    摘要: 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.

    摘要: 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.

    摘要: A method and apparatus for transmitting and receiving a digital signal using an orthogonal frequency division multiplexing (OFDM) communication system are provided. In this method, subcarriers are split into a plurality of subcarrier groups according to available frequency bandwidths and are respectively transmitted in a transmitting portion and the subcarrier groups are combined and are restored to the original signal in a receiving portion. Therefore, wireless resources may be used efficiently by combining with cognitive radio technology.
