3GPP Spectrum Access Evolution Towards 5G
Journal Title: EAI Endorsed Transactions on Cognitive Communications - Year 2017, Vol 3, Issue 10
Abstract
The ever-increasing needs for more spectrum resources, and the emerging new Radio Access Technologies under the 5G umbrella add to the complexity of the Spectrum Toolbox in mobile networks landscape. This article covers 3GPP LTE evolution from Release 8 up to the Release 14, which deals with the LTE-Advanced Pro enhancements. A collection of available frequency bands, spectrum aggregation mechanisms, licensing and duplexing schemes, as well as spectrum sharing and refarming techniques is described. With such a classification, Spectrum Toolbox is defined and its evolution directions are discussed, with the opportunities and challenges of the individual features summarized. Studies on the new non-backwards compatible Radio Access Technology, as well as the new channel models for higher frequency bands are also covered. The presented Spectrum Toolbox is considered as a baseline for the introduction of the new air interface framework towards 5G ecosystem in the context of future mobile networks enhancements.

A novel spectrum allocation scheme in femtocell networks using improved graph theory
In this paper, we propose a novel spectrum allocation scheme by using graph coloring and taking QoS thresholds into account. The goal of our proposed method is to reduce interference among femtocells d...
Consensus-based Spectrum Sensing in Cognitive Radio Networks
In this work, we analyze a distributed cooperative spectrum sensing scheme where N secondary users (SUs) of a cognitive wireless net-work make a joint decision on the primary user (PU) presence based on an agreement reac...
A Method for Detecting Damage of Traffic Marks by Half Celestial Camera Attached to Cars
Roads are becoming deterioration in everywhere. In some places, traffic marks painted on roads are damaged thus needed to be updated. Municipalities must manage road condition and traffic marks (road painting). It is the...

Modeling of Time and Frequency Random Access Network and Throughput Capacity Analysis
In this paper, we model the random multi-user multi-channel access network by using the occupancy problem from probability theory, and we combine this with a network interference model in order to derive the achievable t...
