Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing inroute transmission techniques, such as scrambled coded multiple access (SCMA), face limitations in handling expedited data with minimum latency, require apertures for transmission, cannot span across frame boundaries, and limit the number of terminals that can transmit simultaneously, leading to congestion and ineffective data transmission.

Innovation Solution

Implementing an asynchronous scrambled coded multiple access (ASCMA) technique for inroute transmission, which allows encapsulated group burst packets without time-based scheduling, enabling transmission across TDMA frame boundaries and supporting three times as many terminals simultaneously, thus optimizing bandwidth capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If SCMA technique with apertures is used for inroute transmission, then transmission can be scheduled and managed, but transmission overhead increases and flexibility is limited

Engineering Contradiction:

Improvetransmission managementVSAvoidtransmission overhead

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and removes the aperture scheduling mechanism from the SCMA technique. By eliminating the requirement for predefined apertures and time slot scheduling, the system achieves asynchronous transmission without the overhead associated with aperture management, while maintaining transmission reliability through other means such as power control and collision resolution protocols

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transitions from static aperture-based scheduling to dynamic asynchronous transmission. Terminals can transmit at any time without being constrained by predetermined time slots, allowing the system to adapt dynamically to traffic conditions and reduce latency for expedited data while managing multiple access through dynamic power control and collision handling

Inventive Principle:

Principle #15Dynamics

2Reliability

If SCMA technique with time slot scheduling is used, then transmission can be controlled, but latency for expedited data increases

Engineering Contradiction:

Improvetransmission controlVSAvoidlatency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent eliminates the need to wait for predetermined apertures or time slots before transmission. Expedited data can be transmitted immediately when it arrives, without preliminary scheduling delays. The system handles the timing and collision management asynchronously after transmission begins, rather than requiring advance scheduling

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system transitions from static time slot allocation to dynamic asynchronous transmission where terminals can transmit expedited data immediately when needed. The network manages the resulting traffic dynamically through power control and collision resolution rather than through predetermined scheduling, reducing latency while maintaining control

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If SCMA transmission is constrained to frame boundaries, then synchronization is maintained, but bandwidth utilization decreases

Engineering Contradiction:

ImprovesynchronizationVSAvoidbandwidth utilization

Core Design Contradiction:

Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent transitions from static frame-boundary constrained transmission to dynamic asynchronous transmission that can span across frame boundaries. Group bursts can start and end at any time rather than being confined to specific frame boundaries, allowing continuous utilization of the transmission medium and eliminating wasted bandwidth at frame transitions while maintaining synchronization through other mechanisms

Inventive Principle:

Principle #15Dynamics

4Reliability

If SCMA limits the number of simultaneous terminals, then collision is reduced, but transmission capacity is limited

Engineering Contradiction:

Improvecollision reductionVSAvoidtransmission capacity

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent changes the key parameter from limiting the number of simultaneous terminals to controlling transmission through power levels and asynchronous timing. By allowing more terminals to transmit simultaneously with different power levels and timing, the system increases capacity while managing collisions through power control and probabilistic resolution rather than through terminal number limitations

Inventive Principle:

Principle #35Parameter changes

AI summary

Systems and methods for facilitating an inroute transmission of data are disclosed. A system may include a processor and a memory storing instructions, which when executed by the processor, may cause the processor to receive information pertaining to a bandwidth capacity of a communication channel for an inroute transmission of data from a terminal of a plurality of terminals. The processor may determine, based on the received information and using an asynchronous scrambled coded multiple access (ASCMA) technique, a bandwidth allocation for the inroute transmission of data. The inroute to transmission may be in a form of ASCMA transmission of one or more encapsulated group burst packets.
