Method and apparatus for implementing LTE RLC header formats

摘要

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).

主权项

1. A method for optimizing Radio Link Control (RLC) headers comprising:
implementing, by one or more processors, a segment offset (SO) field in a RLC header to designate resegmented packets for lost protocol data units; implementing, by the one or more processors, a length indicator (LSO) for the SO field in the RLC header, to further accommodate a variable size of the SO field in the RLC header; and implementing, by the one or more processors, a Last Segment Flag (LSF) in the RLC header to identify a last segment of a protocol data unit (PDU).
