Remote Terminal Parameter Configuration via Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The introduction of sidelink relays in communication systems has created a need for configuring parameters in new scenarios where devices are outside network coverage and in various RRC states, which existing methods cannot effectively address.
Innovation Solution
A parameter configuration method that determines the appropriate parameters for remote terminals based on network coverage status and RRC states, allowing for preconfigured, SIB-broadcasted, or RRC-signaling-configured parameters, and decides on parameter forwarding or sending by relay and network devices accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sidelink relays are introduced to enable communication for remote terminals, then communication coverage is extended, but parameter configuration complexity increases
Solution Approach 1:
The patent implements dynamic parameter configuration by determining different parameter sets based on the remote terminal's RRC state (idle, inactive, or connected) and network coverage status. The relay terminal dynamically selects and forwards appropriate parameters from different sources (pre-configured, SIB, or RRC signaling) depending on the current system state, making the configuration process adaptive rather than static.
Solution Approach 2:
The relay terminal serves as an intermediary that bridges the network device and remote terminal. It receives parameters from the network device and selectively forwards them to the remote terminal based on the remote terminal's state. This intermediary approach simplifies the overall system by centralizing the parameter selection logic at the relay terminal rather than requiring complex direct configuration between network devices and remote terminals.
2Reliability
If parameters are configured based on RRC state and network coverage, then communication reliability is improved, but configuration time increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring parameters at the relay terminal before actual communication begins. The relay terminal stores multiple parameter sets (pre-configured parameters, SIB parameters, and RRC signaling parameters) in advance and selects the appropriate ones based on the remote terminal's state during the configuration process, eliminating the need for real-time parameter generation and reducing configuration time.
3Productivity
If relay terminals forward parameters for remote terminals, then communication efficiency is improved, but energy consumption increases
Solution Approach 1:
The patent implements partial action by having relay terminals selectively forward only the necessary parameters based on the remote terminal's RRC state and network coverage status. Instead of forwarding all possible parameters unconditionally, the system determines the minimal required parameter set for each scenario, reducing unnecessary data transmission and associated energy consumption while maintaining communication efficiency.
