Implementing a selective transmission reception point (TRP)-based communication approach that optimizes resource allocation and beam management for multicast and broadcast services, utilizing NR sidelink communication to enhance reliability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional wireless communication systems manage multicast and broadcast services, then basic service delivery is achieved, but resource allocation efficiency and beam management performance deteriorate
Solution Approach 1:
The system segments multicast and broadcast services into different service types (e.g., eMBB, URLLC, mMTC) and allocates dedicated TRPs and beams for each service type. This segmentation enables optimized resource allocation for each service category while maintaining reliable delivery through service-specific configurations.
Solution Approach 2:
The system dynamically selects and configures TRPs and beams based on real-time service requirements, user equipment conditions, and network state. This dynamic adaptation allows the system to optimize resource allocation efficiency for different services while maintaining the reliability needed for each service type through appropriate TRP/beam selection.
2Productivity
If selective TRP-based communication is implemented, then resource allocation efficiency improves, but system complexity increases
Solution Approach 1:
The system performs preliminary configuration of multiple TRPs and beams before service delivery, pre-establishing the infrastructure needed for selective TRP-based communication. This preliminary setup includes configuring TRP parameters, beamforming weights, and resource allocations, which simplifies the actual service delivery process while maintaining high resource allocation efficiency.
Solution Approach 2:
The system introduces an intermediary layer (such as a multicast and broadcast service function entity or base station controller) that manages TRP selection and configuration. This intermediary handles the complexity of selective TRP management, shielding the core service delivery mechanism from complexity while enabling efficient resource allocation through centralized or distributed control.
3Reliability
If selective TRP-based communication with NR sidelink is implemented, then service reliability improves, but device complexity increases
Solution Approach 1:
The system applies different complexity levels and configuration approaches to different TRPs and user equipment based on local conditions and service requirements. Rather than uniformly increasing device complexity across the board, the system selectively enhances reliability for specific services and user groups through targeted TRP selection and beam management, keeping overall device complexity manageable.
