Abstract: A wireless communication device is operated to transmit information on a random access channel of a network node. Operation involves determining a first transmit power level for a transmission of the information, and selecting a first transmission time for the transmission of the information, wherein the selected first transmission time is determined by a number drawn from a first contention window, and wherein the selected first transmission time corresponds to a first amount of time delay that must elapse before transmission of the information occurs. The information is transmitted at the selected first transmission time, at the first transmit power level. When the transmitted information was not successfully received by the network node, a size of a second contention window is determined based on a size of the first contention window and on the first transmit power level.
