A method, implemented by a sender node of a radiofrequency
wireless communication
system, said method comprising: sending to one or more
receiver node, or receiving from said one or more
receiver node, a signaling indicating an initialization of a procedure to insert in a plurality of data packets reference signals according to a plurality of reference
signal patterns having respectively a plurality of distinct values of at least one parameter; inserting reference signals according to a first reference
signal pattern in a first set of data packets ; sending, through a shared channel of said radiofrequency
wireless communication
system, said first set of data packets to said one or more
receiver node of said radiofrequency
wireless communication
system ; inserting reference signals according to a second reference
signal pattern in a second set of data packets, values of said at least one parameter being different between the first reference signal pattern and the second reference signal pattern ; sending, through said shared channel, said second set of data packets to said one or more receiver node.
