1. A method for wireless communications at a first device, comprising:
transmitting, for a second device, a capability indicating a status for dynamic beam correspondence with the second device, transmission of the capability being based at least in part on a first set of antenna elements being different from a second set of antenna elements, the first set of antenna elements used for downlink communications with the second device, and the second set of antenna elements used for uplink communications with the second device, the capability further indicating at least a first beam correspondence capability for a first transmission time interval and a second beam correspondence capability for a second transmission time interval;
receiving, from the second device, an indication of an operating mode to use for communications with the second device, the operating mode being based at least in part on the capability; and
communicating with the second device based at least in part on the indication of the operating mode.
