Relay State Reporting for Wireless Terminal Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially in public safety networks, there is a need for an efficient method to report the state of a relay function performed by terminals, as current systems may unnecessarily activate relay operations, leading to interference and inefficient resource usage due to lack of knowledge about nearby terminals providing relay functions.
Innovation Solution
A method and apparatus for a user equipment (UE) to detect the state of a relay function and transmit a report to a second network node, allowing the network to accurately instruct relay operations and optimize resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network instructs terminals to activate relay function without knowing the state of nearby terminals, then relay operations can be activated, but unnecessary relay activation occurs causing interference and inefficient resource usage
Solution Approach 1:
The patent implements a feedback mechanism where terminals report their relay function states to the network. The network receives relay state information from terminals and uses this feedback to make informed decisions about relay activation, preventing unnecessary relay operations and avoiding interference with existing relay terminals.
Solution Approach 2:
The patent introduces relay state information as an intermediary element between the network and relay activation decisions. This information acts as a mediator that enables the network to understand the current relay landscape before making activation decisions, thus avoiding conflicts and inefficient resource allocation.
2Area of stationary object
If the network activates relay function without information about nearby relay terminals, then relay coverage can be extended, but interference is caused to other terminals providing relay function
Solution Approach 1:
The network receives feedback information about the relay states of nearby terminals before making relay activation decisions. This feedback mechanism allows the network to identify areas where relay functions are already active, preventing activation of additional relays that would cause interference and enabling intelligent expansion of coverage areas.
3Productivity
If relay function state reporting is implemented, then resource allocation can be optimized, but additional signaling overhead is introduced
Solution Approach 1:
The patent extracts only the essential relay state information that is necessary for network decision-making, rather than reporting all possible terminal parameters. This selective extraction approach provides sufficient information for optimizing relay activation and resource allocation while minimizing signaling overhead.
