Solution Overview

Problem

Existing wireless communication systems face inefficiencies in managing transmission configuration indicator (TCI) states due to the need for scheduling grants that allocate wireless resources, leading to resource wastage and suboptimal activation/deactivation of TCI states.

Innovation Solution

Implementing non-scheduling assignments within scheduling grants to manage TCI state activation and deactivation, allowing for efficient resource allocation without assigning wireless resources, and using codepoints to indicate TCI states for multiple communications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If scheduling grants are used to manage TCI state activation, then TCI states can be controlled, but wireless resources are wasted because resources are allocated even when not needed

Engineering Contradiction:
ImproveTCI state control capabilityVSAvoidwireless resource waste
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent extracts the TCI state activation control function from the scheduling grant mechanism. By using dedicated TCI indication messages separate from resource scheduling grants, the system can control TCI states without necessarily allocating wireless resources, thus resolving the contradiction between control capability and resource waste.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the control functions by separating TCI state management from resource scheduling. TCI states are indicated through dedicated indication messages that can operate independently from resource allocation, allowing fine-grained control without proportional resource consumption.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If scheduling grants allocate resources for all TCI states, then all communications can be supported, but resource allocation becomes inefficient

Engineering Contradiction:
Improvemulti-communication supportVSAvoidresource allocation efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements partial action by allocating resources only for communications that are actually activated. Through selective TCI state indication and activation, the system supports multiple communication types without provisioning resources for all possible states, achieving efficiency while maintaining versatility.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent introduces dynamic resource allocation where resources are allocated based on actual communication needs rather than static pre-allocation. The system can dynamically activate or deactivate TCI states and corresponding resources, optimizing efficiency while supporting multiple communication scenarios.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If separate control messages are used for each TCI state, then precise control is achieved, but signaling overhead increases

Engineering Contradiction:
ImproveTCI state control precisionVSAvoidsignaling overhead
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent merges multiple TCI state indications into unified TCI indication messages that can convey multiple state indicators simultaneously. By combining control functions and using compact signaling formats, the system achieves precise control without proportional increases in signaling overhead.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates universal TCI indication mechanisms that can handle multiple TCI states through single messages. The indication framework is designed to be multi-functional, supporting various communication types and state configurations without requiring separate dedicated messages for each case.

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

AI summary

Aspects of the disclosure relate to transmission configuration indicator (TCI) state mapping for multiple transport block (TB) transmission with downlink control information (DCI). In one example, a scheduled entity may receive a scheduling grant from a scheduling entity. The scheduling grant may include scheduling assignments configured to assign wireless resources for corresponding enabled communications. The scheduling grant may further include non-scheduling assignments without assigning wireless resources. The scheduling grant may further include a codepoint including TCI state indicators mapping the scheduling and non-scheduling assignments to corresponding TCI states. The scheduled entity may further receive a control message to activate the TCI states mapped to the corresponding indicators. Other aspects, embodiments, and features are also claimed and described.
