1. A method of a wireless personal network (WPAN) device, the method comprising:
- determining timing for changing a physical layer (PHY) communication mode of the WPAN device from a first communication mode to a second communication mode; and
transmitting information indicating the second communication mode as a parameter of a predetermined primitive from an upper layer of the WPAN device to a PHY layer, at the timing.

Abstract
Provided is an operation method of a wireless personal area network (WPAN) device. In the wireless personal area network (WPAN) device, the WPAN device supporting a plurality of physical layer (PHY) communication modes determines timing for changing a PHY communication mode, with reference to a beacon frame, in order to communicate with devices using various PHY communication modes, and transmits information indicating a PHY communication mode as a parameter of a primitive to a PHY layer, at the determined timing.
