Abstract: The present disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for channel state information report configuration for non-serving cell reference signal. A user equipment may receive, from a serving cell, a reference signal (RS) measurement configuration and a RS report configuration associated with a non-serving cell. The UE also may monitor for a RS beam using a transmission configuration indicator (TCI) state associated with the non-serving cell based on the RS measurement configuration. The UE also may obtain one or more measurements of the RS beam associated with the non-serving cell. The UE also may transmit, to the serving cell, a beam report indicating the one or more measurements of the RS beam associated with the non-serving cell and beam measurements associated with a serving cell based on the RS report configuration.
