Abstract:
In a wireless communication method of a wireless communication device to which a power management mode of a wireless LAN is applied and to which a parent device communicates, the method includes updating a listen interval of receiving a beacon signal from a parent device to be shorter than a current listen interval in response to a data transmission to the parent device; and periodically increasing the updated listen interval between the time span from the data transmission to a next data transmission, wherein reception of the beacon signal is carried out after switching from a doze state to an awake state.
