Solution Overview

Problem

Balancing transmission performance and power consumption in wireless transceiver devices with limited electrical energy is a challenge, especially when communicating with devices having different power capabilities.

Innovation Solution

A wireless transceiver device determines a suitable transmission mode by comparing modulation orders of incoming and outgoing data frames, selecting a mode from a frame transmission rate table that aligns with the lower of the two orders to ensure successful communication and reduce power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the data transmission rate is increased to improve transmission performance, then the transmission performance is improved, but the power consumption increases

Engineering Contradiction:
Improvetransmission performanceVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic transmission rate adjustment by comparing modulation orders of incoming and outgoing data frames. The transceiver device dynamically selects the appropriate transmission mode from a frame transmission rate table based on real-time modulation order comparison, allowing the system to adapt transmission performance and power consumption levels to actual communication needs rather than operating at a fixed high rate.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the transmission mode parameter based on modulation order parameters. By obtaining the first modulation order from the received data frame and comparing it with the second modulation order of the outgoing frame, the system selects a transmission mode that corresponds to the smaller modulation order, thereby adjusting the transmission rate parameter to balance performance and power consumption.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the transmission rate is set high for better performance, then transmission efficiency improves, but retransmissions occur when the receiving device cannot decode, increasing power consumption

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidcommunication reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent performs preliminary action by determining the appropriate transmission mode before actually transmitting the data frame. The processor compares modulation orders and selects the transmission mode in advance, ensuring that the transmitting device uses a rate that the receiving device can successfully decode, thereby preventing retransmissions before they occur.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses feedback from the received data frame's modulation order to adjust the transmission mode. By obtaining the first modulation order from the incoming frame and using it to determine the appropriate transmission mode for the outgoing frame, the system creates a feedback loop that ensures communication reliability while maintaining efficiency.

Inventive Principle:
Principle #23Feedback

AI summary

A wireless transceiver device includes a communication module and a processor. The communication module is used for receiving and demodulating a radio frequency signal from a wireless signal transmitting-receiving end into a first data frame. The processor is coupled to the communication module and used for performing the following operations: obtaining a first modulation order from the first data frame; determining a second modulation order corresponding to a second data frame that is to be transmitted by the wireless transceiver device; and determining a transmission mode from a frame transmission rate table according to a smaller one of the first modulation order and the second modulation order for the wireless transceiver device to send a response frame to the wireless signal transmitting-receiving end in response to the first data frame.
