Resumen
The invention relates to a method for combined transmission from a transmitter comprising a plurality of transmitting antennae of one or more base stations (EB1,.., EBM) to a user receiver comprising a receiving antenna. The invention includes: reception of information from a radio channel, transmitted from the receiver (13) to an access node; precoding of information bits in a precoder (11) of the access node, in accordance with a minimum mean square error (MMSE) criterion; and assigning of a power level in order to transmit each precoded information bit via a set of transmitting antenna, wherein the power level assigned to each radio channel added to the inverse of the SINR thereof is a constant. According to the invention, a reduced power level is assigned to a weaker radio channel and a higher power level is assigned to a stronger radio channel.
