Abstract
Provided is a method of allocating a channel time in a wireless personal area network (WPAN). In a WPAN where a parent piconet and at least one child piconet coexist, the method includes receiving a request frame transmitted from at least one of a plurality of child piconnet coordinators (PNCs) in order to request channel time allocation for data transmission, according to a common mode that is a PHY transmission mode commonly supported by a parent PNC and the child PNCs; and transmitting a beacon frame including channel time allocation information corresponding to the request frame to all the child PNCs of the WPAN.
