    摘要: The method for estimating a propagation round trip delay, existing between a base station and a terminal, and comprised within a predetermined round trip delay range, comprises the following steps:
    transmitting from the base station on a downlink a start order signal (30) to the terminal,
    after reception by the terminal of the end of the start order signal, sending a signature signal from the terminal to the base station on a uplink,
    receiving at the base station within a signature receiving time slot (28) the signature signal (34, 38, 42),
    processing at the base station the received signature signal to provide a round trip delay information.
    The processing step comprises a cyclic correlation step performed within a fixed correlation time window (54) by using a unique reference sequence (48).

    摘要: 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 or 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.
