Large multimedia files (such as high definition audio, video, images, etc.) are accessed by an enormous number of mobile users over the Internet. Therefore, the bandwidth demand for mobile Internet access is increasing exponentially. To answer users' demand, carrier aggregation is proposed in LTE systems. In carrier aggregation, the best available one or more carrier components of each band must be assigned as primary and secondary carrier components to each user for efficient services. The previous papers have significantly improved the performance of LTE systems by using efficient carrier components assignment methods.
