摘要:
The invention relates to an emission method for a wireless network comprising a plurality of stations emitting at the same frequency. In order to optimize the use of radio channels, the method comprises the following steps implemented by at least one relay station RS of the plurality of stations: reception via a first wireless channel of a first signal (512) representative of data (503), and emission via a second wireless channel of a second signal (514) representative of the same received data (503) to an assembly comprising at least one receiver, the second signal being emitted synchronously with a third signal (504) representative of the same data (503) and intended to be emitted by at least one base station BS1 of the plurality of stations. The invention also relates to the corresponding reception method.

The invention relates to a method for transmission in a wireless network comprising a plurality of base stations and at least one mobile terminal, a mobile terminal (MT) transmitting a same signal (704) intended for the plurality of base stations (BS1, BS2, BS3). In order to optimise the synchronisation of the mobile terminal with the plurality of base stations, the method comprises a step of transmission of an item of information representative of a first temporal offset intended for the mobile terminal, the first offset being according to at least one reception time (740, 750, 760) of the first signal by at least one base station (BS1, BS2, BS3).The invention also relates to the corresponding method for reception.

The invention relates to a method for transmission of data in a wireless network comprising a plurality of base stations broadcasting data at a same frequency and a plurality of mobile terminals. In order to overcome inter-cell transfer at the level of mobile terminals, the method comprises: assignments of first and second sub-sets of base stations at respectively at least a first and at least a second mobile terminal, the assignments varying in time according to first and second parameters, the two sub-sets having at least one base station in common and each at least having a specific base station, synchronized transmissions of respectively the base stations of the first and second sub-set of first and second specific data modulated with first and second modulations to respectively the at least first and second mobile terminals. The invention also relates to the corresponding method for reception of data.

The invention relates to a method for transmitting in a wireless network comprising a plurality of base stations, that transmit frames at a same frequency, and at least one mobile terminal. In order to optimise the size of a frame header, the method comprises: transmission, by a first set comprising at least two base stations, of at least a first part of the frame header on a same first physical channel comprising at least a first temporal interval, transmission, by at least a second set comprising at least one base station, of at least one second part of the frame header on a second physical channel comprising at least one second temporal interval different to the first temporal interval, the at least one second set being different from, but included in, the first set. The invention also relates to the corresponding method for reception.
摘要:
The invention provides a method of evaluating a path in a data-receiving system using multi-carrier modulation. A confidence indicator is determined for each data item received so as to provide a stream of confidence indicators parallel to the datastream received. The confidence indicators are ordered identical to the data received. The invention provides a device comprising means for evaluating a confidence indicator for each carrier and means for laying out a stream of confidence indicators identical to a datastream received.
