1. A user equipment (UE) comprising:
transmission circuitry configured to transmit, to a base station, capability information indicating multiple combinations (X,Y) for PDCCH monitoring, wherein each combination (X,Y) is associated with a respective maximum number of PDCCH candidates, a span is a number of consecutive OFDM symbols where the UE is configured to monitor PDCCH in a slot, and Y is a maximum number of the span which the UE can be configured with;
reception circuitry configured to receive configurations of search space sets to determine a set of spans, the search space sets including CSS set(s) and USS set(s); and
control circuitry configured to determine, from the multiple combinations (X,Y), one or more combinations (X,Y) wherein each value of X of the one or more combinations (X, Y) is equal to or less than values among separations of every two consecutive spans within the set of spans, and to determine, from the one or more combinations (X,Y), a combination (X,Y) with a largest maximum number of PDCCH candidates for the PDCCH monitoring, wherein
the reception circuitry is further configured to, for the PDCCH monitoring in the span,
monitor the PDCCH candidates of the CSS set(s) configured in the span, and
determine whether to monitor the PDCCH candidates of the USS set(s) configured in the span based on the maximum number of the PDCCH candidates of the combination (X,Y) per span and the number of the PDCCH candidates of the CSS set(s) configured in the span.
