Claim of US Patent No. 10,893,536
1. A terminal for transmitting an uplink control channel in a wireless communication system, the terminal comprising:at least one radio frequency (RF) transceiver;
at least one processor; and
at least one memory that is operably connectable to the at least one processor and that has stored thereon at least one program which, when executed, causes the at least one processor to perform operations comprising:
receiving a first physical downlink shared channel (PDSCH) based on a first transmission time interval (TTI) length;
receiving a second PDSCH based on a second TTI length different from the first TTI length; and
transmitting a first hybrid automatic repeat request acknowledgment (HARQ-ACK) feedback for the first PDSCH and a second HARQ-ACK feedback for the second PDSCH,
wherein transmitting the first HARQ-ACK feedback for the first PDSCH and the second HARQ-ACK feedback for the second PDSCH comprises:
based on transmission of the first HARQ-ACK feedback overlapping in time with transmission of the second HARQ-ACK feedback, transmitting the first HARQ-ACK feedback and the second HARQ-ACK feedback on a physical uplink control channel (PUCCH) with the first TTI length or the second TTI length, whichever is the shorter TTI length.
at least one processor; and
at least one memory that is operably connectable to the at least one processor and that has stored thereon at least one program which, when executed, causes the at least one processor to perform operations comprising:
receiving a first physical downlink shared channel (PDSCH) based on a first transmission time interval (TTI) length;
receiving a second PDSCH based on a second TTI length different from the first TTI length; and
transmitting a first hybrid automatic repeat request acknowledgment (HARQ-ACK) feedback for the first PDSCH and a second HARQ-ACK feedback for the second PDSCH,
wherein transmitting the first HARQ-ACK feedback for the first PDSCH and the second HARQ-ACK feedback for the second PDSCH comprises:
based on transmission of the first HARQ-ACK feedback overlapping in time with transmission of the second HARQ-ACK feedback, transmitting the first HARQ-ACK feedback and the second HARQ-ACK feedback on a physical uplink control channel (PUCCH) with the first TTI length or the second TTI length, whichever is the shorter TTI length.
