Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in efficiently updating timing advance and power control parameters for user equipment (UE) moving in deterministic trajectories, leading to high signaling overhead and resource consumption.
Innovation Solution
Pre-configuring communication parameters such as timing advance and power control parameters as a function of time and location, allowing the network and UE to autonomously adjust settings without additional signaling, reducing the need for frequent updates and conserving resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequent updates of timing advance and power control parameters are performed through signaling, then communication reliability is improved, but signaling overhead and network resource consumption increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring timing advance and power control parameters before the UE actually needs them. The network provides a set of candidate parameters in advance, and the UE autonomously selects and applies the appropriate parameters based on its current location and trajectory, eliminating the need for frequent real-time signaling updates.
Solution Approach 2:
The patent implements self-service by enabling the UE to autonomously adjust its communication parameters without continuous network intervention. The UE uses its determined location and pre-configured parameter sets to automatically select optimal timing advance and power control values, reducing dependency on network signaling while maintaining communication reliability.
2Adaptability or versatility
If traditional parameter updating methods are used, then communication parameters can be adjusted in real-time, but power consumption and resource usage increase
Solution Approach 1:
The patent applies preliminary action by providing the UE with multiple candidate parameter sets in advance. These parameters are prepared beforehand based on predicted UE locations along its trajectory, allowing the UE to quickly switch between pre-configured parameters rather than continuously receiving update signals, thereby reducing power consumption while maintaining adaptability.
Solution Approach 2:
The patent implements parameter changes by organizing communication parameters into discrete, pre-configured sets that the UE can selectively apply. Instead of continuous parameter adjustment through frequent signaling, the UE transitions between predefined parameter sets based on its location, reducing the energy required for real-time parameter optimization.
3Quantity of substance
If autonomous parameter adjustment is implemented, then signaling overhead is reduced, but parameter configuration complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the parameter configuration into two distinct parts: (1) the network provides multiple candidate parameter sets with associated location information, and (2) the UE autonomously matches its current location to the appropriate parameter set. This segmentation reduces signaling overhead while managing complexity through clear division of responsibilities.
Solution Approach 2:
The patent uses location information as an intermediary that bridges the network and UE in the parameter adjustment process. The network provides parameters indexed by location, and the UE uses its determined location to select the appropriate parameters, eliminating the need for complex real-time negotiation while maintaining autonomous adaptation.
