【正文】 he current TS already has requirements covering this case. For the case where 3rd order harmonic of band 20 falls into Band 7 uplink when both carriers are active, since the suppression of harmonic is relative large (. 80 dB) pared to the power difference between the two active carriers, the impact to high band transmitter can be ignored. Hence no further relaxation is needed.Table : 1 UL B20 + B7 harmonic productsBS DL carriersf1_lowf1_highf2_lowf2_highUL frequency (MHz)832862250025702ndoder harmonics frequency range (MHz)1664 to 17245000 to 51403rdoder harmonics frequency range (MHz)2496 to 25867500 to 7710 Coexistence studies for 2 UL/2 DLTable gives the intermodulation products for band 20 + band 7 CA with 2 ULs. For the 3tone IMD analysis the maximum transmission BW as defined in table is considered. Twotone and threetone third order IMD products can fall into the band 20 receiver. However, these products will not fall into the UE own receive block if the frequency range as defined with the channel bandwidths given in table are used for the more detailed IMD calculation.Considering bands in the same geographical area we observe that the UE distortion falls into the UE receive bands of Band 38 and 42. The magnitude of these possible IMD products have to be further studied with respect to spurious emission limits into these bands.Table : 2 ULs B20 + B7 IMD productsBS DL carriersf1_lowf1_highf2_lowf2_highDL frequency (MHz)83286225002570Twotone 2ndoder IMD products189。f2_low – f1_high189。189。f2_high – f1_low189。189。f2_low + f1_low189。189。f2_high + f1_high189。IMD frequency range (MHz)1638 to 17383332 to 3432Twotone 3rd order IMD products189。2*f1_low – f2_high189。189。2*f1_high – f2_low189。189。2*f2_low – f1_high189。189。2* f2_high – f1_low189。IMD frequency range (MHz)776 to 9064138 to 4308Threetone 3rd order IMD products(f1_low – max BW f2)(f1_high + max BW f2)(f2_low – max BW f1)(f2_high + max BW f1)IMD frequency range (MHz)812 to 8822490 to 2580 ΔTIB,c and ΔRIB (1 UL/ 2 DL)For the UE which supports CA_720 the ΔTIB,c is defined for applicable bands in table .Table : ΔTIB,cInterband CA ConfigurationEUTRA BandΔTIB,c [dB] CA_20A7A720NOTE: The values in the table reflect what can be achieved with the present state of the art technology.
