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

    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

    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.

    • nonCriticalExtension
      ue-Category-v1020: 6
      rf-Parameters-v1020
      supportedBandCombination-r10: 15 items
      Item 0
      BandCombinationParameters-r10: 3 items
      Item 0
      BandParameters-r10
      bandEUTRA-r10: 1
      bandParametersUL-r10: 1 item

    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

    =============================================

    this one is using actix

    - . . . . . .supportedBandCombination-r10 [ 26 ] [ 0 ]
    - . . . . . . .bandEUTRA-r10: 8
    - . . . . . . .bandParametersUL-r10 [ 0 ]
    - . . . . . . . .ca-BandwidthClassUL-r10: 0
    - . . . . . . .bandParametersDL-r10 [ 0 ]
    - . . . . . . . .ca-BandwidthClassDL-r10: 0
    - . . . . . . . .supportedMIMO-CapabilityDL-r10: 0
    - . . . . . .supportedBandCombination-r10 [ 1 ]
    - . . . . . . .bandEUTRA-r10: 3
    - . . . . . . .bandParametersDL-r10 [ 0 ]
    - . . . . . . . .ca-BandwidthClassDL-r10: 0
    - . . . . . . . .supportedMIMO-CapabilityDL-r10: 0

    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.
