Radio communication system, radio base station, and mobile station control method

摘要

A radio base station includes: a table storage unit storing a table in which an E-TFCI indicating a transport format combination indicator of the physical data channel to be transmitted by a mobile station is associated with βed that is used to determine a SG and is an offset value of transmission power of the physical data channel to be transmitted by the mobile station; a parameter selector selecting the βed associated with the E-TFCI from the table; and a communication controller determining a SG based on the βed thus selected and an E-TFCI associated with the selected βed, and controlling transmission power of the mobile station by using the SG thus determined.

1. A radio base station for controlling a mobile station by using a transmission power ratio between an uplink physical data channel and an uplink physical control channel, the radio base station comprising:
a storage unit configured to store a table containing both a transport format combination indicator of the physical data channel transmitted by the mobile station and an associated transmission power offset that is an offset value of transmission power of the physical data channel to be transmitted by the mobile station and that is used to determine the transmission power ratio, the table being stored for each category of mobile stations; a selector configured to select, from the table corresponding the category of the mobile station, a transmission power offset associated with the transport format combination indicator; a base station controller configured to determine the transmission power ratio based on the transmission power offset selected by the selector and the transport format combination indicator associated with the transmission power offset thus selected, and control transmission power of the mobile station using the transmission power ratio thus determined; and an informing unit configured to inform the radio network controller of predetermined parameters to be used to determine the transmission power ratio, the predetermined parameters being determined based on the transmission power offset selected by the selector, and the transport format combination indicator associated with a selected transmission power offset.
