Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The mismatch in releases and capabilities between terminals and base stations in LTE networks leads to inefficient device functionality, resulting in decreased transmission efficiency and user experience due to ineffective cell reselection processes.
Innovation Solution
Configuring dedicated cell reselection parameter sets by base stations to match the capabilities of terminals, including parameters such as reselection priority, signal threshold, and signal threshold offset, to optimize cell reselection based on the intersection or mismatch of terminal and base station capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the base station supports advanced functions (carrier aggregation, 8×8 downlink MIMO), then the transmission rate and efficiency are improved, but the terminal cannot acquire the specific capability of the base station through system message, resulting in capability mismatch
Solution Approach 1:
The patent introduces a capability indicator as an intermediary element that bridges the terminal and base station. The base station broadcasts its capability indicator in system messages, and the terminal uses this indicator to determine whether to access the cell, thereby solving the information asymmetry problem without requiring the base station to explicitly broadcast detailed capability information.
Solution Approach 2:
The patent changes the parameter representation from detailed capability descriptions to a simplified capability indicator value. This parameter transformation allows the base station to convey its capability level (supporting advanced functions or not) in a compact form that can be efficiently broadcast in system messages, enabling terminals to make informed access decisions.
2Adaptability or versatility
If R11 terminals access R9 base stations or R9 terminals access R11 base stations, then network compatibility is maintained, but the device capability cannot function effectively due to release and capability mismatch
Solution Approach 1:
The patent segments the network into different capability levels by introducing capability indicators for base stations. Terminals can identify and select base stations with appropriate capability levels, ensuring that R11 terminals access R11 base stations for full functionality while R9 terminals access R9 base stations, thereby maintaining compatibility while optimizing capability utilization.
Solution Approach 2:
The patent enables dynamic capability matching between terminals and base stations. The terminal dynamically determines its access decision based on the broadcast capability indicator, allowing the system to adaptively optimize the matching between terminal capabilities and base station capabilities, thereby maximizing device functionality while maintaining network compatibility.
3Loss of information
If the base station broadcasts detailed capability information, then the terminal can make informed access decisions, but the system message complexity and overhead increase
Solution Approach 1:
The patent transforms detailed capability information into a simplified capability indicator parameter. Instead of broadcasting extensive capability descriptions, the base station broadcasts a compact indicator value that represents its capability level, significantly reducing system message complexity while maintaining sufficient information for terminal access decisions.
