Base station, mobile communication system and radio signal quality measurement method

摘要

A base station includes a received signal power measurement unit that calculates a radio signal power of a radio signal received from a mobile station which is connected by radio connection, a measurement period decision unit that decides a measurement period based on a first index representing a transmission rate of received data transmitted from the mobile station and one of a second index representing a resource assigned to the mobile station and a third index representing an amount of data buffered in the mobile station and to be transmitted, an interference power measurement unit that calculates an interference power over the measurement period, a received signal quality measurement unit that calculates signal quality of the radio signal based on the radio signal power and the interference power and a transmission power decision unit that decides a transmission power control value to the mobile station based on the signal quality.

1. A base station comprising:
a received signal power measurement unit that calculates a radio signal power of a radio signal received from a mobile station which is connected by radio connection; a measurement period decision unit that decides a measurement period which is to be used for calculating an interference power based on a first index representing a transmission rate of received data transmitted from the mobile station and one of a second index representing a resource assigned to the mobile station and a third index representing an amount of data buffered in the mobile station and to be transmitted; an interference power measurement unit that calculates an interference power over the decided measurement period; a received signal quality measurement unit that calculates signal quality of the radio signal received from the mobile station based on the radio signal power and the interference power; and a transmission power decision unit that decides a transmission power control value to the mobile station based on the signal quality.
