COT Resource Block Allocation for Service-Priority Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In unlicensed spectrum, the limited resources for channel occupancy time (COT) sharing among different types of services lead to inefficient resource allocation and potential collisions, especially when multiple services with varying priorities request resources simultaneously.
Innovation Solution
Managing COT shared resources in blocks based on service types, allowing for dynamic allocation that prioritizes resource utilization and reduces collisions by ensuring each service type has dedicated resource blocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If COT shared resources are allocated without block-based service type differentiation, then the allocation process is simple, but resource utilization is inefficient and collisions occur
Solution Approach 1:
The patent segments the COT shared resources into K resource blocks, where each resource block corresponds to a specific service type. This segmentation allows different service types to be allocated dedicated resource blocks, preventing collisions and improving resource utilization efficiency. The first terminal device determines which resource block to allocate based on the service type requested by the second terminal device.
2Reliability
If resources are allocated dynamically without service type prioritization, then allocation flexibility is high, but high-priority services may not receive timely transmission
Solution Approach 1:
The patent applies local quality by assigning different characteristics to different resource blocks based on service type. Each resource block is dedicated to a specific service type with its own transmission characteristics and priority level. This allows the system to ensure timely transmission for high-priority services while maintaining flexibility for lower-priority services through separate resource blocks.
3Productivity
If multiple service types share the same resource pool, then resource allocation is simple, but resource collisions occur and utilization decreases
Solution Approach 1:
The patent divides the shared resource pool into K separate resource blocks, with each block dedicated to a specific service type. This segmentation eliminates collisions between different service types while improving overall resource utilization. The first terminal device selects the appropriate resource block based on the service type requested by the second terminal device.

AI summary
Disclosed are a method and an apparatus for communication. One example method includes receiving, by a first terminal device from a second terminal device, a request for allocating resources in a channel occupancy time (COT) shared resource; determining, by the first terminal device based on a service type of the COT shared resource, a first resource allocated to the second terminal device in the COT shared resource; and wherein the first resource belongs to a first resource block, the first resource block is one of K resource blocks in the COT shared resource, and a priority corresponding to each of the K resource blocks is the same as or higher than a priority corresponding to the service type.
