Abstract: A transmission method for an OMAMRC telecommunication system with M sources (S1, . . . , SM), optionally L relays and a destination, M≥2, L≥0. In such a solution, when a source was unable to be decoded by the destination, the latter organises a simultaneous retransmission, by the set of nodes in the system that decoded the source, of a message transmitted by the latter.

Abstract: A method for transmitting signalling information from a base station to at least two terminals associated with the base station. The method includes transmitting at least two physical unicast control channels each intended for one of the at least two terminals, each physical unicast control channel carrying a unicast control message carrying transmission parameters intended to be used for the transmission of a multicast control message, and each physical unicast control channel being encoded with a temporary network identifier uniquely identifying the terminal for which it is intended, the multicast control message carrying at least two sets of transmission parameters for use in transmitting pay load data to the at least two terminals respectively.

Abstract: A method for processing radio-frequency signals received on R antennas, where R≥2, includes, implemented by a radio unit: obtaining a frequency representation of the radio-frequency signal received on an antenna, demapping the frequency representations, first estimation of the transmission channel of the radio-frequency signals and of a noise-plus-interference covariance, projecting a vector of R complex samples onto a vector of L complex samples, referred to as projected samples, transmitting the vector of L projected samples to a base band processing unit, as well as the following, implemented by the base band processing unit: receiving the vector of L projected samples transmitted by the radio unit, demapping the L projected samples, second estimation of the transmission channel of the radio-frequency signals, after projection, equalising the L projected samples, taking account of the second channel estimation, processing the equalised symbols.

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 of processing radio-frequency signals received on R antennas, and corresponding reception method, decoding method, computer program and system. The method for processing radio-frequency signals received on R antennas, where R≥2, includes, implemented by a radio unit: obtaining a frequency representation of the radio-frequency signal received on an antenna, demapping the frequency representations, estimating the transmission channel of the radio-frequency signals and a noise-plus-interference covariance, projecting a vector of R associated complex samples onto a vector of L complex samples, referred to as projected samples, transmitting at least one item of control information and the vector of L projected samples to a base band processing unit, and the following, implemented by the base band processing unit: receiving the item of control information transmitted by the radio unit, receiving the vector of L projected samples transmitted by the radio unit, equalising the L projected samples, processing the equalised symbols.
