Abstract

Method for reducing energy consumption in a digital communication system (14) in idle mode, including the steps of: estimating a received signal quality value (52), prior to decoding of the received message packet, skipping the convolutional decoding and hard sample-to-bit converting of the samples (54), when received signal quality value is within a predetermined valid range, thereby producing a plurality of estimated bits, and decoding (56) the estimated bits by utilizing predetermined decoding data, when received signal quality is outside a predetermined valid range, thereby producing decoded bits.
