COMMUNICATION SYSTEM, BASE STATION DEVICE, AND MOBILE STATION DEVICE

摘要

Provided is a base station device comprising a scheduling means for scheduling a data transmitting period according to the intermittent reception period of a receiver. The scheduling means has functions to assign an MBMS service period and an action period of the receiver in an overlapping manner and to perform the transmission, when the MBMS service period and a data transmission period to the receiver overlap, by moving the data transmission period to the receiver, out of the MBMS service period. Also provided is a mobile station device for intermittent receptions, which has a function to perform receptions, when the intermittent reception period and the MBMS service period overlap, by enlarging the intermittent reception period. Alternatively, the scheduling means has a function to perform the transmission, when the MBMS service period and a data transmission period to the receiver overlap, by moving the subsequent data transmission period to the receiver, out of the MBMS service period. The mobile station device for intermittent receptions has a function to perform receptions, when the intermittent reception period and the MBMS service period overlap, by enlarging the subsequent intermittent reception period. Further provided is a system for performing the MBMS service with a mixed cell, which can avoid that the data cannot be transmitted for the action period in a DRX control of the mobile station device when the period for the MBMS service and the action period for the DRX control overlap.
