  • Patent number: 11251884
    Abstract: Techniques for process based antenna configuration are described, and may be implemented via a wireless device to identify different usage scenarios and to adapt antenna configurations to optimize wireless performance based on the scenarios. For instance, the described techniques enable a wireless device to be calibrated for wireless communication by identifying different obstruction states of a wireless device that correspond to ways that the wireless device is held (e.g., grasped) by a user in different scenarios. The obstruction states are then correlated to antenna positions in the wireless device to prioritize (e.g., activate) antennas that are relatively unobstructed, such as by activating unobstructed antennas and/or deactivating obstructed antennas. Further, calibration can take into specific processes (e.g., applications) and specific users to calibrate an optimize wireless performance based on ways in which a user typically interacts with a process.

    Abstract: Systems, apparatuses, and methods for scheduling beamforming training during vertical blanking intervals (VBIs) are disclosed. A system includes a transmitter sending a video stream over a wireless link to a receiver. The wireless link between the transmitter and the receiver has capacity characteristics that fluctuate with variations in the environment. To combat the fluctuating capacity characteristics of the link, the transmitter and the receiver perform periodic beamforming training procedures to determine whether to adjust the beamforming characteristics of their respective antennas. To avoid interfering with the video data being sent, the system waits until a VBI to perform a beamforming training procedure. If the beamforming training procedure cannot be completed in a single VBI, then multiple VBIs can be used for performing separate portions of the beamforming training procedure. In one embodiment, the system can perform a beamforming training procedure every N VBIs, where N is a positive integer.

A switch can be used to connect or disconnect one modal element from the array, with this feature providing additional unique array beam states. The modal array can be commanded via a look-up table or algorithm.
