摘要： Various embodiments are disclosed which predict the channel quality indicator (CQI) in High Speed Downlink Packet Access (HSDPA). The accuracy of CQI is crucial for HSDPA performance. In some HSDPA systems the CQI may be as much as three (3) subframes stale. Accordingly, the prediction of CQI values is required in order to efficiently schedule data for transmission over the communication channel. Various embodiments disclose first order adaptive IIR filters which are significantly less complex than the finite impulse response (FIR) counterparts and achieve similar accuracy. By minimizing the mean squared error (MSE), an exact gradient descent algorithm may be used as well as two embodiment pseudolinear regression algorithms.
摘要翻译：公开了预测高速下行链路分组接入（HSDPA）中的信道质量指示符（CQI）的各种实施例。对于HSDPA性能，CQI的准确性至关重要。在一些HSDPA系统中，CQI可能多达三（3）个子帧。因此，需要CQI值的预测，以便有效地调度通过通信信道传输的数据。各种实施例公开了比有限脉冲响应（FIR）对应物复杂得多的一阶自适应IIR滤波器，并且实现类似的精度。通过最小化均方误差（MSE），可以使用精确的梯度下降算法以及两个实施例的伪线性回归算法。
