Abstract
In order to meet the growing demand for mobile broadband and users’ expectations, it is necessary improve data performance overall and at cell edges. The success of LTE heterogeneous networks (Het- Nets) with macrocells and picocells critically is contingent on efficient spectrum division between high-power macros and low-power picos. Two important tasks in this situation are: 1) Determining the amount of radio resources that macrocells should offer to picocells, and 2) Influential the association rules that resolve which user equipments (UEs) should associate with picos. In this system, progress a novel algorithm to solve these two joined problems in a dual manner. Proposed algorithm has provable guarantee, and furthermore, it explanations for network traffic load, topology, and macro-pico interference map. Our result is standard compliant and can be executed using the notion of Almost Blank Subframes (ABS) and Cell Selection Bias (CSB) proposed by LTE standards. Simulation result also show general evaluations using RF plan from a real network and discuss self-optimized networking (SON)-based improved inter-cell interference coordination (eICIC) employment.
