1Productivity

If multiple parallel transmissions are bound together to increase data rates, then system throughput is improved, but crosstalk between lines increases reducing individual line rates

Engineering Contradiction:

Solution Approach 1:

The patent measures crosstalk between lines and uses this harmful interference information to optimize power allocation and scheduling decisions. By incorporating crosstalk measurements into the optimization algorithm, the system converts the previously harmful crosstalk effect into useful information that enables better resource allocation and improved overall system performance.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Productivity

If transmit power is increased to improve data rate of one link, then that link's rate is improved, but data rates of other links are reduced

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent dynamically adjusts transmit power levels across multiple links based on real-time crosstalk measurements and system state. The optimization algorithm modifies power parameters for each link considering the interference it causes to others and the interference it receives, achieving a balanced power allocation that maximizes overall throughput while maintaining individual link performance.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system implements dynamic power allocation and scheduling that adapts to changing channel conditions and crosstalk levels. Rather than fixed power levels, the transmit power for each link is continuously adjusted based on current system state, enabling the system to respond to varying interference conditions and optimize performance in real-time.

Solution Approach 1:

The patent divides the complex scheduling problem into manageable components by measuring and categorizing crosstalk between different line pairs. The optimization algorithm processes scheduling decisions for multiple lines by breaking down the overall problem into individual link considerations, each informed by measured crosstalk levels, making the scheduling of large numbers of lines computationally feasible.

Solution Approach 1:

The patent performs preliminary measurements of crosstalk between communication lines and pre-computes optimization parameters based on these measurements. By having the optimization algorithm work with pre-measured crosstalk data, the system can rapidly determine optimal power allocations and scheduling decisions without requiring complex real-time calculations, enabling both high performance and fast response to changing conditions.
