intra-f meas in CM
Hi dears,
can anyone tell me hwo to find the threshold for starting intra-freq measurement in connected mode for HW ?
thx a lot

Re: intra-f meas in CM
the parameter is HoMeasComm.SMeasure. Default value HoMeasComm.SMeasureInd is off.
I don't know the the threshold applied when SMeasureInd is off, probably it always measure.

Re: intra-f meas in CM
LTE Intra Frequency Measurement
The UE triggers intra-frequency measurements if the one of the below conditions is fulfilled:
- The serving cell fulfils Srxlev < SIntraSearchP or Squal < SIntraSearchQ.
- The UE performs intra-frequency measurements regardless of the RX signal level or quality of the serving cell if CELLRESEL.SIntraSearchCfgInd or CELLRESEL.QQualMinCfgInd is set to NOT_CFG
Points:
o If CELLRESEL.SIntraSearchCfgInd is set to NOT_CFG, SIntraSearch is not broadcast in SIB3; if CELLRESEL.QQualMinCfgInd is set to NOT_CFG, SIntraSearchP and SIntraSearchQ are not broadcast in SIB3.
o If neither of SIntraSearchP nor SIntraSearchQ is specified, UE applies the default value (SIntraSearchP = Infinity, SIntraSearchQ = 0, based on 3GPP 36.331).
o When both SIntraSearch and SIntraSearchP are broadcast in SIB3, the UE takes the value of SIntraSearchP as that for SIntraSearchP.
SIntraSearch and SIntraSearchP are set by CELLRESEL.SIntraSearch
Intra-frequency Cell Reselection Criteria
In all cases, the UE shall reselect the new cell, only if the following conditions are met:
· The new cell is better ranked than the serving cell during a time interval TreselectionRAT (The cell reselection time for an intra-frequency neighboring cell is broadcast in the SIB3 and set by the CELLRESEL.TreselEutran parameter. The cell reselection time for an inter-frequency neighboring cell is broadcast in the SIB5 and set by the EUTRANINTERNFREQ.EutranReselTime parameter).
· The UE has camped on the serving cell for more than 1 second.

above is for idle mode isn't?

Indicates the threshold below which measurements on neighboring cells are started. If the signal quality of the serving cell exceeds this threshold, the UE is not required to perform intra-frequency, inter-frequency, or inter-RAT measurements, leading to reduced power consumption. The value -141 does not take effect, and is reserved for forward compatibility. If this parameter is set to -141, the value -140 is used as the threshold in implementation. |

Re: intra-f meas in CM
This procedure is for Cell Reselection in Idle Mode.
In Connected Mode the UE always measures the Intra-Frequency neighbors and based on the "A3 Event" settings it may trigger Intra-Frequency handover procedure.

dear do you know the name of the Intra Frequency HO counter in Nokia for LTE??
