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：支持蜂窝移动通信的手 机终端等UE，以及基站等。
本公开实施例的一个应用场景为，终端等UE可以上报无线信号的输出功率上报，如采用ue-PowerClass进行UE输出功率上报，上报的输出功率是基于一个频段的，即UE可以上报在一个频段上的输出功率。UE通常以功率等级的方式上报输出功率，功率等级包括PC2和PC3等，其中，PC3表示最大功率为23dBm，PC2表示最大功率为26dBm。当UE在同一个频段上同时进行NR授权频谱业务以及NR直连链路业务时，输出功率上报是基于其授权频谱业务的功率等级进行上报的，并且没有考虑到NR直连链路业务的功率等级。
示例性的：NR Uu接口上的授权频谱业务，其功率等级可以为PC3，也可以是PC2等；同时其NR直连链路业务的功率等级可以是PC3，也可以是PC2(最大26dBm)等，功率等级取决于UE具体的设计以及能力。相关技术中，Uu接口功率等级、PC5接口功率等级和上报的UE功率等级可以出现如表1的情况
表1
Figure PCTCN2021101055-appb-000001
Figure PCTCN2021101055-appb-000002
如上表所示，当同一个频段上同时进行NR授权频谱业务以及NR直连链路业务时，相关技术的功率等级上报方式，无法反应UE实际情况。因此，如何准确地上报UE实际功率等级是亟待解决的问题。
如图2所示，本示例性实施例提供一种信息传输方法，信息传输方法可以应用于蜂窝移动通信系统的UE中，包括：
步骤201：发送功率指示信息，其中，所述功率指示信息，用于指示工作频段内多个接口的UE功率等级。
这里，UE可以是采用蜂窝移动通信技术进行无线通信的手机UE等。接入网设备可以是在蜂窝移动通信系统中，向UE提供接入网接口的基站等。
示例性地，所述功率指示信息，分别指示工作频段内每个接口的UE功率等级；或者，分别指示工作频段内UE将工作的每个接口的UE功率等级。
此处地，UE功率等级可用于供基站确定上行发射功率值或直链链路(SL，SideLink)传输的发射功率等。
UE的上行发射功率的大小可以以功率等级(Power class)进行分级的。例如：功率等级3(PC3)的发射功率是23dBm，功率等级2(PC2)的发射功率是26dBm等。
UE在一个工作频段内可以通过不同的接口实现与对端UE和/或基站的通信。这里，不同接口可以是通过不同通信协议实现的无线通信通道。这里，工作频段可以是部分配置的部分带宽(BWP，Bandwidth Part)。可以 在工作频段上通过多个接口实现与对端UE和/或基站的通信。
在一个实施例中，所述接口，包括：Uu接口和/或直连链路PC5接口。
示例性的，针对V2X通信的一个工作频段，UE可以在一个工作频段内通过Uu接口与基站进行通过，UE还可以在该工作频段内通过直连链路(SL，sidelink)的PC5接口与其他UE进行通信。
相关技术中，UE可以基于工作频段进行UE功率等级的上报，UE上报的是工作频段的UE总功率等级，基站无法根据工作频段的UE总功率等级确定不同接口的功率等级。
这里，UE功率等级可以是UE在每个接口发射信号时采用的功率等级。UE可以上报工作频段内多个接口的UE功率等级。接入网设备基于UE的上报信息，确定多个接口的UE功率等级。
UE可以向基站发送指示多个接口UE功率等级的功率指示信息。这里，可以利用现有的上行信令携带功率指示信息。例如，可以在随机接入的消息3(Msg 3)、媒体存取控制-控制单元(MAC-CE，Media Access Control-Control Element)MAC-CE、无线资源控制(RRC，Radio Resource Control)等信令中携带功率指示信息。功率指示信息也可以由专用上行信令携带。
接入网设备可以基于上行信令中的功率指示信息确定各接口的UE功率等级。接入网设备可以基于各接口的UE功率等级为各接口配置功率参数、资源参数等。减少由于无法确定接口的UE功率等级，产生的功率参数配置错误等问题。
如此，通过UE上报工作频段内多个接口的UE功率等级，基站可以确定每个接口的UE功率等级。提高了基站确定不同接口的UE功率等级的准确性。进而减少由于无法准确确定接口的UE功率等级，产生的UE功率参数配置错误等问题。
在一个实施例中，所述功率指示信息，还用于指示所述工作频段的UE总功率等级。
UE总功率等级可以是UE在工作频段多个接口进行信号发射时的总功率等级。在由于工作频段的UE总功率等级并非多个接口UE功率等级的简单累加，需要考虑到UE的最大发射功率、同频干扰、不同接口传输的时域位置等情况。UE总功率等级可以与多个接口的UE功率等级相同，UE总功率等级可以高于多个接口的UE功率等级。例如，工作频段内两个接口的UE功率等级均为PC3，工作频段的UE总功率等级可以是PC2，也可以是PC3。因此，UE还可以上报工作频段的UE总功率等级。
UE同时在Uu接口和PC5接口上进行通信，由于UE的无线功率放大器最大功率的限制，UE在工作频段UE总功率等级是受限的，例如UE总功率等级为PC2。如果UE同时在Uu接口和PC5接口上采用各自的最大功率进行通信，使得累加的总功率超出UE总功率等级所定义的功率值，UE可以通过将Uu接口的通信和PC5接口的通信分时进行，或者将Uu接口和/或PC5接口的功率回退至更低的等级等方式降低工作频段的总功率，使得同一时间的总功率等于或小于UE总功率等级所定义的功率值。
示例性的，UE上报的功率指示信息可以指示如表2所示的UE功率等级和工作频段的UE总功率等级。
表2
Uu接口UE功率等级 PC5接口UE功率等级 工作频段的UE总功率等级
PC3 PC3 PC3
PC3 PC3 PC2
PC3 PC2 PC2
PC2 PC3 PC2
PC2 PC2 PC2
如此，通过UE上报工作频段内多个接口的UE功率等级以及工作频段 的UE总功率等级，基站可以确定工作频段内每个接口的UE功率等级以及UE总功率等级。如此，通过显性方式指示工作频段内多个接口的UE功率等级，提高基站确定UE功率等级的准确性，进而减少由于无法准确确定功率等级，产生参数配置错误的问题。
在一个实施例中，如图3所示，所述方法还包括：
步骤202：接收基站基于所述功率指示信息发送的配置信息；
步骤203：根据所述配置信息，确定至少一个所述接口的UE功率配置参数。
接入网设备可以基于确定的各接口的UE功率等级和工作频段的UE总功率等级，调整接口的UE功率配置参数。UE功率配置参数可以用于但不限于：调整接口的功率、配置各接口工作的时域等资源等。
通过调整UE功率配置参数可以使UE的功率输出可以满足通信实际需求，并符合通信的规范。
在一个实施例中，所述UE功率配置参数包括至少以下之一：
最高配置功率；
允许的功率回退；
比吸收率SAR调控策略。
基站可以基于实际通信需求，配置各接口的最高发射功率从而得到最高配置功率。例如，可以基于信号质量和/或功耗的需求，为UE配置合适的最高配置功率。
功率回退是指将功率放大器的输入功率从1dB压缩点，即1dB增益点，向后回退预定值，如6～10dB，使得功率放大器保持在线性工作区内工作。基站可以基于各接口的UE功率等级和工作频段的UE总功率等级，配置UE的信号发射功率放大器，使得UE的信号发射功率放大器保持在线性工作区内工作。
SAR是UE设计中衡量UE发射无线信号时对人体辐射量的一个指标。UE的进行信号发射的UE功率等级不能超过SAR的辐射要求。在多个接口同时工作时，在某些事件窗口，例如：多个接口同时以最高功率进行通信时，UE总功率等级可能超出SAR的辐射要求。基站可以基于确定的各接口的UE功率等级和工作频段的UE总功率等级，调整SAR调控策略，如调整各接口的信号发射资源，减少工作频段内总功率过高导致UE辐射超出SAR要求的情况。例如，可以调整各接口的发射时域，使各接口的发射时域不重叠，从而降低工作频段的UE总功率等级。
在一个实施例中，所述方法还包括：
接收基站发送的通信能力上报请求；
响应于所述通信能力上报请求，发送通信能力信息，其中，所述通信能力信息，用于指示所述UE是否能够在所述工作频段采用多个所述接口进行数据传输。
这里，通信能力可以包括但不限于：UE的多接口通信能力。
如图4所示，基站控制UE进行V2X业务过程中，基站和UE进行交互的具体步骤可以包括：
步骤401：基站发送通信能力上报请求要求UE上报授权频谱上同时进行V2X业务的能力。
基站可以在控制UE进行V2X业务之前发送通信能力上报请求。
步骤402：UE上报是否具备授权频谱上同时进行V2X业务的能力。
UE在接收到通信能力上报请求后可以向基站上报通信能力信息，指示在授权频谱上UE可以采用的接口。
示例性的，基站可以在建立控制UE的V2X通信之前发送通信能力上报请求，UE在接收到通信能力上报请求后可以向基站上报通信能力信息，指示UE可以在授权频谱，即工作频段上通过Uu接口和直连链路PC5接口 进行通信。
步骤403：基站根据能力上报以及组网需求配置UE在授权频谱上通过多个接口进行V2X业务。即基站在同一个授权频段内为UE配置Uu接口进行NR通信业务，以及配置PC5接口进行SL通信业务。。
步骤404：UE上报其在该授权频谱上的UE总功率等级ue-PowerClass-IntraConccurent，在PC5接口上的UE功率等级ue-PowerClassPC5，以及Uu接口上的UE功率等级ue-PowerClassUu。可能上报的UE功率等级举例如表2所示。
步骤405：基站根据UE上报的功率等级配置UE响应的功率参数。基站根据UE上报的UE总功率等级，PC5接口上的UE功率等级，Uu接口上的UE功率等级，分别对PC5接口，Uu接口配置相应的最高配置功率、可允许的功率回退、SAR调控策略等指标。
如此，在V2X业务中，UE完成了各接口以及工作频段UE总功率等级上的上报。基站基于上报的UE功率等级完成对接口的功率配置。使得UE的功率输出可以满足通信实际需求，并符合通信的规范。
如图5所示，本示例性实施例提供一种信息传输方法，信息传输方法可以应用于蜂窝移动通信系统的接入网设备中，包括：
步骤501：接收用户设备UE发送的功率指示信息；
步骤502：根据所述功率指示信息，确定工作频段内多个接口的UE功率等级。
这里，UE可以是采用蜂窝移动通信技术进行无线通信的手机UE等。接入网设备可以是在蜂窝移动通信系统中，向UE提供接入网接口的基站等。
示例性地，所述功率指示信息，分别指示工作频段内每个接口的UE功率等级；或者，分别指示工作频段内UE将工作的每个接口的UE功率等 级。
此处地，UE功率等级可用于供基站确定上行发射功率值或直链链路(SL，SideLink)传输的发射功率等。
UE的上行发射功率的大小可以以功率等级(Power class)进行分级的。例如：功率等级3(PC3)的发射功率是23dBm，功率等级2(PC2)的发射功率是26dBm等。
UE在一个工作频段内可以通过不同的接口实现与对端UE和/或基站的通信。这里，不同接口可以是通过不同通信协议实现的无线通信通道。这里，工作频段可以是部分配置的部分带宽(BWP，Bandwidth Part)。可以在工作频段上通过多个接口实现与对端UE和/或基站的通信。
在一个实施例中，所述接口，包括：

示例性的，针对V2X通信的一个工作频段，UE可以在一个工作频段内通过Uu接口与基站进行通过，UE还可以在该工作频段内通过直连链路的PC5接口与其他UE进行通信。
相关技术中，UE可以基于工作频段进行UE功率等级的上报，UE上报的是工作频段的UE总功率等级，基站无法根据工作频段的UE总功率等级确定不同接口的功率等级。
这里，UE功率等级可以是UE在每个接口发射信号时采用的功率等级。UE可以上报工作频段内多个接口的UE功率等级。接入网设备基于UE的上报信息，确定多个接口的UE功率等级。
UE可以向基站发送指示多个接口UE功率等级的功率指示信息。这里，可以利用现有的上行信令携带功率指示信息。例如，可以在随机接入的消息3(Msg 3)、媒体存取控制-控制单元(MAC-CE，Media Access Control-Control Element)MACCE、无线资源控制(RRC，Radio Resource  Control)等信令中携带功率指示信息。功率指示信息也可以由专用上行信令携带。
接入网设备可以基于上行信令中的功率指示信息确定各接口的UE功率等级。接入网设备可以基于各接口的UE功率等级为各接口配置功率参数、资源参数等。减少由于无法确定接口的UE功率等级，产生的功率参数配置错误等问题。
如此，通过UE上报工作频段内多个接口的UE功率等级，基站可以确定每个接口的UE功率等级。提高了基站确定不同接口的UE功率等级的准确性。进而减少由于无法准确确定接口的UE功率等级，产生的UE功率参数配置错误等问题。
在一个实施例中，所述方法还包括：
根据所述功率指示信息，确定所述工作频段的UE总功率等级。
UE总功率等级可以是UE在工作频段多个接口进行信号发射时的总功率等级。由于工作频段的UE总功率等级并非多个接口UE功率等级的简单累加，需要考虑到UE的最大发射功率、同频干扰、不同接口传输的时域位置等情况。UE总功率等级可以与多个接口的UE功率等级相同，UE总功率等级可以高于多个接口的UE功率等级。例如，工作频段内两个接口的UE功率等级均为PC3，工作频段的UE总功率等级可以是PC2，也可以是PC3。因此，UE还可以上报工作频段的UE总功率等级。
UE同时在Uu接口和PC5接口上进行通信，由于UE的无线功率放大器最大功率的限制，UE在工作频段UE总功率等级是受限的，例如UE总功率等级为PC2。如果UE同时在Uu接口和PC5接口上采用各自的最大功率进行通信，使得累加的总功率超出UE总功率等级所定义的功率值，UE可以通过将Uu接口的通信和PC5接口的通信分时进行，或者将Uu接口和/或PC5接口的功率回退至更低的等级等方式降低工作频段的总功率，使得 同一时间的总功率等于或小于UE总功率等级所定义的功率值。
示例性的，UE上报的功率指示信息可以指示如表2所示的UE功率等级和工作频段的UE总功率等级。
如此，通过UE上报工作频段内多个接口的UE功率等级以及工作频段的UE总功率等级，基站可以确定工作频段内每个接口的UE功率等级以及UE总功率等级。如此，通过显性方式指示工作频段内多个接口的UE功率等级，提高基站确定UE功率等级的准确性，进而减少由于无法准确确定功率等级，产生参数配置错误的问题。

接入网设备可以基于确定的各接口的UE功率等级和工作频段的UE总功率等级，调整接口的UE功率配置参数。UE功率配置参数可以用于但不限于：调整接口的功率、配置各接口工作的时域等资源等。
通过调整UE功率配置参数可以使UE的功率输出可以满足通信实际需求，并符合通信的规范。
在一个实施例中，所述UE功率配置参数包括至少以下之一：
最高配置功率；
允许的功率回退；
比吸收率SAR调控策略。
基站可以基于实际通信需求，配置各接口的最高发射功率从而得到最高配置功率。例如，可以基于信号质量和/或功耗的需求，为UE配置合适的最高配置功率。
