WIRELESS COMMUNICATION SYSTEM AND BASE STATION APPARATUS

摘要

In a system which performs wireless communication from an access point to stations using group identification information, the frequency of uses of group identification information that overlaps with that of another access point is reduced. An association between a station apparatus included in a group that is a target for simultaneous transmission and group identification information is stored, each station apparatus included in the group is notified of the group identification information, group identification information that is being used in the other access point apparatus is acquired, and if group identification information that is being used by the access point apparatus itself overlaps with the group identification information used by the other access point apparatus, the group identification information is changed so as to reduce the number of pieces of overlapping group identification information.
