Resource allocation algorithms in LTE: A comparative analysis

As a breakthrough technology under 3GPP, LTE has attracted attention worldwide. Main features include enhanced peak data rates, lower delay, increased cell edge throughput. For an LTE system, serving a large number of users requires an efficient RRA algorithm which has not been standardized for the system and is still an open end for development. Researchers have proposed various algorithms some of which have become popular among network designers. A comparative study of some of these popular RRA algorithms has been carried out in this paper.
