  • Abstract
    User-identity feedback was proposed to achieve multi-user diversity while minimizing feedback load. This letter mathematically shows that the transmit-power consumption of the user-identity feedback converges to zero as the number of users increases. Numerical results in a Rayleigh fading channel show that the transmit-power saving is substantial even with small number of users.
