UE Feedback Driven BWP Switching for 5G Latency Reduction

The patent implements a feedback mechanism where the UE monitors network throughput and compares it against expected throughput thresholds. When the actual throughput falls below the threshold, the UE sends feedback to the network indicating the need for BWP switching. This feedback-driven approach enables faster and more accurate BWP switching decisions, reducing switching latency while maintaining manageable system complexity through standardized feedback messages and decision protocols.

The patent enables the UE to autonomously monitor its own throughput performance by comparing actual throughput against expected throughput thresholds. The UE independently determines when BWP switching is needed based on its own performance metrics, eliminating the need for complex network-side monitoring and decision-making. This self-service approach optimizes spectral efficiency and power consumption while keeping the network implementation relatively simple, as the network only needs to provide initial BWP configurations and receive standardized feedback messages.
