    Abstract: The present disclosure provides a method for performing federated learning by one user equipment (UE) with a plurality of user equipments (UEs) in a wireless communication system. More specifically, the method performed by one UE comprises receiving, from a base station, restriction information related to an order restriction for an information field for generating a local parameter transmitted by the one UE to perform the federated learning; performing encoding on the local parameter generated from an order restricted information field based on the restriction information, wherein the encoded local parameter consists of a systematic bit part and a parity part; performing modulation on the encoded local parameter, wherein the modulation is performed in different ways for each of the systematic bit part and the parity part; and transmitting, to the base station, a signal including the modulated local parameters.

    Abstract: A method for performing reinforcement learning by a V2X communication device in an autonomous driving system, specifically, a method for performing reinforcement learning in consideration of a reward application ratio over time, is proposed. Action information is transmitted to a second V2X communication device, reward information is received from the second V2X communication device, and reinforcement learning is performed on the basis of a reward, wherein a reward corresponding to a ratio determined by a first V2X communication device is applied to the reinforcement learning, the ratio is determined on the basis of a time interval from a time point of transmission of the action information to a time point of reception of the reward information, and the ratio is between 0 and 1, both inclusive.
