| Summary: | The allocation of radio resources is one of the most critical functions
performed by the Radio Resource Management (RRM) mechanisms in the
downlink Long Term Evolution-Advanced (LTE-Advanced). Packet
scheduling concerns itself with allocation of these radio resources in an
intelligent manner such that system throughput/capacity can be maximized
whilst the required multimedia Quality of Service (QoS) is met. Majority of
the previous studies of packet scheduling algorithms for LTE-Advanced did
not take the effect of channel impairments into account. However, in real world
the channel impairments cannot be obliterated completely and have a direct
impact on the packet scheduling performance. As such, this work studies the
impact of channel impairments on packet scheduling performance in a
practical downlink LTE-Advanced. The simulation results obtained
demonstrate the efficacy of RM2 scheduling algorithm over other scheduling
algorithms in maximizing the system capacity and is more robust on the effect
of the cellular channel impairments. |
