A detailed technical description of the air interface signalling protocols employed in LTE. This includes the layer 3 Radio Resource Control (RRC) and layer 2 Packet data Convergence Protocol (PDCP), Radio Link Control (RLC) and Medium Access Control (MAC) protocols. The set of messages and functions supported by each protocol is examined in detail.
Who would benefit
This course would benefit engineers involved with equipment design, operation, and optimization or monitoring of the LTE radio link.
An engineering background with some knowledge of digital radio systems and general radio principles and techniques is assumed. A basic understanding of LTE and experience of 2G or 3G systems would be beneficial.
