Measurement Gap Pattern Switching for BWP Latency Reduction

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing telecommunication systems face inefficiencies in configuring measurement gap patterns (MGPs) for user equipment (UE), leading to increased measurement latency and signaling overhead due to the need for additional downlink signaling during bandwidth part (BWP) switches and changes in quality of service requirements.

Innovation Solution

A method and apparatus for configuring MGPs by receiving configuration information and index information associated with pre-configured MGPs, allowing for efficient activation and deactivation of MGPs based on BWP changes, using downlink radio resource control (RRC) signaling and downlink control information (DCI), thereby reducing latency and signaling overhead.

1Reliability

If measurement gap patterns are reconfigured during BWP switches or QoS changes, then measurement accuracy and service quality are improved, but measurement latency and signaling overhead increase

Engineering Contradiction:

Improvemeasurement accuracyVSAvoidmeasurement latency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system pre-configures multiple measurement gap patterns (MGPs) with different parameters (gap length, repetition period, offset) before they are needed. When a BWP switch or QoS change occurs, the network can immediately activate a pre-configured MGP that matches the new requirements, avoiding the latency of real-time configuration and signaling exchanges.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically selects and switches between multiple pre-configured measurement gap patterns based on current operational conditions such as active BWP and QoS requirements. This dynamic adaptation allows the measurement configuration to optimize for current conditions without requiring time-consuming reconfiguration procedures.

Inventive Principle:

Principle #15Dynamics

2Reliability

If measurement gap patterns are reconfigured during BWP switches or QoS changes, then measurement accuracy and service quality are improved, but signaling overhead increases

Engineering Contradiction:

Improvemeasurement accuracyVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

Multiple measurement gap patterns are pre-configured and stored in the UE before needed. This eliminates the need for repeated signaling exchanges during BWP switches or QoS changes, as the UE already has the necessary configuration data locally available for immediate activation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates and stores multiple copies of measurement gap pattern configurations with different parameters. Instead of transmitting configuration data each time a change is needed, the network can simply indicate which pre-configured pattern to use, significantly reducing signaling overhead while maintaining measurement accuracy.

Inventive Principle:

Principle #26Copying
