Millimeter Wave Repeater Timing Configuration via Capability-Based Mode Selection

Solution Overview

Problem

Current wireless communication systems, particularly in millimeter wave repeaters, face challenges in determining optimal operation modes for synchronization and timing configurations, leading to inefficiencies in communication and resource management due to varying capabilities among repeaters.

Innovation Solution

A method where base stations receive information about the capabilities of millimeter wave repeaters through different interfaces, determining whether to operate in asynchronous or synchronous modes based on this information, and communicating accordingly to optimize timing configurations and resource utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If synchronous operation mode is used for millimeter wave repeaters, then timing precision and synchronization are improved, but device complexity and cost increase due to requiring precise timing capability and internal clock

Engineering Contradiction:

Improvetiming precisionVSAvoiddevice complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system dynamically selects between synchronous and asynchronous operation modes based on repeater capabilities. The base station receives capability information from the repeater and determines the appropriate operation mode, allowing the system to adapt timing configurations rather than requiring all repeaters to support synchronous mode with its complex timing requirements

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameter (synchronization mode) based on repeater capabilities. By receiving capability information and determining operation modes, the system adjusts timing parameters dynamically - using synchronous mode with precise timing when capabilities allow, and asynchronous mode when they don't, thus resolving the contradiction between timing precision and device complexity
