Name	Type	Description
ILteRlcUm	module interface	Interface module for the Unacknowledged Mode (UM) of the Radio Link Control (RLC) layer. It defines gates to the Packet Data Convergence Protocol (PDCP) module and the LteRlcMux module. UM enables segmentation and/or concatenation of RLC Service Data Units (SDUs) before transmission, according to the size of the RLC Protocol Data Unit (PDU) decided by the Medium Access Control (MAC) layer. On the receiving side, RLC SDUs are reassembled before being forwarded to the Packet Data Convergence Protocol (PDCP) layer. In-sequence delivery of RLC SDUs is also guaranteed.
