Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Uplink performance of user equipment (UE) is impaired when a configured uplink transmission beam is not permitted due to MPE conditions, and reconfiguration of a new beam introduces latency.

Innovation Solution

The UE receives a dynamic grant for an uplink transmission that overlaps with a configured uplink transmission, allowing it to transmit the uplink transmission punctured in the configured transmission, thereby improving uplink performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the UE uses the configured uplink transmission beam, then the uplink transmission can proceed without interruption, but the transmission may be impaired when MPE conditions are not met

Engineering Contradiction:

Improveuplink transmission reliabilityVSAvoidMPE condition violations

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements dynamic beam selection by allowing the UE to switch between configured uplink transmission and punctured dynamic grant transmission based on real-time MPE condition monitoring. When MPE conditions are violated, the system dynamically transitions to using the dynamic grant with punctured transmission, ensuring compliance while maintaining uplink connectivity.

Inventive Principle:

Principle #15Dynamics

2Object-affected harmful factors

If the UE reconfigures a new beam when MPE conditions are violated, then compliance with MPE conditions is achieved, but transmission latency increases

Engineering Contradiction:

ImproveMPE condition complianceVSAvoidbeam reconfiguration latency

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent prepares multiple uplink transmission configurations in advance - both configured grants and dynamic grants are pre-configured with their respective beams. When MPE conditions are violated, the UE can immediately switch to the pre-prepared dynamic grant transmission without requiring time-consuming beam reconfiguration, thus reducing latency while ensuring MPE compliance.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If the UE transmits using the dynamic grant with punctured configured transmission, then uplink performance is improved and latency is reduced, but resource utilization becomes more complex

Engineering Contradiction:

Improveuplink transmission efficiencyVSAvoidtransmission resource management complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the uplink transmission resources into configured grants and dynamic grants, each with distinct beam configurations and MPE condition requirements. This segmentation allows independent management of each transmission type, simplifying the overall resource management despite the presence of multiple configurations. The UE can selectively activate appropriate segments based on current MPE conditions.

Inventive Principle:

Principle #1Segmentation
