Abstract
In LTE-A, Carrier Aggregation allows the user to simultaneously transmit and receive data on multiple carriers resulting in increased throughputs. The Radio Resource Management (RRM) framework of Long Term Evolution (LTE) is thus modified, as not one but more Component Carriers (CCs) are assigned to the user. The CC selection mechanism has to be carefully implemented to maximize the load balancing and the spectral efficiency. In this work, a load balancing CC selection scheme is proposed which can be optimized for the Quality of Service (QoS) required by users. Feedback fluid queue model is developed to analyze and optimize the performance of the proposed scheme. It is concluded that the proposed scheme is capable of balancing the load across carriers.
