4. General notes The categorization of band combinations is up to RAN4
For the previous slides
The categorization of band combinations is up to RAN4
RAN4 is to define a rule for categorization (of band combinations including channel assignments) in order to apply them
A possible rule could be based on presence of resulting IMD[2]…[7] (including harmonics as long as the cause includes simultaneous Tx) falling in Rx with the given channel assignment
Applies to a triplet of CCs
1 LTE PCell UL + 1 NR PSCell UL + 1 NR PSCell DL, or
1 LTE PCell UL + 1 NR PSCell UL + 1 LTE PCell DL
