6.5 Transmit signal quality

36.521-13GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Part 1: Conformance testingRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification

Editor’s note: The test cases for transmit signal quality: frequency error, EVM, carrier leakage, IBE, EVM equalizer spectrum flatness are complete, except the following aspect is not determined:

– Reference signal EVM and PRACH EVM minimum requirements from the core specification are still in brackets.

In this clause a multitude of results are derived, all using one common algorithm returning these results: Global In-Channels TX-Test (Annex E). Each sub clause of this clause contains a procedure and test requirements described for a specific measurement. If all relevant test parameters in different sub clauses are the same, then the results, returned by the Global In-Channel TX-Test, may be used across the applicable sub clauses.

For UE category M1, carrier centre frequency can be either at the centre of channel bandwidth or the 6RB narrowband assigned for transmission. TE shall measure frequency error, EVM, carrier leakage, In-band emissions and EVM equalizer spectrum flatness using Global In-Channels TX-Test (Annex E) according to the UE’s declaration on the position of carrier centre frequency.
