On Uplink Interference Scenarios in Two-Tier Macro and Femto Co-Existing UMTS Networks

Shi, Zhenning; Reed, Mark; Zhao, Ming

Description

A two-tier UMTS network is considered where a large number of randomly deployed Wideband Code Division Multiple Access (WCDMA) femtocells are laid under macrocells where the spectrum is shared. The cochannel interference between the cells may be a potential limiting factor for the system. We study the uplink of this hybrid network and identify the critical scenarios that give rise to substantial interference. The mechanism for generating the interference is analyzed and guidelines for...[Show more]
