PLANNING MODEL OF TIME-FREQUENCY RESOURCE IN THE DOWNLINK OF LTE TECHNOLOGY
Annotation
Development results of planning mathematical model for time-frequency resource of LTE downlink. The proposed model is aimed to ensure quality of service wireless users by providing user stations with required data rates. A comparative analysis of the proposed model with existing methods in terms of the overall performance of downlink, the degree of balancing capacity and the probability of providing selected user stations with required rate. It is shown that the proposed model under high requirements to the transmission rate of user stations, compared with known methods, makes it possible to increase the degree of balance bandwidth downlink up to 5-20%, and increase the probability of providing user stations with desired transmission rate up to 40–-100%.
