The invention relates to a method for power reduction and to a communications system, in particular a radio communications system, which allows such a method. The method for data transmission in a radio communications system having a radio interface between at least one, and in particular a large number of, base stations and at least one, and in particular a large number of, subscriber stations, in which one base station can in each case be connected via a radio interface to a number of subscriber stations provides redundantly coded data which, for the connection with at least one first transmission power level, is transmitted such that data loss is accepted. A chosen portion of the coded data is omitted during the transmission, and the transmission power level is, in contrast, chosen to be higher than the first transmission power level, such that the bit error probability is sufficiently low to allow the data to be reconstructed at the receiving station.
