Engineering Contradiction Analysis
1Productivity
If traditional wireless communication methods are used for multicast broadcast services, then system complexity is reduced, but resource allocation efficiency and data transmission reliability deteriorate in beam-based scenarios
Solution Approach 1:
The patent segments the multicast broadcast service into beam-specific counting indications, where each beam can independently manage its own service delivery and counting. This allows resource allocation to be optimized per beam without requiring complex system-wide coordination, thus improving resource allocation efficiency while maintaining manageable system complexity through localized decision-making.
2Reliability
If beam-based counting indication is implemented for multicast broadcast services, then data transmission reliability and resource utilization are improved, but signaling overhead and system complexity increase
Solution Approach 1:
The patent merges the counting indication functionality directly into the existing beam management procedures. By combining the service delivery indication with the beam-specific counting mechanism, the system achieves reliable data transmission tracking without requiring separate signaling messages, thereby reducing signaling overhead while maintaining high reliability.
3Measurement precision
If multiple beam-specific counting indications are maintained simultaneously, then service delivery accuracy for different beams is improved, but memory resources and processing overhead increase
Solution Approach 1:
The patent establishes beam-specific counting indications in advance as part of the beam setup procedure. By pre-configuring the counting mechanisms for each beam before service delivery begins, the system achieves accurate service delivery tracking without requiring complex real-time calculations or large memory buffers, thus maintaining measurement precision while minimizing memory resource consumption.

AI summary
A system, method and apparatus for wireless communications is provided. A user equipment (UE) transmits to a base station, a first message comprising a first field and a second field. The first field corresponds to information associated with receiving data of at least one MBS service. The second field associated with receiving data of the at least one MBS service via at least one first beam. The UE then receives data of the at least one MBS service via the at least one first beam.
