Deterministic Move Lists for Federal Incumbent Protection in the CBRS Band

Description

The 3.5 GHz citizens broadband radio service (CBRS) band in the U.S. is a key portion of mid-band spectrum shared between commercial operators and existing federal and non-federal incumbents. To protect the federal incumbents from harmful interference, a spectrum access system (SAS) is required to use a common, standardized algorithm, called the move list algorithm, to suspend transmissions of some CBRS devices (CBSDs) on channels in which the incumbent becomes active. However, the current reference move list implementation used for SAS testing is non-deterministic in that it uses a Monte Carlo estimate of the 95th percentile of the aggregate interference from CBSDs to the incumbent. This leads to uncertainty in move list results and in the aggregate interference check of the test. We propose to use upper and lower bounds on the aggregate interference distribution to compute deterministic move lists. These include the reference move list used by the testing system and an operational move list used by the SAS itself. We evaluate the performance of the proposed deterministic move lists using reference implementations of the standards and simulated CBSD deployments in the vicinity of federal incumbent dynamic protection areas (DPAs). The data include numerical results of the proposed deterministic move lists for a single protection point Pensacola DPA and forty offshore DPAs along the U.S. coasts. The data is associated with the article, "Deterministic Move Lists for Federal Incumbent Protection in the CBRS Band," T. T. Nguyen and M. R. Souryal, in IEEE Transactions on Cognitive Communications and Networking, Vol. 7, No. 3, September 2021.
