Abstract:
1. A method of receiving Radio Link Control (RLC) Status Reports in a cellular radio system used for transmission of data between a sender and a receiver, said method comprising: receiving data on at least one first logical channel; receiving RLC status reports on a second logical channel separate from said at least one first logical channel, wherein the RLC status reports are sent in Protocol Data Unit (PDU) packets; determining whether a given RLC status report is the latest one based on checking a Transmission Sequence Number (TSN) of the PDU packet in which the given RLC status report is received; and delivering the given RLC status report to an RLC protocol processor directly upon reception of such a status report without buffering it in a reordering queue, based on the given RLC status report being the latest RLC status report for the given cellular radio link, and otherwise dropping the given received RLC status report rather than delivering it to the RLC protocol processor.
