Abstract: To provide a wireless communication system, a base station device, a mobile station device, and a wireless communication control method that use a time division multiple access scheme, and enable a reduction in the power consumption of the base station. This wireless communication system performs communication by a time division multiple access (TDMA) scheme, and comprises a mobile station, and a base station that communicates with the mobile station and stops transmission of a signal including control information related to communication connection when there is no mobile station therearound.

Abstract: A communication control device comprises: a transmission unit which transmits, to each of a plurality of communication devices that perform communication using previously allocated communication resources, allocation information indicating the allocation of the communication resources to be used when the communication devices perform communication; and an intermediate state generation unit which, when the allocation of the communication resources to the respective communication devices is changed from a first allocation state to a second allocation state, generates an intermediate state indicating the allocation of the communication resources, on the basis of the first allocation state and the second allocation state, wherein the transmission unit transmits the allocation information to each of the communication devices such that the allocation changes from the first allocation state to the second allocation state via the intermediate state generated by the intermediate state generation unit.
