Uplink Power Control via Early Decoding Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power control mechanisms in UMTS systems fail to efficiently reduce unnecessary transmitting power consumption in terminals, leading to increased uplink interference and reduced system capacity and standby time, while maintaining required quality of service.
Innovation Solution
A power control method and device that determine whether to reduce the uplink channel transmitting power of a terminal based on data received during a Transmission Time Interval (TTI), allowing power reduction when specific conditions such as successful decoding of data or absence of uplink data transmission are met, and adjusting power levels accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal continuously transmits uplink channel data throughout the TTI, then the quality of service is ensured, but the transmitting power consumption increases unnecessarily
Solution Approach 1:
The base station performs preliminary decoding of uplink data before the TTI ends. When decoding succeeds early, the base station sends a power reduction command to the terminal, allowing the terminal to stop transmitting early. This preliminary action enables power savings without compromising service quality because the decoding is already complete.
Solution Approach 2:
The system implements a feedback mechanism where the base station monitors decoding progress and sends control commands to the terminal. When decoding succeeds, the base station feeds back a power reduction command, creating a closed-loop control system that dynamically adjusts terminal power based on actual decoding needs rather than continuous transmission.
2Reliability
If the terminal maintains high transmitting power throughout the TTI, then uplink service quality is maintained, but uplink interference increases
Solution Approach 1:
The base station performs preliminary decoding of uplink data before the TTI ends. When decoding succeeds early, the base station sends a power reduction command to the terminal, allowing the terminal to stop transmitting early. This preliminary action enables power savings without compromising service quality because the decoding is already complete.
Solution Approach 2:
The system implements a feedback mechanism where the base station monitors decoding progress and sends control commands to the terminal. When decoding succeeds, the base station feeds back a power reduction command, creating a closed-loop control system that dynamically adjusts terminal power based on actual decoding needs rather than continuous transmission.
3Reliability
If the terminal transmits throughout the entire TTI, then data transmission completeness is ensured, but standby time is reduced
Solution Approach 1:
The base station performs preliminary decoding of uplink data before the TTI ends. When decoding succeeds early, the base station sends a power reduction command to the terminal, allowing the terminal to stop transmitting early. This preliminary action enables power savings without compromising service quality because the decoding is already complete.
Solution Approach 2:
The system implements a feedback mechanism where the base station monitors decoding progress and sends control commands to the terminal. When decoding succeeds, the base station feeds back a power reduction command, creating a closed-loop control system that dynamically adjusts terminal power based on actual decoding needs rather than continuous transmission.

AI summary
The embodiment of the disclosure provides a power control method and device, a base station and a computer storage medium. The method includes: a first determination step of determining whether transmitting power of an uplink channel of a terminal is allowed to be reduced in subsequent slots of a current Transmission Time Interval (TTI) according to first data, received in a first part of slots of the TTI, of the uplink channel of the terminal at the end of the first part of slots of the current TTI, and if YES, entering a control step; and the control step of controlling the terminal to reduce the transmitting power of the uplink channel of the terminal before the end of a first slot in the subsequent slots.
