Abstract
For power control in a wireless communication system, a node comprises means for obtaining power of signals received over a wireless signal channel and a power control signal unit. The power control signal unit (21) provides power control signals intended for the power control over the channel. A warper unit warps the power control signals by a first filter. A quantizer quantizes the warped power control signals, which are transferred to another node in the wireless communication system. The receiving node comprises a dewarper, dewarping the received signals by a second filter. The power control of the wireless signal channel is performed based on the dewarped power control signal. The filters are linear filters arranged for reducing an influence of quantization. The second filter is an inverse filter with respect to the first filter. The filters are preferably adapted by adaptors.
