› Spectrum flexibility› Low latency configurations› Future-proof design› Ultra-lean design› Beam-centric design› Multi-connectivity› Interworking across spectrum bands

NR Design principles


› Requirements– Data rates– Traffic volume density– Mobility– Connection density– Device energy efficiency– Latency– Reliability– Network energy efficiency– Cost efficiency


Waveform and numerology

› Scaled LTE numerology – subcarier spacing Δf = 2n·15 kHz– Enables coexistence with NB-IoT and eMTC

Df Tcp

15 kHz 4.7 ms30 kHz 2.3 ms60 kHz 1.2 ms120 kHz 0.6 ms240 kHz 0.3 ms480 kHz 0.15 ms

15 kHz 30 kHz 60 kHz

› Bandwidth per carrier– Minimum carrier bandwidth – 5 MHz (< 6 GHz) and 40 MHz (> 6 GHz)– Maximum carrier bandwidth– 400 MHz (but at most 3300/6600 used subcarriers)

› Carrier Aggregation (CA) can be used for larger BWs



› Short scheduling units– Short regular slots – 125 ms at 60 kHz– “Mini slots” – arbitrary starting point and length within a slot

› Fast retransmissions– Fast ACK– Enabled by front-loaded DMRS/DCI and frequency-first

interleaving allowing for rapid data demodulation/decoding

› Uplink grant-free transmission– Fast access to channel– Preferably avoiding explicit time alignment (asynchronous

access)

Low latency



› Techniques for high reliability at low latency– Exploit all diversity levels– Robust coding and modulation– Robust channel state estimation– Multi-connectivity

› Fast re-transmissions key to preserve efficiency– Enabled by short symbol duration, mini-slots and tight

processing times

› No ”always-on” reference signals› Minimum amount of ”always-broadcast”

system information› ...

Today

› Reference signals› ”Broadcast” system information› ...



› Coverage– High frequencies– LoS vs. NLoS– With/wo beamforming– Urban vs. rural environment– Indoors, single/multi-floor

› Multi-TP seamless mobility› Peak-bitrate performance› Distributed MIMO & MU-MIMO› Propagation models validation
