The UE reports measurement information in accordance with the measurement configuration as provided by E-UTRAN. E-UTRAN provides the measurement configuration applicable for a UE in RRC_CONNECTED by means of dedicated signalling, i.e. using the RRC CONNECTION RECONFIGURATION message
The UE can be requested to perform the following types of measurements:
- Intra-frequency measurements: Measurements at the downlink carrier frequency (ies) of the serving cell(s).
- Inter-frequency measurements: Measurements at frequencies that differ from any of the downlink carrier frequency (ies) of the serving cell(s).
- Inter-RAT measurements of UTRA frequencies or of GERAN frequencies or of CDMA2000 HRPD or CDMA2000 1xRTT frequencies
Example: MEASUREMENT REPORT message – Intra E-UTRAN measurements
Example: MEASUREMENT REPORT message – InterRAT measurements

Hi ,
ReplyDeletei'd like to thank you for your efforts,
regards the above measurements the RSRP & RSRQ is absolute values how can we get the dbm values
is it like
RSRP (-140 + 56) = - 84 dbm
RSRQ (-40 + 26) = -14 db
thnkx in advance.
Hi,
ReplyDeleteAccording to Table 9.1.4-1 (TS 36.133), RSRP of 56 = -85 ≤ RSRP < -84 dBm
and
According to Table 9.1.7-1 (TS 36.133), RSRQ of 26 = -7 ≤ RSRQ < -6.5 dB
Do you agree?
Hello
DeleteHow to identify the primary cell?
For example I see the following below however no PCI or frequency identifier.
message: c1: measurementReport: MeasurementReport ::= {
criticalExtensions: c1: measurementReport-r8: MeasurementReport-r8-IEs ::= {
measResults: MeasResults ::= {
measId: 2
measResultPCell: measResultPCell ::= {
rsrpResult: 21
rsrqResult: 10
thank you for your prompt response.
ReplyDeleteand i'm totally agree with you
BR,

Hi
ReplyDeletecan any point in time it can be possible that ue may report two meas_id in one measurement report?
I mean that for meas_id = 1 say it sends everything PCI and meas results,can in the same report UE simply report meas_id with rsrp and rsrq results?
RSRP (-140 + 56) = - 84 dbm
ReplyDeleteRSRQ (-19.5 + 26) = -6.5 db

ReplyDeleteHI.. Thanks for the explanation.. When UE will send the measurement report apart from meas config provided by network? Periodically?
ReplyDeleteHI can you tell the difference between RRC reconfiguration and RRC restablishment. and any example scenario.
ReplyDeleteRRC CONFIGURAGATION WILL BE USE IN CONNECTED IF U ALREADY CONNECTED TO NETWORK....THEN YOU NEED MORE RESOURCE FOR DWONLAODING MOVIE, ETC THEN OUR RADIO RESOURCE WILL BE MODIFIED THEN HERE WILL USE RRC CONFIGURATION, AND IF RRRC CONFIGURATION FAIL DUE TO UE NOT HAVING VALID CONTEXT INFO , IF HANDOVER FAIL , MOBILITY EUTRAN COMMAND FAIL ....THEN AGAIN NEED TO RESTABLISH RRC CONNECTION THEN HERE WILL USE FOR RRC CONNECTION REESTABLISHMEN TPROCEDURE
DeleteHi
ReplyDeletecan u Please explain how UE decides periodicity of measurement reports it sends to eNB.
A2 report is triggered only when the serving cell become worst than the thresholdd value which is defined in the Sib1
ReplyDeleteHello,
ReplyDeleteGreetings!!!
We’re working on an internal testing to evaluate the signal strength and quality information across access technologies.
We obtain the Signal strength and quality from the UICC by issuing the PLI-NMR proactive command using Intra-frequency measurements to the UE.
Ideally, we should get the following data:
