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.

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.

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.
