Solution Overview

Problem

Existing wireless communication systems face challenges in supporting a broad range of wireless devices with varying capabilities and power consumption levels, particularly in establishing radio resource control connections and accessing cellular networks.

Innovation Solution

The system provides paging information for remote wireless devices to a relay wireless device, allowing the relay device to forward this information to the remote device via a relay link. This is achieved through dedicated signaling or during configured paging occasions, based on identification information for either the relay or remote device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If wireless devices are designed with low cost and low power consumption, then energy efficiency and affordability improve, but capability to establish radio resource control connections and access cellular networks deteriorates

Engineering Contradiction:

Improvepower consumptionVSAvoidcapability to establish radio resource control connections

Core Design Contradiction:

Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The patent introduces a relay wireless device as an intermediary between the remote wireless device and the cellular base station. The relay device establishes a radio resource control connection with the base station and forwards paging information to the remote device, enabling low-capability devices to access the network indirectly without requiring them to have full connectivity capabilities

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If relay links are established to enable remote device communication, then network accessibility for low-cost devices improves, but system complexity increases

Engineering Contradiction:

Improvenetwork accessibilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The relay wireless device serves as a mediator that leverages existing device-to-device communication capabilities rather than introducing entirely new infrastructure. The base station utilizes the already-established relay link for paging purposes, minimizing additional system complexity while improving network accessibility

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The relay wireless device performs multiple functions: it maintains its own radio resource control connection with the base station, establishes device-to-device links with remote devices, and forwards paging information. This multi-functionality reduces the need for separate dedicated infrastructure for remote device support

Inventive Principle:

Principle #6Universality (Multi-functionality)
