Abstract

本申请实施例提供了一种无线通信方法、终端设备和网络设备。所述方法包括：向网络设备上报辅助信息；其中，所述辅助信息包括第一指示信息和第二指示信息，所述第一指示信息用于指示终端设备支持的波束管理模式包括公共的波束管理CBM模式，所述第二指示信息用于确定所述CBM模式对应的第一频率范围。本申请提供的无线通信方法能够提升终端设备的性能。

Description

无线通信方法、终端设备和网络设备 技术领域
本申请实施例涉及通信领域，并且更具体地，涉及无线通信方法、终端设备和网络设备。
背景技术
终端设备的波束管理模式上分为公共的波束管理(Common Beam Management，CBM)模式和独立的波束管理(Independent Beam Management，IBM)模式。CBM模式指终端设备只有一组发射/接收天线单元，即同一时刻只能产生一个波束。IBM模式指终端设备有两组(或多组)发射/接收天线单元，即同一时刻能产生两个(或多个)独立波束。
通常情况下，IBM模式具有更高的灵活性，可以工作在不同的网络设备部署场景下，而CBM模式在网络中的应用场景比较受限。但是，从终端设备实现角度看，由于IBM模式需要具备多个发射/接收天线单元，其实现复杂度、成本及耗电都比CBM模式要高。因此，在实际网络中，终端设备大多从复杂度、成本、耗电以及灵活度等方面进行考量，可以选择不同的波束管理模式。此外，终端设备可以通过辅助信息的方式，向网络设备上报终端设备支持的波束管理模式包括CBM模式和/或IBM模式，进而辅助网络设备基于终端设备支持的波束管理模式，针对调度的频段组合配置终端设备使用的波束管理模式、用于调制波束方向的波束管理参考信号等参数。例如，对于支持CBM模式的终端设备，由于终端设备在同一时刻只能产生一个波束，因此，网络设备不应该调度其在不共站址场景下的多频段上同时进行工作。
但是，对于支持CBM模式的终端设备来说，如果网络设备仅针对调度的频段组合配置终端设备使用的波束管理模式为CBM模式或IBM模式，会使得终端设备的波束赋形能力不能准确与实际需求进行匹配，降低了终端设备的性能。

在5G NR系统中，引入了毫米波工作频段，通常情况下毫米波工作频率在10GHz以上。
为便于理解本申请的方案，下面对毫米波频谱的相关内容进行说明。
图2是本申请实施例提供的5G毫米波频段的示例。
如图2所示，n257、n258、n259、n260以及n261等均是毫米波频段号。其中，n257的频谱范围为26.5GHz～29.5GHz，n258的频谱范围为24.25GHz～27.5GHz，n259的频谱范围为39.5GHz～43.5GHz，n260的频谱范围为37GHz～40GHz，n261的频谱范围为27.5GHz～28.35GHz。
由于电磁波在毫米波频段的空间传播损耗非常大，导致电磁波信号的覆盖范围受限。为了克服大的空间损耗，终端在毫米波频段一般会采用由多个天线阵子组成的天线阵来形成窄波束发射和接收信号，这些窄波束相应具有比较强的指向性。图3是本申请实施例提供的5G毫米波终端基于波束通信方式的示例。如图3所示，基站和终端之间可以通过指向性比较强的窄波束进行通信，例如，进行上行通信和/或下行通信。
在一些实施例中，终端设备可以工作在多个频段上，当终端同时在多个频段(如频段(Band)A和频段(Band)B)工作时，终端需要在多个频段同时进行波束赋形来与基站通信。从终端实现来看，有两种情况：一种情况是：终端设备只有一组发射/接收天线单元，此时，同一时刻只能采用一套波束赋形因子对频段进行赋形，也即只能按照一个频段对应的波束赋形因子对这一个频段进行波束赋形，另外一个频段按照相同的波束赋形因子进行赋形并产生波束；通常这种情况下，这种终端可称为支持公共的波束管理(Common Beam Management，CBM)模式的终端设备、具备CBM能力的终端设备或CBM能力终端。另外一种情况是：终端设备可以有两组(或多组)发射/接收天线单元，同一时刻能针对两个频段分别采用各自的波束赋形因子进行波束赋形，产生两个(或多个)独立波束；通常这种情况下，这种终端设备可称为支持独立的波束管理能力(Independent Beam Management，IBM)模式的终端设备、具备IBM能力的终端设备或IBM能力终端。
简言之，终端设备的波束管理模式上分为CBM模式和IBM模式。CBM模式指终端设备只有一组发射/接收天线单元，即同一时刻只能产生一个波束。IBM模式指终端设备有两组(或多组)发射/接收天线单元，即同一时刻能产生两个(或多个)独立波束。
图4是本申请实施例提供的支持CBM模式的终端设备的示例。
如图4所示，支持CBM模式的终端设备只有一组发射/接收天线单元，即存在一组发射/接收天线单元对应的移相器和天线阵，即频段A和频段B均可通过这一组发射/接收天线单元进行波束赋形并与基站通信，也即是说，在同一时刻终端设备只能采用一个频段对应的波束赋形参数对频段A和频段B进行波束赋形。
图5是本申请实施例提供的支持IBM模式的终端设备的示例。
如图5所示，支持IBM模式的终端设备有两组发射/接收天线单元，即每一组发射/接收天线单元对应有自己的移相器和天线阵；即频段A和频段B通过各自的一组发射/接收天线单元进行波束赋形并与基站通信；也即是说，在同一时刻下，所述终端设备能够针对频段A采用频段A的波束赋形因子进行波束赋形，并针对频段B采用频段B的波束赋形因子进行波束赋形，最终产生两个(或多个)独立波束。
针对支持CBM模式的终端设备，由于不同频段共享同一组发射/接收天线单元导致同一时刻只能按照一个频段进行波束赋形，也即意味着终端设备在同一时刻只能将一个频段的波束准确指向一个方向，因此，在多数情况下同时工作在频段A和频段B下的支持CBM模式的终端设备只能处于共站址场景的小区下，其中共站址场景也可称为多频段共波束场景。图6是本申请实施例提供的共站址场景的示例。如图6所示，在同一时刻下，频段A和频段B可以通过一个公共的波束分别与基站1和基站2进行通信。
针对支持IBM模式的终端设备，由于同一时刻可以产生两个或多个独立波束，也即意味着终端设备在同一时刻可以将波束指向不同方向，因此，同时工作在频段A和频段B下的支持IBM模式的终端设备可处于不共站址场景的小区下，不共站址场景也可称为多频段独立波束场景。图7是本申请实施例提供的不共站址场景的示例。如图7所示，在同一时刻下，频段A和频段B通过各自独立的波束分别与基站1和基站2进行通信。
通常情况下，IBM模式具有更高的灵活性，可以工作在不同的网络设备部署场景下，而CBM模式在网络中的应用场景比较受限。但是，从终端设备实现角度看，由于IBM模式需要具备多个发射/接收天线单元，其实现复杂度、成本及耗电都比CBM模式要高。因此，在实际网络中，终端设备大多从复杂度、成本、耗电以及灵活度等方面进行考量，可以选择不同的波束管理模式。此外，终端设备可以通过辅助信息的方式，向网络设备上报终端设备支持的波束管理模式包括CBM模式和/或IBM模式，进而辅助网络设备基于终端设备支持的波束管理模式，针对调度的频段组合配置终端设备使用的波束管理模式、用于调制波束方向的波束管理参考信号等参数。例如，对于支持CBM模式的终端设备，由于终端设备在同一时刻只能产生一个波束，因此，网络设备不应该调度其在不共站址场景下的多频段上同时进行工作。
但是，对于支持CBM模式的终端设备来说，如果网络设备仅针对调度的频段组合配置终端设备使用的波束管理模式为CBM模式或IBM模式，会使得终端设备的波束赋形能力不能准确与实际需求进行匹配，降低了终端设备的性能。基于此，本申请实施例提供了一种无线通信方法、终端设备和网络设备，能够提升终端设备的性能。
图8是本申请实施例提供的无线通信方法200的示意性流程图，所述无线通信方法200可以由终端设备和网络设备交互执行。图8中所示的终端设备可以是如图1所示的终端设备，图8中所示的网络设备可以是如图1所示的接入网设备。
如图8所示，所述方法200可包括：
S210，终端设备向网络设备上报辅助信息；
其中，所述辅助信息包括第一指示信息和第二指示信息，所述第一指示信息用于指示终端设备支持的波束管理模式包括公共的波束管理CBM模式，所述第二指示信息用于确定所述CBM模式对应的第一频率范围。
示例性地，网络设备收到所述终端设备上报的第一频率范围后，可以基于所述第一频率范围配置多个载波下的波束管理模式或多个频段下的波束管理模式。即所述第一频率范围用于辅助网络设备配置多个载波下的波束管理模式或用于辅助网络设备配置多个频段下的波束管理模式，或者说，所述第一频率范围可以用于网络设备调度终端设备使用的波束管理模式。具体地，网络设备可基于所述第一频率范围确定为终端设备配置的多个载波所在的频率范围或多个频段所在的频率范围是否位于所述第一频率范围内，若网络设备为所述终端设备配置的多个载波所在的频率范围或多个频段所在的频率范围位于所述第一频率范围内，则可以针对所述多个载波或所述多个频段将所述终端设备的波束管理模式配置为所述CBM模式，否则，可以可以针对所述多个载波或所述多个频段将所述终端设备的波束管理模式配置为IBM模式。
本实施例中，针对CBM模式引入了其对应的第一频率范围，基于此，终端设备向网络设备上报用于指示终端设备支持的波束管理模式包括CBM模式的第一指示信息时，还向网络设备上报用于确定所述CBM模式对应的第一频率范围的第二指示信息，有利于网络设备基于所述第二指示信息确定的所述第一频率范围配置所述终端设备使用的波束管理模式是否为CBM模式，使得终端设备的波束赋形能力能够准确的与实际需求进行匹配，提升了终端设备的波束赋形能力的利用率，进而提升了终端设备的性能。
示例性地，所述第二指示信息用于确定所述CBM模式对应的一个或多个所述第一频率范围。
当然，在其他可替代实施例中，所述第一指示信息还可以用于指示所述终端设备支持的波束管理模式包括IBM模式。例如，所述第一指示信息用于指示所述终端设备支持的波束管理模式包括所述CBM模式和所述IBM模式。
需要说明的是，在NR系统中的毫米波频段，通常终端设备采用波束赋形来克服大的传播损耗，改善上下行覆盖能力。当多个频段同时工作时(如采用载波聚合)，终端设备在这多个频段上的波束赋形能力就分为支持CBM模式、支持IBM模式及同时支持CBM模式和IBM能力模式三种情况。网络设备为了准确的配置终端设备的多频段同时工作，需要知道终端设备对应的波束赋形能力信息，网络设备根据终端设备对应的波束赋形能力信息配置终端设备的多频段工作。
由前面所述，CBM模式相比IBM模式在波束赋形能力上有所受限，但其好处是能够有更低的功耗表现，因此在网络条件允许的情况下终端设备可能更加倾向于采用CBM模式进行通信。CBM模式存在的问题是其能支持的频率范围比较有限。
考虑到毫米波天线在进行波束赋形时通常可以在谐振中心频点F0处达到最优的赋形增益，而在偏离这个谐振中心频点时其赋形增益逐渐降低，也即是说，毫米波天线阵列可以工作在一定的频谱宽度内。图9是本申请实施例提供的第一频率范围的示例。如图9所示，FS_CBM用于表示第一频率范围，毫米波天线阵列工作的频率范围的宽度超过所述第一频率范围的宽度时，终端设备的赋形增益将会下降，相应的，其峰值功率及覆盖都将受到影响。基于此，本申请针对CBM模式引入了其对应的第一频率范围，用于辅助网络设备配置多个载波下的波束管理模式或用于辅助网络设备配置多个频段下的波束管理模式，或者说，所述第一频率范围可以用于网络设备调度终端设备使用的波束管理模式。
在一些实施例中，所述第二指示信息用于指示以下中的至少一项：所述CBM模式支持的频率间隔、所述CBM模式支持的频率间隔范围、所述CBM模式支持的频率间隔范围对应的等级。所述CBM支持的频率间隔的范围对应的等级也可以简称为CBM频率间隔范围等级(Frequency separation range class for CBM)。
换言之，所述第二指示信息用于指示用于确定所述第一频率范围的信息，所述用于确定所述第一频率范围的信息包括但不限于：所述CBM模式支持的频率间隔、所述CBM模式支持的频率间隔范围、所述CBM模式支持的频率间隔范围对应的等级。
示例性地，所述CBM模式支持的频率间隔可以是在多个候选频率间隔中选择的频率间隔。例如，所述多个候选频率间隔包括但不限于：1GHz，2GHz，3GHz，4GHz，5GHz。当然，在其他可替代实施例中，所述多个候选频率间隔也可以是其他取值或者其他具体形式的频率间隔，本申请对此不作具体限定。

示例性地，所述CBM频率间隔范围等级可以是在多个候选等级中选择的等级。例如，所述多个候选等级包括但不限于：A、B、C、D、E。当然，在其他可替代实施例中，所述多个候选等级也可以是其他取值或者其他具体形式的等级，本申请对此不作具体限定。
示例性地，所述CBM模式支持的频率间隔范围可以和所述CBM频率间隔范围等级存在对应关系。例如所述CBM支持的频率间隔范围和所述CBM频率间隔范围等级之间的对应关系可以如表1所示。
表1
CBM频率间隔范围等级 CBM支持的频率间隔范围
A 0＜F s≤1GHz
B 1GHz＜F s≤2GHz
C 2GHz＜F s≤3GHz
D 3GHz＜F s≤4GHz
E 4GHz＜F s≤5GHz
如表1所示，CBM模式支持的不同频率间隔范围可以对应不同的CBM频率间隔范围等级。例如CBM频率间隔范围等级为A时，CBM支持的频率间隔范围为0＜Fs≤1GHz；CBM频率间隔范围等级为B时，CBM支持的频率间隔范围为1GHz＜F s≤2GHz；其中，F s表示CBM支持的频率间隔。
当然，表1仅为对本申请的示例，也不应理解为对本申请的限制。例如，在表1中，CBM支持的频率间隔的范围的宽度为1GHz，在其他可替代实施例中，可以CBM支持的频率间隔的范围的宽度为 其他数值。
需要说明的是，所述第二指示信息可以用于确定所述CBM模式对应的一个或多个所述第一频率范围。
示例性地，所述第二指示信息用于指示以下中的至少一项：所述CBM模式支持的一个或多个频率间隔、所述CBM模式支持的一个或多个频率间隔范围、所述CBM模式支持的一个或多个频率间隔范围中的每一个频率间隔范围对应的等级。
在一些实施例中，所述辅助信息还包括第三指示信息，所述第三指示信息用于指示所述第一频率范围对应的赋形增益损失。换言之，终端设备向网络设备上报用于确定所述第一频率范围的信息和所述第一频率范围对应的赋形增益损失。
本实施例中，通过所述第二指示信息和所述第三指示信息，网络设备可以很明确的知道终端设备工作在所述CBM模式下的第一频率范围内时，所述终端设备的赋形增益损失，进而，网络设备可以配置终端设备在所述CBM模式下工作时，可以使用载波组合或可以使用的频段组合，使得终端设备的波束赋形能力能够准确的与实际需求进行匹配，提升了终端设备的波束赋形能力的利用率，进而提升了终端设备的性能。
示例性地，所述第一频率范围对应的赋形增益损失可以是在多个候选损失中选择的赋形增益损失。例如，所述多个候选损失包括但不限于：1dB，2dB，3dB，4dB。当然，在其他可替代实施例中，所述多个候选损失也可以是其他取值或者其他具体形式的损失值，本申请对此不作具体限定。

以所述第二指示信息用于指示所述CBM模式支持的一个或多个CBM频率间隔范围等级为例，结合表1来说，所述第二指示信息用于确定终端设备仅上报CBM频率间隔等级A以及所述CBM频率间隔等级A对应的赋形增益损失1dB；或终端设备仅上报CBM频率间隔等级B以及所述CBM频率间隔等级A对应的赋形增益损失2dB；或终端设备在上报CBM频率间隔等级A以及所述CBM频率间隔等级A对应的赋形增益损失1dB的同时，上报CBM频率间隔等级B以及所述CBM频率间隔等级A对应的赋形增益损失2dB。
当然，在其他可替代实施例中，所述辅助信息不包括所述第三指示信息时，也可以认为所述第一频率范围对应的赋形增益损失为0或者为默认值，本申请对此不作具体限定。在其他可替代实施例中，所述第二指示信息和所述第三指示信息可以联合指示，也即是说，所述第二指示信息和所述第三指示信息可以作为一个指示信息，用于联合指示用于确定所述第一频率范围的信息和所述第一频率范围对应的赋形增益损失。
在一些实施例中，所述第一频率范围为赋形增益损失小于或等于第一门限值的最大频率范围。可选的，所述第一门限值由网络设备配置，或所述第一门限值由协议约定。
换言之，所述第一频率范围对应的最大赋形增益损失为所述第一门限值。
本实施例中，通过所述第二指示信息，网络设备可以很明确的知道终端设备工作在所述CBM模式下的第一频率范围内时，所述终端设备的赋形增益损失，进而，网络设备可以配置终端设备在所述CBM模式下工作时，可以使用载波组合或可以使用的频段组合，使得终端设备的波束赋形能力能够准确的与实际需求进行匹配，提升了终端设备的波束赋形能力的利用率，进而提升了终端设备的性能。此外，避免了终端设备上报所述第一频率范围对应的赋形增益损失，能够降低所述终端设备的信令开销以及所述终端设备的功耗。
需要说明的是，在本申请实施例中，所述"协议"可以指通信领域的标准协议，例如可以包括LTE协议、NR协议以及应用于未来的通信系统中的相关协议，本申请对此不做具体限定。所述第一门限值由协议约定时，其可以通过在设备(例如，包括终端设备和网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现，本申请对于其具体的实现方式不做限定。
还需要说明的是，所述第一门限值可以为所述CBM模式下的赋形增益损失的最大取值。
示例性地，所述第一门限值可以为所述CBM模式允许的赋形增益损失的最大取值。
示例性地，所述第一频率范围为赋形增益损失小于或等于所述CBM模式下的赋形增益损失的最大取值的最大频率范围。所述最大取值可以由网络设备配置，或所述最大取值可以由协议约定。

示例性地，所述辅助信息的上报可以是区分上行传输和下行传输的上报，也可以是不区分上行传输和下行传输的上报，即所述辅助信息可以同时适用于上行传输和下行传输。
在一些实施例中，所述方法200还可包括：
接收所述网络设备发送的无线资源控制(Radio Resource Control，RRC)配置信息；
其中，所述RRC配置信息用于配置以下中的至少一项：所述终端设备使用的波束管理模式、与所述终端设备使用的波束管理模式对应的多个频段、与所述终端设备使用的波束管理模式多个载波、所述多个载波对应的波束管理参考信号；
所述多个载波包括配置在所述多个频段中的每一个频段上的载波。
示例性地，所述终端设备使用的波束管理模式可以是所述CBM模式，也可以是所述IBM模式。
示例性地，所述终端设备使用的波束管理模式可以是网络设备基于所述第一频谱范围确定的模式。
示例性地，所述多个频段或所述多个频段可以是网络设备基于所述第一频谱范围确定的。
在一些实施例中，若所述终端设备使用的波束管理模式为所述CBM模式，则所述多个频段所在的频率范围和/或所述多个载波所在的频率范围位于所述第一频率范围内。
示例性地，若所述多个频段所在的频率范围和/或所述多个载波所在的频率范围位于所述第一频率范围内，则网络设备可以配置所述终端设备使用所述CBM模式，否则，网络设备可以配置所述终端设备使用所述IBM模式。
图10是本申请实施例提供的多个频段和第一频率范围的示例。
如图10所示，对于所述CBM模式，需要将所述CBM支持的频段A和频段B所在的频率范围限制在第一频率范围内，或者说，所述CBM模式支持的频段组合需要限制在所述第一频率范围内，而对于所述IBM模式，由于其通常会采用独立的收发链路来支持多个频段，因此其能够支持的频段组合的最大频率范围通常是没有限制的，即不会在频率范围上对所述IBM模式支持的频段A和频段B进行限制。
在一些实施例中，若所述终端设备使用的波束管理模式为所述CBM模式，则所述多个载波中的部分载波存在对应的波束管理参考信号；若所述终端设备使用的波束管理模式为独立的波束管理IBM模式时，则所述多个载波中的每一个载波存在对应的波束管理参考信号。
示例性地，所述CBM模式与所述IBM模式为两种不同的终端设备波束管理模式，其中，对于所述CBM模式，网络设备可以只在部分载波上为终端设备配置波束管理参考信号，即终端设备依据在部分载波上配置的波束管理参考信号完成所有载波的收发波束管理，例如，完成对所有载波的收发波束的波束方向的调制。所述IBM模式需要网络设备在各载波上为终端设备配置独立的波束管理参考信号，即终端设备在各载波上依据相应的波束管理参考信号进行收发波束管理，例如，完成对各个载波的收发波束的波束方向的调制。
需要说明的是，上述方法200可以用于解决终端设备支持CBM模式时，终端设备上报的辅助信息不够充分的问题，通过上述方法200，在终端设备支持CBM模式时，网络设备可以基于所述CBM对应的第一频率范围和/或所述第一频率范围对应的赋形增益损失(例如峰值功率损失和/或覆盖损失和/或接收灵敏度损失)对终端设备进行相应的配置，例如，配置终端设备使用的波束管理模式、与终端设备使用的波束管理模式对应的载波或频段等参数。由此可见，上述方法200主要针对网络设备配置终端设备使用的波束管理模式为所述CBM模式时细化了终端设备上报的辅助信息。
当然，对于同时支持所述CBM模式和所述IBM模式的终端设备，其可以从复杂度、成本、耗电以及灵活度等方面进行考量，合适的波束管理模式。此外，由于信号的发射对终端设备的功耗及散热等的影响会更大，而信号的接收则影响很小，因此，网络设备可以针对上行传输和/或下行传输，分别配置终端设备的波束管理模式，例如，可以针对上行传输，将所述终端设备使用的波束管理模式配置为所述CBM模式或所述IBM模式；再如，可以针对下行传输，将所述终端设备使用的波束管理模式配置为所述CBM模式或所述IBM模式。
此外，对于同时支持所述CBM模式和所述IBM模式的终端设备，所述终端设备通过辅助信息将所述CBM模式对应的第一频率范围上报给网络设备后，网络设备可以判断在多大的频率范围内终端设备支持所述CBM模式。进一步的，网络设备可以决定针对某个频段组合将所述终端设备使用的波束管理模式配置为所述CBM模式或所述IBM模式。然而，这种方式下的终端设备失去了对所述CBM模式或所述IBM模式的建议权，实际上，终端设备由于受到功耗、电量、发热等因素的影响，其在某些场景下依然希望能够工作于某种波束管理模式下。
有鉴于此，本申请基于上文涉及的第一频率范围还提供了一种无线通信方法以实现对终端设备使用的波束管理模式进行切换。
图11是本申请实施例提供的无线通信方法310的示意性流程图，所述方法310可由终端设备执行，例如图1所示的终端设备。
如图11所示，所述方法310可包括：
S311，将所述终端设备使用的波束管理模式由第一波束管理模式切换为第二波束管理模式；
其中，所述第二波束管理模式为公共的波束管理CBM模式或独立的波束管理IBM模式，所述CBM模式对应第一频率范围。
本实施例中，针对CBM模式引入了其对应的第一频率范围，有利于终端设备基于所述第一频率范围确定所述终端设备使用的波束管理模式是否为CBM模式，或者，有利于网络设备基于所述第一频率范围配置所述终端设备使用的波束管理模式是否为CBM模式，不仅使得终端设备的波束赋形能力能够准确的与实际需求进行匹配，提升了终端设备的波束赋形能力的利用率，进而提升了终端设备的性能，还能够实现CBM模式的切换。
需要说明的是，所述第一频率范围的实现方式可以参考方法200中的描述，为避免重复，此处不再赘述。
示例性地，由于信号的发射对终端设备的功耗及散热等的影响会更大，而信号的接收则影响很小。因此，终端设备可以针对上行传输和/或下行传输，分别切换终端设备使用的波束管理模式。例如，可以针对上行传输，将所述终端设备使用的波束管理模式由第一波束管理模式切换为第二波束管理模式；再如，可以针对下行传输，将所述终端设备使用的波束管理模式由第一波束管理模式切换为第二波束管理模式。
需要说明的是，本申请提供的方案不仅可以用于实现所述CBM模式与所述IBM模式之间的切换，还可用于实现所述CBM模式和所述CBM模式之间的切换，本申请对此不作具体限定。
示例性地，所述第一波束管理模式可以包括CBM模式或所述IBM模式。
示例性地，所述第一波束管理模式和所述第二波束管理模式可以都是所述CBM模式，所述第一波束管理模式对应的频率范围不同于所述第二波束管理模式对应的频率范围。
示例性地，所述第一波束管理模式可以为所述IBM模式，所述第二波束管理模式可以为所述CBM模式，所述CBM模式对应第一频率范围。
示例性地，所述第一波束管理模式可以为所述CBM模式，所述第二波束管理模式可以为所述IBM模式，所述CBM模式对应第一频率范围。
在一些实施例中，所述S311可包括：
向网络设备发送切换请求，所述切换请求用于请求切换所述终端设备的波束管理模式；
接收所述网络设备发送的无线资源控制RRC重配置信息；
其中，所述RRC重配置信息用于配置以下中的至少一项：所述第二波束管理模式、所述第二波束管理模式对应的多个频段、所述第二波束管理模式对应的多个载波、所述多个载波对应的波束管理参考信号；所述多个载波包括配置在所述多个频段中的每一个频段上的载波。
示例性地，所述终端设备在向所述网络设备发送所述切换请求之前，还可以向所述网络设备发送用于指示所述终端设备支持的波束管理模式的信息，例如，向所述网络设备发送用于指示所述终端设备同时支持所述CBM模式和所述IBM模式的信息。例如所述终端设备可以采用方法200中涉及的方法，向所述网络设备发送辅助信息，所述辅助信息包括第一指示信息和第二指示信息，所述第一指示信息用于指示所述终端设备同时支持所述CBM模式和所述IBM模式，所述第二指示信息用于确定所述CBM 对应的第一频率范围。一方面，终端设备通过辅助信息将所述CBM模式对应的第一频率范围上报给网络设备后，网络设备可以判断在多大的频率范围内终端设备支持所述CBM模式；进一步的，网络设备可以决定针对某个频段组合是否可以将所述终端设备使用的波束管理模式切换为所述CBM模式。另一方面，网络设备可以基于所述第一指示信息确定终端设备是否支持所述IBM模式，进一步的，网络设备可以决定针对某个频段组合是否可以将所述终端设备使用的波束管理模式切换为所述IBM模式。由此，能够实现对终端设备使用的波束管理模式进行切换。
本实施例中，网络设备收到终端设备发送的切换请求后，可以通过RRC重配置信息对终端设备使用的波束管理模式以及相关参数进行切换，例如，对终端设备使用的波束管理模式、与终端设备使用的波束管理模式对应的载波或频段等参数进行切换。
在一些实施例中，所述切换请求包括第四指示信息，所述第四指示信息用于指示所述终端设备期望的波束管理模式，所述终端设备期望的波束管理模式为所述CBM模式或所述IBM模式。
