Abstract
A radiocommunication network includes at least one communication station (GW) adapted to exchange data by radio with radiocommunication terminals (T1-T5). This network is adapted to use a data transmission method wherein, each time a source radiocommunication terminal (T1) wishes to transmit data to its communication station (GW), the identifier of at least one active neighbor relay communication terminal (T2, T3) is determined in the source terminal (T1) in order to transmit signals representing the data to be transmitted by radio to each relay terminal so determined so that it relays them to the communication station (GW).
