Offloading beam tracking using a configurable deflector

Abstract:

Methods, systems, and devices for wireless communications are described. A base station may transmit, to a channel engineering device, a configuration for performing a downlink beam refinement procedure with a user equipment (UE). The channel engineering device may transmit one or more reference signals (e.g., one or more channel state information reference signals) to the UE. For instance, the channel engineering device may transmit the one or more reference signals to the UE over resources configured by the base station or may deflect (e.g., reflect, refract, or both) reference signals transmitted to the channel engineering device by the base station. After receiving the one or more reference signals, the UE may transmit a report to the channel engineering device that the channel engineering device may use to update a channel configuration of the channel engineering device (e.g., updating a downlink beam or angle of deflection at the channel engineering device).
