<P>PROBLEM TO BE SOLVED: To prevent the inconsistency of recognition between a base station device and a user device on whether or not prescribed information periodically transmitted by the user device is included in an up-shared data signal. <P>SOLUTION: The base station device includes a decoding part for an up-control signal and the up-shared data signal, and a reliability determination part for determining the reliability of the fact that the prescribed information is included in the periodically received up-control signal. When the timing of a period predetermined for the prescribed information and the reception timing of the up-shared data signal match, (1) whether or not to perform decoding assuming that the up-shared data signal includes the prescribed information is determined depending on whether or not the period is equal to or shorter than a radio frame length, and (2) when the period is longer than the radio frame length, whether or not to decode the up-shared data signal assuming that the up-shared data signal includes the prescribed information is determined depending on whether or not the reliability is higher than a prescribed value. <P>COPYRIGHT: (C)2011,JPO&INPIT |
