چکیده

In this letter, we study cell cooperation in the downlink OFDMA cellular networks. The proposed cooperation scheme is based on fractional frequency reuse (FFR), where a cooperation group consists of three sector antennas from three adjacent cells and the subchannels of each cooperation group are allocated coordinately to users. Simulation results demonstrate the effectiveness of the proposed schemes in terms of throughput and fairness. key words: multi-cell cooperation, OFDMA, FFR, ICI coordination, fairness

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 ...

Downlink Scheduling and Resource Management for Best Effort Service in TDD-OFDMA Cellular Networks

Throughput performance and geographical service fairness of best effort service used for downlink of a 802.16e based TDD-OFDMA sectored cellular networks are evaluated in conjunction with different scheduling schemes and frequency reuse plans. The OFDM systems are based on two multiple access schemes, which are the OFDM-TDM and OFDMA, and considered scheduling schemes are round robin, max C/I, ...

Power Control in Distributed Cooperative Cellular Networks

This paper addresses downlink cooperation at a system level. Cooperation between Base Stations is an alternative to macrodiversity to provide QoS continuity in case of mobility. We propose a Radio Resource Management strategy for the relay channel, made of relayed users identification, resource allocation and power control in an OFDMA-based system. Four scheduling methods are tested for power a...

A Survey on Resource Allocation in OFDMA Wireless Networks

OFDMA is the access scheme used in the third and fourth generation wireless cellular networks. Proper allocation of bandwidth and power is essential for ensuring the optimal performance and utilization of the resources in the OFDMA based cellular networks. The resource allocation in uplink direction and downlink directional will need different approaches. In uplink direction, different categori...
