Radio communication system, radio base station, and communication control method for interference reduction

摘要

An LTE base station (10-1) incorporates an initiation time for the measurement of the amount of interference and a measurement duration, which act as time information relating to the timing of the occurrence of interference, into load information (LI) messages, which act as interference control information, and transmits the LI messages to another LTE base station. Meanwhile, when the LTE base station (10-1) receives LI messages from another LTE base station, of the received LI messages, only LI messages in which the corresponding measurement duration period overlaps with the validity period are aggregated, and on the basis of the aggregate result, interference reduction control is carried out.

主权项

1. A radio communication system including a first radio base station and a second radio base station, wherein
the first radio base station comprises: a transmission unit configured to transmit interference control information to the second radio base station, the interference control information for reducing interference including time information indicating an interference occurrence time, and the second radio base station comprises: a reception unit configured to receive the interference control information from the first radio base station; and an interference control unit configured to perform weighting of the interference control information according to a degree of overlapping between a time zone indicated by the time information and a time zone regarded as valid.
