摘要

热点微基站作为异构部署的重要组成部分，具有部署灵活、可规划性高、室外覆盖能力强等特点。由于宏、微基站并存，干扰环境复杂，给系统的无线资源管理带来了新挑战。本文以热点覆盖的小区选择为研究内容，在小区范围扩展技术的基础上，结合每个热点微基站所处的干扰环境，设计了差异化的接入偏移量，并对其可行性进行了讨论，有效地提高了小区边缘与平均谱效率。

Abstract

As an important part of the heterogeneous deployments

picocells are flexible to be deployed

easy to be planned and better for outdoor coverage.Due to the coexistence of macro and micro base stations

interference environment is complex

but also brought new challenges to the system radio resource management.This paper studies the cell selection for picocell networks.Based on cell range extension

a specific bias for each picocell is designed

according to its interference environment

which can effectively improve the cell average and cell edge spectrum efficiency

compared with those of fixed bias value.
