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。
在图1所示的通信系统100中，网络设备120可以是与终端设备110通信的接入网设备。接入网设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备110(例如UE)进行通信。
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3GPP标准中，可基于功率等级(Power Class,PC)定义终端设备的发射功率，即终端设备的最大发射功率不能超过终端设备的功率等级对应的发射功率上限值，功率等级对应的发射功率也可称为最大发射功率标称值，功率等级对应的发射功率上限值等于功率等级对应的发射功率与最高容限的和。每个功率等级可对应不同的发射功率。此外，考虑到终端在实现中功率控制的不确定度，定义了最大发射功率标称值的容限(Tolerance)范围。容限范围可包括最低容限和最高容限。对于不同频段可能会不同的容限范围，下面结合表1进行说明。
表1
Figure PCTCN2021070714-appb-000001
如表1所示，功率等级1(PC1)对应的发射功率为31分贝毫瓦(dBm)，对于n14频段，PC1对应的发射功率的容限范围为+2/-3dB，也即只要终端的发射功率处于28～33dBm的范围内即可用认为该终端满足了PC1。相应的，对于功率等级2(PC2)，终端的发射功率是26dBm，对于n40频段，PC2对应的发射功率的容限范围为+2/-3dB，也即终端设备的最大发射功率的范围是23～28dBm。对于功率等级(PC3)，PC3对应的发射功率是23dBm，对于n1频段，PC3对应的发射功率的容限范围为+2/-2dB，也即终端设备的最大发射功率的范围是21～25dBm。
需要说明的是，在本申请实施例的描述中，术语“对应”可表示两者(例如功率等级和发射功率)之间具有直接对应或间接对应的关系，也可以表示两者(例如功率等级和发射功率)之间具有关联关系，也可以是指示与被指示、配置与被配置等关系。
终端在进行发射功率控制时，将按照可配置最大发射功率(P CMAX,f,c)进行计算，并控制其发射功率的大小。
下面以单载波为例，结合表2进行说明。
表2
Figure PCTCN2021070714-appb-000002
如表2所示，P CMAX,f,c的下限为P CMAX_L,f,c，也即最大发射功率需要高于这个下限。P CMAX,f,c的上限为P CMAX_H,f,c，也即最大发射功率需要低于这个上限。从下面的公式可以看出，P CMAX_H,f,c实际是取了P EMAX,c和P PowerClass–ΔP PowerClass中的最小值。P EMAX,c是基站配置的小区内允许的终端最大发射功率，P PowerClass–ΔP PowerClass定义了功率等级带来的限制条件，通常情况下，ΔP PowerClass取值为0，因此主要受到P PowerClass的取值限制。P PowerClass对应的是功率等级对应的发射功率，即不考虑容限时的取值，也即，对于PC1是31dBm，对于PC2是26dBm，对于PC3是23dBm。从这里可以看到终端的发射功率将不会超过功率等级对应的发射功率上限值。
在NR中除了单频段外，也定义了频段组合下的功率等级，比如对于CA、DC、EN-DC、NE-DC等都分别定义了各个频段组合的功率等级。
下面是UL CA的功率等级为例进行说明。
表3

如表3所示，频段组合下的功率等级跟单频段的功率等级定义类似，也包括了最大发射功率标称 值和容限范围。不同于单频段的地方在于这里包括了多个频段，这多个频段的总发射功率受到功率等级(包括容限范围)的约束，其中在最大可配置发射功率P CMAX,f,c公式中最大发功率的上限定义为：
P CMAX_H＝MIN{10log 10∑p EMAX,c，P EMAX,CA，P PowerClass}。
其中，P PowerClass对应的是功率等级对应的发射功率，即不考虑容限时的取值。需要说明的是，通常情况下，频段组合的功率等级对应的发射功率是个定值，只不过对于频段组合下的功率等级是相对频段组合的总功率来而言的。例如，对于PC1是31dBm，对于PC2是26dBm，对于PC3是23dBm。从这里可以看到终端即使在频段组合下其发射功率也将不会超过基于功率等级对应的发射功率上限值。
通过以上分析可见，不管针对单频段下的功率等级还是针对频段组合下的功率等级，终端的最大发射功率都受到功率等级对应的发射功率上限值的约束，即终端的最大发射功率有一个上限值，在实际中，终端的最大发射功率时不能超过该上限值。
对于功率等级，3GPP只定义功率等级对应的发射功率以及功率等级对应的发射功率的容限范围，功率等级对应的发射功率的容限范围可包括功率等级对应的发射功率的最低容限和最高容限，而对具体的实现方式不做约束。基于此，即使终端设备的功率放大器(Power Amplifier，PA)的发射能力超出功率等级对应的发射功率上限值，在实际中，仍然需要控制终端设备的最大发射功率不能超过功率等级对应的发射功率上限值，进而对具备更高发射能力的终端设备的发射功率造成了浪费，限制了其功率放大器的发射能力的使用。
图2和图3是本申请实施例提供的射频框架的示意性结构图。
如图2所示，针对单频段，以PC2为例，假设终端有两个发射支路(如支持上行MIMO、发射分集、EN-DC、NE-DC、上行CA等的终端)，在硬件实现中，可以采用如图2中的几种方式实现，即，可以采用两个PC3的功率放大器(Power Amplifier,PA)来实现，也可以采用一个PC2的PA和一个PC3的PA来实现，还可以采用两个PC2的PA来实现。但不论采用哪种实现方式，如上面所述，其最大发射功率是不能够超出功率等级对应的发射功率上限值。
如图3所示，针对频段组合nx+ny，以PC2为例，在硬件实现中，可以采用频段nx和频段ny的分别对应的PA实现，例如，可以采用如图3中的几种方式实现，即，可以采用两个PC3的功率放大器(Power Amplifier,PA)来实现，也可以采用一个PC2的PA和一个PC3的PA来实现，还可以采用两个PC2的PA来实现。但不论采用哪种实现方式，如上面所述，其总的最大发射功率是不能够超出功率等级对应的发射功率上限值。
在图2和图3所示的射频架构中，尽管方式2和方式3采用了相比方式1发射功率能力更高的PC2PA，但受到PC2对应的发射功率上限值的影响，在实际进行最大发射功率的功率控制时仍然不能超过PC2对应的发射功率上限值。即，终端的最大发射功率受到功率等级对应的发射功率上限值的约束，由此，会导致即使终端具备发射更高功率的能力也无法突破该功率等级对应的发射功率上限值，导致其发射功率能力的浪费，也无法达到最优的性能。
当然，图2和图3仅为本申请的示例，不应理解为对本申请的限制。
例如，针对单频段，终端在单个频段上发射功率通常包括了单PA发射、双PA发射两种情况。在图2介绍了双PA发射的情况，也即当一个PC2终端包含了PC2的PA时，其发射功率能力实际是可以超过PC2对应的发射功率上限值。类似的情况实际也存在于单PA发射，因为通常PA的发射能力是会超过功率等级对应的发射功率上限值，用于弥补PA后面所连接器件的功率损耗，而受限于功率等级对应的发射功率上限值，使得单PA情况下终端的最大发射功率也会受限。因此，不论是单PA发射还是双PA发射，其最大发射功率都受到了功率等级上限的限制，而不能达到最优的性能。
本申请实施例提供一种无线通信方法、终端设备和网络设备，能够降低具备更高发射能力的终端设备的发射功率的浪费，提升了其功率放大器的发射能力的使用效率。
图4是本申请实施例提供的无线通信方法200的示意性流程图。所述方法200可通过终端设备和网络设备交互执行，例如所述方法200可通过如图1所示的终端设备110和如图1所示的网络设备120交互执行。
如图4所示，所述方法200可包括：
S210，终端设备向网络设备发送指示信息，所述指示信息用于确定所述终端设备的最大发射功率。
换言之，网络设备接收终端设备发送的指示信息，所述指示信息用于确定所述终端设备的最大发射功率。可选地，在本申请实施例中，指示信息包括物理层信令例如下行控制信息(Downlink Control Information，DCI)、系统消息(System Information，SI)、无线资源控制(Radio Resource Control，RRC)信令和媒体接入控制控制单元(Media Access Control Control Element，MAC CE)中的至少一种。
基于以上技术方案，终端设备向网络设备发送用于确定所述终端设备的最大发射功率的信息，能够支持终端设备自主确定最大发射功率，并且保证网络设备能够知道终端设备的最大发射功率，能够降低具备更高发射能力的终端设备的发射功率的浪费，提升了其功率放大器的发射能力的使用效率。
需要说明的是，在本申请的实施例中提到的“指示信息”可以是直接指示信息，也可以是间接指示信息，还可以是表示具有关联关系的信息。举例说明，A指示B，可以表示A直接指示B，例如B可以通过A获取；也可以表示A间接指示B，例如A指示C，B可以通过C获取；还可以表示A和B之间具有关联关系。
在本申请的一些实施例中，所述终端设备的功率等级对应的发射功率仅用于定义所述最大发射功率的下限。
换言之，不基于功率等级对应的发射功率上限值对终端设备的最大发射功率进行约束，即仅基于功率等级对应的下限值对终端设备的最大发射功率进行约束。或者说，可以通过解除功率等级对应的发射功率上限值的限制来实现对于有更高发射功率能力的终端可以实现更高的功率发射。本申请实施例对终端的功率等级的定义进行了调整，仅定义了功率等级对应的发射功率下限值，也即终端的最大发射功率只需要超过功率等级对应的发射功率下限值即可。下面结合表4进行说明。
表4
Figure PCTCN2021070714-appb-000004
如表4所示，功率等级1对应的发射功率仍然为31dBm，最低容限为-3dB(这里仅仅是示例，容限值可以为其他值如-2或-2.5等)，也即终端的最大发射功率能力至少需要达到28dBm；功率等级1.5对应的发射功率仍然为29dBm，最低容限为-3dB(这里仅仅是示例，容限值可以为其他值如-2或-2.5等)，也即终端的最大发射功率能力至少需要达到26dBm；功率等级2对应的发射功率仍然为26dBm，最低容限为-3dB(这里仅仅是示例，容限值可以为其他值如-2或-2.5等)，也即终端的最大发射功率能力至少需要达到23dBm；功率等级3对应的发射功率仍然为23dBm，最低容限为-3dB(这里仅仅是示例，容限值可以为其他值如-2或-2.5等)，也即终端的最大发射功率能力至少需要达到20dBm。
简言之，针对功率等级，仅定义了最大发射功率需要达到的下限值，而不对上限值进行定义。
在仅仅定义了最大发射功率需要达到的下限值，而不对上限值进行定义的情况下，相当于，终端设备的最大发射功率没有上限约束，一方面，可以提升终端设备的最大发射功率的自由度，以保证终端设备能够达到最优的性能。另一方面，通过指示信息可以使得网络设备知道终端设备实际的最大发射功率，以保证正常通信。
在本申请的一些实施例中，所述指示信息包括用于指示所述最大发射功率的信息，所述终端设备的功率等级对应多个发射功率包括所述最大发射功率。
换言之，通过修改功率等级的定义，去掉功率等级中针对最大发射功率的上限的固定约束，并直接定义可选的多个上限(即多个发射功率)，并由终端上报其能达到的上限(即最大发射功率)。例如，针对PC2，可定义多个可选的多个发射功率，如27dBm,28dBm,29dBm等，终端通过指示信息来告知网络设备最大发射功率，如28dBm。
在本申请的一些实施例中，所述指示信息包括用于指示第一最高容限的信息，所述最大发射功率等于所述终端设备的功率等级对应的发射功率和所述第一最高容限的和，针对所述终端设备的功率等级对应的发射功率定义有多个最高容限，所述多个最高容限包括所述第一最高容限。
换言之，通过修改功率等级的定义，将功率等级中针对最大发射功率的上限的固定约束，修改为针对最大发射功率的可选的多个上限(即多个最高容限)，并由终端上报其能达到的上限(即第一最高容限)。例如，针对PC2，可定义多个可选的多个最高容限，如+2dB，+3dB,+4dB等，终端通过指示信息来告知网络设备最大发射功率采用的所述多个最高容限中的第一最高容限，如+3dB。
在本申请的一些实施例中，所述指示信息包括用于指示所述终端设备的第一射频架构的信息，所述最大发射功率是根据所述第一射频架构对应的信息确定的。
以PC2为例，所述第一射频架构可以是如图2所示方式1至方式3中的任一种架构，也可以是如图3所示方式1至方式3中的任一种架构。结合图3来说，通过每个PA的功率等级代表其发射功率能力，终端的双发架构可以为PC3+PC3，PC2+PC3以及PC2+PC2，终端设备可向网络设备指示所述终端设备的双发架构。
可选的，所述第一射频架构对应的信息为第二最高容限，所述最大发射功率等于所述功率等级对应的发射功率和所述第二最高容限的和。
换言之，不同的架构可对应不同的最高容限。
可选的，所述第一射频架构对应的信息为第一发射功率，所述最大发射功率等于所述第一发射功率。
换言之，不同的架构可对应不同的发射功率。
下面结合表5以不同的架构对应不同的发射功率为例进行说明。
表5
双发架构 PC3+PC3 PC2+PC3 PC2+PC2
发射功率 26dBm 28dBm 29dBm
如表5所示，PC3+PC3对应的发射功率为26dBm，PC2+PC3对应的发射功率为28dBm，以及PC2+PC2对应的发射功率为29dBm。
在本申请的一些实施例中，所述指示信息包括用于指示增强发射功率的信息，所述最大发射功率等于所述终端设备的功率等级对应的发射功率以及所述增强发射功率的和。
换言之，对功率等级的定义不作改动的情况下，引入增强发射功率。所述增强发射功率旨在量化额外增加的发射功率。所述增强发射功率为相对功率等级对应的发射功率上限额外增加的发射功率。所述增强发射功率用于扩展终端设备的功率等级能力。
下面以NR频段nx的PC2为例，对增强发射功率进行说明。
表6
NR频带 功率等级2(dBm) 容限范围(dB)
nx 26dBm +2/-3
如表6所示，针对NR频段nx，功率等级2对应的发射功率为26dBm，容限范围为+2/-3。通过引用增强发射功率，可以扩展该功率等级对应的发射功率上限，比如1dB增强、2dB增强、3dB增强等，相应的，终端的最大发射功率为27dBm、28dBm、29dBm，由终端设备去指示其最大发射功率的实际能力，可以指示增强的值，例如1dB/2dB/3dB等，也可以指示增强后的最大发射功率，例如27dBm/28dBm/29dBm。网络设备获取到该指示信息后结合功率等级的定义可以得到终端的实际的最大发射功率。
当然，所述指示信息包括用于指示增强发射功率的信息的情况下，若所述终端设备的功率等级对应的发射功率定义有一个最高容限，所述最大发射功率也可以等于所述终端设备的功率等级对应的发射功率、所述一个最高容限以及增强发射功率的和。
在本申请的一些实施例中，所述终端设备的功率等级为单频段下的功率等级。
在本申请的一些实施例中，所述终端设备的功率等级为频段组合下的功率等级，所述终端设备的功率等级对应的发射功率为所述频段组合中的各个的频段的发射功率的和。
换言之，终端设备的功率等级对应的发射功率是各个频段的功率和。即可以理解为频段组合的功率等级对应的发射功率。这种情况下，上述单频段下的最大发射功率的扩展方法同样适用于频段组合，只不过区别地方在于功率的扩展在频段组合下是指的多个频段的总发射功率。
在本申请的一些实施例中，所述最大发射功率等于频段组合中的各个的频段下的功率等级所对应的发射功率的和。
换言之，对于频段组合下的功率等级，由于其包含了多频段，且每个频段也会分别上报其功率等级。在一种可能的实现方式中，最大发射功率的扩展方式是去掉频段组合的功率等级上限，而采用终端在各个频段功率等级对应的发射功率的和作为该频段组合下的最大发射功率。
下面以频段组合nx+ny为例进行说明。假设终端在频段nx的功率等级为PC2，且其对应的发射功率为M dBm；频段ny的功率等级为PC3，且其对应的发射功率为N dBm；终端在频段组合nx+ny上的功率等级为PC2，则最大发射功率的下限依然遵循PC2的定义，即其最大发射功率仍然受到功率等级对应的发射功率下限的约束，而最大发射功率为M+N dBm。体现在终端可配置的最大发射功率Pcmax定义上可以为以下两种方式：
方式1：
P CMAX_H＝MIN{10log 10∑p EMAX,c,P EMAX,CA}。
即，直接从P CMAX_H中去掉P PowerClass，并定义终端在该频段组合下的最大发射功率为M+N dBm。
方式2：
P CMAX_H＝MIN{10log 10∑p EMAX,c,P EMAX,CA,P PowerClass}。
即，保留P CMAX_H中的P PowerClass，但对其含义进行重新定义，也即，P PowerClass从表示该频段组合的功率等级对应的发射功率(不考虑容限范围时的取值，即PC1是31dBm，PC2是26dBm，PC3是23dBm)，变更为终端在该频段组合中各频段功率等级对应的发射功率(不考虑容限范围时的取值， PC1是31dBm，PC2是26dBm，PC3是23dBm)的和。
本申请实施例中，通过解除功率等级对应的发射功率上限值，来使得终端可以最大化其发射功率能力，另外，通过引入指示信息使得终端设备告知基站其最大发射功率，或在频段组合下采用单频段下的功率等级对应的发射功率的和作为实际的最大发射功率，能够降低具备更高发射能力的终端设备的发射功率的浪费，提升了其功率放大器的发射能力的使用效率。
