Approaches to spectrum sharing

IEEE Communications Magazine, 2005
Many complain about severe spectrum shortage. The shortage comes from outdated spectrum policies that allows for little sharing. Regulators have granted licenses that offer exclusive access to the spectrum. When these licensees are not transmitting, the spectrum sits idle.

Freemium Spectrum Sharing and Pricing

2021 International Conference on Software, Telecommunications and Computer Networks (SoftCOM), 2021
The pervasive virtualization of communication networks, including wireless networks, as well as the increasing proliferation of softwarized solutions in wireless communications pave the way for the highly flexible approach for spectrum sharing and pricing.

Competition with shared spectrum

2014 IEEE International Symposium on Dynamic Spectrum Access Networks (DYSPAN), 2014
Sharing spectrum has emerged as a promising way to meet the exploding demand for wireless data services. In this paper, we consider a scenario in which spectrum is shared between a primary and multiple secondary service providers, all of which are competing for a common pool of customers.

Investing in shared spectrum

2017 IEEE International Symposium on Dynamic Spectrum Access Networks (DySPAN), 2017
Sharing spectrum is a promising approach for expanding wireless access and increasing competition among wireless service providers. Indeed, this is a key motivation behind the recent regulations such as those for the 3.5 GHz band in the U.S. However, meeting this promise requires that service providers (SPs) have the incentives to invest in technology ...

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 Transmission Capacity

IEEE Transactions on Wireless Communications, 2011
This paper analyzes spectrum sharing between multiple systems. The efficiency of spectrum sharing is determined primarily by interference, which is a function of the spatial densities of the transmitters in systems dependent on the chosen spectrum sharing method.

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
