1. A method performed by a network node for determining physical downlink shared channel (PDSCH) hybrid automatic repeat request-acknowledgement (HARQ-ACK) processing timing, comprising:
determining that a user equipment (UE) is configured for single downlink control information (single-DCI) multiple transmission and reception point (multi-TRP) PDSCH operation;
determining a first PDSCH and a second PDSCH within a slot, wherein the first PDSCH and the second PDSCH are used in the single-DCI multi-TRP PDSCH operation; and
determining an overall minimum HARQ-ACK processing timing for both the first PDSCH and the second PDSCH using one or more symbols of the first PDSCH or one or more symbols of both the first PDSCH and the second PDSCH; and
assigning the UE with HARQ-ACK timing K1 and a PUCCH resource to be used for a HARQ-ACK based on the overall minimum HARQ-ACK processing timing.
