摘要： The present invention relates to a scheduling method in a multi-user communication system. Said method categorises packets from different users as urgent packets and non-urgent packets, assigns to urgent packets the transmission resources for obtaining the best link qualities by giving preference to the most urgent packets, assigns to non-urgent packets the remaining resources, and transmits each non-urgent packet with a transmission power lower than that which would be necessary for transmitting it with a maximum spectral efficiency, in view of the quality of service required on the link.

摘要： The present invention relates to an asynchronous communication method in a wireless sensor network comprising a tree structure. For each node of the network, the communication is organized as a sequence of time frames, each frame including a listening phase possibly followed by a receiving phase and/or a transmitting phase. The method, of the preamble sampling type, enables a node to make a time appointment to its child node to transmit them a time window allocation message, each child node then transmitting at least one data packet in the window it has been allocated to. By minimizing the collision risk between packets and by maximizing the time during which the sensors go to sleep, the communication method both reduces the latency and the consumption within the network.

摘要： The present invention relates to a centralized power allocation method in a wireless telecommunication system comprising at least a first couple of terminals, consisting of a first transmitting terminal and a first receiving terminal, and a second couple of terminals, consisting of a second transmitting terminal and a second receiving terminal. A control node partitions the interference diagram between the communication of the first couple and the communication of the second couple, into different areas, each area being associated to a type of processing of the interference. The control node calculates the minimum power curve for each communication in each said area. The power values to be allocated are given by the coordinates of the point of intersection of both curves in said diagram.
