Terminal Device Capability Reporting for Signaling Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face excessive signaling overheads when terminal devices report Maximum Sensitivity Degradation (MSD) improvement capabilities due to repeated reporting of similar band combinations, affecting downlink receiving performance.
Innovation Solution
The method involves reporting capability information by terminal devices in a manner that avoids redundant signaling by distinguishing between different band combinations and using filter conditions to target specific MSD improvement capabilities, reducing overheads through separate reporting of supported band combinations and MSD improvement capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal device reports MSD improvement capability for each band combination separately, then the network device can accurately determine UE capability, but the signaling overheads become excessively large
Solution Approach 1:
The patent segments the capability reporting into two distinct parts: band combination capability information and MSD improvement capability information. By separating these two types of information, the patent avoids redundant reporting while maintaining complete capability information. The MSD improvement capability is reported only once at the UE level rather than repeated for each band combination.
Solution Approach 2:
The patent makes the MSD improvement capability information universal by reporting it once at the UE level, which then applies to all band combinations. This single report serves multiple purposes - it provides MSD improvement information for every possible band combination without requiring separate reports for each one.
2Loss of energy
If the terminal device reports supported band combinations and MSD improvement capabilities separately, then signaling overheads are reduced, but the complexity of capability information structure increases
Solution Approach 1:
The patent divides the capability information structure into distinct segments: a first part for band combination capability information and a second part for MSD improvement capability information. This segmentation allows for clear separation of concerns while reducing overall complexity through structured organization.
Solution Approach 2:
The patent adds a dimensional distinction to the capability reporting by introducing separate fields for band combination information and MSD improvement information. This dimensional separation allows the network to efficiently process and interpret the capability information without redundancy.

AI summary
This application relates to the field of communication technologies, and provides a method for reporting capability information and an apparatus. The method includes: receiving first capability enquiry information from a network device; and reporting first capability information to the network device, where the first capability information indicates capability information of K band combinations supported by a terminal device and an MSD improvement capability of the terminal device for N band combinations, the N band combinations are combinations of bands in the K band combinations, K is a positive integer, and N is a positive integer. According to the method, signaling overheads for reporting the MSD improvement capability by the terminal device can be reduced.
