WIRELESS COMMUNICATION METHOD FOR WIRELESS LAN SYSTEM, WIRELESS COMMUNICATION DEVICE AND WIRELESS TERMINAL
First Claim
1. 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 comprises:
- 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.

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.

10. A wireless communication device, comprising:
-
a communication section that conducts wireless communications with a parent device of a wireless LAN in a power management mode; and a communication control section that stores an information table defining three or more levels of interval of receiving a beacon signal from the parent device after switching from a doze state to an awake state, updates the current listen interval to a shorter listen interval according to the information table in response to a data transmission to the parent device and periodically increases the updated listen interval to follow the levels of the information table. - View Dependent Claims (11, 12, 13, 14)

15. A wireless communication device, comprising:
-
a communication section that conducts wireless communications with a parent device of a wireless LAN in a power management mode; and a control section that updates the interval of receiving a beacon signal from the parent device after switching from a doze state to an awake state to a value not greater than the beacon transmission interval of the parent device in response to a data transmission to the parent device and increments the interval of receiving a beacon signal by a defined value each time when a defined time passes between the time span from the data transmission to a next data transmission. - View Dependent Claims (16, 17)
