RADIO COMMUNICATION APPARATUS

PROBLEM TO BE SOLVED: To solve the following problem: a communication system, such as Bluetooth(R) Low Energy, has disadvantages of long time required for connection establishment and hence increased power consumption at waiting operation because no adjustment of reception window and transmission timing between a master and a slave; therefore, it is conceivable that a transmission signal is completely received by increasing a reception operation interval as one of measures, which has a problem of further increased power consumption at continuous reception operation.SOLUTION: By learning a transmission interval of identification information in other radio communication apparatuses prior to connection operation, an unwasted reception window width is determined. By implementing a reception operation within the reception window width determined at connection, an unwasted reception operation is eliminated to reduce power consumption.
