Abstract: A system for transmitting data over a physical resource including a layer configured to manage the physical resource and to guarantee a quality of service, and a first sub-layer configured to supply a transmission support in accordance with the quality of service and to segment the data into transmission units. The first sub-layer reduces a size of at least one of the transmission units when transmission conditions on the physical resource are degraded. A second sub-layer is configured to transmit at least one of the transmission units over the physical resource during each of transmission time intervals. The transmission time interval is a periodic time interval during which the second sub-layer is allowed to access the physical resource. A physical layer is configured to perform error correction coding or decoding of the data.

Abstract: The present invention relates to a method for transmitting information in a telecommunication system comprising multiple local networks, which information is to be transmitted within at least one frame FRk (fot k=1 to K). The method according to the invention includes a section creation step for generating at least one section to be included in a given frame, e.g. FR1, which section includes multiple slots, e.g. SLT32, each slot being allocated to a given terminal for enabling said terminal to transmit information. The invention enables a terminal to identify itself simply by transmitting said information within the slot allocated to said terminal.

Abstract: The present invention concerns a method for terminals to have access to a common resource of a network. It is characterised in that the said network defines the access conditions of a plurality of access classes and transmits the said conditions to all the terminals liable to have access to the said resource and in that a terminal wishing to have access to the said resource determines the access class to which it belongs according to its access state and gains access to the said resource according to the access conditions of the said access class thus determined.

Abstract: The invention concerns a method for channel allocation in an ad-hoc radio communication system comprising devices gathered in several piconets. A piconet coordinator (PNC) is defined for each piconet. A Code Division Multiple Access (CDMA) scheme is implemented. The set of available codes is split into pre-defined disjoined subsets of codes (CI) known by each device.
