0  IntroductionWord‑p. 7

With enhancements such as HSDPA and Enhanced Uplink, the 3GPP radio-access technology will remain highly competitive for several years to come. However, to ensure competitiveness in an even longer time frame, the long-term evolution of the 3GPP radio-access technology is under study. Important parts of such a long-term evolution include reduced latency, higher user data rates, optimised support for packet services, improved system capacity and coverage, and reduced cost for the operator, while also reducing system complexity. In order to achieve this, evolutions of the radio interface as well as the radio network architecture are considered in the study item "Evolved UTRA and UTRAN" [1]. This document covers the Radio Interface Protocol Aspects of the study item.

1  ScopeWord‑p. 8

The purpose of this TR is to help TSG RAN WG2 to define and describe the radio interface protocol evolution under consideration for Evolved UTRA and UTRAN [1]. This activity involves the Radio Access Network work area of the 3GPP studies for evolution and has impacts both on the Mobile Equipment and Access Network of the 3GPP systems. This document is intended to gather the agreements rather than comparing different solutions.
