BASE STATION DEVICE, MOBILE STATION, AND COMMUNICATION CONTROL METHOD

摘要

A base station performs communication with a mobile station in an upstream link by using a random access channel. The base station device includes: preamble sequence acquisition means which acquires one of preamble sequences used in the random access channel as a preamble sequence not used for signal transmission; and interference power estimation means which estimates an interference power by using the preamble sequence not used for signal transmission.
