具体实施方式
本申请实施例提供了一种载波的处理的方法、基带单元及存储介质，旨在为终端设备选取出合适的载波，并且还能够在载波提供相同业务的情形中，降低RU的能耗。
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清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含。在本申请中，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b或c中的至少一项(个)，可以表示：a，b，c，a和b，a和c，b和c或a和b和c，其中a、b和c可以是单个，也可以是多个。值得注意的是，“至少一项(个)”还可以解释成“一项(个)或多项(个)”。
随着无线网络的发展，各制式各频段的载波也在逐步增加，不同形式的载波选择为用户提供了不同的业务。在相关技术中，基站通过判断所覆盖的各个小区的负载大小，并进行各个小区间的负载信息交互后，以此选择出负载较低的载波，进而将终端设备从负载较高的小区切换至负载较低的小区驻留。如图1所示，为现有方案提供的一种载波选择的示意图。从图1可以看出，基站覆盖小区A和小区B，并通过至少一个载波为驻留在小区A中的终端设备、以及为驻留在小区B中的终端设备提供业务服务。而且，从图1中的a部分可知，小区A中驻留有5个终端设备(例如：终端设备1～5)，负载较高；小区B中仅驻留一个终端设备(如终端设备6)，负载较低，剩余较多的网络资源。因此，为了能够最大化地利用网络资源，基站通过判断a部分中的小区A的负载大小和小区B的负载大小后，选择出负载较小的小区B所对应的载波，为驻留在小区A中的终端设备提供业务服务。这样，基站便可以将原先驻留在小区A中的至少一个终端设备(如：终端设备4、终端设备5)，从小区A切换至在小区B中驻留，进而通过小区B所对应的载波为终端设备4、终端设备5提供业务服务，具体可以参照图1中的b部分进行理解。也就是说，在图1所示的载波选择中，基站采用移动负载均衡的方式，协调位于同频系统或异频系统的各个小区之间的负载分布，以选取出载波，进而通过选取后的载波为终端设备提供业务服务。此外，需说明，上述所描述的终端设备可以包括但不限于：手持终端、笔记本电脑、用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handheld)、膝上型电脑(laptop computer)或是其他可以接入网络的设备，此处不做限定说明。
然而，无线网络往往由多个载波覆盖同一片区域，而多个载波之间的频谱效率差异、射频单元(radio unit，RU)的个体差异等，导致不同的载波在提供相同业务时所需能耗也存在差异，进而影响载波的选择。参阅图2，为本申请实施例提供的一种不同载波的负载与射频单元的能耗之间的关系示意图。从图2可知，不同载波在相同的负载增长下，射频单元的能耗增长幅度也存在差异。例如，图2所示的2100M的载波1，对应的负载能耗模型为y＝0.2504x+0.092，其中，x为载波的负载，y为RU的能耗；1800M的载波2对应的负载能耗模型为y＝0.1823x+0.1153。即便载波1和载波2的带宽一致，并且在频谱效率一致的情况下，该载波1所对应的能耗增长与该载波2所对应的能耗增长也相差0.0681kw/h。那么，如果该载波1和载波2均传输20％的单位业务数据量，相应的能耗增长则会相差30％以上。
由此看来，不同载波在提供相同业务时所需能耗也会存在差异，进而会影响载波的选择。因此，在上述图1所示的现有方案中，仅仅考虑负载情况来选取载波，难以选取出较为合适的载波为终端设备提供业务服务，并且也不利于节省基站的网络资源的消耗。
为了能够解决上述的问题，本申请通过各个载波的历史负载信息和射频单元的历史能耗信息构建负载能耗模型，以显性地表达出各个载波的负载与射频单元的能耗之间的关系。这样，通过负载能耗模型，从能耗较优的角度为终端设备选择合理的载波提供业务服务，进而降低基站的网络资源的消耗。具体地，图3示出了本申请实施例提供的一种系统框架示意图。该系统可以包括至少一个基带单元(base band unit，BBU)和至少一个射频单元RU， 图3以包括一个BBU101和一个RU102为例说明。需说明，BBU101与RU102可以物理上设置在一起，也可以物理上分离设置，即分布式网络设备。BBU101和RU102之间的接口可为光接口，两者之间可通过光纤传输数据。
需说明，上述的RU102主要用于向BBU101发送能耗信息，使得BBU101能够构建负载能耗模型。另外，上述的BBU101主要用于进行基带信号处理，对网络设备进行控制等。对基带信号处理包括信道编码，复用，调制，扩频、对载波的功率进行限幅、取消功率的限幅等。BBU101通过配置RU102与至少一个载波之间的映射关系，进而可将RU102的历史能耗信息、以及与该RU102存在映射关系的各个载波的历史负载信息作为训练数据，以此构建出负载能耗模型。这样，BBU101在获取目标终端设备发送的信号质量测量报告后，便可以根据该信号质量测量报告确定出第一载波集合、以及该第一载波集合中每个第一载波对应的第一频谱效率；进而根据每个第一载波对应的第一频谱效率和上述负载能耗模型得到的第一关系，确定出每个第一载波对应的第一能耗增长系数；然后，根据每个第一载波对应的第一能耗增长系数选择目标载波，指示目标终端设备能够驻留至该目标载波对应的小区。示例性地，BBU101可以由一个或多个单板构成，多个单板可以共同支持单一接入制式的无线接入网，例如长期演进(long term evolution，LTE)；也可以支持NR系统、或者应用于LTE系统与NR系统之间，此处不做限定说明。
基于上述内容，图4示出了本申请实施例提供的一种载波的处理方法的流程示意图。图4中的基带单元可以是上述图3中的BBU101，射频单元也可以是上述图3中的RU102，具体此处不做限定说明。如图4所示，该载波的处理方法可以包括：
401、基带单元获取目标终端设备上报的信号质量测量报告。
该示例中，测量是检测信号质量和切换驻留在小区的终端设备的重要依据。所描述的信号质量测量报告可以反映出载波的信号质量、信号强度、接收码功率等信息；还可以反映出载波的丢包率、拥塞率等其他信息。因此，基带单元欲想获知可以为目标终端设备提供业务的候选载波、以及每一个候选载波对应的频谱效率，那么可以向目标终端设备发送测量报告请求，以使得该目标终端设备对载波进行信号质量、信号强度等测量。在目标终端设备测量得到相应的信号质量测量报告后，便可以将该信号质量测量报告上报至基带单元。这样，基带单元便可以获取到该信号质量测量报告。
可选的，在一些示例中，在基带单元获取信号质量测量报告之前，还可以对其覆盖区域内的大量终端设备进行预处理，以便筛选出能够执行步骤401-404的目标终端设备。具体地，在基带单元获取目标终端设备上报的测量报告之前，基带单元从至少一个终端设备中选取目标终端设备，目标终端设备的运行速率大于或等于预设阈值。换言之，基带单元可以通过判断至少一个终端设备的运行速率是否大于或等于预设阈值；若至少一个终端设备中存在运行速率大于或等于预设阈值的终端设备，那么基带单元可以将运行速率大于或等于预设阈值的终端设备选取为目标终端设备，摒弃掉运行速率较差的终端设备，为后续选取合适的载波奠定了基础。
402、基带单元基于信号质量测量报告确定第一载波集合、以及第一载波集合中每个第一载波对应的第一频谱效率，第一载波为目标终端设备可接入的载波。
该示例中，由于信号质量测量报告可以反映出载波的信号质量、信号强度等信息，那么基带单元可以根据该信号质量测量报告从大量的载波中确定出第一载波集合。所描述的第一载波集合中的每一个第一载波均可以理解为，该目标终端设备可选择接入的载波。
此外，频谱效率又称为频带利用率，可以理解成单位带宽传输频道上每秒可传输的比特数，能够用于衡量通信系统有效性的重要指标。因此，基带单元在基于信号质量测量报告确定出第一载波集合后，还可以进一步地基于该信号质量测量报告确定出每个第一载波对应的第一频谱效率，即每个第一频谱效率可以反映出在每个第一载波上传输的单位数据所需的无线资源。所描述的无线资源可以是时域资源和/或频域资源，此处不做限定说明。
403、基带单元基于第一关系和每个第一载波对应的第一频谱效率，确定每个第一载波对应的第一能耗增长系数，其中，第一关系用于指示射频单元RU的能耗与载波的负载之间的对应关系，载波为RU对应的载波，第一能耗增长系数用于反映物理资源增长所对应的能耗增长速度。
该示例中，第一关系能够指示出RU的能耗与载波的负载之间的对应关系。所描述的载波为该RU对应的载波，也理解成该RU承载的载波，或者与该RU存在映射关系的所有的载波，也即该RU将信号发射出去时，能够选择使用的所有的载波。另外，所描述的载波的负载是指载波的下行负载。例如，在LTE系统中，载波的下行负载可以是载波的实际物理资源块(physical resource block，PRB)与最大可用PRB的比值。在通用移动通信系统(universal mobile telecommunications system，UMTS)系统中，载波的下行负载可以是载波实际功率与最大允许功率的比值。在5G新空口(new radio，NR)中，载波的下行负载可以是待测小区的实际物理资源块(physical resource block，PRB)与最大可用PRB的比值，也可以是载波实际功率与最大允许功率的比值。
上述所描述的第一关系是基于训练后的负载能耗模型得到的，训练后的负载能耗模型是以RU的历史能耗信息、载波的历史负载信息作为训练数据，对负载能耗模型进行迭代训练后获取的模型，负载能耗模型的输出用于指示RU的能耗与载波的负载之间的关系。具体地，图5示出了本申请实施例提供的一种构建负载能耗模型的流程示意图。从图5可知，负载能耗模型的构建过程可以参照如下内容进行理解：
首先，基带单元在训练负载能耗模型之前，可以先根据配置信息构建载波与RU之间的映射关系。然后，基带单元根据该映射关系，可以周期性地收集基站所覆盖的各个小区对应的各个载波的历史负载信息、以及各个RU的历史能耗信息，以此作为初始样本数据。需说明，所描述的配置信息可以包括但不限于各个载波的发射功率、各个载波对应的各个小区所部署的扇区信息等，此处不做限定说明。
然后，在将RU作为信息整合指标的基础上，基带单元根据所构建的映射关系，将各个载波的历史负载信息、以及各个RU的历史能耗信息重新整合。这样，最终整合得到的各个训练样本数据，则是基于各个RU在不同时段的一个历史信息样本。也就是理解成，针对任意一个RU，将该RU的历史能耗信息、以及与该RU存在映射关系的所有载波的历史负载信息作为一个训练样本数据，然后针对不同时段的训练样本数据，则可以得到该RU相应的训练样本数据集。例如，以图3中的RU102为例，若与该RU102存在映射关系的载波包括载 波1、载波3以及载波5，那么可以将该RU102的历史能耗信息、以及载波1的历史负载信息、载波3的历史负载信息以及载波5的历史负载信息，在不同时段上的信息作为一个训练样本数据，具体此处不做限定。另外，除了针对不同时段以外，也可以以不同的时间点等整合训练样本数据，此处不做限定说明。这样，基带单元通过不同时段的RU的历史能耗信息、以及相应的所有载波的历史负载信息，便可以得到针对该RU的大量训练样本了。
最后，基带单元可以利用简单线性回归算法或者机器学习等方式，为每个RU训练各自的负载能耗模型，进而使得训练后的负载能耗模型的输出可以指示出RU的能耗与载波的负载之间的关系，即可以得到上述的第一关系。需说明，该第一关系可以通过线性表达式，或者非线性表达式来体现，具体视情况而定。
因此，基带单元在得到每个第一载波对应的第一频谱效率后，可以结合基于训练后的负载能耗模型得到的第一关系，确定出每个第一载波分别对应的第一能耗增长系数。这样，基带单元便可以获知每个第一载波的负载增加一个单位量时，该RU相应增加的单位能耗量，从能耗较优的角度为后续选取目标载波提供了方向。需说明，上述所描述的每个第一载波的第一能耗增长系数能够反映出在相应的第一载波上的物理资源增长所对应的能耗增长速度，即在第一载波上的单位物理资源的能耗增长。譬如说，在每个第一载波上每增加一个单位量的负载时，该RU增加的单位能耗量。
可选的，在一些示例中，基带单元根据第一关系和每个第一载波对应的第一频谱效率，确定每个第一载波对应的第一能耗增长系数，具体可以通过以下方式来确定：基带单元对第一关系进行求导计算，得到能耗增长速度；然后，基带单元根据能耗增长速度和每个第一载波对应的第一频谱效率，确定每个第一载波对应的第一能耗增长系数。
从上述图5可知，第一关系反映出RU的能耗与载波的负载之间的对应关系，也可以理解成以载波的负载为自变量、以该RU的能耗为因变量构建的负载能耗模型的输出。其具体可以采用线性表达式，或者非线性表达式来体现。这样，基带单元在得知第一关系后，通过对该第一关系进行求导计算，进而得到相应的能耗增长速度。然后，基带单元将能耗增长速度和每个第一载波对应的第一频谱效率，按照下述公式一进行计算，便可以得到每个第一载波对应的第一能耗增长系数了。需说明，上述的公式一为：
Figure PCTCN2021080421-appb-000001
其中，L为第一载波对应的第一能耗增长系数，K为能耗增长速度，A为第一载波对应的第一频谱效率。
404、基带单元基于每个第一载波对应的第一能耗增长系数，选取目标载波，指示目标终端设备驻留至目标载波对应的小区。
该示例中，基带单元得到每个第一载波对应的第一能耗增长系数后，便可以选取出目标载波，进而通过通知消息等方式，指示目标终端设备能够从当前驻留的小区切换至该目标载波对应的小区。这样，基带单元便可以基于该目标载波为目标终端设备提供业务服务。具体地，基带单元可以从每个第一载波对应的第一能耗增长系数中，确定最小能耗增长系数；然后将最小能耗增长系数对应的第一载波选取为目标载波。
在本申请实施例中，在考虑载波负载的基础上，结合RU的能耗情况构建出负载能耗模型，以通过该负载能耗模型得到的第一关系。这样，基带单元在获取目标终端设备上报的信号质量测量报告后，能够基于该信号质量测量报告确定出每个第一载波对应的第一频谱效率，然后再根据前述的第一关系和每个第一载波对应的第一频谱效率确定出每个第一载 波对应的第一能耗增长系数，进而选取出在提供相同业务服务时，给RU带来能耗较小的目标载波。不仅实现了为终端设备选取合适的载波，而且还能够在载波提供相同业务的情形中，降低RU的能耗。
上述主要从能耗较优的角度描述了选取目标载波，以通过目标载波为终端设备提供业务服务的方案。下面将从能耗较优的角度描述合理地分配多个载波中传输的数据量，为终端设备提供业务的方案。具体可以参阅图6，为本申请实施例中提供的另一种载波的处理方法的流程示意图。从图6可以看出，该载波的处理方法可以包括：
601、基带单元获取目标终端设备上报的信号质量测量报告。
602、基带单元基于信号质量测量报告确定第一载波集合。
该示例中，步骤601-602可以参照上述图4中的步骤401-402进行理解，此处不做赘述说明。
603、基带单元基于调度信息确定第二载波集合中每个第二载波的第二频谱效率，第二载波为在第一载波集合中的、且与目标终端设备已建立连接的载波。
该示例中，由于信号质量测量报告可以反映出目标终端设备可以接入的载波的信号质量、信号强度等信息，因此基带单元在获取得到该信号质量测量报告后，还可以基于该信号质量测量报告确定出调度信息，即从信号质量测量报告中确定出该目标终端设备可以接入的载波所对应的实时的信号质量情况，得到较为准确的信号质量、信号强度等信息。然后，基带单元可以根据历史信令等，从第一载波集合中选取第二载波集合，即从目标终端设备可以接入的第一载波集合中选取出已经与该目标终端设备建立起连接的第二载波。这样，基带单元便可以基于该调度信息确定出该第二载波集合中每个第二载波的第二频谱效率了。
604、基带单元基于第一关系和每个第二载波的第二频谱效率，确定每个第二载波的第二能耗增长系数。
从上述图5可知，第一关系能够指示出RU的能耗与载波的负载之间的对应关系。因此，基带单元在得到每个第二载波的第二频谱效率后，可以结合基于训练后的负载能耗模型得到的第一关系，确定出每个第二载波分别对应的第二能耗增长系数。具体地，基带单元可以对该第一关系进行求导计算，得到相应的能耗增长速度；然后，将该能耗增长速度分别除以每个第二载波对应的第二频谱效率，即可得到每个第二载波对应的能耗增长系数了，具体也可以参照上述图4中步骤403的公式一进行理解，此处不做赘述。
需说明，所描述的每个第二载波的第二能耗增长系数可以反映出在每个第二载波上的物理资源增长所对应的能耗增长速度，即在第二载波上的单位物理资源的能耗增长。也可以理解成，针对每个第二载波，每增加一个单位量的负载时，该RU增加的单位能耗量。
605、基带单元基于每个第二载波的第二能耗增长系数和下行调度数据总量，得到各个第二载波调度的下行调度数据量。
该示例中，基带单元在确定出每个第二载波的第二能耗增长系数后，可以通过该第二能耗增长系数，从下行调度数据总量中确定出每个第二载波需要调度的下行调度数据量。不仅实现了在目标终端设备已经与多个第二载波建立连接的基础上，能够通过各个第二载 波的第二能耗增长系数，将下行调度数据总量合理地分配在每个第二载波上；而且还进一步地降低了整体能耗。
可选的，在一些示例中，基带单元根据每个第二载波的第二能耗增长系数和下行调度数据总量，得到各个第二载波调度的下行调度数据量。具体可以通过以下方式来实现，即：基带单元根据每个第二载波的第二能耗增长系数确定各个第二载波的分配权重，各个第二载波的分配权重用于反映下行调度数据总量在每个第二载波上的分流比例；然后，基于每个第二载波的分配权重和下行调度数据总量，确定各个第二载波调度的下行调度数据量。
该示例中，由于每个第二载波的第二能耗增长系数反映出在第二载波上的单位物理资源的能耗增长。因此，为了能够使得第二能耗增长系数较大的第二载波可以传输较少的下行数据，第二能耗增长系数较小的第二载波可以传输多一些的下行数据，基带单元可以对第二能耗增长系数较大的第二载波分配小一些的权重，使得第二能耗增长系数较大的第二载波的负载减小；以及，基带单元对第二能耗增长系数较小的第二载波分配大一些的权重，使得能耗增长系数较小的第二载波的负载可以相应的增加。基于此，基带单元能够根据每个第二载波的第二能耗增长系数确定出每个第二载波的分配权重，进而由每个第二载波的分配权重分别指示出下行调度数据总量被分配在每个第二载波上的分流比例。这样，基带单元在得到需要为该目标终端设备传输的下行调度数据总量后，便可以根据每个第二载波的分配权重，分别确定出每个第二载波需要调度的下行调度数据量了。
具体地，确定各个第二载波的分配权重可以遵循：增大第二能耗增长系数较小的第二载波的分配权重，减小第二能耗增长系数较大的第二载波的分配权重。举例来说，以图3中的RU102为例，假设该RU102承载的载波包括载波1、载波2、载波3、载波4以及载波5，其中，与目标终端设备已经建立连接的载波为载波1、载波3、载波4。那么，如果基带单元在确定出载波1的第二能耗增长系数、载波3的第二能耗增长系数以及载波4的第二能耗增长系数的比值为1:2:3，那么基带单元可以将载波1、载波3以及载波4的分配权重设定为3:2:1等。又或者，也可以设为其他的分配权重，比如1:0:0，即可以将全部的下行调度数据量分配在第二能耗增长系数最小的第二载波(即载波1)上。可以理解的是，在实际应用中，该分配权重还可以视具体情况确定为其他的权重，此处不做限定说明。
本申请实施例中，基带单元在确定出每个第二载波的第二能耗增长系数后，可以通过各个第二能耗增长系数，从下行调度数据总量中确定出每个第二载波需要调度的下行调度数据量。不仅实现了在目标终端设备已经与多个第二载波建立连接的基础上，能够通过各个第二载波的第二能耗增长系数，将下行调度数据总量合理地分配在每个第二载波上；而且还进一步地降低了RU的整体能耗。
可以理解的是，上述基带单元为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的模块及算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。
从硬件结构上来描述，图3至图6中的基带单元可以由一个实体设备实现，也可以由多个实体设备共同实现，还可以是一个实体设备内的一个逻辑功能模块，本申请实施例对此不作具体限定。

通信线路704可以包括任意数量的互联的总线和桥，通信线路704将包括由处理器702代表的一个或多个处理器702和存储器703代表的存储器的各种电路链接在一起。通信线路704还可以将诸如外围设备、稳压器和功率管理电路等之类的各种其他电路链接在一起，这些都是本领域所公知的，因此，本申请不再对其进行进一步描述。
