Fronthaul Traffic Shaping for 5G RU-DU Capacity

The patent implements dynamic traffic shaping that adjusts the allocation of fronthaul resources based on real-time transmission priorities and channel conditions. The system dynamically modifies transmission parameters such as modulation and coding schemes, resource block allocations, and timing advance values to optimize the use of available fronthaul capacity without requiring additional bandwidth infrastructure.

The patent changes multiple transmission parameters including modulation order, coding rate, resource block size, and timing advance to efficiently utilize fronthaul capacity. By adapting these parameters based on transmission priority and channel state information, the system achieves high throughput with constrained fronthaul bandwidth, resolving the contradiction between transmission capacity and installation cost.

The patent segments different types of signals and channels into distinct priority classes (e.g., control signals, data signals, reference signals). Each segment is treated differently in terms of resource allocation and transmission timing. By segmenting traffic and applying priority-based resource allocation, the system ensures that critical signals maintain low latency while less critical traffic can be shaped to reduce fronthaul capacity requirements.

The patent performs preliminary actions by pre-configuring priority levels for different channels and signals, and by advance scheduling of resource blocks. The system uses timing advance values and resource allocation decisions made in advance to ensure that high-priority signals are transmitted with minimal delay, while lower-priority signals can be delayed for capacity optimization.
