TLDR
Promising technologies to fulfil 3G evolution targets are presented, including OFDM, multi-antenna solutions, evolved QoS and link layer concepts, and an evolved architecture, indicating that the requirements can indeed be reached using the proposed technologies.Abstract:
Work has started in the 3GPP to define a long-term evolution for 3G, sometimes referred to as super-3G, which will stretch the performance of 3G technology, thereby meeting user expectations in a 10-year perspective and beyond. The fundamental targets of this evolution - to further reduce user and operator costs and to improve service provisioning - will be met through improved coverage and system capacity as well as increased data rates and reduced latency. This article presents promising technologies to fulfil these targets, including OFDM, multi-antenna solutions, evolved QoS and link layer concepts, and an evolved architecture. Furthermore, the results of a performance evaluation are presented, indicating that the requirements can indeed be reached using the proposed technologies.read more

Single carrier FDMA for uplink wireless transmission
TL;DR: Among the possible subcarrier mapping approaches, it is found that localizedFDMA (LFDMA) with channel-dependent scheduling (CDS) results in higher throughput than interleaved FDMA (JFDMA), however, the PARR performance of IFDMA is better than that of LFDMA.

A future radio-access framework
David Astely,Erik Dahlman,Pål Frenger,Reiner Ludwig,Michael Meyer,Stefan Parkvall,Per Skillermark,Niclas Wiberg +7 more
TL;DR: A packet-centric approach is taken for the dataflow processing, implying that the scheduling mechanism and the retransmission protocol operate on complete packets rather than segments thereof, thus allowing for cross-layer optimization.

Broadband packet wireless access incorporating high-speed IP packet transmission
TL;DR: This paper proposes broadband packet wireless access focusing on the data link layer incorporating the IP-based core network, employing variable spreading factor-orthogonal frequency and code division multiplexing (VSF-OFCDM) with two-dimensional spreading that prioritizes time domain spreading in the forward link and multi-carrier/DS-CDMA in the reverse link for the system beyond IMT-2000.
