图1是本申请实施例的一个应用场景的示意图。
如图1所示，通信系统100可以包括终端设备110和网络设备120。网络设备120可以通过空口与终端设备110通信。终端设备110和网络设备120之间支持多业务传输。
应理解，本申请实施例仅以通信系统100进行示例性说明，但本申请实施例不限定于此。也就是说，本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(Long Term Evolution，LTE)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、5G通信系统(也称为新无线(New Radio，NR)通信系统)，或未来的通信系统等。

网络设备120可以是长期演进(Long Term Evolution，LTE)系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是下一代无线接入网(Next Generation Radio Access Network，NG RAN)设备，或者是NR系统中的基站(gNB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备120可以为中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器，或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
终端设备110可以是任意终端设备，其包括但不限于与网络设备120或其它终端设备采用有线或者无线连接的终端设备。
例如，所述终端设备110可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备或者未来演进网络中的终端设备等。
终端设备110可以用于设备到设备(Device to Device，D2D)的通信。
无线通信系统100还可以包括与基站进行通信的核心网设备130，该核心网设备130可以是5G核心网(5G Core，5GC)设备，例如，接入与移动性管理功能(Access and Mobility Management Function，AMF)，又例如，认证服务器功能(Authentication Server Function，AUSF)，又例如，用户面功能(User Plane Function，UPF)，又例如，会话管理功能(Session Management Function，SMF)。可选地，核心网络设备130也可以是LTE网络的分组核心演进(Evolved Packet Core，EPC)设备，例如，会话管理功能+核心网络的数据网关(Session Management Function+Core Packet Gateway，SMF+PGW-C)设备。应理解，SMF+PGW-C可以同时实现SMF和PGW-C所能实现的功能。在网络演进过程中，上述核心网设备也有可能叫其它名字，或者通过对核心网的功能进行划分形成新的网络实体，对此本申请实施例不做限制。
通信系统100中的各个功能单元之间还可以通过下一代网络(next generation，NG)接口建立连接实现通信。
例如，终端设备通过NR接口与接入网设备建立空口连接，用于传输用户面数据和控制面信令； 终端设备可以通过NG接口1(简称N1)与AMF建立控制面信令连接；接入网设备例如下一代无线接入基站(gNB)，可以通过NG接口3(简称N3)与UPF建立用户面数据连接；接入网设备可以通过NG接口2(简称N2)与AMF建立控制面信令连接；UPF可以通过NG接口4(简称N4)与SMF建立控制面信令连接；UPF可以通过NG接口6(简称N6)与数据网络交互用户面数据；AMF可以通过NG接口11(简称N11)与SMF建立控制面信令连接；SMF可以通过NG接口7(简称N7)与PCF建立控制面信令连接。

应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种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，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
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，基站和终端之间通过指向性比较强的窄波束进行通信。
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，这种终端可称为终端具备公共的波束管理(Common Beam Management，CBM)能力或CBM能力终端。图4是本申请实施例提供的CBM能力终端的示例。如图4所示，CBM能力终端只有一组发射/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，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，但同一时刻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。
另外一种情况是：终端有两组(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，这种终端可称为终端具备独立的波束管理能力(Independent Beam Management，IBM)或IBM能力终端。图5是本申请实施例提供的IBM能力终端的示例。如图5所示，IBM能力终端有两组发射/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；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；在同一时刻下，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CBM能力终端，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CBM能力终端只能处于共站址场景的小区下，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IBM能力终端，由于同一时刻可以产生两个或多个独立波束，也即意味着同一时刻终端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IBM能力终端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能力终端有更高的灵活性，可以工作在不同的基站部署场景下，而CBM能力终端在网络中的应用场景比较受限。但是，从终端实现角度看，IBM能力终端由于需要具备多个发射/接收天线单元，其实现复杂度、成本及耗电都比CBM能力终端要高。因此，在实际网络中，终端大多从复杂度、成本、耗电以及灵活度等方面进行综合考量，并选择不同的实现方式。
为便于理解本申请的方案，下面对单频段下终端设备配置发射功率的方案进行说明。
针对单频段，终端设备的最大发射功率是通过最大峰值有效全向辐射功率(max peak Effective Isotropic Radiated Power，EIRP)、最大总辐射功率(max Total Radiated Power，max TRP)、最小峰值发射功率(min peak EIRP)以及球面覆盖(spherical coverage)等参数来限制的。其中，有效全向辐射功率(Effective Isotropic Radiated Power，EIRP)也称为等效全向辐射功率(Equivalent Isotropic Radiated Power，EIRP)。例如，发送设备的EIRP可以是接收端和发射端发射天线在波束中心轴向上辐射的功率，即可以将无线电发射机供给天线的功率与在给定方向上天线绝对增益的乘积，作为表征发射端的发射能力的指标。总辐射功率(Total Radiated Power，TRP)可以通过对整个辐射球面的发射功率进行积分并取平均得到，用于反映整机的发射功率情况，跟设备在传导情况下的发射功率和天线辐射性能有关。
图8是本申请实施例提供的单频段发射功率配置要求的示例。
如图8所示，终端在某个频段可以产生多个波束(通常同一时刻只有一个波束在工作)，对其最大发射功率的要求如下：
1.为了避免对处于通信方向的其它终端造成干扰，终端在最大发射功率方向(假设为波束(Beam)1)上允许发射的最大功率不能超过max peak EIRP，也即peak EIRP 1≤max Peak EIRP。由于Beam1的peak EIRP比其他Beam的peak EIRP大，因此也就意味着其他Beam也会满足max peak EIRP的要求。可选的，该max peak EIRP可来自政府监管机构的法规要求。
2.为了避免对其他方向的终端造成干扰，要求终端辐射波束在所有方向上的辐射功率总和不能超过max TRP，假设所有方向上辐射功率最大的波束为波束2，则波束2在各方向的辐射功率之和TRP 2≤max TRP。由于波束2的总辐射功率TRP比其他波束的要大，因此也就意味着其他波束也会满足max TRP的要求。可选的，该指标max TRP可来自政府监管机构的法规要求。
3.为了确保终端的上行覆盖能力，终端在最大发射功率方向(假设为Beam1)上发射的最大功率应至少达到min peak EIRP的要求。
4.为了确保终端的移动性及上行覆盖，要求在所有方向上的峰值发射功率的统计曲线应能达到球面覆盖(spherical coverage)要求，也即在累积分布函数(cumulative distribution function，CDF)曲线上某一百分比对应的峰值EIRP应高于门限值。图9是本申请实施例提供的球面覆盖要求的示例。如图9所示，CDF曲线上50％对应的峰值EIRP(即11.5)应高于门限值。
如上文所述，随着终端的能力的提升，CBM能力终端和IBM能力终端均有可能在同一时刻在多个频段上产生多个波束，且当前仅有单频段下终端设备配置发射功率的方案。然而，由于多个波束相互之间会产生增益，如果继续利用单频段下终端设备配置发射功率的方案对多频段下的终端设备的发射功率进行配置，有可能会导致发射功率的配置精度达不到要求。例如，当网络配置终端设备在多个频段上同时工作时如何进行终端的发射功率配置以达到同时满足多频段覆盖与降低干扰仍有待研究，即本领域亟需对终端设备的功率配置方案进行进一步完善。本申请通过对终端多频段同时工作场景下的功率交互原理的分析，对终端设备的最大发射功率进行配置，即提供一种配置发射功率的方法和终端设备，完善了终端设备的进行多频段功率配置方案，能够确保毫米波终端在多频段并行发射的情况下，其发射功率能够满足法规要求，同时确保上行覆盖。
如上文所述，在NR系统中的毫米波频段，通常终端采用波束赋形来集中发射功率，克服大的传播损耗，改善上下行覆盖能力，与此同时，需要保证终端的发射功率不能过大，以避免对其他方向上终端的干扰。由此引入了最大峰值EIRP、最大TRP、最小峰值EIRP以及球面覆盖等发射功率指标来对功率进行约束。
本申请中，终端当配置了载波聚合(Carrier Aggregation，CA)或双连接(Dual Connection，DC)等多频段同时发射时，其发射功率将会增大，需要考虑如何才能保证终端满足最大峰值EIRP、最大TRP、最小峰值EIRP以及球面覆盖等法规要求。在一些实施例中，最大峰值EIRP、最大TRP或最小峰值EIRP可按照每个频段单独要求，即终端只需在每个频段上按照单频段要求进行功率配置即可。在一些实施例中，最大峰值EIRP和/或最小峰值EIRP可按照终端总体要求，即终端需要综合考虑在 同一方向上所有同时发射的频段的功率，并使其满足最大峰值EIRP和/或最小峰值EIRP。在一些实施例中，最大TRP可按照终端总体要求，即终端需要确保同时发射的频段的总辐射功率不超过最大TRP。
图10是本申请实施例提供的配置发射功率的方法200的示意性流程图，所述方法200可以由终端设备执行，例如可以是如图1所示的终端设备，再如毫米波终端。
如图10所示，所述方法200可包括以下部分或全部内容：
S210，在多个频段并行发射的情况下，配置所述多个频段的发射功率满足发射功率要求。
例如，终端设备可基于所述多个频段并行发射的场景，为所述终端设备配置所述多个频段的发射功率满足发射功率要求。具体而言，终端设备可通过对所述多个频段并行发射的场景的分析，保证终端满足最大峰值EIRP、最大TRP、最小峰值EIRP以及球面覆盖等法规要求。例如，可通过对所述多个频段并行发射的场景的分析，确保终端设备在同一方向上所有同时发射的频段的功率，并使其满足最大峰值EIRP和/或最小峰值EIRP。基于此，使得终端设备满足上行覆盖要求，同时避免对其他用户干扰。
本申请提供的方案完善了终端设备的进行多频段功率配置方案，在多个频段并行发射的情况下，通过配置所述多个频段的发射功率满足发射功率要求，能够确保毫米波终端在多频段并行发射的情况下，其发射功率能够满足法规要求，同时确保上行覆盖。
在一些实施例中，所述S210可包括：
配置所述多个频段在同一方向上的总发射功率小于或等于最大峰值有效全向辐射功率EIRP，和/或配置所述多个频段在同一方向上的总发射功率大于或等于最小峰值EIRP。
换言之，最大峰值EIRP可按照终端总体要求，即针对终端设备的与方向性有很大关系的峰值EIRP的进行功率配置。
在一些实施例中，所述方法200还可包括：
将第一峰值EIRP和至少一个第一EIRP的和确定为所述多个频段在同一方向上的总发射功率；
其中，所述第一峰值EIRP为所述多个频段中的第一频段上的第一波束的峰值EIRP，所述第一波束为通过所述第一频段的波束赋形因子进行波束赋形所形成的波束，所述至少一个第一EIRP包括所述多个频段上的除所述第一波束之外的波束在所述第一峰值EIRP方向上的发射功率。
在一些实现方式中，所述方法200还可包括：
确定所述至少一个第一EIRP。
在一些实现方式中，确定所述第一频段对应的至少一个第一波束；将所述至少一个第一波束在所述第一峰值EIRP方向上的发射功率，确定为所述至少一个第一EIRP。可选的，所述至少一个第一波束包括利用所述第一频段的波束赋形因子分别对所述多个频段中除所述第一频段之外的至少一个频段进行波束赋形所形成的波束。可选的，所述方法应用于共站址场景或不共站址场景。可选的，所述方法应用于公共的波束管理CBM能力终端。
下面结合具体实施例，以CBM能力终端在共站部署和不共站部署下的利用最大峰值率EIRP配置发射功率的方案进行说明。
实施例1：
图11是本申请实施例提供的CBM能力终端在不同网络场景下的发射功率的示例。如图11所示，对于CBM能力终端，由于两个频段采用了相同的波束赋形因子，假设该波束赋形因子是基于频段1得到，因此频段1的波束1能够准确的指向目标基站1，而频段2的波束则与目标基站方向存在指向偏差。图12是本申请实施例提供的不同部署场景下的CBM能力终端最大发射功率的示例。如图12所示，不论是在共站部署情况下还是在不共站部署情况下，终端在两个频段并发时的最大发射功率(EIRP)是峰值EIRP 1+EIRP 3或峰值EIRP 2+EIRP 4。因此，在满足最大峰值EIRP指标上需考虑或确定峰值EIRP 1+EIRP 3以及峰值EIRP 2+EIRP 4，也就是说，实现本方案的问题在于如何得到EIRP 3及EIRP 4。
其中，EIRP 3是波束 2在峰值EIRP 1方向的功率强度，且EIRP 3≤峰值EIRP 2。同理，EIRP 4是波束 1在峰值EIRP 2方向的功率强度，且EIRP 4≤峰值EIRP 1。在本申请的一些实施例中，EIRP 3和EIRP 4的获取可通过下述方式之一得到：
通常情况下，终端只能产生有限的几个波束，通过对来波方向的测量来确定具体使用哪个波束进行收发，由此，可确定出需要考虑峰值EIRP 1还是需要考虑峰值EIRP 2。假设需要考虑峰值EIRP 1，即CBM能力终端其波束赋形因子是频段1对应的波束赋形因子，即通过频段1对应的波束赋形因子得到波束 1，同时将此波束赋形因子应用于频段2得到对应的波束 2，可以发现，频段1和频段2的波束具有一一对应关系。通过在波束 1的峰值方向上的波束 2发射功率(EIRP)，可得到相应的EIRP 3， 即波束 2在波束 1的峰值方向上的天线增益值。同理，通过在波束 2的峰值方向上的波束 1发射功率，可得到相应的EIRP 4，即波束 1在波束 2的峰值方向的天线增益值。下面结合表1进行是示例性的说明。
表1
Figure PCTCN2021082811-appb-000001
如表1所示，相比于单频段下终端设备配置发射功率的方案，当网络配置终端在频段1和频段2同时发射时，终端应配置波束 1和波束 2的发射功率，以确保峰值EIRP 1+EIRP 3≤最大峰值EIRP，且峰值EIRP 2+EIRP 4≤最大峰值EIRP。
当然，也可在上述方式的基础上做简化可以得到下述方式：
通过对波束 1和波束 2的峰值EIRP的校准可简化相应的发射功率约束条件。下面结合表2进行是示例性的说明。
表2
Figure PCTCN2021082811-appb-000002
如表2所示，相比于单频段下终端设备配置发射功率的方案，当网络配置频段1和频段2同时发射时，终端应配置频段1上的发射波束和频段2上的发射波束的总发射功率，以确保峰值EIRP 1+峰值EIRP 2≤最大峰值EIRP。
在另一些实现方式中，确定所述多个频段中除所述第一频段之外的至少一个频段采用的至少一个第二波束；将所述至少一个第二波束在所述第一峰值EIRP方向上的发射功率，确定为所述至少一个第一EIRP。可选的，所述至少一个第二波束包括利用至少一个波束赋形因子分别对所述至少一个频段进行波束赋形所形成的波束，所述至少一个波束赋形因子和所述至少一个频段一一对应。可选的，所述方法应用于不共站址场景。可选的，所述方法应用于独立的波束管理IBM能力终端。
下面结合具体实施例，以IBM能力终端在共站部署和不共站部署下的利用最大峰值率EIRP配置发射功率的方案进行说明。
实施例2：
图13是本申请实施例提供的IBM能力终端在不同网络场景下的发射功率的示例。如图13所示，对于IBM能力终端，由于两个频段可以采用独立的波束赋形因子，且波束赋形因子是基于对应基站得到，因此两个波束均能够准确指向目标基站。图14是本申请实施例提供的不同部署场景下的IBM能力终端最大发射功率的示例。如图14所示，由于在共站部署情况下和在不共站部署情况下的IBM能力终端具有不同指向的波束，因此，需要基于不同的场景确定不同的配置要求。具体地，在共站部署情况下，IBM能力终端在两个频段并发时的最大发射功率(EIRP)是峰值EIRP1+峰值EIRP2，相应的需要满足峰值EIRP1+峰值EIRP2≤最大峰值EIRP；在不共站部署情况下，两个频段并发时的最大发射功率(EIRP)是峰值EIRP1+EIRP3或峰值EIRP2+EIRP4，此时需要满足峰值EIRP1+EIRP3≤最大峰值EIRP以及峰值EIRP2+EIRP4≤最大峰值EIRP。
其中，EIRP 3是波束 2在峰值EIRP 1方向的功率强度，且EIRP 3≤峰值EIRP 2。同理，EIRP 4是波束 1在峰值EIRP 2方向的功率强度，且EIRP 4≤峰值EIRP 1。在本申请的一些实施例中，对于不共站部署的EIRP 3及EIRP 4的获取可以通过类似CBM能力终端方式下的方式得到：
通常情况下，终端只能产生有限的几个波束，通过对来波方向的测量来确定具体使用哪个波束进行收发。IBM能力终端可基于频段1对应的波束赋形因子对频段1进行赋形并得到波束 1，根据频段2对应的波束赋形因子对频段2进行赋形并得到波束 2。因此，频段1和频段2的波束并不具有一一对应关系。换言之，波束 1对应的EIRP 3将不同于CBM能力终端下的唯一值，而是取决于频段2对应的波束赋形因子，即EIRP 3跟所采用的频段2上的波束有关。波束 2对应的EIRP 4也类似。通过在波束 1的峰值方向上的波束 2发射功率(EIRP)，可得到相应的EIRP 3，即波束 2在波束 1的峰值方向 上的天线增益值。同理，通过在波束 2的峰值方向上的波束 1发射功率，可得到相应的EIRP 4，即波束 1在波束 2的峰值方向的天线增益值。下面结合表3进行是示例性的说明。
表3
Figure PCTCN2021082811-appb-000003
如表3所示，相比于单频段下终端设备配置发射功率的方案，当网络配置频段1和频段2同时发射波束 1和波束 2时，终端应配置波束 1和波束 2的发射功率，以确保峰值EIRP 1+EIRP 3≤最大峰值EIRP，且峰值EIRP 2+EIRP 4≤最大峰值EIRP。
当然，在一种实现方式中，也可在上述方式的基础上做简化可以得到下述方式：
通过对波束 1和波束 2的峰值EIRP的校准可简化相应的发射功率约束条件。下面结合表4进行是示例性的说明。

如表4所示，相比于单频段下终端设备配置发射功率的方案，当网络配置频段1和频段2同时发射时，终端应配置频段1上的发射波束和频段2上的发射波束的总发射功率，以确保峰值EIRP m+峰值EIRP n≤最大峰值EIRP。
当然，在另一种实现方式中，也可在上述方式的基础上做简化可以得到下述方式：
通过对波束 1和波束 2的峰值EIRP的校准可简化相应的发射功率约束条件。下面结合表5进行是示例性的说明。
表5
Figure PCTCN2021082811-appb-000005
如表5所示，相比于单频段下终端设备配置发射功率的方案，当网络配置频段1和频段2同时发射时，终端应配置频段1上的发射波束和频段2上的发射波束的最大发射波束的总发射功率，以确保峰值EIRP max1+峰值EIRP max2≤最大峰值EIRP。
在一些实施例中，所述方法200还可包括：
将多个峰值EIRP的和确定为所述多个频段在同一方向上的总发射功率，所述多个峰值EIRP分别为所述多个频段上的波束的峰值EIRP。
例如，如表2或表4所示的方案，以所述多个频段包括频段1和频段2为例，终端设备可以配置频段1上的发射波束和频段2上的发射波束的总发射功率，以确保峰值EIRP m+峰值EIRP n≤最大峰值EIRP。
在一些实现方式中，所述方法应用于不共站址场景。当然，也可应用于共站址场景。
在一些实现方式中，所述方法应用于独立的波束管理IBM能力终端。当然，也可应用于CBM能力终端。
在一些实施例中，所述S210可包括：

波束在所有方向上的辐射功率之和小于或等于最大总辐射功率TRP；
波束的最大发射功率大于或等于最小峰值EIRP；或
在所有方向上的峰值EIRP的统计曲线满足球面覆盖要求。
需要说明的是，本申请实施例中，每一个频段满足单频段发射功率要求可以理解为每一个频段作为一个整体满足单频段发射功率要求，即每一个频段上的所有波束作为一个整体满足单频段发射功率要求。例如，当一个频段发射多个波束时，所述波束的最大发射功率可以是：针对所述一个频段上的所有波束(即所述多个波束)而言，最大发射功率方向上的发射功率；类似的，所述波束在所有方向上的辐射功率之和可以是：所述一个频段上的所有波束(即所述多个波束)在所有方向上的辐射功率之和。
