Provided is a method and apparatus for wirelessly transmitting Universal Serial Bus (USB) application data by using an Enhanced Distributed Channel Access (EDCA) scheme that uses one or more Access Channels (ACs) having different priorities. The method includes receiving one or more USB application data from an USB application, dynamically assigning an AC through which the USB application data is to be transmitted, and transmitting the USB application data through the assigned AC.

Scheme for supporting wireless transmission taking into account QoS of USB application data

The present disclosure provides a method for managing buffers of a device for Universal Serial Bus (USB) communication in a wireless environment. The method includes determining respective current data storage levels of transmit buffers that store different types of data for USB communication; comparing the respective current data storage levels of the transmit buffers with corresponding respective predetermined threshold levels; and controlling an input rate or output rate of a first transmit buffer if it is determined based on the comparison that the first transmit buffer has a current data storage level that exceeds a predetermined threshold level.
