Methods, systems, and devices for wireless communications are described. A first base station may receive, from a plurality of user equipments (UEs), a plurality of uplink signals that include feedback information for the plurality of UEs. A first UE of the plurality of UEs may be associated with the first base station and a second UE of the plurality of UEs may be associated with a second base station. The first base station may modify a plurality of sets of beam weights for a plurality of downlink signals, where each modified set of beam weights corresponds to a respective downlink signal of the plurality of downlink signals. The first base station may transmit, to the first UE, a first downlink signal of the plurality of downlink signals using a first modified set of beam weights of the of the plurality of sets of beam weights.
