  • Patent number: 9439132
    Abstract: The invention relates to a method for the conditional transmission of a cellular frame by a cellular device (10) over a cellular network (11) comprising cells (111). The invention is characterised in that it comprises steps in which: the device (10) scans (S2) the network (11) in order to detect cells (111); if at least one cell (111) is detected, the device (10) determines (S202) if at least one of the cells detected belongs to a list stored in a database (BDD) of the device (10) and listing the cells in which the transmission of a cellular frame is prohibited; and if none of the cells detected belongs to the list, the device (10) determines (S203) the value of a mobility variable (M) indicating whether or not the device is authorised to transmit, and the device (10) transmits (S204) a cellular frame when the mobility variable (M) indicates that the device is authorised to transmit. The invention also relates to a device for implementing said method.

  • Publication number: 20070293147
    Abstract: A method and apparatus is disclosed for performing a multi-equalization of a transmitted signal on a channel having varying characteristics comprising equalizing the transmitted signal using a plurality of setting defining a plurality of equalizing functions to provide a corresponding plurality of symbol signal, synchronizing each of the plurality of symbol signals to provide a plurality of synchronized signals, selecting at least one of the plurality of synchronized signals according to at least one transmission performance criterion and providing the selected one of the plurality of synchronized signals.
