High power UE for NR inter-band Carrier Aggregation with 2 bands downlink and x bands uplink (x =1,2)
The present document is a technical report for high power UE (power class 2) for NR inter-band Carrier Aggregation with 2 bands downlink and 2 bands uplink under Rel-17 time frame. The purpose is to gather the relevant background information and studies in order to address power class 2 NR inter-band CA for 2 bands DL with 2 bands UL in Table 1-1.
