In this paper, we investigate the uplink power allocation problem in a large scale environment for user devices with multi-homing capabilities. We introduce an analytical model for multi-homing ultra-dense heterogeneous networks, which takes into account spatial randomness and user device diversity. Coupling stochastic geometry analysis and mean-field approximation, we formulate the problem as a mean-field optimal control with two populations. Then, the optimality conditions are derived using Lagrangian dual formulation to obtain the mean-field equilibrium. Finally, by using a finite difference method, we illustrate the optimal transmit power for both uni-homed and dual-homed devices.
