Beam management based on event triggered measurement reporting

Abstract

Methods, computer instructions, and systems for beam management based on triggered events, which may include receiving at a wireless device configuration parameters that include one or more reference signals (RSs), a plurality of transmission configuration indicator (TCI) states each corresponding to a beam, and a threshold value. The wireless device receives a command activating one or more of the plurality of TCI states. The wireless device transmits a beam measurement report in response to a measured quality of at least one of the RSs being a threshold value better than the RS associated with one of the activated TCI states, where the beam measurement report includes an identifier of the at least one RS. Upon receiving confirmation or acknowledgment message of the report from the base station, the wireless device updates the one or more TCI states with a TCI state associated with the at least one RS.
