MSIM UE Measurement Reporting Timing for Conflicting Procedures

Solution Overview

Problem

Multi-subscriber identity module (MSIM) user equipment (UE) devices face challenges in performing measurement reporting due to conflicting procedures, leading to delays, increased system congestion, and decreased user experience in wireless communication systems.

Innovation Solution

The UE adjusts the time to trigger (TTT) and signal quality threshold by determining conditions for early or late measurement reporting, and the base station configures an adjusted TTT based on UE capability, allowing for timely measurement reporting despite unavailability due to higher priority procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the UE performs measurement reporting according to the configured TTT, then the measurement reporting is triggered based on signal quality threshold, but the MSIM UE cannot perform measurements during the TTT duration due to higher priority procedures

Engineering Contradiction:

Improvemeasurement reporting reliabilityVSAvoidmeasurement unavailability duration

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The UE performs preliminary actions by determining early whether higher priority procedures will prevent measurement completion during the TTT. The UE calculates the duration of higher priority procedures in advance and compares it with the configured TTT, allowing the UE to prepare appropriate measurement reporting timing adjustments before the TTT expires, thus avoiding measurement reporting failures.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies dynamics by making the measurement reporting timing adaptive rather than fixed. The UE dynamically adjusts the measurement reporting timing based on the actual duration of higher priority procedures and the remaining TTT. This dynamic adjustment allows the UE to flexibly schedule measurement reports at appropriate times, resolving the conflict between TTT requirements and higher priority procedure constraints.

Inventive Principle:

Principle #15Dynamics

2Productivity

If the UE transmits measurement report at the configured TTT, then the network receives timely information, but system congestion increases due to multiple UEs having similar reporting timing

Engineering Contradiction:

Improvemeasurement reporting throughputVSAvoidsystem delay

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent applies dynamics by making the measurement reporting timing adaptive rather than fixed. The UE dynamically adjusts the measurement reporting timing based on the actual duration of higher priority procedures and the remaining TTT. This dynamic adjustment allows the UE to flexibly schedule measurement reports at appropriate times, resolving the conflict between TTT requirements and higher priority procedure constraints.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The network receives feedback from the UE about the actual measurement reporting timing and adjusts network resources accordingly. This feedback mechanism allows the network to optimize resource allocation and reduce congestion by anticipating when measurement reports will be transmitted based on UE-specific procedure durations.

Inventive Principle:

Principle #23Feedback

3Ease of operation

If the UE adjusts the TTT to accommodate higher priority procedures, then measurement reporting becomes feasible, but the network receives delayed measurement information

Engineering Contradiction:

Improvemeasurement reporting feasibilityVSAvoidmeasurement reporting delay

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The UE performs preliminary actions by determining early whether higher priority procedures will prevent measurement completion during the TTT. The UE calculates the duration of higher priority procedures in advance and compares it with the configured TTT, allowing the UE to prepare appropriate measurement reporting timing adjustments before the TTT expires, thus avoiding measurement reporting failures.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies parameter changes by modifying the TTT parameter dynamically. The UE changes the effective TTT duration based on the actual duration of higher priority procedures. When higher priority procedures are detected, the UE adjusts the TTT parameter to accommodate these procedures while still aiming to report measurements as soon as possible, thus balancing feasibility and timing requirements.

Inventive Principle:

Principle #35Parameter changes

AI summary

Methods, systems, and devices for wireless communications are described. Generally, a base station may configure a user equipment (UE) with a time to trigger (TTT) and a signal quality threshold. The UE may determine whether one or more conditions are satisfied, and if so, transmit an early measurement report or ignore a conflicting procedure that renders the measurements unavailable. In some examples, a UE may receive an indication of a minimum TTT in a configuration message with the TTT and the signal quality threshold. The UE may indicate an updated timing, to a base station, based on the minimum TTT. In some examples, the base station may determine that a UE is a multi-subscriber identification module (MSIM) UE, and may configure the duration of the TTT accordingly.
