MBS Reception Reporting for Non-Serving Cell Broadcast Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UE and base station operations face inefficiencies when receiving broadcast services from non-serving cells, leading to resource wastage and suboptimal service delivery.
Innovation Solution
UE reports its capability and reception status of broadcast services from non-serving cells to the serving base station, allowing for coordinated service delivery through shared receiver resources and scheduling adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UE receives broadcast service from non-serving cell, then service availability is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the UE reports its broadcast service reception status from non-serving cells to the serving base station. This feedback loop enables the network to monitor resource utilization efficiency and adjust scheduling decisions accordingly, resolving the contradiction between service availability and resource utilization efficiency.
Solution Approach 2:
The patent introduces dynamic scheduling adjustments where the serving base station modifies its broadcast service allocation based on real-time UE reception status reports. This dynamic adaptation allows the system to optimize resource distribution while maintaining service availability, addressing the efficiency-versus-availability trade-off.
2Productivity
If UE reports broadcast service status to serving base station, then resource allocation optimization is improved, but signaling overhead increases
Solution Approach 1:
The patent applies partial action by having the UE report only essential broadcast service status information (such as reception status and quality metrics) rather than complete operational details. This selective reporting approach optimizes resource allocation while minimizing signaling overhead, resolving the contradiction between optimization effectiveness and signaling burden.
3Area of stationary object
If broadcast service is delivered from non-serving cell, then service coverage is improved, but coordination complexity increases
Solution Approach 1:
The serving base station acts as an intermediary that coordinates between the non-serving cell (where broadcast service is actually delivered) and the UE. This intermediary role simplifies the overall coordination complexity by centralizing the management function, allowing extended service coverage without proportionally increasing system complexity.

AI summary
The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. An embodiment of the present invention provides operations of a UE and a base station in a situation in which the UE can be provided with an MBS in a non-serving cell. A method for operating a UE in a wireless communication system according to the present disclosure may comprise the steps of: receiving instruction information related to a broadcast service-related information report from a first base station corresponding to a serving cell of the UE; transmitting, to the first base station, UE capability information regarding whether a broadcast service can be received from a non-serving cell; and transmitting, to the first base station, information regarding a broadcast service which the terminal currently receives, or information regarding a broadcast service which the UE wishes to receive.
