Applies to following Test Cases:  \nMin Peak EIRP\nMax TRP\nReference Sensitivity\nACLR and SEM (no MU Upper Bound Applied)\nMin EIRP at 50t%-tile CDF and  EIS spherical coverage still under discussion.\nTT = 0.50 * MU (the upper bound of MU value used for TT calculation is 0.01ppm , 0.5 upper bound TT\/MU ratio)  Applies to following Test Cases:  \nFrequency error\nSince TT have dependency from MU, no TT value can be defined if the corresponding MU is not finalized (business as usual).\nTT values may decrease based on the experience on the field and when all parties will have more confidence in device performance\nThe TT values and the method to derive the TT defined until RAN5#85 (November 2019) for execution in any possible certification.
