Terminal Device Conflict Resolution Using Dynamic Priority Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for resolving conflicts between uplink and sidelink transmission in terminal devices, as defined in Release 14, fail to meet the data transmission requirements of Release 15 and subsequent releases, as they rely on a preconfigured ProSe per-packet priority threshold to prioritize transmissions, leading to inefficiencies in power allocation and data discard decisions.
Innovation Solution
A conflict resolving method for terminal devices that determines, based on the ProSe per-packet priority of sidelink data and a preset or dynamically configured limit, whether to preferentially transmit sidelink or uplink data on multiple carriers, ensuring data transmission conflicts are resolved by optimizing power allocation and transmission priorities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a preconfigured PPPP threshold is used to resolve transmission conflicts, then the terminal device can make simple priority-based decisions, but the data transmission efficiency and power allocation optimization are insufficient for Release 15 and subsequent releases
Solution Approach 1:
The patent transforms the static preconfigured threshold into a dynamic limit that can be adjusted based on actual transmission conditions. The terminal device determines whether to transmit sidelink or uplink data by comparing PPPP values against a dynamic limit rather than a fixed threshold, enabling adaptive priority management that improves transmission efficiency while maintaining operational simplicity
Solution Approach 2:
The patent changes the parameter from a fixed threshold to a dynamic limit that can vary based on transmission conditions. By allowing the limit to be adjusted rather than predetermined, the system can optimize power allocation and transmission efficiency for different scenarios in Release 15 and beyond
2Device complexity
If the terminal device discards uplink or sidelink data based on a fixed threshold, then the conflict resolution is straightforward, but the power allocation cannot be optimized for different transmission scenarios
Solution Approach 1:
The patent introduces dynamic adjustment capability to the conflict resolution mechanism. Instead of using a fixed threshold that leads to straightforward but suboptimal decisions, the system employs a dynamic limit that adapts to transmission conditions, enabling optimized power allocation while keeping the decision-making process relatively simple
Solution Approach 2:
The patent implements feedback mechanisms where the terminal device monitors transmission conditions and adjusts the limit accordingly. This feedback loop enables the system to learn from actual transmission scenarios and optimize power allocation dynamically, improving energy efficiency while maintaining manageable complexity
3Ease of manufacture
If the terminal device uses a fixed PPPP threshold for priority comparison, then the implementation is simple, but it cannot satisfy the enhanced data transmission requirements of Release 15 and subsequent releases
Solution Approach 1:
The patent transitions from a static fixed threshold implementation to a dynamic limit-based system. This dynamic approach maintains implementation simplicity while significantly improving the system's ability to satisfy enhanced data transmission requirements in Release 15 and subsequent releases through adaptive priority management
Solution Approach 2:
The patent creates a universal conflict resolution mechanism that can handle multiple transmission scenarios and requirements. By using a dynamic limit rather than a fixed threshold, the system becomes multi-functional, capable of adapting to different transmission conditions and satisfying diverse data transmission requirements while maintaining a unified implementation approach

AI summary
Embodiments of this application provide a conflict resolving method and a terminal device. When uplink transmission conflicts with sidelink transmission in time, the terminal device can resolve the data transmission conflict based on a ProSe per-packet priority (PPPP) of data on a sidelink and a limit, thereby satisfying data transmission requirements in Release 15 and subsequent Releases. The method is applied to terminal-to-terminal communication. A terminal device needs to transmit sidelink data on M first-type carriers and transmit uplink data on N second-type carriers, and M and N are positive integers. The method includes: determining, by the terminal device based on a PPPP of the sidelink data transmitted on the M first-type carriers and a first limit, to preferentially transmit the sidelink data on some or all of the M first-type carriers, or to preferentially transmit the uplink data on some or all of the N second-type carriers.
