Abstract

In a telecommunications system a larger higher layer data unit (SDU) is segmented into smaller segments on the lower layer (RLC).
A segmentation length information is used to indicate the lengths of the segments in a lower layer protocol data unit (PDU). Specific values of segmentation length information are employed to indicate, when necessary, special information about the upper layer data unit (SDU), such as whether the upper layer data unit ends in the current data segment in the lower layer PDU or continues to the next lower layer PDU. This information is needed in the receiver to correctly assemble the segmented data.
