Solution Overview

Problem

Current communication technologies face limitations in configuring the Remaining Minimum System Information (RMSI) control resource set and its associated SS/PBCH block to occupy the same beam in frequency division multiplexing mode, restricting flexibility and applicability to various scenarios.

Innovation Solution

The method involves determining configuration parameters for the RMSI CORESET and SS/PBCH block, including frequency-domain offset parameters, to ensure they share the same beam, with parameters such as bandwidth, time-domain symbols, and frequency-domain position being aligned or offset in a way that allows flexible configuration and broader applicability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the RMSI CORESET and SS/PBCH block are configured to occupy the same beam in frequency division multiplexing mode, then the compatibility with analog beam scanning mode is improved, but the configuration flexibility is limited by the 8-bit maximum bit width constraint

Engineering Contradiction:
Improvecompatibility with analog beam scanning modeVSAvoidconfiguration parameter complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The configuration information is divided into two parts: a first configuration information part (5 bits) indicating the frequency-domain offset relationship between RMSI CORESET and SS/PBCH block, and a second configuration information part (3 bits) indicating the time-domain symbol duration. This segmentation allows the system to achieve flexible configuration within the 8-bit constraint while supporting multiple deployment scenarios including analog beam scanning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a frequency-domain offset parameter that can take on different values (0, 1, or 2) to indicate different frequency relationships between RMSI CORESET and SS/PBCH block. This parameter change approach enables the system to adapt to various beam scanning configurations without exceeding the 8-bit limitation, thereby improving versatility while managing configuration complexity.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the RMSI CORESET and SS/PBCH block use frequency division multiplexing mode, then the transmission efficiency is improved, but the configuration flexibility for different frequency bandwidths is reduced

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidconfiguration flexibility for different frequency bandwidths
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent makes the frequency-domain offset configuration dynamic by allowing the offset value to be selected from multiple predefined options (0, 1, or 2) based on the actual frequency bandwidth and deployment scenario. This dynamic configuration approach enables the system to maintain high transmission efficiency through FDM while adapting to different frequency bandwidth conditions, thereby resolving the contradiction between efficiency and flexibility.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If the frequency-domain position offset between RMSI CORESET and SS/PBCH block is configured with fine granularity, then the configuration precision is improved, but the number of configuration bits required increases

Engineering Contradiction:
Improvefrequency-domain position configuration precisionVSAvoidconfiguration bit width
Core Design Contradiction:
Manufacturing precisionVSLoss of information

Solution Approach 1:

Instead of providing full fine-grained frequency offset configuration (which would require more than 8 bits), the patent applies partial action by providing a limited set of predefined offset values (0, 1, or 2). This partial configuration approach achieves sufficient precision for practical deployment while strictly adhering to the 8-bit information constraint, effectively resolving the contradiction between precision and information loss.

Inventive Principle:
Principle #16Partial or excessive action
