We develop a game theoretic framework for distributed resource allocation in the uplink of a cognitive radio network where secondary users (SUs) share the bandwidth with primary users (PUs). Each PU has a fixed data rate and applies power control to achieve its target SINR, while each SU jointly adjusts its data rate and transmit power by maximizing its utility. Since the SUs' total interference on...
In this paper, the performance of user fairness of resource allocation is considered in the downlink of relay-based OFDMA cellular systems. In the downlink transparent frame structure, the base stations (BSs) transmit in the first time subslot and the relay stations (RSs) transmit in the second time subslot. A non-cooperative power allocation game is defined for maximizing throughput and reducing...
This paper addresses the adaptive allocation of subcarrier, bit and power resources in the downlink of multicell OFDMA systems, where base stations allocate radio resources in a decentralized manner. Our algorithm uses discrete bit-loading values which is more applicable to the practical systems. Noncooperative game theoretic approach is adopted and we first only include the transmit power and throughput...
In this letter, we focus on a subcarrier and power allocation scheme in uplink OFDMA systems, where each user has not only the different power constraints, but also was limited by the different rates. A subcarrier and power allocation algorithm is proposed. In this algorithm, the subcarrier allocation is based on the normalized channel gain, and the power allocation is based on the pricing function,...
