摘要： A wireless OFDMA telecommunications system comprising a transmitter adapted to transmit, by means of an OFDM modulator, a plurality of data packets destined for receivers of a plurality of users, via the same plurality of transmission channels, the transmission channel of a user being associated with a group of sub-carriers of the OFDM multiplex and a set of OFDM symbol times of a transmission interval, each receiver being adapted to signal to the transmitter the loss of a packet transmitted over the transmission channel of the corresponding user, said transmitter further comprising a packet scheduler adapted to control retransmission of each packet lost by means of said modulator. Each receiver comprises detection means of an outage situation of the transmission channel of the corresponding user and signals this to said transmitter by means of an outage information (OUTAGE/NOUTAGE). In the event of outage, said scheduler prohibits any retransmission of a packet lost over said channel during a predetermined time (Tout) greater than or equal to the coherence time of said channel.

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.
摘要翻译：本发明涉及一种包括树形结构的无线传感器网络中的异步通信方法。对于网络的每个节点，通信被组织为一系列时间帧，每个帧包括可能跟随接收阶段和/或发送阶段的收听阶段。前导采样类型的方法使得节点能够对其子节点进行时间约定以向它们发送时间窗口分配消息，然后每个子节点在其已被分配的窗口中发送至少一个数据分组。通过最小化数据包之间的冲突风险，并通过最大限度地延长传感器进入睡眠状态的时间，通信方法既能减少网络内的延迟和消耗。

摘要： The present invention relates a voice communication method between a plurality of users sharing the same transmission band. The resource is accessed by time division under the supervision of a control node. During a polling step, any user wishing to speak transmits (210) a request to the control node. The control node allocates (220) transmission frames to the requesting users or merely to some of these users. Users allocated a transmission frame can then transmit (230) a voice packet to the respectively allocated frames thereof. The transmission frames are interleaved temporally so as to give the impression of full-duplex communication during voice reproduction.
摘要翻译：本发明涉及共享相同传输频带的多个用户之间的语音通信方法。资源在控制节点的监督下通过时分进行访问。在轮询步骤期间，任何希望发言的用户向控制节点发送（210）请求。控制节点将（220）个传输帧分配给请求用户，或仅向这些用户中的一些用户分配。然后，分配了传输帧的用户可以将语音分组发送（230）到其分配的帧。传输帧在时间上交错，以便在语音再现期间给出全双工通信的印象。
