Abstract
The LTE (Long Term Evolution) provides mobile users high throughput and low latency. In order to meet the requirements of future mobile data traffic, the 3rd Generation Partnership Project (3GPP) has introduced advanced features to the LTE system, including Carrier Aggregation (CA), enhanced MIMO (Multiple Input Multiple Output), and coordinated multipoint (CoMP). The enhanced system is called LTE-Advanced (LTE-A) system. This paper investigates Component Carrier Selection (CCS) and radio resource scheduling for uplink in LTE-A. In this work, a CCS algorithm depending on the pathloss and the slow fading of the radio signals is developed. Based on the channel conditions and the Quality of Service (QoS) requirements of the users, a Channel and QoS Aware (CQA) uplink scheduler is also designed, which is time and frequency domain decoupled. The simulation results demonstrate that the proposed schemes provide a good QoS and throughput performance as compared to other reference schemes.
