1. A method for managing model updates by a first zone server associated with a first zone model of a plurality of zone models, comprising:
receiving, at the first zone server, a global model from a global server associated with the global model;
transmitting, from the first zone server, the global model to user equipment (UEs) in a first group of UEs of a plurality of groups of UEs, the first group of UEs associated with the first zone model, each group of UEs of the plurality of groups of UEs associated with a respective zone model of the plurality of zone models, each zone model of the plurality of zone models associated with the global model;
receiving, at the first zone server from two or more UEs in the first group of UEs, model updates associated with the global model based on transmitting the global model;
transmitting, from the first zone server to the global server, an average of the model updates received from the two or more UEs;
updating, at the first zone server, one or more weights of the global model in accordance with the average of the model updates to generate the first zone model based on receiving the model updates; and
transmitting, from the first zone server, the first zone model to the first group of UEs.
