7.10 Segmentation of RRC messages

Taught in 2. The six working groups and the line between them (TSG RAN — the group that specifies the radio, overview).

An RRC message may be segmented in case the size of the encoded RRC message PDU exceeds the maximum PDCP SDU size. Segmentation is performed in the RRC layer using a separate RRC PDU to carry each segment. The receiver reassembles the segments to form the complete RRC message. All segments of an RRC message are transmitted before sending another RRC message. Segmentation is supported in both uplink and downlink as specified in TS 38.331 [12].
