First Claim
Patent Images
1. A method for data transmission in a radiocommunication network, comprising:
- receiving terminal data carried by a first radio signal from a communication terminal at a communication satellite directly from the communication terminal and from the communication terminal via one or more first relay terminal, wherein the first radio signals are directed toward a communication station;
combining the first radio signal received directly from the communication terminal and the first radio signal received from the one or more first relay terminal to produce a combined terminal signal at the communication satellite that has increased energy in relation to the individual radio signals received by the communication satellite; and
transmitting the combined terminal signal from the communication satellite to the communication station.

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).
