20100287593 | METHOD OF TRANSMITTING DATA FROM AN INFRASTRUCTURE OF A RADIO-COMMUNICATION NETWORK TO USER EQUIPMENT, AND EQUIPMENT FOR IMPLEMENTING THE METHOD - Within a user device to which a radio communication network infrastructure transmits data carried by a sequence of frames broadcast to the user device, each frame comprising a first section comprising data and a second section comprising redundancy information associated with the data of a predetermined number B of previous frames in the sequence, a number of consecutive lost frames is compared to a threshold dependent on the number B of previous frames with which said redundancy information is associated and encoding parameters that generate said redundancy information, and a request to retransmit at least one of the consecutive lost frames is sent to the radio communication network infrastructure if the number of consecutive lost frames exceeds said threshold. | 11-11-2010 |
20110131614 | METHOD FOR TRANSMITTING DATA FROM A RADIOCOMMUNICATION NETWORK INFRASTRUCTURE TO USER EQUIPMENT AND EQUIPMENT FOR CARRYING OUT THE METHOD - Within a radio communication network infrastructure transmitting data organized into a sequence of symbols to a receiving device over a plurality of radio links, data to be transmitted is encoded according to an error correction coding scheme in order to produce a set of systematic symbols and a set of corresponding redundancy symbols; the systematic symbols and a first subset of the corresponding redundancy symbols are transmitted, over a first radio link among said plurality of radio links, in broadcast mode, and a second subset of the corresponding redundancy symbols, distinct from the first one, is transmitted over a second radio link among said plurality of radio links. | 06-02-2011 |
20120008706 | METHOD FOR ENCODING DATA WITH DOUBLE-INTERLACED PARITY SYMBOLS, FOR A RADIO INFRASTRUCTURE, AND ASSOCIATED CODEC - A method is dedicated to encoding data that must be transmitted by means of a wave-based transmission infrastructure, and comprises i) a step consisting of creating in parallel M first matrices having T rows and C columns with subsets of data from B successive received bursts, the subsets of data from each burst being distributed within at least two successive first matrices, ii) a step consisting of creating in parallel M second matrices each having T rows and N columns with parity symbols resulting from encoding the data that is respectively contained in the rows of each of the M first matrices, iii) a step consisting of creating in parallel M first matrices having K rows and C columns with parity symbols resulting from encoding the data that is respectively contained in the columns of each of the M first matrices, and iv) a step consisting of distributing by interlacing, firstly, J subsets of parity symbols from each second matrix into J successive sets, and secondly P subsets of parity symbols from each third matrix into P of these successive sets, and of placing into each of the successive sets the respective data from the successive received bursts. | 01-12-2012 |
20120057641 | TRANSMITTING METHOD AND A RECEIVING METHOD OF A MODULATED DATA STREAM - The present invention relates to a transmitting and a receiving methods of a modulated data stream (MOD). It is characterized in that at the transmitting side, it comprises the steps of: Generating a mixed data stream (MD) on the basis of mixing a first data stream (HP) with a second data stream (LP); Encoding said first data stream (HP) and said mixed data stream (MD); Generating a modulated data stream (MOD) on the basis of mapping said mixed data stream (MD). At the receiving side, it comprises the steps of: Generating a demapped data stream on the basis of demapping said modulated data stream (MOD); Generating a first and a second deinterleaved data streams on the basis of deinterleaving said demapped data stream; Decoding said first deinterleaved data stream; Generating an a priori information on the basis of mixing a part of the first decoded deinterleaved data stream with a mixing vector; and Decoding said second deinterleaved data stream using said a priori information. | 03-08-2012 |
20120275468 | METHOD FOR TRANSMISSION OF LAYERED MULTIMEDIA CONTENTS TO HETEROGENEOUS TERMINALS VIA A TDM/TDMA MULTIPLEXING INFRASTRUCTURE, AND ASSOCIATED PROCESSING DEVICE AND DECODER - A transmission device (ET) is intended to be a component of a time multiplexing (RC) transmission infrastructure with at least one channel and in different transmission time slots, of multimedia contents, such multimedia contents being arranged in at least two complementary data layers. Said device (D) is responsible, in the presence of an association of a time slot to each complementary layer constituting a channel multimedia content, i) for separating the complementary layers of each multimedia content to be transmitted, ii) for chopping up the separated complementary layers into portions of selected sizes, and iii) for incorporating each portion of a layer into a burst so as to transmit each burst during a time slot associated to the layer comprising the portion it integrates. | 11-01-2012 |
