NR Information Transmission Resource Segmentation for Access Collisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The congestion caused by a large number of Reduced Capability New Radio (NR) devices, such as industrial sensing devices and video surveillance devices, accessing a network simultaneously with enhanced Mobile Broadband (eMBB) and Ultra-Reliable Low-Latency Communications (URLLC) terminals, leads to access resource collisions and network congestion.
Innovation Solution
A network device sends indication information to terminals, specifying time and/or frequency domain resources, terminal types allowed to access, supported processing capabilities, and priority levels, enabling terminals to select appropriate resources and avoid collisions.

Engineering Contradiction Analysis
1Quantity of substance
If a large number of terminals (including RedCap devices, eMBB terminals, and URLLC terminals) access the network simultaneously, then the network access volume increases, but network congestion occurs and access resource collisions increase
Solution Approach 1:
The patent segments the network access resources by terminal type, dividing the access process into separate procedures for RedCap devices, eMBB terminals, and URLLC terminals. This segmentation prevents resource collisions by ensuring each terminal type uses dedicated access resources and procedures, thereby maintaining network reliability even as access volume increases.
2Device complexity
If all terminals use the same access resources, then resource utilization is simplified, but terminal access collisions increase
Solution Approach 1:
The patent applies local quality by configuring different access parameters and resources tailored to each terminal type's specific needs. RedCap devices receive optimized access configurations different from eMBB and URLLC terminals, allowing each group to access resources in a manner suited to their characteristics, thereby reducing collisions while maintaining manageable complexity through standardized type-specific procedures.
3Reliability
If indication information is sent to terminals to specify access resources, then access resource allocation is improved, but signaling overhead increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring access resources and parameters for different terminal types before actual access occurs. The network device prepares and stores access configurations for RedCap, eMBB, and URLLC terminals in advance, so that when terminals need to access, they can quickly obtain pre-prepared resource allocations, improving allocation reliability while reducing the amount of real-time signaling required.
