Solution Overview

Problem

Existing wireless communication systems face challenges in accurately and efficiently transmitting and receiving signals, particularly in environments requiring enhanced mobile broadband communication, massive Machine Type Communication (MTC), and Ultra-Reliable and Low Latency Communication (URLLC), where beam configuration and resource management are critical.

Innovation Solution

A method is provided for configuring access link beams in a wireless communication system by receiving and prioritizing beam configuration information, allowing partial or complete configuration based on overlapping time resources and priority settings, with options for beam forwarding units and different subcarrier spacings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If beam configuration information is received for multiple time resources, then beam configuration completeness is improved, but device complexity increases due to priority management and conflict resolution

Engineering Contradiction:
Improvebeam configuration completenessVSAvoidpriority management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a priority parameter to beam configuration information, enabling the device to distinguish between different configuration messages. By changing the parameter space to include priority levels, the system can manage multiple time resource configurations without requiring complex manual arbitration, thus reducing operational complexity while improving configuration completeness.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The device provides feedback about received beam configuration information to the base station. This feedback mechanism allows the base station to adjust subsequent configurations based on what has been successfully received and processed, creating a closed-loop system that improves reliability while simplifying the device's processing burden through automated coordination.

Inventive Principle:
Principle #23Feedback

2Stability of the object's composition

If the forwarding unit operates for all time resources, then service continuity is improved, but energy consumption increases

Engineering Contradiction:
Improveservice continuityVSAvoidforwarding unit energy consumption
Core Design Contradiction:
Stability of the object's compositionVSUse of energy by moving object

Solution Approach 1:

The forwarding unit operates periodically rather than continuously, activating only during time resources when beam configuration information indicates service is required. This periodic operation maintains service continuity for active communications while significantly reducing energy consumption during idle periods, resolving the contradiction between stability and energy use.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The forwarding unit's operational state is made dynamic, adjusting between active and inactive states based on real-time beam configuration information and service requirements. This dynamic adaptation allows the system to maintain service continuity when needed while minimizing energy consumption during periods when services are not active, optimizing the trade-off between stability and energy efficiency.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If beam configuration information is updated frequently, then beam accuracy is improved, but processing time increases

Engineering Contradiction:
Improvebeam accuracyVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary actions by configuring beams in advance based on predicted service requirements and available resources. By preparing beam configurations before actual service needs arise, the system achieves high beam accuracy without requiring last-minute processing, thus reducing processing time while maintaining precision.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The beam configuration process is segmented into discrete, manageable units corresponding to specific time resources and service types. This segmentation allows the system to process and update beam configurations independently for each segment, improving overall processing efficiency while maintaining the accuracy required for each individual beam configuration task.

Inventive Principle:
Principle #1Segmentation
