Abstract
A wireless universal serial bus (WUSB) host is configured to execute WUSB communication with at least one WUSB device. The WUSB host includes a transmitter, a receiver, an analyzer, an adaptive channel time allocation (CTA) setting unit, and a controller. The transmitter is configured to broadcast an initial control packet to the at least one WUSB device, where the control packet includes CTA information generated for the at least one WUSB device. The receiver is configured to receive a data packet from the at least one WUSB device in a packet receiving period indicated by the CTA information included in the control packet. The analyzer is configured to analyze at least one data packet received by the receiver and to determine whether the data packet has been normally received. The adaptive CTA setting unit is configured to adaptively determine, for each of the at least one WUSB device, an optimal packet receiving period in which the analyzer has determined that the data packet has been normally received, and to set the CTA information generated for the at least one WUSB device based on the optimal packet receiving period. The controller configured to generate a subsequent control packet including the CTA information set by the adaptive CTA setting unit.
