COMMUNICATION DEVICE, COMMUNICATION SYSTEM AND COMMUNICATION METHOD
First Claim
1. A communication device comprising:
- a reception unit that receives a beacon signal including an identification number of a slave unit from a master unit;
a first assignment unit that performs an assignment of a first communication interval for receiving a signal from the master unit based on the number of identification numbers included in the beacon signal; and
a second assignment unit that performs an assignment of a second communication interval for transmitting a signal to the master unit within a rest of time calculated by subtracting the first communication interval and a non-communication interval, which is not used for a communication with the master unit, from a signal period which is a period of the beacon signal.

6. A communication system comprising:
-
a slave unit; and a mater unit that transmits a beacon signal including an identification number of the slave unit to the slave unit, wherein the slave unit includes; a first assignment unit that performs an assignment of a first communication interval for receiving a signal from the master unit based on the number of identification numbers included in the beacon signal; and a second assignment unit that performs an assignment of a second communication interval for transmitting a signal to the master unit within a rest of time calculated by subtracting the first communication interval and a non-communication interval, which is not used for a communication with the master unit, from a signal period which is a period of the beacon signal.

7. A communication method which performs a communication between a master unit and a slave unit by using a beacon signal including an identification number of the slave unit, the communication method comprising:
-
performing an assignment of a first communication interval for performing a signal transmission from the master unit to the slave unit based on the number of identification numbers included in the beacon signal; and performing an assignment of a second communication interval for performing a signal transmission from the slave unit to the master unit within a rest of time calculated by subtracting the first communication interval and a non-communication interval, which is not used for a communication with the master unit, from a signal period which is a period of the beacon signal.
