Method for performing federated learning in wireless communication system, and apparatus therefor

A user equipment (UE) configured to perform federated learning in a wireless communication system, the UE comprising:

• at least one transceiver;
• at least one processor functionally connected to the at least one transceiver;
• and
• at least one memory functionally connected to the at least one processor, and storing instructions for causing the at least one processor to perform operations,
• wherein the operations includes:
• generating a Q-ary code including i) a restriction-based system part and ii) a parity part by coding restriction-based Q-ary information;
• determining a number of transmissions (T) of the parity part among the Q-ary code based on a preconfigured way;
• allocating power to the system part and T parity parts based on specific channel information among channel information between a plurality of UEs and a base station participating in the federated learning;
• and
• transmitting the system part and the T parity parts to the base station based on the allocated power.

A method for performing federated learning in a wireless communication system, the method performed by a base station comprising:

• receiving a system part and T parity parts from a user equipment (UE) based on allocated power,
• wherein the system part and parity parts are generated by coding restriction-based Q-ary information,
• wherein a number of transmissions (T) of the parity part is determined based on a preconfigured way, and
• wherein the allocated power of the system part and T parity parts is determined based on specific channel information among channel information between a plurality of UEs and a base station participating in the federated learning.
