1. A system for transmitting Protocol data units (PDUs), said system comprising:
a radio link control (RLC) layer for storing a RLC PDU list of RLC Protocol Data Units (PDUs) received from a ProtocolData Convergence Protocol (PDCP) layer, said control layer comprising:
a transmission block for transmission to a Media Access Layer (MAC) layer in a transmission event, wherein the transmission block is populated with a subset of PDUs in the RLC PDU list;
wherein when the transmission block is near a storage limit, the system scans the RLC PDU list one-by-one for a PDU that best fits a remaining grant of the transmission block, as determined based on sizes of the scanned PDUs, to complete population of the transmission block; and
a priority list for storing already scanned PDUs of the RLC PDU list that were greater in size than the remaining grant.
