Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The establishment of an NR-based PC5 connection between a remote terminal and a relay terminal in 5G networks is limited by the requirement for proprietary frequency bands, leading to increased development difficulty and prolonged development cycles.
Innovation Solution
Implementing a method for wireless communication that utilizes a non-3GPP access mode, such as WLAN or Bluetooth, to establish a direct communication connection between the remote and relay terminals, thereby reducing the need for proprietary frequency bands and simplifying the connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an NR-based PC5 connection is established between remote terminal and relay terminal using proprietary frequency bands, then reliable wireless communication is achieved, but development difficulty increases and development cycle is prolonged
Solution Approach 1:
The patent uses existing non-3GPP access networks (WLAN, Bluetooth) as intermediary communication channels between remote terminals and relay terminals. Instead of directly establishing NR-based PC5 connections requiring proprietary frequency bands, the system routes communications through these mature, standardized access networks, thereby reducing development complexity while maintaining communication reliability
Solution Approach 2:
The patent enables relay terminals to serve multiple functions by supporting both traditional 3GPP access and non-3GPP access modes. This multi-functionality allows the same relay terminal infrastructure to handle diverse communication scenarios using different access technologies, reducing the need for dedicated proprietary frequency band implementations and lowering overall system complexity
2Adaptability or versatility
If proprietary frequency bands are used for NR-based PC5 connection, then dedicated wireless communication is enabled, but commercial investment increases and development cycle is extended
Solution Approach 1:
The patent makes existing frequency bands and access networks serve multiple purposes by enabling them to carry both traditional 3GPP communications and non-3GPP relay communications. This universal utilization of existing spectrum resources eliminates the need for dedicated proprietary frequency bands while maintaining full wireless communication capability
Solution Approach 2:
The system leverages existing non-3GPP access networks (WLAN, Bluetooth) that already have their own frequency allocations and protocols to provide relay communication services. These networks essentially serve themselves by handling additional relay traffic without requiring external proprietary frequency band allocations, thereby reducing the quantity of frequency band resources needed
