This invention proposes a method for assigning resources in the downlink based on the CQI parameter reported by the UE compatible with the LTE standard. The method looks for saving signalling resources when conditions are such that no major advantage can be obtained from frequency selective scheduling. The method is divided into two processes, a non real time process used to determine whether the conditions for its application are present; and the new assignment procedure. For the latter, the method defines different assignment procedures based on whether the CQI value reported by the UE is higher or not of a given threshold whose calculation is also defined. A new parameter, the MAB, is defined for the assignment in case of CQI higher than the threshold, while frequency distributed scheduling is used if it is lower. The proposed method is believed to improve the LTE spectral efficiency with reduced complexity.
