A downlink radio resource allocation scheme based on ICI coordination for multi-cell OFDMA system is proposed. By dynamically determining frequency reuse factor, data rate of the users who have bad channel quality is increased. In order to reduce the packet delay of the users with high average packet arrival rate, the average packet arrival rate is used as a factor of the utility function in scheduling...
This paper addresses the margin adaptive (MA) problem in MIMO OFDMA multi-cell networks, when the transmitter only has statistical channel state information. Resource allocation is distributed within each base station. A distributed convergence criterion for power control is determined and included within iterative power allocation. An approximate analytical expression is obtained for the outage capacity,...
Some multihop cellular networks use spatial resource reuses for concurrent data transmission in a cell. However, there are no fundamental resource reuse policies am ong multiple hops to analyze the capacity of multihop iellulae networks. So, in this letter, we propose a basic resource reuse scheme by applying a general resource reuse scheme that is used for cellular networks to multihop cellular networks...
