Method and user equipment of transmitting uplink signal in wireless communication system, and method and base station of receiving uplink signal in wireless communication system

A method of receiving an uplink (UL) signal by a base station (BS) from a user equipment (UE) configured for simultaneous physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH) transmission in a wireless communication system, the method comprising:

• transmitting, to the UE through a physical downlink control (PDCCH), downlink control information (DCI) regarding subslot-based semi-persistent scheduling (SPS) PUSCH, wherein the DCI includes a demodulation reference signal (DMRS) pattern-related field for the UE to transmit an uplink (UL) DMRS related to the subslot-based SPS PUSCH;
• and
• receiving uplink control information (UCI), in subslot n, from the UE through the subslot-based SPS PUSCH or through a PUCCH, based on whether the DMRS pattern-related field in the DCI is set to a first value,
• wherein the UCI is received through the subslot-based SPS PUSCH in the subslot n, without simultaneously receiving the PUCCH in the subslot n, based on the DMRS pattern-related field in the DCI being set to the first value,
• wherein the first value of the DMRS pattern-related field indicates that the UL DMRS is not mapped to at least one subslot among a plurality of subslots in which the subslot-based SPS PUSCH is received.

A user equipment (UE) configured for simultaneous physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH) transmission in a wireless communication system, the UE comprising:

• a transceiver;
• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:
• receiving, through a physical downlink control (PDCCH) via the transceiver, downlink control information (DCI) regarding subslot-based semi-persistent scheduling (SPS) PUSCH, wherein the DCI includes a demodulation reference signal (DMRS) pattern-related field for the UE to transmit an uplink (UL) DMRS related to the subslot-based SPS PUSCH;
• determining whether to transmit uplink control information (UCI), in subslot n, through the subslot-based SPS PUSCH, without simultaneously transmitting a PUCCH in the subslot n, based on whether the DMRS pattern-related field in the DCI is set to a first value;
• and
• transmitting, via the transceiver, the UCI through the subslot-based SPS PUSCH in the subslot n, without simultaneously transmitting the PUCCH in the subslot n, based on the DMRS pattern-related field in the DCI being set to the first value,
• wherein the first value of the DMRS pattern-related field indicates that the UL DMRS is not mapped to at least one subslot among a plurality of subslots in which the subslot-based SPS PUSCH is transmitted.

• receiving, from the UE via the transceiver in subslot n, uplink control information (UCI) through the subslot-based SPS PUSCH or through a PUCCH, based on whether the DMRS pattern-related field in the DCI is set to a first value,
• wherein the UCI is received through the subslot-based SPS PUSCH in the subslot n, without simultaneously receiving the PUCCH in the sub slot n, based on the DMRS pattern-related field in the DCI being set to the first value,
• wherein the first value of the DMRS pattern-related field indicates that the UL DMRS is not mapped to at least one subslot among a plurality of subslots in which the subslot-based SPS PUSCH is received.
