Note 1: Parameters “Expected RSTD” and “Expected RSTD uncertainty for all neighbour cells” are not settable parameters. These are parameters signalled in LPP only. For the values to be used in LPP see Table 9.4.14.4.3-5 and TS 37.571-5 [20], clause 7.2.5. Note 2: Parameters “PRS Transmission Bandwidth”, “PRS configuration index”, “Number of consecutive downlink positioning subframes”, “Physical cell ID PCI”, “CP length”, and “PRS muting info” are settable parameters and also parameters signalled in LPP. The values to be used for “Physical cell ID PCI” are as follows: Cell 1: 0, Cell 2: 6, Cell 3: 12. For all the values to be used in LPP see Table 9.4.14.4.3-5 and TS 37.571-5 [20], clause 7.2.5. Note 3: The parameter “Radio frame receive time offset between the cells at the UE antenna connector” is not a settable parameter but is used to set the “true RSTD” values in step 6 of clause 9.4.14.4.1. Note 4: If the PRS transmission bandwidth is larger than the UE RF bandwidth, the UE is measuring RSTD within its RF bandwidth. |
