G.1 Receiver RF Requirements Testing

36.1123GPPLocation Measurement Unit (LMU) conformance specificationNetwork based positioning systems in Evolved Universal Terrestrial Radio Access Network (E-UTRAN)Release 17TS

The measurement set-ups in this clause are for the LMU RF requirements for class 2 and class 3 LMUs specified in Section 5 of TS 36.111. The test ports and the RF requirements applicability are as specified in Section 5.1 of TS 36.111. If any external apparatus, e.g., a RX amplifier, a filter or the combination of such devices is used, LMU RF requirements apply and are tested at the far end antenna connector (port B); otherwise, the requirements apply at port A. No additional testing is necessary for class 1 LMUs, in addition to base station conformance tests specified in TS 36.141.

Degradation of the base station DL performance and base station UL performance may occur when LMU class 2 is co-sited with the base station; therefore the impact on BS shall also be tested in conjunction with the LMU Receiver RF conformance tests of this specification.
