Wireless USB host, wireless USB device, method of providing function of dual role device host, and method of performing function of dual role device host
A wireless USB host, a wireless USB device, a method of providing the function of a dual role device host, and a method of performing the function of the dual role device host are provided. The wireless USB host includes a searching unit which determines whether a wireless USB device can create a beacon and has transmitted a request to perform the role of a host based on a predetermined information packet received through a default link in a wireless USB point-to-point dual role device communication environment. The wireless USB host also includes a channel information packet creating unit which creates a channel information packet including at least one of packet synchronization information and channel time allocation information for setting a reverse link based on the determined result, and a transmitting/receiving unit which transmits the channel information packet based on the packet synchronization information, sets the reverse link to the wireless USB device based on the channel information packet, and performs data communication with the wireless USB device through the reverse link.
