05.2017 – CETECOM released a new version of its Testing, Organization and Management Database (TOM). The new release includes the possibility to handle Carrier Aggregation scenarios covering 4DL test cases:
the covered specifications were recently released by 3GPP: V14.1.0 (2016-12)
5 test specifications – TS 36.521-1, TS 36.521-3, TS 36.523-1, TS 36.571-1 and ETSI EN 301 908-13 – have been covered
newly introduced bands and test cases (2DL, 3DL and 4DL) are included
Carrier Aggregation is a topic where the complexity is continuously growing. TOM was already capable of handling 3DL and 2DL test cases considering all the known complex rules. With the latest TOM release, TOM is now capable of handling 4DL test cases as well.
Additionally, two new rules have been identified in the 3GPP test specifications and are already available in TOM. These rules are optimization techniques, which will further reduce the testing requirements drastically having a major positive impact in many different ways. At the moment, there are about 80,000 valid Carrier Aggregation combinations and with all the known rules, a minimum of 50% reductions in overall testing requirements can easily be achieved.
