2 5G Technologies
3 3GPP 5G Standardization Phased approach Rel-15: the first 5G specs for 5G launch in 2020 and earlier Rel-16: for ITU submission and 5G enhancements Time plan for Release 15 5G specs was accelerated according to strong pressure from the market for the early 5G launch. Release 15 features Non-Stand Alone(NSA)and Stand Alone(SA) NSA L1/L2 to be completed by Dec Stand Alone to be completed by time to complete Rel-15 stage 3, i.e. June, 2017 embb and part of URLLC prioritized Both of below and above 6 GHz 2015 NTT DOCOMO, INC.

6 Core network for 5G EPC can host 5G RAN EPC is well suited for embb and mmtc type traffic Existing infrastructure can be used and also allows for early 5G introduction New Core can be defined if study proves it is beneficial For support of new services like ultra-reliable, low-latency communications, fixed wireless access But it should be supported in co-existence with (v)epc Should allow for independent evolution of RAN and CN CN (v)epc (v)epc New New Core Core slices (incl. (e.g. for for URLLC) URLLC) S1 S1 New I/F RAN LTE DU LTE DU 5G X2 5G DU LTE DU LTE DU 5G X2 5G DU Initial phase (around 2020) Later phase (around 202X?)
7 5G Trial Results
8 5G Experimental Trials w/ 13 vendors 2015 NTT DOCOMO, INC. All Rights Reserved. 8 5G experimental trials are being started since Q4 of 2014 Existing bands UHF bands Ex. 800MHz, 2GHz Exploitation of higher frequency bands Low SHF bands 3-6GHz High SHF bands 6-30GHz EHF bands > 30GHz Frequency Key devices/chip sets vendors System solution vendors Measuring instruments vendors
9 16 Observations from 5G Experimental Trials Capacity enhancement (Higher spectral efficiency) Using large scale MU-MIMO, compared to LTE 4x4 MIMO, about 5 times spectral efficiency improvement can be achieved Higher data rate 10Gbps is possible by the expected improvements in radio transmission capability and terminal chip performance Coverage for higher frequency bands In LOS environment, about 500m coverage could be provided In NLOS environment without reflectors, it is difficult to ensure coverage In NLOS environment, with reflectors, it is possible to ensure coverage In Urban areas where there are many reflectors, coverage can be ensured even in NLOS environment Blockage loss for higher frequency bands Compared to lower frequency bands, sudden degradation of performance is observed With reflectors, the level of degradation can be reduced
