The demand for large-capacity, latency sensitive applications such as ultra-high-definition video transmission is increasing in wireless communication systems. In the next-generation wireless local area network (LAN), multi-access point (AP) coordination technique is attracting attention for the purpose of reducing collision probability and improving throughput. In high-demand applications such as ultra-high-definition video transmission, there is a problem that increasing the capacity of wireless communication does not necessarily lead directly to the realization of such applications. Therefore, to improve the number of applications that can be realized, the authors have studied application proportional fairness (APF), which is a radio resource control technique that improves the video throughput calculated based on whether the requirements for ultra-high-definition video transmission are satisfied. Since APF considers only application requirements and does not consider wireless quality, it cannot support multi-AP coordination. In this paper, we modify APF to take radio quality into account to support multi-AP coordination and demonstrate its effectiveness through computer simulations.
