Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If resource configuration information is distributed to all terminal devices via network device, then information sharing is achieved, but network overhead and complexity increase
Solution Approach 1:
The patent introduces terminal devices as intermediaries to distribute resource configuration information within their groups. Instead of the network device directly managing all terminal devices, each terminal device acts as a local distributor for its group members, reducing network overhead while ensuring information reaches all devices efficiently.
Solution Approach 2:
The patent divides terminal devices into multiple groups, with each group receiving and distributing resource configuration information independently. This segmentation allows parallel information distribution across groups, reducing overall network complexity and enabling localized management of resource configurations.
2Adaptability or versatility
If terminal devices transmit data independently, then communication flexibility is improved, but interference between devices increases
Solution Approach 1:
The patent assigns different resource configurations (time slots, frequency resources, spatial parameters) to different terminal devices or groups within the same cell. This local differentiation ensures that while devices transmit independently with flexibility, their transmissions do not interfere with each other due to orthogonal or separated resource allocation.
Solution Approach 2:
The patent enables dynamic resource allocation where terminal devices can adaptively select from available resource configurations based on current channel conditions, traffic requirements, and group coordination. This dynamic approach maintains communication flexibility while the network device coordinates allocations to prevent interference.
3Extent of automation
If resource allocation is centralized by network device, then resource management control is improved, but response time and efficiency decrease
Solution Approach 1:
The patent implements semi-persistent scheduling where the network device allocates resource configurations in advance for periodic use. Terminal devices receive resource configurations that are valid for multiple transmission occasions without requiring repeated network signaling, thus maintaining centralized control while significantly reducing response time for ongoing transmissions.
Solution Approach 2:
The patent enables terminal devices to autonomously select and use pre-allocated resource configurations from their assigned sets. Once the network device provides resource configurations, terminal devices can independently make transmission decisions based on local conditions without continuous network intervention, achieving both control and efficiency.
