    Abstract: Systems and methods are provided for dynamic beam sweeping a synchronization signal based on historical usage patterns. In response to determining a recurring pattern of a plurality of user devices being disposed within a certain portion of a sector during a time period, a modified beam sweeping protocol may be implemented. The modified beam sweeping protocol decreases the average periodicity of a series of synchronization signals that are transmitted to a distinct portion of the sector using a distinct beamform, increasing the likelihood of synchronization between user devices and a network, decreasing interference and other undesirable network conditions.

  • Patent number: 11277192
    Abstract: A user equipment (UE) may monitor multiple beam pair links (BPLs) including a first BPL currently used by the UE to communicate with a network node (e.g., a base station), and a second BPL. The first BPL comprises a first network beam and a first UE beam, and the second BPL comprises a second network beam and a second UE beam. The UE may decide to switch beams from using the first BPL to using the second BPL based on signaling from the network node or autonomously. When the beam switch is made, the UE switches uplink (UL) transmission from over the first UE beam to over the second UE beam. After the beam switch is made, the UE transmits in the UL over the second UE beam using UL timing adjusted based on the first and second propagation delays.
