1. Positioning in Non-Terrestrial Networks
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : In 5G communications, Non-terrestrial Network (NTN) is envisioned to complement Terrestrial Network (TN) to increase network availability, scalability and continuity. Positioning of User Equipment (UE) is critical for the operation of NTN. Currently, NTN uses Global Navigation Satellite System (GNSS) for positioning. READ MORE

2. Improved Precision Time Protocol with Relative Clock Phase Information
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : A common time reference among nodes is one of the key requirements in telecommunication, distributed control systems and industrial automation systems. For instance, 3GPP LTE TDD standard requires at least ± 1.5 µsec time accuracy among base stations in order to resolve uplink and downlink transmission. READ MORE
