Abstract
According to one embodiment, a wireless communication device includes: a wireless communicator configured to transmit and receive a signal; and controlling circuitry configured to detect a first wireless communication device through the wireless communicator. The wireless communicator is configured to transmit a control signal preset between the wireless communication device and the first wireless communication device to activate the first wireless communication device when the controlling circuitry has not detected the first wireless communication device.
Claims17
A wireless communication apparatus, comprising:
- wireless communication circuitry configured to transmit a transmission signal and receive a reception signal for communication;
- and
- controlling circuitry configured to communicate with a first wireless communication apparatus through the wireless communication circuitry to determine an identification of the first wireless communication apparatus, and,
- wherein the wireless communication circuitry is configured to transmit a control signal including the identification for activation to restart communication with the first wireless communication apparatus after the controlling circuitry fails to detect the first wireless communication apparatus wherein the control signal has a modulation scheme and a packet format that are different from a modulation scheme and a packet format of the transmission signal or the reception signal for communication.
A wireless communication apparatus, comprising:
- wireless communication circuitry configured to transmit a transmission signal and receive a reception signal for communication;
- a receiver configured to receive a control signal for activation;
- and
- controlling circuitry configured to control the wireless communication circuitry,
- wherein the controlling circuitry is configured to communicate with another wireless communication apparatus to determine an identification of the wireless communication apparatus,
- wherein the controlling circuitry is configured to set the wireless communication circuitry to a sleep state after the controlling circuitry detects null reception from the other wireless communication apparatus for a predetermined period, and
- wherein the controlling circuitry is configured to cancel the sleep state of the wireless communication circuitry after the controlling circuitry detects that the receiver receives the control signal including the identification wherein the control signal has a modulation scheme and a packet format that are different from a modulation scheme and a packet format of the transmission signal or the reception signal for communication.
A wireless communication method at least partially performed by wireless communication circuitry of a wireless communication apparatus, the method comprising:
- transmitting a transmission signal and receiving a reception signal for communication
- communicating with a first wireless communication apparatus through the wireless communication circuitry to determine an identification of the first wireless communication apparatus;
- and
- transmitting a control signal including the identification for activation of the first wireless communication apparatus to restart communication with the first wireless communication apparatus through the wireless communication circuitry after the wireless communication circuitry fails to detect the first wireless communication apparatus wherein the control signal has a modulation scheme and a packet format that are different from a modulation scheme and a packet format of the transmission signal or the reception signal for communication.
