    • Techniques and systems for channel prediction in wireless networks. A base station receives a succession of channel indicators from each of a plurality of mobile units, each channel indicator being received from each mobile unit once per timeslot. A channel predictor uses the channel indicators to generate a channel condition prediction for each mobile unit, the channel condition prediction being based on a balanced estimate using the most recent channel condition indicator and the mean of the succession of channel indicators. A weight is computed based on a gradient of the succession channel indicator values and used to assign relative emphasis to the most recent channel condition indicator and the mean channel condition indicator in order to give greater emphasis to the most recent indicator during slowly changing conditions and greater emphasis to the mean indicator during rapidly changing conditions.
    • 无线网络中信道预测的技术和系统。 基站从多个移动单元中的每一个接收连续的信道指示符,每个时隙从每个移动单元接收每个信道指示符。 信道预测器使用信道指示符为每个移动单元生成信道条件预测,信道条件预测基于使用最新信道条件指示符的平衡估计和信道指示符的连续平均值。 基于连续信道指示符值的梯度来计算权重,并且用于将相对强调分配给最近的信道条件指示符和平均信道条件指示符,以便在缓慢变化的条件下更加强调最近的指示符和更大的权重 在快速变化的条件下强调平均指标。
