Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems for augmented reality (AR), virtual reality (VR), and mixed reality (MR) devices face challenges in efficiently managing sidelink connections for carrier aggregation, particularly in environments with varying sub-carrier spacing values and channel bandwidths.
Innovation Solution
The method involves a first user equipment (UE) establishing a sidelink connection with a second UE and determining to operate in a carrier aggregation mode. The UE then operates the sidelink connection according to a set of predefined parameters, including sub-carrier spacing (SCS) values, resource block sizes, maximum transmission bandwidths, and minimum guardbands, to optimize communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If carrier aggregation mode is implemented with predefined parameters for sidelink communication, then communication efficiency and reliability are improved, but device complexity and parameter management overhead increase
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting sub-carrier spacing values and channel bandwidth configurations based on communication conditions. The system pre-determines multiple parameter sets including SCS values (15kHz, 30kHz, 60kHz) and channel bandwidths (5MHz, 10MHz, 20MHz, 40MHz), selecting appropriate combinations to optimize sidelink carrier aggregation performance while managing complexity through standardized parameter options.
2Adaptability or versatility
If multiple sub-carrier spacing values and channel bandwidths are supported, then adaptability to different communication environments is improved, but system complexity increases
Solution Approach 1:
The patent implements universality by designing a carrier aggregation system that can operate across multiple sub-carrier spacing values (15kHz, 30kHz, 60kHz) and channel bandwidth configurations (5MHz, 10MHz, 20MHz, 40MHz) within a unified framework. This multi-functional capability allows the same sidelink interface to adapt to diverse communication environments including pedestrian and vehicular scenarios without requiring separate specialized systems.
Solution Approach 2:
The system manages complexity through standardized parameter sets that can be pre-configured and selected based on communication conditions. By defining specific SCS values and channel bandwidth combinations, the patent reduces the complexity of handling multiple configurations while maintaining environmental adaptability.
3Productivity
If resource block sizes and guardbands are optimized according to SCS values, then communication efficiency is improved, but calculation and configuration complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-determining and storing optimal parameter combinations including resource block sizes and guardband configurations for different sub-carrier spacing values. This allows the system to quickly select pre-optimized configurations rather than calculating parameters in real-time, thereby improving communication efficiency while reducing the complexity of dynamic optimization.
