• New bands: 3.5 GHz, mmW(>28 GHz)
• Current LTE spectrum• New models: sharing
• New Radio (NR), eLTE• LTE-NR early drop • Massive MIMO, Active
Antennas• vRAN, Slicing, MEC
• Service-based architecture• Native NFV, PaaS• Dynamic Slicing, MEC

5G SPECTRUM
HARMONIZATION BY ITU-R IS ESSENTIAL
SPECTRUM TRADE-OFF
Each spectrum band fits better depending on the use cases and its needs.

5G ARCHITECTURE
gNB (CU/DU) SPLIT
Higher Layer Split shall be normative inStage 2 and Stage 3.In the meantime, RAN 3 recommends toprogress on Option 2 (TR 38.801).

5G RAN
3GPP FRAME STRUCTURE IN NR
CHALLENGES POSED BY TDD – NETWORKS SYNCHRONIZATION, UL COVERAGE, MOBILITY IN HIGH BANDS
Scalable numerology for OFDM Subcarriers

In TD-LTE, MNOs had to select aframe format.In NR, MNOs can also select a slotformat.
Mobility in high bands

5G RAN
MASSIVE MIMO AND BEAM MANAGEMENT
TX with connection is already stablished:NW transmit a specific reference signal for beam management;
UE detect the signal and perfom some measurement and send feedback to NW.
Scheduler also needs to considerthe QoS for each and every UE andbase the priority on this as well.
