Methods, systems, and devices for wireless communications are described to support estimation of a transmission quality imbalance between a set of antennas of a first user equipment (UE). The first UE may use the estimated transmission quality imbalance to determine a transmission diversity scheme that may decrease the transmission quality imbalance. The first UE may determine the transmission quality imbalance between the set of antennas by estimating a reception quality imbalance between the set of antennas. The first UE may estimate the reception quality imbalance for multiple subsets of a time period and may combine the reception quality imbalance estimations for the multiple subsets. The combined reception quality imbalance estimations may represent the transmission quality imbalance between the set of antennas, which may be used to determine a transmission diversity scheme for communicating a transmission to a second UE or a base station.
