摘要

An exemplary object is to provide a communication system that can flexibly determine whether carrier aggregation is applicable or not per UE. The communication system according to an exemplary embodiment of the invention includes a base station (10) that wirelessly communicates with a mobile station (20) by using at least one of a first frequency band and a second frequency band, the mobile station (20) being located concurrently in a cell (100) using a first frequency band and a cell (110) using a second frequency band, and a network device (30) that sends, to the base station (10), information to be used for determining a frequency band to be used.
