1. Recommendations for Removal of AMPS in 3GPP2 Specifications July, 2010

2. 2 Overview Background –AMPS network shut down in 2008, allowing removal of special AMPS blocker requirements and harmonization of 3GPP and 3GPP2 specifications. 3GPP2 AMPS blocker protection/requirements –STD (Single Tone Desense) CW blockers at 900kHz (Band 0) or 1.25MHz offset –In-band IM CW blockers at 900kHz/1.7MHz (Band 0) or 1.25MHz/2.05MHz offset Modifications to C.S0011 (IS98) and C.S0033 (IS866) specifications –Details in following slides –BC3 and BC6 specs will not be modified

3. 3 Eliminate existing Single Tone Desense requirement (C.S0011 3.5.2, C.S0033 3.3.2) Replace with Narrow Band Blocking similar to 3GPP and apply to all bands (except BC3 and BC6) Single Tone Desense ParameterUnitTest-1 Î or dBm/1.23MHzREFSENS+3dB I blocking (CW)dBm-30 F uw (offset)MHz ±0.9 for BC0/3 ±1.25 for BC1/4 UE transmitted mean powerdBm +15 for BC1/3/4 +23 for other BCs ParameterUnitLevel Î or dBm/1.23MHzREFSENS+10dB I blocking (GMSK)dBm-45 F uw (offset)MHz ±1.10 for BC0 ±1.27 for other BC’s UE transmitted mean powerdBm20

4. 4 Modify existing intermodulation requirement (C.S0011 3.5.3, C.S0033 3.3.3) Replace with close-in and far-out IM requirements for all bands (except BC3 and BC6) Close-In Far-Out Intermodulation ParameterUnit Test-1/2 (BC0/1/3/4) Test-1/2 (BC 6 Only) Test-3/4 (BC0 only) Test-5/6 (BC0 only) Î or dBm/1.23MHzREFSENS+3dB REFSENS+14dBREFSENS+25dB I ouw1 (CW)dBm-43-48-32-21 I ouw2 (CW)dBm-43-48-32-21 F uw1 (offset)MHz ±0.9 for BC0/3 ±1.25 for BC1/4 ±2.5±0.9 F uw2 (offset)MHz ±1.7 for BC0/3 ±2.05 for BC1/4 ±4.9±1.7 ParameterUnitLevel Î or dBm/1.23MHzREFSENS+10dB I ouw1 (GMSK)dBm-46 I ouw2 (CW)dBm-46 F uw1 (offset)MHz1.27-1.27 F uw2 (offset)MHz2.64-2.64 UE transmitted mean powerdBm20 ParameterUnitLevel Î or dBm/1.23MHzREFSENS+3dB I ouw1 (CW)dBm-46 I ouw2 mean power (forward link CDMA)dBm-46 F uw1 (offset)MHz2.5-2.5 F uw2 (offset)MHz4.9-4.9 UE transmitted mean powerdBm20
