Solution Overview

Problem

Existing communication technologies face high signaling overhead due to resource configuration through DCI or RRC signaling for uplink and downlink transmissions in Time Division Duplex (TDD) mode, leading to issues with coverage, latency, and capacity in non-overlapping sub-band full duplex systems.

Innovation Solution

The method involves determining the location and/or size of transmission resources based on predefined or network-configured relationships between resources before and after switching, reducing the need for DCI or RRC signaling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If resources are configured through DCI or RRC signaling, then transmission resources can be allocated, but signaling overhead increases

Engineering Contradiction:
Improvesignaling overheadVSAvoidresource configuration
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The terminal determines the location of transmission resources after switching based on location relationships between transmission resources, terminal information, or pre-configured locations, without requiring explicit DCI or RRC signaling for each resource allocation. This self-determination mechanism eliminates the need for continuous network signaling while maintaining proper resource allocation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Location relationships and size relationships between transmission resources are pre-configured or predefined before switching occurs. The terminal uses these pre-established relationships to automatically determine resource locations after switching, avoiding the need for real-time signaling during operation.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If transmission resources are reconfigured after switching, then resource allocation can be optimized, but retransmission interruptions occur

Engineering Contradiction:
Improveresource allocation efficiencyVSAvoidtransmission continuity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The terminal determines the location of transmission resources after switching based on pre-configured location relationships or relationships with activated full-duplex PDCCH resources before switching occurs. This allows seamless resource allocation without retransmission interruptions, as the terminal already knows where to transmit after switching.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Location relationships and relationship parameters act as intermediaries between the network device and terminal for resource allocation. Instead of direct signaling that causes interruptions, these relationship parameters enable indirect, continuous resource determination that maintains transmission reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If detailed resource configuration signaling is used, then resource allocation precision is improved, but signaling overhead increases

Engineering Contradiction:
Improveresource allocation precisionVSAvoidsignaling overhead
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The terminal self-determines precise resource locations using relationship parameters and pre-configured information, eliminating the need for detailed explicit signaling from the network. The precision is maintained through the terminal's autonomous calculation based on established relationships rather than direct network instructions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent extracts only the essential relationship parameters and pre-configured location information needed for resource determination, removing unnecessary detailed signaling. The terminal uses these minimal extracted parameters to precisely determine resource locations without requiring comprehensive signaling.

Inventive Principle:
Principle #2Taking out (Extraction)
