Abstract
Embodiments of a method of operation of a power control coordinator to control transmission power of a plurality of Device-to-Device (D2D) pairs that co-exist with a Cellular User Equipment (CUE) that communicates with a base station of a cellular communications network comprises obtaining, for a particular time slot, delayed Network State Information (NSI) feedback from at least some of the plurality of D2D pairs. The method further comprises computing transmission powers for the D2D pairs, respectively, for the particular time slot using On-Line Convex Optimization (OCO) to solve an optimization problem that maximizes a weighted sum data rate of D2D pairs with a constraint of maximum expected interference to the base station. The method further comprises providing, to each D2D pair, an indication of the computed transmission power for the D2D pair for the particular time slot.
