Configurable Deflector for Uplink Beam Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in reliably receiving uplink transmissions from user equipment (UE) to base stations due to obstructions, as existing beam management procedures do not effectively involve channel engineering devices (CEDs) in identifying suitable configurations for deflecting uplink signals.
Innovation Solution
The implementation of a method and system where a base station transmits control signaling to a CED indicating multiple configurations for deflecting uplink reference signals, allowing the CED to deflect these signals and enabling the base station to perform measurements to identify the optimal configuration for subsequent transmissions, which is then communicated back to the CED for use.

Engineering Contradiction Analysis
1Reliability
If a direct path is used for uplink transmissions from UE to base station, then the transmission path is simple, but the reliability is low due to obstructions
Solution Approach 1:
A configurable deflector is introduced as an intermediary device between the UE and base station to deflect uplink transmissions. The deflector receives control signaling from the base station indicating configurations for deflecting uplink reference signals, applies the indicated configuration to deflect signals around obstructions, and enables reliable communication without requiring complex multi-path routing
Solution Approach 2:
The deflector is configured dynamically based on channel conditions. The base station transmits control signaling indicating multiple configurations, the deflector applies different configurations based on measurements of uplink reference signals, and updates the deflection pattern adaptively to maintain reliable transmissions as conditions change
2Reliability
If multiple configurations are tested for deflecting uplink signals, then the reliability of transmission is improved, but the time required for configuration identification increases
Solution Approach 1:
The base station proactively transmits control signaling indicating multiple configurations for the deflector before uplink transmissions begin. This preliminary configuration setup allows the deflector to be ready with multiple potential configurations, reducing the time needed during actual transmission to identify the optimal configuration
Solution Approach 2:
The system implements a feedback mechanism where the base station measures uplink reference signals deflected by the configurable deflector and identifies the best configuration based on measurement results. This feedback loop enables efficient configuration selection by using actual transmission measurements to determine the optimal deflection configuration

AI summary
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 uplink transmissions from a user equipment (UE) to a base station. The base station may transmit control signaling to the CED indicating multiple configurations for deflecting uplink reference signals. The UE may then transmit the uplink reference signals to the CED, and the CED may deflect the uplink reference signals using the indicated configurations. The base station may receive the uplink reference signals from the UE via the CED, and the base station may perform measurements on the uplink reference signals. The base station may then identify a configuration for the CED to use to deflect subsequent transmissions from the UE to the base station based on the measurements, and the base station may transmit an indication of the configuration to the CED.
