Carrier Aggregation (CA) is a promising technology that proposed by 3GPP in the latest LTE-Advanced (LTE-A) criterions in order to satisfy the future IMT-Advanced mobile networks demands. While CA allows aggregation of component carriers (CCs) dispersed within and transversely in diverse bands (intra/inter-band), CA is expected to offer a powerful boost to the user throughput in LTE-Advanced system. In addition, it will permit the achievement of the target peak data rates in excess of 1 Gbps in the downlink and 500 Mbps in the uplink in which the users has the right to use up to 100 MHz total of bandwidth. The mixture of LTE-A and LTE users within a multi-carrier LTE-A network may perhaps exist simultaneously. Each of them has various CA capabilities. The former has the ability to assign on multiple CCs, whereas the later can allocate on one CC. Moreover, they demand diverse QoS requirements which present new challenges to optimize the performance of LTE-Advanced system. Therefore, the choice of scheduling strategies plays a key role in guaranteeing desirable end to end system performance. The study of this paper will be beneficial for understanding the radio resource management (RRM) function with carrier aggregation feature. In addition, this article presents the Joint User- Proportional Fair scheduling scheme (JUS-PF) for resource allocation and its impacts on two deployment scenarios which are LTE-A users and mixture (LTE/LTE-A) users’ scenario in terms of average user throughput, cell edge user throughput, and fairness.
