Abstract
A communication device includes: 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.
