D2D Terminal Attribute Acquisition for Reliable Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
D2D communication methods face challenges in ensuring data transmission success rates due to lack of attribute information about participating terminals, leading to potential data receiving failures from excessive bandwidth or data block sizes.
Innovation Solution
A D2D communication method where a first terminal acquires attribute information of a second terminal, such as maximum bandwidth or antenna capabilities, to adjust communication parameters and perform data transmission accordingly, thereby increasing success rates without altering protocols significantly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If D2D communication is performed without network device scheduling, then communication autonomy and speed are improved, but data transmission success rate deteriorates due to lack of coordination
Solution Approach 1:
The patent applies preliminary action by having terminals acquire and store attribute information (bandwidth capabilities, antenna configurations, supported protocols) of neighboring terminals before actual D2D communication occurs. This pre-acquisition of capability data enables the transmitting terminal to adjust communication parameters in advance, preventing transmission failures without requiring network device scheduling during the actual communication.
2Productivity
If communication parameters are increased to improve data transmission capacity, then productivity is improved, but data receiving failures increase due to excessive bandwidth or data block sizes
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting communication parameters (bandwidth, data block size, modulation scheme) based on the acquired attribute information of the receiving terminal. The transmitting terminal modifies these parameters to match the receiving terminal's capabilities, ensuring optimal data transmission capacity while preventing receiving failures caused by excessive parameters.
3Reliability
If attribute information acquisition is implemented to improve transmission reliability, then data transmission success rate is improved, but device complexity increases due to additional information management requirements
Solution Approach 1:
The patent applies self-service by enabling terminals to autonomously acquire, store, and utilize attribute information of neighboring terminals without requiring network device intervention. The terminal independently manages the entire process of capability information acquisition and parameter adjustment, reducing overall system complexity while maintaining high transmission success rates.
