AI Technical Summary

Technical Problem

In New Radio (NR) communication, the cell handover delay is large, which affects system performance. The terminal has a high complexity during cell handover, making it difficult to achieve low latency and high success rate handover.

Method used

By receiving and sending signaling including the first and second parameters corresponding to the target element, specifically including physical cell identification PCI, subcarrier interval and frequency domain absolute information ARFCN-ValueNR, flexible switching of the serving cell, serving cell group or TCI state group is realized, reducing the complexity of the high-level protocol of the terminal.

Benefits of technology

This method enables the base station side to flexibly switch multiple channels or signal combinations. The terminal only needs to maintain a high-level protocol stack to reduce cell handover delay, improve handover success rate, and reduce the complexity of the terminal.
