Solution Overview

Problem

Existing communication technologies face inefficiencies in block allocation and power management, particularly in ultra-wide band (UWB) systems, leading to resource waste and interference due to inconsistent block assignments and round hopping strategies.

Innovation Solution

A method for assigning specific subsets of blocks in a block-based time structure to devices, accompanied by detailed indication messages, ensuring clear block allocation and synchronization, thereby reducing power waste and interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If devices listen to all blocks in UWB communication, then communication reliability is improved, but power consumption increases

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent divides the communication blocks into different subsets and assigns specific subsets to specific devices. This segmentation allows devices to only monitor their assigned blocks rather than all blocks, reducing power consumption while maintaining communication reliability for the assigned segments.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Devices perform partial monitoring by listening only to the subset of blocks assigned to them rather than all blocks. This partial action reduces power consumption while still ensuring reliable communication for the assigned blocks.

Inventive Principle:

Principle #16Partial or excessive action

2Reliability

If round hopping is implemented to avoid interference, then communication quality is improved, but system complexity increases

Engineering Contradiction:

Improvecommunication qualityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent pre-assigns specific block subsets to specific devices before communication begins. This preliminary assignment eliminates the need for dynamic round hopping during communication, reducing system complexity while maintaining communication quality through the predetermined assignment structure.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If block assignment is made dynamic to improve allocation efficiency, then resource utilization is improved, but implementation complexity increases

Engineering Contradiction:

Improveallocation efficiencyVSAvoidimplementation complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent segments blocks into different subsets and assigns them to different devices, creating a structured allocation system. This segmentation provides clear allocation rules that improve efficiency while keeping implementation manageable through the organized subset structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent changes the parameter of block assignment from uniform to differentiated by device. By introducing device-specific subset assignments, the system achieves better allocation efficiency while the clear parameter structure keeps implementation complexity manageable.

Inventive Principle:

Principle #35Parameter changes

AI summary

In an example method, a first terminal device assigns a first subset of blocks in a set of blocks of a block-based time structure to a second device or a set of devices including the second device; and transmits to the second device, an indication message indicating that the first subset of blocks are assigned to the second device or the set of devices.
