20080280594 | Method for Transferring the Context of a Mobile Terminal in a Wireless Telecommunication Network - The present invention concerns a method for obtaining a context of a mobile terminal ( | 11-13-2008 |

20100150259 | METHOD AND A DEVICE FOR DETERMINING SHIFTING PARAMETERS TO BE USED BY AT LEAST A FIRST AND A SECOND TELECOMMUNICATION DEVICES - The present invention concerns a method for determining shifting parameters p | 06-17-2010 |

20100195619 | METHOD AND A DEVICE FOR ADJUSTING THE TRANSMISSION POWER OF SIGNALS - The present invention concerns a method for transferring information enabling the adjustment of the transmission power of the signals transferred and/or received by a first base station through a wireless interface, a cell of the first base station being at least partly comprised in a cell of a second base station. A mobile terminal for which a handover has been or has to be conducted between the first and second base stations obtains information related to the path between the second base station and the mobile terminal and transfers information to the first base station. | 08-05-2010 |

20100220802 | METHOD FOR TRANSMITTING OPTIMALLY DIVERSIFIED INFORMATION IN A MIMO TELECOMMUNICATION SYSTEM - A method for transmitting data in a telecommunication system including at least one transmitter comprising at least two transmitting antennas and at least one receiver comprising at least one receiving antenna, the method including: transforming a plurality of bits of the data to be transmitted into a plurality of symbols by modulating the plurality of bits of the data at the transmitter; generating a first vector formed by the plurality of symbols at the transmitter; preparing a modified matrix by modifying an original matrix based on the number of rows of the first vector, the original matrix being predefined at the transmitter; generating a second vector by multiplying the first vector with the modified matrix at the transmitter; and transmitting symbols forming the second vector over communication channels established between the at least two transmitting antennas of the transmitter and the at least one receiving antenna of the receiver. | 09-02-2010 |

20110306334 | METHOD AND A DEVICE FOR IDENTIFYING AT LEAST ONE TERMINAL FOR WHICH SIGNALS TRANSFERRED BETWEEN THE AT LEAST ONE TERMINAL AND A BASE STATION HAVE TO BE RELAYED BY A RELAY - A method for identifying at least one terminal for which signals transferred between the at least one terminal and a base station of a wireless cellular telecommunication network have to be relayed by a relay, the base station providing a random access channel enabling any terminal to notify to the base station the presence of the terminal by transferring a random access signal to the base station. The relay: transfers the random access signal to the base station for obtaining a list of at least one terminal, receives the list, identifies, from the received list, at least one terminal for which signals transferred between the at least one identified terminal and the base station have to be relayed by the relay, and relays signals between the at least one identified terminal and the base station. | 12-15-2011 |

20120002629 | METHOD AND A DEVICE FOR DETERMINING A SHIFTING PARAMETER TO BE USED BY A TELECOMMUNICATION DEVICE FOR TRANSFERRING SYMBOLS - A method for determining a shifting parameter P to be used by a telecommunication device for mapping symbols on sub-carriers, the telecommunication device including at least two transmit antennas, the symbols being transferred through each antenna of the telecommunication device on at least an even number K, strictly greater than two, of sub-carriers allocated to the telecommunication device. The telecommunication device transfers on a first antenna on each sub-carrier âkâ, a signal representing a symbol âX | 01-05-2012 |

20140334332 | METHOD FOR OBTAINING INFORMATION REPRESENTATIVE OF THE CHANNEL QUALITY INDICATION ON AT LEAST ONE FREQUENCY SUBBAND - The present invention concerns a method and a device for obtaining, by a first telecommunication device and from a second telecommunication device, information representative of the channel quality indication on at least one frequency subband, the first and the second telecommunication devices being linked through a wireless telecommunication network using a plurality of frequency subbands. The frequency subbands are grouped into groups of at least one frequency subband, and the first telecommunication device transfers a message to the second telecommunication device, the message comprising information identifying a first group of at least one frequency subband, receives, from the second telecommunication device, for each frequency subband comprised in the first group, an information representative of the channel quality indication determined by the second telecommunication device for the frequency subband comprised in the first group. | 11-13-2014 |

20140334428 | METHOD FOR OBTAINING INFORMATION REPRESENTATIVE OF THE CHANNEL QUALITY INDICATION ON AT LEAST ONE FREQUENCY SUBBAND - The present invention concerns a method and a device for obtaining, by a first telecommunication device and from a second telecommunication device, information representative of the channel quality indication on at least one frequency subband, the first and the second telecommunication devices being linked through a wireless telecommunication network using a plurality of frequency subbands. The frequency subbands are grouped into groups of at least one frequency subband, and the first telecommunication device transfers a message to the second telecommunication device, the message comprising information identifying a first group of at least one frequency subband, receives, from the second telecommunication device, for each frequency subband comprised in the first group, an information representative of the channel quality indication determined by the second telecommunication device for the frequency subband comprised in the first group. | 11-13-2014 |

20150049845 | METHOD AND A DEVICE FOR DECODING DIFFERENTIALLY MODULATED SYMBOLS - A method for decoding differentially modulated received symbols, the differentially modulated received symbols corresponding to a transmission of a differentially modulated version of a codeword out of a set of possible codewords, the received symbols being transferred onto resources of a channel, the resources being equally spaced. A receiver, for each possible codeword: obtains a vector of differentially demodulated symbols by differentially demodulating the differentially modulated received symbols obtained by combining two consecutive differentially modulated received symbols; calculates the product of each differentially demodulated symbol by the conjugate of the element of the codeword having the same rank within the codeword as the differentially demodulated received symbol; calculates the sum of the products; decodes the vector of differentially demodulated symbols by selecting the codeword for which the sum of the products is the maximum. | 02-19-2015 |

20150063477 | METHOD AND A DEVICE FOR INCREASING THE AMOUNT OF INFORMATION BITS COMPRISED IN A SYMBOL - A method for increasing the amount of information bits comprised in a symbol transferred by a source to at least one receiver. The symbol is representative of a modulated base sequence obtained by encoding a sequence of base bits selected by the source and by modulating the encoded selected sequence. The modulated base sequence has fixed points. The source encodes the selected sequence of base bits and a sequence of supplementary bits, obtains a modulated base sequence by modulating the encoded selected sequence of base bits, obtains a modulated altering sequence by modulating the sequence of supplementary bits, alters the modulated base sequence by modifying at least a part of the values of its fixed points using the modulated altering sequence in order to obtain a modulated altered sequence, and transfers the modulated altered sequence under the form of an altered symbol. | 03-05-2015 |
