Fairness and Transmission-Aware Caching and Delivery Policies in OFDMA-Based HetNets
Recently, cache-enabled heterogeneous cellular networks (C-HetNets) have been emerged as a promising solution for next-generation wireless networks to cope with exponentially increasing demands for high data rate and low latency multimedia services. In this paper, we design both the caching and the delivery policies in the downlink of an orthogonal frequency division multiple access (OFDMA)base...
متن کاملFairness-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 ...
متن کاملFairness-aware user selection and resource allocation in MISO-OFDMA
The problem of user selection and resource allocation for the downlink of wireless systems operating over a frequency-selective channel is investigated. It is assumed that the Base Station (BS) uses many antennas, whereas a single antenna is available to each user (Multiple Input Single Output—MISO case). To relieve heavy computational burden, a suboptimal, but efficient algorithm is devised th...
متن کاملFairness-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 ...
متن کاملBackhaul-Aware Decoupled Uplink and Downlink User Association, Subcarrier Allocation, and Power Control in FiWi HetNets
Decoupling the uplink and downlink user association improves the throughput of heterogeneous networks (HetNets) and balances the traffic load of macro- and small- base stations. Recently, fiber-wireless HetNets (FiWi-HetNets) have been considered as viable solutions for access networks. To improve the accuracy of user association and resource allocation algorithms in FiWi-HetNets, the capacity ...
