Abstract

Systems and methods are provided for a user equipment to train a transmit beam of a transmission configuration indication (TCI) for a non-serving cell. A system may use uplink (UL) reference signal (RS) based transmit (Tx) beam training with a target non-serving cell. The Target non-serving cell may measure the UL RS and determine a best Tx beam. The system may coordinate information regarding the best Tx beam to update a TCI at the UE for the target non-serving cell.
