Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If data is transmitted using frequent PA ON/OFF transitions to handle varying traffic demands, then network adaptability is improved, but energy consumption increases

Engineering Contradiction:

Improvenetwork adaptabilityVSAvoidenergy consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent merges multiple noncontiguous transmission timeslots into contiguous blocks, allowing the power amplifier to remain in an ON state for longer continuous periods. This combining approach reduces the frequency of ON/OFF transitions while maintaining the same total data transmission capacity, thereby resolving the contradiction between network adaptability and energy consumption.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent implements dynamic scheduling that adapts the transmission schedule based on traffic conditions. The system dynamically determines which timeslots to transmit data in, consolidating them into contiguous blocks, thus providing adaptability to varying traffic demands while minimizing energy consumption through reduced PA transitions.

Inventive Principle:

Principle #15Dynamics

2Use of energy by moving object

If the power amplifier is kept ON continuously to avoid transition overhead, then energy consumption is reduced, but transmission efficiency decreases

Engineering Contradiction:

Improveenergy consumptionVSAvoidtransmission efficiency

Core Design Contradiction:

Use of energy by moving objectVSProductivity

Solution Approach 1:

The patent segments the transmission timeslots into contiguous blocks rather than using frequent small noncontiguous transmissions. This segmentation strategy allows the PA to operate efficiently in continuous blocks, reducing transition overhead while maintaining high transmission efficiency by concentrating data transmission in well-defined time periods.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If transmission timeslots are kept noncontiguous to match traffic patterns, then network flexibility is improved, but the number of PA transitions increases

Engineering Contradiction:

Improvenetwork flexibilityVSAvoidenergy loss

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent performs preliminary scheduling of transmission timeslots to consolidate them into contiguous blocks before transmission. This advance planning allows the system to maintain flexibility in handling different traffic patterns while pre-organizing transmissions to minimize PA transitions, thereby reducing energy loss.

Inventive Principle:

Principle #10Preliminary action

AI summary

Systems and methods of scheduling traffic perform or comprise receiving a data frame, the data frame including a series of timeslots ordered according to an unordered schedule, wherein the series of timeslots includes at least two noncontiguous groups of data timeslots; calculating a revised schedule for the data frame, wherein the revised schedule differs from the unordered schedule in at least one of a time domain characteristic or a frequency domain characteristic; rearranging the timeslots of the data frame according to the revised schedule in at least one of the time domain or the frequency domain, such that the revised schedule includes fewer transmission periods than the unordered schedule; and causing a transmitter of the telecommunications network to transmit the data frame according to the revised schedule.
