Test Configurations

TPR are defined for the Test Environments

In addition, for Rural-eMBB test environment, average spectral efficiency value should meet the threshold values for LMLC evaluation configuration with ISD of 6000m and either evaluation configuration with ISD of 1732m

TSDSI Proposal for 3GPP Release 17

TSDSI entrusted with the role to “ track in a horizontal umbrella fashion the progress made on sub topics, within the different Work Areas (for 3GPP Release 17), that are important for NR deployment in developing countries and report status to TSG RAN”
