Radio base station and communication control method

摘要

A second radio base station (1B) receives, from a first radio base station (1A), both interference information for each of a plurality of resource blocks and a traffic amount ratio. Then, the second radio base station (1B) corrects, based on the received traffic amount ratio, the also received interference information for each resource block. Further, the second radio base station (1B) controls, based on the interference information as corrected for each resource block, the transmission power of a radio terminal (2B).

主权项

1. A radio base station configured to perform radio communications with a radio terminal, comprising:
a transmission power controller configured to control transmission power of the radio terminal, wherein the transmission power controller controls the transmission power of the radio terminal based on interference information and load information, the interference information being information sent from a different radio base station and related to interference power received by the different radio base station, the load information being sent from the different radio base station and indicating a radio communication load in the different radio base station, the transmission power controller corrects a value representing the interference power indicated by the interference information based on a value representing the radio communication load indicated by the load information, and controls the transmission power of the radio terminal based on the corrected value of the interference information; wherein the transmission power controller corrects the interference information such that the interference information indicates smaller interference power as the radio communication load indicated by the load information is smaller, and controls the transmission power of the radio terminal based on the corrected interference information, and wherein the transmission power controller corrects the interference information such that the interference information indicates lower interference power than actual interference power when a value representing the radio communication load indicated by the load information is equal to or below a predetermined threshold, and controls the transmission power of the radio terminal based on the corrected interference information.
