Terminal Resource Type Determination for Flexible TDD Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face challenges in flexibly utilizing transmission resources for uplink transmission in TDD mode, particularly in non-overlapping sub-band full duplex systems, where resources cannot be used for multi-slot transmission or retransmission.
Innovation Solution
The proposed solution involves determining a valid resource type for scheduled transmissions based on target information, which includes indication information of resource types and/or type information of transmission resources. This allows for flexible utilization of transmission resources by identifying valid resource types for uplink and downlink transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If non-overlapping sub-band full duplex is used to solve coverage and capacity problems, then uplink transmission coverage and capacity are improved, but transmission resource flexibility deteriorates
Solution Approach 1:
The patent introduces dynamic resource type indication mechanisms where the network device can flexibly indicate different resource types (first type for uplink sub-band, second type for flexible symbols, third type for all uplink slots) through DCI or RRC configuration. This allows the system to adapt resource allocation dynamically based on traffic conditions while maintaining the non-overlapping sub-band structure, thus resolving the contradiction between fixed resource allocation and transmission flexibility.
Solution Approach 2:
The patent changes the parameter of resource type indication by introducing multiple resource type categories and using indication bits to switch between them. The network device can indicate different resource types for different transmissions, allowing flexible utilization of transmission resources including multi-slot transmissions and retransmissions, thereby improving adaptability without sacrificing the capacity benefits of non-overlapping sub-band full duplex.
2Reliability
If protocol-based transmission scheduling is used to ensure reliable communication, then transmission reliability is improved, but resource utilization flexibility deteriorates
Solution Approach 1:
The patent creates a universal resource indication mechanism that can handle multiple transmission scenarios (initial transmissions, retransmissions, multi-slot transmissions) through a unified resource type indication framework. The indication mechanism works across different transmission types including PUSCH, PUCCH, and PDSCH, providing both reliable protocol-based scheduling and flexible resource utilization through the same infrastructure.
