Abstract
A method for operating a station for serial data transmission using data frames in a communication network, configured to perform a carrier sense multiple access with collision avoidance (CSMA/CA) method, includes performing a first priority resolution for a specific first data frame to be transmitted on a communication channel, and establishing whether the specific first data frame to be transmitted has a highest priority. The method also includes performing a first backoff if the specific first data frame has the highest priority, transmitting the specific first data frame if the communication channel is free after the backoff, and raising the priority of the specific first data frame, in the absence of acknowledgement of the transmission of the specific data frame, to a priority level that is used exclusively for untransmitted data frames.
