Method and device for transmitting and receiving physical uplink shared channel in wireless communication system

A user equipment (UE) for transmitting a physical uplink shared channel (PUSCH) in a wireless communication system, the UE comprising:

• one or more transceivers;
• one or more processors;
• and
• one or more memories operatively connected to the one or more processors and storing instructions that, based on being executed by the one or more processors, configure the one or more processors to perform operations comprising:
• receiving downlink control information (DCI) for scheduling a PUSCH;
• and
• transmitting the PUSCH based on the DCI,
• wherein a format of the DCI is DCI format 0_0,
• wherein, based on that a physical uplink control channel (PUCCH) resource of a BWP related to the PUSCH is not configured:
• the PUSCH is transmitted based on spatial relation quasi-colocation (QCL) Reference Signal (RS) information of a predefined control resource set (CORESET), and
• the predefined CORESET is a CORESET having a lowest ID within an active bandwidth part (BWP).

A method of receiving a physical uplink shared channel (PUSCH) by a base station in a wireless communication system, the method comprising:

• transmitting downlink control information (DCI) for scheduling a PUSCH;
• and
• receiving the PUSCH which is transmitted based on the DCI,
• wherein a format of the DCI is DCI format 0_0,
• wherein, based on that a physical uplink control channel (PUCCH) resource of a BWP related to the PUSCH is not configured:
• the PUSCH is transmitted based on spatial relation quasi-colocation (QCL) Reference Signal (RS) information of a predefined control resource set (CORESET), and
• the predefined CORESET is a CORESET having a lowest ID within an active bandwidth part (BWP).

A base station for receiving a physical uplink shared channel (PUSCH) in a wireless communication system, the base station comprising:

• one or more transceivers;
• one or more processors;
• and
• one or more memories operatively connected to the one or more processors and storing instructions, based on being executed by the one or more processors, that configure the one or more processors to perform operations comprising:
• transmitting downlink control information (DCI) for scheduling a PUSCH;
• and
• receiving the PUSCH which is transmitted based on the DCI,
• wherein a format of the DCI is DCI format 0_0,
• wherein, based on that a physical uplink control channel (PUCCH) resource of a BWP related to the PUSCH is not configured:
• the PUSCH is received based on spatial relation quasi-colocation (QCL) Reference Signal (RS) information of a predefined control resource set (CORESET), and
• the predefined CORESET is a CORESET having a lowest ID within an active bandwidth part (BWP).
