UE Capability Reporting for Contiguous Downlink Non-Contiguous Uplink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication technologies, user equipment (UE) supporting EUTRA-NR dual connectivity cannot effectively report its carrier aggregation capability when downlink carriers in the LTE and NR systems are contiguous but uplink carriers are non-contiguous, leading to inadequate resource allocation and compromised communication quality.
Innovation Solution
A method for reporting UE capability information that includes specific indication information to distinguish between contiguous and non-contiguous downlink and uplink carriers across different radio access technologies, enabling the network device to allocate appropriate communication resources based on the UE's carrier aggregation capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing UE capability information reporting methods are used, then the reporting process is simple, but the UE cannot report the capability when downlink carriers are contiguous and uplink carriers are non-contiguous
Solution Approach 1:
The capability reporting is segmented into multiple independent indication fields: first indication information for downlink carrier contiguity, second indication information for uplink carrier contiguity, and third indication information for cross-link carrier indication. This segmentation allows each aspect of carrier aggregation capability to be reported independently, enabling comprehensive reporting of mixed contiguous/non-contiguous scenarios.
Solution Approach 2:
The patent adds a new dimension to capability reporting by introducing separate indication fields for downlink and uplink carrier contiguity, and adding cross-link carrier indication. This multi-dimensional approach transforms the reporting from a single binary state to a comprehensive multi-state representation, allowing precise description of complex carrier aggregation capabilities.
2Productivity
If existing UE capability information reporting methods are used, then the signaling procedure is simple, but the network device cannot allocate appropriate communication resources
Solution Approach 1:
The capability information structure is segmented into distinct indication fields for different carrier aggregation aspects. This segmentation enables the network device to process and interpret each aspect independently, improving resource allocation efficiency by providing granular capability information without overwhelming complexity.
Solution Approach 2:
Different parts of the capability information structure serve specific local functions: first indication information handles downlink carrier contiguity, second indication information handles uplink carrier contiguity, and third indication information handles cross-link carrier indication. This local specialization allows the network device to allocate resources precisely according to each carrier aggregation characteristic.
3Reliability
If existing UE capability information reporting methods are used, then the implementation is straightforward, but the communication quality is compromised
Solution Approach 1:
The capability reporting mechanism is segmented into multiple precise indication fields that independently describe different aspects of carrier aggregation capability. This segmentation ensures that each aspect of communication quality requirements is explicitly reported, enabling the network device to make reliable resource allocation decisions based on comprehensive capability information.
Solution Approach 2:
The enhanced capability information structure provides detailed feedback to the network device about the UE's carrier aggregation capabilities. This comprehensive feedback mechanism enables the network device to understand the UE's precise capabilities and allocate resources accordingly, improving communication quality through informed decision-making.

AI summary
Embodiments of this application provide a method for reporting user equipment capability information and related device. A user equipment (UE) receives user equipment capability enquiry information sent by a network device, and reports the carrier aggregation capability of the user equipment by sending user equipment capability information to the network device, where the carrier aggregation capability of the user equipment includes the information that the downlink carriers of the UE in different radio access technologies are contiguous and the uplink carriers of the UE in the different radio access technologies are non-contiguous.
