Beam-Specific RMSI Transmission With Adaptive Parameters for 5G NR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, particularly 5G NR, face challenges in efficiently transmitting beam-specific remaining minimum system information (RMSI) due to varying channel conditions and coverage requirements, necessitating improved methods for system information transmission.
Innovation Solution
The base station transmits system information on different beams using varying parameters or content, and the UE receives scheduling information for beam-specific transmission parameters to adapt to these conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam-specific parameters are used for RMSI transmission, then coverage and signal quality are improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by transmitting RMSI with beam-specific parameters tailored to each beam's characteristics. Different beams use different transmission parameters (such as different time/frequency resources, modulation schemes, or coding rates) optimized for their specific channel conditions, thereby improving reliability without requiring complete system redesign.
Solution Approach 2:
The patent segments the RMSI transmission into multiple beam-specific transmissions. Instead of a single unified transmission, the system divides the coverage area into multiple beams, each carrying RMSI with parameters optimized for that specific beam's propagation conditions, allowing targeted optimization without increasing overall system complexity.
2Adaptability or versatility
If beam-specific transmission parameters are implemented, then adaptability to different channel conditions is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamics by making transmission parameters adaptive to beam-specific channel conditions. The system dynamically selects transmission parameters based on the characteristics of each beam, allowing the RMSI transmission to adapt to varying channel conditions such as path loss, interference, and mobility patterns specific to each beam direction.
Solution Approach 2:
The patent applies parameter changes by modifying transmission parameters (such as subcarrier spacing, cyclic prefix length, modulation order, or coding rate) based on beam-specific conditions. Each beam can use different parameter configurations optimized for its channel characteristics, enhancing adaptability without requiring fundamental system architecture changes.
