Abstract

Carrier aggregation (CA) is a major technological advancement and a key enabler for the 3GPP in the Long Term Evolution (LTE) Advanced systems for the achievement of the IMTAdvanced requirements. Multiple component carrier with varying bandwidth, dispersed within inter bands and intra bands can be utilized through carrier aggregation in a simultaneous manner to achieve better coverage, high data rates and lower latency, and great user throughput. Despite the aspect of backward compatibility of CA, the introduction of the technology has required some changes from the LTE release 8 baseline as well as modification in functionality to the network radio resource function. This paper offers a review of the carrier aggregation technique with the functionality of Radio Resource Management (RRM) and requirements for the CA support. Current ongoing and recent research on scheduling algorithms and the aspects of RRM for LTE advanced in support of CA are reviewed. The paper also outlines the technical challenges presented in the packet scheduler design and for future research.
