    摘要： The invention relates to a method for establishing a quality indicator (CQI) of a radio transmission channel in a first cell of a cellular network using a plurality of orthogonal frequency-division multiplexed subcarriers for transmitting data, said method including: a first transmitter device (NB
    1 ) located in the first cell transmitting (11) a reference control signal (SP
    1 ) including a total-load control signal (SP
    CT ) modulating one or more of said orthogonal subcarriers, during one or more first symbol times dedicated to the transmission of symbols other than data symbols, and a useful-load control signal (SP
    CE ) modulating one or more orthogonal subcarriers during at least one second symbol time dedicated to the transmission of data symbols; for every cell adjacent to the first cell in the cellular network, a transmitting device (NB
    2 ) located in said adjacent cell transmitting (13) an interfering control signal (SP
    2 ) modulating, during the first symbol time(s) during which the total-load control signal (SP
    CT ) modulates one or more subcarriers, said subcarrier modulated by the total-load control signal (SP
    CT ); a receiving device (M) located in the first cell measuring (20) a quality indicator of the channel under the total load (CQI
    CT ) using the total-load control signal (SP
    CT ) and a quality indicator of the channel under the useful load (CQI
    CE ) using the useful-load control signal (SP
    CE ); and determining (30) the quality indicator (CQI) of the radio transmission channel according to the quality indicator of the channel under the useful load (CQI
    CE ) and the quality indicator of the channel under the total load (CQI
    CT ).
