Transceiver Data Transmission Control via Channel Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling data transmission in power-restricted applications, such as machine-type communications, face challenges in determining the required transmission power without a closed loop power control protocol, especially when no recent data transmission has occurred, leading to inefficient energy consumption and potential data loss.
Innovation Solution
A method that estimates the current required transmission effort based on received signals and historical statistics, using a time criterion to determine if data transmission should be initiated, allowing for dynamic decision-making and postponing transmission decisions to optimize energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmission power is increased to ensure reliable data delivery, then data transmission reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements dynamic transmission power adjustment based on real-time channel conditions. The transmitting unit determines current channel quality and selects transmission power adaptively, rather than using fixed high power. This dynamic approach ensures reliable transmission when needed while reducing power consumption during good channel conditions, directly resolving the contradiction between reliability and energy consumption.
Solution Approach 2:
The patent changes the transmission power parameter based on channel conditions and data priority. By adjusting this key parameter dynamically, the system achieves reliable transmission for high-priority data while using lower power for less critical transmissions, thereby resolving the contradiction between maintaining reliability and reducing overall energy consumption.
2Use of energy by moving object
If transmission power is reduced to save energy, then energy consumption is decreased, but data transmission reliability deteriorates
Solution Approach 1:
The patent applies different transmission power levels to different data packets based on their priority and channel conditions. High-priority data receives higher power for reliable transmission, while low-priority data uses lower power. This localized quality approach ensures critical transmissions are reliable while minimizing overall energy consumption, resolving the contradiction between power reduction and reliability maintenance.
Solution Approach 2:
The system dynamically adjusts transmission power based on real-time channel quality assessment. When channel conditions are good, lower power suffices for reliable transmission. When conditions deteriorate, power is increased only for necessary transmissions. This dynamic adaptation resolves the contradiction by matching power levels to actual transmission needs rather than using fixed conservative settings.
3Use of energy by moving object
If data transmission is delayed to wait for better channel conditions, then energy consumption is reduced, but transmission time increases
Solution Approach 1:
The transmitting unit performs preliminary assessment of channel conditions before initiating transmission. By evaluating channel quality in advance and preparing transmission strategies beforehand, the system can quickly decide whether to transmit immediately or wait, avoiding both unnecessary delays and wasteful high-power transmissions. This preliminary action resolves the contradiction between energy savings from waiting and time loss from delays.
Solution Approach 2:
The patent implements dynamic decision-making for transmission timing based on real-time channel conditions and data priority. The system continuously monitors channel quality and adjusts transmission timing dynamically - transmitting immediately for high-priority data regardless of conditions, or waiting for better conditions for low-priority data. This dynamic timing strategy resolves the contradiction between energy consumption and transmission time by adapting to actual system needs.
4Measurement precision
If closed loop power control protocol is used to determine transmission power, then transmission power accuracy is improved, but system complexity increases
Solution Approach 1:
The transmitting unit autonomously determines transmission power by assessing channel conditions itself, without requiring external control signals from a base station. The system uses its own measurements and internal logic to make power decisions, eliminating the need for complex closed-loop protocols while maintaining accurate power determination. This self-service approach resolves the contradiction between accuracy and complexity.
Solution Approach 2:
The patent extracts the essential function of power control from the complex closed-loop protocol framework. Instead of implementing the full protocol suite, the system takes out only the critical power determination function and implements it through simplified channel quality assessment and internal decision logic. This extraction maintains transmission power accuracy while significantly reducing system complexity.

AI summary
A method of controlling data transmission of a transceiver is disclosed. The method comprises determining that data is pending for transmission by the transceiver and receiving a signal. A current required transmission effort for transmission of the data is estimated based on the received signal and it is determined if data transmission is to be initiated based on the estimated current required transmission effort, required transmission effort statistics and a time criterion associated with the data. Transmission of the data is initiated if it is determined that so should be done and otherwise the decision of transmitting the data is postponed. Corresponding computer program product, processor, arrangement and wireless communication device are also disclosed.
