UE Beam Group Reporting for Lower-Overhead Downlink Beam Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in wireless communication systems using beamforming technology is the inefficient selection and reporting of candidate transmit beams by user equipment, leading to increased signaling overhead and suboptimal beam selection for downlink information transmission.
Innovation Solution
The user equipment selects and reports multiple groups of transmit beams to the network side device, allowing simultaneous reception of downlink information using multiple beams, thereby reducing signaling overhead and improving beam selection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE reports multiple candidate transmit beams individually, then the beam selection accuracy is improved, but the signaling overhead increases
Solution Approach 1:
The patent segments the K candidate transmit beams into multiple groups, where each group contains multiple beam indices. Instead of reporting each beam individually, the UE reports grouped beam information, reducing the number of signaling messages while preserving beam selection accuracy through the group structure.
Solution Approach 2:
The patent merges multiple beam candidate reports into grouped beam information. By combining multiple beam indices into groups and reporting these groups collectively, the signaling overhead is reduced while the network side device can still identify the optimal transmit beam from the grouped candidates.
2Reliability
If the network side device transmits downlink information using multiple transmit beams simultaneously, then the transmission reliability is improved, but the device complexity increases
Solution Approach 1:
The patent enables dynamic beam selection where the network side device can adaptively choose from multiple candidate transmit beams based on channel conditions. The system dynamically adjusts the transmit beam configuration, allowing reliable multi-beam transmission when needed while simplifying to single-beam operation when conditions permit, thus managing device complexity.
Solution Approach 2:
The patent changes the beam configuration parameters by selecting different numbers of candidate beams (K) and group sizes based on channel conditions and service requirements. This parameter adaptation allows the system to optimize between transmission reliability and device complexity by adjusting beam-related parameters dynamically.
