ABSTRACT:
Pluralities of state update frames are defined. The base station is configured to transmit a state update data to instruct the mobile station to be set to either an active state or a suspended state, in the state update frames. The base station is configured to transmit a packet only to the mobile station that has been set to the active state by the state update data. The base station notifies the mobile station of a packet transmission by transmitting a control data including a data necessary to receive the packet, earlier than the packet transmission by a predetermined time. The mobile station is configured to receive the control data and the packet when being set to the active state, and is configured to not receive the control data and the packet when being set to the suspended state.
