| 20080214119 | Link adaptation telecommunication system - The invention relates to a wireless telecommunication system including a transmitter and a receiver, said transmitter being used to transmit data packets to the receiver, said receiver including error detection means ( | 09-04-2008 |
| 20090013235 | Conditional decoding receiver - This invention relates to a wireless telecommunication system receiver, comprising a demodulator ( | 01-08-2009 |
| 20090163138 | HYBRID TERRESTRIAL-SATELLITE TELECOMMUNICATIONS NETWORK WITH ADAPTABLE TERRESTRIAL RELAY-STATIONS - The general field of the invention is that of hybrid telecommunication networks comprising at least one telecommunication relay-satellite emitting at least one signal covering a given geographical zone organized into sub-zones of smaller dimension, a terrestrial relay-station able to receive, to process the satellite signal and to emit a signal in at least one of the sub-zones and mobile reception terminals. The network according to the invention comprises first means making it possible to carry out a mapping of the quality of reception of the satellite signal in each sub-zone; second means making it possible to transmit the mapping information to the terrestrial relay-station. The relay-station comprises third means making it possible, as a function of the reception mapping information, to emit a signal dependent on the said mapping making it possible to improve the quality of reception in its reception sub-zone. | 06-25-2009 |
| 20100061321 | METHOD OF SCHEDULING PACKETS - The invention relates to a method of scheduling packets in a multi-access telecommunication system sharing a plurality of transmission resources. The packets relating to the various accesses are classed ( | 03-11-2010 |
| 20100115373 | DISTRIBUTED TURBOCODER FOR BLOCK-FADING CHANNELS - A cooperative communications system comprising a source terminal, at least one relay terminal and a destination terminal. The system also comprises a distributed turbocoder over the source terminal and at least the relay terminal. The first part of the turbocoder residing on the source terminal and/or the second part of the turbocoder residing on the relay terminal is(are) equipped with a frequency scheduler (FS | 05-06-2010 |
| 20110013584 | METHOD TO ALLOCATE TRANSMISSION RESOURCES IN A CELL NETWORK OF COOPERATIVE TYPE - The invention concerns a method to allocate transmission resources in a cell network of cooperative type. Each cell comprises a source, a receiver and optionally a half-duplex relay to relay data transmitted by the source to the receiver. The invention draws advantage from the half-duplex mode of a relay belonging to a cell, by allocating to the source of a neighbouring cell a resource used by this relay during one same transmission timeslot. | 01-20-2011 |
| 20110044314 | MULTI-ACCESS TELECOMMUNICATIONS SYSTEM WITH ADAPTED STRATEGY FOR PACKET RETRANSMISSION - A wireless OFDMA telecommunications system comprising a transmitter adapted to transmit, by means of an OFDM modulator, a plurality of data packets destined for receivers of a plurality of users, via the same plurality of transmission channels, the transmission channel of a user being associated with a group of sub-carriers of the OFDM multiplex and a set of OFDM symbol times of a transmission interval, each receiver being adapted to signal to the transmitter the loss of a packet transmitted over the transmission channel of the corresponding user, said transmitter further comprising a packet scheduler adapted to control retransmission of each packet lost by means of said modulator. Each receiver comprises detection means of an outage situation of the transmission channel of the corresponding user and signals this to said transmitter by means of an outage information (OUTAGE/NOUTAGE). In the event of outage, said scheduler prohibits any retransmission of a packet lost over said channel during a predetermined time (T | 02-24-2011 |
| 20110136527 | METHOD FOR CONTROLLING POWER IN A CELLULAR NETWORK WITH A SURPLUS OF TRANSMISSION RESOURCES - A method for controlling the transmission power of a terminal in a cellular telecommunications network, in which the number of transmission resources is greater than the number of users is disclosed. In one aspect, the number of additional transmission resources necessary for the communication of the user if a modulation and coding scheme with minimal spectral efficiency is used, and whether these resources are available, are determined, they are allocated to the user, and the transmission power of the terminal is set to the transmission power enabling the required quality of service to be obtained by using the predetermined modulation and coding scheme. | 06-09-2011 |
