Abstract
Provided are a method and an apparatus for performing a piconet coordinator (PNC) handover in a wireless personal area network (WPAN) in which devices using various PHY transmission modes coexist. A device that enters the WPAN transfers information about its PHY transmission mode to the PNC through an association request message so that a problem that conventional services are not provided to a user in the WPAN due to a difference in PHY transmission modes of the devices during the PNC handover can be solved.
