Solution Overview

Problem

The existing resource configuration indication methods in wireless communication technologies, particularly in Internet of Vehicles, face challenges due to the large number of bits required for time domain resource indication, which affects the coverage of Sidelink Synchronization Signal Block (SL SSB).

Innovation Solution

The proposed solution involves a terminal device that sends time domain resource indication information to indicate the transmission period and the number of time domain resource units, reducing the number of bits required for this information and subsequently for the Physical Sidelink Broadcast Channel (PSBCH), thereby maintaining the coverage of SL SSB.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If detailed time domain resource configuration information is transmitted in PSBCH, then resource configuration precision is improved, but the number of bits in PSBCH increases, affecting SL SSB coverage

Engineering Contradiction:

Improveresource configuration precisionVSAvoidnumber of bits in PSBCH

Core Design Contradiction:

Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The time domain resource configuration is segmented into two parts: (1) SSB-level configuration indicating the set of candidate time domain resources, and (2) Grant-level indication selecting specific resources from the candidate set. This segmentation allows the PSBCH to carry only the compact SSB-level configuration, reducing bit length while preserving configuration precision through the two-stage indication mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension of resource indication by separating SSB-level candidate resource configuration from Grant-level specific resource selection. This dimensional separation allows the system to indicate resources through multiple stages rather than encoding all details in a single PSBCH message, thereby reducing the bit length of PSBCH while maintaining comprehensive resource configuration capability.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If comprehensive time domain resource information (period, uplink time slots, uplink symbols) is indicated, then resource configuration completeness is improved, but PSBCH bit length increases, reducing SL SSB coverage

Engineering Contradiction:

Improveresource configuration completenessVSAvoidSL SSB coverage

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The comprehensive time domain resource information is segmented into SSB-level candidate resource sets and Grant-level specific resource selections. The PSBCH carries only the SSB-level configuration which defines the candidate resource pools, while the detailed resource selection is performed at the Grant level based on these candidates. This segmentation maintains resource configuration completeness while reducing PSBCH bit length to preserve coverage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary configuration at the SSB level by defining candidate time domain resource sets before the actual resource allocation. This preliminary action establishes the framework of possible resources, allowing the Grant to simply select from pre-defined candidates rather than encoding complete resource information, thereby reducing PSBCH bit length while maintaining configuration completeness.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If dual-period configuration is supported, then system adaptability is improved, but the number of bits required for configuration increases excessively

Engineering Contradiction:

Improvedual-period configuration supportVSAvoidconfiguration bit length

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The dual-period configuration is handled through segmentation where the SSB-level configuration defines candidate resource sets for multiple periods, and the Grant-level indication selects specific resources from these candidate sets. This allows the system to support complex dual-period scenarios without proportionally increasing the bit length of PSBCH, as the detailed period-specific resource selection is deferred to the Grant level.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The SSB-level candidate resource configuration serves as a universal framework that can accommodate multiple periods and different resource patterns. By defining reusable candidate resource sets at the SSB level, the system achieves multi-functionality where the same configuration structure supports various period configurations without requiring separate detailed configurations for each period, thereby controlling bit length while maintaining adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)
