Communication method in a network (1), of data being transmitted from a wireless master station (10) to a recipient station (14) via one of the wireless slave stations (10 to 12). In order to guarantee a quality of service, the method comprises a first election of a first slave station, then a first transmission of at least one data packet present in the first queue, the first transmission being carried out from the master station to the first slave station, a second election of a second slave station, then a second transmission of at least one data packet present in the second queue, the second transmission being carried out from the master station to a second slave station and the first transmission continuing as long as the first queue is not empty.

The invention relates to a bus, which is connectable to a primary master and to secondary masters, the bus being suitable for the transmission of data between the peripherals. In order to ensure a minimum rate and/or maximum latency between the secondary masters, when the primary master uses a small time fraction available on the bus, said primary master is provided with the highest priority and comprises means for wirelessly accessing to a medium. The inventive method for accessing to the bus consists in authorising the primary master to access to the bus upon the request thereof and in selecting the access to the bus for the secondary masters when the primary master peripheral does not request said access to the bus.

The invention relates to a method of communication adapted to the transmission of data packets that can be transmitted according to various physical modes.In order to optimize transmission, the method comprises the following steps: reception of packets, each packet being sent in at least one radio burst associated with a physical mode chosen from a set of at least two physical modes; estimation of the packet error rate for each physical mode of the set.

The invention concerns a method for the rate regulation of radio link probing in a communication network comprising at least a receiver terminal and at least one transmitter terminal, characterized by the steps, at the level of the receiver terminal, of: determining the amount of data sent by each transmitter terminal to the receiver terminal through respective radio links, when a probing of a link is to be made, probing the link corresponding to the transmitter terminal having sent the greatest amount of data.

The present invention concerns a method and a device for transmitting data between a sender, and at least two receivers, in a network where a data between a sender and a receiver is carried on a connection and where a unicast connection enables a sender to send the data and a receiver to acknowledge a reception of the data. The method comprises the steps of opening a unique unicast connection identified with a connection identifier; and indicating the connection identifier to the sender and the receivers, so that the sender sends the data on the unicast connection, and the receivers receive the data on the unicast connection.

In order to prevent breaks in a communication network comprising at least one subscriber station and at least two base stations synchronised and connected to each other by a communication link, a method is provided comprising a time resource allocation step for the transmission and/or reception of packets by the at least one subscriber station, the time resource being specific to each subscriber station and being able to be used with all the base stations.

The present invention concerns a data transfer system for transferring data signals between a system input and a system output, and associated products.The system comprises a first data consuming set, receiving the data signals (SGNL1) from the system input, writing them therein and reading them for sending them towards a second data consuming set, the second set receiving the data signals (SGNL0), writing them therein and reading them for sending them (SGNL2) to the system output, and transfer means transferring the data signals from the first to the second data consuming set.The first set incorporates within the data signals to be transmitted, read requests (rd_req1) for reading the data signals from the first data consuming set. The transfer means carry those read requests with the data signals, and the second set receives them for synchronization between the first and second sets.
