The Evolution of LTE towards IMT-Advanced
Stefan Parkvall,David Astely +1 more
TL;DR: This paper provides a high-level overview of some technology components currently considered for the evolution of LTE, referred to as LTE-Advanced, and the IMT-Advanced requirements, which include extended spectrum flexibility to support up to 100MHz bandwidth.
Proceedings ArticleDOI
The 3G Long-Term Evolution - Radio Interface Concepts and Performance Evaluation
Erik Dahlman,Hannes Ekström,Anders Furuskär,Ylva Jading,Jonas Karlsson,Magnus Lundevall,Stefan Parkvall +6 more
TL;DR: 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.

Scheduling transmission of data over a transmission channel based on signal quality of a receiver channel
TL;DR: In this article, a base station schedules transmission of data packets to a user equipment unit (UE) over a downlink traffic channel when the uplink channel over which the UE sends ARQ type signals to the base station has a SIR greater than a predetermined threshold.
Journal ArticleDOI
Device-to-Device Communications for National Security and Public Safety
TL;DR: A clustering-procedure-based approach to the design of a system that integrates cellular and ad hoc operation modes depending on the availability of infrastructure nodes is proposed, and system simulations demonstrate the viability of the proposed design.
Proceedings ArticleDOI
The evolution of WCDMA towards higher speed downlink packet data access
TL;DR: It is shown how techniques such as fast link adaptation, fast hybrid ARQ and fast scheduling, among others, can be applied to WCDMA, leading to increased throughput, lower delays, and downlink peak rates in the order of 10 Mbit/s.
