Design and Implementation of Radio Link Control as a Part of the WCDMA Radio Interface Protocols by using SDL

The Universal Mobile Telecommunication System (UMTS) is the most powerful technology in the third generation (3G) mobile communication and it is the base for the 4G technology. The Wide band Code Division Multiple Accessing (WCDMA) is the radio access technique for the UMTS system. The Radio Link Control (RLC) Protocol is apart from layer 2 of WCDMA protocol architecture. In this paper, we present the RLC Protocol and focus on the Acknowledged Mode (AM) of RLC to explain its complicated functionality. The used methodology is the design, implementation, and verification of the functions of the AM RLC mode using SDL language. The AM RLC functions are confirmed and verified via the simulation results.
