With the asymmetric resource sharing disclosed herein, a base station transmits fewer information symbols at some transmission times to one or more mobile terminals than to other mobile terminals at other transmission times. After transmitting the information symbols, the base station receives channel estimates from the mobile terminals, which the base station then use to generate synthesized signals representing estimates of the signals received at the mobile terminals. The base station subsequently combines complementary pairs of the synthesized signals to generate combined signals and transmits at least one of the combined signals to implement at least one virtual antenna for at least one of the mobile terminals.
