The present document captures the results and findings from the study item "Study on physical layer enhancements for NR Ultra Reliable Low Latency Communication (URLLC)" [2][3]. The purpose of this TR is to document the baseline performance achievable with Rel-15 NR URLLC considering the prioritized URLLC use cases identified in [2][3], and to document the evaluation and findings of the potential enhancements for the prioritized URLLC use cases. However, this does not imply that NR Rel-16 URLLC is necessarily restricted to the identified use cases in [2][3]. This activity involves the Radio Access work area of the 3GPP studies and has potential impacts both on the Mobile Equipment and Access Network of the 3GPP systems. This document is a 'living' document, i.e. it is permanently updated and presented to TSG-RAN meetings.
