Solution Overview

Problem

Existing wireless communications systems face inefficiencies in power consumption and processing overhead due to inefficient monitoring of sensing windows for sidelink resource allocation, leading to potential interference and suboptimal resource selection.

Innovation Solution

Implement cooperative and coordinated sensing techniques where UEs monitor a subset of sensing windows based on a predefined pattern, sharing monitoring results to maintain an accurate resource map and reduce power consumption and processing overhead.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If all UEs monitor all sensing windows for sidelink resource allocation, then resource allocation accuracy is improved, but power consumption and processing overhead increase

Engineering Contradiction:

Improveresource allocation accuracyVSAvoidpower consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The sensing window monitoring task is segmented and distributed across multiple UEs. Each UE monitors only a specific subset of sensing windows rather than all windows, reducing individual power consumption while collectively maintaining comprehensive resource allocation accuracy through coordinated monitoring results

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each UE performs partial monitoring of sensing windows (only a subset) rather than complete monitoring. The system achieves sufficient resource allocation accuracy through the aggregated partial observations from multiple UEs, avoiding the excessive power consumption of full monitoring by each UE

Inventive Principle:

Principle #16Partial or excessive action

2Measurement precision

If all UEs monitor all sensing windows for sidelink resource allocation, then resource allocation accuracy is improved, but processing overhead increases

Engineering Contradiction:

Improveresource allocation accuracyVSAvoidprocessing overhead

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The monitoring task is segmented across multiple UEs, with each UE responsible for a specific subset of sensing windows. This segmentation reduces the processing overhead for each individual UE while maintaining overall resource allocation accuracy through the combination of distributed monitoring results

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each UE performs partial monitoring of sensing windows, processing only a subset of the total windows. The system achieves sufficient resource allocation accuracy through aggregated partial observations, avoiding the excessive processing overhead of complete monitoring by each UE

Inventive Principle:

Principle #16Partial or excessive action

3Object-affected harmful factors

If UEs monitor more sensing windows, then interference detection is improved, but power consumption increases

Engineering Contradiction:

Core Design Contradiction:

Object-affected harmful factorsVSUse of energy by moving object

Solution Approach 1:

The interference detection function is segmented across multiple UEs, with each UE monitoring specific sensing windows for interference. This distribution improves overall interference detection capability while reducing individual power consumption, as each UE only processes a portion of the total monitoring task

Inventive Principle:

Principle #1Segmentation

4Use of energy by moving object

If UEs monitor fewer sensing windows, then power consumption is reduced, but resource allocation accuracy deteriorates

Engineering Contradiction:

Core Design Contradiction:

Use of energy by moving objectVSMeasurement precision

Solution Approach 1:

The monitoring results from multiple UEs are merged and combined to achieve comprehensive resource allocation accuracy. Each UE monitors a subset of sensing windows with reduced power consumption, and the system integrates these partial observations to maintain accurate resource allocation decisions

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may monitor a set of sidelink resources for a first portion of one or more sensing windows in accordance with a monitoring pattern. The monitoring pattern may indicate a first portion of the one or more sensing windows or a second portion of the one or more sensing windows. The first UE may transmit control signaling indicating a result of monitoring the set of sidelink resources for the first portion. The first UE may transmit data to at least a second UE based at least in part on transmitting the control signaling. In some examples, the second UE, a third UE, or both may indicate a result of monitoring a third portion or a fourth portion of the one or more sensing windows.
