wer (TRP), total isotropic sensitivity (TIS), and LTE MIMO/SISO throughputs, and these tests do not constitute a 3GPP pass/fail criteria: they are, for example, part of the PTCRB conformance tests based on the CTIA OTA test plans, giv- ing operators a useful insight into UE performance [8]. Translating all core requirements into the OTA test cases has created a lot of discussion and test methodology challenges, SO much SO that many test cases are not yet completely finalized at the time of writing (cf. Section 12.4.6). For the transmitter chain, two key performance indicators are defined in addition to TRP: The peak effective isotropic radiated power (EIRP) is a measure of the UE maximum transmitted power with the UE Tx beam locked in the beam peak direction. The UE 12.4 5G Standalone Performance Aspects in mmWave Frequency Range 2 beam peak direction is found with a 3D EIRP scan separately for each polarization, for which three measurements techniques are considered: Direct Far Field (DFF), Indi- rect Far Field (IFF), and Near-Field to Far-Field transform (NFTF). The average UE Tx power is measured with a spectrum analyzer, and is then converted into the EIRP using several correcting OTA factors, such as path loss due to distance, measurement antenna factor, and SO on. The EIRP spherical coverage (SC) is key to assessing the UE ability to steer its numer- ous beam patterns and the performance of UE beam management algorithms. The uplink SC is evaluated by the cumulative distribution function (CDF) of the EIRP, where CDF = 100% corresponds to the peak EIRP. For the FR2 PC3 UE, the uplink SC has been agreed upon after numerous contributions at CDF = 50% as a compromise between the UE model using only one antenna panel and the UE model using two pan- els [10]. Table 12.6 below summarizes the PC3 transmit power KPIs and shows that at 28 GHz, the difference between SC and the peak EIRP is 10.9 dB. An ideal UE with perfect isotropic radiation pattern would exhibit a 0 dB difference; on the contrary, a UE with a very l
