Problems solved by technology

Although this method considers the group size optimization problem, the proposed algorithm is not efficient in finding the optimal solution for group optimization, and cannot effectively find the optimal solution as the number of femto users increases.
In addition, its resource allocation method does not effectively solve the problem of user average interference, nor does it consider the problem of user rate fairness

Abstract

The present invention relates to the technical field of wireless communication, and particularly relates to a femto user resource distribution method based on dense distribution. According to the optimal solution of a function, the grouped femto users are subjected to resource distribution, wherein the solution of the optimal solution of the function comprises a step of substitute a whole user grouping problem into a lingo mathematical platform, a step of determining all feasible solutions of grouping optimization according to a constraint condition, a step of establishing a simplex tableau and obtaining the test number corresponding to each feasible solution according to the obtained feasible solutions, a step of using a direct solution program to process model equality constraint according to the characteristics of the lingo mathematical platform, judging a model type and calling a branch boundary determination program to obtain the optimal solution of the function combined with the simplex tableau. The femto users are grouped according to the strength of the interference between femto groups, the same-layer interference in each group of femto is minimized, the total data rate of a femto cell is maximized, and the solution of the grouping optimization is obtained.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for allocating femto user resources based on dense distribution. Background technique [0002] Compared with the LTE system and the 3G system, the carrier frequency utilization rate of the LTE system has increased, and its path loss has also increased compared with the 3G system. Therefore, the LTE system cannot cover indoors well. Research shows that nearly 90% of data services and 60% of voice services occur indoors, so indoor signal coverage issues need to be resolved in a timely manner. As one of the most promising technologies for indoor wireless communication, femtocell technology has been extensively studied in recent years. Compared with the traditional macro cellular network architecture, the femto base station network architecture can not only expand the coverage, but also improve the system performance. People call a network composed of macro...
