Terminal Transmitter State Feedback for Multi-Band Uplink Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in determining the transmitter state of a terminal when its transmitter chains dynamically switch among multiple uplink bands, leading to ambiguity and potential interruptions in uplink transmission.
Innovation Solution
A method and system for determining the transmitter state by sending configuration information to the terminal, allowing dynamic switching among more than two bands, and specifying the transmitter state in cases of ambiguity to ensure proper band switching and minimize transmission interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dynamic band switching among more than two bands is implemented to improve uplink data rate and capacity, then uplink performance is improved, but transmitter state determination becomes ambiguous and transmission interruptions occur
Solution Approach 1:
The base station sends transmitter state configuration information to the terminal, creating a feedback mechanism that resolves ambiguity in transmitter state determination. This information flow from base station to terminal ensures both parties have consistent knowledge of the transmitter state, eliminating transmission interruptions while maintaining dynamic band switching capability for improved uplink performance
2Productivity
If dynamic band switching among more than two bands is implemented to improve spectrum utilization, then spectrum efficiency is improved, but transmitter state determination becomes ambiguous
Solution Approach 1:
The transmitter state configuration information acts as feedback that eliminates information loss about transmitter state. By systematically conveying state configuration from the base station to the terminal, the system maintains complete information awareness throughout the dynamic band switching process, enabling improved spectrum utilization without ambiguity
3Reliability
If transmitter state configuration information is sent to resolve ambiguity, then transmission continuity is improved, but system complexity increases
Solution Approach 1:
The base station performs preliminary action by sending transmitter state configuration information before band switching occurs. This advance configuration resolves potential ambiguities before they cause transmission interruptions, improving reliability while the structured nature of the configuration information keeps the added complexity manageable
