Beam Measurement Feedback for Wireless Access Mode Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network devices struggle to determine an optimal access manner for terminals due to coverage holes and changing transmission environments, leading to inefficiencies in communication quality.
Innovation Solution
Terminals measure and report beam-specific information, such as signal quality and channel correlation, to network devices, enabling them to determine the most effective access method, whether direct or through a first node like a large intelligent surface, thereby improving communication quality and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network device uses multiple access manners (direct access and relay access through first node) to improve communication coverage and quality, then the communication reliability is improved, but the device complexity increases due to the need to determine and manage multiple access paths
Solution Approach 1:
The terminal feeds back channel quality information and beam measurement results to the network device. The network device uses this feedback to determine the optimal access manner (direct or relay) dynamically, resolving the contradiction by using information-driven decision making rather than complex manual configuration
Solution Approach 2:
The terminal autonomously measures beam qualities and prepares access state information, then reports it to the network device. This self-service approach reduces the network device's complexity while maintaining reliable multi-path access capability
2Productivity
If the terminal reports detailed beam measurement information to enable accurate access manner determination, then the productivity is improved through optimal resource allocation, but the loss of energy increases due to additional uplink transmission
Solution Approach 1:
The terminal extracts only the most critical beam measurement information (channel quality, access state) needed for access manner determination and reports only that. This selective reporting reduces uplink energy consumption while providing sufficient information for the network device to make optimal resource allocation decisions
Solution Approach 2:
The terminal changes the parameter of reported information from comprehensive beam data to condensed access state information. This parameter transformation reduces the volume of uplink transmission, lowering power consumption while maintaining the ability to determine optimal access manners
