摘要 |
The present invention relates to a method for communicating from a primary station with an array of transmit antennas to a secondary station on a downlink channel, said method comprising steps of, at the primary station, (a) configuring the downlink channel, step (a) being subdivided into steps of:5 (a2) computing a precoding to be applied during a corresponding transmission from the primary station to the secondary station for each of an array of transmit antennas; (a3) applying a reversible transform to the precoding, thus ascertaining a set of precoding coefficients substantially representative of the precoding in a transform 10 domain; (a4) computing a set of parameters comprising at least one parameter, said parameter being substantially representative of the coefficients obtained at step (a3); (a5) signaling the set of parameters to the secondary station;15 (b) transmitting data to the secondarystation substantially according to the precoding computed at step (a2). |
