1Reliability
If continuous beam measurement is performed to ensure appropriate downlink beam transmission, then data transmission reliability is improved, but energy consumption and signaling interactions increase
Solution Approach 1:
The patent applies preliminary action by pre-calculating and pre-configuring beam switching parameters based on UE position and movement trajectory before actual beam switching is needed. The network side device determines future beam configurations in advance based on predicted UE positions, eliminating the need for continuous real-time beam measurement while ensuring reliable data transmission.
Solution Approach 2:
The patent implements feedback mechanisms where the UE reports position information and movement trajectory to the network side device. This feedback enables the network to predict future beam requirements and pre-configure beam switching, reducing the need for continuous beam measurement and lowering energy consumption while maintaining transmission reliability.
