Patent ID: 7623478

Claim:
A method of resource allocation in a network containing at least one transmitter associated to a transmitter ARQ unit, and configured to transmit PDUs according to an ARQ protocol, at least one receiver associated to a receiver ARQ unit, and configured to receive said transmitted PDUs and to acknowledge each of said PDUs by sending back to said transmitter one or more FeedBack Information (FBI) messages containing feedback acknowledgement status information indicating correct or incorrect reception of said transmitted PDUs, and a Radio Resource Management (RRM) unit configured to allocate resources to at least one of said transmitter and receiver based on a TDMA scheme providing a series of Time Frames (TFs), the method comprising: transmitting PDUs from said transmitter ARQ unit to said receiver and managing a transmitter ARQ sliding window having a bottom end corresponding to the oldest transmitted PDU not yet acknowledged and a top end corresponding to the next PDU to be transmitted; managing, upon reception of said PDUs by said receiver ARQ unit, a receiver ARQ sliding window having a bottom end corresponding to the oldest PDU not yet correctly received and a top end corresponding to the last correctly received PDU; sending back, after reception by said receiver ARQ unit of said PDUs, the FBI message or messages to the transmitter; and updating said transmitter ARQ sliding window according to feedback acknowledgement status information in said FBI message received by said transmitter ARQ unit; and retransmitting PDUs interpreted as not correctly received by the receiver based on said transmitter ARQ sliding window thus updated; receiving, using the RRM unit, said FBI messages and managing, using the RRM unit, an extended ARQ sliding window having a bottom end updated according to the feedback acknowledgement status information and a top end updated according to an amount of resources computed by the RRM unit for initial PDUs transmission; and allocating, using the RRM unit, at least one of an amount of forward resources to the transmitter for initial PDUs transmission, an amount of forward resources to the transmitter for PDUs retransmission, and an amount of feedback resources to the receiver for sending back the FBI messages, said amount of forward resources and said amount of feedback resources computed based on said extended ARQ sliding window.
