June 2016 NGMN approved Trial and Test initiative (TTI) project which consists of four activity streams, respectively called Tests of Technology Building Blocks (TTBB), Proof of Concept (PoC), Inter-Operability and Precommercial Networks Trials.
It was agreed that the purpose of TTBB is to test the performance of individual technology building blocks (such as massive MIMO, beamforming for eMBB, waveforms, numerology, frame structure, channel coding, link adaptation for eMBB with the possibility of co-existence with URLLC and/or mMTC etc...) with proprietary equipment. The tests are expected to be performed in a lab environment as well as small-scale outdoor environments (with typically a single user in a cell for testing the link performance).
This document is technical report for TTBB that provides the full description for each of technology building blocks that have been identified as carrying higher priority by NGMN community, and the corresponding test results.
TTBB team believes that this document will present a guideline to all NGMN members and other external SDOs by enhancing the understanding on key technical features and their characteristics and eventually contribute to the timely introduction of 5G service into the telecommunication industry
