Mikael Höök | EUCNC 2017 | © Ericsson 2017 | Page 6
› Requirements– Data rates– Traffic volume density– Mobility– Connection density– Device energy efficiency– Latency– Reliability– Network energy efficiency– Cost efficiency

› 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)
