Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beam-based cell coverage systems in mobile communication networks struggle to accurately identify the location of terminal devices within the cell, as devices at the center and edge receive varying coverage strengths, leading to inefficiencies in network identification and resource allocation.
Innovation Solution
Implementing a wireless communication method that utilizes multiple beam layers, each corresponding to distinct coverage areas within a cell, allowing for more precise identification of device location through beam scanning and configuration of beam layers, and adjusting parameters such as random access resources and signal qualities based on beam layer-specific characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single beam is used to cover a cell, then the beam structure is simple, but the network cannot accurately identify the location of terminal devices in different areas
Solution Approach 1:
The patent divides the cell into multiple coverage areas by introducing multiple beam layers (first beam layer, second beam layer, etc.), where each beam layer corresponds to a specific spatial region. This segmentation allows the network to identify which beam layer a terminal device is in, thereby improving location identification precision while maintaining manageable structural complexity through systematic organization of beams into layered groups.
Solution Approach 2:
The patent transitions from a single-beam coverage model to a multi-layer beam structure, adding a vertical dimension (beam layer index) to the traditional horizontal beam arrangement. This dimensional expansion enables the network to distinguish between terminal devices at different radial distances from the cell center, achieving finer-grained location identification without proportionally increasing overall system complexity.
2Measurement precision
If multiple beam layers are introduced to improve location identification, then the network can accurately determine device location, but the beam scanning and configuration complexity increases
Solution Approach 1:
By segmenting the beam structure into multiple layers with each layer serving a specific spatial region, the patent enables precise location identification while managing complexity through modular organization. Each beam layer can be scanned and configured independently, allowing the system to handle the increased number of beams in an organized manner.
Solution Approach 2:
The patent performs beam scanning and configuration in a predetermined sequence across different beam layers before terminal devices attempt initial access. This preliminary action ensures that the network is ready to accurately identify device locations and allocate resources efficiently, reducing the operational complexity of handling multiple beam layers during actual communication operations.
3Productivity
If beam layers are configured to cover different areas, then resource allocation can be optimized, but the initial access process becomes more complex
Solution Approach 1:
The patent assigns different beam layers to different spatial regions with each layer having specific coverage characteristics. Terminal devices in different areas are automatically served by the appropriate beam layer, enabling optimized resource allocation tailored to local conditions such as signal strength and interference levels, while the device simply needs to perform standard initial access procedures.
Solution Approach 2:
The patent enables terminal devices to autonomously determine which beam layer to access based on their location and signal conditions without requiring complex manual configuration. The device self-selects the appropriate beam layer for initial access, and the network automatically directs it to the correct resources, thereby maintaining simplicity in the device-side process while achieving efficient resource allocation.
