Keywords: | 3GPP LTE LTE Advanced CoMP femtocell downlink throughput |
Abstract (eng): | 3GPP includes the LTE air interface specifications in various releases. Several interesting features such as Home Enhanced Node-B (HeNB) known as femtocells and Coordinated Multipoint Transmission (CoMP) have been introduced. According to the requirements, Long Term Evolution is expected to provide higher data rates especially at cell edge. In this thesis, a noteworthy implementation of Coordinated Multipoint Transmission is proposed to fulfill the performance targets of 4G cellular networks. The coordination takes place in a femtocell network for downlink in this study. The coordination enhances the signal quality received at the user terminal resulting in an improvement in the indoor coverage, cell capacity, lower CAPEX and enhanced network topology. This thesis studies the positive and negative aspects of implementation of CoMP in femtocell systems within LTE framework. The basic work done throughout this thesis is to investigate the parameter configuration and performance evaluation of downlink base station coordination in LTE femtocell scenario. 3GPP's technical specifications are applied for both macrocell and femtocell deployment. Parameter optimization and performance evaluation are examined for the users in the femtocell from different perspectives. |
