Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in transmitting uplink signals between user equipment (UE) and base stations, particularly in applying different beamforming schemes to various resource areas, which affects the reliability and latency of communication.
Innovation Solution
A method is introduced where the UE applies a different beamforming scheme to each predetermined resource area for efficient transmission of uplink signals, including control and data information, using a precoder cycling scheme to optimize signal transmission.

Engineering Contradiction Analysis
1Reliability
If a single beamforming scheme is applied to all resource areas, then device complexity is reduced, but communication reliability and adaptability deteriorate
Solution Approach 1:
The patent divides the uplink resource area into multiple segments (first resource area and second resource area) and applies different beamforming schemes to each segment. Specifically, a first beamforming scheme is applied to the first resource area while a second beamforming scheme is applied to the second resource area, allowing the system to optimize reliability for different resource types without requiring complex beamforming across the entire resource space.
Solution Approach 2:
The patent implements local quality optimization by selecting specific beamforming schemes for specific resource areas based on their characteristics. The first beamforming scheme is tailored for the first resource area while the second beamforming scheme is tailored for the second resource area, ensuring that each local region receives the most appropriate beamforming treatment for its specific requirements rather than applying a uniform scheme globally.
2Adaptability or versatility
If different beamforming schemes are applied to each resource area, then communication adaptability and reliability improve, but device complexity increases
Solution Approach 1:
The patent segments the uplink resources into distinct areas (first resource area and second resource area) and assigns different beamforming schemes to each segment. This segmentation allows the system to achieve high adaptability by optimizing beamforming for each resource area's specific characteristics while managing complexity through clear segmentation boundaries and standardized scheme selection within each segment.
3Productivity
If precoder cycling scheme is used for uplink transmission, then transmission efficiency improves, but processing complexity increases
Solution Approach 1:
The patent implements precoder cycling by periodically changing the precoding scheme across different resource areas. The system cycles through different precoders in a predetermined pattern, applying the first beamforming scheme to the first resource area and the second beamforming scheme to the second resource area. This periodic action improves transmission efficiency by adapting to channel variations while maintaining manageable processing complexity through the regular, predictable cycling pattern.
