An arrangement, control unit, and method in a cellular telecommunication system for allocating packets in a packet data stream to different base stations for transmission to a mobile terminal. The control unit receives the packet data stream in a main queue and identifies a plurality of base stations having sufficient signal strength to communicate with the mobile terminal. A data splitter splits the data stream into a number of sub-streams containing different data packets from the packet data stream. The sub-streams are buffered in a number of sub-queues, each of which is connected to a different base station. Packets are allocated to the sub-queues to maintain equal numbers of packets in each sub-queue, or to maintain a specified quality of service level for each sub-stream. The base stations independently transmit their sub-streams to the mobile terminal. Error-control coding may be applied to the packets to enhance macro diversity benefits. |
