At the 3GPP TSG RAN #26 meeting, the SI description on "Evolved UTRA and UTRAN" was approved.
The justification of the study item was, that with enhancements such as HSDPA and Enhanced Uplink, the 3GPP radioaccess technology will be highly competitive for several years. However, to ensure competitiveness in an even longer
time frame, i.e. for the next 10 years and beyond, a long-term evolution of the 3GPP radio-access technology needs to
Important parts of such a long-term evolution include reduced latency, higher user data rates, improved system capacity
and coverage, and reduced cost for the operator. In order to achieve this, an evolution of the radio interface as well as
the radio network architecture should be considered.
Considering a desire for even higher data rates and also taking into account future additional 3G spectrum allocations
the long-term 3GPP evolution should include an evolution towards support for wider transmission bandwidth than 5
MHz. At the same time, support for transmission bandwidths of 5MHz and less than 5MHz should be investigated in
order to allow for more flexibility in whichever frequency bands the system may be deployed
This TR is the report for the study item "Evolved UTRA and UTRAN". The objective of the study item is to develop a framework for the evolution of the 3GPP radio-access technology towards a high-data-rate, low-latency and packet-optimized radio access technology.
