请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、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、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统 可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13 可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
本公开实施例涉及的执行主体包括但不限于：采用蜂窝移动通信技术进行通信的终端等用户设备UE，以及基站等。
本公开实施例的一种应用场景为，UE为了实现波束成型，需要多个天线单元，如下图2所示，四个天线单元形成的宽度较宽的波束。关闭部分天线单元，如图3所述，关闭两个天线单元后可以得到宽度较宽的波束。宽度较窄的波束的指向性较好，能量集中，可以适用于信道条件差，大数据量传输。
当UE用户的信道条件比较好，而且没有大量的数据需要传输时，此时宽度较窄的波束是没有必要。如果切换成宽度较宽的波束，不仅由于使用较少的天线单元会更省电，而且由于宽度变宽，移动性能会变得更好。因此能够关闭部分天线单元对终端来说是非常有益的。
UE对应波束切换的能力不同。第一种UE在波束切换后能够保证切换后的波束指向与切换前保证一致性，即波束切换前波束的峰值增益(peak gain)和切换后波束峰值增益的方向基本一致，或者小于某一个范围。第二种UE波束切换前波束的峰值增益和宽度切换后波束峰值增益的方向会超出某一范围，从而降低信号传输性能。
如图4所示，本示例性实施例提供一种信息传输方法，可以应用于无 线通信的第一通信节点中，信息传输方法可以包括：
步骤401：向第二通信节点发送指示从第一波束切换到第二波束的切换请求，其中，所述第一波束不同于第二波束。
这里，第一通信节点可以是采用蜂窝移动通信技术等无线通信技术进行通信终端等UE，第二通信节点可以是UE也可以是蜂窝移动通信中的基站等。
第一通信节点和第二通信节点均可以支持采用波束赋形产生波束进行通信。
这里，第一波束和第二波束可以是第一通信节点接收第二通信节点发送的信号的波束。第一波束和第二波束也可以是第一通信节点发送信号的波束。第一波束不同于第二波束可以是具有不同指向性或不同能量集中度的波束等。示例性的，第一波束所需的天线单元数量不同于第二波束所需的天线单元数量；或者第一波束的宽度不同于第二波束的宽度等。第一波束可以先当前采用的波束，第二波束可以是切换的目标波束。
第一波束和第二波束可以用于不同场景的通信。例如，第一波束是宽度较大的波束，第二波束是宽度较小的波束。
第一通信节点可以根据当前通信场景确定是否要进行波束切换。例如，第一通信节点和第二通信节点相对运动速度交快时，第一通信节点可以选择宽度较大的波束。
第一通信节点可以发送切换请求，指示第一通信节点从第一波束切换到第二波束。
第二通信节点接收到切换请求确定是否知识第二波束的传输，或者，配置第二波束资源等。
如此，第一通信节点通过发送切换请求实现波束的切换，一方面，第一通信节点可以选择不同的波束进行通信，不限于采用同一类波束进行通 信，提高波束选择灵活性。另一方面，第一通信节点可以选择适合当前通信场景的波束进行通信，进而提高通信效率。
在一个实施例中，所述切换请求包括波束变化指示，用于指示所述第一波束与所述第二波束的差异。
这里，第一波束与第二波束的差异可以是第一波束与第二波束指向以及宽度的差异等。
第二通信节点可以根据波束变化指示确定是否允许第一通信节点从第一波束切换到第二波束。例如，可以根据第二波束的宽度等确定是否会与其他通信节点的波束产生干扰，确定是否允许第一通信节点从第一波束切换到第二波束。
在一个实施例中，所述波束变化指示，用于指示所述第一波束的宽度大于所述第二波束的宽度，或者所述第一波束的宽度小于所述第二波束的宽度。
第一波束可以是图2所示的波束，第二波束可以是图3所示的波束；或者，第一波束可以是图3所示的波束，第二波束可以是图2所示的波束。第一波束和第二波束的宽度不同。
这里，宽度较宽的波束采用的天线单元数较少，宽度较窄大的波束采用的天线单元数较多。
宽度较宽的波束，可以使用较少数量的天线单元，从而更省电，而且由于宽度变宽，移动性能会变得更好。
宽度较宽的波束，可以使用较多数量的天线单元，指向性更强，能量更集中，抗干扰能力更强，可以适用于信道条件差的通信传输。
示例性的，第一通信节点当前波束为宽度较宽的波束，并且当前波束条件下信道条件较差，且有大量业务数据需要传输，第一通信节点可向第二通信节点申请切换到宽度较窄的波束。
另一个示例中，第一通信节点当前波束为宽度较窄的波束，第一通信节点所处信道条件较好，比如通过第二通信节点下行链路估计出路径损耗较低，或者信噪比大于某一值时，且判断传输的业务量较小时，第一通信节点可向第二通信节点申请切换到宽度较宽的波束。
在一个实施例中，所述波束变化指示，用于指示所述第一波束的宽度和所述第二波束的宽度的差异值。
波束变化指示可以指示第二波束相对第一波束的变化，例如，波束变化指示可以指示第二波束相对第一波束宽度变大或变小，以及第二波束相对第一波束宽度变化的差异值。
这里，差异值可以是具体的宽度差异值，也可以是第二波束宽度与第一波束宽度的比例关系。
示例性的，如表1所示，波束变化指示可以通过一个比特为指示第二波束相对第一波束宽度增大还是减小，通过另一个比特为指示第二波束宽度与第一波束宽度的比例关系，即宽度变化因子。
表1
Figure PCTCN2020103348-appb-000001
如此，通过波束变化指示可以显性地指示切换前后波束的差异。
在一个实施例中，所述切换请求包括：指示所述第一通信节点能力的能力信息。
第一通信节点能力可以包括：第一通信节点可切换的波束宽度，以及 从第一波束切换到第二波束在波束指向上的控制能力等。第二通信节点可以基于第一通信节点能力判断是否运行波束切换。
在一个实施例中，指示所述第一通信节点能力的所述能力信息，用于指示所述第一通信节点具有保证切换前后波束朝向一致性的能力，或者指示所述第一通信节点不具有保证切换前后波束朝向一致性的能力。
不同第一通信节点具有不同的波束切换能力。一个实施例中，第一通信节点进行波束切换后可以确保切换后的波束指向与切换前的波束指向保证一致性，波束切换前后峰值增益方向基本一致，或者波束切换前后峰值增益方向偏差小于或等于偏差阈值。如图5所示，另一个实施例中，第一通信节点进行波束切换后，波束切换前后的峰值增益方向偏差角度大于偏差阈值。
如果波束切换前后的峰值增益方向偏差大于或等于偏差阈值，即切换后第二波束峰值增益方向与第二通信节点的偏差角度较大，从而降低信号传输质量。
如此，第一通信节点通过波束扫描请求信息请求采用第二波束进行波束扫描，确定满足传输需求的一个第二波束，可以减少由于波束类型切换产生的切换前后波束峰值增益方向不一致的情况，进而提高信号传输效率。
在一个实施例中，所述切换请求包括：波束扫描请求信息，用于请求采用所述第二波束进行波束扫描的扫描资源。
第一通信节点可以在切换请求中携带波束扫描请求信息，用于向第二通信节点请求进行波束管理。这里，波束管理是指第一通信节点采用多个第二波束对第二通信节点发射的参考信号等信号进行扫描，确定信号满足预设条件的一个第二波束，将该第二波束作为第一通信节点和第二通信节点之间通信的波束。
波束扫描请求信息可以用于向第二通信节点请求进行波束扫描的扫描 资源。这里，扫描资源可以包括：扫频的时隙资源和频率资源等。
第二通信节点接收到切换请求后，如果允许进行波束切换，则可以确定用于第二波束扫描的扫描资源。
第一通信节点的能力信息可以作为一种波束扫描请求信息。例如，第一通信节点发送的能力信息指示第一通信节点进行波束切换前波束的峰值增益方向与进行波束切换后波束的峰值增益方向的偏差小于或等于偏差阈值。第二通信节点接收到波束扫描请求信息后可以确定第一通信节点需要进行第二波束的扫描。
通波束扫描可以确定出信号质量最优的第二波束用于第一通信节点和第二通信节点的通信，提高通信质量。
在一个实施例中，所述方法还包括：
接收所述第二通信节点发送的携带有指示所述扫描资源的资源信息的切换响应；
在所述扫描资源上，采用至少一个所述第二波束进行波束扫描，将扫描结果满足第一条件的所述第二波束，确定为用于所述第一通信节点和所述第二通信节点之间通信的波束。
这里，第二通信节点可以通过切换响应中携带的资源信息指示用于波束扫描的扫描资源，扫描资源可以包括：扫频的时隙资源和频率资源等。
第一通信节点接收到切换响应后，确定出扫描资源。并在扫描资源上，采用多个第二波束对第二通信节点发射的参考信号等信号进行扫描，确定扫描结果满足预设条件的一个第二波束，将该第二波束作为第一通信节点和第二通信节点之间通信的波束。这里，扫描结果，可以是采用第二波束进行扫描确定的第二通信节点发射的参考信号等信号的信号质量参数，如参考信号接收功率(RSRP，Reference Signal Receiving Power)、RSRQ、SINR等。
示例性的，第一通信节点可以采用第二波束进行扫描，确定RSRP最优的一个第二波束，将该信息传输用于第一通信节点和第二通信节点之间的通信。
如此，第一通信节点采用第二波束进行波束扫描，确定满足传输需求的一个第二波束，可以减少由于波束类型切换产生的切换前后波束峰值增益方向不一致的情况，进而提高信号传输效率。
在一个实施例中，所述方法还包括：
接收所述第二通信节点响应于所述第一通信节点切换到所述第二波束，发送的信号传输指示信息；
根据所述信号传输指示信息，确定在所述第二波束上传输信号的配置。
第二通信节点在第一通信节点完成切换波束后，还可以向第一通信节点下发根据第二波束重新调整相应的传输信号的配置，如信号传输功率配置等，这里，传输功率配置可以包括：移动性管理的测量间隔时间配置、信号发射功率配置等。
第一通信节点基于功率配置，在第二波束上进行数据通信。例如，根据功率配置所配置的测量间隔时间进行信号测量等。从而满足功率控制需求，进而节省电量。
在一个实施例中，所述向第二通信节点发送请求从第一波束切换到第二波束的切换请求，包括以下至少之一：
响应于所述第一通信节点的电量低于电量阈值，向所述第二通信节点发送所述切换请求；
响应于所述第一通信节点的位于预定位置，向所述第二通信节点发送所述切换请求；
响应于所述第一通信节点的位于所述预定位置，并且所述第一通信节点在所述预定位置采用的历史波束为所述第二波束，向所述第二通信节点 发送所述切换请求。
示例性的，第一通信节点由于省电的需要，例如电量低于电量阈值时，第一通信节点可以向第二通信节点申请从第一波束切换到第二波束。这里，第一波束的宽度小于第二波束的宽度，因此，第一波束采用的天线单元数量较多，消耗电量更多。
在另一个实施例中，第一通信节点可以根据所处位置确定需要采用的波束类型，例如，在离第二通信节点距离较近的位置，可以采用宽度较宽的波束，在离第二通信节点距离较远的位置，可以采用宽度较窄的波束，如此，可以提高信号接收效率。第一通信节点根据位置来判断是否需要向第二通信节点申请波束切换，终端位置信息可以根据GPS或者其它位置测量单元测得。
在另一个实施例中，第一通信节点可以根据在所处位置的波束类型历史使用记录确定采用的波束，例如，当第一通信节点当前波束类型与当前位的历史波束类型不相同时，可向第二通信节点申请波束切换。
在一个实施例中，所述方法还包括：
接收所述第二通信节点响应于所述请求信息发送的切换响应，其中，所述切换响应，用于指示允许切换到所述第二波束；
响应于接收到所述切换响应，在所述第二波束上与所述第二通信节点进行通信。
第二通信节点可以根据波束变化指示确定是否允许第一通信节点从第一波束切换到第二波束。例如，可以根据第二波束的宽度等确定是否会与其他通信节点的波束产生干扰，确定是否允许第一通信节点从第一波束切换到第二波束。第二通信节点也可以根据自身负载情况确定是否允许第一通信节点从第一波束切换到第二波束；例如第二通信节点的负载大于负载阈值时，不允许第一通信节点从第一波束切换到第二波束。第二通信节点 还可以根据第一通信节点的能力确定是否允许第一通信节点从第一波束切换到第二波束；例如，当第一通信节点波束管理能力较弱，即第一通信节点进行波束切换前波束的峰值增益方向与进行波束切换后波束的峰值增益方向的偏差大于或等于偏差阈值，并且第一通信节点未在切换请求中携带波束扫描请求信息时，不允许第一通信节点从第一波束切换到第二波束。
第二通信节点可以发送指示允许进行波束切换的切换响应。第一通信节点接收到切换响应后，从第一波束切换到第二波束。如果没有接收到指示允许进行波束切换的切换响应，则不进行波束切换。
如图6所示，本示例性实施例提供一种信息传输方法，可以应用于无线通信的第二通信节点中，信息传输方法可以包括：
步骤601：接收第一通信节点发送的指示从第一波束切换到第二波束的切换请求，其中，所述第一波束不同于第二波束。
这里，第一通信节点可以是采用蜂窝移动通信技术等无线通信技术进行通信终端等UE，第二通信节点可以是UE也可以是蜂窝移动通信中的基站等。
第一通信节点和第二通信节点均可以支持采用波束赋形产生波束进行通信。
这里，第一波束和第二波束可以是第一通信节点接收第二通信节点发送的信号的波束。第一波束和第二波束也可以是第一通信节点发送信号的波束。第一波束不同于第二波束可以是具有不同指向性或不同能量集中度的波束等。示例性的，第一波束所需的天线单元数量不同于第二波束所需的天线单元数量；或者第一波束的宽度不同于第二波束的宽度等。第一波束可以先当前采用的波束，第二波束可以是切换的目标波束。
第一波束和第二波束可以用于不同场景的通信。例如，第一波束是宽度较大的波束，第二波束是宽度较小的波束。
第一通信节点可以根据当前通信场景确定是否要进行波束切换。例如，第一通信节点和第二通信节点相对运动速度交快时，第一通信节点可以选择宽度较大的波束。
第一通信节点可以发送切换请求，指示第一通信节点从第一波束切换到第二波束。
第二通信节点接收到切换请求确定是否知识第二波束的传输，或者，配置第二波束资源等。
如此，第一通信节点通过发送切换请求实现波束的切换，一方面，第一通信节点可以选择不同的波束进行通信，不限于采用同一类波束进行通信，提高波束选择灵活性。另一方面，第一通信节点可以选择适合当前通信场景的波束进行通信，进而提高通信效率。
在一个实施例中，所述切换请求包括波束变化指示，用于指示所述第一波束与所述第二波束的差异。
这里，第一波束与第二波束的差异可以是第一波束与第二波束指向以及宽度的差异等。
第二通信节点可以根据波束变化指示确定是否允许第一通信节点从第一波束切换到第二波束。例如，可以根据第二波束的宽度等确定是否会与其他通信节点的波束产生干扰，确定是否允许第一通信节点从第一波束切换到第二波束。
在一个实施例中，所述波束变化指示，用于指示所述第一波束的宽度大于所述第二波束的宽度，或者所述第一波束的宽度小于所述第二波束的宽度。。
第一波束可以是图2所示的波束，第二波束可以是图3所示的波束；或者，第一波束可以是图3所示的波束，第二波束可以是图2所示的波束。第一波束和第二波束的宽度不同。
这里，宽度较宽的波束采用的天线单元数较少，宽度较窄大的波束采用的天线单元数较多。
宽度较宽的波束，可以使用较少数量的天线单元，从而更省电，而且由于宽度变宽，移动性能会变得更好。
宽度较宽的波束，可以使用较多数量的天线单元，指向性更强，能量更集中，抗干扰能力更强，可以适用于信道条件差的通信传输。
示例性的，第一通信节点当前波束为宽度较宽的波束，并且当前波束条件下信道条件较差，且有大量业务数据需要传输，第一通信节点可向第二通信节点申请切换到宽度较窄的波束。
另一个示例中，第一通信节点当前波束为宽度较窄的波束，第一通信节点所处信道条件较好，比如通过第二通信节点下行链路估计出路径损耗较低，或者信噪比大于某一值时，且判断传输的业务量较小时，第一通信节点可向第二通信节点申请切换到宽度较宽的波束。
在一个实施例中，所述波束变化指示，用于指示所述第一波束的宽度和所述第二波束的宽度的差异值。
波束变化指示可以指示第二波束相对第一波束的变化，例如，波束变化指示可以指示第二波束相对第一波束宽度变大或变小，以及第二波束相对第一波束宽度变化的差异值。
这里，差异值可以是具体的宽度差异值，也可以是第二波束宽度与第一波束宽度的比例关系。
示例性的，如表1所示，波束变化指示可以通过一个比特为指示第二波束相对第一波束宽度增大还是减小，通过另一个比特为指示第二波束宽度与第一波束宽度的比例关系，即宽度变化因子。如此，通过波束变化指示可以显性地指示切换前后波束的差异。
在一个实施例中，所述切换请求包括：指示所述第一通信节点能力的 能力信息。
第一通信节点能力可以包括：第一通信节点可切换的波束宽度，以及从第一波束切换到第二波束在波束指向上的控制能力等。第二通信节点可以基于第一通信节点能力判断是否运行波束切换。
在一个实施例中，指示所述第一通信节点能力的所述能力信息，用于指示所述第一通信节点具有保证切换前后波束朝向一致性的能力，或者指示所述第一通信节点不具有保证切换前后波束朝向一致性的能力。。
不同第一通信节点具有不同的波束切换能力。一个实施例中，第一通信节点进行波束切换后可以确保切换后的波束指向与切换前的波束指向保证一致性，波束切换前后峰值增益方向基本一致，或者波束切换前后峰值增益方向偏差小于或等于偏差阈值。如图5所示，另一个实施例中，第一通信节点进行波束切换后，波束切换前后的峰值增益方向偏差角度大于或等于偏差阈值。如果波束切换前后的峰值增益方向偏差大于或等于偏差阈值，即切换后第二波束峰值增益方向与第二通信节点的偏差角度较大，从而降低信号传输质量。
如此，第一通信节点通过波束扫描请求信息请求采用第二波束进行波束扫描，确定满足传输需求的一个第二波束，可以减少由于波束类型切换产生的切换前后波束峰值增益方向不一致的情况，进而提高信号传输效率。
在一个实施例中，所述方法还包括：
接收携带有波束扫描请求信息的所述切换请求，其中，所述波束扫描请求信息，用于请求采用所述第二波束进行波束扫描的扫描资源。
第一通信节点可以在切换请求中携带波束扫描请求信息，用于向第二通信节点请求进行波束管理。这里，波束管理是指第一通信节点采用多个第二波束对第二通信节点发射的参考信号等信号进行扫描，确定信号满足预设条件的一个第二波束，将该第二波束作为第一通信节点和第二通信节 点之间通信的波束。
波束扫描请求信息可以用于向第二通信节点请求进行波束扫描的扫描资源。这里，扫描资源可以包括：扫频的时隙资源和频率资源等。
第二通信节点接收到切换请求后，如果允许进行波束切换，则可以确定用于第二波束扫描的扫描资源。
第一通信节点的能力信息可以作为一种波束扫描请求信息。例如，第一通信节点发送的能力信息指示第一通信节点进行波束切换前波束的峰值增益方向与进行波束切换后波束的峰值增益方向的偏差小于或等于偏差阈值。第二通信节点接收到波束扫描请求信息后可以确定第一通信节点需要进行第二波束的扫描。
通波束扫描可以确定出信号质量最优的第二波束用于第一通信节点和第二通信节点的通信，提高通信质量。
在一个实施例中，所述方法还包括：
响应于接收到携带有所述波束扫描请求信息的所述切换请求，发送携带有指示所述扫描资源的资源信息的切换响应。
这里，第二通信节点可以通过切换响应中携带的资源信息指示用于波束扫描的扫描资源，扫描资源可以包括：扫频的时隙资源和频率资源等。
第一通信节点接收到切换响应后，确定出扫描资源。并在扫描资源上，采用多个第二波束对第二通信节点发射的参考信号等信号进行扫描，确定扫描结果满足预设条件的一个第二波束，将该第二波束作为第一通信节点和第二通信节点之间通信的波束。这里，扫描结果，可以是采用第二波束进行扫描确定的第二通信节点发射的参考信号等信号的信号质量参数，如参考信号接收功率(RSRP，Reference Signal Receiving Power)等。
示例性的，第一通信节点可以采用第二波束进行扫描，确定RSRP最优的一个第二波束，将该信息传输用于第一通信节点和第二通信节点之间 的通信。
如此，第一通信节点采用第二波束进行波束扫描，确定满足传输需求的一个第二波束，可以减少由于波束类型切换产生的切换前后波束峰值增益方向不一致的情况，进而提高信号传输效率。
在一个实施例中，所述方法还包括：
响应于所述第一通信节点切换到所述第二波束，发送信号传输指示信息，其中，所述信号传输指示信息，用于指示在所述第二波束上发送信号的功率配置。
第二通信节点在第一通信节点完成切换波束后，还可以向第一通信节点下发根据第二波束重新调整相应的传输信号的配置，如信号传输功率配置等，这里，传输功率配置可以包括：移动性管理的测量间隔时间配置、信号发射功率配置等。
第一通信节点基于功率配置，在第二波束上进行数据通信。例如，根据功率配置所配置的测量间隔时间进行信号测量等。从而满足功率控制需求，进而节省电量。
在一个实施例中，所述方法还包括：
响应于接收到所述请求信息，发送指示允许切换到所述第二波束的切换响应。
第二通信节点可以根据波束变化指示确定是否允许第一通信节点从第一波束切换到第二波束。例如，可以根据第二波束的宽度等确定是否会与其他通信节点的波束产生干扰，确定是否允许第一通信节点从第一波束切换到第二波束。第二通信节点也可以根据自身负载情况确定是否允许第一通信节点从第一波束切换到第二波束；例如第二通信节点的负载大于负载阈值时，不允许第一通信节点从第一波束切换到第二波束。第二通信节点还可以根据第一通信节点的能力确定是否允许第一通信节点从第一波束切 换到第二波束；例如，当第一通信节点波束管理能力较弱，即第一通信节点进行波束切换前波束的峰值增益方向与进行波束切换后波束的峰值增益方向的偏差大于或等于偏差阈值，并且第一通信节点未在切换请求中携带波束扫描请求信息时，不允许第一通信节点从第一波束切换到第二波束。
第二通信节点可以发送指示允许进行波束切换的切换响应。第一通信节点接收到切换响应后，从第一波束切换到第二波束。如果没有接收到指示允许进行波束切换的切换响应，则不进行波束切换。
