ABSTRACT:
There are in a network comprising at least one transmitter transmitting PDUs according to an ARQ protocol, one receiver receiving transmitted PDUs and acknowledging PDUs with FeedBack Information (FBI) message(s), and a Radio Resource Management (RRM) unit allocating resource based on a TDMA scheme providing series of Time Frames (TFs). The transmitter sends PDUs to the receiver and manages a transmitter ARQ sliding window. The receiver sends back one or more FBI messages to the transmitter and manages a receiver ARQ sliding window. The transmitter, upon reception of FBI message, updates its ARQ sliding window according to received feedback acknowledgement status information, and retransmits PDUs based on its ARQ sliding window.The RRM unit receives FBI messages and manages an extended ARQ sliding window updated according to them. The RRM unit allocates an amount of forward resource and an amount of backward resource, computed based on the extended ARQ sliding window, to the transmitter.
