Abstract

For determining, in a distributed fashion, precoders to be applied for performing transmissions of data between a plurality of transmitters and a plurality of receivers via a global MIMO channel H of a wireless communication system, said precoders jointly forming an overall precoder V, each and every j -th transmitter perform: gathering long-term statistics of CSIT errors incurred by each one of the transmitters; obtaining short-term CSIT related data and building therefrom its own view H ( j ) of the global MIMO channel H; determining an estimate V ( j ) of the overall precoder V from the short-term CSIT related data; refining the estimate V ( j ) on the basis of the gathered long-term statistics of CSIT errors so as to obtain a refined precoder V ( j ) that is a view of the overall precoder V from the standpoint of said j -th transmitter, further on the basis of its own view H ( j ) of the global MIMO channel H , and further on the basis of a figure of merit representative of performance of said transmissions via the global MIMO channel H.
