Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a lack of well-known identification and authorization approaches for network-controlled repeaters (NCRs) in wireless communication systems, which are essential for effective network management and control.

Innovation Solution

A repeater is provided with an antenna and a processor configured to transmit a random access request message to a base station, receiving a temporary ID for addressing, and a base station is equipped to allocate and transmit this ID in response, enabling identification and authorization through a random access procedure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a network-controlled repeater is introduced to extend coverage and improve communication quality, then the coverage area and signal quality are improved, but the device complexity and management overhead increase due to the lack of well-known identification and authorization approaches

Engineering Contradiction:

Improvecoverage areaVSAvoidmanagement overhead

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

The repeater autonomously performs random access to the base station and self-configures by receiving the temporary ID without requiring manual configuration or complex pre-authorization procedures. This self-service mechanism reduces management overhead while enabling coverage extension

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The random access procedure serves multiple functions simultaneously: it establishes initial contact, provides identification, and enables authorization in a single unified process. This multi-functionality reduces the need for separate management procedures and lowers overall system complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If a temporary ID allocation mechanism is implemented through random access procedure, then the identification and authorization efficiency are improved, but the signaling overhead between repeater and base station increases

Engineering Contradiction:

Improveidentification efficiencyVSAvoidsignaling overhead

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The identification and authorization processes are merged into a single temporary ID allocation step during the random access procedure. This consolidation improves efficiency by completing multiple tasks in one exchange while minimizing the amount of signaling information required compared to separate procedures

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The present disclosure relates to identification and authorization for a repeater in a wireless network. The repeater may transmit a random access request message to a base station, and receive a temporary ID for addressing the repeater from the base station, wherein the temporary ID is allocated by the base station in response to the random access request message. With use of the temporary ID of the repeater, the repeater can be identified during a random access procedure, and side control information for controlling the repeater can be correctly transmitted to the repeater from the base station.
