3> include in "cell measurement event results" or in "cell measurement event results on secondary UL
frequency" all entries of the "cells recently triggered" in the corresponding variable
TRIGGERED_1E_EVENT in descending order according to the configured measurement quantity taking
into account the cell individual offset for each of those cells;
3> set the IE "measured results" and the IE "additional measured results", and/or the IE "measured results on
secondary UL frequency" and the IE "additional measured results on secondary UL frequency" according
to subclause 8.4.2, not taking into account the cell individual offset for each cell.
2> move all entries from "cells recently triggered" to "cells triggered" in the corresponding variable
TRIGGERED_1E_EVENT.
1> if "Measurement quantity" is "pathloss" and Equation 3 below is fulfilled for a primary CPICH, or if
"Measurement quantity" is "CPICH Ec/N0" or "CPICH RSCP", and Equation 4 below is fulfilled for a primary
CPICH; or
1> if a primary CPICH is no longer part of the cells allowed to trigger the event according to the "Triggering
condition 2":
2> if that primary CPICH is included in the "cells triggered" in the corresponding variable
TRIGGERED_1E_EVENT:
3> remove that primary CPICH and sent reports from "cells triggered" in the corresponding variable
TRIGGERED_1E_EVENT.
This event is only applicable to the CELL_DCH state. When the measurement is setup in CELL_DCH or upon
transition to CELL_DCH the UE shall:
1> if the "Triggering condition 2" includes active set cells:
2> include the primary CPICH of all cells in the current active set that fulfil the equations 1 or 2 according to the
"Measurement quantity" of event 1e into the "cells triggered" in the corresponding variable
TRIGGERED_1E_EVENT.

The variables in the formula are defined as follows:
M New is the measurement result of a cell that becomes better than an absolute threshold.
CIO New is the individual cell offset for the cell becoming better than the absolute threshold. Otherwise it is equal to
0.
T 1e is an absolute threshold.
H 1e is the hysteresis parameter for the event 1e.
If the measurement results are pathloss or CPICH-Ec/No then M New is expressed as ratios.
If the measurement result is CPICH-RSCP then M New is expressed in mW.
