Abstract: A communication method is implemented in a transmission system comprising an emitter and a set of receivers. The method comprises, for at least one time-frequency resource, receiving, from each of the receivers, at least one piece of information relating to a technique for acquiring knowledge of the transmit channel. At least one of said receivers is configured to return to said emitter information relating to a first technique for acquiring knowledge of the transmit channel. At least one of said receivers is configured to return to said emitter information relating to a second technique for acquiring knowledge of the transmit channel. The method further comprises the selection, from said information received from the receivers, of a subset of receivers, included in the set of receivers, to which the emitter is configured to emit data on said at least one time-frequency resource.

Abstract: A method for communication between an emitter and a receiver, corresponding emitter, receiver and computer program. The development relates to a communication method implemented in a transmission system comprising an emitter and a receiver, the receiver implementing: estimating a covariance matrix of the interference, representative of the spatial structure of the reception interference. According to the development, the receiver further implements: selecting a technique for acquiring knowledge of the emission channel, in a group of techniques comprising a first technique based on a compressed version of the covariance matrix of the interference and at least one second technique, and transmitting to the emitter at least one piece of information relating to the technique for acquiring knowledge of the emission channel selected by the receiver.
