5G NR and LTE Downlink Coexistence Measurements Using Software-Defined Radios

August 20, 2024
Author(s)
Nadia Yoza Mitsuishi, Yao Ma, Jason Coder
With the rapid deployment of 5G New Radio (NR) in the sub-6 GHz frequency bands, cellular operators need to accommodate this new technology within the limited spectrum licensed to them, mostly occupied by 4G Long-Term Evolution (LTE). This poses the

ProSAS: An O-RAN Approach to Spectrum Sharing between NR and LTE

August 20, 2024
Author(s)
Sneihil Gopal, David Griffith, Richard Rouil, Chunmei Liu
The Open Radio Access Network (O-RAN), an industry-driven initiative utilizes intelligent Radio Access Network (RAN) controllers and open interfaces to facilitate efficient spectrum sharing between LTE and NR RANs. In this paper, we harness O-RAN's

Coexistence Testing: Comparing Conducted and Radiated Test Results

August 9, 2024
Author(s)
Susanna Mosleh, Nadia Yoza Mitsuishi, Jason Coder, Carl Sunderman
In an era of ubiquitous wireless devices, ensuring their coexistence in shared electromagnetic environments has become increasingly critical. This paper explores the dynamics of coexistence testing and compares two coexistence test environments outlined in

Cyclostationary Channel Power Measurements for CBRS Coexistence Assessment

March 31, 2024
Author(s)
Dan Kuester, Anthony Romaniello, PETER MATHYS
We present a compressive approach for channel power measurements in coexistence scenarios involving heterogeneous cyclostationary channel usage and an example application in the Citizens Broadband Radio Service (CBRS) band. The method leverages known cycle

ATIC: Automated Testbed for Interference Testing in Communication Systems

December 25, 2023
Author(s)
Michelle Pirrone, Keith Forsyth, Jordan Bernhardt, Dan Kuester, Aric Sanders, Duncan McGillivray, Adam Wunderlich
The proliferation of communication devices and systems has led to increasingly complex and dynamic spectral environments. This greatly impacts the operations of a multitude of organizations, including commercial entities, academic and non-commercial
