Information reuse in dynamic spectrum access [PDF]
, 2013 Dynamic spectrum access (DSA), where the permission to use slices of radio spectrum is dynamically shifted (in time an in different geographical areas) across various communications services and applications, has been an area of interest from technical ...

Review and prospect on the research of dynamic spectrum sharing
Dianxin kexue, 2016 As one of the most efficient ways to alleviate the problem of spectrum scarcity，dynamic spectrum sharing has drawn worldwide attention. Firstly，the concept of dynamic spectrum sharing was briefly introduced.

Distributed Dynamic Spectrum Allocation for Secondary Users in a Vertical Spectrum Sharing Scenario [PDF]
, 2014 In this paper, we study the problem of distributed spectrum allocation under a vertical spectrum sharing scenario in a cognitive radio network. The secondary users share the spectrum licensed to the primary user by observing the activity statistics of ...

Next generation of radio spectrum management licensed shared access and the trade-off between static and dynamic efficiency [PDF]
, 2015 Increasing demand for access to the radio spectrum is setting the stage for a revision of existing radio spectrum management practices. A new wave of spectrum policy reforms can be envisaged, with a potential shift of policy focus from static to dynamic ...

Evolution Toward Data-Driven Spectrum Sharing: Opportunities and Challenges
IEEE Access, 2023 As the demand for wireless services continues to grow, the need for efficient and effective management of the radio frequency (RF) spectrum becomes increasingly important. A spectrum management approach based on data analysis and interpretation i.e. data-

The hinges of destiny: A decision analysis of spectrum users' choices [PDF]
, 2012 Dynamic spectrum access (DSA) has been a technological approach that has received considerable research attention over the past decade. At the same time, the relative paucity of deployed systems using some of these technologies speaks to either a ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT In pediatric patients, T‐cell lymphoblastic lymphoma (T‐LBL) survival exceeds 80%. Relapse remains associated with limited curative options. Frontline treatment is largely extrapolated from T‐cell acute lymphoblastic leukemia (T‐ALL) treatment, reflecting the ongoing debate, whether both entities represent distinct diseases or variants within ...
