In response, SA WG1 has agreed the attached Release 15 CRs - to align the URLLC KPI's table in TS 22.261 with the stage 2 agreements including the expected target RAN capabilities; - to specify URLLC KPIs applicable to EPS in TS 22.278 which align with stage 2 agreements including the expected target RAN capabilities. In addition, it has also been clarified that the requirements for 5G E-UTRA-NR Dual Connectivity connected to EPC are included in TS 22.278.
