Abstract:
The disclosed embodiments relate to a method performed by an apparatus and also relate to an apparatus. The method includes transmitting to a communication device a burst including a subframe; receiving from the communication device a HARQ values associated with the subframe; and determining a random backoff contention window size based on the received HARQ values and also based on previously unused HARQ feedbacks. The apparatus is configured to perform the method steps described above.
