Artificial Intelligence began first with what at some point was called "Heuristics." Heuristics were just a set of rules that triggered multiple different examples of execution, for instance, searching and maximizing a tree with different rules, as the algorithm traversed a tree, and the in some ways mimicked "intelligence." In…

Measurement Reports in 4G LTE – Part 1

wincho

Measurement Reports in 4G LTE are a way for a UE ("User Equipment") or the mobile terminal to keep track of different signal strength measurements and report to the eNodeB if certain conditions are met. These conditions as reported as Measurement Reports assist the eNodeB in making handover decisions. A…
