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：蜂窝移动通信系统中的手机终端，以及网络侧设备，如基站等接入网设备，以及核心网等。
通常，可以采用功率等级(PC，Power Class)指示最大发射功率，NR单载波系统中的功率等级包括：PC5(20dBm)、PC3(23dBm)、PC2(26dBm)、PC1.5(29dBm)和PC1(31dBm)。
随着比吸收率(SAR，Specific Absorption Rate)的问题通过功率管理最大功率衰减(P-MPR，Power Management Maximum Power Reduction)和占空比的方式被解决后，高功率终端也被应用于多载波系统中。
多载波系统中发射功率可以由不同频段下单载波的发射功率叠加得到。目前，多载波系统中高功率(PC2)包括：PC3加PC3、PC3加PC2、PC2加PC3、PC2加PC3、PC2加PC2对应频段组合，更高功率可以通过PC3、PC2和PC1.5之间的不同组合得到，例如，可以包括PC3加PC1.5、PC2加PC1.5、PC1.5加PC1.5等对应频段组合。
多载波系统中，演进型陆地无线接入和新空口双连接(EN-DC，Evolved terrestrial radio access New radio–Dual Connectivity)接系统终端可以上报聚合的功率等级(EN-DC功率等级)，以及分别上报双连接中的LTE和NR的功率等级，NR单载波功率等级。如表1所示。表1同时表明了各功率等级所采用的信息单元。
表1
Figure PCTCN2021141705-appb-000001
在NR多载波系统中，终端只上报载波聚合(CA，Carrier Aggregation)的功率等级，即最大叠加发射功率，且不上报载波聚合中每个频段的功率等级。载波聚合的功率等级以及每个频段的功率等级可如表2所示。
表2
Figure PCTCN2021141705-appb-000002
Figure PCTCN2021141705-appb-000003
表2中，最大叠加发射功率的功率等级是指定的，即最大叠加发射功率并非全都是载波聚合工作模式下各频段上的发射功率进行叠加得到的。
终端在某些频段的功率等级在载波聚合工作模式中和单载波工作模式中出现不一致的情况，是由于上行发射分集的应用而导致的。
如在单载波工作模式中某频段工作的功率等级为26dBm(PC2)是通过发射分集(TxD，Transport Diversity)实现的，如果射频实现有两个发射(Tx)时，在上行载波聚合的工作模式中，此频段只能工作在23dBm(PC3)的功率等级，但是载波聚合系统中，不会单独上报每个频段在载波聚合工作模式中的功率等级。因此，基站在载波聚合的工作模式下无法区分某些频段上功率等级的提升是否是由于上行分集带来的。
在多载波系统中，最大叠加发射功率进一步提升，可达到的最大叠加发射功率如表3所示。现有的功率等级无法准确指示实际的最大叠加发射功率。
表3
Figure PCTCN2021141705-appb-000004
因此，在多载波系统中，如何准确上报多载波的叠加最大功率，以及当各频段在单载波工作模式和载波聚合工作模式中的功率等级不一致时，可以区分上行分集带来的功率提升，是亟待解决的问题。
如图2所示，本示例性实施例提供一种信息传输方法，可以被蜂窝移 动通信系统的终端执行，包括：
步骤201：发送功率指示信息，其中，所述功率指示信息，用于确定所述终端在多载波系统中N个频段的最大叠加发射功率。
其中，N为大于或等于1的正整数。
这里，多载波系统包括但不限于通过NR的多个载波聚合进行通信的蜂窝移动通信系统，可以包括：载波聚合技术系统、双链接技术(DC，Dual connectivity)系统、多接入系统的双链接技术(MRDC，Muti-RAT dual connectivity)系统，如EN-DC和NE-DC等。
载波聚合技术可以将多个载波聚合在一起，实现更大传输带宽，有效提高了上下行传输速率。如图3所示，一个载波的带宽为20MHz，聚合5个载波可以达到100MHz的传输带宽。终端可以根据自己的能力大小决定最多可以同时利用的载波数量。
通过多个载波聚合可以提升传输带宽，提升传输速率。多个载波聚合可以是不同频段的多个载波聚合，也可以是单个频段中多个载波聚合。例如：多个载波聚合可以是频段A和频段B两个频段中的多个载波聚合。
这里。最大叠加发射功率可以是在多载波系统中，终端通过载波聚合工作模式下发射信号时多个载波发射功率的叠加值。其中，最大叠加发射功率可以是多个频段中的多个载波发射功率的叠加值，或单个频段中的多个载波发射功率的叠加值。
所述最大叠加发射功率可不同于第一类功率等级指示的发射功率。
第一类功率等级可以是相关技术中的功率等级。第一类功率等级及其指示的功率如表4所示。
表4
第一类功率等级 相应的功率
PC1 31dBm
PC1.5 29dBm
PC2 26dBm
PC3 23dBm
PC5 20dBm
示例性地，所述功率指示信息指示的发射功率可为表4所述的最大叠加发射功率以外的任意叠加发射功率值。
当终端在单载波工作模式下的发射功率达到表5所示的功率等级情况下，在多载波系统中，即终端在载波聚合工作模式下，可达到的最大叠加发射功率如表5所示。这里，用于叠加的单载波工作模式下的发射功率，可以是非分集的发射功率。
表5
Figure PCTCN2021141705-appb-000005
结合表4和表5，可以确定第一类功率等级PC1、PC1.5、PC2、PC3和PC5均无法指示表5中的最大叠加发射功率。
这里，终端可以向基站发送功率指示信息，功率指示信息可以用于供基站确定PC1、PC1.5、PC2、PC3和PC5无法指示任意一个的最大叠加发射功率，如27.8dBm、30dBm、30.8dBm和32dBm等。
这里，功率指示信息可以直接指示最大叠加发射功率，也可以向基站提供用于确定最大叠加发射功率的关联信息，如终端在单载波工作模式下的发射功率的功率等级等，由基站确定实际的最大叠加发射功率。
如此，通过功率指示信息确定第一类功率等级无法指示的最大叠加发射功率，提高了最大叠加发射功率指示的准确性。基站基于通过功率指示信息确定的最大叠加发射功率为终端进行配置，提高基站配置的准确性。
在一个实施例中，通过功率指示信息确定的最大叠加发射功率，包括：终端在载波聚合工作模式下各频段上的发射功率进行线性叠加得到的。
通过功率指示信息确定的最大叠加发射功率可以是指定的发射功率，也可以是是终端在载波聚合工作模式下各频段上的发射功率进行线性叠加的实际功率。即最大叠加发射功率可以是终端在载波聚合工作模式下各频段上的发射功率累加的结果。而相关技术中，由于第一类功率等级无法准确指示最大叠加发射功率，因此，最大叠加发射功率的功率等级是指定的，即最大叠加发射功率并非全都是载波聚合工作模式下各频段上的发射功率进行叠加得到的。
这里，线性叠加是指在多载波系统中，最大叠加发射功率是终端在载波聚合工作模式下各频段上的发射功率累加得到的，并非基于终端在载波聚合工作模式下各频段上的发射功率或单载波模式下各频段上的发射功率指定的。而指定的功率等级对应的最大叠加发射功率并不一定等于终端在载波聚合工作模式下各频段上的发射功率的叠加值。
如此，通过功率指示信息确定的最大叠加发射功率，真实反应终端在在多载波系统中，即终端在载波聚合工作模式下的实际发射功率，提高了最大叠加发射功率指示的准确性。基站基于通过功率指示信息确定的最大叠加发射功率为终端进行配置，提高基站配置的准确性。
在一个实施例中，所述功率指示信息，包括：
第一指示，指示所述最大叠加发射功率的第二类功率等级，其中所述第二类功率等级不同于第一类功率等级。
这里，在多载波系统中，可以根据终端在载波聚合工作模式下各频段上的发射功率进行叠加得到的最大叠加发射功率定义第二类功率等级。第二类功率等级可以用于指示第一类功率等级无法指示的发射功率。
示例性的，可以采用IE：powerClass-v1xxx承载第二类功率等级。第二 类功率等级可以是：{PCv，PCz，PCy，PCx，…}，
示例性的，PCv、PCz、PCy和PCx等，分别用于指示不同的发射功率。
例如，PCv、PCz、PCy和PCx可以分别用于指示如表6所示的最大叠加发射功率。
表6
Figure PCTCN2021141705-appb-000006
通过第二类功率等级指示的最大叠加发射功率可以是线性叠加的终端在载波聚合工作模式下各频段上的发射功率。如果基于终端上报的单载波工作模式中的功率等级确定最大叠加发射功率，并且终端在某频段上同时上报支持发射分集，则终端在该频段上单载波工作模式中的功率等级应该减3dB，得到载波聚合工作模式下该频段上的发射功率，再进行叠加。
示例性的，IE：ue-PowerClass可以用于承载终端在单载波工作模式中的功率等级。如果Band A上报IE：ue-PowerClass PC2，并且Band A支持发射分集，Band B上报IE：ue-PowerClass PC2，那么，终端在Band A载波聚合工作模式下的功率等级为PC3，终端在Band B载波聚合工作模式下的功率等级为PC2，两者叠加的功率为27.8dBm。根据表6的对应关系，此时终端应该通过IE：powerClass-v1xxx上报PCx。
当Band A上报IE：ue-PowerClass PC2，Band B上报IE：ue-PowerClass PC2，此时终端应该通过IE：powerClass-v1610上报PC1.5。
如此，通过第二类功率等级指示实际的最大叠加发射功率，提高了最大叠加发射功率指示的准确性。基站基于通过功率指示信息确定的最大叠加发射功率为终端进行配置，提高基站配置的准确性。
在一个实施例中，所述功率指示信息，包括：
第二指示，指示所述最大叠加发射功率等于终端支持的N个频段上的发射功率的线性叠加值；
第二指示可以用于泛指最大叠加发射功率，例如可以用PC0泛指最大叠加发射功率，PC0并不代表具体的功率值。第二指示所指示的最大叠加发射功率可以是终端在载波聚合工作模式下各频段上的发射功率的线性叠加得到的。
这里，线性叠加是指发射功率通过累加得到最大叠加发射功率，而非基于终端在载波聚合工作模式下各频段上的发射功率指定一个功率等级，而指定的功率等级对应的功率并不一定等于终端在载波聚合工作模式下各频段上的发射功率的叠加值。例如，终端在载波聚合工作模式下两个频段上的发射功率分别是PC3:23dBm和PC2:26dBm，那么线性叠加后的最大叠加发射功率为27.8dBm；而相关技术中，指定的最大叠加发射功率可以是PC2或PC3等。
示例性的，可以采用IE：powerClass-v1xxx承载第二指示，承载第二类功率等级可以是：{pc0}，PC0不代表具体的功率值。
PC0可以用于泛指表7所示的由终端在载波聚合工作模式下各频段上的发射功率的线性叠加得到的最大叠加发射功率。
表7
Figure PCTCN2021141705-appb-000007
示例性的，IE：ue-PowerClass可以用于承载单载波工作模式中的功率等级。如果Band A上报IE：ue-PowerClass PC2，并且Band A支持发射分 集，Band B上报IE：ue-PowerClass PC2，那么，终端在Band A载波聚合工作模式下的功率等级为PC3，终端在Band B载波聚合工作模式下的功率等级为PC2，两者叠加的功率为27.8dBm。根据表7的对应关系，此时终端应该通过IE：powerClass-v1xxx上报PC0。
当Band A上报IE：ue-PowerClass PC2，Band B上报IE：ue-PowerClass PC2，此时终端应该通过IE：powerClass-v1610上报PC1.5。
基站接收到第二指示，可以确定由终端在载波聚合工作模式下各频段上的发射功率的线性叠加得到的最大叠加发射功率。
如此，基于第二指示确定最大叠加发射功率，提高了确定最大叠加发射功率指示准确性。基站基于通过功率指示信息确定的最大叠加发射功率为终端进行配置，提高基站配置的准确性。
在一个实施例中，所述功率指示信息，包括：
第三指示，指示所述终端是否支持N个频段上的发射功率的线性叠加。
示例性的，如表8所示，可以采用IE：sumPowerUL-CA-r17或fullPowerUL-CA-r17承载第三指示。
表8
Figure PCTCN2021141705-appb-000008
第三指示用于指示终端在载波聚合工作模式下各频段上的发射功率的叠加能力。如果第三指示指示终端在载波聚合工作模式下各频段上的发射功率的具有叠加能力，那么，可以通过终端在载波聚合工作模式下各频段上的发射功率进行叠加得到的最大叠加发射功率。否则，可以采用相关技 术中指定的功率等级确定最大叠加发射功率。
示例性，第三指示的可以用{supported}指示终端支持N个频段上的发射功率的线性叠加，如果第三指示为缺省值，那么，可以确定终端不支持N个频段上的发射功率的线性叠加
示例性，如果IE：sumPowerUL-CA-r17或fullPowerUL-CA-r17为缺省值，那么网络则根据相关技术中的IE：powerClass-v1530或者powerClass-v1610确定最大叠加发射功率，并为终端配置相应的功率；如果终端上报IE：sumPowerUL-CA-r17或fullPowerUL-CA-r17为supported，网络则终端在单载波工作模式下各频段上的发射功率进行叠加得到的最大叠加发射功率为该终端配置相应的功率。如果终端在某频段上单载波工作模式下同时上报支持发射分集，那么，终端在该频段上的发射功率需要减3dB后进行叠加。
示例性的，IE：ue-PowerClass可以用于承载单载波工作模式中的功率等级。如果Band A上报IE：ue-PowerClass PC2，并且Band A支持发射分集，Band B上报IE：ue-PowerClass PC2，那么，终端在Band A载波聚合工作模式下的功率等级为PC3，终端在Band B载波聚合工作模式下的功率等级为PC2，两者叠加的功率为27.8dBm。
在一个实施例中，所述方法还包括：响应于所述功率指示信息包括所述第二指示或第三指示，基站线性叠加所述终端支持的N个频段上的发射功率，得到所述最大叠加发射功率。
这里，N个频段上的发射功率可以是终端在载波聚合工作模式下各频段上的发射功率。
由于第二指示或第三指示并未指示最大叠加发射功率或最大叠加发射功率的功率等级，只直接或间接指示最大叠加发射功率可以通过终端在载波聚合工作模式下各频段上的发射功率线性叠加得到。因此，基站可以将 终端在载波聚合工作模式下各频段上的发射功率进行线性叠加，确定最大叠加发射功率。
基站还可以基于确定的最大叠加发射功率，确定最大叠加发射功率对应的功率等级。最大叠加发射功率对应的功率等级可以是第一类功率等级或第二类功率等级。
如此，基于第二指示或第三指示确定最大叠加发射功率，提高了确定最大叠加发射功率指示准确性。基站基于通过功率指示信息确定的最大叠加发射功率为终端进行配置，提高基站配置的准确性。
在一个实施例中，所述功率指示信息，还用于指示所述终端在所述多载波系统中支持的每个频段的发射功率。
这里，终端在所述多载波系统中支持的每个频段的发射功率，可以是终端在载波聚合工作模式下各频段上的发射功率。
相关技术中，终端可以上报在单载波工作模式下的发射功率的功率等级。在单载波工作模式下，终端可以采用发射分集的方式进行发射。例如，终端具有两个发射(TX)，采用发射分集时发射功率为PC2(26dBm)。而在多载波系统中，采用载波聚合工作模式下每个频段下发射功率需要减去3dB。
这里，基站接收到终端上报的在单载波工作模式下的发射功率，以及载波聚合工作模式下每个频段下发射功率，可以确定终端在单载波工作模式下是否采用发射分集。
示例性的，终端上报的在单载波工作模式下的发射功率的功率等级为PC2，即26dBm，终端上报的在所述多载波系统中支持的某频段的发射功率为23dBm，有此可以确定在单载波工作模式下的采用了发射分集。
如此，结合功率指示信息指示的多载波系统中支持的每个频段的发射功和单载波工作模式的发射功率，终端可以区分上行发射分集带来的功率 的提升。
在一个实施例中，所述功率指示信息，用于指示所述终端在所述多载波系统中支持的每个频段的所述发射功率的所述第一类功率等级或第二类功率等级。
这里，功率指示信息指示的终端在多载波系统中支持的每个频段的发射功率可以是功率等级。每个频段的发射功率可以是功率等级可以是第一类功率等级或第二类功率等级。
示例性的，可以采用IE：ue-PowerClass-CA-r17承载多载波系统中支持的每个频段的发射功率的功率等级。承载的功率等级可以是{pc1，pc1.5，pc2，pc3，pc4，pc5…}。
示例性的，结合采用第一指示指示所述最大叠加发射功率的第二类功率等级，采用IE：powerClass-v1xxx承载第二类功率等级，以及采用IE：ue-PowerClass-CA-r17承载多载波系统中支持的每个频段的发射功率的功率等级。功率指示信息指示的内容可以如表9所示。

如图4所示，本示例性实施例提供一种信息传输方法，可以被蜂窝移动通信系统的基站执行，包括：

结合表4和表5，可以确定第一类功率等级PC1、PC1.5、PC2、PC3 和PC5均无法指示表5中的最大叠加发射功率。

这里，在多载波系统中，可以根据终端在载波聚合工作模式下各频段上的发射功率进行叠加得到的最大叠加发射功率定义第二类功率等级。第二类功率等级可以用于指示第一类功率等级无法指示的发射功率。
示例性的，可以采用IE：powerClass-v1xxx承载第二类功率等级。第二类功率等级可以是：{PCv，PCz，PCy，PCx，…}，
示例性的，PCv、PCz、PCy和PCx等，分别用于指示不同的发射功率。
例如，PCv、PCz、PCy和PCx可以分别用于指示如表6所示的最大叠加发射功率。
通过第二类功率等级指示的最大叠加发射功率可以线性叠加的终端在载波聚合工作模式下各频段上的发射功率。如果基于终端上报的单载波工作模式中的功率等级确定最大叠加发射功率，并且终端在某频段上同时上报支持发射分集，则终端在该频段上单载波工作模式中的功率等级应该减3dB，得到载波聚合工作模式下该频段上的发射功率，再进行叠加。
示例性的，IE：ue-PowerClass可以用于承载终端在单载波工作模式中的功率等级。如果Band A上报IE：ue-PowerClass PC2，并且Band A支持发射分集，Band B上报IE：ue-PowerClass PC2，那么，终端在Band A载波聚合工作模式下的功率等级为PC3，终端在Band B载波聚合工作模式下的功率等级为PC2，两者叠加的功率为27.8dBm。根据表6的对应关系，此时终端应该通过IE：powerClass-v1xxx上报PCx。
当Band A上报IE：ue-PowerClass PC2，Band B上报IE：ue-PowerClass  PC2，此时终端应该通过IE：powerClass-v1610上报PC1.5。
如此，通过第二类功率等级指示实际的最大叠加发射功率，提高了最大叠加发射功率指示的准确性。基站基于通过功率指示信息确定的最大叠加发射功率为终端进行配置，提高基站配置的准确性。
在一个实施例中，所述功率指示信息，包括：
第二指示，指示所述最大叠加发射功率等于终端支持的N个频段上的发射功率的线性叠加值。
第二指示可以用于泛指最大叠加发射功率，例如可以用PC0泛指最大叠加发射功率，PC0并不代表具体的功率值。第二指示所指示的最大叠加发射功率可以是终端在载波聚合工作模式下各频段上的发射功率的线性叠加得到的。
这里，线性叠加是指发射功率通过累加得到最大叠加发射功率，而非基于终端在载波聚合工作模式下各频段上的发射功率指定一个功率等级，而指定的功率等级对应的功率并不一定等于终端在载波聚合工作模式下各频段上的发射功率的叠加值。例如，终端在载波聚合工作模式下两个频段上的发射功率分别是PC3:23dBm和PC2:26dBm，那么线性叠加后的最大叠加发射功率为27.8dBm；而相关技术中，指定的最大叠加发射功率可以是PC2或PC3等。
示例性的，可以采用IE：powerClass-v1xxx承载第二指示，承载第二类功率等级可以是：{pc0}，PC0不代表具体的功率值。
PC0可以用于泛指表7所示的由终端在载波聚合工作模式下各频段上的发射功率的线性叠加得到的最大叠加发射功率。
示例性的，IE：ue-PowerClass可以用于承载单载波工作模式中的功率等级。如果Band A上报IE：ue-PowerClass PC2，并且Band A支持发射分集，Band B上报IE：ue-PowerClass PC2，那么，终端在Band A载波聚合 工作模式下的功率等级为PC3，终端在Band B载波聚合工作模式下的功率等级为PC2，两者叠加的功率为27.8dBm。根据表7的对应关系，此时终端应该通过IE：powerClass-v1xxx上报PC0。
当Band A上报IE：ue-PowerClass PC2，Band B上报IE：ue-PowerClass PC2，此时终端应该通过IE：powerClass-v1610上报PC1.5。
基站接收到第二指示，可以确定由终端在载波聚合工作模式下各频段上的发射功率的线性叠加得到的最大叠加发射功率。
如此，基于第二指示确定最大叠加发射功率，提高了确定最大叠加发射功率指示准确性。基站基于通过功率指示信息确定的最大叠加发射功率为终端进行配置，提高基站配置的准确性。
在一个实施例中，所述功率指示信息，包括：
第三指示，指示所述终端是否支持N个频段上的发射功率的线性叠加。
示例性的，如表8所示，可以采用IE：sumPowerUL-CA-r17或fullPowerUL-CA-r17承载第三指示。
第三指示用于指示终端在载波聚合工作模式下各频段上的发射功率的叠加能力。如果第三指示指示终端在载波聚合工作模式下各频段上的发射功率的具有叠加能力，那么，可以通过终端在载波聚合工作模式下各频段上的发射功率进行叠加得到的最大叠加发射功率。否则，可以采用相关技术中指定的功率等级确定最大叠加发射功率。
示例性，第三指示的可以用{supported}指示终端支持N个频段上的发射功率的线性叠加，如果第三指示为缺省值，那么，可以确定终端不支持N个频段上的发射功率的线性叠加
示例性，如果IE：sumPowerUL-CA-r17或fullPowerUL-CA-r17为缺省值，那么网络则根据相关技术中的IE：powerClass-v1530或者powerClass-v1610确定最大叠加发射功率，并为终端配置相应的功率；如果 终端上报IE：sumPowerUL-CA-r17或fullPowerUL-CA-r17为supported，网络则终端在单载波工作模式下各频段上的发射功率进行叠加得到的最大叠加发射功率为该终端配置相应的功率。如果终端在某频段上单载波工作模式下同时上报支持发射分集，那么，终端在该频段上的发射功率需要减3dB后进行叠加。
示例性的，IE：ue-PowerClass可以用于承载单载波工作模式中的功率等级。如果Band A上报IE：ue-PowerClass PC2，并且Band A支持发射分集，Band B上报IE：ue-PowerClass PC2，那么，终端在Band A载波聚合工作模式下的功率等级为PC3，终端在Band B载波聚合工作模式下的功率等级为PC2，两者叠加的功率为27.8dBm。
在一个实施例中，所述方法还包括：响应于所述功率指示信息包括所述第二指示或第三指示，基站线性叠加所述终端支持的N个频段上的发射功率，得到所述最大叠加发射功率。
这里，N个频段上的发射功率可以是终端在载波聚合工作模式下各频段上的发射功率。
由于第二指示或第三指示并未指示最大叠加发射功率或最大叠加发射功率的功率等级，只直接或间接指示最大叠加发射功率可以通过终端在载波聚合工作模式下各频段上的发射功率线性叠加得到。因此，基站可以将终端在载波聚合工作模式下各频段上的发射功率进行线性叠加，确定最大叠加发射功率。
基站还可以基于确定的最大叠加发射功率，确定最大叠加发射功率对应的功率等级。最大叠加发射功率对应的功率等级可以是第一类功率等级或第二类功率等级。
如此，基于第二指示或第三指示确定最大叠加发射功率，提高了确定最大叠加发射功率指示准确性。基站基于通过功率指示信息确定的最大叠 加发射功率为终端进行配置，提高基站配置的准确性。
在一个实施例中，如图5所示，所述方法还包括：
步骤501：基站基于所述功率指示信息确定的最大叠加发射功率，配置终端的上行功率。
基站可以基于最大叠加发射功率配置终端的上行功率。一方面，满足基站所需的信噪比或误码率，另一方面，通过调节上行功率以同个通信系统中同频信道干扰。
步骤501可以单独实施，也可以与步骤401结合实施。
在一个实施例中，所述功率指示信息，还用于指示所述终端在所述多载波系统中支持的每个频段的发射功率。
这里，终端在所述多载波系统中支持的每个频段的发射功率，可以是终端在载波聚合工作模式下各频段上的发射功率。
相关技术中，终端可以上报在单载波工作模式下的发射功率的功率等级。在单载波工作模式下，终端可以采用发射分集的方式进行发射。例如，终端具有两个发射(TX)，采用发射分集时发射功率为PC2(26dBm)。而在多载波系统中，采用载波聚合工作模式下每个频段下发射功率需要减去3dB。
这里，基站接收到终端上报的在单载波工作模式下的发射功率，以及载波聚合工作模式下每个频段下发射功率，可以确定终端在单载波工作模式下是否采用发射分集。
示例性的，终端上报的在单载波工作模式下的发射功率的功率等级为PC2，即26dBm，终端上报的在所述多载波系统中支持的某频段的发射功率为23dBm，有此可以确定在单载波工作模式下的采用了发射分集。
如此，结合功率指示信息指示的多载波系统中支持的每个频段的发射功和单载波工作模式的发射功率，终端可以区分上行发射分集带来的功率 的提升。
在一个实施例中，所述功率指示信息，用于指示所述终端在所述多载波系统中支持的每个频段的发射功率的所述第一类功率等级或第二类功率等级。
这里，功率指示信息指示的终端在多载波系统中支持的每个频段的发射功率可以是功率等级。每个频段的发射功率可以是功率等级可以是第一类功率等级或第二类功率等级。
示例性的，可以采用IE：ue-PowerClass-CA-r17承载多载波系统中支持的每个频段的发射功率的功率等级。承载的功率等级可以是{pc1，pc1.5，pc2，pc3，pc4，pc5…}。
示例性的，结合采用第一指示指示所述最大叠加发射功率的第二类功率等级，采用IE：powerClass-v1xxx承载第二类功率等级，以及采用IE：ue-PowerClass-CA-r17承载多载波系统中支持的每个频段的发射功率的功率等级。功率指示信息指示的内容可以如表9所示。
示例性的，结合采用第二指示泛指最大叠加发射功率，即采用IE：powerClass-v1xxx承载第二指示，以及采用IE：ue-PowerClass-CA-r17承载多载波系统中支持的每个频段的发射功率的功率等级。功率指示信息指示的内容可以如表10所示。
示例性的，结合第三指示用于指示终端在载波聚合工作模式下各频段上的发射功率的叠加能力，采用IE：sumPowerUL-CA-r17或fullPowerUL-CA-r17承载第三指示，以及采用IE：ue-PowerClass-CA-r17承载多载波系统中支持的每个频段的发射功率的功率等级。功率指示信息指示的内容可以如表11所示。
以下结合上述任意实施例提供一个具体示例：
如何上报聚合的功率等级是按照各频段上的最大发射功率进行叠加的
1：在多载波系统中，根据最大叠加发射功率定义新的功率等级。例如IE：powerClass-v1xxx：{pcv，pcz，pcy，pcx，…}，如PCx(27.8dBm)，PCy(30dBm)，PCz(30.8dBm)，PCv(32dBm)，。。。，叠加功率是根据各频段在单载波工作模式中的功率等级叠加的。如果终端在某频段上同时上报支持发射分集(Tx diversity)，则终端在该频段上的功率等级应该减3dB。例如Band A上报IE：ue-PowerClass PC2并且支持发射分集，Band B上报IE：ue-PowerClass PC2，此时终端应该通过IE：powerClass-v1xxx上报PCx(27.8dBm)；当Band A上报IE：ue-PowerClass PC2，Band B上报IE：ue-PowerClass PC2，此时终端应该通过IE：powerClass-v1610上报PC1.5。
2：结合1并定义终端在多载波系统中各频段支持的功率等级，如IE：ue-PowerClass-CA-r17：{pc1，pc1.5，pc2，pc3，pc4，pc5}。指示内容如表9所示。
3：在多载波系统中，定义一个泛指的聚合发射功率的功率等级，例如IE：powerClass-v1xxx：{PC0}，PC0不代表具体的功率值，仅代表最大聚合发射功率为各频段上支持的功率等级的功率叠加值。同样，如果终端在某频段上同时上报支持发射分集，则终端在该频段上的功率等级应该减3dB。例如：Band A上报IE：ue-PowerClass PC2并且支持发射分集，Band B上报IE：ue-PowerClass PC2，此时终端应该通过IE：powerClass-v1xxx上报PC0；当Band A上报IE：ue-PowerClass PC2，Band B上报IE：ue-PowerClass PC2，此时终端应该通过IE：powerClass-v1610上报PC1.5。
4：结合3并定义终端在多载波系统中各频段支持的功率等级，如IE：ue-PowerClass-CA-r17：{pc1，pc1.5，pc2，pc3，pc4，pc5}。指示内容如表10所示。
5：在多载波系统中，定义一个终端是否支持最大叠加功率的能力，如IE：sumPowerUL-CA-r17或fullPowerUL-CA-r17：{supported}，如果此IE 缺省，网络则根据现有IE：powerClass-v1530或者powerClass-v1610为终端配置相应的功率，如果终端上报支持sumPowerUL-CA-r17或fullPowerUL-CA-r17，网络则根据各频段上支持的功率等级的最大值为该终端配置相应的功率。如果终端在某频段上同时上报支持发射分集，则终端在该频段上的功率等级应该减3dB。
6：结合5并定义终端在多载波系统中各频段支持的功率等级，如IE：ue-PowerClass-CA-r17：{pc1，pc1.5，pc2，pc3，pc4，pc5}。指示内容如表11所示。
