Signal transmission and reception method and device in wireless communication system

A UE receiving a signal in a wireless communication system, the UE comprising:

• one or more transceivers;
• one or more processors;
• and
• one or more memories operably connectable to the one or more processors and storing instructions, based on being executed by the one or more processors, which configure the one or more processor to perform operations comprising:
• receiving a configuration which is related to a resource region in which the signal is transmitted;
• and
• receiving the signal in the resource region based on the configuration,
• wherein a time domain resource of the resource region includes at least one symbol,
• wherein the at least one symbol belongs to at least one slot,
• wherein the at least one slot is based on at least one of one or more slots within a subframe,
• wherein the subframe is one of a number of subframes within a radio frame,
• wherein a number of the one or more slots within the subframe is determined based on an Orthogonal Frequency Division Multiplexing (OFDM) numerology related to the at least one symbol,
• wherein the signal is based on a signal down-converted in frequency based on an optical-to-electrical (O/E) converter,
• wherein a frequency domain resource of the resource region includes a plurality of chunks, and each chunk is composed of at least one component carrier (CC), wherein
• the configuration includes information representing a main chunk related to differential phase shift keying (DPSK),
• wherein transmission of the signal is based on the DPSK applied between the plurality of chunks based on the main chunk,
• wherein the main chunk includes a target frequency band of the O/E converter and the reception of the signal is based on decoding performed from the main chunk.

A method for transmitting a signal by a base station in a wireless communication system, the method comprising:

• transmitting a configuration which is related to a resource region in which the signal is transmitted;
• and
• transmitting the signal in the resource region based on the configuration,
• wherein a time domain resource of the resource region includes at least one symbol,
• wherein the at least one symbol belongs to at least one slot,
• wherein the at least one slot is based on at least one of one or more slots within a subframe,
• wherein the subframe is one of a number of subframes within a radio frame,
• wherein a number of the one or more slots within the subframe is determined based on an Orthogonal Frequency Division Multiplexing (OFDM) numerology related to the at least one symbol,
• wherein the signal is based on a signal down-converted in frequency based on an optical-to-electrical (O/E) converter,
• wherein a frequency domain resource of the resource region includes a plurality of chunks, and each chunk is composed of at least one component carrier (CC),
• wherein the configuration includes information representing a main chunk related to differential phase shift keying (DPSK),
• wherein transmission of the signal is based on the DPSK applied between the plurality of chunks based on the main chunk,
• wherein the main chunk includes a target frequency band of the O/E converter and the reception of the signal by the UE is based on decoding performed from the main chunk.
