In this paper, we propose a coordinated scheduling scheme in downlink multi-cell Orthogonal Frequency Division Multiplexing Access (OFDMA) networks. Firstly, a novel decision tree algorithm is introduced to categorize users according to certain attribute parameters to improve system performance. To suppress inter-cluster interference, a filter is used at the receive. To mitigate intra-cluster interference...
Due to the time-varying nature of wireless channels, deterministic quality of service (QoS) is hard to guarantee in wireless networks. In this paper, by integrating information theory with the principle of effective capacity, we formulate an energy efficiency optimization problem with statistical QoS guarantee in the uplink of two-tier femtocell networks. To solve the problem, we introduce a Q-learning...
In this paper, we consider the problem of interference mitigation in the downlink of multicell networks via base station coordination. In this paper, a simple and efficient scheme for interference management based on potential game is proposed. The main emphasis of this paper is placed on the problem of users' quality of service (QoS) in order to maximize the efficient throughput of system. Meanwhile,...
In this paper, a novel resource allocation with QoS guarantee and fairness (RAQF) scheme is considered for orthogonal frequency division multiple access (OFDMA) two-way relay networks. Multiple source nodes exchange information with the assistance of an amplify-and-forward (AF) relay node (RN) in the presence of an eavesdropper. A joint power allocation, subchannel allocation and subchannel pairing...
A wireless network consisting of multiple sources communicating with the corresponding destination utilizing a single half-duplex relay is considered in this paper, while the sources are allowed to use the relay opportunistically. By integrating information theory with the concept of effective capacity, we propose a dynamic bandwidth allocation strategy over the wireless relay network based on the...
