Abstract
A first wireless device and a second device may negotiate a configuration of an RF chain calibration process with each other. The configuration of the RF chain calibration process may include a number of calibration rounds. The second wireless device may exchange, in each calibration round in the number of calibration rounds, at least one RS and at least one feedback message with the first wireless device. The second wireless device may identify one or more calibration adjustment parameters for the second wireless device based on the RF chain calibration process. The second wireless device may communicate with another wireless device based on the one or more calibration adjustment parameters.

An apparatus for wireless communication at a first wireless device, comprising:
- a memory;
- and
- at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
- negotiate a configuration of a radio frequency (RF) chain calibration process with a second wireless device, the configuration of the RF chain calibration process including a number of calibration rounds;
- and
- exchange, in each calibration round in the number of calibration rounds, at least one reference signal (RS) and at least one feedback message with the second wireless device based on the configuration of the RF chain calibration process.
