Event A1 (Serving becomes better than threshold)

Inequality A1-1 (Entering condition)
$Ms-Hys>thresh$
Inequality A1-2 (Leaving condition)
$Ms-Hys < thresh$

Ms is the measurement result of the serving cell, not taking into account any offsets.
Hys is the hysteresis parameter for this event (i.e. hysteresis as defined within reportConfigEUTRA for this event).
Thresh is the threshold parameter for this event (i.e. a1-Threshold as defined within reportConfigEUTRA for this event).
Ms is expressed in dBm in case of RSRP, or in dB in case of RSRQ and RS-SINR.
Hys is expressed in dB.
Thresh is expressed in the same unit as Ms.

Event A2 (Serving becomes worse than threshold)

Inequality A2-1 (Entering condition)
$Ms+Hys<thresh$
Inequality A2-2 (Leaving condition)
$Ms-Hys > thresh$

Event A3 (Neighbour becomes offset better than PCell/ PSCell)

Inequality A3-1 (Entering condition)
$Mn+Ofn+Ocn-Hys>Mp+Ofp+Ocp+Off$
Inequality A3-2 (Leaving condition)
$Mn+Ofn+Ocn+Hys>Mp+Ofp+Ocp+Off$

Mn is the measurement result of the neighbouring cell, not taking into account any offsets.
Ofn is the frequency specific offset of the frequency of the neighbour cell (i.e. offsetFreq as defined within measObjectEUTRA corresponding to the frequency of the neighbour cell).
Ocn is the cell specific offset of the neighbour cell (i.e. cellIndividualOffset as defined within measObjectEUTRA corresponding to the frequency of the neighbour cell), and set to zero if not configured for the neighbour cell.
Mp is the measurement result of the PCell/ PSCell, not taking into account any offsets.
Ofp is the frequency specific offset of the frequency of the PCell/ PSCell (i.e. offsetFreq as defined within measObjectEUTRA corresponding to the frequency of the PCell/ PSCell).
Ocp is the cell specific offset of the PCell/ PSCell (i.e. cellIndividualOffset as defined within measObjectEUTRA corresponding to the frequency of the PCell/ PSCell), and is set to zero if not configured for the PCell/ PSCell.
Hys is the hysteresis parameter for this event (i.e. hysteresis as defined within reportConfigEUTRA for this event).
Off is the offset parameter for this event (i.e. a3-Offset as defined within reportConfigEUTRA for this event).
Mn, Mp are expressed in dBm in case of RSRP, or in dB in case of RSRQ and RS-SINR.
Ofn, Ocn, Ofp, Ocp, Hys, Off are expressed in dB.

Inequality A5-3 (Leaving condition 1)
$Mp-Hys>Thresh1$
Inequality A5-4 (Leaving condition 2)
$Mn+Ofn+Ocn+Hys<Thresh2$

Mp is the measurement result of the PCell/ PSCell, not taking into account any offsets.
Mn is the measurement result of the neighbouring cell, not taking into account any offsets.
Ofn is the frequency specific offset of the frequency of the neighbour cell (i.e. offsetFreq as defined within measObjectEUTRA corresponding to the frequency of the neighbour cell).
Ocn is the cell specific offset of the neighbour cell (i.e. cellIndividualOffset as defined within measObjectEUTRA corresponding to the frequency of the neighbour cell), 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 reportConfigEUTRA for this event).
Thresh1 is the threshold parameter for this event (i.e. a5-Threshold1 as defined within reportConfigEUTRA for this event).
Thresh2 is the threshold parameter for this event (i.e. a5-Threshold2 as defined within reportConfigEUTRA for this event).
Mn, Mp are expressed in dBm in case of RSRP, or in dB in case of RSRQ and RS-SINR.
Ofn, Ocn, Hys are expressed in dB.
