Solution Overview

Problem

Existing wireless communication systems face limitations in communication flexibility and efficiency, particularly in managing downlink and uplink transmissions, which affect the performance of user equipment and base stations.

Innovation Solution

Implementing a system where user equipment and base stations utilize multiple control resource sets (CORESET pools) and transmission configuration indication states to efficiently manage downlink control information (DCI) and physical uplink shared channel (PUSCH) transmissions, allowing for enhanced control over downlink and uplink operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single control resource set (CORESET) pool is used for downlink control information transmission, then the system structure remains simple, but communication flexibility and efficiency are limited

Engineering Contradiction:
Improvecommunication flexibilityVSAvoidsystem structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the control resource set into multiple pools (first CORESET pool and second CORESET pool), where each pool can be independently configured and managed. This segmentation allows the system to handle different downlink control information separately, improving flexibility and adaptability while maintaining manageable complexity through structured organization

Inventive Principle:
Principle #1Segmentation

2Productivity

If multiple transmission configuration indication (TCI) states are configured for different CORESET pools, then transmission efficiency and adaptability improve, but configuration complexity increases

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidconfiguration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies different TCI states to different CORESET pools based on their specific requirements. Each CORESET pool can be associated with specific TCI states that are optimized for its particular transmission characteristics, allowing localized optimization of transmission efficiency without requiring uniform complex configuration across the entire system

Inventive Principle:
Principle #3Local quality

3Measurement precision

If separate CORESET pools are implemented for different DCI transmissions, then control precision and management capability improve, but the number of required components increases

Engineering Contradiction:
Improvecontrol precisionVSAvoidnumber of components
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent designs the multiple CORESET pools to share common infrastructure and management mechanisms. While separate pools provide precise control over different DCI transmissions, they utilize shared resources and coordinated management structures, reducing the overall number of independent components needed compared to completely separate systems

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A user equipment (UE) is described. Receiving circuitry receives first information and second information. Monitoring circuitry monitors downlink control information (DCI) carried by a physical downlink control channel (PDCCH). The first information indicates information to configure a first control resource set (CORESET) pool and a second CORESET pool. The second information indicates information on a first transmission configuration indication (TCI) state for CORESETs associated with the first CORESET pool and a TCI state for CORESETs associated the second CORESET pool. The DCI carried by a first PDCCH is monitored by a CORESET associated with the first CORESET pool. The DCI carried by a second PDCCH is monitored by a CORESET associated with the second CORESET pool.
