Cell scanning, 5GNR_ML1_MEAS_DATABASE_UPDATE ssb_ref_timing #122

Description

@gsr933

Not really an scat issue, but the top 32 bits of ssb_ref_timing is a 30.72 MHz counter that wraps around at 10.24 seconds. Note that this is the SFN wraparound interval but is not synchronized to SFN = 0. I find this quite useful for trilaterating 5G cells. So,

  • Does anyone know what the bottom 32 bits are?
  • Is there a way to trigger an 5G NR ML1 measurement? As a workaround on a Quectel modem, setting a PCI lock for a non-existent cell would cause the modem to continuously scan and send ML1 measurements, except for cell barred 5G NSA cells which are ignored most of the time.
