BASE STATION DEVICE AND COMMUNICATION CONTROL METHOD

摘要

A base station apparatus capable of communicating with a user equipment terminal using an uplink shared channel includes a calculation unit configured to calculate path loss between the user equipment terminal and the base station apparatus; an MCS selection unit configured to select an MCS level of the shared channel based on the path loss; a first offset calculation unit configured to calculate a transmission power offset for the shared channel based on both a decoding result of the uplink shared channel and a required uplink quality; a notification unit configured to notify the user equipment terminal of a difference between the transmission power offset for the shared channel and a transmission power offset retained by the user equipment terminal; and a reception unit configured to receive the shared channel from the user equipment terminal.
