To reduce the probability of collision of packet signals even if an amount of communication increases.
A control information extracting unit 66 receives information about a frame including at least a plurality of slots from another radio apparatus when access control processing to control communication between radio apparatuses is performed in the other radio apparatus. The control information extracting unit 66 produces a frame so as to be synchronized with a frame corresponding to the received information. A production unit 64 reports data in at least one of the plurality of slots included in the produced frame. A frame regulating unit 34 independently produces a frame when performing access control processing. The production unit 64 reports data in at least one of the slots of the independently produced frame and reports information about the independently produced frame in another slot.
