Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If simultaneous transmission with multi-panel (STxMP) is implemented, then data rate and transmission reliability are improved, but system complexity and resource coordination difficulty increase
Solution Approach 1:
The patent segments the uplink transmission function into multiple independent panels, where each panel can perform transmission independently. This segmentation allows simultaneous transmissions from multiple panels without requiring complex coordinated control, thereby improving data rate while managing system complexity through functional decomposition
Solution Approach 2:
The patent introduces a new dimension of spatial diversity by utilizing multiple panels for simultaneous transmission. This dimensional expansion from single-panel sequential transmission to multi-panel parallel transmission increases the data rate capability while the panel-level independence helps manage the complexity increase
2Reliability
If multiple PUSCH transmissions are scheduled from different CORESETs, then transmission reliability is improved, but resource allocation complexity increases
Solution Approach 1:
The patent segments the control resource allocation into multiple independent CORESETs, each associated with specific panels. This segmentation allows the base station to schedule PUSCH transmissions from different CORESETs independently, improving transmission reliability through diversity while managing resource allocation complexity through structured organization
Solution Approach 2:
The patent introduces panel-level abstraction as an intermediary layer between CORESET scheduling and physical transmission. This intermediary structure allows the base station to manage multiple CORESETs and panels independently, reducing the complexity of coordinating resources across multiple control sets while ensuring reliable transmission
3Productivity
If multi-panel simultaneous transmission is supported, then network capacity and service quality are improved, but terminal capability requirements and implementation difficulty increase
Solution Approach 1:
The patent segments the terminal's transmission capability into multiple independent panels, each capable of independent operation. This segmentation allows the terminal to implement multi-panel transmission by developing independent transmission chains for each panel, improving network capacity while managing implementation difficulty through modular design
Solution Approach 2:
The patent introduces capability indication mechanisms that allow terminals to declare their multi-panel support status in advance. This preliminary action enables the base station to appropriately configure and schedule multi-panel transmissions, improving network capacity while managing implementation difficulty by matching system requirements with terminal capabilities
