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,wherein the timing for changing the PHY communication mode is a point at which a channel time allocated to the WPAN starts, andwherein the first communication mode and the second communication mode are the PHY communication mode, and one of the first communication mode and the second communication mode is one of a single carrier (SC) method and an orthogonal frequency division multiplexing (OFDM) method.
