Power reduction mechanism verification According to the May 2017 TCBC Workshop, Demonstration of proper functioning of the detection and triggering mechanisms is required to support the corresponding RF exposure conditions. The verification is through a base station simulator is used to establish a conducted RF connection and monitor output power under different operating conditions related to the power reduction mechanisms. Detail of power reduction mechanisms referring to Operational Description 1. Power Verification Procedure The power verification was performed according to the following procedure: 1. A base station simulator was used to establish a conducted RF connection and the output power was monitored. The power measurements were confirmed to be within expected tolerances for all states before and after a power reduction mechanism was triggered. 2. Step 1 was repeated for all relevant modes and frequency bands for the mechanism being investigated. 3. Steps 1 and 2 were repeated for all individual power reduction mechanisms and combinations thereof. For the combination cases, one mechanism was switched to a 'triggered' state at a time; powers were confirmed to be within tolerances after each additional mechanism was activated. General Note: 1. This device uses different Exposure Condition Index (ECI) to configure different time averaged power levels based on certain exposure scenarios. ECI = 2 represents the case where the device is held to ear, ECI = 7 represents the case when hotspot mode is active, ECI = 4 represents the case is body and P-sensor is not active, ECI = 3 represents the case when Body-worn exposure condition and P-sensor on is active, and ECI = 6 represents the case when extremity exposure condition and P-sensor on is active. 2. Select the bands with the largest power reduction for power verification: a. Establish voice call and audio routed through the earpiece to monitor output power under head power states.  Tradition voice call for GSM/WCDMA, voice over IP CMRS operations for LTE/5G FR1  GSM1900 is set to GPRS 4TX slot, LTE Band 2/25 is set at ‘highest BW, 1RB, RB Offset = 0, QPSK’, WCDMA IV is set AMR 12.2Kbps, 5G FR1 n7 is set at highest BW, 1RB, RB offset = 1. b. Establish data connection monitor hotspot power state.  GSM1900 is set to GPRS 4TX slot, LTE Band 2/25 is set at ‘highest BW, 1RB, RB Offset = 0, QPSK’, WCDMA IV is set RMC 12.2Kbps, 5G FR1 n7 is set at highest BW, 1RB, RB offset = 1. c. Establish data connection monitor body worn power state.  GSM1900 is set to GPRS 4TX slot, LTE Band 2/25 is set at ‘highest BW, 1RB, RB Offset = 0, QPSK’, WCDMA IV is set RMC 12.2Kbps, 5G FR1 n7 is set at highest BW, 1RB, RB offset = 1.  Body Detect mechanism was performed for the in-hand and on a stationary object (placed on a table) d. Establish data connection monitor extremity power state.  GSM1900 is set to GPRS 4TX slot, LTE Band 2/25 is set at ‘highest BW, 1RB, RB Offset = 0, QPSK’, WCDMA IV is set RMC 12.2Kbps, 5G FR1 n7 is set at highest BW, 1RB, RB offset = 1.  Body Detect mechanism was performed for the in-hand and on a stationary object (placed on a table). 3. In this power validation purpose is to demonstrate of proper functioning of the detection and triggering mechanisms to support the corresponding RF exposure conditions. 4. Verification performed for one technology/Band to demonstrate that the power reduction applies for same technology/band and call origination. Appendix GReport No. : FA5D1519 Page:1/2 2.
