3 GPP TSGRAN WG 4 Meeting 84 bis

3 GPP TSG-RAN WG 4 Meeting #84 bis Dubrovnik, Croatia, October 9 -13, 2017 Agenda: 9. 4. 3. 2 WF on power class in FR 2 Intel Corporation, Apple, Samsung, LGE, Huawei, Media. Tek, Xiaomi, vivo, OPPO, Motorola R 4 -1711609

Agreements (1) • A single power class is defined for handheld UEs operating in FR 2 in Rel-15 • The power class value is defined as the peak EIRP and is band dependent • Baseline definition: the peak EIRP requirement is defined as the minimum value with no tolerance; it is bounded by the range of values between 22 d. Bm and 30. 2 d. Bm according to reported results • Option to study: the peak EIRP requirement is defined as the nominal value with tolerance; companies are encouraged to provide the relevant analysis for the next meeting in case this option is preferred • For both Baseline and Option to Study, the derivation of peak EIRP value is itemized as shown in R 4 -1711406 as a baseline; additional terms are not precluded • The requirements on max allowed EIRP and upper limit TRP are defined as captured in R 4 -1710081 • Agreement on the peak EIRP is sufficient to complete to be reflected in the power class requirement by Dec 2017

Agreements (2) • Targeted spherical coverage of [20] d. Bm @ CDF 20 % will be verified with the following approaches in the next meeting • Approach 1 : simulated CDFs which model aspects captured in R 4 -1710708, R 4 -1711036 and below can be used. Other approaches are not precluded Parameter Value EIRP radiation pattern coordinate system Spherical EIRP radiation pattern elevation & azimuth angle step size 1 deg Simulated pattern considers the presence of a full screen display panel (with LCD or OLED) and battery Yes Method of CDF generation from EIRP radiation pattern Test points with equal area on the spherical surface [1] Simulated pattern considers the device case material Simulated pattern considers the gap between antenna & housing • Approach 2: measured CDFs from prototype devices can also be used; the spherical coverage requirement shall defined as a minimum requirement in Rel-15 • If the above target cannot be verified with the approaches above by RAN 4#85, [20] d. Bm @ CDF 20 % should be specified with square brackets for NSA completion and RAN 4 will continue to study the appropriate requirement until June 2018.
