1 Scope p. 11
The present document specifies the measurement procedures for the conformance test of the NR User Equipment (UE) supporting satellite access operation that contains RF and Performance requirements.

4 General p. 13
4.1 Relationship between minimum requirements and test requirements p. 13
TS 38.101-5 is a Single-RAT specification for satellite NR UE, covering RF characteristics and minimum performance requirements. Conformance to the TS 38.101-5 is demonstrated by fulfilling the test requirements specified in the present document.
The Minimum Requirements given in TS 38.101-5 makes no allowance for measurement uncertainty (MU). The present document defines test tolerances (TT). These test tolerances are individually calculated for each test. The test tolerances are used to relax the minimum requirements in this specification to create test requirements. For some requirements, including regulatory requirements, the test tolerance is set to zero.
The measurement results returned by the test system are compared - without any modification - against the test requirements as defined by the various levels of "shared risk" principle as described below.
-
Core specification value is not relaxed by any relaxation value (TT=0). For each single measurement, the probability of a borderline good UE being judged as FAIL equals the probability of a borderline bad UE being judged as PASS.
- Test tolerances equal to 0 (TT=0) are considered in this specification.
-
Core specification value is relaxed by a relaxation value (TT>0). For each single measurement, the probability of a borderline bad UE being judged as PASS is greater than the probability of a borderline good UE being judged as FAIL.
- Test tolerances lower than measurement uncertainty and greater than 0 (0 < TT < MU) are considered in this specification.
- Test tolerances up to measurement uncertainty (TT = MU) are considered in this specification which is also known as "Never fail a good DUT" principle.
-
Core specification value is tightened by a stringent value (TT<0). For each single measurement, the probability of a borderline good UE being judged as FAIL is greater than the probability of a borderline bad UE being judged as PASS.
- Test tolerances lower than 0 (TT<0) are not considered in this specification..
4.2 Applicability of minimum requirements p. 14
The applicability of each requirement is described under clauses 6.1, 7.1, 8.1 of TS 38.101-5.
The conducted minimum requirements specified in the present document shall be met in all applicable scenarios for FR1.
The spurious emissions power requirements are for the long-term average of the power. For the purpose of reducing measurement uncertainty, it is acceptable to average the measured power over a period of time sufficient to reduce the uncertainty due to the statistical nature of the signal.
4.3 Specification suffix information p. 14
Specification suffix information is not defined for the time being in Release 17.
4.4 Relationship with core specifications p. 14
TS 38.101-5 specifies the minimum RF and performance requirements for NR User Equipment (UE) operating in a Non-Terrestrial Network. TS 38.108 specifies the minimum RF and performance requirements of Satellite Access Node (SAN).
