Abstract
A method to implement a Multiple Input Multiple Output transmission mode In the method of the invention, said MIMO transmission mode comprises using a certain number of antennas in a user equipment and a given number of antennas in a radio access node for the communication between said user equipment and said radio access node, said communication carried out by means of a communication channel, said communication channel represented by a channel matrix. The method of the invention is characterized in that it comprises uncorrelating at least part of the coefficients of said channel matrix when said communication channel is degenerate by making use of at least one additional antenna in each of said radio access node and said user equipment in order to change the radiation pattern associated to transmission layers of said communication enabling the use of an enhanced MIMO transmission mode.
