Data transmission technique for a contention channel

Abstract:

A technique for transmitting data (504) from a first station to a second station on a contention-based radio channel is described. As to a method aspect of the technique, the first station obtains a transmit identifier (506) for the first station from a set of transmit identifiers; transmits control information (502) including the transmit identifier (506) to the second station; and transmits the data (504) to the second station according to the control information (502), wherein the data includes a station identifier (508) for the first station, the station identifier (508) or a combination of the station identifier and the transmit identifier (506) being indicative of the first station.
