Solution Overview

Problem

Existing wireless communications systems face inefficiencies in monitoring sensing windows, leading to poor power efficiency and high processing overhead, particularly in sidelink communications where each UE monitors sensing windows independently, resulting in increased interference likelihood.

Innovation Solution

Implement cooperative and coordinated sensing techniques where UEs monitor a portion of sensing windows based on a predefined pattern, share monitoring results, and aggregate information to maintain an accurate resource map, reducing the need for individual comprehensive sensing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If each UE monitors sensing windows independently and comprehensively, then resource selection accuracy is maintained, but power consumption increases and processing overhead increases

Engineering Contradiction:

Improveresource selection 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 portion or subset of the sensing window according to a predetermined pattern, rather than all UEs monitoring the entire sensing window independently. This segmentation reduces the monitoring burden and power consumption for each individual UE while collectively maintaining comprehensive resource selection accuracy through aggregated monitoring results from multiple UEs.

Inventive Principle:

Principle #1Segmentation

2Measurement precision

If each UE monitors sensing windows independently and comprehensively, then resource selection accuracy is maintained, but processing overhead increases

Engineering Contradiction:

Improveresource selection accuracyVSAvoidprocessing overhead

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The monitoring task is divided into segments assigned to different UEs based on predetermined patterns. Each UE processes only its assigned portion of the sensing window, significantly reducing individual processing overhead. The system aggregates results from multiple UEs to achieve comprehensive resource selection accuracy, avoiding the need for each UE to perform exhaustive independent monitoring.

Inventive Principle:

Principle #1Segmentation

3Use of energy by moving object

If UEs monitor portions of sensing windows based on predetermined patterns and share results, then power efficiency improves, but system complexity increases

Engineering Contradiction:

Core Design Contradiction:

Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The sensing window is segmented and assigned to different UEs using predetermined patterns, reducing individual power consumption. The system complexity is managed through standardized result sharing mechanisms where UEs exchange monitoring results according to defined protocols, allowing the network to benefit from distributed monitoring without requiring complex coordination overhead.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple UEs combine their individual monitoring results to form a comprehensive resource selection view. By merging the monitoring outcomes from multiple UEs who each monitor different portions of the sensing window, the system achieves complete resource awareness with reduced individual power consumption, balancing power efficiency with system complexity through result aggregation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 1:

Multiple UEs merge their monitoring results to achieve comprehensive resource selection accuracy, replacing independent exhaustive monitoring. This coordinated approach allows UEs to make informed resource selections based on aggregated system-wide information, reducing the likelihood of interference while maintaining accurate resource selection through collective monitoring efforts.

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.
