How to identify the CA capability from LTE Ue capability messages?

[eta004]

Hi Folks,

I am sharing below the supported CA combination messages in Ue capability Information.

How can we identify whether the Ue will support 2CA,3CA,4CA or 5 CA from these Ue capability messages.

Or Is there any other way to get this information

check this page , it show the detail message of CAband combinatiion

Hi

Yes I have referred this site earlier and I can show a sample from the site here below, but Can u help out in my sample data.
Below sample have a field "BandCombinationParameters-r10: 3 items" showing the number of CCs but in my case, I cant identify the combinations..Any idea ?

:

Following is the example for Band combination of a 3CC Carrier Aggregation.

the express may be some different according to what software you using. And your sample message is hard to read. is it possible upload raw data/ log for us to decode


this one is using nemo to decode the message

supportedBandCombination-r10 value 26
supportedBandCombination-r10 value 26 value 1
bandEUTRA-r10 : 20
bandParametersDL-r10
bandParametersDL-r10 value 1
ca-BandwidthClassDL-r10 : a
supportedMIMO-CapabilityDL-r10 : twoLayers
supportedBandCombination-r10 value 26 value 2
bandEUTRA-r10 : 3
bandParametersUL-r10
bandParametersUL-r10 value 1
ca-BandwidthClassUL-r10 : a
bandParametersDL-r10
bandParametersDL-r10 value 1
ca-BandwidthClassDL-r10 : a
supportedMIMO-CapabilityDL-r10 : twoLayers

I have attached the snap, I am using XCAL-MO for replay & XCAP for processing.

The picture is too small, i only find the message for single band capability

is it have more message ? if not . I guess the UE is non-CA UE. You can find the ue -category in message to check it.

Hi

I have sent you the drm file for processing and help me pls

Pls check private message for the drm file.
