High power UE (power class 1.5 or 2) for NR Inter-band Carrier Aggregation (CA)/Dual Connectivity (DC) with/without Supplementary Uplink (SUL) with high power on TDD band(s)
The present document is one of four technical reports for High power UE (power class 1.5 or 2) for NR Inter-band Carrier Aggregation (CA)/Dual Connectivity (DC) with/without Supplementary Uplink (SUL) with high power on TDD band(s) under Rel-19 timeframe. The objective is to gather the relevant background information and studies in order to complete the band-combination specific requirements for the newly requested band combinations for power class 2 and power class 1.5 UE. Table 1-1 lists the band combinations covered by this TR with three power class cases for uplink.

High power UE (power class 1.5 or 2) for NR Inter-band Carrier Aggregation (CA)/Dual connectivity (DC) with/without Supplementary uplink (SUL) with high power on TDD band(s)
Note: Including PC3 FDD/TDD+ PC3 TDD case
PC2 inter-band CA/DC:
1UL(TDD): PC2 on TDD band
2UL (TDD+TDD): PC3 or PC2 on TDD band
2UL (FDD+TDD): PC3 on FDD band, PC3 or PC2 on TDD band
PC1.5 inter-band CA/DC:
1UL(TDD): PC 1.5 on TDD band
2UL (TDD+TDD): PC3, PC2 or PC1.5 on TDD band
2UL (FDD+TDD): PC3 on FDD band, PC1.5 on TDD band
PC2 SUL band combinations with or without CA:
SUL: PC3 or PC2 on SUL band
NUL(TDD): PC2 on TDD band
PC1.5 SUL band combinations with or without CA:
SUL: PC3 or PC2 on SUL band
NUL(TDD): PC1.5 on TDD band
NUL = Normal Uplink in contrast to SUL.
