the tfo should not influence the rxqual of the call, so that’s not where we should be looking at first.
i would love to have more inputs :
– what is the increase in the ratio and numbers of HO QUAL UL & DL (separately) ?
– what is the evolution of the RTCH Drop Rate in one of those cells.
– have you tried increasing the L_RXQUAL_DL_H_AMR and L_RXQUAL_UL_H_AMR (= not the PC but the HO thresholds), I suggested that in my previous post.
