Dynamic C-RAN Downlink Reuse Using UE Signature Vectors

The system pre-calculates and stores signature vectors for each UE based on historical signal reception metrics before spatial reuse decisions are needed. When a UE establishes a new connection, the system checks if a stored signature vector matches the initial signal reception metrics, and if so, initializes the signature vector using the stored data. This preliminary preparation enables faster spatial reuse management without real-time computational overhead.

The system creates and stores signature vectors that represent the signal reception characteristics of each UE at different radio points. These signature vectors are copied and reused when the same UE reconnects, allowing the system to quickly determine appropriate radio point subsets without重新 calculating from scratch, thereby increasing spatial reuse opportunities while maintaining manageable complexity.

The system pre-computes signature vectors containing signal reception metrics for each UE at multiple radio points before spatial reuse decisions are required. These pre-computed vectors are stored and reused, eliminating the need for real-time computation of signal metrics when managing radio point subsets, thus reducing processing load while enabling dynamic spatial reuse management.

The system transforms raw signal reception metrics into compact signature vector representations that capture the essential characteristics of UE-radio point relationships. By changing the parameter representation from detailed signal measurements to condensed signature vectors, the system reduces processing requirements while maintaining the ability to dynamically manage radio point subsets for spatial reuse.

The system updates signature vectors periodically or at specific events (such as when a UE establishes a new connection) rather than continuously tracking UE movement. This periodic update approach maintains sufficient accuracy for spatial reuse decisions while avoiding the time loss and processing overhead associated with continuous updates.

When a UE reconnects, the system checks if a previously stored signature vector matches the initial signal reception metrics. If a match is found, the system copies and reuses the stored signature vector without performing new measurements or calculations, thereby maintaining measurement precision while minimizing time loss and processing overhead.
