Fairness-aware radio resource management in downlink OFDMA cellular relay networks

Fairness-Aware Radio Resource Management in OFDMA Networks

In 4G technology especially LTE relaying and orthogonal frequency division multiple access (OFDMA) are widely accepted techniques in downlink. To obtain ubiquitous coverage with high data rate to user terminals even in difficult channel conditions (e.g. cell edge) a centralized RRM algorithm has been proposed for cellular fixed relay networks in OFDMA networks. The proposed method provides the ...

Radio Resource Management in OFDMA-based Cellular Relay Networks

The main objective of next-generation wireless networks is to accommodate the increasing user demand and to achieve a ubiquitous high-data-rate coverage so that mobile broadband services comparable to those of the wirelines are realized in a costefficient manner. This ambitious objective however faces several technical challenges in the conventional cellular architecture, e.g., the large pathlo...

Radio resource allocation in relay based OFDMA cellular networks

Fairness-Aware Caching and Radio Resource Allocation for the Downlink of Multi-Cell OFDMA Systems

The unprecedented growth of internet contents, specially social media, invoking a challenge to the load of cellular networks. In addition, nowadays, the demands of quality of experience (QoE) became a more practical norm in contrast of quality of service (QoS), in which downloading delay is an important factor of it. To satisfy this demand, we propose two resource allocation (RA) algorithms to ...

Downlink Radio Resource Allocation Scheme for Ofdma Cellular Network

This paper presents radio resource allocation scheme to maximize ergodic rates for OFDMA cellular network .Purpose behind this is to improve multiuser diversity. Objective of this paper is to improve multiuser diversity along with maximum ergodic rates.SNR is considered to maximize erotic rates, along with that packet size is also considered. In this paper an algorithm is proposed in which crit...
