We consider the non-equilibrium transport in a disordered 1D quantum wire taking into account the Coulomb interaction in the framework of the Luttinger liquid model (no curvature and no electron-electron backscattering). Using the non-equilibrium Keldysh technique the 1D sigma-model approach to the problem is formulated and the set of coupled quantum kinetic equations, governing the dynamics of relevant fermionic and bosonic excitations in the system, is derived. We further consider the disorder-induced energy relaxation, the non-equilibrium density of states, and the current noise in the wire.
