Method and device for transmitting and receiving pusch in wireless communication system

A user equipment (UE) operating in a wireless communication system, the UE comprising:

• at least one transceiver for transmitting and receiving a wireless signal;
• and
• at least one processor for controlling the at least one transceiver,
• wherein the at least one processor configured to:
• receive first downlink control information (DCI) for scheduling first physical uplink shared channel (PUSCH) transmission and second DCI for scheduling second PUSCH transmission, wherein the first DCI and the second DCI are received in a first CORESET and a second CORESET, respectively, having different control resource set (CORESET) pool indices;
• and
• perform the first PUSCH transmission and the second PUSCH transmission based on different spatial relation reference signals (RS),
• wherein a first spatial relation RS for a specific PUCCH resource associated with a CORESET pool index of the first CORESET is used for the first PUSCH transmission.

A base station operating in a wireless communication system, the base station comprising:

• at least one transceiver for transmitting and receiving a wireless signal;
• and
• at least one processor for controlling the at least one transceiver,
• wherein the at least one processor configured to:
• transmit first downlink control information (DCI) for scheduling first physical uplink shared channel (PUSCH) transmission and second DCI for scheduling second PUSCH transmission, wherein the first DCI and the second DCI are transmitted in a first CORESET and a second CORESET, respectively, having different control resource set (CORESET) pool indices;
• and
• receive the first PUSCH transmission and the second PUSCH transmission based on different spatial relation reference signals (RS),
• wherein a first spatial relation RS for a specific PUCCH resource associated with a CORESET pool index of the first CORESET is used for the first PUSCH transmission.
