Solution Overview

Problem

In wireless communication networks, autonomous uplink commands may not be reliably confirmed by the network, leading to issues such as data loss, excessive transmission delays, unfair spectrum occupancy, and inefficient battery usage due to missed or false detection of activation/deactivation commands.

Innovation Solution

Implementing an autonomous uplink confirmation mechanism where remote units send a confirmation message to the network upon receiving activation or deactivation commands, using a MAC control element or physical layer acknowledgement, to ensure accurate command reception.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If autonomous uplink commands are transmitted without confirmation, then transmission speed is improved, but reliability deteriorates due to undetected data loss

Engineering Contradiction:
Improvetransmission speedVSAvoidcommand reception reliability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The patent implements a confirmation feedback mechanism where the remote unit sends an autonomous uplink confirmation message back to the network unit after receiving and processing an autonomous uplink command. This feedback loop allows the network unit to verify whether the command was successfully received and executed, resolving the contradiction by maintaining high transmission speed while improving reliability through automated acknowledgment.

Inventive Principle:
Principle #23Feedback

2Reliability

If confirmation messages are transmitted for every autonomous uplink command, then reliability is improved, but spectrum efficiency deteriorates due to excessive transmissions

Engineering Contradiction:
Improvecommand reception reliabilityVSAvoidspectrum usage efficiency
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies partial action by implementing confirmation messages selectively rather than for every single command. The confirmation mechanism is triggered based on specific conditions such as command type, channel conditions, or network configuration, allowing the system to maintain reliability for critical commands while reducing unnecessary transmissions for less critical ones, thus optimizing spectrum efficiency.

Inventive Principle:
Principle #16Partial or excessive action

3Device complexity

If autonomous uplink operations are implemented without confirmation, then device complexity is reduced, but loss of information increases due to undetected command failures

Engineering Contradiction:
Improvecommunication protocol complexityVSAvoidcommand reception status
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent implements self-service by enabling the remote unit to autonomously generate and transmit confirmation messages without requiring complex external verification protocols. The confirmation mechanism is integrated into the autonomous uplink operation itself, allowing the system to maintain low complexity while preventing information loss through automated status reporting.

Inventive Principle:
Principle #25Self-service
