User Equipment Sidelink Resource Reporting Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high frequency band D2D communication, the overhead for reporting resources for transmitting synchronization signals and broadcast information is increased when different beams are used for different resources.
Innovation Solution
The solution involves reducing the overhead for reporting resources by using a shared resource for transmitting synchronization signals and broadcast information, allowing user equipment to transmit these signals using a resource already allocated for DL or UL.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different beams are used for different resources to transmit synchronization signals and broadcast information in high frequency band D2D communication, then the coverage and reliability are improved, but the overhead for reporting resources is increased
Solution Approach 1:
The patent applies universality by allowing a single beam to serve multiple functions: it transmits both synchronization signals and broadcast information across multiple resources. Instead of dedicating different beams to different resources, one beam is universally used for multiple purposes, reducing the resource reporting overhead while maintaining reliable communication in high frequency band D2D scenarios
2Stability of the object's composition
If multiple resources are allocated for transmitting synchronization signals and broadcast information with different beams, then the transmission robustness is improved, but the device complexity is increased
Solution Approach 1:
The patent merges the transmission of synchronization signals and broadcast information into a single beam resource. By combining multiple functions into one beam instead of using separate beams for each resource, the system reduces beam resource management complexity while maintaining transmission robustness through repeated use of the same beam configuration
