Shared CORESET Configuration for RedCap Scheduling Flexibility

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional approaches for configuring CORESETs in wireless communication networks face challenges with RedCap UEs, which have limited bandwidth, leading to reduced scheduling flexibility for base stations due to the need for specific CORESETs, affecting the scheduling of full-capability UEs.

Innovation Solution

Configure full-capability UEs with a set of CORESETs in a BWP slot and RedCap UEs with a subset or partial CORESETs within the BWP of the full-capability UEs, allowing RedCap UEs to share CORESETs and reducing the number of CORESETs required, thereby enhancing scheduling flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate CORESETs are configured for RedCap UEs, then RedCap UEs can operate within their limited bandwidth, but the number of CORESETs increases and scheduling flexibility is reduced

Engineering Contradiction:

Improvebandwidth adaptabilityVSAvoidnumber of CORESETs

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single CORESET is configured to serve both full-capability UEs and RedCap UEs simultaneously. The CORESET structure includes frequency domain resources that can accommodate different bandwidth requirements, allowing one CORESET to fulfill multiple functions for different UE types without requiring separate dedicated CORESET configurations

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Within the shared CORESET, different frequency domain resource allocations are assigned to different UE types. Full-capability UEs receive broader frequency resources while RedCap UEs receive narrower frequency resources within the same CORESET structure, allowing each UE type to access appropriately sized resources from the same pool

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If separate CORESETs are configured for RedCap UEs, then RedCap UEs can operate within their limited bandwidth, but scheduling flexibility for base stations is reduced

Engineering Contradiction:

Improvebandwidth adaptabilityVSAvoidscheduling flexibility

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The shared CORESET structure enables the base station to schedule both full-capability UEs and RedCap UEs using a single CORESET configuration, maintaining scheduling flexibility while accommodating different bandwidth requirements through dynamic resource allocation within the unified CORESET framework

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If full CORESETs are allocated to RedCap UEs, then RedCap UEs can access control channels, but bandwidth resources are wasted beyond their capability

Engineering Contradiction:

Improvecontrol channel accessVSAvoidbandwidth waste

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The CORESET configuration uses local quality by allocating different frequency domain resource sizes within the same CORESET structure. RedCap UEs are assigned frequency resources matching their bandwidth capability, while full-capability UEs receive broader resources, ensuring each UE type accesses only the bandwidth it can effectively utilize without waste

Inventive Principle:

Principle #3Local quality

AI summary

A wireless communication network, has one or more first user devices, UEs, and one or more second user devices, UEs. The wireless communication network is to configure the first UE with one or more bandwidth parts, BWPs, and with a set of control resource sets, CORESETs, within the BWP in the same slot, and the wireless communication network is to configure the second UE with only a subset from the set of CORESETs.
