Abstract:
1. A method of performing a piconet coordinator (PNC) handover, the PNC handover performed by a first device to a second device in a wireless personal area network (WPAN), the method comprising: determining whether the first device and the second device use a same Physical Layer (PHY) transmission mode by referring to information about the PHY transmission mode of the second device; deciding whether the first device can perform the PNC handover to the second device based on the determination result; performing the PNC handover to the second device based on the deciding result; and extracting information about the PHY transmission mode of the second device from an association request message that is received from the second device, wherein the extracting of information comprises extracting information about the PHY transmission mode of the second device from a device capability information element of the association request message, and wherein a PHY transmission mode of the first device is at least one of a single carrier (SC), on-off keying (OOK), and orthogonal frequency division multiplexing (OFDM).
