Systems and methodologies of reducing overhead by designating various fields in an optimized Radio Link Control header. Depending on communication type (e.g., VoIP, non-VoIP) such fields include a combination of a Segment Indicator (SI—which indicates presence of a whole SDU at beginning or at an ending), a Sequence Number (SN), a Length Indicator (LI—which indicates length of a service data unit); a length for the length indicator (LLI—to enable a variable size for the LI and notify a receiver regarding such varying size); a Segment Offset (SO—to designate resegmented packets for lost protocol data units); a length indicator for the SO (LSO—to enable a variable size for the SO); and Last Segment Flag (LSF—for resegmentation of RLC protocol data units). |
