Next generation mobile communications system (5G)
Introduction to DOCOMO activities toward 5G
NTT DOCOMO proposes a future concept for the next generation mobile communications system (5G). Ongoing 5G experimental trials within DOCOMO and with world-wide vendors, efforts to the 5G Trial Sites and creation of new services using 5G with partner companies from various industries are also introduced.
Features ■ 5G provides a unified platform as a service enabler of new
communication such as augmented reality (AR) and tactile internet as well as a platform for IoT
■ 5G provides higher system capacity (1000x) & higher data rate (100x) than LTE
■ High system performance by communication of broader system bandwidth, network densification and exploitation of high frequency bands
■ Possible to provide rich content services (e.g., 4K video streaming) and advanced cloud services even in a highly dense traffic area
Application Scenarios ■ 5G is expected to provide stress-free mobile broadband
communication services even in heavily crowded traffic area such as train station at the center of a city or stadium
■ It is also expected to provide massive connectivity for IoT devices with wide connection coverage
■ Provision of ultra high reliable connection for application of mission critical operations; e.g., automatic driving, telemedicine, etc.
■ Stable Internet access regardless of places (e.g., urban or rural area)

Requirements & Targets of 5G 5G technical concept
Efforts to create new services using 5G
Higher data rate Reduced latency
Massive device connectivity
Energy savings & cost reductions
• 100x more connected devices(e.g., Crowded areas, M2M services)
• Energy savings for NW & terminals• Reduced NW costs, incl. backhaul
Higher systemcapacity
• RAN latency : < 1ms
• 1000x capacity/ km2
5G• Typical data rate: 100x faster(Peak data rate: > 10Gbps)
Existing frequency bands（Saturated）
Higher frequency bands(Higher data rates using wider bands)
Frequency
Wide(e.g. > 3GHz)
Super-wide(e.g. > 10GHz)
Connectivity and mobility maintained using lower frequency bands
Efficient high data rates transmission using higher/wider frequency bands+
Non-orthogonal multiple access (NOMA), etc.
Small cel ls, Massive MIMO,New RAT, etc.
Phantom cel l conceptRadio frame design for reduced latency & M2M, etc.
Further cellular enhancements
Exploitation of higher frequency bands
Frequency agnostic enhancements
