Solution Overview

Problem

Existing device-to-device (D2D) communication protocols lack efficient mechanisms for associating, connecting, and managing multiple wireless transmit/receive units (WTRUs) to provide a unified service experience across multiple devices simultaneously.

Innovation Solution

A method for WTRUs to transmit registration requests for aggregation, receive aggregation-related information, and establish sidelink communication with multiple WTRUs, involving WTRU identifiers, time windows, and subscriber identifiers, with support for single or multiple simultaneous aggregations, and includes mechanisms for revocation and resource release.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If D2D communication protocols are used for multiple devices, then device connectivity is enabled, but efficient management and association mechanisms are lacking

Engineering Contradiction:
Improvedevice association capabilityVSAvoidmanagement complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple WTRUs into a single aggregation group managed by one lead WTRU. The lead WTRU consolidates registration requests and manages the aggregation group, reducing individual device complexity while enabling collective adaptability for unified service experiences across multiple devices.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lead WTRU performs multiple functions including registration management, aggregation coordination, and service provisioning for the entire aggregation group. This universal role simplifies the system by having one device handle diverse management tasks that would otherwise require complex coordination among all devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If multiple WTRUs are aggregated for unified service, then service experience is improved, but communication overhead and management signaling increase

Engineering Contradiction:
Improveunified service experienceVSAvoidsignaling overhead
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The lead WTRU acts as an intermediary between the network and other aggregation group members. It receives registration requests from the network and distributes them to member WTRUs, consolidating signaling traffic and reducing the overall communication overhead while maintaining unified service delivery.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the aggregation management into hierarchical levels: network-level registration and device-level participation. This segmentation allows the network to manage aggregations broadly while individual WTRUs handle specific service operations, reducing signaling overhead by distributing management responsibilities appropriately.

Inventive Principle:
Principle #1Segmentation

3Reliability

If aggregation registration is implemented, then device association is enabled, but revocation and resource release mechanisms are needed

Engineering Contradiction:
Improveaggregation managementVSAvoidrevocation process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements feedback mechanisms where the network provides revocation notifications to the lead WTRU, which then coordinates resource release with aggregation group members. This feedback loop ensures reliable aggregation management by maintaining synchronized state information while simplifying the revocation process through centralized notification.

Inventive Principle:
Principle #23Feedback
