1. A method, comprising:
determining a monitoring span for monitoring a physical downlink control channel (PDCCH) within a slot, the monitoring span having a start symbol and a duration that spans one or more symbols within the slot;
determining at least one of a maximum number of blind decoding (BD) attempts or a maximum number of control channel elements (CCEs) for channel estimation based on the monitoring span;
monitoring the PDCCH within the monitoring span up to the at least one of the maximum number of BD attempts or the maximum number of CCEs; and
adjusting the monitoring span in response to an indication of a change in a number of monitoring occasions within the slot.
