We discuss an approach proposed recently by us for the description of hot phonon dynamics in heterolayers. The nonequilibrium phonons are described as excitations localized near the carrier layer and a kinetic equation for these "phonon wavepacket" is obtained. Calculations of the cooling rate and mobility of hot electrons are compared with recent experiments.
