过频段配置信令为终端配置至少一个频段组进行说明。下面对如何通过该频段配置信令配置频段组生效继续进行说明。
第一种：频段配置信令包括第一数量的比特，至少一个频段组中的每个频段子组对应频段配置信令中的一个比特，每个频段子组对应的比特用于指示频段子组是否生效，频段子组包含至少两个频段。
其中，该第一数量由通信协议约定，或者由网络设备设置，本申请实施例不做限定。例如，该第一数量为4、6或者其他数值。
在本申请实施例中，网络设备通过在频段配置信令中设置第一数量的比特，通过第一数量的比特中的每个比特来指示频段组中包括的频段子组是否生效。也就是说，频段配置信令包括的第一数量的比特中的一个比特对应一个频段子组，并且该比特指示对应的一个频段子组是否生效。
例如，网络设备为终端配置一个频段组，该频段组包括3个频段子组，分别为频段子组1、频段子组2和频段子组3，频段子组1包括频段1和频段2，频段子组2包括频段1和频段3，频段子组3包括频段2和频段3。且频段配置信令通过3个比特xxx指示3个频段子组是否生效，3个比特与3个频段子组一一对应。其中第一个x对应频段子组1，第二个x对应频段子组2，第三个x对应频段子组3。
可选地，本申请中第一数量的比特采用bitmap(比特位图)的方式表示。该bitmap包括第一数量的比特。
在一些实施例中，若频段子组对应的比特为0，说明该频段子组不生效，而若该频段子组对应的比特为1，说明该频段子组生效。或者，若频段子组对应的 比特为0，说明该频段子组生效，而若该频段子组对应的比特为1，说明该频段子组不生效。
在一些实施例中，频段配置信令包括的比特的第一数量会大于频段组包括的频段子组的第二数量，则在此情况下，终端需要确定哪些比特有效。
可选地，在频段组包括的频段子组的第二数量小于第一数量的情况下，第一数量的比特中第二数量的高位比特与频段组的频段子组一一对应。
其中，第二数量的高位比特是指第一数量的比特中的前第二数量的比特。例如，第一数量的比特为xyzmnl，且第二数量为4，则第二数量的高位比特为xyzm。
可选地，在频段组包括的频段子组的第二数量小于第一数量的情况下，第一数量的比特中第二数量的低位比特与频段组的频段子组一一对应。
其中，第二数量的低位比特是指第一数量的比特中的后第二数量的比特。例如，第一数量的比特为xyzmnl，且第二数量为4，则第二数量的高位比特为zmnl。
可选地，频段组包括的频段子组的第二数量根据终端支持的频段的数量确定。
在本申请实施例中，网络设备为终端配置的频段子组根据终端自身支持的频段确定。也就是说，网络设备是根据终端支持的频段进行分组，以得到频段子组，因此频段组包括的频段子组的第二数量根据终端支持的频段的数量确定。
在一些实施例中，终端还可以向网络设备上报自身的能力信息，该能力信息用于指示终端支持的至少一个频段。
图3示出了本申请一个示例性实施例提供的能力指示方法的流程图，示例性的可以应用于如图1所示的终端和网络设备中，该方法包括以下内容中的至少部分内容：
步骤301：终端向网络设备发送能力信息，能力信息用于指示终端支持的至少一个频段。
步骤302：网络设备接收终端发送的能力信息。
终端向网络设备发送能力信息，该能力信息用于指示终端支持的至少一个频段，则网络设备接收到该能力信息后，即可根据该能力信息确定终端支持的至少一个频段。
例如，终端可以向网络设备上报一个频段对，也就是向网络设备上报自身 支持的两个频段。或者，终端可以向网络设备上报3个频段，或者终端可以向网络设备上报4个频段。
可选地，该能力信息还包括以下至少一项：频段的数量；频段的索引和/或标识；频段组索引。
需要说明的是，本申请实施例中的终端所执行的步骤可以单独形成一个新的实施例，网络设备所执行的步骤也可以单独形成一个新的实施例。
在一些实施例中，终端支持的频段数量包括1个、2个、3个、4个或者其他数值，本申请实施例不做限定。
下面，以终端支持的频段数量为3个以及4个进行说明。
例如，若终端支持的频段数量为3个，分别为频段A、频段B和频段C，则可以构成一个频段组，该频段组包括3个频段子组，分别为频段子组1、频段子组2和频段子组3，频段子组1包括频段A和频段B，频段子组2包括频段A和频段C，频段子组3包括频段B和频段C。
可选地，频段组也可以采用表格的方式表示。例如，参见表1，终端支持频段A、频段B和频段C，并且划分为3组频段子组。
表1
| 频段A+频段B+频段C |
| 频段A+频段B，频段A+频段C，频段B+频段C |
若频段配置信令包括6比特，分别为100011，而频段子组的数量为3，则终端确定3个低位比特有效，则说明终端支持频段子组2和频段子组3。而若终端确定3个高位比特有效，则说明终端支持频段子组1。
又例如，若终端支持的频段数量为4个，分别为频段A、频段B、频段C和频段D，则可以构成一个频段组，该频段组包括4个频段子组，分别为频段子组1、频段子组2、频段子组3和频段子组4，频段子组1包括频段A和频段B，频段子组2包括频段A和频段C，频段子组3包括频段A和频段D，频段子组4包括频段B和频段C，频段子组5包括频段B和频段D，频段子组6包括频段C和频段D。
可选地，频段组也可以采用表格的方式表示。例如，参见表2，终端支持频段A、频段B和频段C，并且划分为6组频段子组。
表2
若频段配置信令包括6比特，分别为100011，而频段子组的数量为6，则终端确定所有比特均有效，说明终端支持频段A+频段B、频段B+频段D和频段C+频段D。
本申请实施例提供的方案中，网络设备通过频段配置信令中每个比特指示对应的频段子组是否生效，根据每个频段组是否生效即可进行频段切换，实现了终端的动态切换，降低了终端进行频段切换的能耗。
需要说明的是，频段组包括的频段子组的情况根据终端支持的频段的数量确定。也可以理解为，若终端支持的频段的数量为3个，则默认确定频段组包括3个频段子组，而若终端支持的频段的数量为4个，则默认确定频段组包括6个频段组。
第二种：频段配置信令包括第一数量的比特，第一数量的比特指示索引标识，索引标识与频段组具有对应关系，第一数量的比特用于通过指示的索引标识指示对应的至少一个频段组生效。
在本申请实施例中，终端存储有索引标识与频段组具有对应关系，网络设备通过向终端发送包括第一数量的比特的频段配置信令，即可指示索引标识，终端根据第一数量的比特的索引标识确定对应的频段组生效。
在一些实施例中，该频段组包括至少一个频段子组，在终端确定指示的频段组生效的情况下，确定该频段组包括的至少一个频段子组生效。
在一些实施例中，终端存储有多个对应关系，每个对应关系与终端支持的频段的数量对应，也就是说，终端在接收到频段配置信令后，先会根据自身支持的频段的数量确定对应的索引标识与频段组的对应关系，再根据频段配置信令指示的索引标识以及确定的对应关系确定对应的频段组。
可选地，多个对应关系分别存储在不同的表格中。终端根据自身支持的频段数量即可确定对应的对应关系所在的表格。
例如，终端支持的频段数量包括1个、2个、3个、4个或其他数量。下面以终端支持的频段数量为3个或4个进行说明。
例如，若终端支持3个频段，分别为频段A、频段B和频段C，则索引标识与频段组的对应关系如表3所示。

| 2 | 频段A+频段B，频段B+频段C |
| 3 | 频段A+频段C，频段B+频段C |
| 4 | 频段A+频段B |
| 5 | 频段A+频段C |
| 6 | 频段B+频段C |
| 7 | - |
例如，若终端支持4个频段，分别为频段A、频段B、频段C和频段D，则索引标识与频段组的对应关系如表4所示。

| 索引标识 | 频段组 |
| 0 | 频段A+频段B+频段C+频段D |
| 1 | 频段A+频段B+频段C |
| 2 | 频段A+频段B+频段D |
| 3 | 频段A+频段C+频段D |
| 4 | 频段B+频段C+频段D |

| 12 | 频段A+频段C，频段B+频段D |
| 13 | 频段A+频段D，频段B+频段C |
| 14 | - |
| 15 | - |
在一些实施例中，频段配置信令包括的比特的第一数量会大于终端支持的 频段的第三数量，则在此情况下，终端需要确定哪些比特有效。
可选地，在终端支持的频段的第三数量小于第一数量的情况下，第一数量的比特中第三数量的高位比特指示索引标识。
其中，第三数量的高位比特是指第一数量的比特中的前第二数量的比特。例如，第一数量的比特为xyzmnl，且第三数量为4，则第三数量的高位比特为xyzm。
