Same as in clause 9.4.4.2.4.3.

9.4.6.2.5 Test requirement

The primary level settings including test tolerances for the test are defined in clause 9.4.6.1.5.

For Test 1, the response time is defined in clause 9.4.6.1.5.

For Test 2, the response time including test tolerance is 11.3 s. The response time is equal to the LPP time IE value plus the test tolerance. The LPP time IE value is derived from the RSTD reporting delay plus ΔT, where ΔT = Nrepx TTIDCCH = Nrepx 75 ms, giving a value of 10390 ms. This is rounded up to the next allowed LPP value of 11 seconds. The RSTD measurement reporting delay in the test is derived from the following expression , where =40 and =16 are the parameters specified in clause 9.4.1.1.3, Table 9.4.1.1.3‑1 and Note 4 of Table 9.4.6.2.4.1-1. This gives the total RSTD reporting delay of 10240 ms for the 15 neighbour cells including Cell 2 and Cell 3 with respect to the reference cell, Cell 1.

The test tolerances are defined in clauses C.1.3 and C4.

For the overall test to pass, the ratio of successful reported values in each sub-test shall be more than 90% with a confidence level of 95%.
