Terminal Capability Indication for Out-of-Band Cell Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal devices may experience cell access failures due to not supporting newly defined additional out-of-band radiation requirements, leading to configuration issues in multi-network coexistence scenarios.
Innovation Solution
The terminal device sends indication information to the network device to inform it of the additional out-of-band radiation requirements it supports, allowing the network device to configure accessible cells accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network device configures cells based on newly defined additional out-of-band radiation requirements, then the out-of-band radiation requirement is improved, but terminal devices that do not support these requirements experience cell access failure
Solution Approach 1:
The terminal device proactively reports its supported additional out-of-band radiation requirements to the network device before cell configuration. This preliminary capability indication allows the network device to pre-determine compatible cells and avoid configuration failures, resolving the contradiction by enabling future-proof network configuration while maintaining backward compatibility with older terminals.
2Measurement precision
If the terminal device reports additional out-of-band radiation requirement capabilities, then cell configuration accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent defines specific parameter formats for capability reporting, including bitmap indicators and enumerated values, to efficiently represent additional out-of-band radiation requirement support. By standardizing these parameter representations, the system achieves precise capability indication with minimized signaling overhead, resolving the contradiction between measurement precision and information loss.

AI summary
An information indicating method, apparatus, device and storage medium, which relates to the field of communication. The method includes: sending, by a terminal device, indication information to a network device, where the indication information is used to indicate an additional out-of-band radiation requirement supported by the terminal device (402). By sending the indication information from the terminal device to the network device, the network device can determine the additional out-of-band radiation requirement supported by the terminal device, so as to configure a reasonable cell to the terminal device, and avoid a problem of a cell access failure when the terminal device does not support the additional out-of-band radiation requirement.
