In Release 15 the basic support for URLLC was introduced with TTI structures for low latency as well as methods for
improved reliability. Further use cases with tighter requirements have been identified as important for NR evolution, in
addition to the need for enhancing the Release 15 enabled use cases.
The follow key use cases were identified to be considered:
Release 15 enabled use case improvements
Such as AR/VR (Entertainment industry)
New Release 16 use cases with higher requirements
Transport Industry, including the remote driving use case
Electrical Power Distribution
The objective of this study item is to investigate enhancements to URLLC (Ultra Reliable Low Latency
Communications), considering both FR1 and FR2 as well as TDD and FDD, with the already existing solutions for NR
as the baseline. The TR reports the results and findings from the study item, mainly on baseline performance achievable
with Rel-15 NR URLLC, layer 1 enhancements (including PDCCH enhancements, UCI enhancements, PUSCH
enhancements and enhancements to scheduling/HARQ/CSI processing timeline), UL inter UE Tx
prioritization/multiplexing and enhanced UL configured grant (grant free) transmissions.
