Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face challenges in managing uplink duty cycles to comply with electromagnetic radiation safety standards, particularly in Frequency Division Duplexing (FDD) scenarios, leading to increased complexity and power consumption due to continuous monitoring by terminals.
Innovation Solution
A method and apparatus that involve a base station controlling uplink resources within a target time window based on terminal capability information, allowing terminals to stop monitoring duty cycles and reducing electromagnetic radiation by selectively managing uplink resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal continuously monitors the uplink duty cycle to ensure compliance with electromagnetic radiation safety standards, then the safety requirement is met, but the device complexity and power consumption increase
Solution Approach 1:
The patent extracts the duty cycle monitoring function from the terminal and transfers it to the base station. The base station calculates and controls the uplink duty cycle based on terminal capability information, while the terminal simply needs to receive indication information and stop monitoring. This division of labor reduces terminal complexity while maintaining safety compliance.
Solution Approach 2:
The patent implements a feedback mechanism where the terminal reports its maximum duty cycle capability information to the base station, and the base station uses this feedback to configure appropriate uplink resources. The base station then sends indication information back to the terminal to confirm the control policy is active. This closed-loop feedback ensures safety compliance without requiring continuous terminal monitoring.
2Reliability
If the terminal continuously monitors the uplink duty cycle, then electromagnetic radiation safety is ensured, but power consumption increases
Solution Approach 1:
The patent extracts the power-intensive duty cycle monitoring and calculation function from the terminal and relocates it to the base station. The terminal only performs low-power operations of receiving indication information and stopping monitoring, thereby significantly reducing power consumption while maintaining safety compliance through base station-controlled duty cycle management.
3Object-affected harmful factors
If the base station controls uplink resources according to terminal capability information, then electromagnetic radiation exposure is reduced, but the device complexity at the base station increases
Solution Approach 1:
The patent applies preliminary action by having the terminal report its maximum duty cycle capability information to the base station in advance. The base station then pre-calculates appropriate uplink resource configurations and sends indication information to the terminal before actual communication occurs. This advance preparation simplifies real-time control while reducing electromagnetic radiation exposure.
