Abstract: A method for optimizing the resources of a data transmission, based on a set of pairs of modulation and first correcting code, includes: determining, for each pair, maximum rate of a second correcting code applied to data transmitted before application of the first correcting code and of modulation wherein the error rate in data received is maximum a target error rate; the second correcting code applied at the medium access layer, to generate packets of redundancy bits based on packets of data bits received supplemented with padding sections, all having the same size; evaluating an item of information representative of the ratio between bits at input of the medium access layer and bits actually transmitted or of transmission bitrate required for solutions associating modulation, first and second correcting codes; selecting, from among solutions associating modulation, first and second correcting codes, to maximize the ratio or to minimize the transmission bitrate.

Abstract: A method for transmitting data packets through a random-access (RA) transmission channel shared by a plurality of user terminals uses and exploits a function F for assigning and distributing transmission resources F(u) to the user terminals, knowledge of the graph of which is shared by the sending user terminals and the receiving station in a preliminary step. During the decoding of the received packets, the graph {(u, F(u)} of the assigning and distributing function is exploited by the receiving station to minimize, or even to decrease to zero, the number of replica-location correlations required in case of failure of the conventional CRD-SA protocol decoding process.

Abstract: A method of controlling congestion in a communications network comprising a plurality of terminals, comprises the steps of: receiving a message or a message fragment at a given instant; evaluating the number of terminals currently sending; defining a congestion window, of duration ΔTf configured so as to be proportional to the number N of terminals currently sending and inversely proportional to the maximum input loading G of the network which makes it possible to obtain a substantially zero rate of retransmissions; for each terminal and each message or message fragment to be sent, make the start of the congestion window coincide with the given instant of receipt of a message or message fragment and define an actual instant of sending of the message or message fragment as a random value taken in the congestion window.

Abstract: A method of adapting the capacity of a contention transmission channel between terminals and a connection station comprises a step of continuous estimation, using measurements in reception of expected bursts, a probability of receiving an empty expected burst Pe, or the probability Pe and a measured probability of receiving a burst Ps, or a probability of receiving a burst having undergone a collision Pc. The method determines a current quantity Gr, monotonically sensitive to the external loading of the contention channel, using an estimated probability, Pe or Pc, or of the two estimated probabilities Pe and Ps, and detects whether a crossing of a threshold from among two predetermined thresholds while deviating from a fixed nominal value of Gr has occurred to decide to increase or decrease the current capacity of the transmission channel. The connection station notifies the terminals in quasi-real-time of the current composition of the transmission channel.

Abstract: A method of space communication for IoT or equivalent services increases the number of terminals served on a space transmission resource while limiting the signaling used by the terminal. This limitation is obtained on the one hand by the allotting to each terminal of a logical beam, corresponding to a predetermined fixed geographical area wherein the terminal lies. This limitation is obtained on the other hand by management, centralized at the level of a central entity for connecting to the space network, of the association of the terminal with a logical beam and of the association of the resources bound for the logical attachment beam. A space telecommunications system implements a method of space communication. The method of space communication allows transparent switchover from a terrestrial system to the space system when the terrestrial system and the space system are integrated to a high degree, particularly at the level of the terminal.

Abstract: A method for transmitting data over an uplink from a terminal TE taken out of a plurality of terminals to a gateway GW switches data packets or packet fragments between a first random access mode and a second demand assigned multiple access DAMA mode. Each terminal TE routes the data packets or the packet fragments over the random access channel RACH or over a demand assigned multiple access channel via a demand assigned multiple access DAMA according to the size of the packets and their class of service, and information items representative of the current transmission resources allocated to the random access channel RACH and to the demand assigned multiple access DAMA mode, the representative information items being notified to the terminals via a return link.

Abstract: A method of processing data in a telecommunications system enabling dynamic adaptation of the quantity of data to transmit. The data is organized into a set of packets contained in a first layer of a communication model. The method includes a first step of passage of an item of information indicating the size of each packet or representative of this size between the first layer and a second layer. It also includes a second step of encapsulation of the packet and of passage of the packet between the first layer and the second layer in a container the size of which is adapted to the information indicating the size of a packet or representative of this size. The method finally includes a third step of application of a block error correcting code to the data contained in the container, the correcting code adapting dynamically to the size of the container.
