  • Patent number: 10447366
    Abstract: Techniques for synchronized reception beam refinement are described herein. A base station may indicate to a user equipment (UE) a time when a reception beam refinement event may occur. The UE may initiate a synchronized reception beam refinement procedure based on receiving the indication from the base station. The UE may identify a new reception beam configuration based on data stored locally by the UE and ongoing background calculations that the UE carries out based on periodic beam reference signals. At the time indicated, the UE may adjust the reception beam configuration of a reception beam. The base station may initiate one or more link maintenance procedures based on a reception beam refinement event occurring. Such techniques may reduce the loss of data due to link degradation related to channel state feedback inconsistency (CSF) after a reception beam refinement event.
