Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current MTC and NB-IoT technologies struggle to meet the requirements of medium-end IoT devices, particularly in terms of bandwidth and delay, which are insufficient for services like video monitoring and smart home applications, and the sidelink communication in 5G NR systems faces limitations due to unoptimized resource pool configurations.
Innovation Solution
The proposed solution involves configuring resource pools with frequency domain bandwidths that align with the bandwidth capability range of specific terminal types, such as Redcap terminals, to ensure compatible and efficient sidelink communication, including determining resource pool configuration information and sending it to network devices to support different terminal capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If resource pools are configured with large frequency domain bandwidth to support high data rate, then the data rate requirement for medium-end IoT services is met, but the bandwidth capability range of Redcap terminals is exceeded
Solution Approach 1:
The patent applies local quality by configuring resource pools with different frequency domain bandwidths according to the specific capability requirements of different terminal types. For Redcap terminals, resource pools with bandwidth within their capability range are configured, while other terminal types can access resource pools with larger bandwidths. This localized adaptation ensures each terminal type receives appropriate resource configuration matching its capabilities.
Solution Approach 2:
The patent implements dynamics by enabling flexible configuration of resource pool bandwidths based on terminal capabilities. The system can dynamically adjust which resource pools are configured for which terminal types, allowing the network to adapt resource allocation in real-time based on the terminal's bandwidth capability, thus resolving the contradiction between providing high data rate and maintaining compatibility.
2Device complexity
If existing MTC and NB-IoT technologies are used to support IoT services, then device simplicity is maintained, but the bandwidth and delay requirements for video monitoring and smart home services are not met
Solution Approach 1:
The patent applies universality by designing a unified resource pool configuration mechanism that serves multiple terminal types including Redcap terminals, MTC terminals, and NB-IoT terminals. The system can configure resource pools with appropriate bandwidths for different service requirements while maintaining a single, manageable configuration framework, thus achieving high performance without proportionally increasing device complexity.
Solution Approach 2:
The patent utilizes parameter changes by adjusting the frequency domain bandwidth parameter of resource pools to match the capabilities and service requirements of different terminal types. By dynamically changing this key parameter based on terminal capability and service needs, the system achieves both high data rates for video monitoring and simplicity for IoT devices without requiring fundamentally different terminal architectures.
3Speed
If resource pool configuration is optimized for high bandwidth to meet video monitoring requirements, then data rate is improved, but power consumption increases
Solution Approach 1:
The patent applies local quality by matching resource pool bandwidth configuration to the specific capabilities and needs of individual terminal types. Redcap terminals receive resource pools configured within their bandwidth capability range, allowing them to operate at appropriate data rates without attempting to process bandwidths they cannot handle, thus avoiding unnecessary power consumption while still meeting their service requirements.
Solution Approach 2:
The patent implements partial action by configuring resource pools with bandwidths that are sufficient for the terminal's capability and service needs, rather than always providing maximum bandwidth. This partial configuration approach ensures that terminals operate within their efficient performance ranges, avoiding the excessive power consumption that would result from attempting to process beyond their capability limits while still achieving the required data rates for their applications.
