Abstract

A wireless base station apparatus for performing wireless communication with a plurality of wireless communication apparatuses includes a communication processing unit for allocating wireless resources to the wireless communication apparatuses to perform wireless communication, a statistics processing unit for obtaining information related to communication status of the wireless communication apparatuses in wireless communication, and an intermittent arrangement determination unit for detecting a wireless communication apparatus to be allocated with wireless resource at intervals of a predetermined number of communication frames based on the information obtained. The communication processing unit intermittently allocates the same time slot to a plurality of wireless communication apparatuses detected by the intermittent arrangement determination unit at intervals of a predetermined number of communication frames.

Claims
