Abstract:
This paper investigates the performance of packet scheduling in downlink LTE (Long Term Evolution) systems using Round Robin strategy in time domain and time and frequency domain. Two types of non-real time services are considered in the analysis performed, with and without priority set, as well as the limitation given by the physical downlink control channels (PDCCH) on the number of simultaneously scheduled users. Cell throughput, achievable user throughput and system capacity are evaluated in different scenarios with two mixed services, two packet scheduling approaches and priority impact on the generated traffic.
