1. A prioritization method for random access, the method comprising:
receiving a first packet flow for transmission, wherein the first packet flow is assigned a respective access category queue;
initiating a random access procedure for the first packet flow;
receiving a packet of a second packet flow for transmission, wherein the second packet flow is assigned an access category queue having priority over the access category queue assigned to the first packet flow;
issuing an indication configured to interrupt the random access procedure for the first packet flow; and
performing a random access procedure for the received packet of the second packet flow, wherein idle time slots previously sensed by the random access procedure for the first packet flow are considered as sensed also for the random access procedure for the second packet flow,
wherein issuing the indication configured to interrupt the random access procedure of the first packet flow is performed responsive to receiving the packet of the second packet flow.
