Description

一种功率分配方法及装置

技术领域
本申请涉及通信领域，尤其涉及一种基于用户位置与流量分布的功率分配方法及其装置。
背景技术
当前长期演进(long term evolution，LTE)与新无线接入(new radio，NR)技术在进行下行功率控制时主要为静态控制。而静态控制是终端根据各个信道或者信号的覆盖能力，进行基准功率或者功率偏置的参数配置，然后根据确定的参数配置调整上行信道的发射功率。
然而在无线网络的覆盖中，例如图1中的一个基站(base station，BS)位于三个彼此相邻小区的交汇点，一个小区被该基站覆盖的区域即为一个扇区。一般一个小区对应一个扇区，但在实际的一些情况下，也会存在多个扇区合并为一个小区，例如可以由3个扇区构成一个小区。为了简化小区与扇区的概念，可以通俗的认为一个扇区等同于一个小区。对于同一个小区的不同频点之间，用户分布数量差异是比较明显。正如图1中示出的两个频点F1和F2，其中频点可以表示为固定频率的编号，通常情况下频点也可以表示以固定频率为中心频点的一个频率范围。当然在一个例子中，F1、F2可以为F频段的两个频点，频率范围可以是1885-1915MHz。其中，F1频点的频率范围可以是1885-1905MHz，中心频点可以是1895MHz；F2频点的频率范围可以是1904.4-1914.4MHz，中心频点可以是1909.4MHz。显然，两个不同频点用户分布的数量差异明显，例如F1频点仅分布1个用户，而F2频点分布了5个用户。当然对于同一个小区的不同频点之间数据业务的波动也是十分明显的，例如图2示出的。可以看出，小区1的F1频点与同为小区1的F2频点的数据业务波动完全不同。对于小区2和小区3亦是如此。
显然，对于不同小区以及相同小区的不同频点，可以配置不同的功率，以达到保证通信质量的同时，还可避免相互之间的干扰。

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。
本申请主要应用在多个小区之间进行功率共享的场景。图3为一种应用场景示意图。功率共享组内可以包括有多个小区，例如功率共享组1内包含有小区1至小区7，功率共享组2内包含小区8至小区10，以及功率共享组3内包含有小区11至小区14。当然可以理解的是，还可以更多的功率共享组，并且对于每一个功率共享组内的小区数量也可以是其他任意数值。对于每个功率共享组，组内的多个小区共用一定额度的功率，即组内的多个小区之间共享功率。共享功率是指对于多模基站，当一个小区的功率利用率低时，该小区可将空闲的功率共享给组内的其他小区使用。当然，若组内的其他小区出现功率利用率低的情况时，组内的其他小区同样可将空闲的功率共享给该小区使用。
对于功率共享的场景的实际物理连接可以例如图4所示。图4示出了一种有源天线单元(active antenna unit，AAU)与基带处理单元(base band unit，BBU)连接关系示意图。其中，AAU为基站射频模块(radio unit，RU)与天线(antenna unit，AU)的集成部件。BBU主要用于完成基站基带信号的处理。可以理解的是，同一个功率共享组的多个小区共用一个AAU，可以简称共AAU。其中不同的小区可能对应着不同的频点，多个小区共用一个AAU，也就意味着多个频点可以共用一个AAU。如图4示出的，每个小区的AAU可以包括宏(macro)AAU、光纤(optical fiber)以及微型(micro)AAU，不同小区的AAU可以通过光纤传输网络与BBU相连接。而通过BBU相连接的多个AAU可以看做一个整体，即多个通过BBU相连接的AAU可以看作为一个AAU，从而使得互相连接的多个小区共AAU。
值得注意的是，在本申请中“功率共享组”与“共AAU”可以理解为相同的含义。
对于共AAU中的多个小区之间，功率是可以共享的，例如图5示出的一种功率共享示意图。图5中的灰色功率部分示意出了一种共AAU的功率池。对于该共AAU内的多个小区，也意味着需要共同使用该共AAU中功率池中的功率。共AAU的功率池可以看作该共AAU可以使用的全部功率。其中，例如该共AAU内的LTE小区使用了功率池中的一部分功率，而该共AAU内的NR小区也使用了功率池中的一部分功率。但是可能在某些时刻下，LTE小区的功率并不一定可以完全利用，对于并未利用到的空闲功率，则可以分配给该共AAU内的NR小区使用，实现了小区之间的功率共享。当然可以理解的是，对于该共AAU内的全部功率均可针对该共AAU内的不同小区之间实现功率共享。通过将功率共享组(共AAU)内的小区的剩余功率共享给其他有数传需求且功率受限的小区，从而提高功率利用率和小区业务的吞吐率，并提升用户感受。
在一个例子中，对于一个共AAU中LTE小区与NR小区共享功率的情况，由于LTE的站点密度比NR的站点密度要高，因此可以进行网络级的联合调整，从而达到相应的优化目标。例如图6示出的对于一个共AAU内，可以将功率池中的一部分功率分给LTE小区使用，另一部分功率分给NR小区使用。例如将功率池的功率P分为P LTE和P NR，然后再针对LTE小区或NR小区进行细分。例如，NR1小区分配d1功率、NR2小区分配d2功率、LTE1小区分配d3功率、LTE3小区分配d4功率、LTE2小区分配d5功率。通过对共AAU内的多个小区进行功率分配后，可能将原本LTE小区的部分功率分给了NR小区使用，从而提升了NR小区的吞吐率，并且降低了LTE小区的干扰，从而提升LTE小区的服务质量。反之，也有可能将原本NR小区的部分功率分给了LTE小区使用，从而提升LTE小区的覆盖能力。
在一些方案中，可以通过移动台(mobile station，MS)的单向功率控制，从而实现功率调整。移动台表示移动用户的终端设备，例如手机、平板电脑、可穿戴设备、车载设备等等。例如，移动台根据接收到基站的导频信号强度，衡量该移动台与基站之间的传播损耗， 从而确定发射功率的大小。使移动台的发射功率控制在一定的范围内。如果移动台接收功率较小，则表示前向链路(下行链路)损耗较大，移动台则可以认为反向链路(上行链路)的损耗也很大。因此移动台可以增大自身的发射功率。相反，若移动台接收功率较大，则减小移动台的发射功率。通过移动台自身进行功率控制，显然该方案仅针对单一用户。例如图7示出的一种单向功率调整示意图。MS 1通过接收到的基站的导频信号强度确定接收到的功率为
Figure PCTCN2020137293-appb-000001
并判断前向链路的功率损耗，然后MS 1控制自身的发射功率为
Figure PCTCN2020137293-appb-000002
以使得弥补对应的反向链路的损耗。同理，对于MS 2则根据接收到
Figure PCTCN2020137293-appb-000003
功率，控制自身的发射功率调整为
Figure PCTCN2020137293-appb-000004
显然对于不同的MS，各自控制自身的发射功率也不相同。可以看出，该方案仅仅是在但小区中针对自身服务的移动台进行功率的调整，该调整则会导致不同小区之间的多个移动台之间存在相互干扰。例如可能会出现“远近效应”等问题。“远近效应”是与基站距离较近的MS将会干扰到与基站距离较远的MS的现象。
当然在另一些方案中，针对某一个频点，移动台在工作发送信号时，相对于服务小区是有用信号，而对于非服务小区而言则是干扰信号。因此对于不同小区所接收到的有用信号和干扰信号是不同的。根据各个小区接收到的信号与干扰的比例，调整移动台的发射功率至合理水平，从而给整个网络的性能带来增益。显然该方案调整功率是网络级别的，而不是针对某个基站，或是某个移动台。例如图8示出的一种网络级功率调整示意图，可以看出，每个移动台发送的信号仅仅对该移动台所处的服务小区是有用信号。相对于其他相邻小区而言则是干扰信号。针对多个运行商存在多个频点而言，其中部分小区或者全部小区为共AAU小区，即从同一个功率池中分配功率。对于单频点而言，功率的优化仅仅是从该频点的网络优化角度进行的调整，很可能导致共AAU中功率池的功率没有使用完，或者某个重要的频点整体网络性能比较差，从而无法保障整体频谱的效率最优、各小区服务质量最优、最节能或者负荷更均匀。因此控制功率分配成为了网络下行规划以及优化的关键问题。
本申请针对网络中不同频点的小区之间进行功率共享，对于同一物理区域内，可能存在多个不同的频点，各小区对应的基站数量、基站位置、小区服务的用户数以及负荷也均不相同。因此通过采集各个小区的参数信息，根据不同的优化目标对共AAU内的多个小区进行功率分配。针对同一个小区的不同频点，以及多个不同小区之间进行功率分配，即合理配置发射功率。解决了不同频点的多个小区之间的干扰，同时保证了网络性能的最优。通过为不同物理信道和物理信号配置不同的功率，可以使得整体网络系统性能最优化，并且有效提升网络覆盖质量和用户业务体验，如某个频点吞吐率最优、整网吞吐率最优、负荷最均衡或功耗最低(最节能)。
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详细描述。
图9为本申请实施例提供的一种功率分配系统框架示意图。
如图9所示，本申请首先通过数据采集模块901采集各小区的参数信息。数据采集模块901可以通过基站采集不同小区的参数信息。当然在一些情况下，也可以通过人工的方式进行采集，例如工作人员采用终端设备直接采集小区的参数信息。然后数据处理模块902根据采集到的不同小区的参数信息计算各小区的特征信息，以及构建多频点模型。计算的特征信息例如可以是路损信息、位置信息和/或负荷信息等。然后根据采集到的参数信息以及计算得到的路损信息，构建多频点模型。功率分配模块903依据不同的优化目标，通过频点模型得到共AAU内各小区的发射功率。通过优化算法获取特定优化目标的功率分配方案。通过命令下发模块904将不同小区的发射功率下发至对应小区的基站。不同小区对应着相同或不同的 频点，例如频点f1、f2以及f3。将功率池中的功率分别按照计算好的发射功率进行分配，以使得各个小区之间不再相互干扰，并且可以满足预期的优化目标。
图10为本申请实施例提供的另一种功率分配系统框架示意图。
如图10示出的，数据处理模块902还可以根据预设配置，构建多频点模型；以及功率分配模块903也可以参考预设配置获取特定优化目标的功率分配方案。预设配置是在进行功率分配之前预先设置的特定信息，例如可以是一些变量的约束、预设的阈值、不同频点对应的优先级、不同功率共享组的功率约束以及特定的优化目标等信息。
图11为本申请实施例提供的一种功率分配方法流程图。
如图11所示，提供了一种功率分配方法，该方法应用于图9和图10中示出系统框架，该方法可以包括以下步骤：
S1101，采集多个小区中各小区的参数信息。
通过数据采集模块901采集多个小区的参数信息。其中采集的多个小区所处的区域可能不同，例如采集的区域包括某某城区以及某某县等。参数信息可以包括各小区的测量报告(measurement report，MR)、各小区的发射功率信息、各小区的负荷信息或功率共享组信息。其中，功率共享组信息也可以称为共AAU信息，共AAU信息记录了该小区与哪些其他小区共AAU。在一个例子中，数据采集模块901可以通过网管工具来实现多个小区的参数信息采集。其中，采集到的MR可如表1所示。
Figure PCTCN2020137293-appb-000005
表1
当然，在一些例子中，参数信息还可以包括各小区的位置信息、各小区的频点信息、以及各小区连接的AAU的型号信息等。其中，位置信息可以单独存在，或是在MR中包含。在一个例子中，MR中还可以包含小区的位置信息，例如经纬度，可以如表2所示。
小区ID 经度 纬度
123 104.027 30.618
456 189.473 28.796
… … …
表2
对于参数信息中包括各小区的发射功率信息、各小区的频点信息以及各小区连接的AAU的型号信息，可以例如表3示出的。其中，参数信息中还可以包括如小区的带宽和AAU柜框槽号。其中AAU柜框槽号用于描述AAU与BBU的连接信息，不同小区的相同柜框槽号表示这些小区的AAU共同连接同一个BBU，从而形成共AAU。AAU型号用于表示该小区连接的AAU是哪一个型号的AAU。可以理解的是，通常情况下，共AAU的多个小区连接的AAU型号是相同的。但值得注意的是，具有相同型号AAU的多个小区也有可能不是共AAU，对于哪些小区共AAU，还需要通过共AAU信息进行确定。
小区ID 带宽 频点 发射功率 AAU柜框槽号 AAU型号
123 100M F1 20w 123 AAAA
456 20M F2 40w 123 AAAA
… … … … … …
表3
在又一个例子中，采集的参数信息中包含的各小区的负荷信息，例如表4示出的。
小区ID 来水量 PRB利用率
123 9999 25％
456 1000000 50％
… … …
表4
表4中包含小区的来水量和物理资源块(physical resource block，PRB)利用率。其中，来水量表示该小区所承载的通信业务数量，PRB利用率表示该小区PRB的使用状况。其中，来水量与PRB利用率基本呈正比，即小区的来水量越高，该小区的PRB利用率也越高。显然，当某个小区来水量比较大且PRB利用率也较高时，意味着该小区的负荷也比较大。
S1102，将多个小区划分为至少一个功率共享组。
数据处理模块902根据数据采集模块901采集到的各个小区的参数信息，进行相应的特征计算。例如根据采集到的各小区的共AAU信息计算得到各个小区共AAU的特征。数据处理模块902将共AAU的多个小区划分为一组。例如，采集到的各小区的功率共享组信息可以是小区A的共AAU信息是与小区C和小区D共AAU；小区B的共AAU信息是与小区E共AAU；小区C的共AAU信息是与小区A和小区D共AAU；小区D的共AAU信息是与小区A和小区C共AAU；小区E的共AAU信息是与小区B共AAU。根据上述信息，可以将小区A、小区C和小区D划分为一个共AAU，将小区B和小区E划分为另一个共AAU。
在一个例子中，共AAU信息中可以是直接记录与该小区共AAU的其他小区的小区ID。例如表5示出的。
小区ID AAU型号 与哪些小区共AAU 是否共AAU
123 AAAA 456 是
456 AAAA 123 是
789 BBBB   否
… … … …
表5
可以看出，表5中记录了每个小区的共AAU情况，例如小区123与小区456共AAU，且与小区123连接的AAU型号为AAAA；小区456与小区123共AAU，且与小区456连接的AAU型号为AAAA；小区789不与其他任何小区共AAU，且与小区789连接的AAU型号为BBBB。并且可以确定哪些小区为共AAU小区，例如可以确定小区123和小区456是共AAU小区，小区789不是共AAU小区。
当然，功率共享组信息还可以是根据小区的位置信息以及AAU与BBU连接情况确定的。可以理解的是，若采集的参数信息中不包含小区的位置信息，则可以采用定位算法将经纬度信息添加至小区的参数信息中的MR中。在一个例子中，定位算法例如可以采用指纹定位算法、三角定位算法、小区定位算法、室内外区分算法等，本申请在此不做限定。添加了位置信息 的MR可以看作将表1和表2合并为一个表，例如表6示出的。
Figure PCTCN2020137293-appb-000006
表6
在一个例子中，例如可以通过表6中记录的各个小区的经纬度信息以及表3中记录的AAU柜框槽号(AAU与BBU连接信息)，确定出如表5种示出的各个小区的共AAU情况。例如，小区A的AAU、小区C的AAU和小区D的AAU共同连接一个BBU，以及，小区B的AAU和小区E的AAU共同连接一个BBU。由于不同物理地区可能具有相同的AAU柜框槽号，因此还可以根据各小区的经纬度信息，当位于同一块区域内不同小区具有相同的AAU柜框槽号时，则认为这些小区共AAU。根据位置信息，若确定小区A、小区C和小区D位于同一片固定区域内，小区B和小区D位于同一片固定区域内。则可以将小区A、小区C和小区D划分为一个共AAU，以及将小区B和小区E划分为另一个共AAU。例如小区A、小区C和小区D均为北京地区，小区B和小区D均为山西地区。当然若是小区A和小区D为北京地区，小区C为河南地区，则虽然小区C的AAU柜框槽号与小区A、小区D相同，但仍然仅可以将小区A和小区D划分为一个共AAU，该共AAU内不包括小区D。
值得注意的是，在一种极端的情况下，一个功率共享组中可以仅有一个小区，当然在另一种极端的情况下，可以是采集到的整个范围内的所有小区位于同一个功率共享组内。
S1103，针对每个功率共享组，计算该功率共享组内各小区的路损信息，并构建多频点模型。
首先，数据处理模块902针对根据采集到的多个小区的位置信息，确定采集的多个小区所覆盖的地理区域。并将多个小区的地理区域进行划分，划分为大小相同的方格，每个方格称为栅格。例如图12示出的，整个区域为采集的多个小区的区域，对应的每个小方格即划分出的栅格。
针对每个栅格，根据各小区的MR以及发射功率信息，计算每个栅格到各小区之间的路损信息。这里的路损既可以看做是上行链路的路损，也可以作为下行链路的路损，可以理解的是，若基站与移动台位置不变的情况下，上行链路的路损与下行链路的路损可以看做是相同的。因此通过下行信息确定出的路损信息既可以作为下行链路的路损也可作为上行链路的路损。其中，MR包含参考信号接收功率(reference signal receiving power，RSRP)信息，RSRP信息即表1中示出小区电平，单位为分贝毫瓦dBm。在一个例子中，路损信息可以通过发射功率减去小区电平得到。当然在其他例子中还可以根据实际情况考虑更多其他信息，共同计算得到路损信息，本申请在此不做限定。根据各个小区的电平以及发射功率，可以得到每个栅格到各小区之间的路损信息，例如表7示出的。
Figure PCTCN2020137293-appb-000007
表7
值得注意的是，在计算路损信息的时候，可以根据栅格的位置信息(经纬度)以及各小区的位置信息(经纬度)，确定每个栅格可以被哪几个小区覆盖到。然后在针对每个栅格，计算能够覆盖到该栅格的多个小区的路损信息。
数据处理模块902还可以根据采集到的各小区的负荷信息、各小区的覆盖面积以及各小区的发射功率信息，确定每个小区的负荷-功率函数，例如表8示出的。
Figure PCTCN2020137293-appb-000008
表8
可以看出，负荷与功率的关系可以通过线性函数表示。为方便描述，再次仅用一元线性方程表示负荷-功率函数，其中k1、k2、k3用于表示函数方程中的系数，b1、b2、b3用于表示函数方程中的常数。显然，系数以及常数在此处仅仅是示意，在其他例子中，可以通过机器学习，并参考更多的参数进行展开，本申请在此不作限定。在一些例子中，对于功率-负荷函数的确定，可以是首先通过来水量与PRB利用率计算得到小区的来水量与PRB利用率的函数，然后再通过功率与来水量的关系，将功率带入来水量与PRB利用率的函数，从而得到功率与PRB利用率的函数，即功率-负荷函数。
数据处理模块902通过机器学习的方式将采集到的数据进行计算，得到各个小区通用的负荷-功率函数。使得当输入一个新的功率时，可以得到新功率下各个小区的PRB利用率。
数据处理模块902针对至少一个功率共享组中的每个功率共享组，根据预设的配置信息、该功率共享组内各个小区的MR以及上述计算得到的该功率共享组内各小区的负荷-功率函数，构建该功率共享组的多频点模型。对于预设的配置信息，可以是预先设置在数据处理模块902内的，也可以是通过数据采集模块901采集到的。
配置信息包括可能的各种优化目标，例如优化5G的吞吐率、整体负荷更均匀、整体更节能等等目标。在又一些例子中，配置信息还可以包括不同频点的优先级，以及对应的优先级系数。可以参照表9所示。
频点 优先级 优先级系数
F1 1 0.9
F2 2 0.3
F3 3 0
… … …
表9
可以看出，不同频点具有不同的优先级。同时，对于不同的优先级在构建多频点模型时也具有不同的优先级系数。显然优先级越高的频点，其对应的优先级系数也越高。
在一个例子中，若优化目标为优化5G吞吐率时，例如在非独立组网(non-stand alone，NSA)的场景下，NR与LTE小区为共AAU小区，不同小区之间可以共用功率。为了优化NR小区的吞吐率，因此可以将LTE小区的部分功率给NR小区使用。使得LTE小区被借用功率后减小了小区的覆盖范围内，同时降低了LTE对NR的干扰；对于NR小区则提升了覆盖范围，同时也提升了小区的信噪比或信干噪比。
多频点模型的构建可以是首先构建单栅格单频点模型f，然后根据多个单栅格单频点模型f以及优先级系数，构建单栅格多频点模型F，例如可以通过F＝∑k*f计算得到。其中，k为每频点的优先级系数。最后根据多个单栅格多频点模型F构建多频点模型G，例如可以通过G＝∑F计算得到。
在一个例子中，在构建单栅格单频点模型时，可以参考每个栅格所归属的归属服务小区的信号强度、PRB利用率以及该归属服务小区的邻区的信号强度、PRB利用率得到。当然还可以考虑噪声等一些干扰因素。例如，可以通过f1＝(当前栅格归属服务小区的信号强度)/(该归属服务小区邻区的信号强度*邻区的PRB利用率+N)得到单栅格单频点模型。其中，f1为上述单栅格单频点模型f的一种可能表述形式；N表示噪声和/或其它干扰因素的一个代数形式。当然还可以针对同频小区进行计算，例如f1’＝(当前栅格归属服务小区的信号强度)/(与该归属服务小区同频的邻区的信号强度*该邻区的PRB利用率+与该归属服务小区异频但有重叠的邻区的信号强度*频域重叠系数*该邻区的PRB利用率+N)。可以理解的是，N的取值可以根据实际检测到的噪声情况进行取值。然后根据得到的多个单频点单栅格模型f1，参考不同频点的优先级系数k，通过F1＝∑k*f1得到单栅格多频点模型F1。其中，F1为上述单栅格多频点模型F的一种可能表述形式，Σ表示累加求和。最后，通过G1＝∑F1计算得到多频点模型G1。其中，G1为上述多频点模型G的一种可能表述形式。在其他例子中，对于存在多个功率共享组而言，还可结合每个功率共享组的多频点模型G1，构建整网模型Z1。其中，在采集的多个小区的范围内，可能存在多个功率共享组，而多个功率共享组构成了整网的网络环境。对于整网的调整，可以是基于多个不同的功率共享组进行宏观上的整体调整。例如可通过Z1＝∑G1，或是不同的功率共享组具有不同的优先级系数j，还可以通过Z1’＝∑j*G1计算得到整网模型。
对于构建多频点模型中的每个栅格的归属服务小区的确定，可以理解的是，当小区的发射功率变化后，每个栅格检测到的各个小区的电平也会产生变化。由于栅格到各个小区的路损信息是不变的，因此可以通过路损信息以及各小区的新发射功率计算出该栅格检测到的各小区电平信息。由于小区的电平信息可以表征该栅格检测到的小区的信号强度，因此，可以通过小区电平信息，确定该栅格的归属服务小区。其中，每个栅格检测到的能覆盖该栅格的多个小区的电平信息可以如表10所示。
Figure PCTCN2020137293-appb-000009
表10
可以看出，根据各个小区新的发射功率减去数据处理模块902计算出的每个栅格到所覆盖该栅格的各个小区的路损，可以得到该栅格检测到所覆盖该栅格的各个小区的电平，即信号强度。然后可以根据A3准侧或者S准侧，判断该栅格的归属服务小区。显然每个栅格仅归属于一个小区。其中，A3准则可以用于触发栅格同频小区或者异频小区之间的切换，当数据处理模块902检测到相邻小区的信号强度高于原小区的信号强度时，可以触发归属服务小区的切换。切换后，在该栅格位置的移动台与基站进行通信时，便可以通过新的归属服务小区进行数据以及业务传输。当然在其他例子中，还可以当数据处理模块902检测到相邻小区的信号强度高于原小区信号强度一定偏置量时，触发归属服务小区的切换。其中偏置量可以是预设的某个固定数值。S准则是用于当检测到当前小区的信号强度满足预设的要求时，则继续驻留在该小区，即归属服务小区不进行切换。在一些其他例子中，还可以根据当前小区的信号强度以及信号质量均满足预设的要求时，继续驻留在该小区。值得注意的是，对于LTE和NR可以独立计算栅格的归属服务小区，例如同一个栅格若在LTE网络中其仅归属于某一个小区；若在NR网络中，该栅格还可以归属与NR中的某一个小区。由于LTE和NR所使用的频点不同，推而广之，针对每个栅格，可以基于不同的频点，分别计算各频点下的归属服务小区。
在另一个例子中，若优化目标为负荷均衡度时，例如在非独立组网(non-stand alone，NSA)的场景下，NR与LTE小区为共AAU小区，不同小区之间可以共用功率。为了优化负荷均衡度，因此可以将LTE小区的部分功率给NR小区使用。使得LTE小区被借用功率后减小了小区的覆盖范围内，同时降低了LTE的负荷能力；对于NR小区则提升了覆盖范围，同时也提升了小区的负荷能力，使得整体负荷更加均衡。
多频点模型的构建可以是首先构建单频点模型s，然后根据多个单频点模型s以及优先级系数，构建构建多频点模型G。
在一个例子中，在构建单频点模型时，可以是首先根据各小区的发射功率信息以及负荷-功率函数，计算各小区在当前功率下的PRB利用率。显然若各小区的发射功率改变后，则各小区的PRB利用率也随之改变。由于各小区功率改变，从而导致各小区的覆盖范围也随之改变，以及归属于该小区的栅格数量也随之改变。其中栅格归属服务小区的确定可以参考表10所述的方式，在此不再赘述。然后构建多小区单频点模型，例如可以通过s1＝((Σ该频点小区的PRB利用率)*(Σ该频点小区的PRB利用率))/(该频点的小区数量*Σ(其他频点小区的PRB利用率*其他频点小区的PRB利用率))计算得到多小区单频点模型。s1为上述多小区单频点模型s的一种可能表述形式。其中，其它频点小区为除该频点以外其他频点的小区。可以理解的是，对于每个功率共享组内的单频点模型，若该功率共享组内该频点仅存在一个 小区，则单频点模型为单小区的单频点模型；当然，若该功率共享组内该频点仅存在多个小区，则单频点模型为多小区的单频点模型。最后结合各频点的优先级系数k，构建多频点模型G2，例如可以通过G2＝((Σk*s1)*(Σk*s1))/(频点个数*Σ(k*s1*s1))计算得到多频点模型G2。其中，G2为上述多频点模型G的一种可能表述形式。在其他例子中，对于存在多个功率共享组而言，还可结合每个功率共享组的多频点模型G2，构建整网模型Z2。其中，整网概念与Z1类似，为方便描述，在此不再赘述。例如可通过Z2＝∑G2，或是不同的功率共享组具有不同的优先级系数j，还可以通过Z2’＝∑j*G2计算得到整网模型。
在又一个例子中，若优化目标为单赫兹消耗的电量时，例如在非独立组网(non-stand alone，NSA)的场景下，NR与LTE小区为共AAU小区，不同小区之间可以共用功率。为了优化负荷均衡度，因此可以将LTE小区的部分功率给NR小区使用。使得LTE小区被借用功率后减小了小区的覆盖范围内，稍微提升了LTE的电量消耗；对于NR小区则提升了覆盖范围，同时也提升了小区的电量消耗。但整体电量消耗更低，使得整个网路更加节能。
多频点模型的构建可以是首先构建单小区耗电量模型l，然后根据多个单小区耗电量模型l构建单频点耗电量模型L。最后根据多个单频点耗电量模型F以及各频点的优先级系数k构建多频点模型G。
在一个例子中，在构建单小区耗电量模型时，可以是首先根据各小区的发射功率信息以及负荷-功率函数，计算各小区在当前功率下的PRB利用率。显然若各小区的发射功率改变后，则各小区的PRB利用率也随之改变。显然由于各小区功率改变，从而导致各小区的覆盖范围也随之改变，以及归属于该小区的栅格数量也随之改变。其中栅格归属服务小区的确定可以参考表10所述的方式，在此不再赘述。然后构建单小区耗电量模型例如可以通过l1＝当前小区的发射功率/(当前小区的PRB利用率*小区带宽)计算得到。其中，l1为上述单小区耗电量模型l的一种可能表述形式。之后，再构建单频点耗电量模型L，可以理解的是由于每个小区的频点可能相同也可能不同，针对相同频点的小区，可以通过L1＝Σl1计算得到单频点耗电量模型。其中，L1为上述单频点耗电量模型L的一种可能表述形式。可以理解的是，对于每个功率共享组内的单频点耗电量模型，若该功率共享组内该频点仅存在一个小区，则单频点耗电量模型为单小区的单频点耗电量模型；当然，若该功率共享组内该频点仅存在多个小区，则单频点耗电量模型为多小区的单频点耗电量模型。最后结合各单频点耗电量模型以及频点的优先级系数k，构建多频点模型G3，例如可以通过G3＝∑k*F2计算得到。其中，G3为上述多频点模型G的一种可能表述形式。在其他例子中，对于存在多个功率共享组而言，还可结合每个功率共享组的多频点模型G3，构建整网模型Z3。其中，整网概念与Z1类似，为方便描述，在此不再赘述。例如可通过Z3＝∑G3，或是不同的功率共享组具有不同的优先级系数j，还可以通过Z3’＝∑j*G3计算得到整网模型。
S1104，根据预设的配置信息以及多频点模型，对功率共享组内的多个小区进行功率分配。
功率分配模块903根据预设的配置信息以及数据处理模块902构建的每个功率共享组的多频点模型，针对每个功率共享组，将该功率共享组中的发射功率进行分配。可以理解的是，分配得到的各个小区的发射功率可以将功率共享组的最大功率全部分完，当然也可以仅将该功率共享组中的一部分功率进行分配。
其中，预设的配置信息可以包括不同AAU型号的最大发射功率以及不同AAU型号相应的功率约束。其中，功率约束可以包括最小发射功率以及与共AAU小区的功率差，例如表11所 示。
AAU型号 最大发射功率 最小发射功率(可选) 功率比范围
AAAA 100W 20W 0.5～2
BBBB 500W 10W 0.5～2
XXXX 320W 5W 0.5～4
… … … …
表11
其中，功率比范围描述了某个小区的发射功率与共AAU中其他小区的发射功率的比值。例如，某个小区连接的AAU的AAU型号为AAAA，该小区分配到的发射功率为a W，而与该小区共AAU的其他小区的发射功率为b W。功率比范围则限定了a与b之间的比值，例如在0.5-2之间，即0.5≤a/b≤2。当然上述的数值仅仅作为示例，并不作为对本申请的限定。
在又一些例子中，配置信息还可以包括不同频点的覆盖要求，例如不同频点的信号强度要大于信号强度阈值，以及不同频点的信噪比(signal-noise ratio，SNR)需要大于信噪比阈值或信干噪比(signal to interference plus noise ratio，SINR)需要大于信干噪比阈值等。当然不同频点的信号强度、信噪比或信干噪比也可以是大于或等于各自对应的阈值，本申请在此不作限定。其中，信号强度可以用RSRP表示，当然在其他例子中还可以用其他参数表示。在一个例子中，对于不同频点的覆盖要求，可以例如表12示出的。
频点 信号强度 信噪比(或信干噪比)
F1 -100 -3
F2 -105 -2
F3 -100 -3
… … …
表12
可以理解的是，将功率共享组的发射功率进行分配时，必须满足各个配置信息要求，并且还需到达配置信息中的优化目标的要求。
在一种可能实施的方式中，可以采用优化算法，求解多频点模型在该功率共享组中各个小区功率限制条件下的最优解。其中，优化算法可以是非线性优化算法、粒子群算法或启发式算法等等，本申请在此不作限定。
在一个例子中，若采用例子群算法进行计算各小区的最优功率，首先需要随机出M个粒子，每个例子包含当前功率共享组内某一个小区分配的随机功率。然后计算M个粒子的适应度函数，并保留适应度最好的粒子。根据适应度最好的粒子包含的功率方案，更新该功率共享组的功率分配方案。并重复计算M个粒子的适应度，直至适应度函数不再提升。获取当前各个频率下各个小区的功率分配方案。其中计算适应度函数，可以通过S1103中给出的不同优化目标下的多频点模型计算得到。当然若针对多个功率共享组进行整体优化分配时，则可以通过整网模型进行计算，最终得到该模型下的最优解。
本领域人员应当注意的是，本申请涉及到的配置信息，可以是人工配置，或是基于统计、机器学习或在线等功能实现动态配置，当然还可以采用其它等效的方式进行配置，本申请在此不做限定。
S1105，将分配的功率下发至各个小区对应的基站。
将S1104中计算得到的功率共享组内各个小区的最优发射功率，下发至各个小区对应的基站，以使得各基站按照对应的发射功率在相应的小区以该功率进行通信。在一个例子中，可以采用网管工具进行下发，当然在其他例子中，也可以采用人工的方式，将各小区的最优功率信息下发至各个小区对应的基站。
例如，若优化目标为优化5G吞吐率时，当通过功率分配模块903计算出各个小区的最优发射功率后，如图13所示出的一种功率分配效果示意图，通过计算得到的各小区的新发射功率，当移动台经过某个区域时，对于LTE侧该区域的栅格经过归属服务小区的重新选择后，例如选择切换至FDD1800的小区。由于LTE小区与NR小区共AAU，LTE小区将一部分功率分享给NR小区使用，因此，该栅格在LTE侧的归属服务小区进行了切换，切换到了信噪比或者吞吐率更高的小区。但是对于该区域的NR小区来讲则可以仍然驻留在原小区，因为该NR小区获得了更多的功率，其边缘的信噪比或者信干噪比要优于功率变更之前。
由于LTE小区与NR小区共享功率，但LTE整体基站密度高于NR。当调整NR功率获取增益却受到限制时，假设NR侧功率调整优先级较高，由于功率限制LTE侧的剩余功率不一定会全部利用，因此可以通过NR向LTE“借用”功率的方式，一方面提升NR吞吐率的增益，另一方面还可以降低LTE侧的干扰，提升LTE侧的感知。
又例如，若优化目标为负荷均衡度时，当前仅依赖于NR侧功率调整，没有把LTE侧的剩余功率利用起来。因此通过借用功率的方式，采用S1103中的多频点模型或整网模型进行计算，并得到最优解。使得整网在各个频点的负荷更加均衡，从而使得用户在各小区的服务质量体验更加的平稳。
再例如，若优化目标为单赫兹消耗的电量时，当前仅在单个频点内部进行节能，未利用多个频点之前的协作。因此可以通过S1103中的多频点模型或整网模型进行计算，并得到最优解。通过协调多个频点间的功率与负荷，使得整体更加节能，可以为运营商节约更多的电费，同时更加绿色环保，有利于节能减排。
本申请通过采集多个小区中各小区的参数信息，根据参数信息中的功率共享组信息将多个小区分为至少一个功率共享组。针对每个功率共享组，根据该功率共享组内各小区的MR、发射功率信息和负荷信息，构建多频点模型。根据多频点模型和预设的配置信息，将该功率共享组的发射功率进行分配，得到该功率共享组内各小区的发射功率。再将各小区的发射功率下发至对应小区的基站。可以协同优化多种制式的功率，并保证系统整体的谱效率、节能最佳或者负荷更均衡。
