Device-to-device communication in a multi-cell network with perfect and imperfect CSI

摘要

A method and network device for configuring a D2D pair and a cellular wireless device. The method includes receiving a subset of complete CSI parameters for the D2D pair, the cellular wireless device, and at least one neighbor interference level, determining feasibility conditions for pairing the D2D pair and the cellular wireless device transmissions based at least on the received subset of CSI parameters, determining a power allocation for the pairing of the D2D pair the cellular wireless device transmissions, the power allocation being based on a sum rate of the D2D pair and cellular wireless device transmissions, and configuring the D2D pair and cellular wireless device based at least in part on the determined power allocation while limiting an inter-cell interference (ICI) generated in a plurality of neighboring cells. In one embodiment, the complete set of CSI parameters is received, rather than a subset.
