Description

功率控制方法、用户设备、基站及计算机可读存储介质 技术领域
本公开涉及通信技术领域，具体而言，本发明涉及一种功率控制方法、用户设备、基站及计算机可读存储介质。
背景技术
在多载波系统中，比如包括载波聚合技术(Carrier aggregation，CA)和双链接技术(Dual Connectivity，DC)，当多个频率相近的成员载波间功率不平衡会造成严重的镜像干扰(image interference)，这主要是由于用户设备(User Equipment，UE)接收电路的同向正交(In-phase/Quadrature，I/Q)增益不平衡和积分偏差会产生镜像信号，当一个成员载波的镜像信号落入到另外一个成员载波上会就产生镜像干扰。
但是，在某些情况下，例如各成员载波所要求的载波覆盖区域不同时，它们聚合后就会导致成员载波上的功率相差很大。这样，功率较大的成员载波的镜像在功率较小的成员载波上会产生较大的镜像干扰，从而影响该成员载波上的解调性能，造成载波聚合的整体通信性能的下降，严重时会造成通信中断。

本公开实施例提供了一种功率控制方法，由用户设备执行，如图1所示，该方法包括：
步骤S101、确定各载波分别对应的参考信号接收功率(Reference Signal Receiving Power，RSRP)。
对于本公开实施例，用户设备可以被配置一个主载波和至少一个副载波。在本公开实施例中，用户设备可以确定各个载波(包括主载波和至少一个副载波)分别对应的RSRP。在本公开实施例中，RSRP是长期演进(Long Term Evolution，LTE)网络中可以代表无线信号强度的关键参数以及物理层测量需求之一，是在某个符号内承载参考信号的所有资源粒子(Resource Element，RE)上接收到的信号功率的平均值。
对于本公开实施例，在EN-DC中将LTE的主载波作为主载波，将在LTE上的其它载波和NR上的载波可作为副载波。在NE-DC中，将NR的主载波作为主载波，将NR上其它载波和LTE上的载波可作为副载波。
步骤S102、基于各载波分别对应的RSRP，确定满足第一预设条件的载波。
其中，满足第一预设条件的载波为产生镜像干扰的载波。
其中，满足第一预设条件的载波可以为主载波，也可以副载波。
对于本公开实施例，第一预设条件也可以称为功率不平衡镜像干扰的产生条件，也即，满足第一预设条件的载波也可以称为满足功率不平衡镜 像干扰的产生条件的载波。
步骤S103、将满足第一预设条件的载波对应的指示信息上报至基站，以使得基站调整满足第一预设条件的载波的发射功率。
对于本公开实施例，若满足第一预设条件的载波仅有一个，则用户设备将该满足第一预设条件的载波对应的指示信息上报至基站，以使得基站根据上报的指示信息，对该载波的发射功率进行调整。
对于本公开实施例，若满足第一预设条件的载波包含至少两个，则用户设备将各个满足第一预设条件的载波分别对应的指示信息上报至基站，以使得基站基于对各个满足第一预设条件的载波的发射功率分别各自对应的各个指示信息进行调整；或者也可以仅上报给基站一个指示信息，以使得基站基于该指示信息对各个满足第一预设条件的载波的发射功率进行调整；又或者，也可以上报给基站至少两个指示信息，以使得基站可以基于每个指示信息对至少一个满足第一预设条件的载波的发射功率进行调整。
本公开实施例提供了一种功率控制方法，与现有技术相比，本公开实施例确定各载波分别对应的参考信号接收功率RSRP，然后基于各载波分别对应的RSRP，确定满足第一预设条件的载波，满足第一预设条件的载波为产生镜像干扰的载波，然后将满足第一预设条件的载波对应的指示信息上报至基站，以使得基站调整满足第一预设条件的载波的发射功率，从而可以避免各个载波的功率相差较大，进而可以降低某些载波的解调性能的影响，避免造成载波聚合的整体通信性能的下降。
本公开实施例的一种可能的实现方式，该方法还可以包括：确定各载波分别对应的参考信号接收质量(Reference Signal Receiving Quality，RSRQ)。
对于本公开实施例，在确定出各载波分别对应的RSRQ之后，本公开实施例的另一种可能的实现方式，基于各载波分别对应的RSRP确定满足第一预设条件的载波，具体可以包括：基于各载波分别RSRP以及RSRQ，确定满足第一预设条件的载波。
对于本公开实施例，用户设备可以被配置一个主载波和至少一个副载 波。在本公开实施例中，用户设备可以确定各个载波(包括主载波和至少一个副载波)分别对应的RSRP以及各个载波(包括主载波和至少一个副载波)分别对应的RSRQ。RSRQ表示LTE参考信号接收质量，这种度量主要是根据信号质量来对不同LTE候选小区进行排序，这种测量用作切换和小区重选决定的输入。
对于本公开实施例，若用户设备被配置有一个主载波和一个副载波，则基于该主载波对应的RSRP与该副载波对应的RSRP确定满足第一预设条件的载波，也可以基于该主载波对应的RSRP与该副载波对应的RSRP以及该主载波对应的RSRQ以及该副载波对应的RSRQ，确定满足第一预设条件的载波。
对于本公开实施例，若用户设备被配置有一个主载波以及至少两个副载波，则基于该主载波对应的RSRP与各个副载波分别对应的RSRP，确定满足第一预设条件的载波；也可以基于该主载波对应的RSRP与各个副载波分别对应的RSRP，以及该主载波对应的RSRQ以及各个副载波分别对应的RSRQ确定满足第一预设条件的载波。
本公开实施例的一种可能的实现方式，基于各载波分别对应的RSRP，确定满足第一预设条件的载波，包括：确定第一RSRP以及至少一个第二RSRP；基于至少一个第二RSRP中每个RSRP与第一RSRP之间的关系，确定满足第一预设条件的载波。
其中，第一RSRP为主载波对应的RSRP，第二RSRP为副载波对应的RSRP。
对于本公开实施例，若用户设备仅被配置为一个主载波和一个副载波，则基于该主载波和该副载波分别对应的RSRP之间的关系，确定该副载波是否为满足第一预设条件的载波(满足功率不平衡镜像干扰的产生条件的载波)，具体的实现方式详见下述实施例，在此不再赘述。
对于本公开实施例，若用户设备被配置有至少三个载波(可以包含一个主载波和至少两个副载波)，则确定各个载波分别对应的RSRP(主载波对应的RSRP以及各个副载波分别对应的RSRP)，并基于各个副载波分别对应的RSRP分别与主载波对应的RSRP之间的关系，确定满足第一 预设条件的载波，具体实现方式详见下述实施例，在此不再赘述。
本公开实施例的另一种可能的实现方式，基于至少一个第二RSRP中每个RSRP与第一RSRP之间的关系，确定满足第一预设条件的载波，包括：确定每个第二RSRP与第一RSRP之间的差值的绝对值；将绝对值大于第一预设阈值的第二RSRP所对应的副载波确定为满足第一预设条件的载波。
对于本公开实施例，若用户设备仅被配置为一个主载波和一个副载波，第一RSRP(主载波对应的RSRP)可以通过RSRP P进行表征，第二RSRP(副载波对应的RSRP)可以用RSRP S进行表征，则根据|RSRP P-RSRP S|是否大于M dB(第一预设阈值)确定该副载波是否为满足第一预设条件的副载波；若|RSRP P-RSRP S|大于M dB，则确定该副载波为满足第一预设条件的副载波，若|RSRP P-RSRP S|不大于M dB，则确定该副载波不为满足第一预设条件的副载波。在本公开实施例中，第一预设阈值可以预先设置，例如为6dB。
对于本公开实施例，若用户设备被配置为至少三个载波，即包括：一个主载波和至少两个副载波，例如，主载波P所对应的RSRP为RSRP P，其它n个副载波S对应的RSRP为RSRP SK(k＝1、2、…、n)，则根据|RSRP C-RSRP Sj|是否大于第一预设阈值(M(dB))以确定满足第一预设条件的载波，其中j＝1、2、…、n，M是功率不平衡门限值，如果判断大于M dB，则认为满足第一预设条件(功率不平衡镜像干扰条件)，且将|RSRP C-RSRP Sj|大于MdB所对应的副载波确定为满足第一预设条件的副载波，否则，认为不满足第一预设条件(功率不平衡镜像干扰条件)，且不存在满足第一预设条件的副载波(也可以称为不存在功率不平衡镜像干扰条件的副载波)。
本公开实施例的另一种可能的实现方式，基于各载波分别对应的RSRP以及各个载波分别对应的RSRQ，确定满足第一预设条件的载波，包括：确定第一RSRP以及至少一个第二RSRP；响应于至少一个第二RSRP与第一RSRP之间的关系满足第二预设条件，确定主载波对应的RSRQ，并确定主载波对应的RSRQ与第二预设阈值之间的关系；基于主 载波对应的RSRQ与第二预设阈值之间的关系，确定满足第一预设条件的载波。
其中，第一RSRP为主载波对应的RSRP，第二RSRP为副载波对应的RSRP。
其中，至少一个第二RSRP与第一RSRP之间的关系满足第二预设条件包括：至少一个第二RSRP大于第一RSRP，且至少一个第二RSRP与第一RSRP之间的差值大于第三预设阈值。
对于本公开实施例，当用户设备被配置为两个载波(一个主载波和一个副载波)，则用户设备确定该主载波和该副载波之间是否满足第二预设条件，当该副载波与主载波之间的关系满足第二预设条件，则确定主载波对应的RSRQ，并进一步地的确定主载波对应的RSRQ与第二预设阈值的关系，确定满足第一预设条件的载波(满足功率不平衡镜像干扰条件的载波)。
对于本公开实施例，当用户设备被配置为两个载波(一个主载波和一个副载波)，确定该主载波和该副载波之间是否满足第二预设条件的具体方式为：确定该副载波对应的RSRP(第二RSRP)是否大于该主载波对应的RSRP(第一RSRP)，且该副载波对应的RSRP(第二RSRP)与该主载波对应的RSRP(第二RSRP)之间的差值是否大于第三预设阈值。在本公开实施例中，第一预设阈值与第三预设阈值可以相同，也可以不同，在本公开实施例中，不做限定。
对于本公开实施例，当用户设备被配置为至少三个载波(一个主载波和至少两个副载波)，用户设备确定该主载波和该各个副载波之间是否满足第二预设条件，当存在副载波与主载波之间的关系满足第二预设条件，则确定主载波对应的RSRQ，并进一步地的确定主载波对应的RSRQ与第二预设阈值的关系，确定满足第一预设条件的载波(满足功率不平衡镜像干扰条件的载波)。
本公开实施例的另一种可能的实现方式，基于主载波对应的RSRQ与第二预设阈值之间的关系，确定满足第一预设条件的载波，包括：响应于主载波对应的RSRQ小于第二预设阈值，确定主载波为满足第一预设条件 的载波；响应于主载波对应的RSRQ不小于第二预设阈值，确定满足第二预设条件的至少一个RSRP分别对应的副载波为满足第一预设条件的载波。
对于本公开实施例，当用户设备被配置两个载波(一个主载波和一个副载波)，且该副载波对应的RSRP与该主载波对应的RSRP之间的关系满足第二预设条件，且该主载波对应的RSRQ小于第二预设阈值，则确定该主载波为满足第一预设条件的载波(满足功率不平衡镜像干扰条件的载波)，若该副载波对应的RSRP与该主载波对应的RSRP之间的关系满足第二预设条件，且该主载波对应的RSRQ不小于第二预设阈值，则确定该副载波为满足第一预设条件的载波。
对于本公开实施例，当用户设备被配置至少三个载波(一个主载波和至少两个副载波)，且存在副载波对应的RSRP与该主载波对应的RSRP之间的关系满足第二预设条件，且该主载波对应的RSRQ小于第二预设阈值，则确定该主载波为满足第一预设条件的载波(满足功率不平衡镜像干扰条件的载波)，若该副载波对应的RSRP与该主载波对应的RSRP之间的关系满足第二预设条件，且该主载波对应的RSRQ不小于第二预设阈值，则确定满足第二预设条件的副载波为满足第一预设条件的载波(满足功率不平衡镜像干扰条件的载波)。
例如，某副载波Sj的RSRP比主载波的RSRP大，且满足功率不平衡镜像干扰条件，即RSRPSj-RSRPC>M>0,此时判断满足第一预设条件的载波(满足功率不平衡镜像干扰条件的载波)时，还需看主载波上的RSRQ是否大于第二预设阈值，以确定满足第一预设条件的载波(满足功率不平衡镜像干扰条件的载波)；如果判断主载波上的RSRQ小于该第二预设阈值，则该主载波可被定为满足第一预设条件的载波(满足功率不平衡镜像干扰条件的载波)。
本公开实施例的另一种可能的实现方式，响应于载波个数大于第四预设阈值，则步骤S102以及步骤S102，具体可以包括：确定第一RSRP以；确定至少一个第三RSRP；基于第一RSRP以及第一RSRQ中的至少一项以及至少一个第三RSRP，确定满足第一预设条件的载波。
其中，第一RSRP为主载波对应的RSRP；至少一个第三RSRP为与主载波相邻的至少一个副载波中各个副载波分别对应的RSRP。
对于本公开实施例，响应于载波个数大于第四预设阈值，为了减少不必要的信令损耗，可以不对所有的副载波均进行功率不平衡镜像干扰判断，而仅对主载波所相邻的副载波进行功率不平衡镜像干扰判断。也即基于主载波对应的RSRP以及与之相邻的至少一个副载波的RSRP，确定满足第一预设条件的载波。在本公开实施例中，确定满足第一预设条件的载波的方式详见上文，在此并不在赘述。
本公开实施例的另一种可能的实现方式，响应于载波大于第四预设阈值，确定各载波分别对应的RSRP以及RSRQ；基于各载波分别RSRP以及RSRQ，确定满足第一预设条件的载波，具体可以包括：确定第一RSRP以及第一RSRQ；确定至少一个第三RSRP以及至少一个第三RSRQ；基于第一RSRP以及至少一个第三RSRP、以及第一RSRQ以及至少一个第三RSRQ，确定满足第一预设条件的载波。

对于本公开实施例，当载波个数大于第四预设阈值，为了减少不必要的信令损耗，可以不对所有的副载波均进行功率不平衡镜像干扰判断，而仅对主载波所相邻的副载波进行功率不平衡镜像干扰判断。也即基于主载波对应的RSRP以及与之相邻的至少一个副载波的RSRP，以及基于主载波对应的RSRQ以及与之相邻的副载波对应的RSRQ，确定满足第一预设条件的载波。在本公开实施例中，确定满足第一预设条件的载波的方式详见上文，在此并不在赘述。

对于本公开实施例，功率调整步长用于指示基站对满足第一预设条件的载波的发射功率增大或者减小的值；功率调整方向用于指示基站对满足第一预设条件的载波的发射功率进行增大还是减小。
对于本公开实施例，上报的载波标识可用m个比特(bit)表示，上报的nbit来表示，功率调整方向可用kbit来表示，其中，k可以为1。在本公开实施例中不做限定。
本公开实施例的另一种可能的实现方式，将满足第一预设条件的载波对应的载波标识以及功率调整信息中的至少一项上报至基站，包括以下至少一项：确定满足第一预设条件的载波各自对应的功率调整信息，并通过满足第一预设条件的载波向基站上报各自对应的功率调整信息；确定满足第一预设条件的载波各自对应的载波标识以及功率调整信息，并通过预设载波向所述基站上报满足第一预设条件的载波各自对应的载波标识以及功率调整信息。
其中，预设载波为主载波或者预设副载波，且预设副载波所承载的功率调整信息包含不属于预设副载波对应的功率调整信息。
本公开实施例的一种可能的实现方式，用户设备可以满足第一预设条件的载波将其自身对应的功率调整信息上传至基站，以使得基站基于该功率调整信息调整该满足第一预设条件的载波对应的发射功率。
例如，满足第一预设条件的载波为载波1和载波2，则用户设备通过载波1将载波1对应的功率调整信息1发送至基站，通过载波2将载波2对应的功率调整信息2发送至基站，以使得基站基于功率调整信息1调整载波1对应的发射功率，以及功率调整信息2调整载波2对应的发射功率。
本公开实施例的另一种可能的实现方式，若用户设备通过主载波或者预设副载波，且该预设副载波中承载的功率调整信息包含不属于该副载波的功率调整信息，则用户设备可以将各个满足第一预设条件的载波对应的标识和各自对应的功率调整信息上报至基站，以使得基站确定出满足第一预设条件的载波以及各个载波分别对应的功率调整信息。
例如，满足第一预设条件的载波为载波1和载波2，则用户设备可以通过主载波将载波1对应的载波标识1和功率调整信息1以及载波2对应标识2和功率调整信息2发送至基站，以使得基站基于载波标识1确定满足第一预设条件的载波为载波1，并基于功率调整信息1调整载波1对应的发射功率，以及基于载波2对应的载波标识2确定满足第一预设条件的载波为载波2，以及基于功率调整信息2调整载波2的发射功率。

其中，第一绝对值为主载波对应的RSRP与任一满足第一预设条件的载波对应的RSRP之间的差值的绝对值。
对于本公开实施例，基于任一满足第一预设条件的载波对应的功率调整步长＝|RSRPC-RSRPSj|-M确定，其中RSRPSj为所述任一满足第一预设条件的载波对应的RSRP，RSRPC为主载波对应的RSRP，M为第一预设阈值。

本公开实施例的另一种可能的实现方式，响应于指示信息中携带功率调整信息，步骤S202具体可以包括：将承载指示信息的载波确定为满足第一预设条件的载波；基于功率调整信息调整满足第一预设条件的载波。
对于本公开实施例，若指示信息中不包含载波标识，则基站将承载指示信息的载波确定为满足第一预设条件的载波，并基于指示信息中携带的功率调整信息调整该满足第一预设条件的载波对应的发射功率。
对于本公开实施例，由上述实施例中，功率调整信息包括以下至少一项：功率调整步长以及功率调整方向；功率调整目标值。在本公开实施例中，若功率调整信息中携带功率调整目标值，则基站将对应的满足第一预设条件的载波对应的发射功率调整至该功率调整目标值；若功率调整信息中包含功率调整步长以及功率调整方向，则根据功率调整步长以及功率调整方向调整对应的满足第一预设条件的载波的发射功率。
