12. A user equipment (UE) for wireless communication comprising:
a memory, and
at least one processor operatively coupled to the memory, the memory and the at least one processor configured to:
estimate channel characteristics of a secondary band based on measured characteristics of a channel in a primary band, the estimating occurring without measuring signals in the secondary band, the primary band detected in signals received from a non-serving cell of a first radio access technology (RAT), the non-serving cell comprising a first base station of the first RAT that is collocated with a second base station of a second RAT;
report, to a base station of a serving cell of the first RAT, the estimated channel characteristics of the secondary band; and
receive an indication of a secondary cell group, the secondary cell group determined based on the estimated channel characteristics of the secondary band.
