Repeater Forwarding Direction via TDD Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently configuring the forwarding direction for repeaters, particularly in millimeter wave networks, leading to resource wastage and increased costs due to the need for frequent beam training and management.
Innovation Solution
The method involves determining the forwarding direction for repeaters based on Time Division Duplexing (TDD) information, allowing repeaters to selectively forward signals without explicit configuration from base stations, thereby reducing signaling overhead and improving resource usage efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If explicit forwarding direction indications are provided from base station to repeater, then the repeater can correctly forward signals, but signaling overhead increases and resource consumption increases
Solution Approach 1:
The repeater autonomously determines the forwarding direction for resources by checking whether the resource is configured for uplink or downlink transmission, without requiring explicit forwarding direction indications from the base station. This self-service mechanism reduces signaling overhead while maintaining correct signal forwarding.
Solution Approach 2:
The system pre-configures resources with uplink or downlink directions before actual signal transmission. The repeater uses these pre-configured directions to determine forwarding behavior, eliminating the need for real-time explicit forwarding indications and reducing signaling overhead.
2Reliability
If frequent beam training and management are performed for repeater configuration, then signal quality is maintained, but resource wastage increases and costs increase
Solution Approach 1:
The repeater autonomously adapts its forwarding behavior based on pre-configured resource directions, eliminating the need for frequent base station interventions and beam training. This self-service approach maintains signal quality while significantly reducing resource wastage associated with frequent configuration updates.
Solution Approach 2:
Instead of frequent continuous beam training and management, the system uses periodic pre-configured resource directions that remain valid for multiple transmission instances. This periodic configuration approach reduces the frequency of beam training operations while maintaining adequate signal quality.
3Reliability
If explicit configuration information is transmitted to repeater for each resource, then forwarding accuracy is improved, but device complexity and processing overhead increase
Solution Approach 1:
The repeater uses a simple self-service mechanism where it autonomously determines forwarding direction by checking pre-configured resource directions against the current resource being processed. This eliminates the need for complex processing of explicit configuration information for each resource while maintaining forwarding accuracy.
Solution Approach 2:
The base station performs the complex configuration work in advance by pre-configuring resource directions. The repeater then simply references these pre-configured directions during operation, significantly reducing the device complexity and processing overhead during actual signal forwarding.
