UE Calibration Bandwidth Resource for Wireless Communication Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications systems, inconsistent understandings between base stations and user equipment (UE) about the operating bandwidth resource can lead to failed communication due to misconfiguration or incorrect feedback, resulting in data transmission failures.
Innovation Solution
The introduction of a UE calibration bandwidth resource for the base station to send information about the target operating bandwidth resource to the UE, and the implementation of a fallback mechanism to ensure consistent understanding of the operating bandwidth resource, allowing the UE and base station to recalibrate and maintain consistent configurations.

Engineering Contradiction Analysis
1Productivity
If the base station configures bandwidth resource for the UE, then the UE can operate within a manageable bandwidth subset, but inconsistent understandings between base station and UE about the operating bandwidth resource may occur
Solution Approach 1:
The patent applies preliminary action by introducing a calibration bandwidth resource before the actual bandwidth configuration takes effect. The base station sends indication information about the target operating bandwidth resource to the UE through this calibration resource, allowing the UE to prepare and confirm its understanding before the configuration becomes active. This prevents inconsistent understandings from occurring in the first place.
Solution Approach 2:
The patent implements feedback by requiring the UE to send feedback information regarding the target operating bandwidth resource received from the base station. The base station then determines whether the UE's understanding matches its own configuration intent. If there's a mismatch, the base station can send corrected indication information through the calibration bandwidth resource, ensuring both parties have consistent understanding before normal communication proceeds.
2Device complexity
If the base station and UE have inconsistent understandings about the operating bandwidth resource, then configuration errors may occur, but normal communication between base station and UE fails
Solution Approach 1:
The patent uses the calibration bandwidth resource as an intermediary channel for verifying bandwidth configuration understanding. Instead of directly activating the target operating bandwidth resource and risking communication failure, the system first uses the calibration resource to exchange indication information and feedback, acting as a safe intermediary step that prevents inconsistent configurations from causing communication breakdown.
Solution Approach 2:
The patent performs preliminary verification of bandwidth resource understanding through feedback exchange before the target operating bandwidth resource becomes active. The base station sends indication information through the calibration bandwidth resource, the UE provides feedback about its understanding, and the base station confirms consistency before switching to normal operation on the target resource.

AI summary
This application provides a bandwidth resource configuration method, an apparatus, and a system. The method includes: communicating, by a base station, first UE specific information of UE with the UE in a UE source operating bandwidth resource; and sending, by the base station, information about a UE target operating bandwidth resource of the UE to the UE in a UE calibration bandwidth resource of the UE, where the UE target operating bandwidth resource is used by the base station to communicate second UE specific information of the UE with the UE, and the UE source operating bandwidth resource is not completely the same as the UE calibration bandwidth resource. In the bandwidth resource configuration method provided in this application, calibration can be performed when the base station and the UE have inconsistent understandings about an operating bandwidth resource of the UE, and after the calibration, the base station and the UE can have consistent understandings about the operating bandwidth resource of the UE, thereby implementing normal communication between the base station and the UE.
