Embodiment Construction

[0025] Accordingly, the present invention is directed to an apparatus for controlling power of a wireless device and method thereof that substantially obviate one or more problems due to limitations and disadvantages of the related art.

[0026] An advantage of the present invention is to provide a WPAN coordinator that can reduce power consumption. Furthermore, power control of outstations is facilitated to reduce power consumption. Finally, inefficient operation and management of resources can be prevented.

[0027] Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.

[0028] To achieve these and other advantages, and in accor...

Abstract

A method of controlling the power consumption of a wireless station is disclosed. The present invention includes waking-up a coordinator in a sleep state, entering an awake state and if a signal for turning on a peripheral station is received in the awake state, transmitting an awake message to the peripheral station via a beacon signal during a beacon timeslot. Accordingly, the power consumption of a coordinator in a WPAN network may be reduced, power control by a peripheral station may be facilitated, and inefficient operation and management of the network may be prevented.

Description

technical field [0001] The present invention relates to a method of power control for communication between wireless stations in a wireless personal area network (WPAN), and more particularly, to a method of controlling power of various stations in a WPAN. Although the present invention is applicable to a wide variety of applications, it is particularly applicable to reducing coordinator power consumption in WPANs and facilitating power control of outstations in WPANs. Background technique [0002] Due to the rapid advancement of technology, the number of products incorporating digital technology is rapidly increasing. For example, various digital products including DVD players, cable set top boxes (STBs), digital video cassette recorders (DVCRs), digital TVs (DTVs), personal computers (PCs), etc. can be connected to the public network. These stations may implement various protocols to exchange audiovisual and other data with stations on the public network. [0003] The IE...
