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
First Claim
1. A wireless universal serial bus (USB) host comprising:
- a searching unit which searches whether a wireless USB device can create a beacon on the basis of a message received in a wireless USB point-to-point dual role device communication environment;
a control transfer packet creating unit which creates a control transfer packet comprising beacon synchronization information, channel time allocation information, and information on a transmission direction of data on the basis of the searched result; and
a transmitting/receiving unit which transmits the control transfer packet on the basis of the beacon synchronization information and performs data communication with the wireless USB device on the basis of the channel time allocation information and the information on the transmission direction of data.
