A.1 SUPL 2.0 Positioning Methods and Positioning Protocols

38.3053GPPNG Radio Access Network (NG-RAN)Release 17Stage 2 functional specification of User Equipment (UE) positioning in NG-RANTS

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

The following table shows how the 3GPP positioning protocols are supported in SUPL 2.0.

Table A.1-1: SUPL support of positioning methods

NOTE 1: Excludes methods based on NR signals. NOTE 2: For LPP, NR CID is supported. NOTE 3: This includes TBS positioning based on PRS signals, which is only supported in LPP (LTE). NOTE 4: TBS positioning based on MBS signals. NOTE 5: Only barometric pressure sensor is supported.

NOTE: What is referred to in the SUPL specifications as "Enhanced Cell ID", is a UE-Assisted positioning mode, where the neighbouring cell measurements are carried at the SUPL layer (in the SUPL_POS_INIT for example). The ASN.1 container for this mode is defined as follows:
