METHOD AND APPARATUS FOR DETERMINING USER THROUGHPUT OF CELL IN LTE SYSTEM

摘要

Disclosed in the present invention are a method and apparatus for determining user throughput of a cell in a Long-time Evolved (LTE) system, wherein the method comprises the steps of: obtaining the mapping relationship between Signal-Noise-Ratio(SNR) and throughput of the cell via link simulation; computing average Resource Block(RB) number distributed for each user in the cell according to the bandwidth and frequency multiplexing mode of the LTE system; obtaining Carrier to Interference plus Noise Ratio(CINR) for each user in the cell via network simulation; determining the user throughput of the cell according to the mapping relationship between SNR and throughput of the LTE system, the RB number, and the CINR. By obtaining the mapping relationship between SNR and throughput of the LTE system, the average RB number and the CINR for the user, and determining the throughput of the cell with the obtained parameters, the present invention thus solves the problem related to estimating user throughput distribution of the LTE system in related technologies, thereby achieving the effect of estimating user throughput distribution of the LTE system quickly and correctly.
