Solution Overview

Problem

In radio communication systems, network devices struggle to determine an optimal access manner for terminals due to coverage holes and changing transmission environments, despite terminals supporting multiple access methods.

Innovation Solution

Terminals perform measurements on multiple beams generated by a network device using the same transmit spatial filter and report measurement results and access state information to the network device, allowing it to determine direct or indirect access manners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the terminal supports multiple access manners for accessing the network device, then the adaptability of the terminal is improved, but the network device cannot determine the access manner, resulting in loss of information

Engineering Contradiction:

Improveaccess manner supportVSAvoidaccess manner determination

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The terminal performs measurements on multiple beams and feeds back measurement results and access state information to the network device. The network device uses this feedback to determine the access manner, resolving the information loss problem while maintaining multi-access adaptability

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Measurement results and access state information serve as intermediaries between the terminal and network device. These intermediate data elements enable the network device to infer the optimal access manner without direct terminal indication

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If the terminal reports measurement results of multiple beams, then the measurement precision is improved, but the quantity of information to be processed increases

Engineering Contradiction:

Improvebeam measurement accuracyVSAvoidinformation quantity

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The terminal extracts only the most relevant measurement results and access state information from multiple beam measurements, reporting only necessary data to the network device. This reduces information quantity while preserving measurement precision for access manner determination

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The terminal performs measurements on M beams where N beams use the same transmit spatial filter, reporting results strategically. This partial measurement approach provides sufficient precision for access determination without processing all possible beam data

Inventive Principle:

Principle #16Partial or excessive action
