Section: 5.7.7.3 Actions related to transmission of ULDedicatedMessageSegment message
Content: The UE shall segment the encoded RRC PDU based on the maximum supported size of a PDCP SDU specified in TS 38.323[ NR; Packet Data Convergence Protocol (PDCP) specification ]  [5]. UE shall minimize the number of segments and set the contents of the ULDedicatedMessageSegment messages as follows: 1> For each new UL DCCH message, set the segmentNumber to 0 for the first message segment and increment the segmentNumber for each subsequent RRC message segment; 1> set rrc-MessageSegmentContainer to include the segment of the UL DCCH message corresponding to the segmentNumber; 1> if the segment included in the rrc-MessageSegmentContainer is the last segment of the UL DCCH message: 2> set the rrc-MessageSegmentType to lastSegment; 1> else: 2> set the rrc-MessageSegmentType to notLastSegment; 1> submit all the ULDedicatedMessageSegment messages generated for the segmented RRC message to lower layers for transmission in ascending order based on the segmentNumber, upon which the procedure ends.
