Unicast BWP Common Frequency Resource Allocation for 5G MBS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G communication systems face challenges in efficiently managing resource allocation for multicast and broadcast services, which are critical for supporting diverse user equipment (UE) requirements and network conditions, particularly in transitioning between different service modes and coverage areas.
Innovation Solution
The proposed solution involves a method and apparatus for resource allocation in 5G wireless communication systems that allow User Equipment (UE) to dynamically receive multicast and broadcast services by configuring bandwidth parts (BWP) and common frequency resources (CFR) based on configuration information received from the base station, enabling flexible switching between unicast and multicast/broadcast modes, and utilizing carrier aggregation for efficient resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multicast and broadcast services are provided using separate dedicated resources, then service reliability is improved, but network resource utilization efficiency deteriorates
Solution Approach 1:
The patent combines multicast and broadcast service resources with unicast bandwidth parts (BWPs) by configuring common frequency resources (CFRs) within the unicast BWP framework. This merging allows shared resource pool utilization while maintaining service-specific quality of service (QoS) parameters, thereby improving resource utilization efficiency without compromising service reliability
Solution Approach 2:
The patent creates a universal resource allocation mechanism where the unicast BWP structure serves multiple functions: it provides dedicated resources for unicast services while simultaneously hosting common frequency resources for multicast and broadcast services. This multi-functionality eliminates the need for completely separate resource pools, improving overall network efficiency
2Adaptability or versatility
If dynamic switching between unicast and multicast/broadcast modes is enabled, then service adaptability is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic service mode switching by configuring bandwidth parts that can be activated or deactivated based on service requirements. The network can dynamically allocate common frequency resources within unicast BWPs and switch between service modes without requiring separate dedicated infrastructures, thereby improving adaptability while controlling complexity through standardized BWP management procedures
3Adaptability or versatility
If common frequency resources are configured within unicast BWP, then resource allocation flexibility is improved, but service continuity during BWP switching deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-configuring common frequency resources and their associations with unicast BWPs before service delivery begins. The network establishes BWP configurations, CFR allocations, and service mappings in advance through RRC signaling, enabling rapid service mode switching without interrupting ongoing multicast or broadcast services, thus maintaining service continuity while preserving allocation flexibility
