Basic Rules (3GPP TS 36.304)

Cell Selection (5.2.3.2)The cell selection criterion S is fulfilled when:

Srxlev > 0 AND Squal > 0 whereSrxlev = Qrxlevmeas – (Qrxlevmin + Qrxlevminoffset) – Pcompensation Squal = Qqualmeas – (Qqualmin + Qqualminoffset)

Measurement rules for cell re-selection (5.2.4.2)When evaluating Srxlev and Squal of non-serving cells for reselection purposes, the UE shall use parameters provided by the serving cell.

Intra frequency measurement de-activationSrxlev > SIntraSearchP and Squal > SIntraSearchQ

Inter Frequency and Inter RAT measurement de-activation for equal and Low priority cellSrxlev > SnonIntraSearchP and Squal > SnonIntraSearchQ

Inter Frequency and Inter RAT measurement de-activation for high priority cellMeasurement is mandatory

Inter-frequency and inter-RAT Cell Reselection criteria (5.2.4.5) If threshServingLowQ is provided in SIB3, cell reselection to a cell on high priority E-UTRAN frequency or inter RAT frequency than the serving will be performed if

A cell of a higher priority EUTRAN or UTRAN FDD RAT/ frequency fulfils Squal > ThreshX, HighQ during a time interval TreselectionRAT; or

A cell of a higher priority UTRAN TDD, GERAN or CDMA2000 RAT/ frequency fulfils Srxlev > ThreshX, HighP during a time interval TreselectionRAT; and

More than 1 second has elapsed since the UE camped on the current serving cell.

Otherwise, cell reselection to a cell on a higher priority E-UTRAN frequency or inter-RAT frequency than the serving frequency shall be performed if:

A cell of a higher priority RAT/ frequency fulfils Srxlev > ThreshX, HighP during a time interval TreselectionRAT; and

More than 1 second has elapsed since the UE camped on the current serving cell.

Cell reselection to a cell on an equal priority E-UTRAN frequency shall be based on ranking, Rank_neigh>Rank_serving

If threshServingLowQ is provided in SIB then cell on low priority E-UTRAN frequency or inter RAT frequency than the serving will be

The serving cell fulfils Squal < ThreshServing, LowQ and a cell of a lower priority EUTRAN or UTRAN FDD RAT/ frequency fulfils Squal > ThreshX, LowQ during a time interval TreselectionRAT; or

The serving cell fulfils Squal < ThreshServing, LowQ and a cell of a lower priority UTRAN TDD, GERAN or CDMA2000 RAT/ frequency fulfils Srxlev > ThreshX, LowP during a time interval TreselectionRAT; and

Otherwise, cell reselection to a cell on a lower priority E-UTRAN frequency or inter-RAT frequency than the serving frequency shall be performed if:
