  • Patent number: 9253790
    Abstract: Radio blocs (BRjp) shared in a predetermined frequency band during a periodic radio frame (TRi) between base stations (BS) are allocated to applications in base stations and mobile stations. Each radio block spreading on frequencies (Cj) of said band during a time slot (M?t) of the radio frame and can be associated with an uplink or a downlink. To meet quality-of-service parameters required by an application, a base station estimates occupation rates of the radio blocks during consecutive radio frames, and allocates to the application at least one radio block having an occupation rate less than a threshold and a periodicity expressed in period of frame and depending on the required quality-of-service parameters. The base station are autonomous for the radio block allocations.

  • Patent number: 9130715
    Abstract: In order to acquire first subbands in at least a central band of a broad frequency band, in which subbands frames are transmitted by a base station (BSBB) of a broadband network (RBB) which is co-located with a network (RNB) having narrow subbands comprised in the broadband, a mobile (MBBB) which does not know the distribution of the subbands correlates subsequences of a generated reference signal with subsequences which are respectively detected in the subbands and compares correlation coefficients against a threshold. By knowing the distribution of the first subbands, the mobile is able to process the signaling transmitted by the base station, in order to access allocated resources, after a synchronization phase.

  • Publication number: 20150173061
    Abstract: A transmission of information is established between an emitting mobile terminal and at least one receiving mobile terminal of the same group of terminals pertaining to a shared-resource radiocommunication network operating in a direct mode includes the step of emitting by the emitting terminal of a transmission request to inform the other receiving terminals of the group of its intention to transmit information. Each receiving terminal of the group then determines whether, on the basis of at least one pre-defined selection strategy, it will accept the transmission of information. If it will, the receiving terminal transmits a return signal comprising data relating to said emitting terminal to the other terminals of the group. Then, the emitting terminal checks whether it respects the transmission conditions. If it does, the emitting terminal transmits the information to the other terminals in its group via at least one resource allocated to the group.

  • Publication number: 20150111590
    Abstract: A telecommunications network, especially an LTE type network, is adapted to a change in configuration. The telecommunications network includes at least a first transmission device, of base station or transmission relay type, and a second transmission device, of base station or transmission relay type. There is no radio link in existence between the first transmission device and the second transmission device before the change in configuration. The process for change includes: detecting a change in the configuration of the telecommunications network; allocating radio resources in the communications frames of the first communications element for determination of the transmission quality with the second communications element; and establishing a radio link between the first transmission device and the second transmission device if the determined transmission quality is advantageous. The process is implemented by a telecommunications networking infrastructure and by a transmission device.

  • Publication number: 20140348042
    Abstract: The object of the present invention is a method for selecting a terminal of an HD-FDD duplexing model. The invention enables the complexity of a switch of a terminal operating in an HD-FDD duplexing mode, at a level equivalent to that of a terminal operating in a TDD or FDD duplexing mode, to be reduced. To do this, thanks to the invention, it is provided that the terminal operating in an HD-FDD duplexing mode receives notifications or information via a network that programs the HD-FDD terminals through different uplink and downlink transmission models illustrated in FIG. 1. It may also be provided that the terminal operating in an HD-FDD duplexing mode has knowledge of the HD-FDD model to use for its communication. In this event, the complexity of its communication is reduced to the same level as that of a terminal operating in TDD mode.

  • Publication number: 20140004845
    Abstract: A first broadband network divided into sectors and a second narrowband network have collocated cells and a common wide frequency band. The interference produced by the first network on the second network is reduced for a carrier to interference ratio threshold allowable at the reception in the second network. For example, a base station (BSBB,nc) in a given cell (CBB,nc) of the first network attenuates by an attenuation parameter the emission power of each subcarrier which is adjacent to a carrier of one of the groups allocated to preselected cells (CNB,i) of the second network in a sector (Sns) of the given cell and on levels (L0 to LI-1) starting from the given cell (CBB,nc). The attenuation parameter is low for a level close to the given cell.
