具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、免授权频谱上的LTE (LTE-based access to unlicensed spectrum，LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信(5th-Generation，5G)系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
可选地，本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以应用于独立(Standalone，SA)布网场景。
本申请实施例对应用的频谱并不限定。例如，本申请实施例可以应用于授权频谱，也可以应用于免授权频谱。
本申请实施例结合网络设备和终端设备描述了各个实施例，其中：终端设备也可以称为用户设备(User Equipment，UE)、接入终端、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等。终端设备可以是WLAN中的站点(STAION，ST)，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)设备、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、可穿戴设备以及下一代通信系统，例如，NR网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端设备等。
作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
网络设备可以是用于与移动设备通信的设备，网络设备可以是WLAN中的接入点(Access Point，AP)，GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB，NB)，还可以是LTE中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及NR网络中的网络设备(gNB)或者未来演进的PLMN网络中的网络设备等。
在本申请实施例中，网络设备为小区提供服务，终端设备通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备进行通信，该小区可以是网络设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(Small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
图1示例性地示出了一种通信系统100。该通信系统包括一个网络设备110和两个终端设备120。可选地，该通信系统100可以包括多个网络设备110，并且每个网络设备110的覆盖范围内可以包括其它数量的终端设备120，本申请实施例对此不做限定。
可选地，该通信系统100还可以包括移动性管理实体(Mobility Management Entity，MME)、接入与移动性管理功能(Access and Mobility Management Function，AMF)等其他网络实体，本申请实施例对此不作限定。
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。
如图2所示，为多载波通信的一种示例。在4G终端多载波工作方式中，载波1和载波2可以是相同频段也可以是不同频段。在5G NR系统中，工作于毫米波频段的终端，一般会采用多个天线阵子组成的天线阵形成窄波束来发射和接收信号。而且这些窄波束实际会具有比较强的指向性，如图3所示，5G终端在毫米波频段基于波束通信方式。此时，如有另外一个不共站址的基站2为该终端配置了另外一个载波，那么终端可能无法在该载波上收发信号，进而导致载波配置失败。
此外，毫米波频段间的频率差距非常大。例如图4的5G毫米波频段。这可能导致不同频段或同一频段内不同载波间的空间传播损耗差别很大。并且可能导致不同频率的载波在接收端的信号功率谱密度差别很大。例如，图5的5G毫米波频段功率谱密度。以下行信号为例，假设发射端的信号具有相同的强度，在UE侧接收到的信号强度实际会差别很大(如20dB以上)。这时，终端内部的低噪声放大器(Low Noise Amplification，LNA)在同时放大两个接收信号时，会面临强信号对弱信号的干扰，可能导致无法准确接收较弱信号，进而导致多载波同时工作的失败。
因此，本申请实施例提供了多载波通信方法，能够解决5G NR终端工作于毫米波频段且配置多载波时可能面临的问题。
图6是根据本申请一实施例的多载波通信方法200的示意性流程图。该方法可选地可以应用于图1所示的系统，但并不仅限于此。该方法包括以下内容的至少部分内容。
S210、终端设备向网络设备发送多载波通信能力信息，该多载波通信能力信息用于指示该网络设备对该终端设备进行多载波通信配置。
可选地，在本申请实施例中，该多载波通信能力信息包括多波束赋形能力。波束赋形是一种基于天线阵列的信号预处理技术，波束赋形可以通过调整天线阵列中每个天线阵子的加权系数产生具有指向性的波束，从而能够获得明显的阵列增益。多波束赋形能力表示能够产生具有指向性的多个波束的能力。终端设备向网络设备发送多载波通信能力信息，可以辅助网络设备对该终端设备进行多载波通信配置，有利于使终端设备成功地进行多载波通信。例如，防止出现在多载波通信中因终端设备不支持多载波独立波束赋形或载波间的功率谱密度差异过大等带来的多载波通信失败问题。
可选地，在本申请实施例中，该多波束赋形能力包括该终端设备是否支持多个独立波束赋形能力。独立波束赋形能力表示终端可以产生具有独立指向的两个及以上的波束的能力。
可选地，在本申请实施例中，该终端设备是否支持多个独立波束赋形能力，包括以下场景的至少之一；
场景一、该终端设备支持频段内的多个独立波束赋形能力。
场景二、该终端设备不支持频段内的多个波束赋形能力。
例如，终端设备可以按照频段上报波束赋形能力。上报的信息中，频段n对应的波束赋形能力的标识为1，表示终端设备支持频段n内的多个独立波束赋形能力；频段n对应的波束赋形能力的标识为0，表示终端设备不支持频段n内的多个独立波束赋形能力。
场景三、该终端设备支持频段组内的多个独立波束赋形能力。
场景四、该终端设备不支持频段组内的多个独立波束赋形能力。
例如，终端设备可以按照频段组上报波束赋形能力。频段n257、n258、n261属于频段组A，具有类似的波束赋形能力。上报的信息中，频段组A对应的波束赋形能力的标识为1，表示终端设备支持频段组A的各频段内的多个独立波束赋形能力；频段组A对应的波束赋形能力的标识为0，表示终端设备不支持频段组A的各频段内的多个独立波束赋形能力。终端按照频段组上报波束赋形能力，可以减少信令开销。
场景五、该终端设备支持频段组合的多个独立波束赋形能力。
场景六、该终端设备不支持频段组合的多个独立波束赋形能力。
例如，终端设备可以按照频段组合上报波束赋形能力。频段n257、n260不属于同一频段组，也具 有类似的波束赋形能力，可以将二者看做是频段组合。上报的信息中，频段组合对应的波束赋形能力的标识为1，表示终端设备支持频段组合的各频段内的多个独立波束赋形能力；频段组合对应的波束赋形能力的标识为0，表示终端设备不支持频段组合的各频段内的多个独立波束赋形能力。终端按照频段组合上报波束赋形能力，可以减少信令开销。
场景七、该终端设备支持频段组的组合的多个独立波束赋形能力。
场景八、该终端设备不支持频段组的组合多个独立波束赋形能力。
例如，终端设备可以按照频段组的组合上报波束赋形能力。频段n257、n258、n261属于频段组A，具有类似的波束赋形能力。n260、n259处于频段组B具有类似的波束赋形能力，频段组A和频段组B是一个频段组的组合。终端按照频段组的组合上报波束赋形能力，可以减少信令开销。
例如，终端上报支持频段组A和频段组B的多个独立波束赋形能力，频段组A内的任何频段与频段组B内的任何频段形成的组合，可以同时工作于不共站址的小区。这是因为，终端可以形成两个独立指向的波束来分别指向频段组A内的基站和频段组B内的基站。上报的信息中，频段组A对应的波束赋形能力的标识为1，表示终端设备支持频段组A的各频段内的多个独立波束赋形能力；频段组A对应的波束赋形能力的标识为0，表示终端设备不支持频段组A的各频段内的多个独立波束赋形能力。
网络设备收到终端设备是否支持多个独立波束赋形能力，可以配置终端设备的多载波通信。如果终端设备支持多个独立波束赋形能力，单个基站小区、共站址的多个基站小区或不共站址的多个基站小区可以根据上述场景，相应地配置终端设备进行频段内、频段组内、频段组合或频段组的组合的多载波通信。如果终端设备不支持多个独立波束赋形能力，单个基站小区或共站址的多个基站小区可以根据上述场景，相应地配置终端设备进行频段内、频段组内、频段组合或频段组的组合的多载波通信。
可选地，在本申请实施例中，该多波束赋形能力还包括该终端设备支持独立波束赋形的载波数量。网络设备收到终端设备支持独立波束赋形的载波数量后，可以基于该终端设备支持独立波束赋形的载波数量，配置不共站址基站发送的载波数量。
可选地，在本申请实施例中，该多波束赋形能力还包括该终端设备支持独立波束赋形的波束对应的极化方式。网络设备收到终端设备支持独立波束赋形的波束对应的极化方式后，可以基于该终端设备支持独立波束赋形的波束对应的极化方式，向该终端设备发射下行波束。例如，下行波束1对应水平极化，下行波束2对应垂直极化，主基站向终端设备发送水平极化的波束1，并指示辅基站垂直极化的波束2。
可选地，在本申请实施例中，该多载波通信能力信息包括该终端设备支持的载波间的功率谱密度最大差异能力。例如，功率谱密度可以为基站发射下行载波的功率与终端接收下行载波所用带宽的比值。
例如，终端设备上报其支持的载波1与载波2的功率谱密度最大差异能力为2dB，载波2与载波3的功率谱密度最大差异能力为3dB，载波1与载波3的功率谱密度最大差异能力为4dB。
可选地，在本申请实施例中，该载波间的功率谱密度最大差异能力通过RRC信令承载。
可选地，在本申请实施例中，该方法还包括：该终端设备发送载波间的功率谱密度差异信息。载波间的功率谱密度差异信息中可以包括载波间的功率谱密度差异，具体可以表示为差异值。如果终端设备测量到多个载波，可以发送每两个载波之间的载波间的功率谱密度差异信息，也可以发送所有载波之间的载波间的功率谱密度差异信息中包括最大差异值的差异信息。

再如，测量结果可以包括终端设备支持的频段n259内的载波1和频段n260内的载波2的功率谱密度差异信息，频段n259和频段n260为频段组合。
再如，终端设备支持频段n259内的载波1、频段n260内的载波2和终端设备支持频段n261内的载波3，测量结果可以包括：载波1和载波2的功率谱密度差异信息，载波2和载波3的功率谱密度差异信息，以及载波1和载波3的功率谱密度差异信息。
再如，终端设备支持频段n259内的载波1、频段n260内的载波2和频段n261内的载波3，如果载波1和载波2的功率谱密度差异值最大，测量结果可以包括：载波1和载波2的功率谱密度差异信息。
方式二、终端设备基于触发事件上报该载波间的功率谱密度差异信息。
可选地，在本申请实施例中，该触发事件包括以下至少之一：
该载波间的功率谱密度差异信息中的差异值大于第一门限。
例如，第一门限为2 dB，终端设备测量的载波1和载波2的差异值为4dB，载波2和载波3的差异值为1dB，则触发上报载波1和载波2的差异值。
当前测量的载波间的功率谱密度差异信息中的差异值与上一次上报的差异值的差值大于第二门限。
例如，第二门限为2 dB，终端设备当前测量的载波1和载波2的差异值为4dB，上一次上报载波1和载波2的差异值为1dB，二者的差值为3dB，则触发上报载波1和载波2的差异值。
图7是根据本申请一实施例的多载波通信方法300的示意性流程图。该方法可选地可以应用于图1所示的系统，但并不仅限于此。该方法包括以下内容的至少部分内容。
S310、终端设备向网络设备发送多载波通信配置调整请求，该多载波通信配置调整请求用于请求该网络设备对该终端设备的多载波通信配置进行调整。在本实施例中，终端设备也可以自己判断是否需要调整多载波通信配置，如果需要调整，则向网络设备发送多载波通信配置调整请求。具体地，终端设备可根据自身的载波间的功率谱密度最大差异能力和测量的载波间的功率谱密度差异信息判断是否需要调整。终端设备也可根据测量的载波间的功率谱密度差异信息中差异值的大小来判断是否需要调整。
可选地，在本申请实施例中，该方法还包括：该终端设备测量得到该终端设备支持的载波间的功率谱密度差异信息。
可选地，在本申请实施例中，终端设备向网络设备发送多载波通信配置调整请求，包括：该终端设备基于自身的载波间的功率谱密度最大差异能力和测量的载波间的功率谱密度差异信息，向该网络设备发送该多载波通信配置调整请求。例如，终端设备自身的载波间的功率谱密度最大差异能力为10dB，测量得到载波间的功率谱密度差异信息中的差异值为9dB，即将超过该能力(可以通过一个门限例如2dB来判断，比该能力小2dB及其以下的，判定为即将超过该能力)，可以向该网络设备发送该多载波通信配置调整请求。
可选地，在本申请实施例中，终端设备向网络设备发送多载波通信配置调整请求，包括：该终端设备在测量的载波间的功率谱密度差异信息中的差异值大于第三门限的情况下，向该网络设备发送该多载波通信配置调整请求。例如，设定第三门限为5dB，如果终端设备测量到载波间的功率谱密度差异信息中的差异值为6dB，则向该网络设备发送该多载波通信配置调整请求。
可选地，在本申请实施例中，该多载波通信配置调整请求用于请求该网络设备降低该终端设备的载波间的功率谱密度差异。一种情况下，网络设备可以调整该终端设备的载波间的功率和/或功率谱密度，以降低该终端设备的下行载波间的功率谱密度差异。例如，下行载波1比下行载波2的功率谱密度差异大于第三门限如6dB，将下行载波1的发射功率调低，将下行载波2的发射功率调高；或者，将下行载波1的功率谱密度调低，将下行载波2的功率谱密度调高。其中，降低载波的发射功率和/或提高终端接收载波的带宽，可以调低载波的功率谱密度。提高载波的发射功率和/或降低终端接收载波的带宽，可以调高载波的功率谱密度。

本申请实施例提供了终端辅助的多载波通信方法，可以用于NR系统中。通过终端上报其多载波通信能力信息例如多个独立波束赋形能力、可解调的载波间的功率谱密度最大差异能力等，辅助基站进行多载波配置。
示例1：终端上报多个独立波束赋形能力
在NR系统中，特别是毫米波频段，可能会面临终端因受限于天线阵形成窄波束的能力而导致基站配置载波的失败，导致多载波无法同时工作的问题。
例如，对终端与图10所示的多个不共站址基站进行多载波通信的问题进行分析。当基站1和基站2工作在同一个毫米波频段的多载波通信时，实际构成的是频段内连续或非连续多载波通信。根据毫米波终端的天线阵数量及波束赋形能力，可以划分为以下终端能力：
(1)终端具有一个天线阵列。图11a至图11c是终端波束赋形能力示意图。
在同一时刻终端只产生一个指向的窄波束，且其中包括了水平极化(H)和垂直极化(V)，如图11a所示。
在同一时刻终端能够同时产生两个指向的窄波束，且每个波束分别对应水平极化(H)和垂直极化(V)，如图11b所示。
在同一时刻终端能够同时产生两个指向的窄波束，且每个波束分别包含水平极化(H)和垂直极化(V)，如图11c所示。
(2)终端具有多个天线阵列
在同一时刻终端能够同时产生多个不同指向的波束。
在同一时刻终端只能同时产生一个指向的波束。
当基站1和基站2通过不同的毫米波载波与终端通信时，可以构成一个频段内或多个频段间的多载波通信。此时根据毫米波终端的天线阵数量及波束赋形能力，也可将终端划分为与频段内多载波通信类似的终端能力。
但是，对于一个终端来说其支持的频段内多载波通信和频段间多载波通信能力可能是不完全相同的。例如，对于只具有一个天线阵列的终端来说，它可能可以支持频段内频率间隔不大的多载波同时通信。再如，对于频段间的多载波通信来说，频率差异过大导致无法同时支持频段间多载波通信。
以上波束赋形的能力与具体终端实现有关，不同的终端其能力可能会不同。这些终端能力对于基站来说是不知道的。因此，对于某些终端，当其将波束指向一个基站并保持通信时，实际该终端可能并不能跟另外一个基站进行通信，进而导致多载波配置上面的失败问题。
为了解决该问题，终端可以将其多个独立波束赋形能力在初始接入网络时通过该RRC信令方式上报给基站，以辅助基站进行载波配置和下行发射信号的波束赋形等操作。示例性地，上报方式可以为：
方式一、对于每个毫米波频段，或频率相近的频段组(如图4中的n257、n258、n261可视为一组)，终端上报其支持的多个独立波束赋形能力，也即终端可以形成多个独立波束来指向不同位置的同频段基站或同频段组基站。适用于频段内或频段组内多载波通信。
多个独立波束赋形能力可以为简单的指示终端是否支持多个独立波束赋形能力，也可以是指示终端能具体支持的独立波束赋形的载波数量。
方式二、对于每个毫米波频段组合(如图4中的n257+n260)终端上报其支持的多个独立波束赋形能力，也即终端可以形成多个独立波束来指向不同位置的基站。或者，对于毫米波频段组的组合(如图4中可以认为n257、n258、n261处于同一个A频段组具有类似的波束赋形能力，而n260、n259处于B频段组具有类似的波束赋形能力，那么A+B就是一个频段组的组合)，终端上报其支持的多个独立波束赋形能力。适用于频段间多载波通信。
多个独立波束赋形能力可以为简单的指示其是否支持多个独立波束赋形能力，也可以是指示其能具体支持的独立波束赋形的数量
当基站获取到终端的多个独立波束赋形能力后，可根据不同场景进行的操作如下：
场景一、对于不支持频段内多个独立波束赋形能力的终端，可在单个基站小区，或者共站址的多基站小区，配置终端进行频段内多载波通信。
场景二、对于支持频段内多个独立波束赋形能力的终端，可在单个基站小区、共站址的多基站小区、不共站址的多基站小区，配置终端进行频段内多载波通信。
场景三、对于不支持频段组内多个独立波束赋形能力的终端，可在单个基站小区、共站址的多基站小区，配置终端进行频段组内的频段间多载波通信。
场景四、对于支持频段组内多个独立波束赋形能力的终端，可在单个基站小区、共站址的多基站小区、不共站址的多基站小区，配置终端进行频段组内的频段间多载波通信。
场景五、对于不支持频段组合或频段组的组合多个独立波束赋形能力的终端，可在单个基站小区，或者共站址的多基站小区，配置终端进行频段间多载波通信；
场景六、对于支持频段组合或频段组的组合多个独立波束赋形能力的终端，可在单个基站小区、共站址的多基站小区、不共站址的多基站小区，配置终端进行频段间的多载波通信；
通过上报终端支持的独立多波束赋形能力，基站可以识别终端能支持的多载波工作场景，进而避免多载波配置失败的问题。
示例2：终端上报载波间的功率谱密度能力
在NR系统中，特别是在毫米波频段，由于两个载波间的大传播损耗差异，可能引起终端接收到的两个载波的信号功率谱密度相差很大。进而，可能导致终端内低噪声放大器(LNA)在同时放大两个接收信号时，强信号对弱信号产生干扰，导致终端无法准确接收较弱信号，进而导致多载波同时工作的失败。
上述问题的产生包括多方面的因素：首先，载波间的工作频率差异，也即频率差异越大则该问题越严重；其次，终端的接收能力，也即能正确接收解调的信号间功率谱密度差异，接收能力越强则可承受的信号间功率谱密度差异越大。
终端的载波间接收功率谱密度差异跟终端实现情况有关。图12a和图12b是终端可解调的载波间的功率谱密度最大差异能力示意图。如图12a和图12b所示，终端可以采用一套天线阵或多套(例如两套)独立天线阵及相应的LNA来接收多个例如(两个)载波等。通常情况下，当终端具有多个天线阵及相应的LNA等接收链路时，终端可独立接收不同的载波。此时两个接收链路可以分别工作于不同的频点，链路间具有一定的抑制度，其能接收的功率谱密度差异就可以相对较大。当采用同一套天线阵及相应的LNA来接收两个载波时，其能接收的功率谱密度差异就会相对较小。
上述终端可接收解调的载波间的功率谱密度最大差异能力目前对于基站来说是未知的。当基站配置 的多个载波功率谱密度差异过大时，终端无法接收解调的问题。本申请实施例，终端可以指示基站其可解调的载波间的功率谱密度最大差异能力。该能力的指示可通过以下方式实现：
方式一：终端针对各频段组合，上报其能支持的载波间的功率谱密度最大差异能力。如图13所示，该方式可以包括以下步骤：
S601、终端在初始接入时将其能支持的载波间的功率谱密度最大差异能力通过RRC信令方式上报给网络设备例如基站。
S602、网络设备配置终端进行周期性测量并，并进行载波间的功率谱密度差异测量。
S603、终端上报测量结果，以反馈载波间的功率谱密度差异信息。
终端基于事件触发的测量反馈载波间的功率谱密度差异信息。触发方式示例如下：
如果差异值大于某个门限(如2dB)，终端将该差异值上报给基站；或者，
如果当前测量的差异值跟上次上报的差异值的差值大于某个门限(如2dB)，终端将当前测量的差异值上报给基站。
S604、基站根据终端上报的测量结果，当载波间的功率谱密度差异超过终端能力时，降低终端的载波间的功率谱密度差异。基站收到载波间的功率谱密度差异信息后，如果其中的差异值超过终端上报的能力，基站可以调整载波间的功率及对应的功率谱密度，以避免终端因功率谱密度差异过大导致的载波接收解调问题。
方式二：终端指示网络载波间的功率谱密度差异过大，请求降低载波间的功率谱密度差异。
在该方式中，终端不需要向网络上报其各个频段组合能支持的功率谱密度最大差异能力。如图14所示，该方式可以包括以下步骤：
S701、基站配置终端进行多载波通信。
S702、终端测量载波间的功率谱密度差异。
S703、当载波间的功率谱密度差异超过门限时，终端上报网络请求降低终端的载波间的功率谱密度差异。或者，终端基于实时测量结果与其能支持的载波间的功率谱密度最大差异能力相比较。当测量结果即将超过其能力时，例如测量结果与其能力差为2dB时，终端上报网络请求降低终端的载波间的功率谱密度差异。
S704基站收到该请求后，可以降低终端的载波间的功率谱密度差异。
本申请实施例，可辅助基站规避在多载波通信中因终端不支持多载波独立波束赋形或载波间的功率谱密度差异过大等带来的多载波通信失败问题。
