Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power control mechanisms in 3GPP wireless communications systems do not adequately conserve battery life in Machine-Type Communications (MTC) devices experiencing varying signal conditions due to mobility or signal attenuation changes.
Innovation Solution
A communications device that delays data transmission until radio signal quality meets a predetermined criteria, allowing for lower power consumption by transmitting data when signal conditions improve, and includes features for monitoring and adjusting transmission delays based on changing signal quality and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If data transmission is delayed until radio signal quality meets predetermined criteria, then battery life is prolonged and power consumption is reduced, but transmission latency increases
Solution Approach 1:
The communications device performs preliminary assessment of radio signal quality before initiating data transmission. By evaluating signal conditions in advance and only transmitting when criteria are met, the device avoids unnecessary retransmissions and optimizes power usage, thereby prolonging battery life while managing transmission latency through proactive decision-making
Solution Approach 2:
The transmission delay is made dynamic rather than fixed. The device continuously monitors radio signal quality and adjusts the transmission timing based on real-time conditions. This dynamic approach allows the system to balance battery conservation with latency requirements by transmitting as soon as signal conditions are favorable, rather than using a predetermined static delay
2Loss of energy
If data transmission is delayed until radio signal quality meets predetermined criteria, then power consumption and co-channel interference are reduced, but transmission speed decreases
Solution Approach 1:
The device implements a feedback mechanism by continuously monitoring radio signal quality metrics and using this information to make informed transmission decisions. This feedback loop ensures that data is transmitted only when signal conditions indicate successful delivery is likely, reducing power consumption and avoiding retransmissions, while maintaining transmission speed through responsive adaptation to channel conditions
3Reliability
If existing power control mechanisms are used, then signal quality is maintained, but battery life is not adequately conserved in MTC devices with varying signal conditions
Solution Approach 1:
The invention applies local quality assessment by evaluating radio signal quality specifically at the moment of potential transmission initiation. Rather than using uniform power control across all conditions, the device adapts its transmission behavior to local signal conditions, transmitting only when quality criteria are met. This localized approach maintains signal quality reliability while significantly improving battery life conservation for MTC devices experiencing varying signal conditions

AI summary
A system is disclosed in which a communications device communicates via a cell operated by a base station of a communications network. The communications device identifies that transmission of data to a communications node coupled to the communications network has been triggered; determines whether an indication of radio quality in the cell meets a required radio quality criteria responsive to the transmission being triggered. The transmitting element transmits the data to the communications network after a delay if the quality of radio signals does not meet the required radio quality criteria, and without the delay if the quality of radio signals meets the required radio quality criteria.
