Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only one wireless air interface technology is supported on one carrier, then the system is simple to operate and manage, but radio resource utilization is low and cannot meet diverse service requirements
Solution Approach 1:
The patent segments the carrier frequency resources by allocating different frequency ranges to different air interface technologies. The network device configures multiple frequency ranges on the same carrier, where each frequency range corresponds to a specific air interface technology, enabling simultaneous support for multiple technologies while maintaining clear resource boundaries and manageable complexity
Solution Approach 2:
The patent makes the carrier multi-functional by enabling it to support multiple air interface technologies simultaneously. The same carrier can serve as a resource for both first and second air interface technologies, with the network device dynamically allocating frequency ranges to different technologies based on service requirements, thus achieving universal resource utilization
2Productivity
If different services are transmitted using time division multiplexing or different carriers, then resource allocation is simplified, but radio resource utilization cannot be dynamically adjusted and delay performance deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation where the network device can flexibly adjust the frequency ranges allocated to different air interface technologies based on real-time service requirements. This dynamic adjustment capability allows the system to respond to varying traffic conditions and QoS requirements, optimizing resource utilization and reducing delay for time-sensitive services
Solution Approach 2:
The patent changes the allocation parameters of radio resources by configuring different frequency ranges for different air interface technologies on the same carrier. The network device can modify these frequency range allocations dynamically, allowing services with different QoS requirements to obtain appropriate resource allocations, thereby improving both resource utilization and delay performance
3Productivity
If multiple air interface technologies are supported on the same carrier with frequency division multiplexing, then radio resource utilization is enhanced and dynamic allocation is enabled, but the complexity of resource management increases
Solution Approach 1:
The patent incorporates feedback mechanisms where the terminal device reports channel conditions and service requirements to the network device. Based on this feedback, the network device intelligently adjusts the frequency range allocations for different air interface technologies, automating the resource management process and reducing the operational complexity despite supporting multiple technologies
