Are Scell activation conditions same in LTE and NR?

Hi Experts.

Are Scell activation conditions same in LTE and NR?

What are the conditions other than timebound DL and UL traffic RLC buffer check /bsr based SCC activation-and deactivation?

Can A2rsrp threshold for CA be used instead of A5rsrp thres1 so that A5 rsrpthres2 can be used without A5rsrpthesh1?
