Disclosed is a relay transmission method for quality enhancement of service (QoS) in a wireless USB (WUSB) system. A relay transmission method for improving QoS between a WUSB host and a destination device includes the steps of: checking satisfaction of QoS (SoQ) relay values of a channel between the host and multiple devices different from the host and the destination device, and between the multiple devices and the destination device; selecting a device having the highest SoQ relay value among the multiple devices, and checking whether the SoQ relay value of the selected device is greater than a SoQ value of a direct route between the host and the destination device; deciding the selected device as a relay device when the SoQ value of the selected device is greater than the SoQ value of the direct route; and transmitting a data frame from the host to the destination device through the relay device. |
