Abstract

A method by a communication device accesses a shared communication channel using a contention based access protocol. The communication device is configured to transmit data streams with different transmission priorities via the shared communication channel with a first data stream having a higher transmission priority than a second data stream. A method includes observing whether the shared communication channel is available for transmission, where when the shared communication channel is available for transmission, and the communication device waits for the duration of a time interval randomly selected from a time range in which the shared communication channel is available for transmission before the transmission is started. A first time interval is selected from a first time range for the transmission of the first data stream, and a second time interval is selected from a second time range for the transmission of the second data stream wherein the second time range does not overlap with the first time range.
