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

A user equipment (UE) configured to transmit an uplink channel in a wireless communication system, the UE comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one memory storing instructions that, when executed, cause the at least one processor to perform operations comprising:
• monitoring, in a common search space (CSS), a physical uplink control channel (PDCCH) candidates for a downlink control information (DCI) format used for scheduling of a physical uplink shared channel (PUSCH);
• and
• transmitting the PUSCH based on detecting a PDCCH with the DCI format,
• wherein resource allocation of the PUSCH is determined based on indicated interlaces and an uplink resource block set (uplink RB-set), and
• wherein the uplink RB-set is a lowest indexed one among uplink RB-set(s) that intersects a lowest indexed control channel element (CCE) of a physical downlink control channel (PDCCH) in which the DCI format is detected, and
• wherein, if there is no uplink RB-set that intersects the lowest indexed CCE of the PDCCH, the uplink RB-set is an uplink RB-set with a lowest index in an uplink bandwidth part (BWP).

A base station (BS) configured to receive an uplink channel in a wireless communication system, the BS comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one memory storing instructions that, when executed, cause the at least one processor to perform operations comprising:
• transmitting, in a common search space (CSS), a physical uplink control channel (PDCCH) candidates for a downlink control information (DCI) format used for scheduling of a physical uplink shared channel (PUSCH);
• and
• receiving the PUSCH based on transmitting a PDCCH with the DCI format,
• wherein resource allocation of the PUSCH is determined based on indicated interlaces and an uplink resource block set (uplink RB-set), and
• wherein the uplink RB-set is a lowest indexed one among uplink RB-set(s) that intersects a lowest indexed control channel element (CCE) of a physical downlink control channel (PDCCH) in which the DCI format is transmitted, and
• wherein, if there is no uplink RB-set that intersects the lowest indexed CCE of the PDCCH, the uplink RB-set is an uplink RB-set with a lowest index in an uplink bandwidth part (BWP).
