Abstract

3G Long Term Evolution (LTE) has emerged as a comprehensive evolution of the Universal Mobile Telecommunications System (UMTS). LTE system uses resource blocks which are the basic unit of exchanging information in both downlink and uplink. However, resource allocation scheme, which is a crucial component to guarantee quality of service, remains as an open issue. In this paper, we propose a novel cross-layer scheduling algorithm for LTE system that allocates resources, both as resource blocks and a modulation and coding scheme, among users with different traffic load. The algorithm minimizes the overall average packet delay and takes into account queueing theory, modulation and coding scheme supported by each user, channel condition, and available transmit power. Simulation results shows that the proposed algorithm provides substantial reduction in average delay compared to conventional algorithm.
