Description

资源调整方法、装置、芯片及计算机程序 技术领域
本申请涉及无线网络技术，特别涉及资源调整方法、装置、芯片及计算机程序。
背景技术
电磁波吸收比值(SAR，Specific Absorption Rate)是衡量终端设备对人体电磁辐射强度的指标参量，标准上对SAR值有着严格的指标要求，终端设备通常不能超过指标要求。
通常来说，终端设备的发射功率越高，SAR值越大，采用的上行占比(上行时隙占比)越高，SAR值越大。
在实际应用中，某些终端设备会同时支持长期演进(LTE，Long Term Evolution)和新空口(NR，New Radio)两种制式，这种终端设备可称为EN-DC终端设备，LTE和NR处于同时工作状态。EN-DC终端设备的功率等级取决于总发射功率。
一种典型的EN-DC终端设备为LTE频分双工(FDD，Frequency Division Duplexing)+NR时分双工(TDD，Time Division Duplexing)终端设备。LTE FDD上行处于一直发送的状态，典型的LTE终端设备当发射功率达到或超过23dBm时，其SAR即会面临超标的风险，那么对于LTE FDD+NR TDD终端设备，如何避免SAR超标，将是一个亟待解决的问题，但目前还没有一种有效的解决方式。

图2为本申请实施例提供的资源调整方法的第一示意性流程图。如图2所示，包括以下具体实现方式。
在201中，获取终端设备的LTE发射功率，终端设备为LTE FDD+NR TDD终端设备。
在202中，根据获取到的LTE发射功率确定出在SAR指标未超标的情况下的最大NR等效电场强度。
在203中，基于最大NR等效电场强度调整终端设备的NR发射功率和/或NR 上行占比。
LTE FDD+NR TDD终端设备的总发射功率通常为26dBm。
对于LTE FDD+NR TDD终端设备，由于LTE和NR处于不同频段，可能采用不同的天线，因此SAR值辐射上LTE和NR不具有等效性，即同样LTE和NR的发射功率带来的SAR值是不一样的。
另外，对于LTE，当发射功率大于或等于23dBm时，即使NR不工作，其SAR仍面临超标的风险，因此为避免SAR超标，总功率的分配通常需要满足以下条件：LTE发射功率≤23dBm；LTE发射功率与NR发射功率之和≤总发射功率。
本实施例所述的资源调整方法中，可首先获取终端设备的LTE发射功率，可由上行功控得到LTE发射功率。之后，可根据获取到的LTE发射功率确定出在SAR指标未超标的情况下的最大NR等效电场强度。
优选地，可按照现有方式获取终端设备的LTE发射功率对应的电场强度EP LTE，之后，可根据预先设定的EP LTE、SAR指标对应的电场强度E SAR以及NR等效电场强度之间的限定条件，确定出取值最大的NR等效电场强度，作为所需的最大NR等效电场强度。
限定条件可为：EP LTE+EP NR*Duty NR≤E SAR。
其中，EP NR表示NR发射功率对应的电场强度，Duty NR表示NR上行占比，EP NR*Duty NR表示NR等效电场强度。
由于SAR指标的取值是定义好的，那么可获取到SAR指标对应的电场强度E SAR，进而根据上述限定条件，可确定出取值最大的NR等效电场强度EP NR*Duty NR，将其作为所需的最大NR等效电场强度。
或者，在根据终端设备的LTE发射功率确定出在SAR指标未超标的情况下的最大NR等效电场强度之前，可先根据上述限定条件，分别确定出不同的LTE发射功率对应的最大NR等效电场强度，并将确定出的对应关系记录到第一存储表中。这样，当需要根据终端设备的LTE发射功率确定出在SAR指标未超标的情况下的最大NR等效电场强度时，可通过查询第一存储表，确定出终端设备的LTE发射功率对应的最大NR等效电场强度。
不同的LTE发射功率，理论上包括LTE发射功率的所有可能的取值，但考虑到占用的存储空间大小以及查表速度等，通常会选取一些典型的LTE发射功率的取值，将其与对应的最大NR等效电场强度之间的对应关系记录到第一存储表中，如表一所示。
LTE发射功率 最大NR等效电场强度
23 E 23
22 E 22
… …
1 E 1
0 E 0
表一LTE发射功率与最大NR等效电场强度之间的对应关系
如表一所示，可分别确定出LTE发射功率为23dBm、22dBm、…、1dBm、0dBm时对应的最大NR等效电场强度。
当根据终端设备的LTE发射功率查询第一存储表时，终端设备的LTE发射功率可能并不存在于第一存储表中，那么可选择第一存储表中记录的各LTE发射功率中与终端设备的LTE发射功率取值最为接近的一个，将该LTE发射功率对应的最大NR等效电场强度作为终端设备的LTE发射功率对应的最大NR等效电场强度。
进一步地，针对第一存储表中的每个最大NR等效电场强度，可分别生成对应的第二存储表，第二存储表中记录有不同的NR发射功率与对应的最大NR上行占比之间的对应关系，每个NR发射功率对应的电场强度与对应的最大NR上行占比的乘积等于该最大NR等效电场强度。
比如，针对表一中所示的E 22，可生成如表二所示的第二存储表。
NR发射功率 最大NR上行占比
26 Duty 26
25 Duty 25
… …
1 Duty 1
0 Duty 0
表二NR发射功率与最大NR上行占比之间的对应关系
不同的NR发射功率，理论上包括NR发射功率的所有可能的取值，但考虑到 占用的存储空间大小以及查表速度等，通常会选取一些典型的NR发射功率的取值，如表二中所示的26dBm、25dBm等，将其与对应的最大NR上行占比之间的对应关系记录到第二存储表中。
根据NR等效电场强度的计算方式EP NR*Duty NR，表二中，以NR发射功率为26dBm为例，对应的电场强度(EP NR)与对应的最大NR上行占比(Duty 26)的乘积需要等于E 22，同样地，NR发射功率为25dBm时对应的电场强度与Duty 25的乘积也需要等于E 22，其它不再赘述。
在根据终端设备的LTE发射功率确定出在SAR指标未超标的情况下的最大NR等效电场强度之后，可基于该最大NR等效电场强度调整终端设备的NR发射功率和/或NR上行占比。具体地，可首先确定出该最大NR等效电场强度对应的第二存储表，为便于表述，将确定出的第二存储表称为第二存储表x，之后，可基于第二存储表x调整终端设备的NR发射功率和/或NR上行占比。
另外，在基于第二存储表x调整终端设备的NR发射功率和/或NR上行占比之前，还可先确定是否符合调整条件，若是，则调整终端设备的NR发射功率和/或NR上行占比。
可获取终端设备的NR发射功率，并通过查询第二存储表x，确定出终端设备的NR发射功率对应的最大NR上行占比，之后，可获取终端设备的NR上行占比，并将终端设备的NR上行占比与查询到的终端设备的NR发射功率对应的最大NR上行占比进行比较，若终端设备的NR上行占比大于终端设备的NR发射功率对应的最大NR上行占比，则可确定符合调整条件。
在确定符合调整条件之后，可对终端设备的NR发射功率和/或NR上行占比进行调整。
调整方式包括但不限于：
1)通过查询第二存储表x，确定出终端设备的NR上行占比对应的NR发射功率，将终端设备的NR发射功率调整为终端设备的NR上行占比对应的NR发射功率；
2)通过查询第二存储表x，确定出终端设备的NR发射功率对应的最大NR上行占比，将终端设备的NR上行占比调整为终端设备的NR发射功率对应的最大NR上行占比。
在查询第二存储表x时，终端设备的NR上行占比可能并不存在于第二存储表x中，那么可选择第二存储表x中记录的各NR上行占比中与终端设备的NR上行占 比取值最为接近的一个，将该NR上行占比对应的NR发射功率作为终端设备的NR上行占比对应的NR发射功率。
同样地，在查询第二存储表x时，终端设备的NR发射功率可能并不存在于第二存储表x中，那么可选择第二存储表x中记录的各NR发射功率中与终端设备的NR发射功率取值最为接近的一个，将该NR发射功率对应的最大NR上行占比作为终端设备的NR发射功率对应的最大NR上行占比。
在对终端设备的NR发射功率进行调整之后，若终端设备的NR发射功率小于预定阈值，为保证工作质量，可断开NR连接，预定阈值的具体取值可根据实际需要而定。
基于上述介绍，图3为本申请实施例提供的资源调整方法的第二示意性流程图。如图3所示，包括以下具体实现方式。
在301中，获取终端设备的LTE发射功率，终端设备为LTE FDD+NR TDD终端设备。
在302中，通过查询第一存储表，确定出终端设备的LTE发射功率对应的最大NR等效电场强度。
可预先根据限定条件EP LTE+EP NR*Duty NR≤E SAR，分别确定出不同的LTE发射功率对应的最大NR等效电场强度，并将确定出的对应关系记录到第一存储表中。
其中，EP LTE表示LTE发射功率对应的电场强度，E SAR表示SAR指标对应的电场强度，EP NR表示NR发射功率对应的电场强度，Duty NR表示NR上行占比，EP NR*Duty NR表示NR等效电场强度。
在303中，确定出终端设备的LTE发射功率对应的最大NR等效电场强度对应的第二存储表。
针对第一存储表中的每个最大NR等效电场强度，可分别生成对应的第二存储表中，第二存储表中记录有不同的NR发射功率与对应的最大NR上行占比之间的对应关系，每个NR发射功率对应的电场强度与对应的最大NR上行占比的乘积等于该最大NR等效电场强度。
在304中，获取终端设备的NR发射功率，通过查询确定出的第二存储表，确定出终端设备的NR发射功率对应的最大NR上行占比。
在305中，获取终端设备的NR上行占比，将终端设备的NR上行占比与终端设备的NR发射功率对应的最大NR上行占比进行比较。
在306中，若终端设备的NR上行占比大于终端设备的NR发射功率对应的最 大NR上行占比，则通过查询确定出的第二存储表，确定出终端设备的NR上行占比对应的NR发射功率，将终端设备的NR发射功率调整为终端设备的NR上行占比对应的NR发射功率。
在307中，若调整后的终端设备的NR发射功率小于预定阈值，断开NR连接。
需要说明的是，对于前述的各方法实施例，为了简单描述，将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本申请并不受所描述的动作顺序的限制，因为依据本申请，某些步骤可以采用其它顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本申请所必须的。
在上述实施例中，对各实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其它实施例中的相关描述。
总之，采用本申请所述方案，可通过对终端设备的NR发射功率和/或NR上行占比进行调整，降低SAR值，从而避免了终端设备的SAR超标。
