N2 - Long Term Evolution-Advanced (LTE-Advanced) supports both the use of Carrier Aggregation (CA) and the use of Heterogeneous Networks (HetNets). The main contribution of this paper was in modifying the LTE-Sim simulator to support the use of Disjoint Queue Scheduler (DQS) for a HetNet deployment of a macro-cell and a variable number of pico-cells. Then evaluating and comparing the Quality of Service (QoS) performance of the DQS based MLWDF, with DQS based EXP-Rule, and with SC MLWDF. The QoS performance evaluation is based upon the average users' throughput, Packet Loss Rate (PLR), and average packet delay. Experimental results showed that the use of the DQS can double the pico-cells' users throughput with a loss of fifth of the macro-cell's users throughput. The use of the DQS also increased the PLR and the packet delay values for both type of users. The use of both DQS schedulers, the DQS based MLWDF and DQS based EXP-Rule had a similar fluctuating performance in terms of average users' throughput and PLR. However, the the DQS based MLWDF had a slightly better performance in terms of packet delay.
