Abstract
Considering the needs of higher data rates and hence wider bandwidths for advanced mobile communication systems, 3GPP standardized carrier aggregation (CA) as one of the important technological components for fourth generation (4G) Long term evolution (LTE) advanced systems. Here the user equipments are assigned carrier component (CC) belonging to different (Interband contiguous/noncontiguous) or same spectrum bands (Intra-band contiguous/non-contiguous). The users share the radio resources as per different scheduling schemes like round robin(RR), proportional fair (PF), best channel quality indicator (CQI), max-min, edge prioritized, channel traffic aware etc. Every scheduler has its own characteristic and provides improvement in terms of throughput or fairness. This paper discusses the simulations carried out to study the performance of RR, PF and best CQI schedulers in an urban, CLSM (closed loop spatial multiplexing) environment using an LTE system level simulator.
