Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single protocol version is implemented across all devices, then implementation complexity is reduced, but adaptability to different device capabilities and network conditions deteriorates
Solution Approach 1:
The patent implements dynamic protocol version selection where UEs can switch between different protocol versions (e.g., Release 17 and Release 18) based on network conditions, device capabilities, and traffic requirements. The network can dynamically indicate which protocol version to use through DCI or RRC signaling, allowing the system to adapt to changing conditions without requiring all devices to support all protocol versions simultaneously.
2Adaptability or versatility
If multiple protocol versions are supported simultaneously, then adaptability to different technologies is improved, but device complexity and resource management difficulty increase
Solution Approach 1:
The patent applies local quality by allowing different parts of the system to use different protocol versions based on their specific requirements. Specifically, different UEs or different communication links can operate with different protocol versions simultaneously, with each UE configured to use the appropriate version for its specific capabilities and service requirements, rather than requiring uniform protocol support across the entire system.
Solution Approach 2:
The network performs preliminary configuration of protocol version capabilities during UE initialization or connection setup. The network determines which protocol versions a UE supports and configures the appropriate version before data transmission begins, preventing the need for complex runtime protocol negotiation and reducing device complexity during actual communication.
3Productivity
If protocol optimization is performed for specific device types, then communication efficiency is improved, but system complexity and configuration difficulty increase
Solution Approach 1:
The patent implements self-service mechanisms where UEs automatically report their capability information (including supported protocol versions) to the network, and the network automatically selects and configures the appropriate protocol version based on UE capabilities and network conditions. This eliminates the need for manual configuration or complex negotiation protocols, as the system self-optimizes based on automatically exchanged capability information.

AI summary
A first wireless device transmits a first sidelink transmission via a first resource, where the first sidelink transmission includes a field indicating resource reservation of a second resource for a second sidelink transmission by the first wireless device. Based on an absence of an acknowledgement (ACK) corresponding to the first sidelink transmission, the first wireless device determines to use the second resource to receive inter user equipment (inter-UE) coordination information from a second wireless device. The first wireless device receives, from the second wireless device and based on the determining, the inter-UE coordination information indicating a set of third resources for one or more third sidelink transmissions by the first wireless device.
