Simulation of novel non-adjacent component carriers in LTE-Advanced

Abstract

Long Term Evolution-Advanced (LTE-A) is becoming the first choice of operators when constructing the new network infrastructure, because of its high throughput and low latency. Although the L TE-A can offer high speed data service as a benefit of wideband application, the large bandwidth also results in huge control signaling cost. Additionally the L TE bands may not be large enough in many countries to enable contiguous spectrum use. It is for this reason that non-contiguous LTE carrier aggregation work is on-going. LTE-Advanced carrier aggregation using non-contiguous spectrum, while possible is challenging in terms of its implementation. This paper presents a novel design of non-contiguous component carriers (CCs) in order to reach 120 MHz to have range of CC up to 100 MHz instead of maximum 80 MHz in the normal LTE-Advanced. The system is designed and implemented in two main cases; the first when it has four CCs broadcasted on the 100 MHz and the second case when the system has five CCs broadcasted on the 120 MHz. These two cases are analyzed to show the main performance of LTE-A after increasing the bandwidth of non-contiguous CCs.
