Section: 5.5.4.5 Event A4 (Neighbour becomes better than threshold)
Content: The UE shall: 1> consider the entering condition for this event to be satisfied when condition A4-1, as specified below, is fulfilled; 1> consider the leaving condition for this event to be satisfied when condition A4-2, as specified below, is fulfilled. Inequality A4-1 (Entering condition) Mn + Ofn + Ocn – Hys > Thresh Inequality A4-2 (Leaving condition) Mn + Ofn + Ocn + Hys < Thresh The variables in the formula are defined as follows: Mn is the measurement result of the neighbouring cell or the measurement result of serving PSCell (i.e., in case it is configured as candidate PSCell for CondEvent A4 evaluation) for CHO with candidate SCG(s) case, not taking into account any offsets. Ofn is the measurement object specific offset of the neighbour cell (i.e. offsetMO as defined within measObjectNR corresponding to the neighbour cell). Ocn is the measurement object specific offset of the neighbour cell (i.e. cellIndividualOffset as defined within measObjectNR corresponding to the neighbour cell, or cellIndividualOffset as defined within reportConfigNR), and set to zero if not configured for the neighbour cell. Hys is the hysteresis parameter for this event (i.e. hysteresis as defined within reportConfigNR for this event). Thresh is the threshold parameter for this event (i.e. a4-Threshold as defined within reportConfigNR for this event). Mn is expressed in dBm in case of RSRP, or in dB in case of RSRQ and RS-SINR. Ofn, Ocn, Hys are expressed in dB. Thresh is expressed in the same unit as Mn. NOTE: The definition of Event A4 also applies to CondEvent A4.
