The growing energy consumption driven by dramatic increases in the number of users and data usage becomes the key issue for operators in meeting demands on cost reduction and environmental impact targets. Deployment of low power base stations or relay stations in traditional macro cells is expected to reduce the total energy consumption of cellular radio networks. This paper investigates the cell's...
In the relay-enhanced cellular network, the target user will receive uncertain interference due to orthogonal transmission between BS and RS, which would make the traditional mechanisms of link adaptation and channel-aware scheduling invalid. In this paper, a novel resource scheduling scheme is proposed with a semi-static mode, in which dominant interferences for a target user are identified and inter-cell...
