FCC ID: A3LSMS948U RF EXPOSURE PART 1 TEST REPORT Approved by: Technical Manager DUT Type: Portable Handset APPENDIX E: Page 1 of 14 A P P E N D I X E : M U L T I-T X A N D A N T E N N A S A R C O N S I D E R A T I O N S E.1 Introduction The following procedures adopted from FCC KDB Publication 447498 D04v01 are applicable to devices with built- in unlicensed transmitters such as 802.11 and Bluetooth devices which may simultaneously transmit with the licensed transmitter E.2 Simultaneous Transmission Procedures This device contains transmitters that may operate simultaneously. Therefore, simultaneous transmission analysis is required. Per FCC KDB Publication 447498 D04v01 and IEEE 1528-2013 Section 6.3.4.1.2, simultaneous transmission SAR test exclusion may be applied when the sum of the 1g SAR for all the simultaneous transmitting antennas in a specific a physical test configuration is ≤1.6 W/kg (or 4 W/kg for 10g). The different test positions in an exposure condition may be considered collectively to determine SAR test exclusion according to the sum of 1g or 10g SAR. Alternatively, simultaneous transmission SAR test exclusion may be evaluated using Total Exposure Ratio (TER). The different test positions in an exposure condition may be considered collectively to determine SAR test exclusion according to the TER. Per FCC KDB Publication 941225 D06v02r01, the devices edges with antennas more than 2.5 cm from edge are not required to be evaluated for SAR (“-“). This device is enabled with Qualcomm® Smart Transmit Plus with pre-defined antenna groups (AG0 and AG1) and 1 mmW module group (MG). Sub6 and mmW antennas cannot be decoupled from each other due to lack of regulatory criteria. This device operates using GEN2_SUB6 (Sub6-favor mode) which assumes all mmW modules (MG) are collocated with each sub6 AG0 and AG1 in this device. The Simultaneous transmission analysis is performed per antenna groups. Below analysis demonstrates the mutually exclusive operation of AG0 and AG1, and the compliance between each antenna group with non-Smart Transmit Radios. For this model, WWAN/WLAN/BT/NTN/mmWave Radios are managed under Smart Transmit. Non-Smart Transmit Radios include NFC/UWB. When operating in the same antenna group, the compliance under dynamic transmission condition, including all supported simultaneous transmission scenarios, should be assessed and demonstrated in the Part 2 Report during algorithm validation. Therefore, no further simultaneous analysis is needed within an antenna group. When all WWAN/WLAN/BT/mmWave Radios are managed under Smart Transmit, TER for WWAN/WLAN/BT/mmWave is covered in Part 2 testing. Only external radios outside of WWAN/WLAN/BT/mmWave (UWB, NFC) require TER analysis with WWAN/WLAN/BT/mmWave during simultaneous transmissions. NTN transmission is also managed under Smart transmit; however, simultaneous analysis with modes outside of NTN are not evaluated because NTN is the only available radio in satellite mode. E.3 Sub6 Antenna Groups The 2nd generation of Smart Transmit (GEN2) operates based on pre-defined antenna groups (AG). Sub6/WLAN/BT Tx Antennas and/or mmW module groups (MG) in the device are grouped based on spatial variation of RF exposure distributions, where the RF exposure of one AG is mutually exclusive from other AG. This is accomplished by demonstrating either of below conditions for all exposure scenarios: a) Sum of SAR of one antenna from each of the sub6 AGs and the RF exposure from radios outside Smart Transmit is less than regulatory limits. This condition must be demonstrated for all antenna combinations of sub6 AGs. (or) FCC ID: A3LSMS948U RF EXPOSURE PART 1 TEST REPORT Approved by: Technical Manager DUT Type: Portable Handset APPENDIX E: Page 2 of 14 b) Every antenna from each sub6 AG meets SPLSR criteria (Section 4.3.2(c) in FCC KDB 447498 D04) with every antenna from another sub6 AG. This criteria must be demonstrated for all antenna combinations for each pair of AGs. This device supports two AGs: AG0 and AG1, with AG0 having 4 antennas (A, B, C, D) and AG1 having 5 antennas (E, F, G, H, I) and MG having 1 antenna (L)The conditions are verified through the following criteria: i) In Sub6-favor mode: All mmW antennas are assumed to collocate with each sub6 antenna group (AG). Also, since all mmW MGs are controlled by Smart Transmit, maximum mmW exposure is given by maximum out of all mmW modules: max.norm.exp.mmW = max.norm.exp.MG ii) Sum of SAR: Demonstrate that the sum of 푚푎푥.푛표푟푚.푒푥푝.퐴퐺0 and 푚푎푥.푛표푟푚.푒푥푝.퐴퐺1 and the reported normalized SAR values from radios outside Smart Transmit (denoted as reported.norm.exp.ER) should be less than the regulatory limit for each supported DSI following the below procedure: 1. Obtain the worst-case adjusted SAR for each antenna group, i.e., maximum reported SAR at EFS P limit +unc (or max of {P max +unc, EFS P limit } when EFS P limit > P max ) out of all supported technologies, frequency bands and antennas in AG0 and AG1, then normalized to the regulatory limit to get the maximum normalized SAR for each antenna group, denoted as: 푚푎푥.푛표푟푚.푒푥푝.퐴퐺0 and 푚푎푥.푛표푟푚.푒푥푝.퐴퐺1 2. For external radios outside of Smart Transmit (NFC/UWB): Obtain the worst-case RF exposure for each external radio normalized to regulatory limit to get the normalized SAR for each external radio, denoted as: reported.푛표푟푚.푒푥푝.NFC and reported.푛표푟푚.푒푥푝.UWB 3. Demonstrate that the sum of these RF exposures meets: {ma푥.푛표푟푚.푒푥푝.퐴퐺0 +푚푎푥.푛표푟푚.푒푥푝.퐴퐺1+ reported.푛표푟푚.푒푥푝.NFC + reported.푛표푟푚.푒푥푝.UWB } ≤ 1. iii) SPLSR or composite exposure distribution criteria: when TER sum of an antenna pair is over the limit for a DSI/exposure position, SPLSR or composite exposure distribution can be done to demonstrate simultaneous transmission compliance. 1. SPLSR analysis for sub6 antenna pairs: For each antenna, obtain the highest adjusted SAR at EFS P limit +unc (or max of {P max +unc, EFS P limit } when EFS P limit > P max ) out of all supported te…

FCC ID: A3LSMS948U RF EXPOSURE PART 1 TEST REPORT Approved by: Technical Manager DUT Type: Portable Handset APPENDIX G: Page 1 of 1 A P P E N D I X G : S A R S Y S T E M V A L I D A T I O N Per FCC KDB Publication 865664 D02v01r02, SAR system validation status should be documented to confirm measurement accuracy. The SAR systems (including SAR probes, system components and software versions) used for this device were validated against its performance specifications prior to the SAR measurements. Reference dipoles were used with the required tissue- equivalent media for system validation, according to the procedures outlined in FCC KDB Publication 865664 D01v01r04 and IEEE 1528-2013. Since SAR probe calibrations are frequency dependent, each probe calibration point was validated at a frequency within the valid frequency range of the probe calibration point, using the system that normally operates with the probe for routine SAR measurements and according to the required tissue-equiv…
