COT Shared Resource Blocking by Service Type for Collision Control
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, particularly when multiple services 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 service-type-based blocking, then resource allocation flexibility is maintained, but resource utilization efficiency deteriorates and collisions increase
Solution Approach 1:
The COT shared resource pool is segmented into multiple resource blocks, where each resource block is specifically configured for a particular service type (e.g., URLLC, eMBB, mMTC). This segmentation ensures that resources are systematically organized by service requirements, improving allocation efficiency and reducing collisions between different service types while maintaining manageable complexity through structured organization.
2Reliability
If multiple service types share the same COT resources simultaneously, then resource flexibility is improved, but resource collisions increase and transmission reliability deteriorates
Solution Approach 1:
Different resource blocks within the COT shared resource pool are assigned with different service-type-specific characteristics and configurations. Each resource block has optimized parameters tailored to its designated service type (e.g., latency constraints for URLLC, throughput for eMBB), ensuring high transmission reliability for each service while maintaining overall system versatility through the diverse resource block portfolio.
3Manufacturing precision
If COT shared resources are allocated dynamically without service type consideration, then allocation speed is maintained, but resource allocation precision deteriorates
Solution Approach 1:
Resource blocks are pre-configured and pre-marked with their designated service types and corresponding resource requirements before actual resource allocation occurs. This preliminary organization allows the terminal device to quickly identify and allocate appropriate resources based on service type matching, achieving both high allocation precision and maintained speed through efficient pre-structured resource management.

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.
