Long Term Evolution Advanced (LTE-A) is a promising technology to achieve peak data rate up to 1Gbit/s in downlink and 500Mbit/s in uplink. As adjacent cells use the same frequency, interference between adjacent cells may degrade the bit rate at cell edges. Inter-Cell Interference Coordination based on carrier aggregation as well as Coordinated Multipoint (CoMP) transmission and reception is seen as promising technology for alleviating this degradation and improving the bit rate at cell edges.
This ICI can be mitigated with the help of different arrangements of frequency bands allocations and possibly with different transmission power distinguishing between the cell centre users and cell edge users.
In this thesis work different inter-cell interference mitigation and coordination are analyzed with different frequency allocation schemes, fractional frequency reuse, transmission power, and also different radio resource scheduling algorithms are evaluated to enhance cell edge performance, bandwidth efficiency and throughput.
Performance is evaluated in terms of SINR versus femtocell users, separation on distance from interfering cell. Performance is compared between conventional technique, CA technique and combined CA and CoMP.
