RADIO COMMUNICATION SYSTEM, RADIO BASE STATION, RADIO COMMUNICATION TERMINAL, RADIO COMMUNICATION METHOD, AND A NON-TRANSITORY COMPUTER READABLE MEDIUM EMBODYING INSTRUCTIONS FOR CONTROLLING A DEVICE TO IMPLEMENT A CONTROL METHOD

摘要

When one base station forms a plurality of cells that use different frequency bands, a handover caused by movement between cells can be successfully performed with a high probability. A radio base station adapted to communicate with a radio communication terminal, comprising: a communication unit which performs a first communication with the radio communication terminal by using a first frequency, wherein the communication unit performs a second communication with the communication terminal by using a second frequency that is different from the first frequency; and a controller which performs a control, of at least one of a first power of the first communication and a second power of the second communication, based on a first power-related quality of the first communication and a second power-related quality of the second communication.
