Resource Pre-occupation Information in Wireless Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in supporting a large number of users and devices, particularly in scenarios requiring low latency and high reliability, due to limitations in resource selection and indication mechanisms.
Innovation Solution
The proposed solution involves a method for resource indication and selection in wireless communication, where a first device communicates resource pre-occupation information (RPI) with a second device using a dedicated channel. This information is transmitted either before a specific time or within a predetermined time window, allowing for improved resource management and conflict reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If resource pre-occupation information is transmitted using existing wireless communication mechanisms, then the system can support basic communication needs, but the system cannot provide sufficient flexibility for various communication scenarios requiring low latency and high reliability
Solution Approach 1:
The patent segments resource allocation into dedicated resources for RPI transmission and normal resources for data transmission. This segmentation allows independent optimization of each resource type, enabling flexible adaptation to different communication scenarios while maintaining reliable resource allocation through dedicated channels for pre-occupation information
Solution Approach 2:
The patent implements preliminary action by transmitting resource pre-occupation information before actual resource allocation and usage. This advance notification mechanism allows receiving devices to prepare for upcoming transmissions, reducing latency and improving reliability by eliminating last-minute resource conflicts and enabling proactive resource management
2Reliability
If traditional resource selection mechanisms are used, then the system structure remains simple, but resource conflicts increase and transmission reliability decreases
Solution Approach 1:
The patent introduces resource pre-occupation information as an intermediary element between resource request and resource allocation. This intermediary carries advance notification of intended resource usage, allowing devices to resolve potential conflicts before they occur, thereby improving transmission reliability without requiring complex real-time arbitration mechanisms
Solution Approach 2:
By performing preliminary resource indication through RPI transmission, the system establishes resource reservations in advance. This preliminary action prevents resource conflicts before they happen, maintaining high transmission reliability while keeping the actual resource allocation mechanism relatively simple and straightforward

AI summary
Methods, systems, and devices for resource indication and selection schemes in wireless communication are described. In one aspect, a wireless communication method is provided to include: performing, by a first device, a first communication of a resource pre-occupation information (RPI) with a second device using a dedicated resource pre-occupied channel or control channel, and wherein when a pre-occupied resource is transmitted at a time ‘n,’ the first communication is performed i) before a time ‘n-X,’ wherein X is an integer not less than 0, or ii) during a time window ending before the time ‘n.’
