Abstract: 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.

Abstract translation: 本发明提出了一种基于与LTE标准兼容的UE所报告的CQI参数来分配下行链路资源的方法。 当条件使得从频率选择性调度不能获得主要优点时，该方法寻求保存信令资源。 该方法分为两个过程，一个用于确定其应用条件是否存在的非实时过程; 和新的分配过程。 对于后者，该方法基于UE报告的CQI值是否高于也定义其计算的给定阈值来定义不同的分配过程。 在CQI高于阈值的情况下，为分配定义新参数MAB，而如果低参数则使用频率分布式调度。 所提出的方法被认为是以降低的复杂性来提高LTE频谱效率。
