Adaptive Paging Bandwidth for Reliable RedCap Message Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paging mechanisms in wireless communication systems do not account for the varying bandwidth capabilities of user devices, particularly reduced capability devices like RedCap devices, leading to inefficient resource utilization and potential missed paging opportunities.
Innovation Solution
The system determines and utilizes the bandwidth supported by user devices, specifically RedCap devices, to transmit paging messages on a bandwidth compatible with the device capabilities, thereby optimizing paging configurations and ensuring message delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paging messages are transmitted using a standard bandwidth configuration, then the paging mechanism can support all user devices uniformly, but reduced capability devices like RedCap devices cannot receive paging messages effectively due to bandwidth mismatch
Solution Approach 1:
The patent implements dynamic bandwidth configuration for paging messages by introducing a bandwidth indication field in the paging message that specifies the bandwidth size. This allows the network to adaptively select appropriate bandwidth configurations (e.g., 5 MHz, 10 MHz, 20 MHz) based on the capabilities of target devices, enabling both full-capability and reduced-capability devices to receive paging messages reliably on compatible bandwidths.
Solution Approach 2:
The patent changes the bandwidth parameter of paging messages by incorporating a bandwidth indication field that explicitly specifies the bandwidth size used for transmitting the paging message. This parameter change enables the network to match the bandwidth of paging messages with the reception capabilities of different device types, ensuring reliable delivery to RedCap devices while maintaining compatibility with standard devices.
2Productivity
If the network transmits paging messages on wider bandwidth, then more data can be transmitted faster, but reduced capability devices consume more power and may miss paging opportunities
Solution Approach 1:
The patent applies local quality by transmitting paging messages with bandwidth configurations matched to specific device capabilities. Instead of using a uniform wide bandwidth for all devices, the network selectively uses narrower bandwidths (e.g., 5 MHz) for RedCap devices and wider bandwidths for standard devices, optimizing power consumption for each device type while maintaining paging transmission efficiency.
Solution Approach 2:
The patent implements dynamic bandwidth selection based on device capability assessment. The network determines the appropriate bandwidth configuration for each paging message based on the target device's capabilities, allowing efficient resource utilization by matching transmission parameters to device needs rather than using a fixed wide bandwidth for all transmissions.
3Device complexity
If the network uses a single paging configuration for all devices, then system complexity is reduced, but it cannot optimize paging for different device capabilities leading to missed opportunities
Solution Approach 1:
The patent achieves universality by designing a paging message structure that includes a bandwidth indication field capable of representing multiple bandwidth configurations. This single paging message format can serve both RedCap devices and standard devices by dynamically indicating the appropriate bandwidth, eliminating the need for separate paging configurations while maintaining optimization for different device types.
