Abstract—3GPP is in the process of defining the long-term evolution
(LTE) for 3G radio access, sometimes referred to as Super-
3G, in order to maintain the future competitiveness of 3G technology.
The main targets for this evolution concern increased
data rates, improved spectrum efficiency, improved coverage,
and reduced latency. Taken together these result in significantly
improved service provisioning and reduced operator costs in a
variety of traffic scenarios. This paper gives an overview of the
basic radio interface principles for the 3G long-term evolution
concept, including OFDM and advanced antenna solution, and
presents performance results indicating to what extent the requirements/
targets can be met. It is seen that the targets on threefold
user throughput and spectrum efficiency compared to basic
WCDMA can be fulfilled with the current working assumptions.
More advanced WCDMA systems, employing e.g. advanced antenna
solutions may however achieve similar performance gains.
Enhancements for reduced latency and IP optimized architectures
and protocols are further applicable to both LTE and
WCDMA.
