Carrier components assignment method for LTE and LTE-A systems based on user profile and application

Abstract

Increasing number of mobile users accesses large multimedia files (such as high definition audio, video, images, etc.) over the Internet. Therefore, the bandwidth demand for mobile Internet access is getting exponentially larger. To answer users' demand, Carrier Aggregation is proposed in LTE-A. In Carrier Aggregation, multi bands are used and the bands have supported different coverage. Therefore, mobile users can simultaneously connect only one or multi bands. Because of mobility of users, traffic types and assigned channel errors, the best available Carrier Components of each band should be assigned to each user in order to increase quality of services. Several works have been proposed in the literature to address Carrier Components assignment to mobile users by using Channel Quality Indicator, quality of service and traffic types in LTE systems. However, continuously increasing data requests of users forces the operators to manage traffic more intelligently. Therefore, we have proposed a novel Carrier Component assignment method which considers user profiles and traffic types to increase quality of services and experiences getting by mobile users. Results show that the proposed method uses system resources efficiently and can provide improved throughput rate in LTE and LTE-A systems. Our method will help service providers build efficient Carrier Component assignment services through considering user profile and traffic types.
