Base Station Band Switching for High-Power Terminal Uplink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminals configured with high power transmission capabilities often connect to cells that are not applicable for high power transmission, leading to underutilization of their capabilities.
Innovation Solution
A method to determine if a terminal is configured with high power transmission class but not operating in an applicable band, and if so, to switch it to a high power transmission applicable band based on channel quality evaluation and access priority, using a base station to send switching control instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal selects a cell with the best connection signal strength during cell selecting, then the connection quality is improved, but the high power transmission capability cannot be fully utilized when the selected band is not applicable for high power transmission
Solution Approach 1:
The base station performs preliminary assessment of terminal capabilities and current band applicability before the terminal makes cell selection decisions. The base station evaluates whether the terminal supports high power transmission and whether the current band is applicable, then provides guidance information to the terminal in advance, allowing the terminal to adjust its cell selection strategy proactively rather than reactively
Solution Approach 2:
The base station receives capability information from the terminal regarding high power transmission support, evaluates the current band applicability, and provides feedback guidance information to the terminal. This feedback loop enables the terminal to understand whether it should prioritize connection quality or high power transmission capability utilization when selecting cells
2Stability of the object's composition
If the terminal operates in a band that provides good signal strength, then the connection stability is improved, but the transmission power cannot be increased when the band is not applicable for high power transmission
Solution Approach 1:
The system dynamically adjusts the terminal's operating parameters based on real-time conditions. The base station evaluates both the stability benefits of the current band and the power transmission opportunities, then provides dynamic guidance information that allows the terminal to adapt its transmission strategy according to whether the current band supports high power transmission
3Reliability
If the terminal uses high power transmission in all bands, then the uplink performance is improved, but the power consumption increases and battery life decreases
Solution Approach 1:
The system applies high power transmission selectively rather than uniformly across all bands. The base station evaluates the local characteristics of each band to determine whether it supports high power transmission, and provides targeted guidance information only for bands where high power transmission is both supported and beneficial, allowing the terminal to maintain low power consumption in bands where it is unnecessary
