Does the signalling in LTE changes significantly from UMTS technology?

I wanted to know if the signalling flow in LTE, procedures, messages changes significantly from UMTS. For example connection establishment, call setup etc. I have checked the 3GPP documents but I am not quite sure.

This paper is really interesting in order to understand some basic differences from UMTS and LTE signalling in uplink procedures (channel access, and so on)
