A Hybrid Scheme of MCS Selection and Spectrum Allocation for URLLC Traffic under Delay and Reliability Constraints [PDF]

open access: yesEntropy, 2022
The Ultra-Reliable Low-Latency Communication (URLLC) is expected to be an important feature of 5G and beyond networks. Supporting URLLC in a resource-efficient manner demands optimal Modulation and Coding Scheme (MCS) selection and spectrum allocation ...

On Dynamic Spectrum Allocation in Geo-Location Spectrum Sharing Systems

open access: yesIEEE Transactions on Mobile Computing, 2019
Spectrum sharing is a key technology to relieve the ever-increasing spectrum demand and realize the full potential of radio spectrum. In this paper, we study spectrum sharing between higher priority users and lower priority users under geo-location based spectrum sharing systems.

Double Auctions for Dynamic Spectrum Allocation [PDF]

open access: yesIEEE/ACM Transactions on Networking, 2014
Wireless spectrum is a precious resource and must be allocated and used efficiently. Conventional spectrum allocations let a government agency (e.g., FCC) sell a portion of spectrum to one provider. This is not only restrictive, but also limits spectrum reuse and may lead to significant under-utilization of spectrum.
