Solution Overview

Problem

There is a need for a method to configure and manage gap priorities in a MUSIM operation to prevent conflicts between a MUSIM gap and a measurement gap in wireless communication systems.

Innovation Solution

A method and device for configuring and managing MUSIM gap priorities in a wireless communication system, where a user equipment (UE) and a base station exchange MUSIM gap priority preference lists, allowing the UE to provide assistance information for gap priority preferences, represented as integer values.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If MUSIM gap priority management is implemented to prevent conflicts between MUSIM gap and measurement gap, then network communication efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvenetwork communication efficiencyVSAvoidgap priority management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The UE transmits a MUSIM gap priority preference list to the base station in advance, indicating preferred gap priorities before conflicts occur. This preliminary action allows the base station to configure appropriate gap priorities proactively, preventing conflicts between MUSIM gaps and measurement gaps before they arise, thereby improving network communication efficiency while managing device complexity through pre-planned priority assignments

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The base station receives the UE's gap priority preferences and uses this feedback information to configure and determine final gap priorities. This feedback mechanism ensures that the gap configuration reflects actual UE needs and preferences, optimizing network communication efficiency while distributing the complexity management between the UE (providing preferences) and the base station (making final configuration decisions)

Inventive Principle:
Principle #23Feedback

2Reliability

If MUSIM gap priority preference list is transmitted from UE to base station, then gap priority management is enhanced, but processing load on terminal increases

Engineering Contradiction:
Improvegap priority managementVSAvoidprocessing load on terminal
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The UE transmits a priority preference list rather than actively managing gap priorities in real-time. This partial action approach enhances gap priority management reliability by providing the base station with necessary preference information, while significantly reducing processing load on the terminal compared to continuous active management. The UE performs the minimal necessary action of transmitting preferences once, rather than continuously managing gaps

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The priority preference list acts as an intermediary mechanism between the UE and base station. Instead of the UE directly managing gap priorities (which would increase processing load), the preference list serves as a mediator that conveys UE preferences to the base station, which then makes the actual gap priority decisions. This intermediary approach enhances management reliability while keeping terminal processing load minimal

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. In an embodiment of the present disclosure, a method performed by a user equipment (UE) in a wireless communication system is provided. The method includes receiving, from a base station, a first radio resource control (RRC) reconfiguration message including information indicating that the UE is allowed to provide multi-universal subscriber identity module (MUSIM) assistance information for gap priority; and transmitting, to the base station, a UE assistance information message including a MUSIM gap priority preference list indicating MUSIM gap priorities preferred by the UE. The MUSIM gap priority preference list includes information representing respective priorities for all periodic MUSIM gap preference patterns as integer values.
