Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing V2X communication systems struggle to effectively manage communications between UEs with different types or capabilities, such as R14 and R15 V2X UEs, leading to inefficiencies and performance issues.
Innovation Solution
A method and device for determining a transmission mode by acquiring and utilizing service profile, access layer, and capability information to adapt the transmission mode to the receiving terminal, including selecting appropriate modulation, coding schemes, and data duplication methods based on UE capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unified transmission mode is used for all UEs in the system, then system complexity is reduced, but communication performance deteriorates when UEs have different capabilities
Solution Approach 1:
The patent applies local quality by determining transmission modes individually for each receiving UE based on its specific capability information. The transmitting UE acquires capability information about the receiving UE and selects transmission parameters (modulation scheme, coding rate, resource allocation) tailored to that specific UE's capabilities, rather than using a uniform transmission mode for all UEs. This resolves the contradiction by accepting increased local complexity to maintain high communication performance for each UE.
Solution Approach 2:
The patent implements dynamics by making the transmission mode adaptive and changeable based on the receiving UE's capability information. The transmitting UE dynamically adjusts transmission parameters according to the specific capabilities of different receiving UEs, allowing the system to optimize communication performance for each UE while managing complexity through structured capability-based adaptation.
2Reliability
If transmission modes are customized for each UE based on capability information, then communication performance is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by having UEs pre-report their capability information to the network and storing this information for future use. The transmitting UE retrieves previously acquired capability information about receiving UEs to determine appropriate transmission modes, avoiding the need for real-time capability negotiation and reducing the complexity of dynamic adaptation while maintaining optimized communication performance.
3Reliability
If advanced transmission features (64QAM, transmit diversity, carrier aggregation) are enabled for all UEs, then communication performance is maximized, but compatibility with older UEs is lost
Solution Approach 1:
The patent applies local quality by enabling advanced transmission features selectively for specific UEs based on their capability information. The transmitting UE determines which UEs support features like 64QAM, transmit diversity, and carrier aggregation, and applies these features only to compatible UEs. This resolves the contradiction by maintaining high communication performance for capable UEs while ensuring compatibility with older UEs that do not support these advanced features.

AI summary
Provided are a method and device for determining a transmission mode, a storage medium and an electronic device. The method includes acquiring information for determining the transmission mode, where the information includes at least one of: service profile information about a first service from an upper layer of a first terminal or an application layer of the first terminal, access layer information about the first terminal, transmission parameter information configured for the first terminal by a base station, or capability information about a second terminal of a proximity service; and determining the transmission mode according to the information. This can solve the problem in the existing art of how to perform communication better when there are UEs of different types or different capabilities in a system.
