Abstract
A method for transmitting uplink control information is provided The method includes receiving a Physical Downlink Shared Channel (PDSCH), determining Physical Uplink Control Channel (PUCCH) resources for feeding back Hybrid Automatic repeat Request Acknowledgement (HARQ-ACK) information of the PDSCH, and transmitting a HARQ-ACK of the PDSCH on the PUCCH resources according to at least one of HARQ-ACK timing information, the time domain duration of scheduling unit in a downlink bandwidth part and an uplink bandwidth part, or PUCCH resource indication information. The embodiments of the application further propose a corresponding user equipment and a corresponding computer storage medium.

A method performed by a terminal in a communication system, the method comprising:
- identifying one or more rows for physical downlink shared channel (PDSCH) time domain resource allocation (TDRA), wherein each of the one or more rows corresponds to a slot offset from a slot allocated for a physical downlink control channel (PDCCH) scheduling a PDSCH to a slot allocated for the PDSCH, a start symbol index of the PDSCH, and a length of the PDSCH;
- identifying whether a slot offset of a row among the one or more rows is 0;
- in case that the slot offset of the row is 0, identifying whether a start symbol index of a PDCCH monitoring occasion of the terminal is greater than 0;
- in case that the start symbol index of the PDCCH monitoring occasion is greater than 0, generating a row by replacing a start symbol index of the row, wherein the start symbol index of the generated row is determined by adding the start symbol index of the PDCCH monitoring occasion and the start symbol index of the row;
- adding the generated row to the one or more rows;
- and
- identifying one or more candidate PDSCH receptions for a semi-static hybrid automatic repeat request (HARQ)-acknowledgement (ACK) codebook, based on the one or more rows to which the generated row is added.
