Abstract
A radio base station making it possible to perform efficient scheduling of user terminals by reducing feedback information to be received from the user terminals is provided. A radio base station includes a position-related-information obtaining section configured to obtain position-related information indicating positional relationships among multiple user terminals. In addition, the radio base station includes a scheduler configured to determine user groups of the user terminals to be spatially multiplexed in the same time and frequency resources based on the position-related information obtained by the position-related-information obtaining section.
