The ones might be wrong are:

    { &hf_nr_rrc_scs_30kHz_10,
      { "scs-30kHz", "nr-rrc.scs_30kHz",

  { NULL, 0, 0, NULL }
};

The rest of the hf_nr_rrc_scs_30kHz* has FT_UINT32, BASE_DEC and VALS(...) which I think all are OK.

So perhaps these would be the additional lines in the cnf?

Sure, but does it have different field types?

The renaming was done to fix "the same filter name used for different ft types". Maybe this one don't have a duplicate? If it has a duplicate than it's a bug. If not it could still be renamed for consistency.

Hi community,

I have a question related to the nr-rrc protocol channelBWs scs-30kHz field name.

As an example, in a UE Capability Information message for NR bands we have channel BWs DL/UL fr1 like this:

channelBWs-DL: fr1 (0)
    fr1
        scs-15kHz: 0000 [bit length 10, 6 LSB pad bits, 0000 0000  00.. .... decimal value 0]
        scs-30kHz: 77c0 [bit length 10, 6 LSB pad bits, 0111 0111  11.. .... decimal value 479]
        scs-60kHz: 0000 [bit length 10, 6 LSB pad bits, 0000 0000  00.. .... decimal value 0]

The respective field names are:

nr-rrc.bandNR.channelBWs_DL.fr1.scs_15kHz

nr-rrc.scs_30kHz    <---- why?

nr-rrc.bandNR.channelBWs_DL.fr1.scs_60kHz

These related to the asn1 .cnf file settings (30kHz is missing):

#.FIELD_RENAME

BandNR/channelBWs-DL/fr1/scs-15kHz         bandNR_channelBWs-DL_fr1_scs-15kHz
BandNR/channelBWs-UL/fr1/scs-15kHz         bandNR_channelBWs-UL_fr1_scs-15kHz

BandNR/channelBWs-DL/fr1/scs-60kHz         bandNR_channelBWs-DL_fr1_scs-60kHz
BandNR/channelBWs-UL/fr1/scs-60kHz         bandNR_channelBWs-UL_fr1_scs-60kHz

#.FIELD_ATTR

BandNR/channelBWs-DL/fr1/scs-15kHz         ABBREV=bandNR.channelBWs_DL.fr1.scs_15kHz
BandNR/channelBWs-UL/fr1/scs-15kHz         ABBREV=bandNR.channelBWs_UL.fr1.scs_15kHz

BandNR/channelBWs-DL/fr1/scs-60kHz         ABBREV=bandNR.channelBWs_DL.fr1.scs_60kHz
BandNR/channelBWs-UL/fr1/scs-60kHz         ABBREV=bandNR.channelBWs_UL.fr1.scs_60kHz

header fields in the .c file:

    { &hf_nr_rrc_bandNR_channelBWs_DL_fr1_scs_15kHz,
      { "scs-15kHz", "nr-rrc.bandNR.channelBWs_DL.fr1.scs_15kHz",
        FT_BYTES, BASE_NONE, NULL, 0,
        "BIT_STRING_SIZE_10", HFILL }},
    { &hf_nr_rrc_scs_30kHz_09,
      { "scs-30kHz", "nr-rrc.scs_30kHz",
        FT_BYTES, BASE_NONE, NULL, 0,
        "BIT_STRING_SIZE_10", HFILL }},
    { &hf_nr_rrc_bandNR_channelBWs_DL_fr1_scs_60kHz,
      { "scs-60kHz", "nr-rrc.bandNR.channelBWs_DL.fr1.scs_60kHz",
        FT_BYTES, BASE_NONE, NULL, 0,
        "BIT_STRING_SIZE_10", HFILL }},

Is this deliberate or a minor bug?

Shouldn't there be the same logic for scs-30kHz too?

Thank you.

Regards,

Tamas
