    摘要: PROBLEM TO BE SOLVED: To solve the problem with a system where a slave wireless terminal performs clock setting by capturing a beacon signal from a master wireless terminal and communication is synchronously performed, wherein a clock error may become considerable, when the time for the slave wireless terminal to capture the beacon is prolonged for power reduction.SOLUTION: A wireless communication apparatus is configured to periodically transmit a beacon signal for a communication partner to synchronize transmission and reception timing, and transmit a repeat frame containing an identification code multiple times in the reception timing of the communication partner if information to be transmitted is generated, and then transmit a main frame containing a data signal. In the wireless communication apparatus, the number of times of transmitting the repeat frame can be varied in accordance with a time difference between timing in which the information to be transmitted is generated and timing to receive the beacon signal for the communication partner to perform synchronous correction.
