LINE QUALITY REPORT METHOD, BASE STATION DEVICE, AND COMMUNICATION TERMINAL

摘要

There is provided a base station device for suppressing increase of current consumption at a communication terminal by a line quality information report used for resource allocation of a downstream line and increase of interference of the upstream line traffic. The base station device reports whether a terminal performing communication which may be delayed, to each communication terminal (ST301). When the communication terminal has received a report that it is a terminal performing communication whose delay is not permitted, it reports the line quality information all the report timings (ST302, ST307, ST310). On the other hand, when the terminal is decided to be a terminal performing communication which may be delayed, it reports line quality information on an preferable average line quality sub-carrier group once a predetermined report timing (ST303).
