Capacity Enhancement with Joint Subchannel and Power Allocation Scheme for OFDMA Femtocell Networks
Efficient power and subchannel allocation methods are required for orthogonal frequency division multiple access (OFDMA) based femtocell networks to improve the capacity of the system. This paper considers a joint subchannel and power allocation algorithm with capacity maximization for downlink of an OFDMA based femtocell networks. In the proposed algorithm subchannel allocation is first perfor...
متن کاملA Cluster-based Resource Allocation Scheme for OFDMA Femtocell Networks ⋆
When femtocells are deployed densely, the co-tier and cross-tier interference greatly impair the network performance in spectrum-sharing orthogonal frequency-division multiple access (OFDMA) femtocell networks. In order to solve this problem efficiently, a cluster-based resource allocation algorithm is proposed. First, the interference graph of femto-tier is built based on the measurement repor...
متن کاملFair Resource Allocation for OFDMA Femtocell Networks with Macrocell Protection
We consider the joint subchannel allocation and power control problem for OFDMA femtocell networks in this paper. Specifically, we are interested in the fair resource sharing solution for users in each femtocell that maximizes the total minimum spectral efficiency of all femtocells subject to protection constraints for the prioritized macro users. Toward this end, we present the mathematical fo...
متن کاملOn Joint Sub-channel Allocation, Duplexing Mode Selection, and Power Control in Full-Duplex Co-Channel Femtocell Networks
As one of the promising approaches to increase the network capacity, Full-duplex (FD) communications have recently gained a remarkable attention. FD communication enables wireless nodes to simultaneously send and receive data through the same frequency band. Thanks to the recent achievements in the self-interference (SI) cancellation, this type of communication is expected to be potentially uti...
متن کاملPower and Subcarrier Allocation Scheme for Uplink OFDMA
In this contribution, we propose a power and subcarrier allocation scheme for uplink orthogonal frequency division multiple access (OFDMA) based on the capacity difference between different users. The scheme works iteratively and performs three major tasks. In the first step, the subcarrier with largest capacity difference of two active users is found. Then, the subcarrier selection of these tw...
