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 9.4.7.1.4.3-5 and TS 37.571-5 [20], clause 7.2.5. Note 2: Parameters “PRS Transmission Bandwidth”, “PRS configuration index”, “Number of consecutive positioning downlink subframes”, “prs-MutingInfo”, “Cell ID” and “CP length” are settable parameters and also parameters signalled in LPP. The values to be used for “Cell ID” are as follows: Cell 1: 0, Cell 2: 6. For all the values to be used in LPP see Table 9.4.7.1.4.3-4 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 9.4.7.1.4.1. Note 4: If the PRS transmission bandwidth is larger than the UE RF bandwidth, the UE is measuring RSTD within its RF bandwidth. Note 5: The parameter “” is not a settable parameter but is used to set the LPP “time” value in Table 9.4.7.1.4.3-3. The value of the LPP time IE is set to + T ms, where T = 150 ms, giving a value of 15510 ms. This is rounded up to the next allowed LPP value of 16 seconds. |

Note 1: OCNG shall be used such that both cells are fully allocated and a constant total transmitted power spectral density is achieved for all OFDM symbols (other than those in the PRS subframes). Note 2: Interference from other cells and noise sources not specified in the test is assumed to be constant over subcarriers and time and shall be modelled as AWGN of appropriate power for to be fulfilled. Note 3: , PRS , Io, RSRP and PRP levels have been derived from other parameters for information purposes. They are not settable parameters themselves. Io values are derived in the case that there is no PBCH, PSS or SSS in the OFDM symbols carrying PRS Note 4: Test2 is not used for test 9.4.9.1 |
