CORESET Resource Grouping for Flexible RedCap Frequency Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reduction in bandwidth for reduced capability (RedCap) terminals in mobile communication networks leads to underutilization of frequency domain resources, affecting transmission performance and coverage due to the fixed allocation method of control resource sets (CORESETs).
Innovation Solution
Configuring frequency domain resources for CORESETs by receiving indication information to determine either continuous or discontinuous groups of frequency domain units, allowing for flexible granularity adjustments based on network conditions to optimize resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If bandwidth is reduced for RedCap terminals to support cost-sensitive services, then manufacturing cost is reduced and service accessibility is improved, but available frequency domain resources are reduced leading to resource underutilization
Solution Approach 1:
The frequency domain resources are segmented into multiple groups, where each group contains a set of continuous resource blocks. This segmentation allows the system to allocate resources in flexible group units rather than individual resource blocks, enabling more efficient utilization of the limited frequency domain resources available to RedCap terminals.
Solution Approach 2:
The patent introduces dynamic resource allocation where the network device can flexibly configure the number of resource blocks per group and the number of groups allocated to different terminals. This dynamic adjustment allows the system to adapt resource distribution to varying service requirements and terminal capabilities, maximizing resource utilization in reduced bandwidth scenarios.
2Ease of operation
If fixed allocation method of CORESETs is used in reduced bandwidth, then configuration simplicity is maintained, but resource utilization efficiency deteriorates and transmission performance is affected
Solution Approach 1:
The patent changes the allocation parameters from fixed to variable, allowing the number of resource blocks per group and the number of groups to be dynamically adjusted based on service requirements. This parameter flexibility enables efficient resource utilization while maintaining relatively simple configuration through standardized group-based allocation patterns.
3Ease of operation
If fixed allocation method of CORESETs is used in reduced bandwidth, then configuration simplicity is maintained, but transmission performance and coverage deteriorate
Solution Approach 1:
The dynamic resource allocation mechanism allows the system to adapt CORESET resource distribution to varying channel conditions and service requirements. By flexibly adjusting the number of resource blocks and groups, the system can optimize transmission performance and coverage for different terminal types and service scenarios while maintaining configuration simplicity through standardized allocation procedures.

AI summary
A method for configuring frequency domain resources, performed by a terminal, includes receiving indication information sent by a network device; and determining frequency domain resources occupied by a control resource set (CORESET) based on the indication information. The frequency domain resources occupied by the CORESET are one of: continuous frequency domain resource units; or at least two discontinuous groups of frequency domain resource units, and the group of frequency domain resource units is obtained by dividing a plurality of frequency domain resource units based on one of at least two granularities.
