Solution Overview

Problem

Existing wireless communication systems face challenges in efficiently managing repeaters to communicate with multiple upstream nodes, leading to conflicts in control information and communication direction configurations.

Innovation Solution

The implementation of a method where repeaters establish control connections with multiple upstream nodes to receive control information, including TDD patterns, and provide repeater functions between upstream and downstream nodes, while resolving conflicts in control information and communication direction configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If repeaters communicate with multiple upstream nodes, then system capacity is improved, but conflicts in control information occur

Engineering Contradiction:

Improvesystem capacityVSAvoidcontrol information consistency

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent segments control information handling by introducing a primary upstream node and secondary upstream nodes. The primary node manages TDD pattern configuration and control information, while secondary nodes handle only data transmission. This segmentation resolves conflicts by establishing a clear hierarchy in control information management.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a mediator mechanism where the primary upstream node acts as an intermediary between secondary upstream nodes and the repeater. The primary node receives control information from secondary nodes and coordinates TDD patterns, preventing direct conflicts while enabling multiple upstream node connections.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of time

If repeaters use multiple upstream nodes, then forwarding latency is reduced, but device complexity increases

Engineering Contradiction:

Improveforwarding latencyVSAvoidcontrol connection management

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The patent merges control functions into a single primary upstream node while maintaining multiple data transmission paths through secondary upstream nodes. This combining approach reduces forwarding latency by enabling parallel data paths while simplifying control management by consolidating TDD pattern configuration in one node.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The primary upstream node performs multiple functions: it manages TDD patterns, receives control information from secondary nodes, and coordinates communication timing. This multi-functionality reduces the need for separate control mechanisms, thereby reducing overall device complexity while supporting multiple upstream nodes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Aspects described herein relate to establishing a control connection with at least a first node for receiving control information for providing a repeater function for two or more upstream nodes, communicating control information over the control connection from at least the first node, and providing, based on the control information, the repeater function between at least a first upstream node of the two or more upstream nodes and at least one downstream node and between at least a second upstream node of the two or more upstream nodes and the at least one downstream node or at least another downstream node.
