1Area of stationary object
If antenna elements are distributed over a large area in D-maMIMO systems, then network coverage and spatial multiplexing performance are improved, but installation complexity and cabling requirements increase significantly
Solution Approach 1:
The antenna array is segmented into multiple independent antenna elements that can be distributed along a flexible cable structure. Each antenna element operates independently but contributes to the overall MIMO system, allowing the array to be deployed over large areas while maintaining manageable installation complexity through modular segmentation.
Solution Approach 2:
The patent employs a flexible cable structure that can be easily deployed and configured in various spatial arrangements. This flexible medium allows the antenna elements to be distributed over large areas without requiring complex rigid support structures or extensive cabling infrastructure, thereby reducing installation complexity while maintaining area coverage.
2Productivity
If a large number of antenna elements are deployed, then system throughput and energy efficiency are improved, but hardware complexity and cost increase
Solution Approach 1:
Multiple antenna elements are merged into a unified flexible cable structure that provides both mechanical support and electrical interconnection. This merging approach reduces the overall hardware complexity by eliminating the need for separate mounting structures, power supplies, and control electronics for each individual antenna element, while still achieving high system throughput through coordinated operation of all elements.
Solution Approach 2:
The flexible cable structure serves multiple functions simultaneously: it provides mechanical support for antenna elements, electrical interconnection for signal transmission, and a configurable spatial framework for deployment. This multi-functionality reduces hardware complexity by eliminating the need for separate components for each function, while enabling the deployment of large numbers of antenna elements for high throughput.
3Measurement precision
If antenna elements are placed in fixed precise positions, then beamforming accuracy is improved, but installation time and cost increase
Solution Approach 1:
The flexible cable structure allows the antenna element positions to be dynamically adjusted during installation and operation. The cable can be bent, shaped, and configured to achieve the desired spatial distribution without requiring precise fixed mounting positions. This dynamic flexibility maintains beamforming accuracy through software-based position compensation while dramatically reducing installation time and cost.
Solution Approach 2:
The system compensates for variations in antenna element positions by changing the parameters used in beamforming calculations. Instead of requiring fixed precise physical positions, the system adapts the beamforming algorithms to account for the actual positions achieved during flexible deployment, thereby maintaining accuracy without increasing installation complexity or time.
