Abstract: An embodiment of a method for network resource management comprises performing joint traffic engineering and physical layer power control on a controller and using a routing and power control optimization process that comprises a combined alternating direction method of multipliers (ADMM) process and a power management process. First and second commands are generated at the controller according to optimization parameters determined by the routing and power control optimization process. The first and second commands are transmitted from the controller to nodes connected to the controller. The first commands are for modifying transmission parameters for links between nodes and the second commands are for modifying transmission parameters for connections between nodes and user devices.

Abstract: Transmit point (TP) associations can be assigned to user equipments (UEs) by including a TP association variable within a sum-utility function traditionally used for computing beamforming weight vector assignments. Accordingly, maximization of the sum-utility function obtains both TP associations and beamforming weight vector assignments. Additionally, the sum-utility function may be computed in accordance with channel statistics, rather than channel state information (CSI), thereby reducing coordinated multi-point transmission (CoMP) related overhead.
