Solution Overview

Problem

Existing transmitting/receiving devices in radio networks face inefficiencies in data transmission, particularly in ensuring successful data frame delivery and adapting to changing antenna conditions, leading to suboptimal performance and energy consumption.

Innovation Solution

A transmitting/receiving device monolithically integrated onto a semiconductor chip, equipped with a controller that switches between antennas based on acknowledgement messages and stores identification signals for optimal data frame transmission, allowing autonomous operation and energy conservation by switching to sleep mode.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If antenna switching is implemented to improve data transmission reliability, then the reliability of data frame delivery is improved, but the device complexity increases

Engineering Contradiction:
Improvedata frame delivery reliabilityVSAvoidantenna switching control complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The controller autonomously monitors acknowledgement messages and automatically switches between antennas without external intervention. The system self-manages the antenna switching process by evaluating received data frames and controlling the switching element based on internal criteria, eliminating the need for complex external control mechanisms.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback by monitoring acknowledgement messages from the receiving device and using this information to determine when to switch antennas. The controller receives feedback about transmission success or failure and adjusts antenna selection accordingly, creating a closed-loop control system that improves reliability while managing complexity through intelligent decision-making.

Inventive Principle:
Principle #23Feedback

2Productivity

If autonomous operation with intelligent antenna switching is implemented, then data transmission efficiency is improved, but the processing load on the controller increases

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoidcontroller processing load
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The controller performs partial automation by handling only the essential tasks of monitoring acknowledgement messages and making antenna switching decisions. Not all processing functions are automated - the controller selectively intervenes only when transmission issues arise, reducing overall processing load while maintaining sufficient autonomy for efficient operation.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The transmitting/receiving device performs self-service by automatically managing its own antenna switching based on simple criteria (presence of acknowledgement messages). This self-managed approach reduces the controller's processing burden compared to implementing complex autonomous decision-making algorithms, while still achieving improved data transmission efficiency.

Inventive Principle:
Principle #25Self-service

3Use of energy by moving object

If sleep mode is implemented to conserve energy, then energy consumption is reduced, but the response time for resuming transmission increases

Engineering Contradiction:
Improveenergy consumptionVSAvoidresponse time upon resumption
Core Design Contradiction:
Use of energy by moving objectVSLoss of time

Solution Approach 1:

The controller prepares for potential resumption by maintaining minimal operational state and pre-positioning antenna switching configurations. Before entering sleep mode, the system preserves essential transmission parameters and antenna state information, enabling rapid resumption without requiring full system reinitialization, thus reducing the time penalty associated with energy conservation.

Inventive Principle:
Principle #10Preliminary action

AI summary

In certain embodiments, an apparatus includes circuitry coupled to a switch between a first and second antenna of a device. The circuitry generates a first control signal for the switch to couple a transceiver of the device to the first antenna for transmission of a first data frame. The circuitry determines whether the transceiver has received, within a pre-determined time interval after transmission of the first data frame, a second data frame containing an acknowledgement message confirming successful receipt of the first data frame by another device. The circuitry generates, if the transceiver has not received the second data frame within the pre-determined time interval, a second control signal for the switch to couple the transceiver to the second antenna for re-transmission of the first data frame. An output line of the apparatus couples the circuitry to the switch and communicates the first or second control signal to the switch.
