Abstract

Certain aspects of the present disclosure provide techniques for reporting of a beam correspondence state. Certain aspects provide a method for wireless communication by a first wireless device. The method includes, based on detecting the occurrence of a triggering event, determining one or more beam correspondence states for one or more beams or portions of beams used by the first wireless device for communication. The method further includes transmitting one or more indications of the one or more beam correspondence states to a second wireless device, wherein the one or more indications of the one or more beam correspondence states indicate whether the first wireless device has the capability of beam correspondence between the one or more beams and corresponding one or more transmit or receive beams used by the first wireless device for communication.
