New Value Creation through Collaboration with B2B2X Partners

Accelerating Digital Transformation to Create New Value▼Abstract

NTT is working to accelerate digital transformation to create new value by leveraging research results thatare the most advanced in the world. In particular, we believe that through collaboration with B2B2X(business-to-business-to-X) partners, we can combine the different strengths of NTT and our partners, which
will lead to the creation of value that can transform the world. In this article, the process of value creation—from the significance of collaboration and generating ideas to technical verification and promotion—isexplained.

Trends in Standardization of High-precision Time- andFrequency-synchronization Technology for Creating a 5GMobile Network▼Abstract
High-precision time- and frequency-synchronization technology has received worldwide attention in recentyears for its importance in creating a future fifth-generation (5G) mobile network. Consequently,
standardization of this technology is underway by ITU-T (International Telecommunication Union Telecommunication Standardization Sector) Study Group 15. This article introduces the function of timeand frequency-synchronization technology in 5G mobile networks and describes standardization trends
concerning technical requirements such as synchronization-network architecture and synchronization
accuracy.

Synchronous telecom requirements, clock devices, network architecture, test methods, etc., are specified.

Global Standardization Activities
Trends in Standardization of High-precision Time- and Frequency-synchronization Technology for
Creating a 5G Mobile Network

Frequency synchronization: ITU-T G.826x series
In addition to SyncE, frequency synchronization and transmission by PTP are specified, and mostrecommendations are completed. Discussions on high-precision frequency synchronization (EnhancedSync-E) equipment are underway.
Time and phase synchronization: ITU-T G.827x series
Basic requirements, devices, and profiles for time synchronization and transmission by IEEE1588 (PTP) arecompleted as planned.
Discussions on expansion and attaining high precision to handle diversification of network services are underway.
