具体实施方式
现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的范例；相反，提供这些实施方式使得本申请将更加全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。所描述的特征、结构或特性可以以任何合适的方式结合在一个或更多实施方式中。在下面的描述中，提供许多具体细节从而给出对本申请的实施方式的充分理解。然而，本领域技术人员将意识到，可以实践本申请的技术方案而省略所述特定细节中的一个或更多，或者可以采用其它的方法、组元、装置、步骤等。在其它情况下，不详细示出或描述公知技术方案以避免喧宾夺主而使得本申请的各方面变得模糊。
此外，附图仅为本申请的示意性图解，并非一定是按比例绘制。图中相同的附图标记表示相同或类似的部分，因而将省略对它们的重复描述。附图中所示的一些方框图是功能实体，不一定必须与物理或逻辑上独立的实体相对应。可以采用软件形式来实现这些功能实体，或在一个或多个硬件模块或集成电路中实现这些功能实体，或在不同网络和/或处理器装置和/或微控制器装置中实现这些功能实体。
发明人发现：终端只上报载波聚合场景中总的功率等级，并不能代表载波聚合中各载波的最大发射功率，这样容易导致基站记录的载波聚合中各载波的最大发射功率等级有误。
图1示出了可以应用本申请实施例的一种基于载波聚合的信息上报方法及基于载波聚合的信息上报装置的示例性应用环境的系统架构的示意图。
如图1所示，系统架构100可以包括终端设备101、102、103中的一个或多个，网络104和服务器105。网络104用以在终端设备101、102、103和服务器105之间提供通信链路的介质。网络104可以包括各种连接类型，例如有线、无线通信链路或者光纤电缆等等。终端设备101、102、103可以是具有显示屏的各种电子设备，包括但不限于台式计算机、便携式计算机、智能手机和平板电脑等等。应该理解，图1中的终端设备、网络和服务器的数目仅仅是示意性的。根据实现需要，可以具有任意数目的终端设备、网络和服务器。比如服务器105可以是多个服务器组成的服务器集群等。
本申请实施例所提供的基于载波聚合的信息上报方法一般由服务器105执行，相应地，基于载波聚合的信息上报装置一般设置于服务器105中。但本领域技术人员容易理解的是，本申请实施例所提供的基于载波聚合的信息上报方法也可以由终端设备 101、102或103执行，相应的，基于载波聚合的信息上报装置也可以设置于终端设备101、102或103中，本示例性实施例中对此不做特殊限定。举例而言，在一种示例性实施例中，服务器105可以确定所述载波聚合场景中的各载波分别作为单载波时的第一最大发射功率；确定所述各载波分别在所述载波聚合场景中的第二最大发射功率；若检测到所述载波聚合场景中存在第一最大发射功率大于第二最大发射功率的目标载波，则向基站上报所述目标载波的第二最大发射功率对应的功率等级。
图2示出了适于用来实现本申请实施例的电子设备的计算机系统的结构示意图。
需要说明的是，图2示出的电子设备的计算机系统200仅是一个示例，不应对本申请实施例的功能和使用范围带来任何限制。
如图2所示，计算机系统200包括中央处理单元(CPU)201，其可以根据存储在只读存储器(ROM)202中的程序或者从储存部分208加载到随机访问存储器(RAM)203中的程序而执行各种适当的动作和处理。在RAM 203中，还存储有系统操作所需的各种程序和数据。CPU 201、ROM 202以及RAM 203通过总线204彼此相连。输入/输出(I/O)接口205也连接至总线204。
以下部件连接至I/O接口205：包括键盘、鼠标等的输入部分206；包括诸如阴极射线管(CRT)、液晶显示器(LCD)等以及扬声器等的输出部分207；包括硬盘等的储存部分208；以及包括诸如LAN卡、调制解调器等的网络接口卡的通信部分209。通信部分209经由诸如因特网的网络执行通信处理。驱动器210也根据需要连接至I/O接口205。可拆卸介质211，诸如磁盘、光盘、磁光盘、半导体存储器等等，根据需要安装在驱动器210上，以便于从其上读出的计算机程序根据需要被安装入储存部分208。
特别地，根据本申请的实施例，下文参考流程图描述的过程可以被实现为计算机软件程序。例如，本申请的实施例包括一种计算机程序产品，其包括承载在计算机可读介质上的计算机程序，该计算机程序包含用于执行流程图所示的方法的程序代码。在这样的实施例中，该计算机程序可以通过通信部分209从网络上被下载和安装，和/或从可拆卸介质211被安装。在该计算机程序被中央处理单元(CPU)201执行时，执行本申请的方法和装置中限定的各种功能。
本示例实施方式提供了一种基于载波聚合的信息上报方法。该基于载波聚合的信息上报方法可以应用于上述服务器105，也可以应用于上述终端设备101、102、103中的一个或多个，本示例性实施例中对此不做特殊限定。参考图3所示，该基于载波 聚合的信息上报方法可以包括以下步骤S310至步骤S330。
步骤S310：确定载波聚合场景中的各载波分别作为单载波时的第一最大发射功率。
步骤S320：确定各载波分别在载波聚合场景中的第二最大发射功率。
步骤S330：若检测到载波聚合场景中存在第一最大发射功率大于第二最大发射功率的目标载波，则向基站上报目标载波的第二最大发射功率对应的功率等级。载波聚合场景中存在第一最大发射功率大于第二最大发射功率的目标载波，即所述各个载波中存在第一最大发射功率大于第二最大发射功率的目标载波。
可见，实施图3所示的方法，针对载波聚合场景中每个载波，可以在该载波作为单载波时的最大发射功率大于在载波聚合场景中的最大发射功率时，及时向基站上报载波聚合场景中该载波的实际最大发射功率等级，以保证基站中存储的各载波最大发射功率等级与终端中各载波的实际最大发射功率等级之间存在一致性，这样可以有利于进行更有效的信息传输。
下面，对于本示例实施方式的上述步骤进行更加详细的说明。
在步骤S310中，确定载波聚合场景中的各载波分别作为单载波时的第一最大发射功率。其中，载波聚合(CA)，是将多个不同/相同频率的载波聚合成一个更宽的频谱，同时也可以把不连续的频谱碎片聚合在一起，从而达到提高带宽的效果。此外，上述的载波也可以表示为频段。载波聚合场景下，各载波之间的关系为：频段内连续、频段内不连续或频段间不连续。此外，第一最大发射功率可以表征单载波收发数据时能够使用的最大的发射功率，若终端设备对应于多个单载波，那么，每个单载波可以对应于一个第一最大发射功率。
在步骤S320中，确定各载波分别在载波聚合场景中的第二最大发射功率。其中，第二最大发射功率可以表征载波聚合中各载波收发数据时能够使用的最大的发射功率。
在一些实施例中，上述方法还包括：当接收到载波分配指令时，重新分配各载波对应的发射通道，以使得发射通道与各载波之间的关系为一一对应；对各载波进行载波聚合，并判定各载波处于载波聚合场景中。
载波分配指令可以用于指示终端设备对各载波能够使用的发射通道进行重新分配，终端设备对应的发射通道可以为一个或多个，本申请实施例不作限定。当终端设备对应的发射通道为多个时，在载波聚合场景下，一个载波对应一个发射通道，在单载波场景下，一个载波可以对应一个或多个发射通道，在单载波场景下，终端设备可 以对应于一个或多个载波。
可见，实施上述可选的实施例，能够实现对于多个载波的聚合，达到提高带宽的效果。
在载波聚合之前，终端设备中的载波可以通过多通道进行数据传输，具体请参阅图4，图4示意性示出了根据本申请的一些实施例的单载波场景示意图。如图4所示，在单载波场景下，终端设备包含作为单载波的频段x，频段x可以同时使用终端设备中的通道1和通道2收发信号，通道1和通道2分别对应的最大发射功率分别为23dBm，通过通道1和通道2的最大发射功率叠加，可以使得频段x作为单载波时的第一最大发射功率为26dBm。
在载波聚合之后，终端设备中的多个载波可以分别通过各自对应的通道进行数据传输，具体请参阅图5，图5示意性示出了根据本申请的一些实施例的载波聚合场景示意图。如图5所示，在载波聚合场景下，终端设备包含载波聚合的频段x和频段y，基于终端设备对于通道的重新分配，频段x和频段y分别对应于通道1和通道2，那么，频段x和频段y分别对应的第二最大发射功率为23dBm。
举例来说，终端设备对应于载波x和载波y，载波x和载波y作为单载波时的最大发射功率可以为23dBm也可以为26dBm，但是，虽然载波聚合后的最大发射功率可以达到26dBm，但是载波聚合中的载波x和载波y通过各自对应的通道进行信息传输时不一定都达到26dBm，也就是说，当载波聚合后的最大发射功率为26dBm时，载波x和载波y对应的最大发射功率可以为以下情况：[23dBm，23dBm]、[23dBm，26dBm]、[26dBm，23dBm]、[26dBm，26dBm]。对于上述举例，还可以通过下述表格进行表示：
Figure PCTCN2022104847-appb-000001
在步骤S330中，若检测到载波聚合场景中存在第一最大发射功率大于第二最大发射功率的目标载波，则向基站上报目标载波的第二最大发射功率对应的功率等级。
基站可以为3G基站、4G基站、5G基站、6G基站中至少一种，本申请实施例不作限定。此外，目标载波的数量可以为一个或多个。此外，功率等级可以用于表征终端设备(如，用户设备(User Equipment，UE))的信息收发能力，终端设备的能力信息中包含功率等级。具体地，终端设备的能力信息可以包括指示终端设备所支持的无线电接入技术的信息，例如，由终端设备所支持的功率等级、频带、载波聚合(CA)频带组合、双工模式、业务简档、无线电承载等。其中，双工模式包括时分双工(Time Division Duplexing，TDD)和频分双工(Frequency Division Duplexing，FDD)，TDD的收发信息共用一个射频频点，上行链路和下行链路使用不同的时隙进行通信，FDD的收发信息使用不同的射频频点进行通信。本申请中的终端设备可以应用上述的TDD模式。
在一些实施例中，向基站上报目标载波的第二最大发射功率对应的功率等级，包括：生成包含载波标识字段和功率等级字段的第一指示信息；其中，载波标识字段至少用于指示目标载波对应的标识，功率等级字段至少用于指示目标载波的第二最大发射功率对应的功率等级；向基站发送第一指示信息。
载波标识字段可以表示为CA-BandNR，功率等级字段可以表示为PowerClass，功率等级字段可以指示载波聚合场景中的各载波作为单载波时对应的功率等级是否适用于载波聚合场景。此外，第一指示信息可以由终端设备中的终端能力信息单元(UE capability information elements)生成。
举例来说，第一指示信息可以表示如下：
Figure PCTCN2022104847-appb-000002
需要说明的是，上述参数可以应用于4G和5G双连接的相互兼容场景下。
可见，实施上述可选的实施例，能够为基站提供准确的指示信息，以使得基站基于该指示信息精准调整载波功率等级。
在一些实施例中，向基站发送第一指示信息之后，基站将目标载波的第一最大发射功率对应的功率等级，更新为目标载波的第二最大发射功率对应的功率等级。
基站可以用于存储接入的各终端设备中每个载波的第一最大发射功率等级。举例来说，第一最大发射功率对应的功率等级可以表示为(Power Class 2，+26dBm)，即，功率等级为2；第二最大发射功率对应的功率等级可以表示为(Power Class 3，+23dBm)即，功率等级为3。
可见，实施上述可选的实施例，能够实现对于功率等级的准确调校。
在一些实施例中，若检测到各载波中不存在第一最大发射功率大于第二最大发射功率的目标载波，则上报包含载波标识字段的第二指示信息；向基站发送第二指示信息，以使得基站在检测到第二指示信息存在缺省字段时，判定不存在功率等级更新指示。
缺省字段可以理解为第二指示信息中不包含载波标识字段或功率等级字段。第二指示信息的发送方式与第一指示信息的发送方式一致。
可见，实施上述可选的实施例，能够在不需要进行功率等级调校时，向基站发送准确的指示信息。
在一些实施例中，向基站上报目标载波的第二最大发射功率对应的功率等级，包括：确定终端设备所属的至少一个小区，确定至少一个小区中每个小区对应的基站；向至少一个小区中每个小区对应基站上报目标载波的第二最大发射功率对应的功率等级。
若终端设备所属的存在多个小区，各小区的覆盖能力可以相同也可以不同，多个小区之间可以存在重叠覆盖区域。终端设备所属的小区可以表征基站的覆盖范围。
可见，实施上述可选的实施例，能够保证对于终端设备所属的小区的功率等级上报及时性。
在一些实施例中，当切换至载波聚合场景之后，当存在上行数据时，通过目标载波以小于或等于目标载波的第二最大发射功率的发射功率向基站上传上行数据。其中，上行数据可以为终端设备需要发送至基站的数据。
可见，实施上述可选的实施例，能够提升基站对终端设备功率调整的准确性。
此外，在一些实施例中，整合图3所示的各步骤及其实施例，展示为图6所示的基于载波聚合的信息上报方法，具体包括：步骤S610～步骤S680。
步骤S610：当接收到载波分配指令时，终端设备重新分配各载波对应的发射通道， 以使得发射通道与各载波之间的关系为一一对应，对各载波进行载波聚合，并判定各载波处于载波聚合场景中。
步骤S620：终端设备确定载波聚合场景中的各载波分别作为单载波时的第一最大发射功率。
步骤S630：终端设备确定各载波分别在载波聚合场景中的第二最大发射功率。若检测到载波聚合场景中存在第一最大发射功率大于第二最大发射功率的目标载波，则执行步骤S640。若检测到载波聚合场景中不存在第一最大发射功率大于第二最大发射功率的目标载波，则执行步骤S650。
步骤S640：终端设备生成包含载波标识字段和功率等级字段的第一指示信息；其中，载波标识字段至少用于指示目标载波对应的标识，功率等级字段至少用于指示目标载波的第二最大发射功率对应的功率等级。
步骤S650：终端设备生成包含载波标识字段的第二指示信息，并向基站发送第二指示信息，以使得基站在检测到第二指示信息存在缺省字段时，判定不存在功率等级更新指示。进而，结束流程。
步骤S660：终端设备确定终端设备所属的至少一个小区，确定至少一个小区中每个小区对应的基站；向至少一个小区中每个小区对应的基站发送第一指示信息。
步骤S670：基站将目标载波的第一最大发射功率对应的功率等级，更新为目标载波的第二最大发射功率对应的功率等级。
步骤S680：当存在上行数据时，终端设备以小于或等于目标载波的第二最大发射功率的发射功率向基站上传上行数据。
需要说明的是，步骤S610～步骤S680与图3所示的各步骤及其实施例相对应，针对的步骤S610～步骤S680具体实施方式，请参阅图3所示的各步骤及其实施例，此处不再赘述。
