Radio communication device, method for controlling radio communication, and radio communication system
First Claim
1. A radio communication device comprising:
- a receiver configured to receive a radio signal from a second radio communication device, the radio signal comprising data and indicating a level of urgency corresponding to the data; and
a processor coupled to the receiver, the processor configured to;
switch a communication mode associated with the radio communication device from a first communication mode to a second communication mode for a beacon period based on the level of urgency, wherein switching the communication mode comprises adding a competitive access period to the beacon period, whereintime division multiplexing access is used in the first communication mode and wherein competitive access is used for communication between the radio communication device and the second radio communication device during the competitive access period in the second communication mode; and
the processor is further configured to;
control the communication to be performed using competitive access when the level of urgency indicated by information is greater than or equal to a first threshold, andcontrol the communication to be performed using competitive access when the level of urgency indicated by the information is greater than or equal to a second threshold, is less than the first threshold, and is received a given number of times or more.

6. A radio communication device comprising:
-
a transmitter configured to transmit, at a transmission time in a beacon period, a radio signal to a second radio communication device according to a communication mode associated with the radio communication device at the transmission time, wherein the radio signal includes data and a state corresponding to the radio communication device, the state indicating a level of urgency associated with the data; and a processor coupled to the transmitter, configured to; switch, during the beacon period, the communication mode from a first communication mode to a second communication mode based on the level of urgency, wherein switching the communication mode comprises adding a competitive access period to the beacon period, wherein time division multiplexing access is used in the first communication mode and wherein competitive access is used for communication between the radio communication device and the second radio communication device during the competitive access period in the second transmission mode; and the processor is further configured to; control the communication to be performed using competitive access when the level of urgency indicated by information is greater than or equal to a first threshold, and control the communication to be performed using competitive access when the level of urgency indicated by the information is greater than or equal to a second threshold, is less than the first threshold, and is transmitted a given number of times or more. - View Dependent Claims (7)

8. A method for controlling radio communication, the method comprising:
-
receiving, at a radio communication device, a radio signal from a second radio communication device, the radio signal comprising data and indicating a level of urgency corresponding to the data; switching, by a processor, a communication mode associated with the radio communication device between a first communication mode and a second communication mode for a beacon period based on the level of urgency, wherein switching the communication mode comprises adding a competitive access period to the beacon period, wherein time division multiplexing access is used in the first communication mode and wherein competitive access is used for communication between the radio communication device and the second radio communication device during the competitive access period in the second communication mode; controlling the communication to be performed using competitive access when the level of urgency indicated by information is greater than or equal to a first threshold; and controlling the communication to be performed using competitive access when the level of urgency indicated by the information is greater than or equal to a second threshold, is less than the first threshold, and is received a given number of times or more. - View Dependent Claims (9, 10, 11, 12)
