WIRELESS BASE STATION, USER TERMINAL AND WIRELESS COMMUNICATION METHOD

摘要

The present invention is designed to realize link adaptation that is optimal for future radio communication systems. A radio base station is configured to select user terminals from user groups that are determined based on the channel gain of each user terminal, determine a user set to non-orthogonal-multiplex over an arbitrary radio resource, with transmission power that is allocated to each user group on a fixed basis, and transmit downlink signals to the user terminals of the user set, with the transmission power that is allocated to each user group.
