UE MSD Region Reporting for Smarter Frequency Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems fail to differentiate between user equipment (UEs) with varying maximum sensitivity degradation (MSD) values, leading to inefficient resource allocation and underutilization of UEs with lower MSD, as networks treat all UEs uniformly, thus discouraging improved UE development.
Innovation Solution
User equipment (UE) indicates specific frequency regions within a victim frequency band where MSD is zero or low, allowing networks to optimize resource allocation and scheduling based on these regions, thereby enabling more efficient use of frequency resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If networks treat all user equipment uniformly, then implementation is simplified, but resource allocation efficiency deteriorates and UEs with lower MSD are underutilized
Solution Approach 1:
The patent segments the victim frequency band into multiple regions based on MSD characteristics. The network node identifies and reports specific frequency regions where the UE exhibits low or zero MSD, allowing differentiated treatment of frequency resources rather than uniform treatment across the entire band.
Solution Approach 2:
The patent applies local quality by assigning different quality levels to different frequency regions. Frequency regions with low/zero MSD are identified and marked as having higher quality, enabling the network to preferentially allocate resources in these regions to UEs with corresponding MSD characteristics, thereby optimizing overall system performance.
2Productivity
If networks optimize resource allocation based on MSD regions, then resource allocation efficiency improves, but implementation complexity increases
Solution Approach 1:
The patent implements preliminary action by having the network node pre-calculate and store MSD values for different frequency regions before actual resource allocation. The MSD region information is reported and cached in advance, so when resource allocation decisions need to be made, the network can quickly reference pre-computed MSD region data without performing complex real-time calculations.
3Productivity
If UE MSD characteristics are differentiated, then resource utilization improves, but measurement and detection difficulty increases
Solution Approach 1:
The patent applies self-service by having the UE autonomously measure its own MSD characteristics across different frequency regions and report this information to the network. The UE performs self-testing and self-characterization, eliminating the need for complex network-side measurement apparatus and simplifying the overall detection process.

AI summary
Techniques of wireless communications include enabling the UE to indicate region in the channel bandwidth of a band combination where the MSD is zero or small. The indication defines a frequency boundary where MSD is “low” (e.g., small or zero dB) and MSD is “high” (e.g., >0 dB), and may contain a frequency offset from the centre of the MSD originating source to the boundary. The UE indication may be given as part of UE capabilities (e.g., UE indicates per BC the MSD region and MSD value within the region), or as a part of UE response to a network request (e.g., network requests UE to report MSD values for a given band combination and UE provides the information), with a UE capability for supporting such request-response mechanism.
