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

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

• at least one processor;
• and
• at least one computer memory operably coupled to the at least one processor and when executed, causing the at least one processor to perform an operation,
• wherein the operation includes:
• receiving resource allocation (RA) information for a physical uplink shared channel (PUSCH) transmission in a bandwidth part (BWP), wherein
• the BWP includes a plurality of subbands (SBs), each SB including a plurality of consecutive resource blocks (RBs),
• a guard band (GB) is included between the plurality of SBs, and
• the RA information indicates non-consecutive SB indexes;
• and
• performing the PUSCH transmission in an RB interlace within SBs corresponding to the non-consecutive SB indexes, based on the RA information, and
• wherein based on the non-consecutive SB indexes including at least two consecutive SB indexes, at least one GB interposed between SBs corresponding to the at least two consecutive SB indexes is valid as a resource for the PUSCH transmission.
