Wireless communication system and wireless communication apparatus |
摘要 |
A wireless communication apparatus operates as a tributary station in a wireless communication system including a control station and the tributary station that perform a time division multiplex communication. The wireless communication apparatus includes a wireless unit that performs a wireless communication with the control station; an event processing unit that notifies of an event occurrence based on an occurrence of an event; and a control unit that controls a communication in synchronization with the control station by detecting a control signal from the control station. When received a notification of the event occurrence, the control unit starts a search operation to acquire the control signal transmitted by the control station. When received the control signal, the control unit transmits a message according to the event occurrence using a slot that has a predetermined position relationship with the slot in which the control signal is received. |

1. A wireless communication system comprising a control station and a tributary station that perform a time division multiplex communication, wherein
the tributary station includes: a first wireless unit that performs a wireless communication with the control station; an event processing unit that notifies of an event occurrence based on an occurrence of an event; and a first control unit that controls a communication in synchronization with the control station by detecting a control signal from the control station, the control station includes: a second wireless unit that performs the wireless communication with the tributary station; and a second control unit that transmits the control signal in a predetermined cycle in a slot with a frequency, and controls a reception of a message by which the message is received in a slot which has a predetermined position relationship with the slot in which the control signal is transmitted with a reception frequency determined based on the frequency with which the control signal has been transmitted, wherein when received a notification of the event occurrence, the first control unit of the tributary station starts a search operation to acquire the control signal transmitted by the control station, and when received the control signal in a slot, the first control unit transmits the message according to the event occurrence using a slot that has a predetermined position relationship with the slot in which the control signal is received. |
