Terminal Capability Bitmap Reporting for Multiple NS Values
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing radio communication systems, User Equipment (UE) is unable to report a supported Network Signaling (NS) value when multiple NS values are defined in a frequency band, hindering the network's ability to obtain a detailed report on terminal capability.
Innovation Solution
The UE is configured to report terminal capability by using a bitmap to indicate the corresponding NS value for modified spectrum emission, allowing the network to obtain a detailed report on terminal capability through the inclusion of 'modifiedMPR-Behavior' and 'SupportedAdditionalSpectrumEmission' information elements in the UE capability report.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a bitmap is used to indicate the corresponding NS value for modified spectrum emission, then the network can obtain a detailed report on terminal capability, but the device complexity increases due to the need to process and interpret bitmap information
Solution Approach 1:
The patent uses a bitmap as a simplified representation (copy) of terminal capability information. Instead of transmitting detailed capability descriptions, the system creates a compact bitmap copy that efficiently encodes which NS values are supported, reducing information loss while maintaining manageable processing complexity.
Solution Approach 2:
The patent transforms terminal capability information into a different parameter format - specifically, converting capability data into bitmap values where each bit position represents a specific NS value. This parameter transformation enables efficient encoding and decoding of capability information, resolving the contradiction between information completeness and processing complexity.
2Adaptability or versatility
If multiple NS values are defined in a frequency band, then the system supports more spectrum emission configurations, but the UE is unable to report a supported NS value to a network
Solution Approach 1:
The patent introduces a new dimension for representing NS value support - the bitmap dimension. By mapping NS value support to bit positions in a bitmap structure, the system enables the UE to report supported values even when multiple NS values are defined, transforming the reporting mechanism into a higher-dimensional solution space.
Solution Approach 2:
The bitmap acts as an intermediary between the UE's internal capability state and the network's interpretation. This intermediate representation structure enables the UE to convey supported NS values indirectly through bitmap patterns, resolving the information loss problem while maintaining adaptability to multiple NS value configurations.

AI summary
A terminal includes a receiving unit that receives, from a base station, information for requesting a report on terminal capability; a control unit that includes, when a plurality of values indicating respective additional spectrum emissions is defined for a frequency band, first information indicating modifications on spectrum emissions corresponding to the respective plurality of values indicating the respective additional spectrum emissions in the report, as the terminal capability; and a transmitting unit that transmits the report to the base station.
