Propelling 5G Forward – A closer look at Release 16.
3GPP Release 16 elevates 5G to the next level. New capabilities, efficiencies, flexibilities, deployments, and spectrum types/bands.
Enhancing 5G NR massive MIMO performance.
Release 16 MIMO Enhancements – Improving performance, efficiency, reliability
Enhanced multi-user MIMO
Reducing overhead and supporting Rank 4 MIMO, finer
quantization and PMI2 granularity by improving Type II CSI3
Multi-transmission/reception points
Improving reliability by allowing device to transmit and receive4 data to/from multiple base stations
Better multi-beam management
Supporting secondary cell beam failure recovery, interference-aware beam selection, overhead reduction
Improved power efficiency
Reducing PAPR (peak-to-average ratio) with improved uplink and downlink reference signal5
Extended uplink coverage
Achieving full-power uplink for all MIMO capable devices
Further enhancing device power efficiency.
Wakeup signal (WUS)
A low-power control channel to indicate activity or lack thereof in the corresponding DRX1 period
Enhanced cross-slot scheduling
Such as introducing explicit minimum scheduling offset parameter and better support for BWP2 switching
Low-power carrier aggregation control
Efficient activation and deactivation of secondary cell is controlled by the primary cell
Rel-16 new power saving techniques
Also standardized power model and evaluation methodology
Low power mode groups
Carriers can be configured with different DRX duration (e.g., shorter active time for mmWave vs. sub-7 GHz)
Device-assisted power saving
Devices can request preferred power saving parameters (e.g., DRX, # of carriers, max bandwidth)
Adaptive MIMO layer reduction
Supporting turning off transmit/receive chains (e.g., from 4 to 2) to save power
