Spectrum sharing for 5G wireless systems (Spectrum sharing challenge)

2015 IEEE International Symposium on Dynamic Spectrum Access Networks (DySPAN), 2015
Understanding the performance of a spectrum sharing system by means of a hardware deployment is a challenging task. Motivated by this fact, we propose a prototype of a secondary system that co-exists with a primary system and simultaneously sustains the constraints defined by the regulatory.

Advanced Dynamic Channel Access Strategy in Spectrum Sharing 5G Systems

IEEE Wireless Communications, 2017
5G wireless communications aim at providing higher data rates, spectral efficiency, and energy efficiency than 4G. To achieve this target, the spectrum resource with low utilization is emptied out for 5G refarming.

Spectrum Sharing Exploiting Spectrum Database for LPWA

2019 Eleventh International Conference on Ubiquitous and Future Networks (ICUFN), 2019
In the most of current low power wide area (LPWA), packet collisions of uplink communication are controlled by setting duty cycle (DC), which controls the transmission cycle not to exceed the predefined fixed threshold. However, as the number of LPWA nodes increases, the fixed DC fatally increases the number of packet collisions and degrades the ...

Spectrum sharing for unlicensed bands

First IEEE International Symposium on New Frontiers in Dynamic Spectrum Access Networks, 2005. DySPAN 2005., 2005
We study a spectrum sharing problem in an unlicensed band where multiple systems coexist and interfere with each other. We first analyze a cooperative setting where all the systems collaborate to achieve a common goal. Under the assumptions that the systems communicate with Gaussian signals and treat interference as noise, we study the structure of the

Auction-Based Spectrum Sharing

Mobile Networks and Applications, 2006
We study auction mechanisms for sharing spectrum among a group of users, subject to a constraint on the interference temperature at a measurement point. The users access the channel using spread spectrum signaling and so interfere with each other. Each user receives a utility that is a function of the received signal-to-interference plus noise ratio ...

Spectrum Sharing Policy in Europe

2017
While the importance of harmonization on spectrum matters in the global scale is well known and the national regulatory authorities possess the power to govern the spectrum use within their territory, the regional level regulatory activities are important to bridge the gap between these two levels.

Accelerating Spectrum sharing technologies

IEEE Communications Magazine, 2013
Spectrum sharing potentially holds the promise of solving the emerging spectrum crisis. However, technology innovators face the conundrum of developing spectrum sharing technologies without the ability to experiment and test with real incumbent systems.

Competition and investment in shared spectrum

2015 49th Asilomar Conference on Signals, Systems and Computers, 2015
Meeting the exploding demand for wireless data services will require access to new wireless spectrum. However, the traditional approach of clearing spectrum and reallocating it is becoming increasingly difficult. This in turn has led to much interest in new approaches for sharing spectrum among different users, such as the those being currently ...

Spectrum Sharing for Drone Networks

IEEE Journal on Selected Areas in Communications, 2016
In this paper, we study spectrum sharing of drone small cells (DSCs) network modeled by the 3-D Poisson point process. This paper also investigates an underlay spectrum sharing between the 3-D DSCs network and traditional cellular networks modeled by 2-D Poisson point processes.
