A METHOD FOR PROVIDING PRECODING INFORMATION IN A MULTI-USER MIMO SYSTEM

摘要

The present invention relates to a method for communicating in a network having a primary station and a plurality of secondary stations, said method comprising a step of, at the primary station, (a) configuring at least one downlink channel from the base station to a first secondary station, step (a) comprising (a1) signalling a first set of at least one parameter indicative of precoding applied to a first transmission from the base station to the first secondary station; (a2) signalling a second set of at least one parameter indicative of precoding applied to a second transmission from the base station to at least one second secondary station, wherein said step (a2) is carried out so that the second set of parameters contains less information than the first set of parameters.
