The invention concerns multi-carrier based digital telecommunication systems where the channel is used to transport several data streams according to the frequency division multiple access scheme. The proposed method concerns a mapping of data on physical resource in a transmission system where data of elementary streams is distributed over several physical resource blocks, and within each resource block in order to get data from a plurality of elementary streams on at least one sub-carrier and at least a symbol time of each physical resource block. This allows to achieve a good diversity of the allocation of the different streams, leading to the advantage, among others, that poor transmission conditions affecting a particular sub-carrier or a particular time duration, will not concentrate its effects on a particular stream.
Method of data transmission in a multi-carrier based transmission system, the transmission being made over a channel shared among a number of data streams according to a frequency division multiple access scheme, data from different sources or to different destinations being sent by streams of symbols, the physical resource blocks being defined as blocks constituted by a given number of consecutive sub-carriers and a transmission time of a given number of symbol durations, some of these streams beind transmited in a distributed mode, comprising the following steps:
