Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-type timing advance indicator is used for all connections, then device complexity is reduced, but timing synchronization accuracy deteriorates for multi-hop networks
Solution Approach 1:
The patent segments the timing advance indicator into two distinct types: first-type timing advance indicators for access connections and second-type timing advance indicators for backhaul connections. This segmentation allows each indicator type to be optimized for its specific connection type, with the second-type indicator providing enhanced bit quantity and granularity for multi-hop backhaul connections, thereby resolving the contradiction between device complexity and timing synchronization accuracy.
Solution Approach 2:
The patent applies local quality by configuring different timing advance indicator characteristics for different connection types. Specifically, second-type timing advance indicators used in backhaul connections have enhanced properties (greater bit quantity, finer granularity) compared to first-type indicators used in access connections. This localized optimization ensures high timing synchronization accuracy for multi-hop networks without unnecessarily increasing complexity for all device types.
2Measurement precision
If enhanced bit quantity and granularity are used for timing advance indicators, then timing synchronization accuracy is improved, but device complexity increases
Solution Approach 1:
The patent implements local quality by applying enhanced timing advance indicator characteristics (greater bit quantity, finer granularity) only where needed - specifically for second-type timing advance indicators in backhaul connections. First-type indicators for access connections maintain simpler structures. This localized enhancement improves timing configuration accuracy for multi-hop networks without unnecessarily increasing device complexity across the entire system.
Solution Approach 2:
The patent changes key parameters of the timing advance indicator - specifically increasing bit quantity and improving granularity - but applies these parameter changes selectively to second-type indicators for backhaul connections. This parameter optimization enables higher timing configuration accuracy for multi-hop networks while controlling overall device complexity through selective application.
3Ease of operation
If single-type timing advance indicators are used, then ease of operation is maintained, but positioning accuracy deteriorates
Solution Approach 1:
The patent segments timing advance indicators into first-type and second-type indicators with distinct characteristics. Second-type indicators provide enhanced precision for positioning-critical backhaul connections through greater bit quantity and finer granularity, while first-type indicators maintain simplicity for access connections. This segmentation resolves the contradiction by providing differentiated precision where needed without complicating overall operation.
Solution Approach 2:
The patent applies local quality by configuring enhanced timing advance indicator properties specifically for backhaul connections where positioning accuracy is critical. First-type indicators for access connections maintain simpler structures. This localized precision enhancement improves positioning accuracy in multi-hop networks without unnecessarily complicating the timing advance configuration for all device types.
4Adaptability or versatility
If distinct timing advance indicators are implemented for different connections, then network hop support is increased, but device complexity increases
Solution Approach 1:
The patent segments timing advance indicators into specialized first-type and second-type indicators, with second-type indicators designed specifically to support multi-hop backhaul connections. This segmentation enables the network to support more hops by providing appropriate timing precision for each connection type, while the clear differentiation between indicator types actually simplifies management compared to a single complex indicator system.
Solution Approach 2:
The patent creates a universal timing advance indicator framework where two indicator types serve different connection functions. First-type indicators handle access connections while second-type indicators handle backhaul connections, including multi-hop scenarios. This multi-functional approach increases network hop support capability while maintaining manageable device complexity through clear role differentiation and standardized procedures for each indicator type.
