Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-carrier positioning measurement scenarios, there is a time domain conflict between communication and positioning measurement on carriers in carrier aggregation (CA) and/or dual connectivity (DC), which affects data transmission and positioning accuracy.
Innovation Solution
A communication method where terminals and network devices exchange information on their capabilities for performing positioning measurements on multiple carriers, allowing for adaptive processing to resolve time conflicts by either simultaneous communication and measurement on different carriers or utilizing measurement gaps when capabilities are limited, ensuring effective data transmission and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multi-carrier positioning measurement is implemented to improve positioning accuracy, then positioning precision is improved, but time domain conflict with communication occurs
Solution Approach 1:
The patent segments the carrier resources into communication carriers and positioning measurement carriers, allowing them to operate independently. The terminal device is configured with a first set of carriers for communication and a second set of carriers for positioning measurement, which can be different carrier sets. This segmentation resolves the time domain conflict by separating the functions across different carriers.
Solution Approach 2:
The patent introduces carrier frequency dimension as an additional resource dimension to resolve the time domain conflict. By utilizing different frequency carriers for communication and positioning measurement, the system transforms the problem from a time resource contention into a frequency resource allocation problem, allowing simultaneous operation without interference.
2Productivity
If simultaneous communication and positioning measurement on multiple carriers is supported, then system capacity and positioning efficiency are improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic capability indication where the terminal device can flexibly indicate its support status for multi-carrier simultaneous communication and positioning measurement through capability information exchange with the network device. The system adapts to different terminal capabilities dynamically, allowing advanced terminals to utilize multi-carrier simultaneous operation while basic terminals use traditional sequential measurement, thus managing complexity adaptively.
Solution Approach 2:
The patent changes the operational parameters by introducing separate carrier set configurations (first set for communication, second set for positioning) and capability indication parameters. The network device configures different parameter sets based on terminal capability, allowing the system to optimize between performance and complexity through parameter adjustment rather than structural changes.
3Reliability
If measurement gaps are used to resolve time conflicts, then communication interruption is reduced, but measurement time increases
Solution Approach 1:
The patent segments the carrier usage such that positioning measurement can occur on dedicated carriers (second set) that are separate from communication carriers (first set). This eliminates the need for measurement gaps that would interrupt communication, as the terminal can simultaneously receive positioning reference signals on measurement carriers while maintaining communication on separate carriers, thus reducing both communication interruption and measurement time.

AI summary
The present disclosure relates to the technical field of wireless communications, and in particular to a communication method, an apparatus, and a readable storage medium. The method comprises: sending first information, the first information being used for indicating whether a terminal supports a first capability, and the first capability being the capability of performing positioning measurement on multiple carriers while communicating with a network device on the multiple carriers. In embodiments of the present disclosure, a terminal can send first information to report whether the terminal supports a first capability, so that according to different capabilities of the terminal, when there is a time conflict between communication and positioning measurement on multiple carriers, processing adapted to the capability of the terminal can be performed, thereby effectively solving the problem of time conflicts between different operations.
