Abstract
A method and network node for configuring a device-to-device (D2D) pair and a cellular wireless device, the cellular wireless device configured to have a direct link with a serving network device of a network cell in which the cellular wireless device resides. The method includes receiving Channel State Information (CSI) data for the D2D pair, a cellular wireless device, and at least one neighbor interference level, determining feasibility conditions for pairing the D2D pair and the cellular wireless device transmissions, determining a power allocation for the pairing of the D2D pair and 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.
