We formulate an optimization problem for joint RU allocation and C-SR to maximize the throughput of a multi-AP coordinated WiFi system. The optimization problem is found to be a non-linear integer programming problem. We solve the problem for several network scenarios using an optimization tool. The joint design significantly improves throughput compared to a non-coordinated system. To reduce computational complexity, we also provide a heuristic solution to the problem. The proposed heuristic achieves throughput comparable to that of the computationally expensive optimization tool based solution approach.
