1. A method, comprising:
receiving configuration information on hybrid automatic repeat request-acknowledge (HARQ-ACK) feedback for physical downlink shared channel (PDSCH), wherein the configuration information at least indicates a plurality of CORESETPoolIndex values and a separate feedback mode for HARQ-ACK feedback excluding that for semi-persistent scheduling (SPS) PDSCH reception associated with different CORESETPoolIndex values, each CORESETPoolIndex value being associated with at least one physical uplink control channel (PUCCH) resource; and
transmitting a plurality of HARQ-ACK feedback for SPS PDSCH reception associated with at least one CORESETPoolIndex value in a time interval using a separate feedback scheme or a joint feedback scheme, wherein:
while using the separate feedback scheme, for each CORESETPoolIndex value, all HARQ-ACK feedback for SPS PDSCH reception associated with the CORESETPoolIndex value is transmitted in a corresponding associated PUCCH resource; and
while using the joint feedback scheme, all HARQ-ACK feedback for SPS PDSCH reception associated with all CORESETPoolIndex values is transmitted in a PUCCH resource associated with a single CORESETPoolIndex value of the plurality of CORESETPoolIndex values.
