Co-Channel Interference Reduction Through Integrated Scheduling and Polarization Allocation for Fixed Cellular Systems

Fixed cellular systems, supporting a high level of scalability, may provide ubiquitous broadband access and fulfill the growing demand for high Internet access and a wide range of other broadband services. High performance and spectral efficiency are essential to accomplish the required Quality of Service (QoS) and the research for efficient co-channel interference (CCI) management is of great interest. This paper presents an integrated scheduling of the intracell and intercell transmissions and polarization alternation pattern so as to minimize the total amount of interference and enhance the service quality. The proposed scheme minimizes the impact of dominant interferers for the downlink of such a system and performs a significant increase of the maximum throughput per sector.
