Abstract  Abstract

According to the invention unique at the transmission side in a wireless communication system with a data flow and/or individual service indicator (ID) identifying the data streams (1 2) of the data packet whereby the receiving side of the data packet can be allocated to the corresponding data flow (1 2). Furthermore the transmitting side also embedded in each data stream (1 2) of the data packet sequence number (SN) in the original order of the data packets so that data streams are restored in the receiver (1 2) of the data packet. This has the advantage that data streams of a plurality of services (1 2) can use a common HARQ process. so it can reduce the receiving-side HARQ process is reserved memory.

According to the invention data packets of a data flow (1;2) are identified for transmission in a radiocommunication system with a data flow and/or individual service indicator (ID) enabling them to be allocated to the corresponding data flow (1;2) for reception.A sequence number (SN) for the data packets in each data flow (1;2) is added upon transmission to the data packet in order to reestablish the original order of the data packets of a data flow (12); the advantage thereof being that the data flows (12) of several services can use a common HARQ process whereupon the memory used for reception according to said HARQ process can be reduced.
