  • Methods, systems, and computer readable media for implementing a generalized model for defining application state machines
    Patent number: 11381464
    Abstract: Methods, systems, and computer readable media for testing and modeling the beamforming capabilities of a device under test (DUT) are disclosed. The method includes receiving, from a DUT, system information that correlates a plurality of resources to a plurality of synchronization system (SS) blocks transmitted by the DUT and receiving, from the DUT, the plurality of SS blocks. In response to receiving the plurality of SS blocks, the method further includes sending a random access procedure (RACH) message from an emulated user equipment to the DUT via a resource that is correlated per the system information to a predefined SS block that is specified in a beam model. The method also includes analyzing a beam switch indication message sent by the DUT to confirm that the DUT has restricted communication to the emulated user equipment via a beam signal corresponding to the predefined SS block.
