CORESET duration?

While I was reading 3gpp spec 38.213 for studying Wake Up Signal

In subclasue 10.3 ‘PDCCH monitoring indication and dormancy/non-dormancy behaviour for SCells’

I saw sentence
'for each search space set, the PDCCH monitoring occasions are the ones in the first T_“s” slots indicated by duration, or T_“s” =1 slot if duration is not provided, starting from the first slot of the first T_“s” slots and ending prior to the start of drx-onDurationTimer. ’

In this sentence, does the word ‘duration’ means the duration in CORESET?
Please explain the meaning of this word ‘duration’ and how this sentence works for WUS.

CORESET duration

It means seach space duration which is in the unit of slots
Coreset duration is in the unit of symbols
