Energy-efficient resource allocation for OFDMA two-way relay networks with imperfect CSI
Most of the existed works on the radio resource allocation (RRA) problem commonly assume the channel-state information (CSI) can be perfectly obtained by the transmission source. However, such assumption is not practical in the realistic wireless systems. In this work, we consider the practical implementation issues of resource allocation in orthogonal frequency division multiple access (OFDMA)...
متن کاملEnergy-efficient uplink resource allocation for IEEE 802.16j transparent-relay networks
The IEEE 802.16j standard is defined to enhance WiMAX networks with relay capacity. Under the transparent mode, existing studies only target at improving network throughput by increasing the transmission rates of mobile stations (MSs) and maximizing concurrent transmissions. However, using a higher transmission rate or allowing more concurrent transmissions could harm MSs in terms of their ener...
متن کاملEnergy-Efficient and QoS-ware Resource Allocation for Relay-enhanced OFDMA Wireless Cellular Networks
We focus on energy-efficient resource allocation with quality of service (QoS) guarantee for orthogonal frequency division multiple access (OFDMA) based wireless cellular networks with decode-andforward (DF) relaying. The joint transmission mode selection, subcarrier allocation and power control for the energy efficiency (EE) maximization problem is formulated as a non-convex and combinatorial ...
متن کاملPower-Minimizing Resource Allocation in Multiuser Cooperative Relay Communications
In this paper, we investigate the power-minimizing resource allocation problem in multiuser cooperative relay communication systems. A joint optimization problem involving subcarrier assignment, relay selection and power allocation is formulated. Since the problem cannot be solved directly, we decompose it into three subproblems. According to the equivalent channel gains and the target rates of...
متن کاملMultiuser Radio Resource Allocation for Multiservice Transmission in OFDMA-Based Cooperative Relay Networks
The problem of multiservice transmission in OFDMA-based cooperative relay networks is studied comprehensively. We propose a framework to adaptively allocate power, subcarriers, and data rate in OFDMA system to maximize spectral efficiency under the constraints of satisfying multiuser multiservices’ QoS requirements. Specifically, first we concentrate on the single-user scenario which considers ...
