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

A user equipment (UE) configured to transmit and receive a signal in a wireless communication system, the UE comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform operations comprising:
• performing a random access channel (RACH) procedure;
• receiving configuration information related to the UE based on the RACH procedure;
• detecting downlink control information (DCI) scheduling a single physical uplink shared channel (PUSCH) or multiple PUSCHs to be transmitted on a serving cell based on the configuration information;
• and
• transmitting the single PUSCH or the multiple PUSCHs on the serving cell based on the DCI,
• wherein a payload size of the DCI is determined based on a larger of a number of information bits for scheduling the single PUSCH and a number of information bits for scheduling the multiple PUSCHs.

An apparatus for a user equipment (UE), the apparatus comprising:

• at least one processor;
• and
• at least one computer memory operably connected to the at least one processor and configured to, when executed, cause the at least one processor to perform operations comprising:
