Method of transmitting or receiving sidelink signal in wireless communication system

An apparatus for a user equipment (UE) in a wireless communication system, the apparatus comprising:

• at least one processor;
• and
• at least one memory operably coupled to the at least one processor and storing at least one instruction which causes the at least one processor to perform operations,
• wherein the operations include:
• receiving a plurality of discovery signals in one of a plurality of bandwidth parts (BWPs);
• transmitting allocation information regarding remaining BWPs except for the one BWP among the plurality of BWPs in the one BWP, based on delay spread values of the plurality of respective discovery signals;
• and
• receiving a plurality of control signals and data signals in the remaining BWPs, and
• wherein the one BWP is configured to be used only with an extended cyclic prefix (CP), and the remaining BWPs are configured to be used only with a normal CP.

A processor for performing operations for a user equipment (UE) in a wireless communication system,

• wherein the operations include:
• receiving a plurality of discovery signals in one of a plurality of bandwidth parts (BWPs);
• transmitting allocation information regarding remaining BWPs except for the one BWP among the plurality of BWPs in the one BWP, based on delay spread values of the plurality of respective discovery signals;
• and
• receiving a plurality of control signals and data signals in the remaining BWPs, and
• wherein the one BWP is configured to be used only with an extended cyclic prefix (CP), and the remaining BWPs are configured to be used only with a normal CP.

A non-transitory computer-readable storage medium storing at least one computer program including at least one instruction which, when executed by at least one processor, causes the at least one processor to perform operations for a user equipment (UE),

• wherein the operations include:
• receiving a plurality of discovery signals in one of a plurality of bandwidth parts (BWPs);
• transmitting allocation information regarding remaining BWPs except for the one BWP among the plurality of BWPs in the one BWP, based on delay spread values of the plurality of respective discovery signals;
• and
• receiving a plurality of control signals and data signals in the remaining BWPs, and
• wherein the one BWP is configured to be used only with an extended cyclic prefix (CP), and the remaining BWPs are configured to be used only with a normal CP.
