Method and apparatus for transmitting and receiving signal including payload header in wireless communication system

A user equipment (UE) in an AIoT (Ambient Internet of Things) system, comprising:

• memory storing one or more instructions;
• and
• at least one processor;
• wherein the at least one processor is configured to execute the one or more instructions stored in the memory to:
• receive at least one payload header in a downlink signal, the at least one payload header including information related to an identity of the UE;
• and
• receive at least one payload corresponding to the at least one payload header in the downlink signal based on the information related to the identity of the UE.

A node in an AIoT (Ambient Internet of Things) system, comprising:

• memory storing one or more instructions;
• and
• at least one processor;
• wherein the at least one processor is configured to execute the one or more instructions stored in the memory to:
• transmitting at least one payload header in a downlink signal, the at least one payload header including information related to an identity of an intermediate node and/or a base station;
• and
• transmitting at least one payload corresponding to the at least one payload header in the downlink signal based on the information related to the identity of the intermediate node and/or the base station.
