Transmission imbalance estimation

An apparatus for wireless communications at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, over a time period, a plurality of reference signals at a plurality of antennas of the UE;
• estimate a measure of a reception quality imbalance between the plurality of antennas for each subset of a plurality of subsets of the time period based at least part on receiving the plurality of reference signals;
• determine, for the time period, a measure of a transmission quality imbalance between the plurality of antennas based at least in part on estimating the measure of the reception quality imbalance;
• and
• determine a transmit diversity scheme for the plurality of antennas based at least in part on the measure of the transmission quality imbalance.

An apparatus for wireless communications at a user equipment (UE), comprising:

• means for receiving, over a time period, a plurality of reference signals at a plurality of antennas of the UE;
• means for estimating a measure of a reception quality imbalance between the plurality of antennas for each subset of a plurality of subsets of the time period based at least part on receiving the plurality of reference signals;
• means for determining, for the time period, a measure of a transmission quality imbalance between the plurality of antennas based at least in part on estimating the measure of the reception quality imbalance;
• and
• means for determining a transmit diversity scheme for the plurality of antennas based at least in part on the measure of the transmission quality imbalance.

A non-transitory computer-readable medium storing code for wireless communications at a user equipment (UE), the code comprising instructions executable by a processor to:

• receive, over a time period, a plurality of reference signals at a plurality of antennas of the UE;
• estimate a measure of a reception quality imbalance between the plurality of antennas for each subset of a plurality of subsets of the time period based at least part on receiving the plurality of reference signals;
• determine, for the time period, a measure of a transmission quality imbalance between the plurality of antennas based at least in part on estimating the measure of the reception quality imbalance;
• and
• determine a transmit diversity scheme for the plurality of antennas based at least in part on the measure of the transmission quality imbalance.
