Joint Transmission Scheduling and Power Allocation in CoMP via Geometric Programming
CoMP design carries out heuristic transmission scheduling and power allocation in two separate steps.In this paper,we formulate a joint optimization to integrate the two steps into a unified optimization framework.By proposing a novel powerfractionizing technique,binary optimization can be avoided and transmission scheduling can be incorporated into the power allocation process.The joint optimization problem is then transformed into a Signomial Programming(SP)problem,which is further approximated by iteratively solving a series of tractable Geometric Programming(GP)problems that can converge to at least a local optimum of the SP problem.Simulation results show that the proposed joint optimization outperforms the two-step approach by significantly improving the total edge user throughput with stable performance.
