Demystifying Secondary Radio Access Failures in 5G
Pages 114 - 120
Abstract
In this work, we have conducted a measurement study with three US operators to reveal three types of problematic failure handling on secondary radio access which have not been reported before. Compared to primary radio access failures, secondary radio access failures do not hurt radio access availability but significantly impact data performance, particularly when 5G is used as secondary radio access to boost throughput. Improper failure handling results in significant throughput loss, which is unnecessary in most instances. Datasets are available at https://github.com/mssn/scgfailure.

Recommendations
Efficient secondary access with intelligent spectrum sensing in cognitive radio networks
In cognitive radio networks, cooperative sensing can significantly improve the performance in detection of a primary user via secondary users SUs sharing their detection results. However, a large number of cooperative SUs may induce great sensing delay, ...
Secondary User Access Control in Cognitive Radio Networks
Spectrum sharing and aggregation among authorized secondary users (A-SUs) are important tasks in operating effective cognitive radio networks. Furthermore, in protecting spectrum sharing/aggregation against unauthorized secondary users (UA-SUs), ...
Efficient‐spectrum management based on localisation of primary user position towards 5G
Recent emergent technologies with the advent of 5G use cases have made it imperative for high demands in broadband radio spectrum as compared to the current 4G technologies and other outdated ones. This study introduces an efficient spectrum management ...
