Abstract (in Japanese) (See Japanese page) 
(in English) While radio traffic continues to increase, available frequency bands are limited. It is important to increase radio resources in order to use limited bands efficiently. In this research, we consider high density cells allocation as an approach to increase wireless resources. The next-generation wireless LAN, IEEE 802.11ax realizes simultaneous transmission between cells by flexibly adjusting the carrier detection level of CSMA/CA (carrier sense multiple access with collision avoidance). On the other hand, the effect of simultaneous transmission may be decreased depending on some problems such as mixed standards environments or communication quality decreased. In this paper, we propose two novel multi radio interface control schemes by using Strategy management architecture for wireless resource optimization (WiSMA) which have been examined to realize dynamic wireless resource control with low control cost. We show the effect of each proposed scheme in the environment where the problems are mixed by computer simulation, and clarify that the effect can be derived by applying the proposed schemes according to the communication environment.
