Solution Overview

Problem

In wireless communication networks, particularly in backhaul networks, new base stations face challenges in automatically selecting the best base station to connect to among multiple detected deployed base stations for initial access and subsequent connections, which complicates the deployment and maintenance of wireless backhaul networks.

Innovation Solution

A method and apparatus that enable a base station to detect and prioritize multiple detected base stations based on priority levels associated with synchronization communications, allowing it to initiate an access procedure with the highest-priority set and track lower-priority sets for future connections, thereby simplifying the deployment and management of wireless backhaul networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If new base stations detect multiple deployed base stations for initial access, then connection options increase, but deployment complexity increases

Engineering Contradiction:
Improveconnection optionsVSAvoiddeployment complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces priority levels as a parameter to differentiate between multiple detected base stations. Each base station is assigned a priority level (e.g., first priority, second priority) that enables the new base station to systematically select the best connection target, thereby reducing deployment complexity while maintaining multiple connection options

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements preliminary classification of base stations into different priority groups before the actual connection process. By pre-organizing detected base stations into first-priority and second-priority sets, the system eliminates the need for complex real-time decision-making during deployment, simplifying the overall process

Inventive Principle:
Principle #10Preliminary action

2Reliability

If new base stations perform repeated synchronization searches, then connection reliability improves, but network resource utilization decreases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidnetwork resource utilization
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent performs synchronization information collection and base station classification in advance, before the actual connection is needed. By pre-identifying high-priority base stations and storing their synchronization information, the system ensures reliable connections without requiring repeated searches, thus preserving network resources

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates and maintains a pre-classified list of suitable base stations with their synchronization information. This copied information can be quickly referenced during connection establishment, eliminating the need for repeated full synchronization searches while ensuring connection reliability

Inventive Principle:
Principle #26Copying

3Ease of operation

If manual configuration is used for base station connections, then deployment control improves, but deployment efficiency decreases

Engineering Contradiction:
Improvedeployment controlVSAvoiddeployment efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent enables new base stations to automatically detect, classify, and select appropriate deployed base stations for connection based on pre-defined priority criteria. This self-service mechanism eliminates the need for manual configuration while maintaining controlled deployment through systematic priority levels, thereby significantly improving deployment efficiency

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent transforms the deployment process from manual configuration to automated selection by introducing priority level parameters. The system automatically evaluates detected base stations against these parameters and makes connection decisions, achieving both control and efficiency

Inventive Principle:
Principle #35Parameter changes

AI summary

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may detect one or more base stations based at least in part on synchronization communications associated with the one or more base stations, and may determine one or more priority levels associated with the one or more base stations, wherein a given priority level, of the one or more priority levels, identifies a priority associated with initiating access to a wireless backhaul network via a respective base station of the one or more base stations. The base station may initiate, based at least in part on the one or more priority levels, an access procedure with a set of base stations of the one or more base stations. Numerous other aspects are provided.
