Bandwidth Part Switching for Network Flexibility and Power Efficiency

The patent applies preliminary action by pre-configuring multiple bandwidth parts and preparing switching parameters in advance. The network node pre-establishes BWP configurations with different parameters (bandwidth, subcarrier spacing, cyclic prefix) so that when switching is needed, the UE can quickly activate a pre-prepared configuration rather than creating it from scratch, thereby reducing switching delay while maintaining network flexibility

The patent implements dynamics by enabling dynamic switching between different BWP configurations based on real-time network conditions and traffic requirements. The system dynamically adjusts bandwidth parts during operation, allowing the network to adapt to changing conditions while managing switching delays through configurable parameters and timing mechanisms

The patent applies parameter changes by modifying BWP configuration parameters (bandwidth, subcarrier spacing, cyclic prefix type) to optimize power consumption. The network can switch to narrower bandwidths or different subcarrier spacings that reduce UE power consumption for specific traffic types or channel conditions, while managing interruption effects through proper parameter selection and switching timing

The patent uses an intermediary approach by introducing configurable switching parameters and timing mechanisms that mediate between power savings and service continuity. The network node acts as an intermediary that coordinates switching events, manages timing, and ensures minimal disruption to ongoing services while achieving power optimization goals
