[srsran-users] About SRSUE SA mode

Hi，all
I'm trying to run SRS UE in NR SA Mode. According to doc page'5G SA srsUE'，there is  a few limitaions as follow

Limited to 15 kHz Sub-Carrier Spacing (SCS), which means only FDD bands can be used.
Limited to 10 MHz Bandwidth (BW)
by reviewing the code , the listed limitations are limited by 

 ("rat.nr.bands",        bpo::value<string>(&args->stack.rrc_nr.supported_bands_nr_str)->default_value("3"),   "Supported NR bands")
    ("rat.nr.nof_carriers", bpo::value<uint32_t>(&args->phy.nof_nr_carriers)->default_value(0),                   "Number of NR carriers")
    ("rat.nr.max_nof_prb",  bpo::value<uint32_t>(&args->phy.nr_max_nof_prb)->default_value(52),                   "Maximum NR carrier bandwidth in PRB")
    ("rat.nr.dl_nr_arfcn",  bpo::value<uint32_t>(&args->stack.rrc_nr.dl_nr_arfcn)->default_value(368500),         "DL ARFCN of NR cell")
    ("rat.nr.ssb_nr_arfcn", bpo::value<uint32_t>(&args->stack.rrc_nr.ssb_nr_arfcn)->default_value(368410),        "SSB ARFCN of NR cell")
    ("rat.nr.nof_prb",      bpo::value<uint32_t>(&args->stack.rrc_nr.nof_prb)->default_value(52),                 "Actual NR carrier bandwidth in PRB")
    ("rat.nr.scs",          bpo::value<string>(&scs_khz)->default_value("15"),                                    "PDSCH subcarrier spacing in kHz")
    ("rat.nr.ssb_scs",      bpo::value<string>(&ssb_scs_khz)->default_value("15"),                                "SSB subcarrier spacing in kHz")

did  anyone  try some different configurations like 

 ("rat.nr.bands",        bpo::value<string>(&args->stack.rrc_nr.supported_bands_nr_str)->default_value("78"),   "Supported NR bands")
    ("rat.nr.nof_carriers", bpo::value<uint32_t>(&args->phy.nof_nr_carriers)->default_value(0),                   "Number of NR carriers")
    ("rat.nr.max_nof_prb",  bpo::value<uint32_t>(&args->phy.nr_max_nof_prb)->default_value(51),                   "Maximum NR carrier bandwidth in PRB")
    ("rat.nr.dl_nr_arfcn",  bpo::value<uint32_t>(&args->stack.rrc_nr.dl_nr_arfcn)->default_value(627348),         "DL ARFCN of NR cell")
    ("rat.nr.ssb_nr_arfcn", bpo::value<uint32_t>(&args->stack.rrc_nr.ssb_nr_arfcn)->default_value(627264),        "SSB ARFCN of NR cell")
    ("rat.nr.nof_prb",      bpo::value<uint32_t>(&args->stack.rrc_nr.nof_prb)->default_value(52),                 "Actual NR carrier bandwidth in PRB")
    ("rat.nr.scs",          bpo::value<string>(&scs_khz)->default_value("30"),                                    "PDSCH subcarrier spacing in kHz")
    ("rat.nr.ssb_scs",      bpo::value<string>(&ssb_scs_khz)->default_value("30"),                                "SSB subcarrier spacing in kHz")

thx !
