Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wireless communication systems face challenges in efficiently managing configured grant physical uplink shared channels (CG-PUSCH) due to the lack of clear indications about their transmission, leading to increased complexity and resource consumption at network nodes.

Innovation Solution

The proposed solution involves transmitting an indication of whether a CG-PUSCH is to be transmitted prior to its first configured symbol, allowing network nodes to reduce blind decoding hypotheses and optimize resource usage through beamforming.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If network nodes perform blind decoding to detect CG-PUSCH transmissions without prior indication, then the system maintains flexibility in transmission decisions, but processing complexity and resource consumption increase significantly

Engineering Contradiction:

Improvetransmission flexibilityVSAvoidprocessing complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by transmitting an indication signal before the actual CG-PUSCH transmission. This indication is sent in advance to inform the network node whether a CG-PUSCH will be transmitted, allowing the network node to prepare accordingly and avoid performing blind decoding when unnecessary, thus reducing processing complexity while maintaining transmission flexibility

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary indication signal that mediates between the UE transmission decision and the network node reception process. This indication acts as a intermediary message that carries transmission intent information, enabling the network node to optimize its processing resources without sacrificing the ability to handle dynamic transmission scenarios

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If network nodes monitor multiple beams simultaneously for CG-PUSCH, then reception reliability improves, but resource consumption and processing load increase

Engineering Contradiction:

Improvereception reliabilityVSAvoidresource consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The indication transmitted in advance allows the network node to determine which beam to monitor based on the indicated transmission information. Instead of simultaneously monitoring multiple beams, the network node can focus resources on the specific beam associated with the indicated CG-PUSCH transmission, maintaining reliability while reducing energy consumption

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies local quality by directing monitoring resources to specific localized beams rather than uniformly monitoring all possible beams. The indication provides information that allows the network node to concentrate reception efforts on the relevant spatial direction, optimizing the distribution of monitoring resources across different beam directions

Inventive Principle:

Principle #3Local quality
