Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing beam allocation methods in high-frequency antenna base stations are limited by the number of TRXs, resulting in restricted beam coverage and waiting latency for user equipment within coverage of beams in other directions, leading to inefficient spectrum utilization.
Innovation Solution
The method involves performing linear superposition on antenna weights to generate multiple beams in different directions simultaneously, allowing for expanded coverage and concurrent data transmission without waiting latency, and optimizing beam allocation to improve spectrum utilization by reallocating beams based on interference and resource availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If one TRX generates only one beam in one direction at a same moment, then the beam generation is simple and controlled, but the beam coverage is limited and waiting latency occurs for user equipment
Solution Approach 1:
The patent segments the single beam generation function into multiple simultaneous beam generation capabilities. By dividing the TRX's capabilities across multiple antenna weights (first, second, and third antenna weights), the system can generate multiple beams in different directions simultaneously, thereby expanding beam coverage and eliminating waiting latency for user equipment in different directions.
Solution Approach 2:
The patent transitions from single-dimensional beam generation (one direction at a time) to multi-dimensional beam generation (multiple directions simultaneously). By utilizing multiple antenna weights to create beams in different spatial directions at the same moment, the system expands coverage across multiple dimensional spaces, resolving the coverage and latency contradiction.
2Area of stationary object
If multiple beams are generated simultaneously by one TRX using linear superposition of antenna weights, then beam coverage is expanded and waiting latency is eliminated, but the device complexity increases
Solution Approach 1:
The patent merges multiple antenna weight sets (first, second, and third antenna weights) into a unified beam generation process using linear superposition. By combining these antenna weights to simultaneously generate multiple beams, the system achieves expanded beam coverage while managing device complexity through a standardized superposition approach rather than separate processing for each beam.
Solution Approach 2:
The patent creates a universal antenna weight processing mechanism that can generate multiple beams simultaneously through linear superposition. This multi-functional approach allows the same TRX to serve multiple directions and user equipments concurrently, reducing the need for additional dedicated hardware for each beam direction and thereby managing device complexity.
3Productivity
If beams are allocated sequentially to user equipments, then the allocation process is simple and controlled, but spectrum utilization is low due to waiting latency
Solution Approach 1:
The patent implements continuous useful action by enabling simultaneous beam generation and allocation to multiple user equipments. Instead of sequential allocation that creates idle time and waiting latency, the system continuously utilizes the TRX to generate and allocate multiple beams concurrently through linear superposition, thereby maximizing spectrum utilization without significant increases in allocation complexity.
