Solution Overview
Problem
User Equipment (UE) faces challenges in transmitting multiple pieces of data simultaneously in sidelink transmission due to limited processing capacity, resulting in data collisions.
Innovation Solution
A data processing method that determines first transmission priorities for overlapping time-domain resources and applies a target processing manner based on these priorities to manage and prioritize data transmission, preventing collisions and improving transmission performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UE transmits multiple pieces of data simultaneously in sidelink transmission, then the transmission capacity is improved, but the processing capacity limitation causes data collisions
Solution Approach 1:
The UE determines transmission priorities for multiple pieces of data before actual transmission occurs. This preliminary priority assignment enables the UE to pre-plan resource allocation and processing sequences, allowing simultaneous transmissions to be coordinated without collisions by establishing a predetermined handling order based on priority levels.
2Adaptability or versatility
If the UE determines transmission information for multiple pieces of data, then the transmission flexibility is improved, but the limited processing capacity prevents simultaneous transmission
Solution Approach 1:
The transmission process is segmented into distinct priority levels. Data pieces are divided into different priority groups, and the UE processes transmissions in a segmented manner according to these priority levels. This segmentation reduces the instantaneous processing burden by handling data in organized batches rather than requiring all data to be processed simultaneously with equal priority.
Solution Approach 2:
The UE changes the processing parameter of transmission priority for different data pieces. By assigning different priority parameters to different data pieces, the system transforms a complex simultaneous processing problem into a manageable sequential processing problem where the processing order is determined by the priority parameter values.
