Downlink beam management using a configurable deflector

Abstract:

Methods, systems, and devices for wireless communications are described. Generally, the described techniques allow a channel engineering device (CED) to identify a suitable configuration for deflecting downlink transmissions from a base station to a user equipment (UE). The base station may transmit control signaling to the CED indicating multiple configurations for deflecting downlink reference signals from the base station. The base station may then transmit the downlink reference signals to the CED, and the CED may deflect the downlink reference signals using the indicated configurations. The UE may receive the downlink reference signals from the base station via the CED, and the UE may perform measurements on the downlink reference signals. The UE may then report the measurements to the base station, and the base station may indicate a configuration for the CED to use to deflect subsequent transmissions from the base station to the UE based on the measurements.
