Description

一种功率控制方法、装置及计算机存储介质 技术领域
本发明涉及宽带码分多址接入通信领域，尤其涉及一种功率控制方法、装置及计算机存储介质。
背景技术
目前，宽带码分多址接入(WCDMA，Wideband Code Division Multiple Access)通信技术是第三代(3G，3rd Generation)移动通讯技术的三大主流标准之一，具有广泛的应用前景。在3G网络中，用户设备(UE，User Equipment)在进行业务的过程中，往往会发生位置移动，引起UE所处无线环境的变化，导致接收信号强度或干扰水平发生改变。在这种情况下，WCDMA空口需要借助功率控制以及切换机制来维持足够的接收信号强度或干扰水平，以保证业务的服务质量(QoS，Quality of Service)。
WCDMA空口针对物理信道进行功率控制，分为物理信道的静态功率设置以及物理信道的动态功率控制两种方式，动态功率控制技术又分为终端功率控制以及基站功率控制两类。目前终端侧的功率控制基本上都是通过与基站的交互来进行的，要么是设定物理信道功率的初始值，使得绝对值更加准确，要么是通过比较业务信道的信号干扰比(SIR，Signal to Interference Ratio)与目标值，来调整承载业务的物理信道功率的相对值，但是现有技术中并不存在同时动态调整基带功率与射频功率来合理有效地进行功率控制的技术方案。

S301：调整模块将功率配比因子除以2，并判断补偿功率因子是否大于第一阈值；
这里，第一阈值可以为25dBm。
S302a：当补偿功率因子的值大于第一阈值时，调整模块将补偿功率因子的值调整为第一阈值；
S302b：当补偿功率因子的值小于等于第一阈值时，调整模块保持补偿功率因子的值不变。
第二种情况，当前有高速业务，且配置了多条码道。此时，参见图4所示，S202可以包括：
S401：调整模块判断补偿功率因子的值是否大于第一阈值；
这里，第一阈值可以为25dBm。
S402a：当补偿功率因子的值大于第一阈值时，调整模块判断临时参考功率值是否小于第二阈值；
这里，第二阈值可以为0dBm，临时参考功率值为补偿功率因子的值与第一预设值之差，比如，临时参考功率值TempP＝ΔP-25dBm-6dBm，此时，第一预设值为31dBm。
S403a：当临时参考功率值小于等于第二阈值时，调整模块将临时参考功率值除以2，并将计算结果转换至线性域；
S404a：调整模块将转换后的计算结果分别与不同码道的功率配比因子相乘，并将补偿功率因子的值调整为第一阈值；
这里，不同码道的功率配比因子可以为βc、βd、βec、βed、βHS等，βc、βd、βec、βed、βHS分别表示信道DPCCH、专用物理数据信道(DPDCH，Dedicated Physical Data Channel)、增强专用物理控制信道(E-DPCCH，Enhanced DPCCH)、增强专用物理数据信道(E-DPDCH，Enhanced DPDCH)和高速专用物理控制信道(HS-DPCCH，High-Speed DPCCH)的功率配比因子。
进一步地，在S402a之后，上述流程还包括：
S403b：当临时参考功率值大于第二阈值时，调整模块保持不同码道的 功率配比因子不变，并将补偿功率因子的值减去第二预设值。
这里，第二预设值可可以为6dBm。
在另一实施例中，在S401之后，上述流程还包括：
S402b：当补偿功率因子的值小于等于第一阈值时，调整模块将不同码道的功率配比因子除以2，并保持补偿功率因子的值不变。
当然，调整模块还可以根据其它的控制策略，调整不同码道的功率配比因子以及补偿功率因子，本发明不做具体限定。
S203：采用调整后的不同码道的功率配比因子计算基带模块的发射功率，并采用调整后的补偿功率因子进行功率补偿。
具体来说，调整模块在获得调整后的不同码道的功率配比因子以及补偿功率因子后，将调整后的不同码道的功率配比因子发送给基带模块，将调整后的补偿功率因子发送给射频模块。基带模块收到调整后的不同码道的功率配比因子后，采用这些不同码道的功率配比因子计算基带模块的发射功率。在计算过程中，可以采用获得模块获得的基带模块的总发射功率来验证调整后的不同码道的功率配比因子。
需要说明的是，针对上述第一种情况中保持补偿功率因子的值不变的前提下，射频模块采用S201中获得的补偿功率因子进行功率补偿。
至此，UE便完成了进行功率控制的过程。
由上述可知，通过同时动态地对基带模块的功率配比以及射频模块的补偿功率进行调整，使得基带最终发送功率不受功率配比的影响、补偿功率最终稳定在射频模块的动态范围内，这样，UE的总发射功率既能符合基带模块计算出的理论功率又能满足射频性能指标的需求，进而减少UE不必要的功率消耗，提高了对功率控制的有效性。
